The building materials market constantly offers new types of products for home insulation. One brand that can meet the needs of any type of thermal insulation is Izover. The characteristics allow the widespread use of slabs or mats of this brand throughout our country. The company's products are widely used in private households, industry and when laying communications.

Cooperation between the Russian market and Saint-Gobail began 25 years ago

Brand history

The rights to the brand belong to the Saint-Gobain company from France. Its main office is located in Paris, and its founding date is 1665. She appeared on instructions Louis XIV and produced glass and mirrors. The name Isover insulation is formed from the words “glass” and “insulation”. In our country, the company's products were initially known under the Uteplyaev brand.


Initial Izover products in Russia

Over more than 350 years of history, Saint-Gobain has grown into an international industrial group represented in 67 countries and employing over 170 thousand employees. Sales in 2015 amounted to 39.6 billion euros.

  3. Distribution activities in the field of building materials.

Saint Gobain Campaign:

The company's products have been known on the Russian market for more than 20 years. Ten years ago, a plant was opened in the Moscow region (Egoryevsk), and since 2011 in Chelyabinsk, the Minvata company began producing stone fiber insulation. All products have international environmental certificates and comply not only with internal corporate standards, but also with EN 13162-ISO 9001.

Scope and properties

Isover thermal insulation can be purchased in rolls and in slabs. This is a non-flammable material with excellent properties. The company is not a monopolist in its segment. It competes with mineral insulation materials Ursa, Rockwool, Izovol, Knauf and Parok.


The company's material is perfect for insulating and soundproofing your home

Isover mineral wool is widely used for the following types works:

    1. Sound insulation and insulation of wall structures and roofs.
    2. Arrangement of ventilated facades and multilayer partitions.
    3. Installation of pipelines and other communications.
  1. The industry uses one of the varieties of the brand - Isotec.

In order to get high-quality results when using similar material, before purchasing, you need to understand the technical characteristics of Izover insulation. This is fiberglass-based mineral wool, manufactured using TEL technology.

Does density matter? thermal insulation materials:

Main indicators:

  1. Thermal conductivity is 0.041 W×m−1×K−1, which allows you to retain air without changing properties in different climatic zones.
  2. Maximum sound protection is achieved due to the porous structure of the material.
  3. Average density - 13 kg/m³. Depending on the type of insulation, it may vary slightly in one direction or another.
  4. Fire safety is explained by the low previous indicator, which guarantees the absolute non-flammability of the product. Therefore, the use of Izover is permitted in commercial and residential premises, cottages and apartments in high-rise buildings. Foil plates are low flammable. The main condition will be full compliance fire safety standards when laying material and operating the structure.

Main indicators of Izover mineral wool:

  1. The problem with modern insulation is the formation of condensation inside the layers. Fiberglass solutions have special water-repellent components. They help remove moisture and increase vapor permeability. For Izover it is 0.5-0.55 mg/mPa. When installing, it is recommended to leave a two-centimeter gap from the wall.
  2. Depending on the type and conditions of use, mineral wool from Saint-Gobain can last from 50 to 100 years.
  3. The absence of harmful emissions during operation guarantees the environmental purity of the insulation.
  4. Low weight, the lowest in its segment, allows this building material to be used even in weak load-bearing structures.
  5. The dimensions of the slabs and rolls allow the use of insulation with maximum rationality.

Advantages of Izover material:

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.

  1. Tolerance of extreme temperatures.
  2. Fire safety.
  3. Immunity to deformation.
  4. Ease of peeling.
  5. Tensile strength.
  6. Waterproof.
  7. High level of noise absorption.

Pros and cons of isover insulation:

When working with Isover products, you must adhere to the following precautions:

  1. Restrict access to the construction site during work.
  2. Use film, plywood or gypsum fiber board as fencing.
  3. Use personal protective equipment: overalls, goggles, respirators.

