"Izover": features and technical characteristics of 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 is a trademark of the world-famous concern “Saint-Gobain”, which has been supplying its products to the domestic market for 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.

Installation features

When working with the material, you must use gloves.
When working with Izover material, remember - this is glass wool. Despite the application of additional protective coatings to the surface of certain types, the spread of glass dust cannot be ruled out. Contact with skin will cause only temporary irritation, but contact with eyes or respiratory tract will be a serious problem. Therefore, the use of gloves, masks, respirators, and safety glasses when working with mineral wool is mandatory.

Laying Isover stone wool is a simple, quick and almost waste-free procedure. Installation between the joists inside the interfloor ceiling is carried out without the use of additional means of fixation. Sloped roof structures also usually do not require the use of dowels or strings. Vertical installation of rolls can cause some difficulties, so it is not advisable. The slabs are installed in partitions between profiles or sheathing bars, mounted so that the insulation fits as tightly as possible. As a rule, the width between the posts equal to the width of the slab minus 1 cm is quite sufficient. Installation of facade samples is carried out using disc-shaped dowels or special glue.

Conclusion

In conclusion, I can say that the price of this material is consistent with its high performance properties. You can once again verify this by watching the video in this article . If you have any questions regarding its use or, conversely, you want to share your own experience, please write about it in the comments to the article.

Insulation release form

There are also single-layer and two-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, quite large in size. 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.

How it is made

So, what is Isover insulation? The characteristics of any insulating material depend primarily on how accurately the required technologies are followed during its production. Isover insulation is manufactured as follows:

• Quartz sand, cullet, limestone, soda ash and other minerals are thoroughly mixed in advance.

The resulting mixture melts at a temperature of 1300 degrees. until a homogeneous fluid plastic mass is obtained. In a special installation, this liquid glass is fed from a great height into a bowl rotating at high speed, the walls of which have small holes. Under the influence of centrifugal force, the hot mass is squeezed out in the form of long thin threads. The fibers are mixed with yellow polymer glue. The resulting sticky mass is fed into a special oven, where it is rolled between steel shafts and blown with hot air. As a result, the glue sets and the layer itself is leveled. The finished glass wool is fed into circulation saws to be cut into slabs of the required size.

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. It appeared at the direction of 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. The company is included in the following ratings:

1. The hundred largest industrial enterprises according to Forbes.
2. Top 100 innovative organizations in the construction sector.
3. Best Employer - 2016

Experience and the latest technologies have made the company a world leader in creating a comfortable living space. The main activities of Saint-Gobain are:

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 EN 13162—ISO 9001.

Key insulation indicators

Isover is an insulation material that is made from fiberglass of the best quality using a special technology. It is in many ways similar in its properties to mineral wool. Available in:

• rigid and semi-rigid slabs;
• rolls and mats.

The latter are used in the arrangement of building facades, ceilings and for roof insulation. The basis for Izover is glass fibers. Their indicators:

• length varies from 100 to 150 microns;
• thickness is 4 to 5 microns.

Due to the above parameters, the insulation is characterized by resistance to various types of loads and elasticity.

Thermal conductivity indicators

The thermal conductivity coefficient is not so high and is only 0.041 watts per meter per Kelvin. Moreover, this value does not change upward over time, as happens with some other heat insulators. Thus, glass fibers are able to conserve heat and retain air.

Sound insulation parameters

Fiberglass material has good performance in terms of protection from external noise. This is due to the fact that there is an air gap between the layers of material. It is she who is responsible for delaying extraneous sounds. Silence in the room where Izover was applied was ensured.

Prone to fire

Any thermal insulation materials whose density reaches 30 kg per cubic meter and are called Isover are classified as non-flammable. This is their definition, in accordance with GOST standards. This insulation can be used in any home, including residential ones. Izover's characteristics allow this to be done. Its use is considered safe both for insulating a one-story cottage and a high-rise building.

Rigid and semi-rigid modifications, equipped with a coating of Tyvek film, fiberglass or aluminum foil, are considered low-flammable. There are some restrictions for such insulation, but there are relatively few of them. Accordingly, they can be used almost everywhere. The main requirement concerns strict compliance with fire safety standards in the building, which form the basis of SNiP.

Vapor permeability of Izover

For most modern thermal insulators, resistance to moisture is the main disadvantage. Most of them cope with their functions, as long as the air in the room is dry. Once it gets wet, even fiberglass can retain heat less well. But Izover is good because it is able to both quickly absorb moisture and quickly release it back.

