Availability and excellent thermal performance make profiled timber one of the favorite materials for builders. Many believe that due to thermal insulation, lumber does not need additional insulation. This opinion is often wrong. Below we will understand in which cases thermal insulation is required at home, and how exactly it should be carried out.
Timber insulation is not always required. A warm climate or temporary residence in the house allows the structure to retain heat without additional costs. The fastening system of the profiled timber has no gaps, and this is a plus, since a comfortable temperature for living is maintained inside the building.
This also allows you to save on finishing, since pre-treated lumber does not need additional polishing.
If the construction of the house takes place in a cold climate, or if you plan to stay indoors for a long time, insulation is a must.
Stages of warming a house from profiled timber
All elements of the house need insulation. Therefore, it is worth taking a responsible attitude to each of them. Otherwise, the event will be useless.
Foundation
There are two ways to insulate the foundation:
- internal;
- external.
Internal insulation highly undesirable and recommended only if, for some reason, external insulation is not possible.
External insulation has several advantages:
- materials for it are cheaper than for internal insulation;
- allows you to avoid freezing and, as a result, a sharp temperature drop, which lead to the destruction of the structure;
- allows you to save the internal area of \u200b\u200bthe basement.
The most preferred material for insulation of the foundation is polyurethane foam.
It is more expensive than polystyrene, and has the following advantages:
- its installation does not take much time;
- there are no seams and gaps;
- no cold bridges.
For laying such material, special equipment is used. The thickness of the insulation layer should not be less than 5 centimeters.
A little less often they use a heater - extruded polystyrene foam. It has only a couple of advantages:
- low price;
- absolute immunity to moisture.
Floor
The floor, laid out with boards, will sooner or later be covered with gaps and cracks. And this means that the thermal insulation of the room will drop sharply. To prevent this from happening, they also provide floor insulation. Moreover, it is desirable to do this at the stage of building a house in order to avoid problems with laying boards in the future.
On a note!
thermal insulation floor covering implies not only laying insulation, but also hydro and vapor barrier. What materials will be required is best agreed with a specialist, since the choice depends on many factors, such as the material of the boards, ventilation system in the house and so on.
In order to insulate the floor, logs are installed in the foundation. Then shields are nailed to the timber and a hydro- and vapor barrier, a heater and again both insulations are installed.
This method is not the only one, but is more common in its execution.
Walls
There are only three options for wall insulation:
- external;
- internal;
- interventional.
The last option for those who care about the aesthetics of the room.
As a rule, the following materials are used for thermal insulation of walls:
- natural insulation: linen, sheep's wool, lnovatin and more. Such materials are suitable for interventional styling;
- Styrofoam or any cotton material is ideal for external insulation;
- for the inside - exclusively cotton insulation.
In addition to thermal insulation materials, a vapor barrier will also be required, which will not allow the insulation to absorb moisture.
Warm and cozy house every person's dream. Even wooden house needs insulation, despite the good physical properties of wood. Insulation work can be carried out both inside the house and outside. About how to do it right and choose good materials for insulation, we will talk in this article.
Insulation of a house from profiled timber
Good thermal insulation is not only an indicator of the quality construction of the house, but also a way to reduce heating costs and provide comfort to all residents. Therefore, a house made of profiled timber must be properly insulated. This type of material is most suitable for the construction of private houses. First of all, it is distinguished by a good fastening density, thanks to spike connection. But it doesn't matter if you plan to live in the house all year round it needs to be insulated. Warming should be started even at the construction stage, laying a tape insulation made of jute or flax along the seams. You also need to pay attention to the exterior finish. It will protect the tree from the negative effects of precipitation. To do this, you can choose siding or lining. Under them, you can lay a layer of mineral wool, which will serve as wall insulation. You also need to take care of the internal insulation. The walls must first be laid with foil material, which will reflect heat into the room. Then fix the guides on the walls and fill the distances between them mineral wool, after which everything is sewn up with drywall. Do not use expanded polystyrene, roofing material and similar materials. They have low hygroscopicity and can cause wood decay. In addition, it is necessary to insulate the floor and ceiling. Windows and doors should not have gaps. After completing these simple manipulations, you will get a very warm and comfortable house for year-round living.
