Bulk weight of isover. Technical characteristics of insulation isover

Thermal insulation is an invariable component of any construction. Currently, materials from this category are presented on the market with a very diverse assortment, so it can be difficult for the buyer to make the right choice.

Among the variety presented, ISOVER brand insulation enjoys stable popularity. This is a trademark of the world-famous Saint-Gobain concern, which supplies its products to the domestic market. over 20 years. During this time, a certain opinion has already formed about the Izover insulation. Therefore, we suggest that you familiarize yourself with the features and characteristics of this material.

Manufacturing technology "Izover"

What is ISOVER? This is a mineral wool-based insulation, which is available in rolls, slabs and soft mats. However, regardless of the form, the products are manufactured using the same technology. The process looks like this:

The raw material used is a mixture of quartz sand, limestone, soda ash, microscopic glass particles.

The components are mixed and heated to a temperature 1300 degrees. As a result of thermal action, the solid components are melted, turning into a viscous homogeneous mass.

The resulting composition is loaded into a special installation (centrifuge), the bowl of which rotates at great speed. The walls of the working container have holes through which the molten substance is squeezed out, forming thin threads.

Then the resulting glass fiber is mixed with an adhesive based on polymeric materials.

The mixture is repeatedly subjected to heat treatment, simultaneously leveling the layers with steel shafts.

At the final stage of production, the insulation is cut into strips, following the specified dimensions.

Varieties of thermal insulation

The line of insulation ISOVER has several items. Each of the varieties of produced material has its own characteristics, which determines the scope of application. In particular, the following categories of insulation can be found on the market:

Basic characteristics can be found in the markings on the packaging. It looks like this:

OL-E. The only material in the series that is used for outdoor work. The material has high density and non-porous structure.

KL. Soft boards designed for insulation of internal partitions and ventilated facades.

AL. Insulation with this marking has a layer of aluminum foil on the surface, which acts as a vapor barrier.

KT. This is a roll insulation used to insulate large areas.

Knowing these features, you can easily choose a heater to solve specific construction problems.

Scope of fiberglass products

"Isover" is considered a universal insulation, therefore it is suitable for performing such work:

Heat and sound insulation of external wall structures.

Arrangement of ventilated facades.

Sound insulation of internal wall partitions.

Industrial ventilation systems, pipelines.

Pros and cons of insulation to keep in mind

Like any construction material, ISOVER has its advantages and disadvantages. By the way, the advantages of insulation are much greater, which largely determines its steadily growing popularity.

TO strengths relate:

Wide range of products.

Ease of storage and transportation.

Long service life - up to 50 years.

Resistant to temperature extremes.

Reliable heat and sound insulation.

Obvious shortcomings are considered:

Lack of environmental safety.

Dependence on external factors: perfectly absorbs moisture.

Some builders attribute the soft structure of the insulation to the disadvantages, which somewhat limits its scope.

Material Specifications

With an optimal price / quality ratio, thermal insulation has the following technical characteristics:

High thermal conductivity: 0.033-0.037 W/mK.

Flammability class NG: does not ignite and does not support combustion.

Wide operating temperature range: without deformation withstands heating up to 6000 degrees.

Density: order 15 kg/m2.

Moisture absorption: 0.08 kg/m per day.

It needs to be clarified that these are averages. The insulation is produced in a wide range, so the density and thermal conductivity may vary.

Which is better, Izover or Rockwool?

These brands of insulation are direct competitors in the construction market, so consumers are interested in which material to prefer. It should be immediately clarified that both heaters have similar characteristics, however, they are produced using different technologies.

ISOVER - mineral wool, made on the basis of fiberglass, is produced by a French company. ROCKWOOL is basalt wool produced in Poland. Considering that the second insulation is made on the basis of basalt rocks, the production technology completely excludes the presence of glass. Therefore, Polish products are considered more environmentally friendly.

If we talk about which insulation is better, then there is no clear answer: it all depends on the application. In particular, Izover is better suited for warming the floors of the first floors, non-residential roofs, balconies and loggias.

This is due to the fact that non-compliance with the installation technology can lead to the fact that microscopic particles of glass will float in the air of residential premises, which can adversely affect health. "Rockwool" does not suffer from such a "disease", therefore it is optimally suited for interfloor and internal wall partitions.

