Isover is a well-known brand that specializes in the production of building materials... It is the only brand in Russia that produces thermal insulation based on basalt and fiberglass. The range of products is wide enough, 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. mineral wool... And this is not surprising, since their properties are quite close. It is produced in the form of plates, which can be either rigid or semi-rigid. There is also an opportunity to buy Isover in the form of rolls and mats. They are used when arranging the roof and facades of the house, ceilings, walls and floors.

Isover is based on glass fibers, the length of which reaches 100-150 microns, and the thickness is 4-5 microns. It is these parameters that allow the Isover heat insulator to obtain high elasticity and resistance to loads. The competition can be technical.

But what materials should be used to insulate the walls, the information will help to understand

Isofer is famous brand for the production of high-quality thermal insulation materials. He has a variety of products in his assortment, each of which has its own technical characteristics and field of application. But they are all united by such qualities as durability and low thermal conductivity.

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

Among the presented variety, the insulation of the ISOVER brand enjoys stable popularity. This is a trademark of 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 been formed about the insulation "Isover". Therefore, we suggest that you familiarize yourself with the features and characteristics of this material.

Manufacturing technology "Isover"

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

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

The components are mixed and heated to a temperature 1,300 degrees... As a result of thermal action, the 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 great speed. The walls of the working container have holes through which the molten substance is squeezed out, forming thin threads.

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

The mixture is re-subjected to heat treatment, at the same time leveling the seams with steel shafts.

On final stage production of insulation is cut into ribbons, following the specified dimensions.

Types of thermal insulation

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

• Classic stove.

• Pitched shape.

  Ventfasad.

  Plaster facade.

  Floating floor.

  Soundproofing.

Basic characteristics can be found in the labeling 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 boards for insulation internal partitions and ventilated facades.

AL... Insulation with this marking has a layer on the surface aluminum foil, performing the function of a vapor barrier.

KT... it roll insulation used to isolate large areas.

Knowing these features, you can easily choose a heater for solving specific construction problems.

Scope of Fiberglass Products

"Isover" is considered a universal insulation, therefore it is suitable for the following works:

Heat and sound insulation of external wall structures.

Roof insulation.

Arrangement of ventilated facades.

Soundproofing of internal wall partitions.

Industrial ventilation systems, pipelines.

Pros and cons of insulation that should be remembered

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:

A wide range of products.

Easy to store and transport.

Non-flammability.

Long service life - up to 50 years.

Resistant to temperature extremes.

Reliable heat and sound insulation.

Minimum weight.

No shrinkage.

Simple installation.

Obvious disadvantages are considered:

Lack of environmental safety.

Dependence on external factors: perfectly absorbs moisture.

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

Material specifications

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

High rates of thermal conductivity: 0.033-0.037 W / mK.

Flammability class NG: non-flammable and does not sustain combustion.

Wide operating temperature range: withstands heating up to 6,000 degrees.

Density: order 15 kg / m2.

Moisture absorption: 0.08 kg / m2 per day.

It should be clarified that these are average indicators. Insulation is available in a wide range, so the 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 give preference to. It should be clarified right away that both heaters have similar characteristics, however, they are produced using different technologies.

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

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

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

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

The subtleties of working with insulation ISOVER

When working with the material, personal protective equipment must not be neglected. Gloves and a respirator are a must when installing.

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

Briefly about the manufacturer

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

On the territory of Russia, enterprises are located in Yegoryevsk and Chelyabinsk, near Moscow. The products are manufactured according to original technology, are subject to mandatory certification of an international standard, 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.

"Isover" is a heater, the technical characteristics of which make it possible to judge it as one of the most effective materials today. It has a very wide range of applications. It is made of fiberglass and comes in the form of easy-to-install plates and mats. It is used both for insulating small private houses and high-rise buildings or industrial structures. Also, this type of insulation is very well suited for protecting water pipes and other household communication systems from the cold.

How is it made

So, what is “Izover” insulation? The characteristics of any one depend primarily on how accurately they will be observed. put technologies during its production. Insulation "Isover" is made as follows:

• Glass cullet, limestone, and other minerals are thoroughly mixed beforehand.
• The resulting mixture is melted at a temperature of 1300 gr. until a homogeneous flowing plastic mass is obtained.
• In a special installation, this liquid glass from a great height is fed onto a bowl rotating at great speed, in the walls of which there are shallow holes... Under the action 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 is set, and the layer itself is leveled.
• The finished glass wool is fed under the circular saws for cutting into slabs of the required size.

Advantages of the material

The advantages of Isover insulation (the characteristics of which will be discussed below) include, first of all:

• ease of installation;
• low degree of thermal conductivity;
• high degree of fire resistance;
• versatility;
• light weight;
• excellent soundproofing qualities;
• low cost.

Disadvantages of insulation

Of course, like any other building material, Isover slabs also have certain disadvantages. These include:

• questionable environmental safety;
• the need to use protective clothing during installation.

All fibrous materials, including Isover (whose characteristics are otherwise very good), absorb water well, which is why they lose a significant part of their heat-retaining qualities.