How to insulate a house from a bar
Any house can freeze in very coldy. A wooden house built from timber is not immune from this either. In order for the house to always be warm and the walls not damp in winter, the dwelling must be insulated. These works must be approached comprehensively and work must be carried out both outside and inside the premises.
insulation of a house from a bar outside
External insulation has a number of undeniable advantages:
- a significant reduction in heat loss, as a result of a reduction in heating costs;
- additional protection against negative environmental influences;
- updating the appearance of the house;
- there are no losses in the footage of the premises.
It is also necessary to take into account the following nuances:
- use of quality materials;
- observance of laying technology;
- carrying out waterproofing works.
There are three main types of external insulation of buildings:
- hinged ventilated facade;
- installation of insulation under the siding;
- spraying polyurethane foam.
Let's consider each of the methods in more detail.
Ventilated facade allows the walls of the house to breathe. Its installation is not difficult, but requires precision. First of all, on the walls of the house they make a vertical crate of bars, which are fixed with self-tapping screws. Everything must be done smoothly; for this, the crate is checked by a level. After that, mineral wool foxes are laid in the resulting crate, and the material is attached to the walls with special dowels. For ventilation of the facade, a gap of at least 5 cm is required. This can be achieved by attaching bars to the crate. After that, you can sew up the walls with clapboard or siding.
Insulation under siding. This insulation is carried out in the same way as the previous type. The only difference is the absence of a gap between the insulation and the siding. Various materials can be used for insulation:
- mineral or glass wool;
- Styrofoam;
- polyurethane foam.
Polyurethane foam spraying not so long ago appeared on the market for insulation of facades of houses. This process is quite fast and easy to perform. A big advantage is good sound insulation and non-combustibility of the material. The material is environmentally friendly. Also, you do not need additional fasteners. After spraying the material on the walls of the house, it can be sheathed with any finishing material you like.
By choosing one of the presented methods, you will receive high-quality insulation of your home.
home insulation from the inside
Both old and newly built wooden houses need internal wall insulation. The warming process includes several stages:
- wall processing;
- installation of the crate;
- insulation bookmark;
- creation of ventilation;
- interior decoration.
The walls of the house must be treated with antiseptics. This will help prevent the development of fungus and rot in the wood, as well as prevent damage to it by various insects. Even the smallest cracks are processed.
After the surface has dried, it is necessary to seal the cracks. To do this, you need to use jute or linen fiber and a chisel.
After all the cracks are filled, it is necessary to provide a vapor barrier. This will allow the tree not to absorb excess moisture. To do this, a special film must be laid on the walls, ceiling and floor. After that, proceed to the installation of the crate. Beams with a section of 5 * 10 cm are attached to the wall using self-tapping screws. Then we lay the insulating material. Its size should exceed by 1 - 2 cm the distance between the beams of the crate. For reliability, insulation sheets are attached to the wall with special anchors with a large hat. After everything is filled with material, a layer of film can be laid on top. After that, you can start decorating the room. A board or any other material of your choice is laid on the floor. Walls and ceiling can be sewn up with clapboard or drywall. Internal insulation is a fairly simple process. The main thing is to clearly follow all the stages of work.
timber house insulation material
Currently on the market building materials There is a wide range of heaters available. They have different composition and physical properties. Some materials are best suited for outdoor insulation, others are more recommended for internal works. So outside the house from a bar can be insulated:
Styrofoam. This is a fairly popular material for thermal insulation work. It is fixed to the walls of the house with a special glue. Additionally, you can fix the material with special bolts. This material has both positive and negative qualities. The advantages include:
- not susceptible to fungi and mold;
- does not absorb moisture;
- the material is light;
- affordable price (on average, a cubic meter of material costs 1,600 rubles).
The disadvantages include:
- subject to mechanical destruction and needs additional protection;
- airtight;
- must be protected from paints and varnishes that can destroy the foam.
Mineral wool- an excellent material for warming the house. She has excellent physical properties, perfectly passes air, and removes excess moisture. With such a heater, the walls of the house will breathe. Easy to use, easy and quick to install. The cost of packaging the material ranges from 400 to 740 rubles. It all depends on the class of the material.
Styrofoam environmentally friendly material, moreover, it is not subject to combustion at all. With proper installation, insulation from this material will last up to 30 years. On average, the cost of this material is 1300 rubles per package. The number of plates in the package can vary from 5 to 20 pieces.
