The technology of floor insulation with penofol in a wooden house. Insulation of floors with penofol

Foamed polyethylene.

This type is made in the form of a roll with a self-adhesive side, 2-10 millimeters thick, and appearance like a thin film with foil. It is mainly used for sheathing pipes, various shafts, roof and floor insulation. Especially often used as a substrate for underfloor heating. It has a temperature range from -160 degrees to +160 Celsius, has a high fire resistance. Popular brands are Isolon, Ecofol, Penofol and Isoflex.

Foamed polyethylene has several subspecies:

View A- covered with foil on only one side and is a classic version of insulation. Cannot be used in high humidity conditions.

View B- covered with foil on both sides, has a high density and does not require an additional protective layer from moisture.

View C– that view is covered with foil on one side, and on the other it has a self-adhesive layer

ALP- pasted over with foil on one side, and laminated with polyethylene on top. Often it is used when laying warm electric floors.

R- that type differs from others in that one side of it is embossed, covered with foil, and the other is smooth.

M- this type of insulation must be placed in several layers, since its foil is located on the smooth side, and the embossed one is open.


Super NET
- the type with the highest rates of thermal insulation properties, and can be used for many years without loss of properties.

It has a special structure, consisting of several canvases with a polyethylene foam mesh between them.


Penohome
- this insulation is made of fiberglass and mineral wool.

Its thickness is from 50 to 100 millimeters, and is sold in rolls or plates.

It is most often used as a heater between floors in ceilings, as well as for insulating saunas and baths.


Expanded polystyrene foam
- it is made in the form of gray plates, processed with foil on both sides and also has a large variation in temperature conditions.

It happens with a thickness of 5.10 and 15 millimeters. It is most often used when laying warm water floors and for insulating surfaces that are exposed to high humidity and heavy loads.

Basaltic- It is made on the basis of foil, but due to its unique technology, its temperature range is from -200 degrees to +600. It is also resistant to chemicals.

But this insulation contains phenol, which is considered unsafe for human health. The most famous brands of basalt insulation are Isover, Rockwool and Knauf.

Overview of penofol properties

Penofol is a material made from polyethylene by foaming with special reagents. This polyethylene foam is applied to a foil base, to which it reliably sticks. The foil base greatly enhances the thermal insulation properties of the material due to the reflection of thermal waves inside the room.

Therefore, penofol belongs to the class of reflective thermal insulation. This foil insulation has the following performance characteristics:

  • Small material thickness. At the same time, penofol has high thermal insulation properties. This allows you to effectively insulate small rooms where a thick layer of thermal insulation is unacceptable.
  • Multifunctionality. This heat-insulating material can be used not only for insulation, it is also recommended to be used as a hydro- or vapor barrier.
  • When used simultaneously with other heaters, penofol enhances their main characteristics.
  • The strength and durability of the material is achieved through the latest production technology. At the same time, the products are environmentally friendly: hazardous substances are not used.
  • Large temperature range of application: penofol does not deform at low temperatures (up to -55 °C) and does not melt at high temperatures (up to +110 °C).
  • Ease of installation and affordable pricing also add to the popularity of this versatile insulation.

Advice! There are several product classes: A, B and C. Class A insulation has a foil on one side, and the B series material has two. Class C insulation has a foil base on one side, and an adhesive layer on the other, which makes it easier to install in inconvenient areas.

Application area

Penofol has a versatility of application: it is used for insulation and vapor barrier not only for residential premises, but also for industrial facilities. That's far from full list where this material is used:

  • Ceiling ceilings.
  • Wall insulation.
  • Waterproofing and floor insulation.
  • Arrangement of warm balconies and loggias.
  • Thermal insulation of air ducts and technical pipelines.
  • Application in the automotive industry for thermal insulation of bodies.

As you can see, the list of applications is quite extensive. We will consider where you can use penofol with your own hands - the home area of ​​\u200b\u200bapplication.

Mounting technology

The surface of foilizolon is easily damaged, therefore, during transportation and installation, it needs to be handled with care. Depending on which part of the building or structure is to be insulated, the material laying technology is selected.

  • If it is supposed to insulate the house from the inside, then the isolon is placed between the wall and the finishing material, keeping air space between them to increase thermal efficiency.
  • The best option for fixing the insulation will be the use of wooden slats, forming a small crate on the wall. Foil isolon is fixed to it with the help of small nails. It is better to use a material that has a layer of foil on both sides (modification B). Joints in order to prevent "cold bridges" are glued with aluminum tape.

  • For thermal insulation of concrete floors, isolon is combined with another type of insulation. The latter is laid directly on concrete, between the floor joists. On top of this design, foil isolon spreads, and a floor covering is laid on it. Typically, this type of insulation is used as a substrate for a laminate. In addition to heat saving, it helps to reduce the load on the main floor, has a soundproofing effect.
  • When insulating a balcony, it is better to resort to the installation of a multilayer structure. The first layer in it is a one-sided foil isolon, laid out with a reflective layer. The next layer is a heater that can withstand increased mechanical loads, for example, polystyrene. An isolon is again laid on top of it. The laying technology repeats the principle of installing the first isolon layer. After the insulation is completed, they proceed to the device of the crate, on which they are attached Decoration Materials.

  • The easiest way to insulate a living room in apartment building, without resorting to parsing the walls, - place a layer of isolon behind the heating radiators. The material will reflect heat from the batteries, directing it into the room.
  • For floor insulation, the use of ALP modification material is optimal. Type C material is mainly used for thermal insulation of buildings for technical and domestic purposes. For heat and noise insulation of car interiors, type C isolon is usually used, combining it with special mastics.

Advantages and disadvantages of penofol

Main advantages of the material:

  • Low thermal conductivity, the coefficient of thermal conductivity of penofol varies from 0.039 to 0.051 W / (m * C).
  • The vapor permeability coefficient is 0.001 mg/(m*h*Pa).
  • Thermal reflection coefficient - from 97%.
  • Excellent sound absorption.
  • Does not absorb moisture.
  • Moisture absorption coefficient - less than 1%.
  • The material does not melt high temperatures(up to 110 degrees Celsius).
  • Small thickness.
  • Strength and durability.
  • Ease of installation.
  • Affordable price.

Penofol density can be from 25 to 50 kg/m³. When used together with other heaters, penofol significantly enhances their properties.

Disadvantages of penofol:

  • Insufficient rigidity. On top of the penofol layer, wallpaper cannot be glued or stained.
  • When attaching penofol, it is necessary to protect the electrical wiring and avoid breakdowns.
  • Bad adhesion. It is necessary to use a special adhesive or fasteners for strong adhesion to the surface.

Foil floor insulation

The variety of products in construction stores is very large and it is extremely difficult not to get confused among the entire range and choose a really high-quality effective material, the use of which will not force you to redo the entire repair in a short time, but, on the contrary, will give you the joy that it was carried out using high-quality materials .

What is reflective insulation

Foil insulation is a relatively new material on the market. Previously, the category of insulation for floors, walls, roofs was represented by a single type - mineral wool, which has a lot of drawbacks. This material gets wet, and in contact with water, it loses most of its properties. At the same time, it was difficult to work with him because of unpleasant tactile sensations, and sometimes dangerous.

Mineral wool

Foil insulation is a two-layer material, most often supplied in rolls, but sometimes it is also found in the form of plates. The layers are:

  • directly insulating material, such as polystyrene foam, polystyrene foam, penofol, etc.;
  • foil on the insulation layer, which has certain heat-reflecting qualities.

On a note! Foil insulation has special properties precisely due to the presence of a foil layer. It has the ability to reflect thermal energy and directs it into the room, does not allow it to go outside, strictly limiting the heat distribution zone.

Foil insulation for the floor consists of two layers

Also, the material covered with foil does not get wet, which means it also has certain water-repellent properties, although it cannot be used as a waterproofing coating.

Depending on the type of material from which this type of insulation is made, it can be thick and thin, it can retain heat worse or better, have different size pores in which there is air in one or another quantity.

Polyethylene foam

Laying slab material

Reflective thermal insulation in slabs

Reflective thermal insulation in slabs is mounted mainly under underfloor heating, although it can also be used as a conventional insulation. With foil mats, a floating screed is made and laid between the lags.

floating screed

Step 1. The concrete surface of the floor slabs is leveled with putty and grinding. Cleaned from dust.

Repair of defects

Step 2 Using a level gauge, mark the screed pouring line on the walls.

Step 3. A damper tape is attached to the walls along the perimeter of the room and the base is primed.

Primer application

Kermi damper tapes

Step 4. Plates are taken with a metallized coating, since aluminum is corroded by cement. Glue is applied pointwise to the base of the mats, after which the insulation is laid on the floor with the reflective layer up. When laying the insulation, the joints are carefully adjusted so that gaps do not form.

Step 5. The joints are glued with adhesive tape, and then the heat-insulating layer is poured with a screed solution. Level the mixture with a wide spatula or rule and leave to dry. After that, you can perform the laying of the final coating.

Warming along the lags

Step 1 Remove the floor covering, clean the base from debris, check the integrity of the lag, and, if necessary, repair the damaged elements.

Step 2. A waterproofing material is laid on top of the logs and fixed with a stapler with inside bars, spreading the film well on the floor. The edges of the canvases overlap by 10-15 cm.

Step 3. The space between the lags is filled with foil plates, laying them in one or two layers. The plates of the second layer must necessarily overlap the seams of the lower layer. A gap of 1.5-2 cm is left between the reflective coating and the upper edge of the log. If the gap cannot be left, a crate of 20x40 mm rails is stuffed on top of the logs.

Foil basalt mats

Step 4. Further actions depend on the type floor covering. If it is linoleum or laminate, the rough base is covered with sheet material - plywood, chipboard, OSB. If the floor is made of boards, they are stuffed directly onto the logs.

Table of the main properties of foil heat insulators

Name Properties Thermal conductivity Where applicable
Izolon Elastic material, light weight, waterproof and durable 0.040 W/mK As a substrate for laminate and linoleum, mounted under warm floors
Penofol Flexible, thin material, eco-friendly, waterproof 0.037-0.049 W/mK Can be used as a vapor barrier for conventional thermal insulation materials
Isover Non-flammable, dense heat-insulating material 0.041 W/mK For insulation of concrete and wooden surfaces
Rockwool Durable non-flammable material, resistant to deformation 0.39 W/mK Insulation of floors on logs, heat and sound insulation of walls and ceilings
Foil Styrofoam Temperature resistant, durable 0.037-0.041 W/mK For insulation of a warm water floor, insulation of a floating screed

Wood insulation along the lags

Most often, for the thermal insulation of a wooden floor, the method of insulation along the logs is used. It is quite simple, but at the same time effective, as it allows you to avoid large heat losses. This method is most relevant when insulating a floor located close to the ground.

The technology is produced in stages. First of all, we install logs made of wood with a T-shaped cut into a log house, or put them on the foundation, observing a step from 0.6 to 1 meter. We fasten boards or wooden shields under the lags - insulation will be placed on them. Next, we lay hydro and vapor barrier, but only in the case of using a certain insulation (mineral or ecowool).

Installation nuances

Proper laying of foil insulation will be possible subject to certain preparatory work. Necessary materials and tools to do the job:

  • nails with large hats;
  • stapler;
  • hammer;
  • construction tape.

During the installation of insulation, you should try not to make mistakes. He is placed metal side down. In this case, it will perform its main function - to reflect heat, preventing it from leaving the room. Then a comfortable microclimate will be maintained in the room with minimal resources.

Small air gaps between the material and the floor covering are acceptable. In this case, the insulated surface acquires higher characteristics.

It is important that the laying of the heat insulator is not overlapped. The best option is to place butt

For fixing, tape or ordinary nails are used. The choice of a specific solution largely depends on the type of foundation. If the insulation is equipped with an adhesive layer, then additional fastening methods can be omitted. After laying the sheets, joints appear. They must be glued with aluminum tape.

Work on the insulation of surfaces using foil insulation can be both dry and wet. The second option involves pouring material concrete screed. The first way is to install a waterproofing layer.

Insulation of the floor with penofol in a wooden house instruction and video of the work

Floor insulation with penofol wooden house one of the most modern and most effective ways insulation of cold surfaces in rooms. Penofol, in addition to excellent steam, heat and waterproofing properties, also has a reflective effect of 97%.

This article will consider two options for insulating wooden floors using penofol.

Applied materials and tools:

  • Wooden logs.
  • Cutting tool, for cutting wood and insulation.
  • Industrial stapler, foil tape.
  • Self-tapping screws, screwdriver.
  • Mounting foam.
  • Plywood or boards.
  • Thermal insulation, mineral wool, polystyrene, or other material.
  • Penofol group "A".
  • Measuring tool: level, tape measure.

Execution of work

Warming of wooden floors is presented in two versions:

I. Warming with the removal of the floor to the foundation is a more time-consuming, expensive and effective way:

  • Clean the foundation or subfloor of debris.
  • Lay the logs 1÷2 cm from the wall, in increments of 35÷40 mm. Logs lie along and across the room, in a log house or are fixed on the foundation with the help of anchors and between themselves with self-tapping screws.

Important! Logs and the old floor must be treated with a protective coating. . Under the bending logs, install split technological rails, or special wedges.

  • Under the bending logs, install split technological rails, or special wedges.

  • In the process of installing and fixing the lag, control the horizontal level, level.

  • If the lags were installed earlier, check their condition, replace the rotten ones.
  • Clean the surface of debris.
  • Knock boards under the boards under the logs or fasten them to the cranial bars.
  • When using a moisture-absorbing insulation to waterproof it and create the most thermal effect, install penofol on the shields and secure.
  • Unpack and cut the heat insulator. Mineral wool is cut with a margin of 5 mm per side. Plates are stacked end to end, to each other. To improve the thermal insulation properties, the insulation can be laid in several layers, with overlapping joints.

