What you need to know when choosing insulation

Thermal conductivity coefficient (λ)

When choosing thermal insulation products, firstly, you need to pay special attention to such an indicator as the thermal conductivity coefficient - 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 of time.

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

Types of thermal conductivity coefficient (λ)

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

Wet lambdas (set 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 humidity of 2% and 5%. The coefficient is used for thermal calculations in construction.

Choose insulation based on its thermal conductivity value, because the lower the coefficient, the more effectively 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 holds tightly and stably without the use of additional fasteners. Both rolls and slabs are used in different designs. The shape is determined depending on the room.

Convenience when insulating large surface areas, ease of installation due to the fact that one roll can be insulated large area Houses.
When used, fewer joints appear, and therefore, air flow throughput decreases.
Low material consumption.
Suitable for non-standard rafter spacing, easy to cut to the required width.

Recommended for insulating small rooms.
Suitable for one person use.
They are fixed by surprise without the use of additional fasteners.

Do-it-yourself installation of Izover mineral wool

For thermal insulation various designs The manufacturer has a wide range of products. Thermal insulation material should be selected based on its characteristics (mainly density) and the manufacturer’s recommendations. Mats with a low density are better suited for horizontal surfaces; for thermal insulation of walls it is better to buy slabs with a higher density.

Izover 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 light hand Saint Gobain company. This is a material based on glass fiber and mineral fibers. Thanks to localized production, its price is no longer European, but the quality is quite good.

What is Izover

Izover insulation can be supplied in a wide variety of forms and formats. It depends on where it is used. Only one thing remains unchanged - this insulation material based on mineral fibers and fiberglass. The first quality of any insulation should be a minimum thermal conductivity coefficient. The tables indicate the characteristics of several types of material and the maximum thermal conductivity coefficient of the universal Isover. It is about 0.036 W/m³ and can vary 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 no more than 4 microns. It is these indicators that guarantee the material high strength with minimal thermal conductivity and a sufficient volume of air retained inside the material. The production technology is patented and no other material simply physically can have the characteristics that Izover of any type declares.

Characteristics of Izover

Minimal heat loss is ensured simple property air placed in a closed space between the fibers of the material is what makes the material so warm. In addition, Izover can also be used as a sound insulator and the company declares it to be 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 also has great importance, since the accumulation of moisture in the structure of the material leads to a loss of thermal properties. However, when insulating foundations, plinths and facades with Izover, experts recommend leaving at least 2 cm for sufficient ventilation. To make it water-repellent, the material is impregnated with water-repellent agents, 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-flammable 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 safely insulate with the material interior walls residential buildings, not to mention the facades. Isover in this sense has no restrictions on its use.

One of the distinctive qualities of the material is its very light weight. This is important if you take into account the costs of lathing equipment, fastening materials and additional elements that are used during installation. Also, the low weight of the insulating structure reduces the load on the floors, walls or roof. The price of the material is also quite reasonable. With a high level of localization of production, it was possible to achieve the price level of domestic materials, which is about 130-180 rubles per square meter insulation. Packaging 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. Isover for flooring has a density of 150-165 kg/m³.

The dimensions of the material and the form of release can be very different, depending on the scope of application. For example, foil moisture-resistant Izover for wet rooms can be produced in rolls with a thickness of 50 to 100 mm, and the length of the unraveled roll will be within 1.25 m. Universal insulation can have a thickness of up to 100 mm and are produced in the form of slabs different sizes, while the material is perfectly cut and processed, and the size of the slab is selected based on the size and surface area in order to avoid a large amount of waste.

Areas of application of insulation

Considering 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:

Foil-coated isover is used for baths and saunas.
Ceilings, interfloor ceilings insulated with less dense material.
High-density Izover 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 insulating facades.

Reliable and durable material (the manufacturer declares a 50-year warranty) can be an excellent insulation not only for a private home, but also for an apartment, as well as for non-residential buildings. Good luck with your choice and warm homes!

Isover mineral wool is one of the leading manufacturers of mineral wool fiberglass thermal insulation materials in the world. These insulation materials have proven themselves as quality products, with an optimal ratio of price and performance characteristics.

Rolled mineral wool Izover

From this article you will learn what types of Izover thermal insulation exist, their characteristics, and how they differ from each other. We will also study reviews and find out why these mineral wool insulation materials are better than similar products on the market.

1 Scope of application of Izover thermal insulation

Thermal insulation materials from the French company Izover, in addition to excellent insulating abilities, also have good noise-reducing properties, which significantly expands the scope of their application.