Scope of application

• wall insulation;
• heat and sound insulation of internal partitions;
• stone and wooden houses in a warming cake;
• wall cladding from the inside;
• insulation of floors both above and below;
• insulation of roofs in houses with residential attics and attics;
• winding pipes of communications.

Foundations are usually insulated with expanded polystyrene. When using Isover for this purpose, it is necessary to additionally arrange a very high-quality waterproofing.

"Isover": characteristics

Of course, before choosing this material for home insulation, you should find out what specific properties it has. There are several types of Isover insulator. In terms of characteristics, they all differ slightly. Materials of this brand are produced with different indicators of density and thermal conductivity.

Insulation "Isover Classic" characteristics, for example, have the following:

This type of Isover insulation is currently the most popular. Other types of insulators of this brand also have good qualities.

Supplied "Isover", the characteristics of which, thus, make it possible to judge him as in fact effective insulation, in easy-to-install plates and mats.

Installation features

The frame for "Isover" can be assembled both from a wooden bursa and from metal profile... Distance between separate elements the battens should be slightly smaller than the width of the insulation boards. This allows them to be set by surprise.

Of course, Isover, the technical characteristics of which we have described, must be protected from moisture when used as a heat or sound insulator. In order to prevent it from getting wet, steam and waterproofing films... When assembling a cake of walls or roofs, in this case, a certain order of installation of materials is observed. The vapor barrier is mounted from the side indoor spaces... Due to the temperature difference, the humidity in the rooms and in the attics is usually higher than outside. Consequently, condensation forms on the walls and ceiling. The use of a vapor barrier prevents it from getting on the insulation. It is mounted on the outside. It protects the Isover from getting wet during rain or melting snow.

As already mentioned, additional fasteners are not used when installing the plates. They are only needed when installing the material on the ceiling. In order to completely exclude them from falling out, in this case, special dowels - "fungi" are used.

Since the material is capable, albeit in small quantities, of emitting substances harmful to human health, when installing it from inside the premises, you should carefully monitor the tightness of all the seams of the final finish.

Varieties

"Isover" - insulation, the technical characteristics of which we have discussed above, is classified into several popular types. In private housing construction, as already mentioned, the material "Classic" is most often used, marked with the letter "K". It, in turn, is subdivided into:

• "Isover KL 34" - very soft boards with high heat-shielding properties, used to insulate surfaces without loads.
• "Isover KL 35" is a material with a slightly higher density. It is usually used for the same purposes as the 34th variety, that is, for walls and partitions.
• "Isover 37" is most often used for insulation of floors, roofs and ceilings.
• "Isover KT" is usually used for warming basements or attics.

Such type as "Isover Classic Plus" is also very popular. His characteristics are exactly the same as those of the usual "Classic". These two varieties differ only in thickness. "Classic", as you can see from the table, is supplied in 50 mm mats. For "Classic Plus" this figure is 100 mm. There are other varieties of Isover material for a wide variety of purposes (Isover RKL, Isover OL, etc.).

Conclusion

Thus, the insulation "Isover", the technical characteristics of which were discussed in all details in this article, is a very warm and high-quality material. You can protect your home from the cold as efficiently as possible. This, as well as the not too high cost, explains its extraordinary popularity among both private owners and small and large developers.

Minvata Isover is a thermal and soundproof insulation of the latest generation. This material is made from compositions of igneous rocks, namely from gabbro-basalt rock group. For the production of mineral wool, similar materials are also suitable. chemical composition metamorphic rocks and marls. The manufacturing process of basalt wool refers to a principle similar to volcanic activity. The furnace with a temperature of 1500 ° C accepts raw materials from which a fiery liquid like lava substance is obtained. It is this melt that plays an important role in production technology and in the production of stone fibers. The melted material is converted into threads by three methods: blowing, centrifugal-roller and centrifugal-blowing.

High-quality insulation Isover made on modern equipment meets all building codes, GOST and health care requirements. According to the requirements of GOST 4640-93 mineral wool, Isover has an acid module above 1.8. This means that Isover possesses the highest degree of water resistance, which in turn gives the material durability without exposing it to destruction. Various additives make this insulation resistant to stress and mechanical damage, as well as elastic and dense. The latter, that is, the density plays an important role in thermal insulation, it is the air layers between the ultra-thin stone fibers that prevent heat loss. The material itself is lightweight and feels warm and soft.

Technical characteristics of Isover mineral wool

Thermal conductivity

Isover resistant material not only to mechanical stress, it also has endurance to heavy loads, but also it is one hundred percent barrier to cold air while meeting the minimum level of heat transfer. Isover's thermal conductivity corresponds to a minimum index of 0.041W / mK (λA). The internal structure of the insulation helps to retain air masses acting on it from the outside. When exposed different factors it does not change the specified index, even with an abrupt change climatic conditions(low and high temperatures, high level humidity, etc.), this figure remains constant.

