Technical characteristics of the insulation isover. Isover thermal insulation technical data Isover thermal insulation material technical data

Competition in the market for thermal insulation materials is fierce. Manufacturers try to offer new products every year, which are superior to traditional materials in various indicators. Some are trying to modify the old ones, giving them increased technical characteristics.

But among the heaters there are those that remain unchanged in terms of quality, shape, structure and size. This category includes insulation "Isover". These are the products of the Finnish company Saint-Gobain, which has been present on the Russian market for more than 20 years. So our compatriots have long been familiar with this brand and designate it in Russian - isover.

Before us in this article is the topic of the expediency of using this heat insulator. The thing is that isover is a mineral wool made from glass threads, or, more precisely, from fiberglass. Hence the technical characteristics that this insulation has.

Important. Glass production is based on the use of only natural materials, which means that isover is an environmentally friendly material (cotton wool).

Currently, manufacturers have begun to add glass industry waste or recyclables to it. This did not affect the quality, but the cost price decreased significantly. And this is again a big plus.

Specifications

The owner of a large number of advantages, Isover immediately determined its superiority over other types of thermal insulation materials. He did not change the technical characteristics and this won in the rating of modern heaters.

Here are the characteristics:

  • Since it is a heater, the isover is the owner of low thermal conductivity. The indicator is 0.038.
  • High sound protection. We can talk about this material not only isover - a heater, but also sound protection.
  • Made of fiberglass, isover is resistant to bacterial and fungal contamination. It is not eaten by rodents and small insects. So it's great protection.
  • The weak side of the characteristics of thermal insulation material- high moisture permeability. Many porous species suffer from this, including mineral wool.

Advice. Many heaters absorb moisture and do not give it away, while losing their thermal insulation qualities. Isover behaves differently. Made from fiberglass, it dries quickly with rising temperatures or well-functioning ventilation. Therefore, it is laid so that there is a ventilation gap between it and the protective barrier.

  • Low specific gravity (density - 13 kg / m³). It provides simplicity and convenience of application, transportation, loading and unloading. Installation can be done by hand.
  • Ecology has been discussed above.
  • A high degree of stability when exposed to chemically active substances on the insulation, where fuels and lubricants are released.
  • Isover is an elastic material (wool) that can be compressed up to 60% - these are mats and up to 75% - roll type.
  • Service life - 50 years.
  • According to fire safety requirements, isover belongs to the category - non-combustible materials (NG). This is also a big plus.


Insulation is used for thermal insulation of any structure of the house, both indoors and outdoors. For the sake of justice, it should be noted that isover is the owner of not only advantages. He has some shortcomings:

  • It can be used in places where the ambient temperature does not exceed +250 ° C. For housing construction, this is a completely unimportant condition.
  • A tight fit to the insulated structure is obligatory. Under the isover, it is necessary to prepare the surface with maximum evenness, without major flaws.

Dimensional indicators

The manufacturer offers a heater of various forms of release. Here rolls, plates and mats are all designed to increase ease of use. There are single-layer models with a thickness of 5 or 10 cm, there are two-layer models with a thickness of one layer of 5 cm.
Roll insulation has a standard width of 120 cm. The footage of a roll is within 7-14 m. At the same time, the area covered by it varies in the range of 16-20 m².

The lineup

Like any building material, isover insulation is on the market in the form of several types. Each of them is designed for certain building structures:

  • "Sound Protection" intended for finishing partitions, walls.
  • For frame construction, a heater of the model " frame ».
  • "Pro" used for insulation of attics and pitched roofs. This is a high quality heater. Profi is offered on the market in rolls with a thickness of 50, 100 and 150 mm.
  • Classic used in wide application. Floors, logs, attic floors and other complex objects are available for insulation. Although the Classic is a rolled material, it can be used to cover huge areas at a time. Usually two layers of 50 mm are laid in a roll. So it can be safely divided or used as is.
  • Classic Plus . This heat insulator insulates the outer and inner surfaces of the walls. It has high thermal insulation characteristics. An excellent example.

Important. Many models are classified as "interchangeable". That is, one is freely substituted for the other. In this regard, Profi and Classic Plus are universal heaters.

Modern Izover insulation is produced in the base with basalt or glass fibers. The material is obtained by processing quartz sand, mineral rocks of the basalt group and broken glass. The components are mixed, melted at ultra-high temperatures in special furnaces, and then drawn into fibers of different lengths and thicknesses, fastened with a special type of resin.

Isover insulation is produced in two versions: plates and rolls using our own patented technologies in 1981 and 1957.

The main characteristics of the insulation

Thermal insulation materials of the Isover brand from mineral wool inspire confidence and are in stable demand. Moreover, both slabs and rolls are considered to be among the best thermal insulation on the market.

The main characteristics of the heater include:

  1. Thermal conductivity.
  2. Soundproofing.
  3. Flammability.
  4. Vapor permeability.
  5. Long service life.
  6. Environmental friendliness.
  7. Convenient release form.
  8. Light weight.