Do not forget that ISOVER is much cheaper, which for many is a decisive factor when choosing a heater.

Subtleties of working with ISOVER insulation

When working with the material, personal protective equipment should not be neglected. Gloves and a respirator are a must during installation.

Directly laying the insulation is not difficult. The wall is cleaned of dirt, covered with a waterproofing film. Then a crate of wooden bars or an aluminum profile is installed. The insulation fills the space between the bars, there is a layer of vapor barrier and finishing on top.

Briefly about the manufacturer

As mentioned above, ISOVER is a trademark of the Saint-Gobain industrial group. The company has 350 years of history headquartered in Paris. The company has representative offices in 67 countries of the world. In addition to ISOVER, Saint-Gobain produces ISOROC and ISITEC brand insulation.

On the territory of Russia, the enterprises are located in Yegorievsk and Chelyabinsk near Moscow. The products are manufactured according to the original technology, are subject to mandatory international certification, and comply with GOST standards. It should be noted that since 2013, enterprises launched a production line for the production of basalt wool under the brand of the same name.

Izover insulation: specifications, photo, price

You can easily get lost in the trade names of building materials, especially when you deal with them from time to time. In addition, all the names are very often similar. This also applies to Isover insulation, which was originally produced and developed in France, and came to us about 25 years ago. It was first used in the mid 1930s light hand Saint Gobain. As before, this is a material based on fiberglass and mineral fibers, but thanks to localized production, the price of the material has ceased to be European with a fairly good quality.

What is Izover

Izover insulation, the technical characteristics of the photo, the price of which will be shown below, can be supplied in a wide variety of shapes and formats. It depends on where it is used. Only one thing remains unchanged - it is an insulating material based on mineral fibers and fiberglass. The first quality of any insulation should be the minimum coefficient of thermal conductivity. The tables show the characteristics of several types of material and the maximum thermal conductivity of the universal Isover. It is about 0.036 W / m³ and may fluctuate depending on the density of the material.

The material itself is a fiber structure. The length of the fibers can be from 120 microns, and the thickness is not more than 4 microns. It is these indicators that guarantee the material high strength with minimal thermal conductivity and a sufficient amount of air held inside the material. The production technology is patented and not a single material can simply physically have the characteristics that Izover of any type declares.

Characteristics of Izover

Minimal heat loss guaranteed simple property air placed in the closed space between the fibers of the material, this is what makes the material so warm. In addition, Izover can also be used as a sound insulator and the company declares it as absolutely safe for health. It can be used not only for external insulation of facades, but also for internal insulation of rooms in a residential building, including children's rooms.

The vapor permeability of the material is also of great importance, since the accumulation of moisture in the structure of the material leads to a loss of thermal properties. However, when Izover insulates foundations, plinths and facades, experts recommend leaving at least 2 cm for sufficient ventilation. For water repellency, the material is impregnated with water repellents, which guarantee the absence of not only moisture, but also biological threats. Therefore, the manufacturer can guarantee a 50-year service life of the material.

Safety, weight and price

According to GOST, Izover is considered non-combustible when used in the form of clean slabs, mats and rolls. In combination with aluminum foil or film, it can be considered low-flammable, but this is enough from a safety point of view to calmly insulate with material internal walls residential buildings, not to mention facades. Izover in this sense has no restrictions on the use.

One of the distinguishing qualities of the material is its very light weight. This is important if you take into account the cost of equipping the battens, fastening materials and additional elements that are used during installation. Also, the low weight of the insulating structure reduces the load on floors, walls or roofs. The price of the material is also quite worthy. With a high level of localization of production, it was possible to achieve the price level of domestic materials, and this is about 130-180 rubles per square meter insulation. Packing an insulator can cost from a thousand to 1,500 rubles, depending on the brand.

Dimensions, density and types of insulation

The density of a material can play a decisive role when it is used in certain conditions. For example, the densest insulation has a density of 120 to 160 kg / m³ and is used for roofing, and the least dense with an indicator of 28-38 kg / m³ can be used for both walls and facades. Izover for the floor has a density of 150-165 kg / m³.