  • All gaps between the insulation and the lags must be insulated with foam or sealants.
  • Lay penofol, overlap at least 10 cm. Overlap on the walls at least 10 cm.
  • Fix penofol with an industrial stapler, it is permissible to use foil tape.

  • On top of the lag, install and secure with self-tapping screws sheets of chipboard, or a board, leaving 4 mm on the air cushion. The board lies at a distance of 1.5 cm from the wall, the first is fixed vertically, the second and subsequent from the end to the rails and the groove is installed to the groove.

Installing and fixing chipboard

  • On top of the chipboard, lay the finishing floor.

II. Warming over an existing floor, a quick way.

  • Cleaning the floor surface by replacing old boards.
  • Laying penofol, adhesive side down, foil up.

Laying penofol on the floor

  • Install slats or logs on top to form an air cushion, lay hardboard or chipboard (12 mm), lay on the floor: linoleum or laminate.

The article examined the main key points of floor insulation with penofol in a wooden house. The video below shows this process clearly.

Compliance with the technology will increase the temperature in the room and significantly save on energy consumption.

Insulation disadvantages

Penofol has far fewer cons than pros. Its price is slightly higher than that of other heaters. Penofol is not always enough to retain heat; it is often necessary to use several materials at the same time.

The use of additional adhesive liquids will help to fix the material evenly during installation. They slightly increase the cost of the project.

Watch the video:

It is difficult to lay a foam foam heat-insulating coating on the floor yourself, because the slightest technological errors can be the basis for a strong decrease in the room air temperature. Before work, study in detail all the nuances of the project and take the task seriously.

How to choose the right material

can be carried out using a variety of materials, which are also often used for insulating walls and roofs.

Such materials are:

  • Mineral wool of various types (glass, stone, slag);
  • Ecowool, polyurethane foam insulation;
  • Polystyrene, penofol, isolon.

Materials known since ancient times can also be used: sawdust, polystyrene foam or expanded clay. Choosing a floor insulation should be based on humidity, the purpose of the room, as well as on personal tastes and financial capabilities. In a wooden house, the possibility of waterproofing and resistance to insects should be additionally noted.

Benefits of bottom insulation

From the point of view of labor costs, it is more profitable to insulate the floor from above. In this case, the insulating layer is mounted between the frame (logs) and the top finishing layer.

But in some situations, lower insulation is preferable.

This method of thermal insulation is most often used in private houses with an uninsulated basement, garage, in frame buildings on pile and pile-screw foundations.

  • the insulation layer is not subjected to loads from furniture standing on the floor and the movement of people around the house, therefore, heat-insulating material of any rigidity can be used;
  • the height of the room does not decrease;
  • not only the top flooring is protected from freezing, but also the entire floor frame, which reduces the likelihood of freezing and water ingress on the wood - this increases the service life wooden structures and ensure their reliability.

It is more expedient to insulate a house on stilts from below

Installation inside the house

From within wooden house insulation is used for thermal insulation of the following structures: walls, ceiling, floor, attic, basement or basement. Due to the non-permeation of moisture, it can be used in damp and dry rooms. Pe rules:

  1. With the foil side, penofol is laid to the side where the body should be reflected, that is, into the room.
  2. For better thermal insulation between the wall and the material, a ventilated gap of 1.5-2 cm is left. The same is done between the insulation and the outer wall finish.
  3. To achieve complete sealing, the seams are glued with a special foil construction tape.

wall insulation technology

Insulation of a wooden house from the inside with penofol is carried out according to the following scheme: a wall, a space of 1.2-2 cm from a crate, a heater, a crate, an exterior finish, such as GKL or GVL. More details of the scheme and design are presented in the video and photo in this article.

Work is being done in stages:

  1. Bars 15-20 mm thick pre-treated with an antiseptic are attached to the wall. Any step of the crate, but not more than 1 m.
  2. Penofol is attached to the crate. It is easier to do this with a stapler or small carnations. Laying is done end-to-end. They are sealed with foil tape.
  3. A counter crate from a beam of a smaller or the same section is attached to the material. The bars are attached in the opposite direction to the first crate.
  4. Any panels (block house, imitation of timber, lining) are attached to the crate from above, or sheet material(GKL or GVL).
  5. The walls are plastered and painted or covered with wallpaper.

It is not difficult to perform thermal insulation with your own hands. the main thing is to follow all the steps. Video and photo materials in this article will help even a beginner to cope with the work.

How to apply

The scope of isolon goes far beyond the boundaries of the construction industry: it is actively used in the manufacture of cars, refrigeration equipment, the medical industry, in plumbing needs, and even in the oil industry. He also found his application in the production of life jackets, sports equipment, packaging.

Most often, isolon is used for installing underfloor heating and balconies. There are technologies that allow the use of isolon in the insulation of external and internal walls, roofs, but the principle, as they say, is one. The only difference is that in cold, unheated rooms, which include a balcony, one isolon is not enough, then the technology of a sandwich made of cotton insulation or polystyrene foam and foil isolon is used. If the room is small, and you cannot give additional area for insulation, then you should increase the thickness of the isolon to at least 2 centimeters. Using the example of loggia insulation, we will show the principle by which you can insulate (with certain deviations depending on your conditions) any surface.

How to properly attach isolon is still known to very few, since the technology is quite new. Isolon on the walls is laid with foil inside to reflect heat. If you prefer a sandwich, then between the two layers of isolon a gasket is made of mineral or glass wool, polystyrene foam, polystyrene foam, a crate is mounted on top for decorative design materials, such as plastic panels, lining, etc. All seams are carefully glued with special reflective tape, tightness in the process of insulation is very important, so this advice should not be neglected.

In order to more clearly describe all the processes, a brief step-by-step instruction is given:

  1. Clean and dry the surface to which the attachment will be made.
  2. Measure the area, prepare the required amount of material.
  3. Lay out, attach the isolon to the surface with foil towards you.
  4. Glue all existing seams and attachment points with special adhesive tape.

Installation of isolon

The manufacturer gives several more ways to use isolon:

  • The use of sheets for hardening concrete - isolon prevents heat loss and rapid drying, therefore it is invaluable as a material for laying concrete.
  • Like bedding for artificial turf.
  • As separating partitions when pouring the foundation.
  • When isolating water supply, drainage, ventilation pipes.
  • As heat-reflecting screens (fixing the isolon to the wall behind the battery allows you to redirect warm air masses into the room, which prevents rapid cooling. According to statistics, energy savings in this case exceed 25%).

When and why wooden houses are insulated

A well-built wooden house does not need additional insulation.

Insulation of a wooden house from the outside

The problem is that to build the “right” house, you need the “right” logs, which in practice happens quite rarely. As a result, log cabins are often built from what they managed to buy, and after a few years they get uneven shrinkage, warped corners and the need to insulate the facade.

Separately, we note that due to the factors listed above, situations may arise when even repeated caulking will not help, and both external and internal thermal insulation will be needed to bring the house to normal energy performance.

The main method of additional thermal insulation is the installation of insulating structures outside the facade of the house.

Internal laying of penofol is used only in cases where it is necessary to create a special mode of operation of the building. For example, in baths and saunas, where such protective layer at the same time it plays the role of a heat insulator and hydroprotection, or in rooms for which an economical heating mode is defined (loggias, verandas, attics, etc.).

Wall insulation in the bath

Special mention deserves a trend towards higher energy prices, which is why many country cottages made of wood are built without the use of classical heating systems.

As a rule, such houses are designed only for the summer season. In order not to exclude the possibility of a winter visit, they are maximally insulated from the inside and infrared heating panels are installed.

Moreover, in Finland, which is famous for its energy-saving technologies, there are projects in which heating radiators are installed on the ceiling, under an insulating foam structure.

Materials used

Entering the store building materials, you can see how wide the range of products in question is. Each heat insulator differs in its size, characteristics and installation method. The choice of this or that material depends on the personal wishes of the owner and the characteristics of the flooring.

Mineral wool

For thermal insulation of a cold wooden floor, mineral wool is often used. The heat insulator is produced in the form of elastic mats and panels. The process of its installation is carried out in one layer.

Mineral wool insulation

The main advantages of the material include:

  • high noise and heat insulation performance;
  • long service life;
  • resistance to fire and high humidity;
  • acceptable cost;
  • security;
  • resistance to mechanical and chemical factors.

It may also be useful for you to learn about how the lumber house is insulated from the outside with polystyrene foam.

polyurethane foam

The material is ideal for thermal insulation of the floor from below. Its peculiarity is that it contains pores that are filled with air and gas. Polyurethane foam has a low weight, but at the same time it perfectly retains thermal energy. Possesses the maximum resistance to formation of a fungus, a mold. Resistant to rot and acids.

Insulation Polyurethane foam for the floor

Polyurethane foam is laid using a special technique, and it is also characterized by excellent adhesion to the surface. With the help of this material, it is possible to carry out floor insulation different shapes without forming joints. But how the front door is insulated with one's own hands with such material and what material can still be used to make insulation, is indicated here.

Styrofoam

This heat insulator for floor insulation from below is considered the most popular. Thanks to its special structure, low level vapor permeability and heat conductivity, resistance to fire. The material is also distinguished by reliability and resistance to the influence of mechanical and chemical factors.

Insulation foam for the floor

Polyfoam has a long service life, while it retains its heat-insulating ability. Its main disadvantage is that it absorbs a small amount of liquid, which adversely affects certain properties. But here is how the floor is insulated in a wooden house from below with foam, indicated here.

Penoplex

You can make the floor warmer in a wooden house with the help of penoplex. It is characterized by light weight and homogeneous polymer composition. Thanks to this, there is no load on the foundation of the house. The heat insulator is made by extrusion method - forcing soft raw materials through the molding recess of special equipment. And here in more detail how to make floor insulation with penaplex.

Insulation penoplex for the floor

The heat insulator is highly reliable, resistant to low temperatures. It will show its thermal insulation qualities for a long time and will create reliable protection against moisture penetration. But how to insulate the floor with penoplex in a wooden house, and how easy it is to do, is indicated here.

Expanded clay

Thermal insulation of a wooden floor can occur using expanded clay. This is a bulk material, which is characterized by a porous structure. A heat insulator is produced by firing slate or clay in a special furnace.

Expanded clay insulation for the floor

Expanded clay is a durable and environmentally friendly material. It is characterized by high rates of sound insulation, resistance to fire and frost. But expanded clay has one minus - after a while it becomes too dense due to its own weight and loses its heat-insulating qualities. But how the wet facade is insulated with a heater, this information will help to understand.

Penofol

This material for floor insulation is produced in the form of rolls. Received on the basis of polyethylene foam, which is covered with aluminum foil on top. The thickness of the material is 3-10 mm.

Penofol insulation for the floor

But despite this, he perfectly conducts thermal energy and does not need to lay auxiliary vapor barrier. But penofol has a number of disadvantages, including exposure to rust and loss of strength. It will also be useful for you to learn more about how

Izolon

This heat insulator today enjoys a wide scope due to its versatility. Isolon is an elastic type polyethylene foam that has a cellular structure, where each cell is of a closed type. It can be obtained in different densities and thicknesses, which once again confirms its versatility.

Floor insulation isolon

How thermal insulation is performed with isolon

Floor insulation in a house made of timber can be done in three ways. Below we will consider each option separately.

First way

Plates of extruded polystyrene foam are laid on the leveled ground, the seams between the sheets are foamed with mounting foam.

A concrete screed is made on top of the insulation. It is necessary that the concrete base be even, without cracks and other defects. If there are gaps, they must be puttied, and then sanded.

After cleaning the surface from dust, rolls of isolon are laid on it (the protective film must first be removed from the material), which are fixed to the floor with glue or dowels. Between themselves, the sheets are glued with foil tape.

Second way

The pre-leveled soil is covered with a waterproof membrane, then mineral wool slabs are placed on it. A waterproofing film is also laid on top. The lower hydromembrane protects the insulation from moisture coming from the ground, and the upper one does not allow it to enter the room.

Floor logs are installed on which boards are stuffed. Above them is thermal insulation of the floor. Isolon is spread over the insulated surface and fixed with a stapler or screwdriver. Joints are glued with adhesive tape with a foil layer. Then the floor covering is laid.

Floor insulation along the lags:

  1. Remove old flooring.
  2. Lay wooden logs on the rough base at a distance of 600-1000 mm from each other. Before laying the beams must undergo an antiseptic treatment against decay.
  3. Between the lags, boards or plywood sheets are laid on special cranial bars.
  4. A layer of waterproofing is laid on the prepared wooden base, and then sheets of insulation are spread out so that the upper edge of the material is lower than the lag in height. Izolon itself has vapor barrier properties, so there is no need to lay a vapor barrier film on top.
  5. A finishing flooring is laid on top of the heat insulator. For its arrangement, boards with a thickness of more than 3 cm or sheets of plywood are usually used, which are laid in a perpendicular direction with respect to the beams.
  6. A finishing floor covering is laid on top of the insulated base.

Roll material laying technology

Step 1. The material produced in a roll must be laid on a surface cleared of debris. The base is swept, washed if necessary and dried.

Foundation preparation

Step 2 The insulation is cut into segments of the required length and size.

Cutting foil insulation

Step 3 The material is leveled on the surface of the room.

Another photo of the process

Step 4 In small rooms, the insulation is attached along the walls and across with wooden bars. Its individual sheets are glued together with adhesive tape.

The insulation is attached with bars

The process of installing bars

Step 5 If the flooring allows (it is quite dense), then a crate is made over the laid insulation. This makes it possible to create an air gap.

Video - Laying the roll substrate

Insulation with a layer of foil - good option high quality insulating material. It will serve for many years, if you choose it correctly according to the operating conditions, as well as under correct styling. It is easy to avoid mistakes, the main thing is to carefully read all the nuances of using the material.