Stitched mats made of Izover mineral wool are widely used both in industrial construction, for insulation of interfloor ceilings, and free space hollow inside brick walls, and in household thermal insulation of residential premises. According to reviews, Izover insulation products perform much better in practice than products from the main competing manufacturers - Ursa and Rockwool.

Using Izover mineral wool insulation, you can thermally insulate any surface. The company produces materials for internal and external thermal insulation of walls, insulation attic floors, ceilings of pitched and straight roofs.

An important advantage of Izover thermal insulation is such characteristics as flexibility, resistance to deformation, and tensile strength, which allows it to be installed on structures complex shape, such as pipes, industrial equipment, elements of production lines, etc.

As already mentioned, Izover mineral wool from the French company “San-Gobain” has both stone thermal insulation Isobox has soundproofing properties. It is often used for insulation production premises And apartment buildings. Mineral wool qualitatively protects the room from any impact and airborne noise.

2 Types and technical characteristics of Izover insulation

Under the Izover brand, very a large number of different mineral wool insulation materials with different functional purposes. The company divides its products into two categories - for industrial and for domestic use.

Let's consider the most popular types of thermal insulation materials Izover.

3 Isover KL 34

Slab insulation, the thickness of which can be 5 or 10 centimeters. This material is intended for frame installation and does not require mandatory fastening with dowels. Model KL34, as evidenced by reviews, is characterized by high elasticity, which makes it possible to install it on any surface.

KL34 slabs are supplied in double-pressed packaging, after opening which the material immediately returns to its original shape. The thermal conductivity of Izover KL34 is 0.034 W/mk, vapor permeability is 0.53 mg/mhPa.

Among the advantages of this model, it is worth highlighting recovery after any deformation and resistance to shrinkage. The nominal compressibility of KL34 under a specific load of 2000 Pa is 60% like Ecover insulation, and the return after compressive loads is 98%.

KL34 corresponds to the flammability class NG - completely non-flammable material, and can be used in temperature range from – 70 to +250 degrees. Moisture absorption KL34 at full immersion in water for 72 hours is 5% of total mass slabs, with partial immersion for 24 hours - 1%.

Line of insulation Izover K (l - slab, t - roll)

4 "Pitched Roof"

Material intended for insulation inner surface roofs of the house. The release form is slabs 5 or 10 centimeters thick, 117 cm long, and 61 cm wide.

The advantages of Pitched Roof wool include its high hydrophobicity - the material practically does not absorb moisture even when completely immersed in water for a long time, which makes it possible to effectively use it in difficult wet conditions, in which other insulation materials would lose their thermal insulation abilities.

Technical characteristics of Izover “Pitched Roof” are as follows:

thermal conductivity coefficient - 0.035 W/mK, similar to Izba insulation;
vapor conductivity coefficient – 0.55 mg/mchPa;
Moisture absorption during partial immersion in 25 hours – 0.08 kg/m².

The density of this material is 15 kg/m3, it shows good return deformation properties. In terms of flammability, “Pitched Roof” belongs to the class of non-combustible materials NG, which makes it possible to use it for thermal insulation of industrial premises.

The area of the slabs in one package of such insulation is 14.27 m², the weight of the package itself is 10.8 kg.

5 Isover KT37

Izover KT37 is a rolled thermal insulation material for insulating the internal parts of buildings made of concrete, brick, wood and aerated concrete. Consumer reviews indicate that it is perfect for insulating the inside of walls, attic or interfloor ceilings and joists.

KT37 belongs to the category of soft thermal insulation; the material has a density of 15 kg/m3, which does not allow the use of this material on surfaces experiencing severe mechanical loads.

Compared to the original volume of the roll, the packaged KT37 is compressed almost 2 times, which greatly simplifies its transportation; the volume of one package is 0.16 cubic meters, after opening - 0.71 cubic meters.

The thermal conductivity of Izover KT37, as well as the Rockwool Wired Mat 80 slab, is comparable to other insulation products from this company; it is 37 W/mk, which makes even single-layer insulation with this mineral wool quite effective.

The thickness of a KT37 roll can be 50 or 100 mm, length - 630 cm, width - 60 cm. The roll form of the insulation makes it possible to cover large surfaces much faster than can be done with slab material. In terms of flammability, the product is classified according to the European standard A1, which corresponds to our NG class (non-combustible material).