Preparation method

In order to achieve necessary qualities During production, all required technological standards and processes must be observed. Make Izover this way:

  1. A mixture is prepared from quartz sand, soda ash, limestone, glass waste and other minerals.
  2. This composition melts at a temperature of about 1300 degrees. The result is a homogeneous plastic mass.
  3. Next, 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 influence of centrifugal force.
  4. Mixed with polymer yellow glue, a sticky substance is obtained, which enters the oven for rolling and drying.
  5. The set layers are cut into the required formats with a circular saw.

Production of Izover insulation:

Types of thermal insulation

All materials produced under the Izover brand differ from each other in functional purpose and physical properties. Industrial and household categories of insulation are supplied separately. There are several of the most popular varieties of products from Saint-Gobain.

Types of thermal insulation Izover:

Minvata Izover KL 34

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

The insulation is packaged in a bag. After opening, it instantly takes on its original appearance and is ready for installation. Another advantage of this modification is low shrinkage. Among the technical characteristics it should be noted:

  1. Thermal conductivity – 0.034 W/μ.
  2. Vapor permeability – 0.53 mg/mchPa.
  3. Nominal compression at 2 thousand Pa – 60%.
  4. Return to normal condition – 98%.

Thermal insulation of walls and floors:

This material is completely non-flammable with operating temperatures from -70 to +250 degrees. If it is completely immersed in water, 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 roof insulation. Available in the form of mats measuring 117x61 centimeters and 5-10 cm thick. It is almost one hundred percent hydrophobic. This is its main advantage over competitors - the ability to use in conditions high humidity without loss of properties.

This type of Izover product is characterized by the following indicators:

  1. Thermal conductivity - 0.035 W/mK.
  2. Steam conductivity - 0.55 mg/mchPa.
  3. Absorbency when partially immersed - 0.08 kg/m² for 25 hours.
  4. A density of 15 kg/m³ is combined with sufficient return and deformation properties.

The advantages of the material make it number 1 on Russian markets

Non-combustible thermal insulation For pitched roofs Isover is sold in packages measuring 14.72 m² and weighing 10.8 kg.

Product category KT37

This insulation is available in rolls 630 cm long, 60 cm wide and 50 or 100 millimeters thick. Double compression packaging allows for convenient and economical transportation of the material to the construction site. If the volume of insulation in the package is 0.16 cubic meters, then after opening it increases to 0.71 m³. The scope of its application is the insulation of concrete, brick, and wooden buildings from the inside. It is not prohibited to install floors and interfloor ceilings as thermal protection.

Due to the density of 15 kg/m³, it is not recommended to use KT37 in structures with high mechanical loads. Thermal conductivity of 37 W/μ is sufficient to create an effective coating even in one layer. In this regard, Isover competes with Rockwool Wired Mat 80 slabs. However, the roll form of the release allows you to insulate large areas much faster with the help of a non-flammable product from Saint-Gobain.

Roof insulation:

Material indexed KT40

It is classified as wall insulation. Isover KT40 is supplied in rolls and is intended for frame, brick houses and for insulating free building cavities. The roller, which is 10 cm thick, can be easily divided in half thanks to its two-layer structure. Its remaining dimensions are: 7 meters in length and 61 cm in width. Covered area - 17.8 m².

Roll insulation Izover:

Its thermal insulation properties are slightly worse than those of other Izover materials - 0.04 W/mk. However, high vapor permeability (0.5 Mg/mPa) makes it possible to effectively insulate buildings made from any raw material with its help. To improve moisture absorption, which amounts to 15% of the weight of the product, it is recommended to install additional waterproofing. GOST 30225 classifies KT40 as non-combustible thermal insulation.

Basalt mass

Russian factories, in addition to fiberglass slabs, produce materials in the form of stone wool. Similar varieties have the following differences:

  1. Higher cost.
  2. More durable, stronger and denser than traditional mineral wool.
  3. Less elasticity. Packages are larger, increasing the cost of storage and transportation.
  4. High moisture and heat resistance.