2 Specifications

The certificate of conformity of penofol indicates that the insulation with this material (type "A", thickness 4 mm) is similar in efficiency to the following products:

  • 46 mm foam outside the building;
  • 84 mm of mineral wool from the inside of the building;
  • 108 mm pine boards from the inside of the building;
  • 216 mm expanded clay outside the building;
  • 348 mm foam concrete blocks outside the building;
  • 672 mm additional brickwork outside the building;
  • 36mm PPE from inside the room.

The technical assessment of penofol, in accordance with the requirements of the FCS Gosstroy of the Russian Federation "TO No. 0457", determines whether this insulation has the following characteristics:

A layer of penofol located behind the battery increases the heating efficiency

2.1 Product reviews

So that you can get a complete picture of the rationality of using penofol as an insulating material, he invites you to study the reviews of people who have many years of experience in using this product.

Igor, 50 years old, Saratov:

A couple of years since I am the owner of a small suburban area, in the city, which I dreamed of for a very long time. As soon as the land was purchased, I immediately began building a wooden house, a sauna and a garage. I wanted to do everything in good conscience, so it was decided to insulate these buildings with high quality.

For thermal insulation of the bath, I preferred foil penofol, since the reflective properties of this material, small thickness and adequate cost make its use the most justified. The sellers immediately demanded a certificate of quality, as he had heard about a large number of fakes of this penofol.

Using this material, I performed the insulation of the walls, the roof, and also isolated the floor from the inside of the bath. Now, after one good heating, the high temperature in the bath lasts for two days. Very satisfied. I recommend!

Oleg, 30 years old, Murmansk:

I used foil penofol to insulate the walls from the inside of a brick house. I can’t say anything bad about the material, since only positive experience remained. At the old rate, I remember, it cost me mere pennies, while everything was as it should be - a quality certificate, a guarantee from the manufacturer, instructions for use, etc.

The insulation itself did not let us down, the minimum thickness, but at the same time, the efficiency is no worse than penoizol, with which I insulated the floor in the garage. In the near future, with the help of penofol without foil, I plan to insulate the floor under the laminate in the living room and bedrooms.

Peculiarities

Foil isolon is a heat-insulating material based on polyethylene foam. The thermotechnical indicator is achieved by applying a metallized polypropylene film to the material. It can cover the polyethylene layer on one or both sides.

Instead of a metallized film, polyethylene foam can be covered with a layer of polished aluminum foil - this does not affect the thermal insulation qualities of the product, but helps to increase its strength.

High thermal insulation performance is achieved through the use of a foil layer that reflects 97% of thermal energy, while the material itself does not heat up. The structure of polyethylene assumes the presence of the smallest air bubbles, which provide low thermal conductivity. Foil isolon functions on the principle of a thermos: maintains the set temperature range indoors, but does not heat up.

In addition, the material is characterized by high vapor permeability (0.031-0.04 mg / mchPa), which allows the surfaces to breathe. Thanks to the ability of isolon to pass moisture vapor, it is possible to maintain optimal air humidity in the room, avoiding dampness of walls, insulation, and finishing materials.

The moisture absorption of the insulation tends to zero, which guarantees the protection of surfaces from moisture penetration, as well as the formation of condensate inside the material.

In addition to high thermal efficiency, foil isolon demonstrates good sound insulation (up to 32 dB and above).

Another plus is the lightness of the material, combined with increased strength properties. Light weight allows you to mount the insulation on any surface, without requiring their preliminary reinforcement.

It is important to remember that plaster cannot be applied over isolon, wallpaper can not be glued. These and other finishing materials, fixed directly on the insulation, will pull it under their own weight.

Since the material is not designed for such loads, it will simply fall off. Finishing should be done only on a special crate.

Isolon is a non-rotting, environmentally friendly material that does not emit toxins during operation. Even when heated, it remains harmless. This greatly expands the scope of isolon, which can be used not only for exterior, but also for interior decoration of residential premises.

Along with environmental friendliness, it is worth highlighting the biostability of the product: its surface is not subject to the attack of microorganisms, the insulation is not covered with mold or fungus, does not become a home or food for rodents.

The metal film demonstrates chemical inertness, resistance to mechanical damage and atmospheric phenomena.

The material has a small thickness, so it is the most suitable material when it comes to internal thermal insulation. For materials of this type, not only technical indicators are important, but also the ability to save as much usable area as possible after insulation - foil isolon is among the few insulating materials that can cope with this task.

The disadvantage of the product is sometimes called a higher cost compared to other popular heaters. However, the difference in price is offset by the ease of laying the material (you can save on the purchase of vapor and waterproofing materials, the services of professionals), as well as the high thermal efficiency of foil isolon.

The calculations carried out prove that after its installation it is possible to reduce the cost of space heating by 30%. It is important that the service life of the material is at least 100 years.

Additional thermal insulation for floors

Scheme of laying penofol on the floor

Considering that penofol, in addition to thermal insulation, also has vapor barrier properties, it is actively used in the arrangement of floors. At the same time, the protective tape can be installed both from the side of the basement, and directly from the bottom of the floor.

To insulate the floor with penofol in a wooden house, two laying options are used:

  • with one-sided reflection towards the ground;
  • with double reflection.

The double-sided option is used on cold foundations, but in this case an air gap must be present on both sides of the insulating tape.

The company "Master Srubov" accepts orders for all types of work performed in the course of finishing log and lumber houses to the level of readiness for finishing, including work on external and internal thermal insulation of wooden log cabins. To clarify the details of cooperation, as well as find out the terms and cost of order fulfillment, go to the "Contacts" page and contact us in any way indicated there.

Wooden floor insulation

Scheme of wooden floor insulation.

Would need:

  • roll of isolon;
  • screwdriver;
  • construction stapler;
  • special glue;
  • foil tape;
  • bricks;
  • cement.

In a private house, under wooden boards, for better heat and vapor barrier, a dry and warm concrete floor is made. This can be done in several ways.

Firstly, extruded polystyrene foam must be laid on the previously leveled soil, filling the seams between the sheets with mounting foam. From above, the surface of which should be smooth, without cracks and flaws. If there are flaws on it, they need to be puttied and sanded. Then the surface is cleaned of dust and dirt.

After that, the floor is insulated with isolon. The rolled material, from which the protective film is removed, is spread on the floor, fixed to it either with special glue or with a screwdriver. The joints of the sheets are glued together with foil tape.

Secondly, to insulate the floor on the ground, you can lay mineral wool material, which is previously closed from the ground with a special membrane. This is necessary so that the moisture emanating from the ground does not fall on the insulation. From above, the heat-insulating material is again covered with a membrane so that moisture, in this case, does not enter from the room.

Floor insulation in a wooden house.

Then the logs are installed, on which the boards are stuffed. It is done on top of them. It is rolled out and attached to the surface either with a construction stapler or a screwdriver. Joints must be glued with foil tape. Laminate or parquet can be laid on it.

Thirdly, floor insulation can be carried out along the logs. To do this, the old coating is removed and draft floor fit wooden beams, pre-treated with a special solution from decay, at a distance of 60-100 cm from each other. Then, shields made of plywood or boards are fixed between the lags, which are fixed on special bars.

A rolled isolon is spread on the prepared flooring and fastened with a construction stapler or a screwdriver. A waterproofing layer must be laid on it. Since this thermal insulation material has vapor barrier properties, it is not necessary to lay an additional layer of vapor barrier. At the end, the floor is installed with wooden boards and its subsequent finishing with any floor covering.

Floor insulation, especially for rooms located on the first floors, can be done along the logs of brick columns. First with bricks and cement mortar columns are laid out on a strip of wood. Then, between the lags, you need to spread a layer of isolon, which is also the vapor barrier of the room. After that, a wooden floor is mounted on the logs, and the selected coating is mounted on it.

The use of mineral wool

Mineral wool rightfully bears the title of the most popular insulation. Cotton wool is slag, glass and stone. The most important advantage of this heater is its fire safety. Mineral wool is also famous for its resistance to chemical and biological destroyers, and also has good insulating performance.

Mineral wool.

Minuses of mineral wool can be called its low strength and poor vapor permeability. The material perfectly absorbs moisture from the air, losing its properties of a heat-insulating agent

That is why when using cotton wool, special attention is paid to isolation from steam. Mineral wool is not included in the list of materials safe for humans, so it must be used very carefully.

Cotton wool is produced in tiles or in the form of a plastic mat. The hard board is made from hydrophobized mineral wool and the harder side is indicated by a blue stripe. During installation, the hard side must be facing up. Solid floor insulation is mainly used for thermal insulation of the floor in a wooden house and is placed in one layer.

Rockwool also has good soundproofing properties.

Mineral wool-based floor heaters - Izovol and Rockwool - are also very popular. Izovol has a low thermal conductivity, and its hydrophobic properties are much higher than in ordinary cotton wool. Izovol is also a biologically, chemically and fire resistant material, which makes floor insulation in a wooden house an excellent opportunity to make a video about the process, everything is so simple and easy.

Rockwool - basalt insulation based on mineral wool. A distinctive feature of rockwool is its high resistance to physical stress, due to which the material does not deform during installation and operation. Due to the porous structure, Rockwool also perfectly absorbs sounds, so it can also be a soundproofing layer.

sawdust insulation

Floor insulation with sawdust is one of the most profitable ways of insulation.

The main advantages of sawdust as a type of insulation are:

  • Low cost (compared to other materials);
  • Ease of installation (sawdust is poured into the required place), thanks to which even the most inaccessible place can be insulated;
  • Ecological purity of the material, as a result of the wood origin of materials.

Insulation can be not only sawdust in its pure form, but also building materials that include them in their composition. Wood blocks - made from sawdust, blue vitriol and cement, such material is cheap and effective, but is more often used for wall insulation.

Wood blocks.

Sawdust granules (pellets) - a heater in the form of granules, which consists of sawdust, antiseptic and glue. Thanks to these components, the insulation not only stores heat well, but is also resistant to fire, sawdust concrete is a mixture of sand, sawdust, cement and water. In terms of thermal conductivity, it is comparable to slag concrete, but more environmentally friendly. The presence of sawdust in the composition requires good waterproofing before installing sawdust concrete.

Arbolit - cement mixed with organic aggregates ( wood chips) and chemical impurities. Arbolite slabs have high rates of noise and heat insulation, and are also fire resistant, easy to process and bend.

Before using wood concrete, it will be useful to check the waterproofing, because the plates made of this material are very unstable to moisture. Despite the abundance of materials from sawdust, floor insulation is most often made with sawdust in its pure form, especially in a wooden house.

Varieties of foil insulation

Traditionally, isolon is sold in the form of rolls, however, the thickest varieties of insulation (usually 15 mm) can also be produced in the form of sheets that have a standardized size.

Insulation based on foamed polyethylene is represented by three main varieties:

  • with one-sided foiling;
  • double sided foil. Such heaters are used if it is necessary to further enhance the thermal insulation performance;
  • with one-sided foiling and a self-adhesive layer on the other side. Adhesive base covered protective film. Typically, this material is used to insulate various kinds of vertical and inclined surfaces. Thanks to the self-adhesive layer, the process of performing heat-insulating work becomes as convenient and fast as possible.

Also considered heaters are classified depending on the properties source material. So, budget varieties are most often produced on the basis of ordinary polyethylene. The material is repeatedly foamed during production. As a result, a closed porous gas-filled structure is created. Such heaters have 2 main drawbacks: a tendency to shrink and low resistance to deformation loads.

More attractive in terms of performance characteristics is a heat-insulating material made from the so-called. cross-linked polyethylene. Such a heater has a much higher density, better tolerates mechanical loads and tends to restore its original shape after the cessation of dynamic influences.

The technology of insulating the ceilings of a wooden house with isolon

The impressive properties of the material in question make it possible to use it in the production of works when the ceiling is insulated with isolon in a wooden house. In this case, it usually complements mineral wool. The material application technology is as follows:

  • First, mineral wool is laid between the ceiling lags;
  • Then the isolon is attached to the logs with a stapler, glue or dowels, and the material must be positioned so that it is in a slightly taut position;
  • A control crate is made directly along the insulation, which is also fixed to the logs;
  • At the final stage, a decorative ceiling covering is performed.

The use of isolon as an independent insulation or in combination with other heat-insulating materials can seriously increase the energy efficiency of a wooden building. In addition, the additional reflective properties of the foil coating make this insulation method even more attractive to private developers. An important argument in favor of the material is its reasonable cost, which is also among the most important reason his popularity.

Using penofol on concrete floors

Floor insulation in a private house with penofol is widely used even on a concrete base.

To make it work quality coating, it is necessary to perform the work sequentially:

  1. The concrete pavement is being leveled. It must be free of all kinds of contaminants. It is better to use Some prefer self-levelling compound.
  2. Penofol is placed on the resulting flat surface. It is recommended to choose class "B", where there is a foil on each side. It is necessary to make high-quality joints, and then close them with aluminum tape.
  3. The next step in insulating the floor with penofol will be the installation of a wooden frame. The cross section of the timber used must be at least 5.5 centimeters
  4. A heater is selected, which is placed in wooden frame. It must be pressed with mineral wool. It is possible to use foam.
  5. Next, the second layer of penofol is laid. For this stage, you can take class "A" of the desired product, which has foil on only one side.
  6. The final stage of insulation will be the installation of boards that are laid on wooden logs from above.

Features of use

The use of floor insulation allows you to increase the insulation characteristics of structures without increasing the height and thickness. It can be used on its own or in combination with other types. In each case, it is necessary to consider the feasibility of laying, based on the tasks of the technology. When mounted on a wooden floor, a noticeable thermal effect is obtained. Surface heats up quickly, saves energy long time, without additional thick layers.