6 Isover KT40

Isover KT40 is a two-layer heat-insulating material, produced in roll form, intended for wall insulation frame houses, installation in the middle of false walls and thermal insulation of free space inside hollow brick walls.

Double-layer Izover KT40

The thickness of the KT40 roll is 100 mm, and, thanks to the two-layer design, the product can be divided into two rolls of 50 mm each. The overall characteristics of KT40 are as follows: roll length – 700 cm, width – 61 cm, the area of one package of insulation is 17.08 m².

By thermal insulation properties KT40 is somewhat inferior to the rest of the company’s products; its thermal conductivity coefficient is 0.04 W/μ. The material has high vapor permeability (about 0.5 Mg/mPa), which makes it the best option for insulation of walls of wooden and frame houses.

According to flammability standards GOST 30225 KT40 belongs to the class of non-combustible materials NG. This mineral wool is not intended for thermal insulation of surfaces subject to difficult wet conditions.

The moisture absorption of the material during partial immersion is about 15% of the total mass, as a result of which when installing KT40 it is better to install an additional waterproofing layer.

7 Isover “Venti”

Ecowool Izover Venti is a slab mineral wool insulation designed for thermal insulation of ventilated facades. Venti's technical characteristics are quite serious, especially in terms of strength - an order of magnitude better than that of ordinary mineral wool.

9 Product reviews

Finally, a few reviews from those who are familiar with the material first-hand.

I am a foreman in a team that performs insulation of low-rise buildings. Previously we used Rockwool mineral wool, but we have been using Izover for a year now. I can say that it is better than Rockwool in all respects. We hear only positive feedback from clients. In general, I recommend it.

Victor, 35 years old, Rostov:

I recently insulated the façade of a house with Izover. I spent a long time choosing between it and Rockwool mineral wool, eventually deciding that Rockwool was not worth the money they were asking for it, and settled on Izover. I didn't regret it.

I did all the work myself, I can say that it is quite easy to work with slab insulation. I believe that in this price category there is no better insulation than Izover.

Technical characteristics of Izover insulation

Technical characteristics of Izover - description of the material, list of variations. Advantages of using Izover thermal insulation.

Isover insulation - types and characteristics

Modern insulation Izover is produced with a base of 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 over high temperatures in special ovens, after which they are drawn into fibers of different lengths and thicknesses, fastening special kind resin

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

Main characteristics of insulation

Isover brand thermal insulation materials made from mineral wool inspire confidence and are in stable demand. Moreover, both slabs and rolls are rightfully considered one of the best thermal insulation on the market.

The main characteristics of insulation include:

Thermal conductivity.
Soundproofing.
Flammability.
Vapor permeability.
Long service life.
Environmental friendliness.
Convenient release form.
Light weight.

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

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

The flammability index also matters. Thermal insulation materials with technical characteristics indicating a density of up to 30 kilograms per cubic meter are classified as non-flammable. The materials are successfully used in premises 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 slightly flammable.

Such materials are used subject to certain restrictions, which in fact are nothing more than a convention. In practice, insulators are suitable almost everywhere, the main thing is to follow the instructions fire safety structures prescribed in 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 analogs for thermal insulation, Izover products based on stone wool simply and effectively cope with the problem of moisture penetration inside the thermal insulation layer.

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

Neglecting it simple rule will lead to disruption of the material’s ability to remove moisture, which over time will negatively affect the ability to retain heat. Izover insulation materials have optimal vapor permeability values - from 0.50 to 0.55 mg/mchPa.

Analysis of the technical characteristics of the material implies mention of such important parameter, as the service life. The material not only does not allow heat to pass through, but is also able to serve properly for several decades. The manufacturer declares the service life for thermal insulation boards and rolls for 50 years with full preservation of functionality.

A special feature of the material is the water repellents included in the composition, which can repel moisture, preventing the proliferation of insects, fungi and mold formation, 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 lighter 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, its weight is an order of magnitude less, which in turn allows you to expand the scope of application by combining the insulation with surfaces made from less durable materials.

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

The average thickness of single-layer insulation ranges from 50 to 150 mm. The two-layer insulation has a fixed thickness of 5 cm with standard sizes 1 m by 1 m. The roll is produced in 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 regarding the flammability of thermal insulation material include the following parameters:

The flammability 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 slabs coated with film and foil from the group of slightly flammable materials are placed in a separate category.

Types and application of insulation

The description of the main technical characteristics of the material confirms the fact that as an insulation material it is practically unrivaled. Plates and rolls are used for internal and external insulation, practicing the installation of a thermal insulation layer of rooms and structures different types and appointments. The heat insulator is presented in a fairly wide range in order to select the option that best meets the requirements.