The size of the material and the form of release can be very different, depending on the scope of application. For example, for a foil moisture-resistant Izover for wet rooms, it can be produced in rolls with a thickness of 50 to 100 mm, and the length of the unfolded roll will be within 1.25 m. different sizes, while the material is perfectly cut and processed, and the size of the plate is selected based on the size and surface area, so as not to allow a large amount of waste.

Areas of application for insulation

Given the universal properties, low price and various forms of release, the use of the material can be very versatile. For example, the main areas of use of Izover are:

For baths and saunas, a foil isover is used.
Ceilings, interfloor ceilings are insulated with a less dense material.
Izover of increased density is used for floors and roofs.
It is used when installing plastic windows.
For insulation of balconies.
For insulation of basements and basements.
Interior partitions are insulated, taking into account the fact that the material has good sound insulation.
For facade insulation.

Reliable and durable material (the manufacturer declares 50 years of warranty operation) can be an excellent insulation not only for a private house, but also for an apartment, as well as for non-residential buildings. Good luck to everyone and warm homes!

What you need to know about Izover insulation. Characteristics

Known in the world since 1937, the Isover or Isover brand has been selling its products in Russia and the CIS for several decades. Thermal insulation Izover is mats, slabs and rolls of stone wool and glass wool. Today we will understand their features.

Let's briefly dive into the history and facts

The Isover brand is owned by the French company Saint-Gobain, headquartered in Paris. The company was founded back in 1665 by order of the French king Louis XIV. By the way, it is noteworthy that at that time the company was engaged in the manufacture of mirrors and glass. And in the name of the brand "Isover" two words "insulation" and "glass" are used. Today in Russia, the brand has two factories that produce heaters. One makes materials from stone fiber, the other from fiberglass. Isover thermal insulation in Russia used to be sold under the name Uteplyaev.

Purpose

In its line, the manufacturer has several dozen items of materials designed for insulation and sound insulation:

· And other objects.

The fields of application of these materials are shown schematically below.

General characteristics of thermal insulation "Isover"

Perhaps, within the framework of one article, it is difficult to pay attention to each direction in the line, so we will reduce approximate General characteristics these materials.

The main characteristics of Izover insulation:

Thermal conductivity: 0.031-0.041 W/m2*K,
Combustibility: from G1 (slightly combustible) to NG (non-flammable),
Vapor permeability: 0.50 - 0.55 mg / mchPa,
Service life: up to 50 years,
The air permeability is 120*10-6m3/m×s×Pa,
Thickness: from 50 millimeters.

These are only average indicators, it is always worth going to the official website of the manufacturer for the most accurate indicators. Below in the table we give, for example, more accurate characteristics of lightweight insulation.

Also, for information, we provide a table of characteristics of Izover mats Classic

stone wool

Minvata Izover (basalt wool) is produced at a plant in Chelyabinsk, and is produced only in the form of a plate with different indicators rigidity.

Isover mineral wool is the following products of the line:

A little later we will describe the features of each representative of this line. By itself, Izover mineral wool is more expensive than fiberglass materials.

The size of the plate, as always, is the same 1200 by 600 mm. The thickness varies and is shown in the size chart below.

glass wool

The cheaper and more commonly used Izover glass wool is represented in the product line:

Izover Classic (classic Izover),

Quiet and warm roof,

· Uteplyaev (Universal, only for Siberia).

Let's focus on three popular types of materials:

Description of materials. Both of the first materials are soft fiberglass roll mats. However, the numbers in the index refer Isover KT 37 to the corresponding class 37 of thermal insulation, and Isover KT 40 provides a twin insulation - two mats are stacked on top of each other. The total thickness is 50 and 75 mm.

The thermal conductivity of Izover KT 37 and 40 is corresponding - 0.037 and 0.040 0.040 W / m K. The width of the rolls in both cases is the same 1220 mm. For both, it is necessary to build a crate and materials are used for internal wall insulation and other internal work. Density about 15 kg per cubic meter. Sometimes you can also find the marking Isover KT Special (KT Special) - this is a heater in rolls of the same series. The details are given below.

Insulation Izover 37 and 40 specifications and dimensions:

Isover KL 37 material in the form of mats (Isover soft plates have a density of 16 kg / m3). This series is intended for isolation:

In those places where there will be no load on the insulation (that is, in the frame and along the logs).