Interfloor ceilings are classified as the most susceptible to extraneous sounds and cold penetration. The best way to eliminate the shortcomings is to insulate with foil Izolon. It reliably protects engineering systems, ventilation, pipe and gas pipeline. For such work, it is recommended to use a foil stamp. Self-adhesive film is easily placed on a metal surface, holds securely and provides high-quality insulation and noise isolation of the carrier. Isolon is suitable for floor insulation during the operation of electrical and water structures. Effectively functions under the coating of laminate, parquet, linoleum, carpet.

Installation nuances

Izolon laying scheme is performed in different ways, depending on the base, and according to the instructions:

1. Insulation for a wooden floor.

Under the structure of the boards make a concrete screed. Extruded polystyrene foam is placed on the pre-cleaned surface, then the solution is poured. The base must be free of cracks and defects. If they formed after the mixture hardened, it is necessary to treat with putty and sand. After that, the plane is cleaned, the thermal insulation of the floor is carried out using Izolon. The protective film is removed from the roll, rolled out and fixed with adhesive or fasteners. Joints are sealed with foil tape.

When using mineral wool as a heater, it is better to plan the construction of a lag. The formation is covered with a special membrane on both sides to prevent moisture from entering from the soil and the room. They start laying wooden beams, on which boards are placed, then Isolon. The sheets are connected to the logs with a stapler, the top coat is mounted on top.

If the crate was installed earlier, beams are placed on the rough base, then plywood panels. Insulation is rolled out on the finished flooring, on top - a layer of waterproofing.

2. Concrete floor insulation.

The main drawback of such grounds is that they always pull cold if you do not take action. The scheme is similar to the technology in a wooden house, but it should be noted that the construction of a lag in an apartment is accompanied by a decrease in area by 10 cm, so you should follow the guide. A moisture-proof membrane must be placed on the screed. The distance between the bars is 50 cm, Isolon is laid in between.

If floor insulation is carried out directly on the concrete surface, it is important to ensure that there are no cracks and irregularities. Mounted on a clean and dry screed with glue

To reduce energy losses, the joints of the rolls are sealed with tape. According to Izolon's instructions for use, it is not recommended to use soft topcoats. For carpet and linoleum, you will have to equip an additional solid layer of plywood. When installing water systems, the construction of a crate is required, on which insulation is laid. It is fixed to the frame with a stapler, the attachment points are glued with foil tape or construction tape.

Of all modern materials, Isolon is the most effective as a floor insulation, due to the peculiarities of production. Grades without a metallized component are designed more to absorb noise and protect against condensation; they are often used as a substrate for laminate and parquet. Foil Isolon is an excellent protection against heat loss, provides reflection of energy into the room, comfortable living.

Water floor insulation

Scheme of water floor insulation.

You will need:

Many owners of private houses use plastic heating pipes as floor insulation, which are laid under the finishing floor. When performing its device, it is necessary to strictly follow all the rules. And as a result, you will get a quality work done with your own hands.

First, the logs are installed, on which the crate is made. On it you need to roll out a vapor barrier layer, which is used as isolon. It is attached to the logs with a construction stapler, and the attachment points are glued with waterproofing tape.

Further, a layer of thermal insulation from mineral mats is mounted between the lags of the subfloor. Its thickness must be at least 50 mm. Then an isolon with a foil base is laid out and fixed to the logs with a construction stapler. After that, a pipe is installed, which is a heat carrier. To prevent heat loss, in places of cold zones, the pipe should be insulated. At the end, the floor is mounted with boards and the floor covering is laid.

Penofol in isolation

Penofol - pretty new material in the insulation market, and therefore has not yet gained popularity. Penofol is a rolled material having several layers, consisting of a heater and a reflective layer (foil). Any material can be used as an insulating layer, but it is preferable to use light-transmitting materials (polyethylene foam).

The classic Penofol, which was invented by the Russians, is a polyethylene foam that is thermally bonded to the foil. But this option is not suitable for all the nuances of construction, so now you can find a large number of varieties of penofol. As an insulating layer, different floor heaters can be used, which allows you to get an improved version of Penofol.

The classic version of Penofol has a high density, therefore it is suitable for insulating the floors of a wooden house with a high level of load. The insulation is universal, and can be used for the main heat, hydro and vapor barrier, as well as an auxiliary insulating layer.

Penofol can also have both one- and two-sided foiling. Penofol-2000, which can be found on the market in one- and two-sided versions, repeats the classic version of Penofol in everything, but at the same time it is cheaper.

There is also Penofol type C, which means self-adhesive. This insulation has several layers: sewn polyethylene foam, on one side of which aluminum foil is welded, and on the other side, waterproof glue with an anti-adhesive coating is applied. Thanks to the adhesive, the insulation is easily attached to almost any surface, which makes it a great way to insulate the floor in a wooden house.

Gluing joints.

Due to the small thickness and foil, the installation of Penofol is easy and fairly fast. The material is placed on the floor surface with an overlap or end-to-end, and the resulting joints are glued with metallized adhesive tape. When using Penofol, you can forget about the presence of hydro and vapor barrier, since this function is performed by foil.

Use of polystyrene

Expanded polystyrene (polystyrene) is also among the leaders in thermal insulation. Such popularity is due to the huge number of pluses and a minimum of minuses.

Polyfoam has low heat-conducting qualities and is practically vapor-tight, durable and fire-resistant. Styrofoam never molds and does not attract rodents. The cellular structure extends the life of the foam and makes it more effective as a heat-insulating material.

Among the shortcomings of the foam, high moisture absorption can be noted, so attention should be paid to the organization of vapor and waterproofing. .

Alternative materials

There is no alternative to isolone, as such, but we will be wrong if we do not briefly talk about materials that can replace it in one way or another.

cotton wool

Practically the same as isolon, cotton materials, which include mineral, glass and ecowool, have. Their manufacturers insist that their main advantages are:

  • Ease and simplicity in installation.
  • Low thermal conductivity.
  • Strength under compression, mechanical stress, tearing.
  • High soundproofing characteristics.
  • Not susceptible to fire.
  • Resistance to temperature deformation.
  • Biological and chemical resistance.

Use in mineral wool insulation

Mineral wool is produced in the form of rolls and sheets, have different softness and thickness. Mount structures using various kinds wool is extremely simple:

  1. The walls must be closed with a steam or hydro barrier using a stapler.
  2. The next step is to assemble the frame from special metal profiles, the assembly step is 50 centimeters.
  3. Then cotton wool is laid, carefully distributed throughout the space, avoiding gaps.
  4. Then the cotton wool is fixed in any convenient way, the structure is closed with drywall sheets, plastic panels, clapboard, fiberboard.
  5. The final stage is the decoration of the walls, its appearance depends on what material you have chosen or is available.

The disadvantage of the material is its allergenicity, it is necessary to work in protective gloves and a mask in order to prevent contact of the material with the mucous membranes and skin of the hands. It also requires additional vapor barrier, since it loses its properties from moisture. In principle, the technology is simple and you can easily do everything yourself, without overpaying contractors.

Polyfoam or its analogues

The undoubted advantages of polystyrene include the fact that:

  1. Polyfoam is not afraid of moisture.
  2. It is a good thermal insulator.
  3. It is not subject to rotting, the formation of fungal or mold spots.
  4. Easy to install and cut.
  5. Has a low weight.
  6. Heat resistant to low temperatures.
  7. Does not require waterproofing.

foamed foam

The disadvantages of polystyrene are also many:

  1. Fragile, crumbling, requires additional protection with a dense base.
  2. Doesn't breathe.
  3. Easily destroyed, enters into chemical reactions.
  4. We love rodents.

Polyfoam is used mainly in non-residential premises or for outdoor use. Installation is carried out on an adhesive mixture, it requires additional fixing with “fungi”, careful lubrication of the seams, plaster and subsequent painting.

Cork

The advantages of cork coatings, of course, include:

  • Remarkable isolation of extraneous noise and provision of heat saving.
  • waterproof properties.
  • Resistant to deformation and pressure.
  • Fire safety.
  • Opposition to the formation of fungus and mold.
  • Hypoallergenic.
  • Small degree of pollution.
  • A wide range, presented in slabs, rolls, mixtures.

There are no materials without minuses, the cork has:

  1. High material cost.
  2. Low durability of the protective coating.
  3. The manifestation of traces from heavy equipment or furniture.

The cork is mounted on glue - acrylic or contact, either with one-sided or two-sided application. The work is painstaking, requires endurance and attention, but it is quite possible to do it yourself. Installation requires special temperature regime and the humidity level of the wall - the temperature is not lower than 18 degrees, the humidity is not more than 3%. When gluing, air bubbles between the wall and the material should be avoided. Before starting work, the material must stand in the room for at least 24 hours.

As we can see, there is no material that would be equally versatile and technically suitable in various ways. From this follows the conclusion that modern material- isolon will find application in any home and for any needs. Wall insulation from the inside with isolon is the most rational solution. Use the new products with pleasure and provide yourself with increased comfort without spending fabulous sums on it!

How does a heater work

Heat is transferred by means of infrared rays, invisible to the human eye, but at the same time capable of heating opaque objects. In addition, this radiation can also be reflected from mirror surfaces.

Insulation brand "Izolon" is based on this principle. Being located between two walls, or between trim and outer wall, isolon reflects infrared rays back into the room, dramatically reducing heat loss, which means increasing the efficiency of heating systems and reducing the cost of maintaining the desired temperature in the room.

What is isolon

Isolon is a universal insulating agent made of flexible polyethylene foam that provides all types of insulation. The widest range of isolon is presented in:

  1. A material treated with an electric discharge and capable of being wetted by adhesives and paints.
  2. Foil-laminated rolls.
  3. Rigid and heat resistant sheets.
  4. Multicolored.
  5. With a reduced level of flammability.

Insulating material - isolon

All these are various subspecies of amazing material, but they all have:

  • The unique thermal insulation property of a thin material (1 cm), which can be replaced with 5 centimeters of wood or mineral wool, 150 millimeters of brickwork, 12 millimeters of polystyrene foam.
  • Effective protection against steam and moisture, due to the closed cell structure. Water is not absorbed by the material.
  • Excellent sound and shock isolation.
  • Softness, elasticity, light weight (except for hard tile samples).
  • Durability, resistance to rotting, low level of flammability, which provides it with a warranty period of up to 90 years
  • Chemical stability that allows it to be combined with all known materials.
  • Environmental safety, since the material does not have a strong odor, does not emit toxins either when heated or at rest. The materials from which isolon is made do not harm nature, even contact with food is allowed, so the insulation of walls with isolon inside is completely safe.
  • Versatility and ease of installation. This material is great for floors, walls, both internal and external. outside, roofs in residential and commercial premises. Installation can be carried out by anyone, even without building skills.

Isolon also differs in production technology into non-crosslinked and crosslinked. If we talk about the first variety, then this is just foamed polyethylene, in the structure of which a small number of chemical bonds, in the second, the molecules are crosslinked together, thus, the structure is modified, which makes it possible to achieve advanced level thermal insulation, resistance to temperature changes and the effects of organic solvents.

Properties of foil heat insulator

A good insulation with a layer of foil has not only heat-insulating properties. It is distinguished by high rates of sound insulation, is not afraid of temperature changes, protects the room from moisture penetration, and has vapor barrier properties.

On a note! A heat insulator with a foil layer is in most cases an environmentally friendly material; it does not harm either human health or the environment. It can be safely used in children's rooms, as it is non-toxic.

Foil insulation, especially from the category of materials made from foam or expanded polystyrene, is resistant to mechanical stress - even heavy furniture can be placed on the floor under which such material is laid. The insulation will not lose its properties even in this case.

It is especially important to use foil insulation when installing underfloor heating. It will minimize heat loss, due to which it will be warmer in the room, and the cost of paying utility bills will be significantly reduced.

The working insulation layer itself does not allow cold air from outside to enter the apartment, and the foil will ensure the preservation of heat inside it.

Installation of penofol inside the house

At the same time, the installation of foil insulation is very simple and it does not matter if it is supplied in rolls or plates. The material is easy to process - in order to cut a piece of a suitable size, you do not need to purchase any sophisticated equipment. It is enough to have any cutting tool with you.

Attention! If no insulation was used during the installation of the floor covering or underfloor heating system, this is considered a gross mistake and a violation of the material laying technology. .

Characteristics and benefits of isolon

The material has the following properties:

  1. High reflectivity. Due to this, heat loss in the room is significantly reduced.
  2. Waterproof. The insulation does not absorb moisture at all, which ensures its long operation without loss of heat-insulating properties. This characteristic is especially important when laying in wooden houses.
  3. It has a small thickness - from 2 to 15 mm, does not carry additional load on the structural elements of the log house. Great for floor insulation in rooms with low ceilings saving usable room space. Despite the small thickness, its thermal insulation qualities are comparable to those of a brick wall.
  4. Environmental Safety. The material does not contain or emit harmful components, so it is completely harmless to humans, and it can be used in any premises.
  5. It has a long service life, retains its properties at temperatures from -80 to +120 degrees.
  6. It is steady against influence of biological factors, is not subject to decomposition and rotting.
  7. It has good soundproofing characteristics.

The material is produced in the form of rolls or sheets of standard sizes.

Those who are interested in whether it is possible to insulate the floor with isolon should give an unequivocal answer: “Yes”, since the material goes well with wood and is the best choice for thermal insulation of the floor in houses made of logs and timber. Isolon is also great for insulating the ceiling, walls and other structural elements from inside the house.

It should be noted that this material is not recommended to insulate a bath, sauna and other rooms with high humidity.

Types and characteristics

The properties of foil insulation may vary. It all depends on the material that acts as the base layer.

Expanded polystyrene is a heater produced in the form of sheets. His characteristic features are:

  • large thickness;
  • significant volume.