The choice of material is a personal matter for everyone. You should be guided by financial capabilities and your personal preferences. It is also necessary to take into account the convenience and speed of laying the material.
Proper insulation of a house from a bar
In the insulation of the home, there are also a number of nuances. It is best to start such work after 1 - 2 years from the construction of the house. The beam, like all other materials, shrinks over time. First you need to caulk all the existing gaps with the help of special materials (jute or linen fiber). Both materials are made from natural raw materials and will serve as an excellent heater. It is desirable to insulate the house from the outside and from the inside. Also, do not forget about the floor, ceiling and attic space. After all, a large amount of heat can escape through an uninsulated roof. To insulate walls and floors, you can use different materials which have already been mentioned in the article. The ceiling from the side of the attic can be covered with expanded clay or sawdust, it is quite simple and affordable way insulation, which has been used for a long time. After the main work is completed, pay attention to the windows and the front door, they also need to be insulated. Door insulation can be reduced to two stages:
- box insulation;
- door insulation.
with insulation door frame everything is quite simple now on the market there are various seals. They are made from foam and rubber. Most often they have a self-adhesive backing. Rubber models have proven themselves best. It is enough to glue them to the box from the sides and at the top, this will give a snug fit to the door and, accordingly, eliminate heat loss.
If the front door is thin, then in winter it will freeze through. Insulating it is quite simple, just take:
- foam rubber;
- dermantin;
- decorative carnations.
The door must be removed from the hinges and unscrewed metal elements. It is necessary to put it down so that it is convenient to work. We evenly distribute the foam rubber on the surface, flush with the door. Then we measure a piece of leatherette a few centimeters wider than the door, these are allowances. We begin to nail the material from the sides of the door, for this you can use a construction stapler, after which we fasten the bottom. And lastly, so that the canvas lies evenly, we fasten the top. After that, we upholster the surface of the door with decorative carnations. With their help, you can not only decorate the door with an interesting ornament, but also additionally fix the upholstery. With windows, everything is much easier. Most manufacturers produce compacted and insulated products designed for Russian climatic conditions. Properly insulating a house is not difficult. We must do everything conscientiously and not forget about the little things.
How to insulate walls from the inside
Before insulating the walls inside the dwelling, all the advantages and disadvantages of this method should be noted. The advantages include:
- carrying out work at any time of the year;
- scaffolding is not required.
The disadvantages include:
- reduction in floor space;
- violation of air exchange, as a result of which fungus and mold may appear.
Therefore, the insulation must be selected carefully and it is better to seek the advice of a specialist. When choosing a material, the following factors must be taken into account:
- durability;
- safety for human health;
- fire protection;
- good thermal insulation properties;
- aging resistance and shape retention.
To insulate a house from a bar, it is best to give preference to mineral or basalt wool. This material has a low fire hazard. Service life is 15 years or more. Also, this material has good thermal conductivity and is able to remove excess moisture, which will protect the tree from damage. The main and indisputable advantage is the ease of installation. It is possible to insulate a room with this material without resorting to anyone's help.
This article talks about how to insulate a house from a bar. Attention is paid to both external and internal insulation. It also talks about how to avoid heat loss by insulating doors. Using the tips of the article, you can quickly and effectively insulate your home. Happy warming.

Profiled timber attracts many Russians with its affordability and excellent thermal characteristics. However, most of them mistakenly believe that such a house does not have to be insulated. Of course, I want to preserve the unique wooden flavor of the interior and exterior of the building, but comfortable living is more important. In matters of warming a house from a profiled beam, there are some nuances. We will tell about them today.
When can you not insulate?
In fact, profiled timber does not always need to be insulated. If the house is being built in a region with a warm climate or for temporary (seasonal) residence, then it does not need insulation. The boards fit snugly enough to each other and are able to maintain a comfortable microclimate in the absence of too low temperatures.
Such a cottage is an ideal option for fans of eco-friendly wooden houses. The owners will be able to admire the beauty of the log house both inside and outside in summer. They will also enjoy pleasant coolness in hot weather and warmth in case of an unexpected cold snap.
If the house is built for permanent residence then it needs to be insulated. It is also recommended to make warming in the baths. How to do this depends on the thickness and type of profiled timber.
What is profiled timber?
This material can be very different in cross section. Thanks to this master, it is easy to choose boards for the desired building.