As a heat insulator, Izover insulation managed to prove itself from the best side precisely due to the thermal conductivity coefficient equal to 0.041 watts per meter per Kelvin. The coefficient does not change during the operation of the insulation throughout the entire period, the fibers do an excellent job of accumulating and retaining air, preventing heat loss.

The material has excellent sound insulation performance. Fiberglass insulation with an air gap absorbs noise, guaranteeing an optimal level of silence, especially if you use specially adapted types of insulation for the sound insulation layer.

Flammability is also important. Thermal insulation materials with technical characteristics indicating a density of up to 30 kilograms per cubic meter are classified as non-combustible. The materials are successfully used in rooms of any type and purpose, without fear of the spread of fire in the event of a fire.

Thermal insulation boards made of mineral wool with special technical characteristics indicating the presence of an additional layer based on aluminum foil or fiberglass are classified as low combustible.

Such materials are used subject to certain restrictions, which in fact are nothing more than a convention. In practice, insulators are appropriate almost everywhere, the main thing is to follow the fire safety requirements for structures prescribed in the SNIp.

An important item from the list of technical characteristics of thermal insulation is vapor permeability. The insulation is able to maintain functionality even after contact with moisture. Unlike many modern analogues for thermal insulation, Izover products based on stone wool simply and effectively cope with the problem of moisture penetration into the thermal insulation layer.

The insulation gives off the absorbed moisture as quickly as it receives, the main thing is to leave a small gap (2-3 cm) between it and the wall to maintain ventilation.

Neglecting this simple rule will lead to a violation of the material's ability to remove moisture, which over time will negatively affect the ability to retain heat. Izover heaters have optimal vapor permeability - from 0.50 to 0.55 mg / mchPa.

Analysis of the technical characteristics of the material implies the mention of such an important parameter as the service life. The material not only does not transmit heat, but is also able to serve properly for several decades. The manufacturer claims a service life for heat-insulating plates and rolls of 50 years with full preservation of functionality.

A feature of the material is the water repellents included in the composition, capable of repelling moisture, preventing the reproduction of insects, fungi and the formation of mold, which in turn ensures safety throughout the entire period of use.

Among the technical characteristics of the insulator, environmental friendliness and complete safety for health play a special role. Izover materials do not pose any risk to life and health, as they are made from natural raw materials.

The light weight of the insulation is not just one of the characteristics, it is a clear and undeniable advantage. If we compare the insulator with analogues, then its weight is an order of magnitude less, which in turn allows us to expand the scope of application by combining the insulation with surfaces made of not the most durable materials.

An excellent bonus from a manufacturer that focuses on improving the technical characteristics of the finished product can be considered the release form. Insulations are available in several versions - rolls, plates, less often - in mats (for example, ISOVER ISOTEC KIM-AL).

The average thickness of a single-layer insulation ranges from 50 to 150 mm. The two-layer insulation has a fixed thickness of 5 cm with standard dimensions of 1 m by 1 m. The roll is produced with an area of ​​​​16 to 20 square meters with a constant width of 1.2 meters and a length ranging from 7 to 14 meters.

The technical characteristics in relation to the combustibility of the heat-insulating material should include the following parameters:

  • combustibility;
  • flammability;
  • smoke generating ability;
  • toxicity.

The combustibility of thermal insulation boards and rolls based on mineral wool varies within 30 kg/m3, if we are talking about a group of non-combustible materials. Semi-rigid and rigid boards coated with film and foil from the group of low combustible are taken out into a separate category.

Varieties and application of insulation

The description of the main technical characteristics of the material confirms the fact that as a heater it is practically out of competition. Plates and rolls are used for internal and external insulation, practicing devices for the thermal insulation layer of rooms and structures of various types and purposes. A heat insulator is presented in a fairly wide range in order to select the most appropriate option.

Thermal insulation for a pitched roof is the most suitable option for insulation:

  • pitched roof from the inside;
  • house insulation for siding;
  • outside pitched roof insulation.

This type of material is characterized by improved moisture resistance, which allows it to be used for insulation of roofs operated in conditions of high humidity.

Another option for stone wool insulation is to improve the quality of sound protection. The material is suitable for insulating partitions, insulating structures for siding, insulating floors along logs and walls inside the house.

Izover for soundproofing has excellent soundproofing properties, indispensable for improving the properties in partitions and other structures.

Another type of stone wool insulation is Izover Classic Plus. The material is suitable for insulation of almost all types of surfaces, has a thermal insulation coefficient of 0.041 W.

It is sold in the form of lightweight plates with a thickness in two versions: 50 mm and 100 mm, in packs of 7 and 14 pieces. Plates Classic are easy to use, suitable for installation in rooms with a limited area. The material does not require the use of special fasteners, it is used to isolate partitions, suspended ceilings and other surfaces. You can buy Izover Classic Plus plates at an affordable price.