On one side is a layer of foil. Its production is a rather complicated process, during which the granules of the material are fused together. This insulation has high strength characteristics. Foil polystyrene is not subject to decay processes, is resistant to fungus, and is not afraid of mold.

It does not lose its high characteristics even at high temperatures, therefore it can be used in the range from -100 to +180°C. Thermal insulation with polystyrene-based floor foil is the best option for residential premises. It is most in demand in buildings with a high level of humidity.

Foamed polyethylene is a thin coating that can have a thin metal layer on one or both sides. When carrying out work, the thickness of the foil insulation is of great importance, since this parameter varies from 2 to 10 mm.

His the main task- floor and wall insulation. Also, the material can be used for insulation of sewers and ventilation shafts. It is easy to install and is light in weight. Often, models of metallized polyethylene have an adhesive layer on one side. This greatly simplifies the installation process.

Mineral wool is familiar to many consumers. Its foil variety comes in the form of rolls or plates. Main use material associated with thermal insulation:

  • roofs;
  • floors in baths and loggias.

The peculiarity of the material is that the metallized layer of aluminum foil is present only on one of its sides. Its thickness varies from 5 to 10 cm. The basis of the insulation is fiberglass.

Basalt wool is resistant to the main factors external environment. Often it is used in the construction of gas stations. This choice is due to the fact that the material is non-combustible and easily withstands temperature extremes from -200 to +700°C.

Even in extreme conditions the use of this material does not lead to a decrease in its basic characteristics. Often it is used in the arrangement of furnace equipment and fireplaces. Insulation allows you to provide high-quality insulation of walls and roofs.

It should be noted that penofol insulation of private houses and apartments is becoming more and more popular for various reasons. There is also a lot of talk around this relatively new insulation, including its unique properties and ease of use. To understand what it is - penofol, as well as to find out the whole truth about its characteristics - this is the purpose of this article. In addition, we will talk about how it is better to insulate walls and other structures from the inside of the house with this material.

What is penofol

The material belongs to a new generation of ultra-thin polymer insulation, manufactured using foaming technology. In this case, we are dealing with polyethylene foam welded to a layer of reflective aluminum foil.

Thanks to the manufacturing technology, the small pores inside the foam foam have a closed structure, which is why the insulation practically does not let water vapor through. According to the manufacturers, the foil layer is designed to reflect infrared heat flows coming from inside the premises.

There are 3 main types of penofol:

  • with one layer of heat-reflecting foil (type A);
  • the foil is welded to the insulation on both sides (type B);
  • foil on one side, adhesive layer on the other (type C).

Note. One of the latest innovations is one-sided (type A) perforated foam. Many tiny holes are made in the insulation so that it becomes vapor-permeable.

The scope of penofol is thermal insulation from the inside of houses and apartments, including balconies and loggias, as well as any industrial premises. The insulation is offered in thicknesses of 3, 4, 5, 8 and 10 mm. To finally understand all the properties of the material, we suggest that you familiarize yourself with its technical characteristics presented in the table:


How to insulate with penofol

It should be noted that it is really very simple to insulate anything (wall, ceiling or roof) with penofol. If you follow the manufacturer's instructions, then in order to achieve maximum efficiency, it is necessary to provide an air gap from 1.5 to 2 cm wide on both sides. To create such a gap, rolled foam will have to be mounted on planks of wooden crates attached to the base.


That is, first you need to take strips 20 mm thick and attach them to the wall vertically or horizontally with an interval equal to the width of the foam roll. If the house is wooden, then the planks are mounted on self-tapping screws; dowels are required for brick or concrete bases. Then strips of the required length are cut off from the roll and shot at the slats with brackets from a construction stapler.


Important. Unlike various thin films, the installation of penofol sheets is not overlapped, but end-to-end. In this case, the foil side should be facing the inside of the room, and the joints must be carefully glued with aluminum tape.

When the foam insulation layer is fixed and glued with adhesive tape, the same strips are installed on top of it with their own hands to provide an external air gap. They are fastened with self-tapping screws to the previous crate, and are lined on the outside drywall sheets or use other finishing methods. Note that a vapor barrier film is not laid, since it is not needed, the penofol itself is a vapor barrier.



It cannot be said that in practice few people follow the instructions, usually penofol is attached directly to the wall or ceiling, and the air gap is made only on one side. This reduces the thermal insulation properties of the material, and below we will explain why. When insulating the roof or sloping walls of the attic, the installation of penofol is carried out by attaching rafters to the lower planes. This means that the space between the rafters is filled with another insulation, since one thin polyethylene will not be enough.


Important. If penofol is able to replace vapor barrier, then waterproofing - in no case. You can not lay it in the under-roof space in front of mineral wool, a diffusion membrane is needed there. It does not let water through, but does not prevent the passage of vapors coming out of the cotton wool.

Also, foamed polyethylene insulates floors in wooden houses, laying it between the logs. Again, first waterproofing is laid, then slab insulation, and on top - penofol. It is pointless to put it under the very bottom or in a screed; from compression, the material ceases to be heat-insulating. Although in practice, such errors can often be found.



Another area of ​​​​application of penofol is the insulation of balconies and loggias, where the material is laid in a second layer after more serious heaters - extruded polystyrene foam or polystyrene. The installation method is still the same: first, the crate bars are placed, polystyrene plates are laid between them, and foamed polyethylene is attached on top. After that, interior decoration is carried out.

Note. Perforated penofol is used as a heater for the walls of a wooden house in cases where it is necessary to ensure the vapor permeability of the structure.

The benefits of penofol - debunking myths

Manufacturers and sellers of penofol attribute wonderful thermal insulation characteristics to this insulation, which is actually a myth.

Also, misleading the buyer can be considered wiring diagrams with air layers, one of which we described at the beginning of the previous section. How the manufacturer proposes to insulate floors and roofs is shown in the figures:



In fact, the presented schemes are nothing more than another way to improve the thermal insulation of external fences with the help of air gaps, since the penofol is categorically lacking its own resistance to heat transfer.



This is easy to check by taking as a basis the best thermal conductivity from the table of technical characteristics, - 0.037 W / m2 °C. Next, we take the canonical formula and determine the thermal resistance of a material 4 mm thick:

R = δ / λ, where:

  • δ is the thickness of the penofol in meters, taken 0.004 m;
  • λ is the coefficient of its thermal conductivity, equal to 0.037 W/m2 °C.

We get R = 0.004 / 0.037 = 0.11 m2 °C/W. Now we look at the comparative table, which is presented on the same resource as the technical data. It says that 4 mm foam foam can easily replace mineral wool 77 mm thick or 46 mm polystyrene foam.



So, for comparison, it is necessary to determine the thermal resistance of a mineral wool layer of 77 mm (its thermal conductivity is 0.05 W / m2 °C):

Rminwool = 0.077 / 0.05 = 1.54 m2 °C / W, which is 10 times more than that of polyethylene foam.

Hence the conclusion: the presented comparative table is a pure fake. The data given in it are unreliable, and although the material is a good insulation, it is not better than others. The reason is that it is too thin, although it is equal in thermal conductivity to extruded polystyrene foam.

Against this background, all other advantages of penofol fade. True, there is another myth - about reflection infrared heat back inside the room thanks to the foil surface. But none of the manufacturers explains what the foil will reflect, being behind the interior trim. After all, infrared radiation spreads through open space, it will not pass through drywall or other barrier.



What penofol is really good for is its low cost and the ability to act as a vapor barrier along with other insulation, as evidenced by the reviews on the forums. In addition, it is easy to mount, the process does not take much time. You can also note the durability of the insulation, reaching 50 years, provided that it is located inside the building, and not outside. By the way, it is better not to use penofol for external wall insulation, there it will be of little use. You should not take it for the thermal insulation of the bath, like any polymer, when heated to 100 ° C, the material will emit harmful substances.

Conclusion

If you use penofol wisely and include insulation in the “pie” together with other materials, you can get an excellent result. As a rule, the thickness of the insulation is calculated to a minimum, and an additional layer of a thin and effective insulator will provide the necessary margin of safety, which may not be enough during a severe cold snap. Foil also perfectly reflects moisture, keeping the entire “pie” dry and providing a long service life.

No matter what material the house is built from, it is possible to create comfortable living conditions only if thermal insulation work is carried out. Only in this way the house will be warm and cozy. If you decide to take on floor insulation from below, then today it will not be difficult to do this if you choose the right heat-insulating material, and also do all the work strictly according to plan.

Warming work is carried out as follows:

  1. A frame is formed to provide a ventilation gap. For this, rails or a metal profile 20 mm thick are used.
  2. Penofol with a foil layer is laid on the frame and fixed with glue or a construction stapler.
  3. The gaps between the elements of the heat-insulating coating are filled with mounting foam or silicone sealant. Joints are glued with aluminum tape.
  4. A frame is fixed on top of the insulation, similar to the first one - decorative decoration of the room will be installed on it.

Tip: if the penofol is damaged during the installation process, you can repair it yourself by simply gluing the defects with aluminum tape.

A special case of insulation with penofol is the decoration of the balcony. It is somewhat more complicated, since it should be more efficient due to the smaller thickness of the walls. In essence, the technology is the same, only an additional layer of foam or foam must be installed between the wall and the insulation, which is fixed with plastic dowels.

External wall insulation

Insulation with foam foil with a foil layer on the outside is somewhat more difficult to implement. The technology differs in that an additional layer is required to protect against wind and moisture.

  1. A frame is mounted on the wall cleared of decoration.
  2. Penofol is fixed on the frame.
  3. A wind protection made of a special two-layer membrane is fixed on top of the insulation.
  4. A second frame for ventilation is installed.
  5. The facade is sheathed with decorative material.

Thus, penofol is a very effective insulation that can be used in a variety of situations without compromising performance. At the same time, do-it-yourself insulation with penofol is carried out without difficulty even by an inexperienced person.

The floor is rightfully considered one of the coldest parts of the house. This is especially true for apartments on the first floors and private houses. As you know, warm air tends to rise, while cold air tends to descend, moreover, drafts often make their way from under the floor covering. Heat loss can be prevented by insulating floors in wooden houses. The warming procedure is especially useful if the house has wooden floors. Over time, the boards, whatever they are, begin to dry out, cold air blows out of the resulting cracks. Such an omission can lead to the loss of 30% of all heat in the house, as a result of which the question arises - how to insulate the floor in a wooden house?

Insulation of floors in a wooden house is carried out according to a fairly simple technology, and in the process of thermal insulation, various heaters are used, the choice of which depends on certain circumstances.

Preparatory work

Before starting the insulation of floors in a wooden house, it is necessary to determine some parameters. So, we need information about the temperature and humidity in the room, as well as calculations of future loads on the floor and, in general, the purpose of the room. You will also need to approximately calculate the height of the thermal insulation layer and the entire structure.

Insulating the floor with your own hands is quite simple, the technology is quite easy and does not require a large investment of time. Thermal insulation of the floor is divided into the following layers: thermal insulation itself - vapor barrier - floor covering. The floor is insulated in a certain order, familiar in a wooden house.

First, wooden logs are laid. At the bottom of the log, boards or shields made of wood are fixed, these components will play the role of an additional base on which the insulation will be laid out. A heater is placed between the lags.

The material should be laid close, and possible gaps between the lags and layers of insulation should be sealed with foam or sealant. A layer of vapor barrier is placed on the laid out layer of insulation in the same way.

It is attached directly to the lags, and the joints and gaps can be glued with metallized tape.

The last step will be the installation of wooden flooring with subsequent finishing. When planning thermal insulation, it is necessary to first determine the required thickness, which is selected according to climatic conditions, as well as the type of insulation.

How to choose the right material

Wooden floors can be insulated with a variety of materials, which are also often used for insulating walls and roofs.

Such materials are:

  • Mineral wool of various types (glass, stone, slag);
  • Ecowool, polyurethane foam insulation;
  • Polystyrene, penofol, isolon.

Materials known since ancient times can also be used: sawdust, polystyrene foam or expanded clay. Choosing a floor insulation should be based on humidity, the purpose of the room, as well as on personal tastes and financial capabilities. In a wooden house, the possibility of waterproofing and resistance to insects should be additionally noted.

Wood insulation along the lags

Most often, for the thermal insulation of a wooden floor, the method of insulation along the logs is used. It is quite simple, but at the same time effective, as it allows you to avoid large heat losses. This method is most relevant when insulating a floor located close to the ground.

The technology is produced in stages. First of all, we install logs made of wood with a T-shaped cut into a log house, or put them on the foundation, observing a step from 0.6 to 1 meter. We fasten boards or wooden shields under the lags - insulation will be placed on them. Next, we lay hydro and vapor barrier, but only in the case of using a certain insulation (mineral or ecowool).


Vapor barrier sheets are laid with an overlap of 100-150 mm, and the edges must be bent to a height of up to 100 mm. Both special materials and ordinary polyethylene film can become a vapor barrier. At the end, we install the floor boards and finish the coating.

You can insulate the floor in a wooden house with the help of logs placed on brick columns. Logs are mounted on a brick pole through a wooden layer. A floor insulation is placed between the lags, which is immediately protected by a vapor barrier material.

The main argument when choosing thermal insulation in a wooden house along the logs is the simplicity of this method, as well as its high efficiency.

Using this insulation method, we do not subject the insulation to mechanical stress, so any heat-insulating structure is suitable as a material.

sawdust insulation

Floor insulation with sawdust is one of the most profitable ways of insulation.

The main advantages of sawdust as a type of insulation are:

  • Low cost (compared to other materials);
  • Ease of installation (sawdust is poured into the required place), thanks to which even the most inaccessible place can be insulated;
  • Ecological purity of the material, as a result of the wood origin of materials.