For this rule to always work and under any conditions, it is necessary to leave a gap between the insulation and the wall, the diameter of which would be at least 2 cm. It is necessary for optimal ventilation. If you forget about this point, then the thermal insulation characteristics of Izover will begin to decrease as moisture accumulates. Its vapor permeability varies from 0.50 to 0.55 mg/mchPa. If the insulation receives 1% moisture, then the thermal insulation performance will drop by 10%.

Duration of service

Isover is an insulation material for which service life is one of the key indicators. Even if it is able to retain heat for a long time, it can last no more than a year. It all depends on the specific product. Insulating a building requires a lot of effort and time. Yes, and this requires a lot of work.

Fortunately, Izover is an exception to the rule. By using it to cover the floor and walls, you can forget for a long time about the need to re-install it. There are examples when it was possible to use a heat insulator for several decades in such a way that all its indicators remained unchanged.

The so-called water repellents included in Izover have water-repellent properties. In addition, insects and other pests do not settle in this insulation, since they simply do not like such a habitat. Even mold does not attack fiberglass insulation.

Environmental performance and safety

Izover can boast not only of its technical characteristics. Any fiberglass materials of this type are considered harmful to human health. It does not include any toxic compounds. Finnish scientists spent a long time checking the parameters of the material and came to the conclusion that its use, even over a long period of time, does not negatively affect people’s quality of life.

Product weight

Isover is much lighter than other heat insulators. That is why in those structures where the walls are not made of the most durable materials or the excessive load is unacceptable, it becomes a way out.

Advantages and disadvantages

Advantages:

• Effective heat conservation.
• Insulation of any part of the building.
• Possibility of creating a noise-insulating layer. The sound transmission capacity is reduced when laying a 100mm double covering.
• The tight fit of the Isover insulation eliminates the need to use fasteners.
• The ability to compress is perfectly reflected in the transportation of products.
• Environmentally friendly.
• Isover thermal insulation is made using components that are not prone to fire. This is the reason to consider mineral wool non-flammable.
• It is resistant to fungus and mold.

Flaws:

• Isover is expensive.
• Use is not recommended when there is a high load on the surface of the insulation.
• Without wearing protective clothing, insulation can cause trouble to human health.

Material Specifications

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

1. High thermal conductivity: 0.033-0.037 W/mK.
2. Flammability class NG: does not ignite and does not support combustion.
3. Wide operating temperature range: withstands heat up to 6,000 degrees without deformation.
4. Density: about 15 kg/m2.
5. 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.

All products have international environmental certificates and comply not only with internal corporate standards, but also EN 13162—ISO 9001.

Isover (Egoryevsk, Chelyabinsk)

More than 20 years ago, the French concern Saint Gobain officially opened the Russian building materials market. Over the past 10 years, the company's management has abandoned the import of mineral wool to Russia and opened its own production of products under the Isover brand in the Moscow region. Today, there are two full-cycle production sites in the Russian Federation - in Yegoryevsk and Chelyabinsk.

Isover mineral wool is suitable for ventilated facades and under plaster; for pitched and flat roofs; into internal partitions and doors. The materials are developed in accordance with the operational features and installation specifics for each specified case. The company's catalog presents four main groups:

• Isover warm – thermal insulation;
• Isover quiet - Shumka;
• Isover professional – universal insulation;
• Isover for a house/apartment - mineral wool with a compromise combination of cost and performance.

The list offers 24 insulating material options.

All plate, roll and blown-in wool versions are packaged in heat-shrinkable polyethylene. This makes it possible to reduce the volume of insulation ready for shipment by 3-5 times (relevant for more efficient transportation).

The positive aspects of Isover are the variety of options. Can be made to your size. Among the existing advantages, the ease of use when filling hard-to-reach areas with blow-in cotton wool stands out.

The downside is the need to use highly specialized equipment (true only for the blown-in version of mineral wool).

Types of thermal insulation

All materials produced under the Isover 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 is a mineral plate 5 or 10 centimeters thick. It is used in 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 state – 98%.

Thermal insulation of walls and floors:

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 its competitors - the ability to use it in conditions of 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 with partial immersion - 0.08 kg/m² in 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 in the Russian markets.
Non-combustible thermal insulation for pitched roofs Izover is sold in packages with an area of ​​14.72 m² and a weight of 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, Isover competes with Rockwool Wired Mat 80 slabs. However, the roll form of the product allows you to insulate large areas much faster with the help of a non-combustible 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.

Izover roll insulation: 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 house construction.
3. Acoustic - for sound insulation.
4. Floor - from impact noise.
5. Ruf V, Ruf N - for flat roofing.
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:

Using wool of different densities for insulation

The choice of insulation according to the indicator under consideration depends on the place of its use. It is not always necessary to overpay in order to get the desired result. Most often, the facade, walls, roof and floor are insulated. These are the options that are worth considering.