Unlike the Classic Izover Sauna slabs, the material is based on fiberglass wool with an additional layer of foil. Products are produced with a thickness of 50 mm and 100 mm, with a width of 1200 mm and a length in two versions - 625 mm and 12500 mm.

From the name it is clear that the insulation is designed primarily for use in saunas, where consistently high temperatures are maintained and additional protection against abundant steam is needed.

The heat-insulating material is safe, durable, sold in packages that are convenient for transportation with a thickness of plates of 50 mm, 100 mm, 150 mm.

Izover Profi also has technical characteristics different from the Classic insulator, which is also produced in the form of rolls and plates. The insulation has a 3D effect, which allows you to insulate surfaces with a snug fit to the base and consoles. In terms of thermal protection, it is the Profi that is considered the most effective and has an indicator of 0.037 W.

The material is available in two thicknesses: Profi boards 50 mm and Izover Profi insulation 100 mm (in rare cases up to 150 mm).

For the insulation of ventilated facades, special heaters are suitable. These are models for warming the outer layer in the case of a two-layer thermal insulation device, guaranteeing minimal heat loss with high thermal protection.

Complete with insulation for the upper layer, Izover VentFacade Bottom is also used for the lower layer, also with excellent thermal performance. The thickness of the plates (50 mm or 100 mm) is determined on the basis of a thermal calculation.

For insulation of single-layer ventilated facades, Izover Facade Mono and VentFacade Optima for low-rise buildings are used.

Another type of plate with a thickness of 50 and 100 mm (in isolated cases 150 mm) is Isover KL34. The materials are tightly mounted on the frame without the use of additional fasteners. The slabs, like the Classic, are suitable for insulating both ventilated facades and multi-layer brickwork, while it will equally effectively insulate horizontal and vertical planes.

Isover KL37 is a heater sold in tightly pressed packs. Just like the previous options, it does not need additional fasteners, it is suitable for installation between floors, roof and wall insulation with maximum adhesion to the surface.

A variation of the previous model - Isover KT37, produced in compressed rolls. Installation of insulation for thermal insulation does not require additional fasteners, the elements fit perfectly to the surface. Used for insulation of roofs, interfloor ceilings, attics and partitions.

Isover KT40 is a two-layer insulation in compressed rolls, suitable for thermal insulation of both vertical and horizontal surfaces.

Isover STYROFOAM 300A - insulation for thermal insulation, the installation of which is complicated by the use of fasteners. Produced in hard rough slabs, excellent adhesion to concrete. The composition includes extruded polystyrene foam, due to which insulated cells are formed that improve moisture resistance. Insulate material both horizontal and vertical surfaces inside and out.

Another variety of ISOVER ISOTEC KIM-AL material in the form of fiberglass thermal insulation mats. The material is developed using a special technology of vertical fiber formation, additionally covered with a layer of aluminum foil to improve vapor barrier and increase service life.

ISOVER ISOTEC KIM-AL mats are used to insulate air ducts of a supply and exhaust ventilation system, process equipment, fittings, flange connections of pipelines, etc.

The main advantages of ISOVER ISOTEC KIM-AL include a special arrangement of fibers, due to which the material during installation retains its original shape unchanged, adhering as closely as possible to the surface. In addition, the insulation increases the level of sound insulation in the room, suitable for thermal insulation of pipes inside buildings.

The advantage of ISOVER ISOTEC KIM-AL is also resistance to chemicals. If we compare KIM-AL with other heaters based on stone wool, then its superiority is obvious - the material is not susceptible to moisture and aggressive environments.

Using material for insulation (it doesn’t matter if Classic is Facade, Pro or soundproofing plates), you need to protect your hands and eyes with gloves and goggles.


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:

  • Classic stove.

  • Skate form.

    Ventfasad.

    Stucco facade.

    floating floor.

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.

Pros and cons of insulation to keep in mind

Like any building 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.

    Fire resistance.

    Long service life - up to 50 years.

    Resistant to temperature extremes.

    Reliable heat and sound insulation.

    Minimum weight.

    No shrinkage.

    Easy installation.

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 - 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.

The ISOVER company (Izover) - in the world market occupies a leading position in the manufacture of insulation for any type of structure.

Izover plates are considered the best heaters in the construction market. Most of the ISOVER insulation production volume takes place abroad, but in Russia the insulation is also produced in the Moscow region, in the city of Yegorievsk. A large plant that produces heat and noise insulation, in addition, the plant is the only one that produces mineral wool based on quartz and basalt.

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). The lower the lambda value, the better the house can be insulated, due to the fact that the thermal conductivity value 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°С. An indicator declared by the manufacturer.

Wet lambdas (installed by the manufacturer at different degrees of humidity):
λA and λB are thermal conductivity coefficients for different operating conditions (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 therefore, 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.