Insulation can be not only sawdust in its pure form, but also building materials that include them in their composition. Wood blocks - made from sawdust, blue vitriol and cement, this material is cheap and effective, but is more often used for wall insulation.


Wood blocks.

Sawdust granules (pellets) - insulation in the form of granules, which consists of sawdust, antiseptic and glue. Thanks to these components, the insulation not only stores heat well, but is also resistant to fire, sawdust concrete is a mixture of sand, sawdust, cement and water. In terms of thermal conductivity, it is comparable to slag concrete, but more environmentally friendly. The presence of sawdust in the composition requires good waterproofing before installing sawdust concrete.

Arbolit - cement mixed with organic aggregates (wood chips) and chemical impurities. Arbolite slabs have high rates of noise and heat insulation, and are also fire resistant, easy to process and bend.

Before using wood concrete, it will be useful to check the waterproofing, because the plates made of this material are very unstable to moisture. Despite the abundance of materials from sawdust, floor insulation is most often made with sawdust in its pure form, especially in a wooden house.

The use of mineral wool

Mineral wool rightfully bears the title of the most popular insulation. Cotton wool is slag, glass and stone. The most important advantage of this heater is its fire safety. Mineral wool is also famous for its resistance to chemical and biological destroyers, and also has good insulating performance.


Mineral wool.

Minuses of mineral wool can be called its low strength and poor vapor permeability. The material perfectly absorbs moisture from the air, losing its properties of a heat-insulating agent. That is why when using cotton wool, special attention is paid to isolation from steam. Mineral wool is not included in the list of materials safe for humans, so it must be used very carefully.

Cotton wool is produced in tiles or in the form of a plastic mat. The hard board is made from hydrophobized mineral wool and the harder side is indicated by a blue stripe. During installation, the hard side must be facing up. Solid floor insulation is mainly used for thermal insulation of the floor in a wooden house and is placed in one layer.



Rockwool also has good soundproofing properties.

Mineral wool-based floor heaters - Izovol and Rockwool - are also very popular. Izovol has a low thermal conductivity, and its hydrophobic properties are much higher than in ordinary cotton wool. Izovol is also a biologically, chemically and fire resistant material, which makes floor insulation in a wooden house an excellent opportunity to make a video about the process, everything is so simple and easy.

Rockwool - basalt insulation based on mineral wool. A distinctive feature of rockwool is its high resistance to physical stress, due to which the material does not deform during installation and operation. Due to the porous structure, Rockwool also perfectly absorbs sounds, so it can also be a soundproofing layer.

Penofol in isolation

Penofol is a fairly new material on the insulation market, and therefore has not yet gained popularity. Penofol is a rolled material having several layers, consisting of a heater and a reflective layer (foil). Any material can be used as an insulating layer, but it is preferable to use light-transmitting materials (polyethylene foam).

The classic Penofol, which was invented by the Russians, is a polyethylene foam that is thermally bonded to the foil. But this option is not suitable for all the nuances of construction, so now you can find a large number of varieties of penofol. As an insulating layer, different floor heaters can be used, which allows you to get an improved version of Penofol.

The classic version of Penofol has a high density, therefore it is suitable for insulating the floors of a wooden house with a high level of load. The insulation is universal, and can be used for the main heat, hydro and vapor barrier, as well as an auxiliary insulating layer.

Penofol can also have both one- and two-sided foiling. Penofol-2000, which can be found on the market in one- and two-sided versions, repeats the classic version of Penofol in everything, but at the same time it is cheaper.

There is also Penofol type C, which means self-adhesive. This insulation has several layers: sewn polyethylene foam, on one side of which aluminum foil is welded, and on the other side, waterproof glue with an anti-adhesive coating is applied. Thanks to the adhesive, the insulation is easily attached to almost any surface, which makes it a great way to insulate the floor in a wooden house.



Gluing joints.

Due to the small thickness and foil, the installation of Penofol is easy and fairly fast. The material is placed on the floor surface with an overlap or end-to-end, and the resulting joints are glued with metallized adhesive tape. When using Penofol, you can forget about the presence of hydro and vapor barrier, since this function is performed by foil.

Use of polystyrene

Expanded polystyrene (polystyrene) is also among the leaders in thermal insulation. Such popularity is due to the huge number of pluses and a minimum of minuses.

Polyfoam has low heat-conducting qualities and is practically vapor-tight, durable and fire-resistant. Styrofoam never molds and does not attract rodents. The cellular structure extends the life of the foam and makes it more effective as a heat-insulating material.

Among the shortcomings of the foam, high moisture absorption can be noted, so attention should be paid to the organization of vapor and waterproofing.

Benefits of using ecowool

Ecowool is a natural insulation, consisting of 80% waste paper and 20% natural additives. It is a mixture of cellulose fibers with boric acid and lignin. Such a composition ensures the environmental friendliness of the material, and therefore safety for the human body.


Ecowool insulation process.

Ecowool is characterized by low thermal conductivity, fire resistance and the fact that if it gets wet, it is worth drying the material, and the thermal insulation properties will be restored. At the same time, ecowool is more expensive than most heaters, but with its use, there will be no repeated question of how to properly insulate a house, including its wooden floor.

New - Isolon

A new type of heat-insulating material was named Izolon. It is made from foamed polyethylene and has a number of advantages over competitors.

Izolon has a small thickness (from 2 to 10 mm.), Which ensures ease of installation, but despite the thickness, 1 mm Izolon corresponds to a brick wall in terms of thermal conductivity, and also looks like from a beautiful photo.

Isolon does not absorb moisture, and also acts as a vapor and water insulator. Isolon is also environmentally friendly, so it can be used in any room, both as a main and auxiliary insulator. Isolon, to all its advantages, also absorbs noise, so it can also act as a sound insulator. There are many materials for thermal insulation available on the market. They vary in cost, installation method, size and properties. before purchasing, it is worth considering all the steps, planning the progress of work, and only then acquiring the material.

But, despite the choice of material, wooden floor insulation is very important and will help keep the house warm, and after reading this material, you should have no questions about how to properly insulate the floor in a wooden house.

Overview of penofol properties

Penofol is a material made from polyethylene by foaming with special reagents. This polyethylene foam is applied to a foil base, to which it reliably sticks. The foil base greatly enhances the thermal insulation properties of the material due to the reflection of thermal waves inside the room.

Therefore, penofol belongs to the class of reflective thermal insulation. This foil insulation has the following performance characteristics:


Advice! There are several product classes: A, B and C. Class A insulation has a foil on one side, and the B series material has two. Class C insulation has a foil base on one side, and an adhesive layer on the other, which makes it easier to install in inconvenient areas.

Application area

Penofol has a versatility of application: it is used for insulation and vapor barrier not only for residential premises, but also for industrial facilities. Here is a far from complete list of where this material is used:

  • Ceiling ceilings.
  • Wall insulation.
  • Waterproofing and floor insulation.
  • Arrangement of warm balconies and loggias.
  • Thermal insulation of air ducts and technical pipelines.
  • Application in the automotive industry for thermal insulation of bodies.

As you can see, the list of applications is quite extensive. We will consider where you can use penofol with your own hands - the home area of ​​\u200b\u200bapplication.

The use of penofol

Even for domestic needs, this versatile material is used quite extensively. Let's consider the main directions.

Most often, penofol insulates the floors in a wooden house. This process is absolutely simple, you can easily do it yourself, just follow this technology:

  1. It is best to remove the old boards and lay several layers of penofol between the lags. In this case, all layers of material must be laid with a foil base inside the room. Then old boards are laid in place or a sheet of plywood is stuffed.
  2. Another way is that the heat insulator is laid on top of wood flooring. One layer of insulation is applied, while the laying is done end-to-end, and the seams must be glued with aluminum tape. Then, sheets of plywood are laid on the laid heat-insulating layer and screwed to wooden base self-tapping screws.

Advice! It is impossible to fix penofol to a wooden base mechanically, for example, with brackets. If there is a need to fix the insulation, it is better to treat it with glue or use an adhesive-based material.

Thermal insulation of concrete floors

As a rule, penofol for warming concrete floors in a house or on a balcony is used in conjunction with other types thermal insulation materials. The technology of work in this case is as follows:


The use of penofol in the underfloor heating system

It is very common to use penofol when arranging a system of underfloor heating, both in a private house and in an apartment or on a balcony. The use of this reflective material increases the heat transfer of the entire system by 15–20%, which, at the current cost of energy carriers, is a significant savings. Penofol is used when installing underfloor heating using this technology:

  • After the main insulation has been laid, foil material is mounted on it.
  • In this case, the general rule is observed: the installation is done end-to-end, the seams are sealed with aluminum tape.
  • For this option, a one-sided option is usually used. If fixation of the reflective layer is necessary, then penofol with an adhesive base can be used.
  • Then an electric cable or a water circuit piping system is mounted on the foil.

Advice! You can cover the heating elements of the underfloor heating system not only with boards or plywood, but also fill it with cement screed. The foil base of penofol is resistant to various aggressive operating conditions.

Having studied the properties and got acquainted in more detail with such material as foil foam, it is easy to agree with the opinion of professionals that this material is an excellent addition to existing insulation technologies. In addition, this insulation can be used as an independent heat insulator.

Penofol classification

Since the production of penofol began, its properties, scope and structure have undergone tremendous changes. Previously, the material looked like a roll of sewn polyethylene foam, one side of which was foiled with aluminum. With the help of this variant of the material, thermal insulation of premises is still performed, since it has high efficiency. In addition to the classic type of penofol, other types of material are produced, which are endowed with a number of useful properties:

  1. With one-sided foiling - type "A". It is used in conjunction with other materials for insulation.
  2. With double-sided foiling - type "B". Offline use is allowed.
  3. Type "C" - one side is covered with special glue and a protective film, and the other side is covered with foil. It is installed by gluing to the surface that requires insulation.
  4. Type "R" and "M" - embossed foam with one foil side.
  5. Type "ALP" - has one-sided foiling up to 14 microns, which is laminated with a polyethylene film.
  6. perforated material. It has a special structure that allows air to pass through.

The type of penofol is selected depending on the type of insulation work, i.e. walls, floor, roof.

Penofol laying technology

Before insulating the floor with insulating material, it is necessary to determine its type and installation technology. It is necessary to lay penofol types "C" and "A" under the finishing floor. The insulation process begins with a concrete screed mixed with expanded clay, or with the placement of foam plastic plates with a thickness of 5 to 10 cm. Then foam foam is spread with an overlap of about 10 cm and all joints are glued with construction tape.

It should be noted that condensation may form on the thermal insulation material, so measures must be taken to prevent this phenomenon. To do this, fill the slats up to 2 cm thick above the foil surface, which will create a ventilated space. If the wooden floor is being insulated, then the role of the rails is played by the logs. It is important to remember that all slats and logs must be impregnated with an antiseptic and drying oil to protect the wood from decay.

If the insulation is carried out using the “warm floor” system, then the penofol is laid with the foil side down on a completely dried screed, and in other cases the material must be placed with the reflective side up. A plastic film is laid over the heat insulator, which will be a vapor barrier. To insulate the floor on the lower floor, located above the basement, type "B" foam should be used.

As a rule, when installing a “warm floor” system, the heating elements must be filled with a screed in order to subsequently obtain a flat surface for laying, for example, a laminate. In such cases, the ALP foam type should be used, since its foil side is laminated with a film, and, as you know, cement is aggressive towards aluminum.

Floor insulation with penofol of this type is performed on top of the primary screed, while the reflective side should be on top. The sheets are laid with a slight bend, about 10 cm, on the walls and they are glued with aluminum tape. Next, heating elements are installed, a reinforcing mesh is laid and the entire floor area is poured with a concrete screed. When the surface is completely dry, it is necessary to trim the free edges of the insulation.

Using penofol for floor insulation is the best solution. With this material, moisture will not penetrate into the room, noise will decrease and it will become much warmer, since the foil surface reflects heat, directing it back into the house.

Of course, it is possible to insulate the floor with penofol in a wooden house, we will discuss this issue in this article.

So how to insulate the floor in a wooden house with penofol?

Penofol is a base made from foamed cellophane, which at the same time performs the function of preserving heat and vapor barrier of the interior. In addition, a foil layer welded on top of the polyethylene recreates thermal self-radiation.

The source does not contain pores - this circumstance means that it does not allow air to pass through itself and gives the insulated system the features of a thermos. it may be needed, when warming baths and saunas, which in the future simply must be and are, a storehouse of warm and damp air, for as long as possible in principle.

penofol

In addition, penofol is spread on concrete or a wooden floor so that it separates the pipes of a water-heated floor from the concrete base on the 1st floor of the building. Let's take a look at how the floors are insulated with penofol in each of these situations.

How penofol is used, and its classification.

A layer of foamed cellophane, in a foam sheet, having air bubbles, due to such oxygen-filled bubbles, in fact, insulation is performed. This same layer should be a layer of 3 up to 10 millimeters.

penofol with foil classification A, C

The foil layer in absolutely all penofol variations is similar, however, it can be welded on one side of the edge, this is the 1st option (classification A), or from 2 edges, option 2 (classification B).

In addition, there is penofol, which has foil on one edge, and on the other, an adhesive layer, this layer is like a self-adhesive tape that can be glued to any non-rough surface (classification C).

In addition, there is penofol with one foil film, which is laminated on top with a layer of cellophane (ALP classification).

Penofol class "A", as a rule, is strengthened to another insulation (polystyrene, styrodur) with support for staples for a stapler or nails. Class "C" is able to stick on them, or directly into the base. Class "B" is used for the purpose of independent fastening.

If you have a wooden floor, and a concrete screed is made on it, how can penofol be laid.

If your floor is cold, it is necessary to first fill in reinforced concrete with expanded clay for about 5 centimeters for insulation, or it can be replaced by a layer of foam plastic with a thickness of 5 cm up to 10 cm thick.