The thinnest profiled beam reaches 95 millimeters in width and 145 millimeters in height.
The rest are significantly larger than 195x145.
You must understand that even the thickest profiled timber is not able to fully protect against the cold in winter. Especially in the far north. The house needs additional insulation.
In any case, it is necessary to carefully select the material. High-quality profiled timber has a high degree of drying (humidity up to 20%). Compliance with the technology in the manufacture of the material prevents shrinkage and deformation of the walls subsequently. For this reason, even when working with the best specialists they need to be controlled when buying timber. You live in the house, and each mistake then repeatedly comes back to haunt you with problems.
The level of thermal insulation to some extent depends on the selected profile. It can also be different:
with one spike;
with two spikes;
with bevelled chamfers;
"comb";
Finnish profile.
Of course, it is easiest to lay the last option, but the “comb” wins in terms of thermal insulation characteristics. If you need to build a house in a region with a harsh climate, choose it.
Stages of home insulation
If you want to minimize heat loss, then you need to thoroughly approach the insulation. It needs a foundation, floor, walls, roof. In each case, it is necessary to take into account the features of the designated elements of the house. Only then will it be possible to make housing truly comfortable.
Foundation
The base of the house is best insulated from the outside. So you save money, protect the foundation from freezing and destruction during sudden temperature changes. In addition, in this case, the basement area will be preserved, which is also important.
Internal insulation is permissible only when external insulation is not possible. The house was originally built without external insulation of the foundation, and this omission must be eliminated.
The main materials for external insulation:
polyurethane foam;
extruded polystyrene foam.
Polyurethane foam has excellent hydro, heat and sound insulation characteristics. It is applied using special equipment. The layer of material must be at least 50 millimeters.
Advantages of polyurethane foam:
work does not take much time;
lack of cold bridges in the foundation;
no gaps or seams.
It takes more time to lay extruded polystyrene foam. However, it costs much less and practically does not absorb moisture, which provides the maximum level of waterproofing.
Insulation must be installed at a freezing depth. This is the most rational use material, means and time.
Installation should be carried out along the walls of the building. This will reduce the depth and degree of freezing.
Even if the floorboards fit snugly together, over time they dry out and gaps form. To avoid removing the coating and carrying out insulation work in the future, it is better to do everything correctly at the initial stage.
Floor insulation involves the use of not only insulation, but also vapor and waterproofing. The choice of materials depends on the type of floor, so before starting work it is better to consult with a specialist.
The most common way to insulate the floor is by joists. To do this, logs are installed in the foundation or log house in a T-shape. From below, shields are nailed to them, on which the necessary materials are installed. First, hydro and vapor barrier, then insulation, and the third layer is hydro and vapor barrier again.
The finished floor is laid after these works.
Can be insulated both outside and inside. There is another option for those who do not want to give up the wooden aesthetics of the beam - interventional insulation.
The choice already depends on your preferences. Do you want to admire the solid wood both in the interior and exterior? Choose interventional insulation. If the only thing that matters to you is appearance at home and is not afraid of reducing the area of \u200b\u200brooms, insulate inside. When only the interior matters, and siding or facing brick seem attractive, external insulation is best suited.
Materials:
for interventional insulation, sheep wool, flax, linen or jute are used, the last option is a novelty on the construction market, which has excellent performance characteristics;
for external insulation, you can take foam or cotton material;
for internal - only cotton wool insulation.
Be sure to install vapor barrier materials to prevent moisture from being absorbed by the insulation. Also take care of the ventilation in the house to ensure a comfortable climate in the house.
The ceiling is insulated in the same way as the floor, and the technology of roof insulation is similar to the thermal insulation of walls. We will not dwell on these points.
For details when carrying out insulation work, it is better to consult a specialist. He will be able to give the best advice in your particular case.
The log house has replaced the traditional log buildings. A special atmosphere of comfort always reigns in it, and the natural wood used provides a favorable microclimate. However, in order for the house to become truly comfortable and warm, it is important to take care of the insulation. Thermal insulation material in such buildings fills the intervention space.
Types of building material
The beam has several varieties.
- The most accessible regular or whole(unprofiled). It is a log sawn from all sides, due to which it has a square section measuring 150-220 mm. Such material is more prone to shrinkage, adverse effects of the environment than others. Over time, it cracks, due to discrepancies in the geometry and dimensions of individual products, gaps form in the structure. It is better to use such a beam if further sheathing is planned from the inside and outside.