Basalt insulation is more expensive, but of the highest quality

Classification of basalt insulation:

  1. Optimal - for pitched roofs in the form of sound and thermal protection.
  2. Light - for frame housing construction.
  3. Acoustic - for sound insulation.
  4. Floor - from impact noise.
  5. Ruf V, Ruf N - for flat roof.
  6. Plaster and Facade-Master are designed for facades under plaster.
  7. Venti - with improved vapor permeability.
  8. The standard applies to multi-layer brickwork.

Testing basalt wool for combustion:

Installation of thermal protection

A wide range of uses implies several options for working with Izover materials. There are 4 technological options in total:

  1. Metal frame structure.
  2. Wooden building.
  3. Using staples.
  4. On the plinth.

When installing thermal protection, seek help from a specialist

When assembling the thermal insulation complex, one should take into account physical properties materials. It is worth considering additional protection from moisture using special films. When laying a roofing or wall pie, a certain order of layers should be observed. The vapor barrier is usually stretched with inside to prevent condensation. The waterproofing is installed outside to protect against precipitation.

It is very difficult to choose the best of the many varieties of Izover products. Each type has its pros and cons. However, due to the diversity of the assortment and the optimal price-quality ratio, this product is recognized as the most popular.

All about insulation and thermal insulation Izover:

Today, construction markets are simply filled with a variety of thermal insulation materials, which differ in price, types of shapes, installation method and, of course, quality. Competing companies create new models of insulation, only to occupy the highest sales level in the construction markets. There are also materials that always remain in leading positions. One of these materials is Izover. This is an insulation that specifications achieve simply colossal quality when insulating rooms or buildings.

In terms of properties, Izover is very close to mineral wool, and also has its pros and cons. The material is produced in the form of pressed rolls with a hard and soft structure, so it is excellent for insulating roofs, building facades, ceilings and walls indoors. The basis of the Izover material are fibers that are about 100–150 microns in length and 5 microns in thickness. This quality and dimensions increase the level of elasticity and resistance to load transfer. external factors.

Technical characteristics of Izover

The Izover material is made of the highest quality fiberglass, and this is achieved by using TEL technology. Izover currently has no analogues on the construction market. Izover has the following advantages:

Technical characteristics of Izovol insulation

The technical characteristics of insulation have not only positive traits related to thermal insulation. There are also secondary advantages, such as service life, environmental friendliness and the weight of the insulation, which plays a big role during installation.

Insulation release form

In order to increase the ease of use of Izover, many companies produce the material in several forms. These can be rolls, slabs, and mats, which in their structure have different rigidity for insulating the external or internal surface of walls in buildings, and the price also differs depending on the choice of type of form.

Also distinguish single-layer and double-layer Izover. In the first case, the thickness reaches 5–10 centimeters. The two-layer material does not differ too much in thickness, since here the dimensions of one layer are about 5 centimeters. The slabs can be about a meter in size, or more precisely, this is the standard that can most often be found on the construction market, but there are exceptions when ordering insulation on websites or from dealers.

One roll of Izover insulation is about 16–20 square meters, that is, enough big sizes. The roll width reaches 1.2 meters, while its length can vary from 7 to 14 meters. It goes without saying that the technical characteristics will differ slightly depending on the choice of material size.

Varieties of Izover models

As mentioned above, the isover material has many models and this is not surprising, because its application has a fairly wide scope. Insulation can be used indoors, which means that the model will already be, it will not have such a rigid structure due to minimizing the impact of external factors, but when insulating the external surfaces of buildings, most often Izover already has a different structure. In fact there is whole list insulation models.

Model Isover KL34

Most often, this model is used when insulating the facade and masonry of a building, which has several layers at once. Distinctive feature This model is that it has a size of 5–10 centimeters in thickness, but does not require additional fasteners, and installation is carried out only on a pre-installed frame.

Model Isover KL37

This model is produced in the form of rolls that have a pressed structure. That is why the material can be used indoors, but the main thing is an almost identical installation feature. Here you also don't need to use additional fasteners, but it is important to install the insulation on the frame so that it fits well to the surface. Most often, this model is used when insulating attics in private homes.