Below in the table you can see the characteristics of Isover kl 37

Model KL 34 has a lower thermal conductivity than the 37th.

For the sauna there are certain types foil material. One side of the mat is covered with foil, which prevents it from getting wet.

The density and dimensions of Izover correspond to GOSTs. The declared parameters of Izover insulation and technical characteristics correspond to the market as a whole.

The cost of insulation, especially during a crisis - especially important topic. In this article, we will not be able to give prices for all options, but nevertheless we will show the main ones.

For example, the Sauna model in a roll 6250 long, 1200 wide and 100 mm thick will cost about 1400 rubles.

Isover KL 37, 10 plates in a package, with a plate thickness of 100 mm, will also cost about 1400 rubles.

A pitched roof, 20 slabs, each 100 mm thick, will cost 1000 rubles.

Here is a screenshot of the cost from a popular online store.

What do those who have already used Isover insulation say? Let's read their opinions:

They insulated the walls of the house with Rockwool stone wool and worked without glasses and gloves. It remains to insulate one wall and there were not enough plates a little. We decided to save money, the price for 8 plates of 50 mm thick is 350 rubles. Savings when buying Isover 20 rubles on each plate. While my husband was at work, I undertook to lay the insulation myself. I didn’t wear any protective equipment, as before, it was tin. I cough, I sneeze, I scratch. I covered it with foil and screwed the drywall. Even after two days, the insulation stinks. I also covered everything from above with expensive photo wallpapers ... it's a pity to shoot. But, there was no choice left when you sleep, the feeling that you breathe dust. The little child did not sleep for three nights. Pulled this heater and ordered a new one. It’s a pity, of course, money, I was once again convinced that it’s better to be more expensive, but once. Hope it helps someone. Wall insulation with Izover inside - it seems to me not an option at all.

It is worth remembering that Izover highlights harmful substances- phenol (stinks). The higher

room temperature, the stronger the odor and the more substances released. It is recommended to cover the cotton wool with a film from above and below. As my repair experience has shown, under the cotton wool, from the side of the ceiling, it is necessary to put it. It is advisable to secure it well with a stapler. Do not forget to glue the joints - so the smell in the room will be much less. (Even if you don’t feel it yourself, the evaporation is still there).

I work as an engineer and I have to select materials that will be both inexpensive and effective. I decided to use Izover for the pipeline.

For as long as I can remember, pipes have always been insulated with green wool. It is very prickly and has almost no effect - people's pipes are still cold. We decided to do something about it. Has found Isover - has attracted the low price. They wrapped the pipe, plastered it on the grid and left it for the winter to check. The pipes lie on the surface, so it should just be visible how the insulation works.

So, snow fell, +115 inside the pipe, if there was also a plus on the plaster, a snow crust would form, but no, everything is fine, the pipe is cold on top.

I calculated the costs and it turned out that, taking into account all the rules, the price would be 2 times lower compared to other materials.

After that, the entire enterprise switched to Izover thermal insulation, and now we have insulated not only pipes, but also walls, roofs, and facades, especially ventilated ones.

The material performed well and did not deteriorate over time. A vapor barrier is required when installing on facades and roofs. It cuts just fine with a regular knife.

In this article, the characteristics of Izover were given. We also cited reviews from real consumers for an objective assessment. When carrying out thermal insulation work, for example, wall insulation, you will have something to take into account in relation to this brand of thermal insulation.

Izover insulation and its technical characteristics
Izover insulation: specifications. Isover insulation dimensions. Popular brands of insulation and the cost of it.

Isover insulation was originally developed and produced in France, and came to us about 25 years ago. It was first used in the mid-30s of the last century with the light hand of Saint Gobain. It is a material based on fiberglass and mineral fibers. Thanks to localized production, its price has ceased to be European with a fairly good quality.

What is Izover

Izover insulation can be supplied in a wide variety of shapes and formats. It depends on where it is used. Only one thing remains unchanged - it is an insulating material based on mineral fibers and fiberglass. The first quality of any insulation should be the minimum coefficient of thermal conductivity. The tables show the characteristics of several types of material and the maximum thermal conductivity of the universal Isover. It is about 0.036 W / m³ and may fluctuate depending on the density of the material.