Thermal insulation for pitched roofs is the most suitable option for insulation:

pitched roof from the inside;
insulation of the house under siding;
insulating the pitched roof from the outside.

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

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

Isover for sound insulation has excellent soundproofing properties, indispensable for improving properties in partitions and other structures.

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

Sold in the form of lightweight slabs with two thicknesses: 50 mm and 100 mm, in packs of 7 and 14 pieces. Classic slabs are easy to use and suitable for installation in rooms with limited space. The material does not require the use of special fasteners; it is used to insulate partitions, suspended ceilings and other surfaces. You can buy Izover Classic Plus slabs at an affordable price.

Unlike Classic Izover Sauna slabs, it is a material based on fiberglass wool with an additional layer of foil. The products are produced in thicknesses of 50 mm and 100 mm, with a width of 1200 mm and lengths 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 stable high temperatures are maintained and additional protection against excessive steam release is required.

The thermal insulation material is safe, durable, sold in packages convenient for transportation with slab thicknesses of 50 mm, 100 mm, 150 mm.

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

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

Special insulation materials are suitable for insulating ventilated facades. These are models for insulating the outer layer in the case of two-layer thermal insulation, guaranteeing minimal heat loss with high thermal protection performance.

Complete with insulation for the top layer, Izover VentFacade Bottom is also used for the bottom layer, also with excellent thermal performance. The thickness of the slabs (50 mm or 100 mm) is determined based on thermal engineering calculations.

To insulate single-layer ventilated facades, Izover Facade Mono and VentFasad Optima for low-rise buildings are used.

Another type of slabs with a thickness of 50 and 100 mm (in some cases 150 mm) is Isover KL34. The materials are tightly mounted on the frame without the use of additional fasteners. The slabs, just like Classic, are suitable for insulation of both ventilated facades and multilayer brickwork, and it will be equally effective to insulate horizontal and vertical planes.

Isover KL37 is an insulation material sold in tightly compressed packages. Just like the previous options, it does not require additional fasteners and is suitable for installation between floors, insulation of roofs and walls with maximum adherence to the surface.

A variation of the previous model is Isover KT37, produced in compressed rolls. Installation of insulation for thermal insulation does not require additional fasteners; the elements adhere 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 is a thermal insulation material, the installation of which is complicated by the use of fasteners. It is produced in hard, rough slabs and adheres well to concrete. The composition includes extruded polystyrene foam, due to which insulated cells are formed that improve moisture resistance. Both horizontal and vertical surfaces inside and outside are insulated with the material.

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

ISOVER ISOTEC KIM-AL mats are used for insulation of supply and exhaust air ducts ventilation system, technological equipment, fittings, pipeline flange connections, etc.

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

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

When using insulation material (it doesn’t matter whether it’s Classic Facade, Pro or soundproofing slabs), you need to protect your hands and eyes with gloves and goggles.

Characteristics and types of Izover insulation

Main characteristics of Izover thermal insulation. Its varieties, areas of application. Advantages and disadvantages of the Isover material.

In trade names building materials You can easily get lost, especially when dealing with them from time to time. In addition, all the names are very often similar.

Dimensions, density and types of insulation

The dimensions of the material and the form of release can be very different, depending on the scope of application. For example, for foiled 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 loose roll will be within 1.25 m. Universal insulation can have a thickness of up to 100 mm and is available in the form of slabs of various sizes, at the same time, the material is perfectly cut and processed, and the size of the slab is selected based on the size and surface area in order to avoid a large amount of waste.

Areas of application of insulation

Considering 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:

Foil-coated isover is used for baths and saunas.
Ceilings and floors are insulated with less dense material.
High-density Izover 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 insulating facades.

This also applies to Izover insulation, which was originally produced and developed in France, and came to us about 25 years ago. It was first started

Izover insulation: technical characteristics, disadvantages and advantages

The most popular roll and tile insulation is isover. It bears the name of a company that has patented the production of a material from sand, limestone and soda, which is also capable of retaining heat. Thanks to these properties, ISOVER provides high thermal insulation as well as sound insulation. It can be used for insulation, both indoors and outdoors.

Technical characteristics of ISOVER insulation

Glass fibers are the basis of ISOVER. The length of one of a thousand fibers reaches 150 microns with a thickness of 5 microns. These parameters make the material very elastic and durable.