- Profiled the beam has a more precise geometry, it is equipped with spikes and grooves. Due to this, the appearance of cracks during the installation process is minimized. Outwardly, it is more attractive - there are no knots, blackouts, cracks on the surface. Since profiled timber, like regular timber, is cut from a single log, it also shrinks. However, it is less prone to deformation than the non-profiled counterpart.
- The least shrinkage gives the house glued timber. These are boards of cedar, pine or larch fixed together, which are thoroughly dried beforehand. It is drying that ensures the absence of warpage. Such material does not need additional processing, it has a convenient fastening system, and is distinguished by precise geometry. Compared to analogues, it has the highest cost, but cannot be considered completely environmentally friendly due to the presence of glue in the composition.
Features of the procedure
The use of interventional insulation allows you to solve the following tasks:
- preservation and improvement of the thermal insulation qualities of the massif;
- increase the life of the building;
- preventing the ingress of moisture from the outside, the appearance of mold and fungus;
- ensuring vapor permeability.
Proper insulation log house will significantly increase its thermal efficiency, eliminate cold bridges that invariably arise between the elements of the timber.
The walls will become windproof even for a squally wind. Internal insulation will maintain an optimal balance of temperature and humidity. Sensitive to changes in these indicators, wood will not be deformed due to a significant temperature difference between inside and outside the room.
What is the best way to insulate?
In ancient times for warming log house used waste from household fabrics. They were of plant origin, and therefore differed in safety and vapor permeability. This contributed to maintaining the optimum temperature and natural humidity in the house. Today criteria quality material are low coefficient of thermal conductivity, vapor permeability and environmental friendliness.
We must not forget that wood annually undergoes fluctuations in the linear size of the timber (a newly built house shrinks). Therefore, it is necessary to choose an elastic, elastic material that will be able to contract and expand without losing its technical properties. Traditional interventional heaters are flax (the rough parts of the plant that remain after the preparation of raw materials for linen fabric), jute, tow and felt (made from sheep's wool). Let's take a closer look at their modern modifications.
Lnovatin
Flax fiber (linen felt) is a non-woven material based on flax, obtained by pressing. The release form is strips 8.5-200 mm wide and 5-7 mm thick, rolled into a roll. Standard roll length is 2000 mm. The advantage of using flax fiber for timber is its environmental friendliness. It does not cause allergies, it is made from purified flax (not from industrial waste).
Linen felt has good adhesion and provides uniform insulation of the entire surface of the interventional gap. In addition, it has soundproofing abilities.
The use of flax fiber allows you to maintain an optimal microclimate in the room. The material takes away excess moisture, with an excessive decrease in air humidity, it gives it away.
It is worth noting the ease of installation of flax fiber.
To give the building an attractive finished appearance allows a jute cord fixed over the insulation. However, if the material is fixed under drywall, the use of a cord can be abandoned. Like any material, linen felt has disadvantages: insects can settle in the thickness of flax fiber, mice take it apart.
Jute
This material is a modern interventional insulation, the basis of which is a recycled annual tropical plant lime families. Its unique resins are a powerful antiseptic. They protect not only the insulation itself from decay, but also wooden surfaces walls. In addition, the presence of resins makes the material unattractive to rodents.
Jute for timber can be purchased in the form of rolls or ropes. The first varieties have a thickness of 15 mm, their width varies between 100-200 mm, the length is 2000 mm. Ropes are often used as a decorative element, since jute has an attractive golden hue that blends harmoniously with natural wood. The high content of resins has a downside.
The material quickly sticks together and dries. This leads to a decrease in its volume and the appearance of cracks in the wall. This can be avoided by mixing jute with flax fiber. The result is linen jute (the percentage of flax and jute is 50 x 50%) and jute felt (the ratio of flax and jute is 10 x 90%).
Tow
Felt
The basis of the material is natural sheep wool, which provides high sound and heat insulation characteristics of the material. To ensure the biostability of raw materials, they are treated with special impregnations. The advantages of the material are its elasticity and elasticity. Thanks to this, it fills the entire space without leaving cold bridges.