Characteristics of Izover

Minimal heat loss is provided by the simple property of air placed in the closed space between the fibers of the material, which is what makes the material so warm. In addition, Izover can also be used as a sound insulator and the company declares it as absolutely safe for health. It can be used not only for external insulation of facades, but also for internal insulation of rooms in a residential building, including children's rooms.

Safety, weight and price

According to GOST, Izover is considered non-combustible when used in the form of clean slabs, mats and rolls. In combination with aluminum foil or film, it can be considered low-flammable, but this is enough from a safety point of view to calmly insulate the internal walls of residential buildings with the material, not to mention the facades. Izover in this sense has no restrictions on the use.

One of the distinguishing qualities of the material is its very light weight. This is important if you take into account the cost of equipping the battens, fastening materials and additional elements that are used during installation. Also, the low weight of the insulating structure reduces the load on floors, walls or roofs. The price of the material is also quite worthy. With a high level of localization of production, it was possible to achieve the price level of domestic materials, and this is about 130-180 rubles per square meter of insulation. Packing an insulator can cost from a thousand to 1,500 rubles, depending on the brand.

Dimensions, density and types of insulation

The size of the material and the form of release can be very different, depending on the scope of application. For example, for a foil moisture-resistant Izover for wet rooms, it can be produced in rolls with a thickness of 50 to 100 mm, and the length of the unfolded roll will be within 1.25 m. Universal insulation can be up to 100 mm thick and produced in the form of plates of various sizes, at the same time, the material is perfectly cut and processed, and the size of the plate is selected based on the size and surface area, so as not to allow a large amount of waste.

Areas of application for insulation

Given the universal properties, low price and various forms of release, the use of the material can be very versatile. For example, the main areas of use of Izover are:

For baths and saunas, a foil isover is used.
Ceilings, interfloor ceilings are insulated with a less dense material.
Izover of increased density is used for floors and roofs.
It is used when installing plastic windows.
For insulation of balconies.
For insulation of basements and basements.
Interior partitions are insulated, taking into account the fact that the material has good sound insulation.
For facade insulation.

The building materials market constantly offers new types of products for home insulation. One of the brands that can satisfy the needs for any kind of thermal insulation is Izover. The characteristics allow the wide use of plates or mats of this brand throughout our country. The company's products are widely used in the private sector, in industry and in the laying of communications.

In order to get a high-quality result when using such a material, before buying, you need to understand the technical characteristics of the Izover insulation. This is a fiberglass-based mineral wool made using TEL technology.

Is the density of thermal insulation materials important:

Main indicators:

The thermal conductivity is 0.041 W×m−1×K−1, which makes it possible to retain air without changing its properties in various climatic zones.
Maximum sound protection is achieved due to the porous structure of the material.
Average density - 13 kg/m³. Depending on the type of insulation, it may vary slightly in one direction or another.
Fire safety is explained by the low previous indicator, which guarantees the absolute incombustibility of the product. Therefore, the use of Izover is allowed in commercial and residential premises, cottages and high-rise apartments. Foil boards are non-combustible. The main condition will be full compliance with fire safety standards when laying the material and operating the structure.

The main indicators of Izover mineral wool:

problem modern heaters is the formation of condensation inside the layers. Fiberglass solutions have special water-repellent components. They contribute to the removal of moisture and increase vapor permeability. In Isover, it is 0.5-0.55 mg / mPa. When installing, it is recommended to leave a two-centimeter gap from the wall.
Depending on the type and conditions of use, mineral wool from Saint-Gobain can last from 50 to 100 years.
The absence of harmful emissions during operation guarantees the environmental friendliness of the insulation.
The low weight, the lowest in its segment, allows the use of this building material even in weak load-bearing structures.
The dimensions of the plates and rolls allow the use of insulation with maximum rationality.

Advantages and disadvantages

If we take into account all the properties of Izover thermal protection, we can derive several positive qualities when using it:

Excellent thermal insulation.

Tolerance to extreme temperatures.
Fire safety.
Immune to warp.
Ease of peeling.
Breaking strength.
Waterproof.
High level of noise absorption.