ISOVER can be used at any stage of building construction. Manufacturers promise the highest level of thermal protection.

ISOVER technical characteristics are as follows:

Low thermal conductivity coefficient. It provides a high degree of thermal protection
Excellent sound reduction properties. Provides the ability to significantly reduce noise levels
Highly environmentally friendly material. Can be used to insulate any room
Durability. This material can last at least 5 decades
Non-flammability. It really doesn’t burn, but at high temperatures it can melt
Light weight. Thanks to this indicator, isover can even be used for insulation of stacked structures

The density of the airtight ISOVER is 13 kg/m3. During installation, it is possible (due to the softness of the material) to reduce the tightness of the seal to the wall.

Types of ISOVER insulation

The manufacturer does not produce universal material. Considering the high technology of the production process, Isover can be manufactured for:

Light thermal insulation. TEL technology is used in production. Slabs and mats are produced. Can be used as wall insulation wooden house or brick, for insulating roofs, should not be used for insulating foundations and floors
General building insulation. There are also several varieties:

Soft fiberglass slabs for frame structures,

Roll mats are used without fastening elements,

Mats, one side of which has a foil base,

Medium hardness slabs

Special products. It's about about ISOVER for pitched roofs. This material has high hydrophobic characteristics, it does not burn and has high level vapor permeability

The ISOVER markings for civil engineering are as follows:

KL – slabs
KT – mats
OL-E – special hardness mats
The numbers indicate the thermal conductivity class

Application of ISOVER

The scope of ISOVER is very diverse. It can be used for insulation

roofs, attic spaces, building facades, interiors, suspended ceilings, floors, plinths and foundations.

ISOVER KT40 is recommended for use when insulating ceilings and floors. This is a material consisting of two layers that can be easily separated. Installation of horizontal surfaces does not require additional fastening
ISOVER STYROFOAM 300A is a tile material that requires mandatory fastening when installed on vertical surfaces. Can also be used successfully on horizontal surfaces
ISOVER KL 34, ISOVER KL 37 – slabs that are sold in compressed rolls. The material is used as insulation for walls inside the apartment, for insulation internal partitions, for thermal insulation of ceilings, attics

When using ISOVER indoors, a vapor barrier will be required.

How to insulate walls and floors with Izover?

You need to work with this material in the same way as with any other insulation. The main thing to know is that high-quality insulation is a multi-layer cake. And then it will be positive result, when the order of composing the layers of this pie is observed.

Wall insulation

In order to mount Izover on the wall, it is necessary to make a lath. These can be wooden planks or metal. Then you will need to attach drywall to them.

The technique for performing the work may be as follows:

The walls need to be primed
Attach the heat-reflecting sheet. This should only be done for walls that border the street.
Make a vertical sheathing. This can be a full-fledged frame, but it can also be ordinary wooden planks. The step between the slats should be made according to the ISOVER width
Lay sheets of insulation, gluing them to the wall
Attaching the moisture-repellent film
Now you need to fill the horizontal strips

Ceiling insulation

It is necessary to insulate the ceiling using practically the same technology as the walls. The only difficulty is that you have to mount it above your head.

Disadvantages of ISOVER

Even modern materials cannot be absolutely perfect. But regarding ISOVER, it can be said that its two shortcomings can be completely mitigated.

ISOVER – prickles and causes irritation. This can be avoided by wearing gloves.
ISOVER is afraid of moisture and under its influence it loses all its positive traits. This means that the material cannot be used outside (except for those types that have additional protection in the form of foil layers)

ISOVER cost

Rolled standard ISOVER, which is used for insulating walls and ceilings, has a square area of 20 m2. The thicker the sheet, the better the technical characteristics of the isover insulation, the price is correspondingly higher.

Thus, ISOVER KT 40 has a thermal conductivity class of forty, a sheet thickness of 10 cm, is classified as non-combustible material and costs 750 rubles.

ISOVER sheet, which can be used for pitched roofing, has dimensions of 100 / 1170 / 610 millimeters. The packaging area is from 14 to 17 m2 depending on the thickness of the sheet. The cost is about 800 rubles.

Isover insulation: technical characteristics and installation features

Isover insulation: technical characteristics, types of material, prices and areas of application. How to insulate walls and ceilings with it and where it is used. And

The Isover brand, known in the world since 1937, has been selling its products in Russia and the CIS for several decades. Thermal insulation Izover consists of mats, slabs and rolls of stone wool and glass wool. Today we will look at their features.