When a house shrinks or wood expands, under the influence of high humidity, the felt expands or contracts. This ensures the invariability of its thermal insulation qualities. It does not absorb moisture, does not shrink during operation, is a vapor-permeable material. The only drawback is the high cost. It is produced in rolls, the thickness of which is 12-18 mm, and the width varies from 90 to 200 mm.
artificial
In addition to traditional heaters today, you can find on sale artificial materials. For example, these include heat-insulating material produced in the form of tapes based on polyester fibers. It has a low coefficient of thermal conductivity, vapor permeability, repels moisture. All this ensures the biostability of the product, its ability to maintain a pleasant indoor climate.
Demanded heat-insulating insulation is PSUL(pre-compressed sealing tape) based on polyurethane foam impregnated with acrylic. A feature of the product is the ability to expand after installation, filling the entire interventional space. The durability of PSUL is another advantage. Its service life reaches 20 years.
Widely used latex, silicone, acrylic sealants, with which you can eliminate interventional gaps and get rid of cracks in the wood that occur when the material dries. Sealants fill cracks and free spaces, which prevents the formation of cold bridges. They do not absorb moisture, but at the same time they are vapor permeable. Due to the elasticity of the sealant, it can be used even in newly built houses.
It is easy to use the sealant due to the convenient release form (tubes). Due to the variety of shades, it does not need decoration. The material has good adhesion to wood and other materials. This makes it possible to use it in houses that have wood concrete, foam blocks or other building blocks as a foundation.
Important point– sealants are not suitable as the only insulation with primary caulking. They should be combined with elastic synthetic insulation, and also used to eliminate cracks in the beam itself after shrinkage.
Manufacturers Overview
Polyester-based artificial insulation has become widespread. The Finnish company Politerm is considered the leading manufacturer of such materials. This product should be trusted only because wooden construction is widespread in Finland, and harsh winters are in many ways similar to Russian ones. The material is safe for humans. Even after years of use, it does not decompose and does not emit toxins.
Despite the artificial origin, the material is characterized by vapor permeability, fire resistance and chemical inertness.
It has a low thermal conductivity and is characterized by its ability to expand and contract. This prevents the formation of gaps as a result of shrinkage of the house. The kit includes special curly elements designed to connect the nodes of the log house.
The most adapted to the operating conditions in the Russian climate are products from the domestic manufacturer Avaterm. It has the same advantages as the Finnish counterpart. The service life of this insulation is up to 200 years. Products designed with technical features houses from different type timber (glued, profiled).
When drilling, material particles are not wound around the drill. It easily passes through the insulation, leaving smooth edges at the perforation site.
Among the reputable manufacturers of sealants for interventional insulation are the products of Сonseal, Neomid Warm Seam, Weatherall and Wepost Wood. These materials are characterized by high performance characteristics.
How to do the work yourself?
Immediately after construction, the interventional spaces are insulated from the inside, that is, they carry out the primary caulking. To do this, the rolled insulation is twisted and the space between the logs is filled with a chisel. Those who make repairs with their own hands should know that they first caulk the lower link around the entire perimeter. Only after that you can rise higher, working around the entire perimeter. If you first completely caulk one wall, and then the second, this can lead to warping of the house.
First of all, the interventional space should be cleaned of dust and litter. Next, the heat-insulating material is twisted, applied to the gap and hammered into it with blows of a chisel, mallet. Excess material is cut off.
When using synthetic insulation, it is recommended to apply a layer of sealant over them.
A year later, the biggest shrinkage of the house will occur, after which you can start warming. Before insulating the walls, you need to check the condition of the wood and interventional material. When cracks and cold bridges appear, it is necessary to re-caulk. After that, antiseptic solutions and antipyrines are applied to the walls. In rooms with high humidity air, it is recommended to treat the timber with water-repellent compounds (for example, drying oil).
Further internal insulation involves fastening around the entire perimeter of the vapor barrier material. It is fastened with overlaps of 10 cm and fixed with a stapler. It is necessary to protect the house with a vapor barrier layer so that it breathes, and the wood and insulation are not saturated with moisture vapor.
If you plan to use penofol (insulation based on foamed polyethylene with a foil layer) or mineral wool, a vapor barrier layer is not needed.
Designing a house from beams in without fail provides insulation from the outside or from the inside. The microclimate of the building depends on this, the level of humidity, which is vital for human well-being.
Compared with houses made of stone, silicate blocks, bricks, the insulation of a log house from the inside has its own specific features.