Isover insulation pros and cons:

When working with Isover products, the following precautions must be observed:

Restrict access to the construction site during work.
As a fence, use a film, plywood or GVL.
Use personal protective equipment: overalls, goggles, respirators.

Preparation method

In order to achieve the required qualities, it is necessary to observe all the required technological norms and processes during production. Izover is made in this way:

A mixture of quartz sand, soda ash, limestone, glass waste and other minerals is prepared.
This composition melts at a temperature of about 1300 degrees. The result is a homogeneous plastic mass.
Further, it is fed into a bowl rotating at high speed with small holes in the walls. Through them, it is squeezed out by long thin threads under the action of centrifugal force.
Mixed with polymeric yellow glue, a sticky substance is obtained, which enters the oven for rolling and drying.
The seized layers are cut into the desired formats with a circular saw.

Production of insulation Izover:

Types of thermal insulation

All materials produced under the Isover brand differ from each other in terms of functional purpose and physical properties. Industrial and domestic categories of insulation are supplied separately. There are some of the most sought after varieties of products from Saint-Gobain.

Types of thermal insulation Izover:

Minvata Izover KL 34

This is a mineral plate 5 or 10 centimeters thick. It is used when frame construction and does not require additional fastening with dowels. This product is characterized by high elasticity, which maximizes the scope of application.

The insulation is packed in a bag. After opening, it instantly takes original view and ready to install. Another advantage of this modification is low shrinkage. Among the technical characteristics it should be noted:

Thermal conductivity - 0.034 W / mk.
Vapor permeability - 0.53 mg / mchPa.
Nominal compression at 2 thousand Pa - 60%.
Return to normal - 98%.

Thermal insulation of walls and floors:

This material is completely non-combustible with an operating temperature of -70 to +250 degrees. If it is completely immersed in water, then it will absorb moisture no more than 5% of its mass, and when wetted - no more than 1%.

pitched roof

This modification is intended for use as a roof insulation. It is produced in the form of mats with a size of 117 × 61 centimeters and a thickness of 5-10 cm. It has almost one hundred percent hydrophobicity. This is its main advantage over competitors - the ability to use in conditions high humidity without loss of properties.

The following indicators are typical for this variety of Izover products:

Thermal conductivity - 0.035 W / mK.
Steam conductivity - 0.55 mg / mchPa.
Absorption at partial immersion - 0.08 kg/m² for 25 hours.

What you need to know when choosing a heater

Thermal conductivity coefficient (λ)

When choosing thermal insulation products, firstly, it is necessary to pay special attention to such an indicator as the coefficient of thermal conductivity - λ (lambda). How less value lambda, the better the house can be insulated, due to the fact that the value of thermal conductivity reflects: how much heat passes through the insulation per unit time.

Thermal conductivity coefficient is measured as W/(m*K). (watt per meter per kelvin)

Types of thermal conductivity (λ)

Dry lambdas (installed by the manufacturer at the factory):
λ10 - coefficient of thermal conductivity, fixed at 10°C. An indicator declared by the manufacturer.

Wet lambdas (installed by the manufacturer at different degrees of humidity):
λA and λB - thermal conductivity coefficients for different conditions operation (according to SP 50.13330.2012). Measurements are carried out by licensed laboratories at material moisture content of 2% and 5%. The coefficient is used in heat engineering calculations in construction.

Choose a heater according to the value of thermal conductivity, because the lower the coefficient, the more efficiently the house will be insulated. For example, if the thermal conductivity value is 0.036, this will be enough for 50 mm of thermal protection to replace 95 cm of brick

Which insulation to choose: in slabs or rolls?

All ISOVER products have high elasticity, which means that the material is firmly and stably held without the use of additional fasteners. Both rolls and plates are used in different designs. The form is determined depending on the room.

Convenience when insulating large surface areas, ease of installation due to the fact that one roll can insulate a large area of the house.
When used, fewer joints appear, and consequently, the permeability of air flows decreases.
Small consumption of material.
Suitable for non-standard rafter pitch, easy to cut to the required width.

Recommended for warming small rooms.
Suitable when working for one person.
Fixed by surprise without the use of additional fasteners.