Model Isover KL40

The KL 40 model differs in that it has two layers in its structure. Izover technical characteristics of this model allow the use of insulation for installation on horizontal surfaces, that is, it is actually most often installed as a floor or ceiling material. If the dimensions on the floor or ceiling do not allow the use of two layers of material, it can be easily separated and only one layer installed. The price of such insulation is comparatively lower than other models.

Disadvantages of using Izover

The main disadvantage of Izover insulation, which many sites are silent about, is that it goes without saying fiberglass structure, having very fine glass chips. Because of it, installing insulation is quite inconvenient and dangerous, because if a large amount of such glass dust gets into the body, unwanted problems may begin. Negative consequences for the body.

To ensure that there are no health consequences when installing insulation, you need use gloves, goggles and a respirator. Many may think that this is an unnecessary safety feature, but just look at the fiberglass under a good sunlight to see all the glass dust.

Conclusion

Isover is an excellent material that is superior in quality a large number of analogues in the modern construction market. Due to all its advantages, insulation is deservedly in first place in terms of the number of purchases and popularity.

Izover insulation










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

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

Manufacturing technology "Izover"

What is ISOVER? This is mineral wool-based insulation, which is available in rolls, slabs and soft mats. However, regardless of the shape, 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, and microscopic glass particles.

The components are mixed and heated to temperature 1 300 degrees. As a result of thermal exposure, solid components melt, turning into a viscous homogeneous mass.

The resulting composition is loaded into a special installation (centrifuge), the bowl of which rotates at enormous 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 adhesive based on polymer materials.

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

On final stage In production, the insulation is cut into strips, following the specified dimensions.

Types of thermal insulation

The ISOVER insulation line includes several items. Each type 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 out from the markings indicated on the packaging. It looks like this:

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

KL. Soft slabs designed for insulation internal partitions and ventilated facades.

AL. Insulation with this marking has a layer of aluminum foil on the surface that serves as a vapor barrier.

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

Knowing these features, you can easily select insulation to solve specific construction problems.

Scope of application of fiberglass products

“Isover” is considered a universal insulation material, therefore it is suitable for the following work:

Heat and sound insulation of external wall structures.

Arrangement of ventilated facades.

Soundproofing interior walls new partitions.

Industrial ventilation systems, pipelines.

Pros and cons of insulation that you should remember

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

TO strengths relate:

Wide range of products.

Easy to store and transport.

Long service life – up to 50 years.

Resistance to temperature changes.

Reliable heat and sound insulation.

Obvious shortcomings are considered:

Lack of environmental safety.

Dependence on external factors: perfectly absorbs moisture.

Some builders consider the soft structure of the insulation to be a disadvantage, which somewhat limits its scope of application.

Material Specifications

At optimal ratio price/quality, 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: withstands temperatures up to 6,000 degrees.

Density: about 15 kg/m2.

Moisture absorption: 0.08 kg/m per day.

It should be clarified that these are average indicators. Insulation is available in a wide range, so density and thermal conductivity may vary.

Which is better, Isover or Rockwool?

These brands of insulation are direct competitors in the construction market, so consumers are interested in which material to choose. It is immediately necessary to clarify that both insulation materials have similar characteristics, however, they are produced using different technologies.

ISOVER is a mineral wool made from glass fiber, 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 eliminates the presence of glass. Therefore, Polish products are considered more environmentally friendly.

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

This is due to the fact that non-compliance with installation technology can lead to microscopic particles of glass floating in the air of residential premises, which can have a detrimental effect on 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 insulation.

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 when performing installation.

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

Briefly about the manufacturer

As mentioned above, ISOVER is a trademark of the Saint-Gobain group of industrial companies. The company has 350 year history, the central office is in Paris. The company has representative offices in 67 countries. In addition to ISOVER, Saint-Gobain produces insulation products of the ISOROC and ISITEC brands.

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

Izover insulation: technical characteristics, photos, price

IN trade names It's easy to get lost when it comes to 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 Izover insulation, which was originally produced and developed 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. As before, this is a material based on glass fiber and mineral fibers, but thanks to localized production, the price of the material is no longer European and the quality is quite good.