Preliminary work
To carry out the work you will need:
- special tool;
- vapor barrier film;
- thermal insulation materials;
- work instructions;
- preliminary preparation.
It is necessary to eliminate:
- cracks;
- gaps;
- chipped.
It is strongly recommended to pay special attention to the condition of the walls, to evaluate the quality of the insulation work already carried out, if any. The choice of material and further actions depend on the quality of the processing of joints, joints of bars, corners.
The most common defects:
- lack of insulating material;
- thinning of the caulking layer.
Attention! All work on wall insulation will be nullified in the absence of foundation insulation, which is desirable to be done at the stage of excavation. If the foundation is not insulated, it will need to be excavated and insulated.
Features of the preparatory work
The most common materials used to correct chips, cracks and other defects are:
- tow linen or jute fiber;
- polymer compositions;
- assembly foam.
Do not neglect this stage, relying on the properties of the advanced finishing materials and the quality of the beams. Compliance with construction technology is the basis for a successful result.
The most common mistake that accompanies the insulation of the walls of a log house from the inside is an attempt to speed up the process. Even the most expensive material is not able to keep the heat in the room, if all sorts of defects that have arisen during the shrinkage process are not repaired.
To eliminate gaps, you need to carry out the following work:
- thicken;
- caulk.
One of the most popular and affordable materials used for sealing gaps is jute fiber. If you do the work with your own hands, you will need a special chisel, with its help fill the recesses without hindrance.
For large gaps ideal option tape tow is considered, which must be twisted into a roller.
Wood processing
Insulation of a timber house inside provides for compliance with mandatory sanitary and hygienic requirements that prevent the spread of fungi and mold. There are more than enough antiseptics of various prices on sale, which are recommended to be purchased in accordance with the specific features of the climate.
Stages of insulation
Material selection
Requirements for materials used for insulation:
- ease of use;
- environmental friendliness;
- safety for humans and the environment;
- fire safety;
- durability.
To carry out work, it is necessary to purchase exclusively safe materials that prevent negative effects on humans. To this end, you should carefully study the factory instructions, which contain comprehensive information, including regarding installation.
There are special heat-insulating materials covered with a film during the production process, their price differs accordingly, however, the advantage is obvious: a reduction in the duration of the installation work and no costs for vapor barrier.
Attention! Insulation of a bath from a bar from the inside is carried out according to the same rules as the insulation of a house. Only materials need to be selected such that the state of which is not affected by high temperature.
Wall vapor barrier
If thermal insulation without a film is used, after carrying out preparatory work you can safely proceed to the vapor barrier. The main purpose of this stage is to prevent moisture condensation on the surface of the walls due to sudden temperature changes.
The traditional method of vapor barrier, which provides the desired effect and has a low price, is a vapor barrier film.
High-quality vapor barrier eliminates the settling of excess moisture. The spread of fungus and mold is excluded. Carrying out this type of work will ensure a long service life of the structure, a normal microclimate in the room.
Floor insulation
In addition to the walls, the insulation of a house made of timber 150x150 from the inside provides for appropriate work with the floor. This type of work has been considered mandatory since the appearance of the first timber houses. The insulated floor reduces the overall heat loss by 20%, which is a very high figure in construction.
The most simple and affordable option floor insulation with mineral wool is considered, if for some reason the floor is already covered, do not hesitate to dismantle it, otherwise it will be very problematic to keep warm. First of all, they line the subfloor, lay on it waterproofing film, heater. Expanded polystyrene is popular.
This requires prior preparation:
- it is necessary to fall asleep and level the gravel cushion, by about 40 cm;
- the layer is carefully compacted;
- sand is poured on top - 10 cm;
- poured reinforced concrete, for complete drying of which it takes about two weeks;
- a plastic film is laid on the finished base and only after that - polystyrene.
Ceiling insulation
Ensuring the thermal insulation of the ceiling is no less significant stage, especially in areas with northern climatic conditions.
The most common materials that do not require special training are:
- polyplex or foam;
- polyethylene foam;
- mineral wool;
- expanded clay.
In addition to special modern materials many people prefer classic version- sawdust.
The advantages of this material are obvious:
- availability;
- environmental friendliness;
- ease of use.
To ensure a long service life of sawdust, it is imperative to use a special antifungal agent, it is also useful to use a fire retardant to increase fire resistance.
Conclusion