Facade

When selecting insulation for a facade, you need to pay attention to the mass and density of mineral wool. For most buildings, weighting is very undesirable. It is also worth paying attention to the possibility of subsequent finishing, because this indicator is also influenced by

So:

It is also worth paying attention to the possibility of subsequent finishing, because this indicator also affects this. So:

• If the facade is equipped with a ventilated one, then a sufficient density is 45-100 kg m³. Here the cotton wool is laid into the sheathing and there will be virtually no stress. The main tasks for this type are to maintain its shape and not sag under its own weight, and the indicated indicator is enough for this.
• If the facade is to be plastered over insulation, then the density should be above 100 kg m³, optimally from 145 to 165. This will allow the use of any types of plaster mixtures, including bark beetle, barenkom and even mosaics. Since this mineral wool will have to withstand heavy loads during installation, it must be securely fastened; for this, a system with dowels is used in combination with adhesive fastening.

Wall insulation

In this case, the selection is made based on ease of installation, that is, the density should be at least 30-45 kg m³. In this case, you need to insulate from the inside; MDF boards or drywall should be screwed onto the material on top. In order to mount such mineral wool, you need a lathing; rolls or sheets are placed in it.

Roof

Since roof insulation work is carried out at heights, the main criteria when selecting mineral wool are light weight and ease of use. Material with a density of 30-35 kg m³ can be pleased with these qualities. Its sound and heat insulation properties will be excellent, and at the same time light weight. Installation can be carried out using two methods:

• Using a construction stapler.
• In the lathing with a vapor barrier closure.

In both the first and second cases, it is necessary to cover the insulation with finishing material on top.

The selection of mineral wool in this case depends on the type of floor finishing. So, if these are sheet materials, for example solid boards, laminate, etc., then a density of more than 30-45 kg m³ is not needed. After all, there will be no pressure on the cotton wool; it is placed between the lags.

But now manufacturers offer material with an indicator of 200-220 kg m³; such wool can be mounted on the base and filled with cement screed on top. Of course, the price of such material is quite high, but the ease of handling is the greatest possible.

Characteristics of Izover insulation

Let's look at what this heat insulator is. First of all, the quality of any thermal insulation material depends on the accuracy of adherence to manufacturing technology at each stage of production. The production of Izover is carried out in several stages, each of which is carefully controlled.

Provided that all technological standards are observed during manufacturing, Izover insulation has the following basic qualities:

Thermal conductivity

For Isover, the thermal conductivity coefficient is 0.041 watts per meter per Kelvin. In addition to the fact that this value is more than acceptable, it is noteworthy that it practically does not increase over the entire service life of the insulation. This is due to the fact that strong fiberglass is less susceptible to destruction and reliably retains air.

Soundproofing

Using Izover as a soundproofing material can effectively protect a room from extraneous noise and sounds. Like all fiberglass insulators, Izover perfectly retains air inside, which destroys sound waves, and taking into account specially developed modifications, the sound insulation of rooms treated with insulation meets all existing standards.

Flammability

Thermal insulating materials with a density of up to 30 kg US3 and called Isover are not considered flammable. This is how they are designated by special GOST 30244-94, which assigns them the abbreviation NG. Thus, the use of Izover insulation from the point of view of fire safety is absolutely safe both for industrial construction and for private households.

As for Izover sheet insulation, according to the technical characteristics, the above GOST defines them as slightly flammable. This definition suggests that such insulation can be used in industrial and civil construction, for insulation and sound insulation of most buildings and structures, with the exception of objects with a high fire hazard.

Vapor permeability

The ability to maintain heat and sound insulation parameters in conditions of high humidity is characterized by the vapor permeability of the insulation. For Isover, this coefficient is 0.5-0.55, which means that with an increase in its humidity by 1%, the thermal insulation parameters can decrease by 10-12%. However, this significant drawback is characteristic of all such materials and, subject to all technological measures, it can be avoided. With proper ventilation and waterproofing, Izover will fully cope with its responsibilities.

Life time

Proper installation of heat insulation is a labor-intensive and expensive undertaking, so the service life of the insulation is very important. Due to the high mechanical strength of fiberglass, Izover is able to maintain its configuration unchanged for quite a long time

This allows the insulation to retain air, and therefore heat. With the correct ventilation and waterproofing system, the service life of Izover will be 40 years or more.

Environmentally friendly and harmless

In terms of environmental safety, Izover has all possible safety certificates. Materials made using a similar technology have undergone repeated tests and the result has always remained unchanged: Izover insulation, the properties of which are given above, does not pose any danger to humans.