On top of the foam, a layer of foam foam (classification “A” or “C”) is strengthened or glued with a whip on the walls, about ten cm, from each edge. And the joints between the penofol tape are glued with aluminum tape.

Dampness, from which penofol protects the entire constructive system building, having no chance of flowing through it, and will settle on it with small drops of water.

In order to prevent this from happening, it is necessary to organize a space above the foil shell of the penofol for the purpose of air ventilation, with vents and holes through which the atmosphere of warm air from the room is able to freely pass in order to remove this water.

For this fact, slats 1.5-2 cm wide are stuffed onto the penofol from the edge of the foil, forming a space for the purpose of air movement.

The same significance, have every chance to play, wooden logs, if a decision is made to cover the wooden floor. Logs and slats must be thoroughly impregnated with an antiseptic or drying oil.

It is necessary to lay them along the entire length of the floor, retreating from the wall one or two centimeters, with an interval of about thirty-five forty centimeters. The laying horizon of the log is checked by the level, the bending logs must be pressed with split rails, the so-called wedges.

It is placed perpendicularly on the logs, an inch board, and on top of the inch board, a sheet of plywood about 12 millimeters thick (it can be thicker, it depends on your budget).

It is quite possible to use plywood 6-8 millimeters, however, it will need to be laid in at least 2 layers. With a finishing coating, it is possible in this case to choose linoleum or laminate.

How to equip the system (Heated floor).

At the base of the warm floor, penofol is laid with the foil side up (classification “A” or “C”), heating components are placed on it, and between them, depending on the width of the elements, logs are laid, on which the floorboard is directly laid (1st method) .

In the event that a concrete screed is poured on top of the heating components (for example, under a tile), penofol of the ALP classification is required. Since the solution is cement, this will always be a hostile environment for aluminum foil, which is covered with penofol (2nd method).

In order to isolate the floor from any shock resonant rumble, penofol is laid with a twist of ten centimeters on each wall. In a similar way of laying, the concept of "floating floor" is obtained.

In order to guarantee hydro and vapor barrier, all joints of the canvas without exception are glued with a special construction aluminum tape.

Already after laying the heating components, a reinforcing mesh is placed and after that the main pouring of the floor area with a concrete screed is performed. Already after pouring the solution, the sides of the penofol are cut off.

Following this, a sufficiently long period is required for heating the floor and putting it into operation.

Insulation of floors with penofol provides heat, hydro and sound insulation to the coating (reduces impact sound by about twenty decibels) and guarantees uniform heating of the floor plane due to the foil present in the penofol, which effectively reflects heat.

Why is floor insulation worth it?

Warm flooring provides a comfortable stay in the house. From temperature values ​​that are stored in living rooms, to a large extent depends on the health of residents and their well-being.

To minimize heat loss, you need to figure out how to properly install the insulation, which materials have the best characteristics and the longest service life. It is also worth noting that the choice of thermal insulation material is influenced by many factors that cannot be ignored. For example, it is necessary to take into account not only the material from which the building was erected, but also the number of floors, as well as whether the building was built on the ground or a basement (basement) was built under it.

Why do floors need to be insulated?

In a private house from below, the insulation of a wooden floor is carried out in several cases.

If it occurs:

  • the need to get rid of the cold floor of the room, which is located above the basement;
  • the desire to insulate the attic floor;
  • the need for thermal insulation of interfloor ceilings, in this case, not only the rooms are insulated, but additional sound insulation is also achieved.

When to do insulation from below correctly

Above a cold basement, floor insulation is best done from below, while insulation above an attic is recommended to be done from above. This approach is technically competent and allows you to achieve the best results. But when implementing thermal insulation from below, some problems sometimes arise:

  • limited choice of materials;
  • unreliable fixation of the insulation;
  • due to the fact that the installation work is carried out on the ceiling, the masters quickly get tired;
  • the complexity of the implementation of the tasks in a low subfloor.

However, taking care of the insulation from below, you can eliminate the following problems:

  • the appearance of fungus, mold on the surface of a wooden structure;
  • excessive fuel consumption during space heating;
  • violation of the functions of structures due to their decay;
  • lack of conditions for maintaining the optimal regime of temperature and humidity in the premises.

Designing private house, it is necessary to consider thermal insulation measures at this stage. By taking care of the heat in advance, it will be possible to eliminate many problems in the future.

The essence of this technology is the laying of rigid sheets of thermal insulation between the subfloor and the floor covering. Of course, this option is more profitable, but it is only suitable for those regions where the climate is warm and mild.

In a region where winters are quite cold, it is still better to insulate from below. This option of thermal insulation is recommended to choose if there is a minimum space between the ground and the floor level.

If this gap is large enough, the warming procedure will be expensive.

Benefits of bottom floor insulation

In a wooden house, the thermal insulation of the floor should be carried out precisely from below, this option is technically correct. The advantages of this technology are:

  • during the operation of the house, the height of the ceilings in the rooms does not change;
  • the overlap, made of wood, is reliably protected from freezing;
  • there is no need to purchase hard insulation that can withstand the weight of large pieces of furniture and household appliances;
  • the condensate settling line can be shifted outside the wooden structure, so that the building does not rot.

Floor insulation technique

There are two main options for thermal insulation:

  1. Thermal insulation on the joists. Choosing this technology, the insulation in the form of plates has to be laid out in a checkerboard pattern. It also requires ligation of sutures. You should first lay a special film to ensure waterproofing. Fixation of the material can be done both with dowels and with glue. After completing the installation of the plates, the seams are carefully sealed with polyurethane foam, and then the flooring is attached to the logs. If you choose a reliable insulation, such a floor will retain heat.
  2. Insulation ending with a screed. If you are thinking about how to properly insulate the floor in a wooden house, consider the thermal insulation option, which involves creating a concrete screed over the thermal insulation layer. First of all, waterproofing the base is performed. The next step is laying the mesh made of fiberglass. As a result, the structure becomes stronger. Next, a concrete solution is applied over the mesh.

How to choose the right heat insulator

Do not know what is the best way to insulate the floors in a wooden house? Familiarize yourself with the basic requirements for thermal insulation materials, and it will be easier for you to choose the right materials. Due to the presence of certain features in the implementation installation work can only be applied certain types heaters. The list of requirements for them is as follows:

  • high indicators of reliability and efficiency;
  • minimum weight of the material;
  • ease of use;
  • the ability to resist the action of fire to achieve a high level fire safety buildings made of wood;
  • maximum possible density.

Materials for thermal insulation works


The quality of the created thermal insulation layer depends on the technical parameters of the insulation material.

Familiarize yourself with the features of suitable materials for insulation and decide what is the best way to insulate the floor from below in a wooden house in your case, so that it is most profitable and effective.

Now the market represents a wide selection of thermal insulation materials, but it is recommended to choose from the best and most popular options, such as penoplex, mineral wool, penofol, expanded polystyrene.

Mineral wool

Manufacturers of building materials offer several types of mineral wool:

  • slag;
  • stone;
  • glass.

Among the advantages, one can single out a high level of heat and sound insulation, incombustibility, biological stability, resistance to aggressive substances.

  • insufficiently high resistance to mechanical stress, this is due to the strength of the material;
  • low rate of vapor permeability;
  • lack of absolute safety for human health;
  • loss of thermal insulation properties due to the gradual absorption of moisture.

Mineral wool can be purchased in the form of a flexible mat and solid boards.

Basically, buyers prefer Rockwool and Izovol, which are based on mineral wool. The first version of the insulation can withstand loads, does not deform and retains heat well. In a wooden house, floor insulation with Izolon is also more preferable than with mineral wool, since this material has low thermal conductivity, it is non-flammable and more moisture resistant.

Styrofoam

Deciding what is the best way to insulate the floor in the country house from below? Consider another option for insulation - polystyrene foam, which is known to many as polystyrene foam. No wonder it is still popular, because there are many advantages, and the number of minuses is insignificant.

The benefits include:

  • fire resistance;
  • high strength and thermal insulation;
  • the ability to withstand biological effects and the influence of chemical factors;
  • long service life due to structural features.

There are much fewer cons, and they are insignificant, but these disadvantages can be eliminated: the material has low vapor permeability, is subject to the negative effect of moisture and, as it is absorbed, loses its ability to thermal insulation - by providing high-quality vapor and waterproofing.

Penoplex

Floor insulation in a wooden house from below with foam plastic is more effective than thermal insulation made using the two previous versions of heaters. Penoplex is made in the form of plates by foaming extruded polystyrene foam, it is also quite often used for the implementation of thermal insulation measures.

Here are some advantages of insulating a wooden floor with penofol (roll material):

  1. High rates of thermal insulation.
  2. Excellent performance.
  3. Simple installation process.
  4. No need for additional provision of vapor and waterproofing, since for these purposes the insulation contains a layer of foil.

Most often, at the heart of the insulation in rolls there are reflective and translucent materials. During installation, the foam layers are placed with a slight overlap or end-to-end. For reliable fixation in the area of ​​\u200b\u200bthe joints, a metallized adhesive tape is attached.

Instructions for organizing installation work

Do you want to know how to insulate the underground in a wooden house? First of all, check out general rules performing installation work. In this order, any insulation is fixed:

  • creation of a waterproofing layer;
  • the formation of thermal insulation;
  • application of vapor barrier material;
  • attachment structural elements overlaps;
  • laying decorative flooring.

Experts assure that when the layers are formed in this order, the thermal regime will be optimal, and it will be possible to ensure the necessary circulation of moisture in the living rooms.

Thinking through the thermal insulation on the basement floor, it is necessary to prepare beams with a cross section of 50-100 mm. These elements are fixed from below using a layer of insulation, after which the floor is sewn up with boards.

In the presence of hardwood floor on the ground floor, the beams are connected to bars, the cross section of which is 50x50, no more than 50x100. A layer of insulating material is laid between them. After the waterproofing layer, sheathing with boards is made.

Most often, the installation of a heat-insulating layer is carried out along the logs:

  • lay the logs on the finished foundation, keeping certain gaps between the bars - about one 1 m, maximum 1.2 m;
  • fix the sheets of chipboard or plywood with self-tapping screws, as a result you will get the basis for applying a layer of insulation;
  • distribute the insulation material between the lags. Determine the appropriate thickness of the insulation, taking into account its features, but remember that the insulation material should not be thicker than the log;
  • form a waterproofing layer. Experts advise going through this stage to achieve the best possible results. You can skip it, but before you abandon this step, pay attention to the features of the selected material. If a heater is purchased for installation, unable to repel moisture, it is still worth forming a waterproofing layer;
  • install the floor covering. Can apply old version or upgrade the coating with a new material.

When insulating the floor from the basement below and in other parts of the house, follow the indicated sequence of actions.

What tools and materials will be required

Of the tools and materials for laying thermal insulation, the following are required:

  • insulation;
  • building level;
  • screwdriver;
  • construction stapler filled with staples;
  • self-tapping screws;
  • lumber (bars measuring 50x50 mm, boards);
  • reinforced tape;
  • a tool designed to work with wood;
  • materials for vapor and waterproofing (vapor barrier membrane, special film for waterproofing);
  • sheets to create the base of the floor.

Floor waterproofing

Since the air in the basement is not heated, condensation can form on the warm floor.

In cases where moisture is constantly present on the structure, ideal conditions are created for the formation of fungus and mold, and subsequently the process of decay begins. Moreover, it does not matter whether the wood was treated with a special agent before use or not.

Condensate violates the thermal insulation properties of the insulation, gradually penetrating into it, it increases its thermal conductivity. This problem can be prevented by laying a layer of moisture insulation on the cold air inlet side.

vapor barrier

From the residential premises, instead of condensate, warm steam is formed, which also passes through the insulation and, cooling, turns into moisture. The harm to the insulation is that, unlike condensate, water is present not on the surface, but inside the structure. In this option, there is a risk of damage to the heat-insulating material with its subsequent destruction, and the likelihood of rotting of wood elements also increases. It is to prevent evaporation that a layer of vapor barrier is needed.

by the most simple option protection against condensate and steam is a polyethylene film. In some cases, when providing thermal insulation of the basement floor, a waterproofing layer is covered with a moisture-windproof membrane, which not only effectively retains moisture, but also does not allow air to pass through.

Despite the fact that it is possible to increase the level of thermal insulation in the house during its operation in order to reliably insulate the building, it is better to consider this issue at the design stage. If the construction was completed a long time ago, it is possible to insulate the old wooden floor without dismantling, which will not cause much discomfort for residents.

Instructions for the formation of hydro and vapor barrier

Waterproofing


vapor barrier

This task is performed after laying the heat-insulating layer. If mineral wool is used, it is important that there are no gaps in the cells. When laying expanded polystyrene and polystyrene, the stock is not left, the plates are cut exactly to the size of the cells. After completion of installation, to increase the reliability of the insulation, the seams are filled with mounting foam.

Vapor barrier is performed in this way:

  • install the protective membrane over the thermal insulation layer;
  • securely attach the film along the lags and perimeter with staples;
  • attach counter-rails (elements in the form of bars) along the wooden logs, which will become the basis for the flooring;
  • on the surface of the rails, attach sheet material, for example, plywood, apart. As a topcoat, you can use any material according to your own preferences, for example, linoleum, laminated flooring or parquet.

How to insulate a concrete floor in a house

If you are wondering how to insulate the floor in an old wooden house where the floor is made of concrete, check out step by step instructions:

  1. Create a multilayer base that will become a reliable protection for the insulation. In no case do not refuse the waterproofing layer, since the concrete passes moisture well, and gradually it will pass to the layer formed for thermal insulation.
  2. Make a crate consisting of metal or wooden slats. Lay the resulting frame (this step must be completed when implementing classic version floor insulation from below using mineral wool).
  3. Having cut the insulation into strips of the required size, install it into the cells by surprise.
  4. Next, proceed to the organization of work aimed at protecting the heat-insulating layer from evaporation.
  5. over vapor barrier film place a counter batten and plywood or other material of the same type (without the batten, the workflow is faster, but later there are difficulties associated with the installation of the cladding).