What is Izover

Izover insulation technical characteristics photo the price of which will be shown below 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. These are the 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 by the simple property of air placed in 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 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 easily insulate the internal walls of residential buildings with the material, 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 when you consider the costs of lathing equipment, fastening materials and additional elements which 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 of 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, for 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 loose roll will be within 1.25 m. Universal insulation can have a thickness of up to 100 mm and is produced in the form of slabs of the same 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 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:

  1. Foil-coated isover is used for baths and saunas.
  2. Ceilings and floors are insulated with less dense material.
  3. High-density Izover is used for floors and roofs.
  4. It is used when installing plastic windows.
  5. For insulation of balconies.
  6. For insulation of basements and basements.
  7. Interior partitions are insulated taking into account the fact that the material has good sound insulation.
  8. For insulating facades.

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

What you need to know about Izover insulation. Characteristics

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.

Let's take a quick look at 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 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:

· 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 area in the line within the framework of one article, so we will summarize the approximate general characteristics of 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; you should always go to the manufacturer’s official website for the most accurate indicators. 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

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

Mineral wool Isover includes the following products in the line:

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:

· Izover Classic (classic Izover),

· Quiet and heat roof,

· Uteplyaev (Universal, only for Siberia).

Let's focus on three popular types materials:

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.

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, you need to build a sheathing and use materials for internal insulation walls 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 slabs Isover have a density of 16 kg/m3). This series is intended for insulation:

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.

For sauna there are individual species 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 GOST standards. 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 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.

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

We insulated the walls of the house stone wool Rockwool and worked without glasses or gloves. It remains to insulate one wall and there weren’t enough slabs. We decided to save money; the price for 8 slabs of 50 mm thickness was 350 rubles. Save 20 rubles on each stove when purchasing Izover. While my husband was at work, I set about installing the insulation myself. I didn’t wear any protective equipment, as before, it was tough. I cough, sneeze, itch. Covered it with film and screwed the drywall down. Even after two days the insulation still stinks. I also covered everything on top with expensive photo wallpaper... it’s a pity to take it off. But there is no choice left, when you sleep, you feel like you are breathing dust. The small child did not sleep for three nights. We took out this insulation and ordered a new one. It’s a pity, of course, for the money, I was once again convinced that it’s better to be more expensive, but just once. Hope it helps someone. Insulating the walls with Izover inside seems to me not an option at all.

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

room temperature, the stronger smell and more substances are released. It is recommended to cover the cotton wool with film on top and bottom. As my repair experience has shown, it is imperative to place it under the cotton wool, from the ceiling side. It is advisable to secure it well with a stapler. Don't forget to tape the joints - this will reduce the smell in the room. (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 are 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. I found Isover and was attracted by the low price. They wrapped the pipe, plastered it over the mesh and left it for testing over the winter. The pipes lie on the surface, so you should be able to see how the insulation works.

So, it snowed, it was +115 inside the pipe, if there had also been a plus on the plaster, a snow crust would have formed, but no, everything is fine, the pipe on top is cold.

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, 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 quite well with a regular knife.

This article presented the characteristics of Izover. We also included reviews from real consumers for an objective assessment. Conducting thermal insulation work, for example, wall insulation, you will have something to take into account regarding this brand of insulation.

Izover insulation and its technical characteristics
Isover insulation: technical characteristics. Isover insulation dimensions. Popular brands of insulation and their cost.

The Isover trademark belongs to the international corporation Saint-Gobain. This is the only brand in the country that produces materials based on fiberglass and basalt.

The brand's product line is wide and includes special solutions for private and industrial needs. The insulation has high thermal insulation qualities and is in consistently high demand. Over the 20 years of presence on the market of our country, it has won the trust of consumers and many positive reviews.

Characteristics and scope

The material is produced in slabs and rolls and is characterized by high thermal efficiency, elasticity, density and light weight. Refers to non-combustible materials.