Weight

In terms of its weight characteristics, Izover compares favorably with its closest competitors. Its low specific gravity and high thermal insulation make it possible to successfully use it for insulation and sound insulation of non-load-bearing structures, and also significantly simplifies installation.

Release form and dimensions

To meet all the needs of the construction market, insulation can be produced as:

1. Roll type;

2. Insulation boards;

3. According to individual sizes.

The thickness of Izover insulation in one layer is 50-100mm.

The standard roll width is 1200mm, and the length can vary from 7 to 14m.

The slabs have a size of 1000x1000mm, except where otherwise specified.

Other Various Options

• Average density 13kg/m3;
• The tightness of contact with the insulated surface strongly depends on the configuration of the object.

To summarize all of the above, it can be noted that using Izover, the main characteristics of which we discussed above, is economically feasible. In addition, laying this insulation, as a rule, does not require special skills, which also allows you to save money and insulate your home yourself.

Types of isover insulation

Isover insulation has nine popular varieties:

1. Isover KL34 – slabs 5 or 10 centimeters thick, suitable for any surface;
2. Isover KL37 – slabs are produced in pressed packages;
3. Isover KT37 – roll material;
4. Isover KT40 – two-layer mats; .
5. Isover STYROFOAM 300A – solid boards with the addition of extruded polystyrene foam;
6. Isover VENTITERM – slabs treated with a water repellent;
7. Isover “Pitched roof” – used for roof insulation;
8. Isover “Ventfacade” – two-layer facade slabs;
9. Isover “Sound Protection” – available in the form of plates and rolls, used for sound insulation.

Many types of insulation can be interchanged with each other.

Application of isover insulation

Izover is used for insulation of internal and external walls, roofs, floors of residential, public and industrial buildings. It is also used to minimize noise in wall, ceiling and floor structures.

Isover KL34 is used for any surfaces: horizontal, vertical, with any angle of inclination. To install the slabs, a frame is used in which the isover is mounted, and no additional fastenings are needed.

Isover KL37 is used for interfloor slabs, walls and roof slopes. Available in the form of pressed slabs and packaged. This type of insulation must be pressed tightly against the working surface; installation does not require additional fasteners.

Isover KT37 is produced in roll form, used mainly for horizontal surfaces, but can be used for internal walls and partitions and roof insulation. The material does not require additional fastenings; it must be pressed tightly to the surface.

Isover KT40 is a two-layer roll material used for horizontal surfaces. During installation it does not require additional fastenings.

Isover STYROFOAM 300A has improved thermal insulation and moisture resistance properties thanks to additives in the form of extruded polystyrene foam. The material is produced in the form of rigid slabs and requires additional fastenings. Depending on the base, the slabs are fastened with: plastic dowels, special mastics based on cold bitumen, or polyurethane foam glue.

Isover VENTITERM is produced in the form of dense slabs and is used for external insulation of facades, ventilation and water supply pipes, for sound and thermal insulation of ventilated facades.

Isover VENTITERM PLUS is available in slabs with the same dimensions as Isover VENTITERM. The main difference is the improved helicopter protection properties, due to the fact that on one side these plates are covered with special fiberglass.

Isover “Pitched roofing” is used for structures with changes in humidity conditions. It is also a good sound and heat insulator, used in any climatic conditions. It is used for pitched roofing and soundproofing of internal walls and partitions. The dimensions of the Isover “Pitched Roof” slab are 610x1170 with a thickness of 100 mm.

Isover “Ventfacade” is available in the form of slabs of different sizes, with a thickness of 50, 100, 150 mm. Consists of two layers, but can be used as a single layer material. Thanks to its elasticity and elasticity, it fits tightly to the base and does not require additional fastenings.

Isover “Sound Protection” is produced in the form of slabs with dimensions 610×1170 and a thickness of 50 mm. This material reduces noise levels and is used for sound insulation of roofs, facade walls, internal walls and partitions. Can be used in any climatic conditions.

Description

The structure of mineral wool is fibrous. Natural minerals are used in production: sand, limestone and soda. When exposed to heat, the finest threads are drawn from the mineral components. They turn out thin and light. Subsequently, the fibers are made into mats or rolls that act as thermal insulation material Isover “Classic”. To give the mats elasticity and density, binding components of synthetic origin are added to it. For example, it could be polyurethane, the content of which in Isover mineral wool is small.

Installation of thermal insulation, to facilitate the execution of tasks, provides two options for finished products - mats and rolls. Regardless of the type chosen, the weight of the material allows you to carry out insulation yourself.

After compression, Izover mineral wool is able to take its original shape without loss of quality. This property is well used by manufacturers for economical transportation. The insulation is rolled up by compression, decreasing in size up to 6 times. Thanks to this packaging method, it is possible to save more free space for stacking additional product packages.