Sawdust floor insulation technology

Consider an economical option with sawdust. Work is carried out up to the flooring.

Before performing insulation, treat sawdust with a special antiseptic and dry thoroughly. By this treatment, you can protect the material from mold and rodents.

When the insulation is ready for use, evenly distribute the slaked lime in it with a shovel. To determine the required amount of this material, focus on the amount of sawdust (you will need 1/10 of the insulation taken).

At the next stage, be sure to add gypsum, it will give strength to the heat-insulating material. Keep the ratio 17:2:1 (sawdust: lime: gypsum). After adding water, prepare a moderately steep solution.

Fill the cells gradually, laying the solution in small portions.

Floor insulation with mineral wool

Make sure the boards to be treated are dry. If not, dry them thoroughly first.

Create a waterproofing layer, then lay the mineral wool, after cutting it into pieces the right sizes. Use stainless steel wire and staples as fasteners. Wire can be replaced plastic mesh. The heat-insulating layer will protect against steam with the help of a special membrane.

Floor insulation with penofol

Install the insulation so that its reflective side is directed downward, that is, towards the warm space.

Attach the insulation to the joists, keeping a small gap between it and the rough surface. Secure the material with slats, stuffing them in a perpendicular direction, or construction staples.

Basement floor insulation

If the house provides for the presence of a basement, the process of increasing the thermal insulation properties of the coatings must begin from this particular room, since heat losses are the highest in it.

If you want to learn how to insulate a floor without opening it, consider this procedure:

  • prepare wooden slats of small thickness, securely fasten the vapor barrier film to the ceiling lining with them. Make sure that the overlap is 10 cm;
  • when stuffing wooden blocks, keep gaps between them corresponding to the size of the plates with which it is planned to make insulation;
  • place insulation boards in the cells, securely fasten them with slats or wire mesh;
  • attach boards over the heat-insulating layer.

The process of floor insulation is quite simple and can be done independently. The choice of material remains with the consumer. Consider all the options presented and choose the one that best suits your case.

A cold floor in a wooden house is a common occurrence. It's all the fault of rising from ground cover cold air currents. They penetrate through cracks and make the floor surface temperature uncomfortable. Will help floor insulation in a wooden house from below.

This is what floor insulation looks like during the construction phase

It is necessary to carry out technologically correct work on insulation from below. This provides a number of undeniable advantages:

  • the height of the floor of the room does not change;
  • there is no need to select the stiffness of the insulation, which can withstand the weight of furniture and equipment;
  • there is a decrease in the line of condensate settling outside the structure, which prevents the process of decay of the house.

Placement of insulation - an effective measure of protection from the cold

Getting started, you must select the material and. The determining factor will be design features the buildings, as well as wishes and financial reserves owner. It is important to take into account the key details of the installation and subsequent operation of the wooden structures from which the house itself is made.

Foundation options:

  • foundation on piles;
  • strip foundation;
  • frame type;
  • screw piles.

There are also general specific points that are important to consider:

  1. The use of waterproofing. A crucial step. Prevents swollen boards. It is best to use single-sided fiber.
  1. Double layer method. The best way keeping the heat in the house. To prevent exposure to temperature fluctuations and humidity wooden details buildings are pre-treated by special means protection.
  1. The stability of the heat-insulating material in the vicinity of wood. The selected heat insulator must be inert with respect to the elements of the floor and foundation.

1-lags, 2- cranial bar, 3 - rough floor, 4 - lutrasil (glassine), 5 - shavings (sawdust), 6 - lime mixture, 7 - finishing floor

How to insulate a wooden floor with foam plastic - step by step instructions

Penoplex- last generation material. This is a foamed polymer obtained by extrusion. It has low thermal conductivity due to its strong structure with a large number of cells.

Penoplex is produced in plates, plate thickness two to 10 centimeters. It looks a lot like styrofoam. Does not increase the weight of the structure.

Does not absorb moisture. Expanded polystyrene is not affected by fungi and decay processes.

It should be noted that the thermal conductivity of foam plastic is 25 times lower than the thermal conductivity of expanded clay concrete. This factor significantly increases the insulating characteristics.

The foam density is 22 t/m

Therefore, the material is mechanically strong and does not require a frame to work with it.

If necessary, this heat-insulating material is allowed to be used when installing a "warm floor" (electric and water type). Penoplex is resistant to fire.

The cost of penoplex is slightly higher than the cost of other heaters, but it easily pays off in the cold season.

We will analyze how to act accurately when carrying out work on insulation.

Most convenient way the location of expanded polystyrene foam - alternating with lags, a floor covering is laid on top of them.

Find out how to do it in our dedicated article.

Step 1. We prepare the bases for laying the material.

Lags are installed on finished foundation elements. It is important to observe the distance from the log to the log is 1-1.2 meters. Next, we mount thickened plywood (possibly chipboard sheets), use self-tapping screws.

Preparation for a new floor

Step 2. We lay penoplex.

The insulation has already been laid, it remains to sew up the floor with a finishing board

The height of the insulation layer varies. However, it is worth remembering that it should not be above the laying level of the lag. We must not forget about the layer of waterproofing material. They need to cover the subfloor itself and the logs and directly the insulation layer before laying the flooring. It is also advisable to use wood treatment with solutions of antiseptics and antifungal mixtures.

Step 3. Close up the joints.

We glue the joints of the waterproofing with metallized tape to maintain tightness. Such measures will prevent the absorption of condensate wooden beams, reproduction of mold and fungi.

Step 4. Work with the final floor.

We fix the finishing boards over the waterproofing layer.

How to insulate the floor in a wooden house from below

The choice of insulation for the home can be influenced by the financial resources of the customer or owner, as well as the features of the house (this includes the type of flooring).

In practice, they use well-known heaters:

  • sawdust;
  • foam;
  • expanded clay;
  • ecowool;
  • mineral wool;
  • penofol;
  • penoplex.

Prices for mineral wool

Thermal insulation materials for the floor

1. Mineral wool.

A common heat-retaining medium in use. Flame retardant lightweight material, has good soundproofing properties.

There is slag, stone, glass wool.

Mineral wool in a roll is convenient for work

2. Expanded clay.

Expanded clay - natural material

Expanded clay prices

Expanded clay

It is made from clay or slate. Expanded clay is fired at elevated temperatures.

Table 1. Expanded clay properties.

3. sawdust.

Small wood shavings, wood industry waste.

Fairly cheap, but good insulating effect, able to create sound insulation. They require special treatment to prevent the appearance of rodents and insects in the sawdust. Next, it is mixed with cement and water and applied as a heater. It also makes sense to use clay. This will increase the thermal insulation properties of sawdust.

Sawdust is cheap and practical for do-it-yourself home insulation

When working with sawdust, it is extremely important to carefully lay the material, obtaining a dense and fairly even insulating layer. If the technology is not followed, the effectiveness of thermal insulation is greatly reduced.

4. Styrofoam.

It's styrofoam. Resistant to moisture, fire, chemical factors. Good thermal insulator. Easy to install and keep in good condition for a long time.

Modern foam looks like this

5. Ecowool.

80% cellulose fibers. Waste paper, waste and scrap paper production are used for manufacturing. It also contains sodium tetraborate, which makes it resistant to fire. Boric acid in ecowool provides protection against bacteria and fungi.

Ecowool applied dry

It is advisable to use ecowool for insulation houses from high humidity, as this prevents the appearance of abundant condensate in the walls and other internal environments of the structure.

There are three ways to apply ecowool. This dry, wet and sticky ways.

  • dry application mainly works for country houses;

Cellulose wool is fed using specialized equipment. In the process, dust is created, which is why it is better to use masks, respirators and goggles for the safe installation of insulation.

  • the wet application method is used when there is a need for further wall cladding;

Water is added to the raw material.

The resulting mixture, when solidified, forms a dense mass.

  • adhesive method is used for insulation of reinforced concrete or metal structures.

Insulation of a wooden floor with mineral wool

On the market you can find various modifications of insulation. There is mineral wool in ready-made rolls and slabs.

Capable of absorbing moisture, which means that good vapor barrier is extremely important. In the same time, able to protect the wood of surrounding structures from excessive moisture and decay.

Among required attributes Also gloves, mask and goggles. The fine fibers of the material can cause severe itching, reddening of the skin or irritation of the respiratory tract.

Floor insulation with penofol

Penofol looks like a layer cake. Foamed polyethylene is covered with pure aluminum foil. Sold in large rolls. The penofol sheet has a thickness of three to ten millimeters. It perfectly retains heat, performs high-quality sound insulation, and is safe for the environment at home.

Foil penofol easy-to-work material

The effectiveness of penofol is based on reflection of thermal radiation. This is how heat is retained inside the room. All because of high-quality aluminum foil. Here its properties are close to those of precious metals.

I distinguish penofol with two and with one layer of foil. In addition, there is a self-adhesive penofol.

Penofol is exposed to moisture. However, it is not capable of absorbing moisture by itself.

Penofol does not support combustion

The disadvantages of the material include low rigidity, which can create additional difficulties when working with it.

Fixing penofol may also require additional effort. Punching fasteners cannot be used, because. this will degrade the properties. All that remains is a special glue, which will also have to be purchased.

For work with vertical and inclined surfaces, it is advisable to take self-adhesive penofol.

Now on the market of building materials there are a large number of different insulators in terms of efficiency. One of the modern heat insulators is penofol. This material is great for light thermal insulation throughout the house, it is also possible to insulate the floor with foam.

A special production technology gives this material high thermal insulation properties and other characteristics. An overview of the properties, scope and technology for insulating various surfaces with this material will be discussed in this article.

Overview of penofol properties

Penofol is a material made from polyethylene by foaming with special reagents. This polyethylene foam is applied to a foil base, to which it reliably sticks. The foil base greatly enhances the thermal insulation properties of the material due to the reflection of thermal waves inside the room.

Therefore, penofol belongs to the class of reflective thermal insulation. This foil insulation has the following performance characteristics:

  • Small material thickness. At the same time, penofol has high thermal insulation properties. This allows you to effectively insulate small rooms where a thick layer of thermal insulation is unacceptable.
  • Multifunctionality. This heat-insulating material can be used not only for insulation, it is also recommended to be used as a hydro- or vapor barrier.
  • When used simultaneously with other heaters, penofol enhances their main characteristics.
  • The strength and durability of the material is achieved through the latest production technology. At the same time, the products are environmentally friendly: hazardous substances are not used.
  • Large temperature range of application: penofol does not deform at low temperatures (up to -55 °C) and does not melt at high temperatures (up to +110 °C).
  • Ease of installation and affordable pricing also add to the popularity of this versatile insulation.

Advice! There are several product classes: A, B and C. Class A insulation has a foil on one side, and the B series material has two. Class C insulation has a foil base on one side, and an adhesive layer on the other, which makes it easier to install in inconvenient areas.

Application area

Penofol has a versatility of application: it is used for insulation and vapor barrier not only for residential premises, but also for industrial facilities. Here is a far from complete list of where this material is used:

  • Ceiling ceilings.
  • Wall insulation.
  • Waterproofing and floor insulation.
  • Arrangement of warm balconies and loggias.
  • Thermal insulation of air ducts and technical pipelines.
  • Application in the automotive industry for thermal insulation of bodies.

As you can see, the list of applications is quite extensive. We will consider where you can use penofol with your own hands - the home area of ​​\u200b\u200bapplication.

The use of penofol

Even for domestic needs, this versatile material is used quite extensively. Let's consider the main directions.

Most often, penofol insulates the floors in a wooden house. This process is absolutely simple, you can easily do it yourself, just follow this technology:

  1. It is best to remove the old boards and lay several layers of penofol between the lags. In this case, all layers of material must be laid with a foil base inside the room. Then old boards are laid in place or a sheet of plywood is stuffed.
  2. Another way is that the heat insulator is laid on top of a wooden covering. One layer of insulation is applied, while the laying is done end-to-end, and the seams must be glued with aluminum tape. Then, plywood sheets are laid on the laid heat-insulating layer and screwed to the wooden base with self-tapping screws.

Advice! It is impossible to fix penofol to a wooden base mechanically, for example, with brackets. If there is a need to fix the insulation, it is better to treat it with glue or use an adhesive-based material.

Thermal insulation of concrete floors

As a rule, penofol for warming concrete floors in a house or on a balcony is used in conjunction with other types of heat-insulating materials. The technology of work in this case is as follows:


The use of penofol in the underfloor heating system

It is very common to use penofol when arranging a system of underfloor heating, both in a private house and in an apartment or on a balcony. The use of this reflective material increases the heat transfer of the entire system by 15–20%, which, at the current cost of energy carriers, is a significant savings. Penofol is used when installing underfloor heating using this technology:

  • After the main insulation has been laid, foil material is mounted on it.
  • In this case, the general rule is observed: the installation is done end-to-end, the seams are sealed with aluminum tape.
  • For this option, a one-sided option is usually used. If fixation of the reflective layer is necessary, then penofol with an adhesive base can be used.
  • Then an electric cable or a water circuit piping system is mounted on the foil.

Advice! You can cover the heating elements of the underfloor heating system not only with boards or plywood, but also fill it with cement screed. The foil base of penofol is resistant to various aggressive operating conditions.

Having studied the properties and got acquainted in more detail with such material as foil foam, it is easy to agree with the opinion of professionals that this material is an excellent addition to existing insulation technologies. In addition, this insulation can be used as an independent heat insulator.