Main competitors in the market mineral insulation- these are Ursa, Izovol, Rockwool, Parok, Knauf. Isover mineral wool has a wide range of applications in general construction work. For industrial work Izover company produces insulation under the Isotek brand.

Isover is used for the following types of work:

  • roof insulation;
  • ventilated facade systems, multi-layer walls;
  • for sound insulation of internal partitions;
  • in industry - for insulation of pipelines, ventilation, etc.

Isover, like other insulation, has its advantages and disadvantages.

The advantages of Izover include:

  1. Ease of transportation and storage - the manufacturer compresses the insulation 5-6 times when packaging it. Izover restores its shape 100%.
  2. Product lines with different technical characteristics are intended for different areas of construction. For example, Isover Sound Protection or Isover Pitched Roof.
  3. High elasticity. The insulation is superior to other mineral wool in this indicator, thanks to the special TEL technology with which it is produced.
  4. High energy efficiency - 5 cm of mineral wool is equal in thermal conductivity to 1 m of brickwork.
  5. Refers to non-combustible materials. The use of mineral wool for thermal insulation of a house does not increase its fire hazard class.
  6. Noise protection. Due to the fact that there is air between the fibers of the insulation, it does not transmit sounds well.
  7. The warranty period declared by the manufacturer is 50 years.
  8. Resistant to biological and chemical influences.
  9. Light weight – 28-60 kg/m3.
  10. Convenient to work. To insulate the surface, you just need to roll out the roll.
  11. Does not shrink during use.
  12. Environmentally friendly material. Holder of the EcoMaterial Absolute eco-label and ISO 14001:2004 international environmental management certificate.
  13. Heat resistant.
  14. High density and rigidity, which allows you to install insulation without additional fasteners.

The disadvantages of Izover include:

  1. The soft structure of wool limits its scope of application.
  2. Absorbs moisture well. A ventilation gap is required during installation. If this is not done, the cotton wool can become saturated with moisture and lose its technical characteristics, and even freeze completely in winter.

It is important to know: During installation, it is necessary to use personal protective equipment - dust from mineral wool fibers is very caustic and can cause irritation to the skin and eyes.

Stamps

Isover's lines of thermal insulating products include several dozen items and are designed to solve specific problems. They all differ in delivery form, thickness, density and size.

Basalt insulation

In addition to fiberglass slabs, under the Izover brand, they are produced based on stone fibers.

The main technical differences of basalt wool:

  • higher price.
  • basalt wool is more durable.
  • stronger and denser than glass wool.
  • less elastic, more brittle.
  • higher moisture resistance and heat resistance.
  • Available in slabs.
  • lower compression ratio means transportation is more expensive and takes up more storage space.

Expert advice: basalt insulation is recommended for use in places with higher loads, because it has higher density.

In fact, the line of this mineral wool is not much different from fiberglass-based materials:

  • Isover Optimal. Supplied in slabs of 50 and 100 mm thickness. Designed for insulation and sound protection of pitched roofs and ceilings.
  • Light. Created for frame structures, has increased elasticity. Mineral wool is supplied in slabs with thicknesses of 50 and 100 mm.
  • Acoustic. Sound absorption class "A".
  • Isover Ruf V, Ruf N. Designed for flat roofing.
  • Isover Flor. Supplied in slabs with thicknesses of 30, 40 and 50 mm. Reduces impact noise by up to 35 dB.
  • Isover Plaster. Used for plaster facades.
  • Isover Facade-Master. Used for insulation of plaster facades. The thickness of the slabs is 30, 50, 100 and 150 mm.
  • Venti. It is characterized by increased vapor permeability.
  • Isover Standard. Used in multi-layer masonry.

It is impossible to say clearly which insulation is better, stone or glass wool. Both types have advantages and disadvantages - the choice depends on the conditions of use of the insulation and the requirements for it.

Today Izover is the most popular mineral wool in the domestic building materials market. With a diverse product line, high quality And affordable price it receives the best reviews from consumers. According to many builders, it has the best price-quality ratio among its competitors.