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 production of mirrors and glass. And the brand name “Isover” uses two words “insulation” and “glass”. Today in Russia the brand has two factories where insulation materials are produced. One makes materials from stone fiber, the other from fiberglass. Isover thermal insulation in Russia was previously sold under the name “Uteplyaev”.

Purpose

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

· Facades;

· Partitions;

· And other objects.

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

General characteristics of “Isover” thermal insulation

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

Main characteristics of Izover insulation:

Thermal conductivity: 0.031-0.041 W/m2*K;

Flammability: from G1 (low-flammable) to NG (non-flammable);

Vapor permeability: 0.50 - 0.55 mg/mchPa;

Service life: up to 50 years;

Air permeability is 120*10-6m3/m×s×Pa;

Thickness: from 50 millimeters.

These are only average indicators, always behind the most accurate indicators It’s worth going to the manufacturer’s official website. Below in the table we provide, as an example, more precise characteristics of lightweight insulation.

For information, we also provide a table of characteristics of Isover 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 rigidity indicators.

Mineral wool Isover includes the following products in the line:

· Facade-Master;

· Acoustic;

· Optimal;

· Standard;

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

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

Glass wool

Cheaper and more often used Izover glass wool is represented in the product line:

· Warm Roof;

· Warm walls;

· Warm house;

· Quiet house;

· Izover Classic (classic Izover);

· Pitched roof;

· Sound protection;

· Frame P;

· Frame M;

· Facade Light;

· VentFacade;

· Floating Floor;

· Sandwich Life;

· Quiet and warm roof;

· Uteplyaev (Universal, only for Siberia).

Let's pay attention to three popular types of materials:

Isover KT 37;

Isover KT 40;

Isover KT 37.

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

Isover KT 37 and 40 are 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, you need to build lathing and use materials for internal wall insulation and other interior work. Density about 15 kg per cubic meter. Sometimes you can also find the marking Isover KT Special (KT Special) - this is insulation in rolls of the same series. Below are the details in more detail.

Insulation Izover 37 and 40 technical characteristics and dimensions:

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

· Roofs;

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

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

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

There are separate types of foil material for saunas. One side of the mat is covered with foil, which prevents it from getting wet.

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

Price

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

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

Isover KL 37, 10 slabs per package, 100 mm thick slabs will also cost about 1,400 rubles.

A pitched roof, 20 slabs, each 100 mm thick, will cost 1,000 rubles.

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

Isover is a famous trademark, which specializes in the production of building materials. This is the only brand in Russia that produces thermal insulation based on basalt and fiberglass. The product range is quite wide, which opens up great opportunities in terms of insulation of both private and industrial buildings.

Description and Application

The presented material has many advantages and disadvantages of mineral wool. And this is not surprising, since their properties are quite similar. It is produced in the form of slabs, which can be either rigid or semi-rigid. There is also the opportunity to buy Izover in the form of rolls and mats. They are used in the arrangement of the roof and facades of the house, ceilings, walls and floors.

Izover is based on glass fibers, the length of which reaches 100-150 microns and the thickness of 4-5 microns. It is these parameters that allow the Izover heat insulator to obtain high levels of elasticity and resistance to loads. Competition may come from technical ones.

Specifications

Has a large number of advantages. Thanks to them, today it occupies a leading position among all other heat insulators. When choosing, pay attention to the following technical characteristics of Izover and:

Izover- This is a thermal insulation material, so it is characterized by low thermal conductivity - 0.038.

Excellent sound insulation performance.

For the manufacture of insulation, fiberglass was used, which is not susceptible to bacterial or fungal infection. It is not affected by rodents and small insects.

High moisture permeability. This indicator is a disadvantage. This is explained by the fact that the material has a porous structure.

Small specific gravity – 13 kg/m3. Thanks to the small one, the process of installation, transportation and loading of material is simplified. Installation of insulation can be done with your own hands.

Ecological cleanliness.

High degree of durability from negative influence chemical substances.

High ductility. Mats can be compressed up to 60%, and rolls up to 75%.

Fire resistance.

The video shows the technical characteristics of Izover insulation:

If we talk about the size of the Izover material, it depends on the form of release. The thickness of the mat rolls can be 5.10 cm - single-layer option. And for a two-layer, the thickness of one layer is 5 cm. For roll type standard width is 120 cm, and the length is 7-14 cm. But the area covered can vary between 16-20 m2.

But what kind of insulation should be used under a ventilated facade is described in this article:

Varieties