Soundproofing properties of Izover

Air spaces between stone basalt fibers are an excellent barrier to sound background of any origin. They drown out both high-pitched sounds and low-pitched noises. The rooms are absolutely quiet, despite the surrounding high noise background, around multi-storey buildings or country houses... With this type of heat and sound insulation in residential or public buildings located in the airport or railway station area, not a single sound is felt, except for some vibrations of the sub floor. Minvata produced at the factory according to building regulatory standards (GOST 4640-93) does not change its technical properties even after 20-50 years of operation. Over time, the material successfully removes medium, high frequency and low noise.

Density of mineral wool

The density of Isover products depends on the modification, that is, on its specific type (Isover Facade, Isover Optimal, Isover Plaster and others). The average density figure is 13 kg / m3, and highest rate density - 30 kg / m3. These figures affect the scope of application, the higher the density, the stricter the rules of application. Materials of lower density are used indoors, which do not need special requirements as a high level temperature regime or high humidity. High density products are installed in areas constantly exposed to risk (fire, flood or a sharp drop temperature regime).

Fire safety

The fire safety of mineral wool depends entirely on the density coefficient. Plates, mats or rolls with a different degree of density belong to a different class of flammability, namely: slab and roll products covered with an aluminum film with a density of 13 kg / cubic meter belong to the SG class (low combustible materials), and simple thick mats with a density of 30 kg / cubic meter correspond to the class NG (non-combustible materials). Based on these data, mineral wool is selected for insulation. high-rise buildings residential, public and industrial use... The flammability class of the insulation is taken into account at the very beginning of the design of houses, therefore, after the commissioning of the objects, cases of fire are completely excluded. The safety of residents after the commissioning of buildings insulated with Isover products is the number one task. Except for fires, builders and designers choose the type of insulation carefully and strictly according to fire safety rules.

Vapor permeability

The structure of basalt materials consists of super fine fibers, between which there are many air cushions. Special additives hold the fibers together, creating a solid structure, but at the same time the material remains breathable, which prevents the formation of condensation. The vapor permeability index is minimally low, it varies from 0.50 to 0.55 mg / mhPa. The manufacturing technology has provided for a point of quick release of moisture formed on the surface of materials. This is done through good ventilation and installation with a 2cm distance from the wall, through which the walls "breathe".

Operational period

Life time stone wool varies from 50 to 100 years. This limit of the "viability" of the material depends on many factors: on the degree of operation, on the correct installation technology, on the climate and on the structural content of walls, ceilings or floors. With poor ventilation of the insulation "pie", the operational life can be halved.
Ecological cleanliness

All Isover modification positions meet the level of environmentally friendly building materials that do not harm human health. Isover is approved by the Ministry of Health and Pediatrics. It is completely safe. It can be used for thermal insulation of civil and industrial facilities.

Izover weight

Isover mineral wool insulation is considered an airy material. It is very lightweight and easy to install. The weight of rigid or semi-rigid laid insulation does not burden its bearing structures high-rise buildings.

Dimensions of Izover

The slabs or mats are between 5cm and 10cm thick and standard size 1m x 1m. Roll material corresponds to the following parameters: width 1.2m and length from 7m to 14m.

Advantageous features

Environmental friendliness and safety during operation. The material does not cause allergies and poisoning.

Durability: 50 - 80 years of service and depends on the acidity level of basalt fibers, the higher its level, the higher the water resistance, which in turn lengthens the service life.

Does not rot and is not destroyed by rodents and insects.

Does not react to temperature extremes.

Resistance to mechanical stress.

Endurance to vertical and lateral loads.

Zero heat loss. Low coefficient of thermal conductivity is able to save 60% of the heat of the premises and save the cost of electricity and gas for additional heating.

Excellent barrier to external and internal noise. Minwata Isover is able to neutralize all noise frequencies from medium to low.
Absolute incombustibility. Stone wool products can only melt at 1000-1200 degrees Celsius.

High level of vapor permeability.

Stability of parameters. The materials look perfect, keeping their dimensions, even after 50 years of service. Cold bridges are excluded for the entire operational period.

Light weight. Thanks to this, the material is quickly assembled.

Resistance to chemicals... Mineral wool Izver is not subject to destruction by hot water supply, acidic and alkaline substances.
Isover mineral wool: modifications

Types of stone wool Isover

For the convenience of working with insulation, the following types of modifications of Isover mineral wool were created:

Areas of use

Isover mineral basalt wool is widely used in the field of thermal insulation. It is used to insulate all civil and industrial buildings. There are practically no contraindications for its use. There are 4 installation methods for installing mineral wool:

• on a metal frame,
• on a wooden frame,
• on bracket fasteners
• on the basement profile.

Choose optimal way it is necessary according to the characteristics of the product, in particular, it concerns the correct choice of its size and typical modification. And it is best to consult with the manufacturer. An incorrectly chosen method can lead to unforeseen circumstances such as rejection of a multi-layer insulation or bulging of individual areas, as well as inside the sandwich may occur air spaces and cold bridges form.

Disadvantages of mineral wool

As perfect as the tried and tested material is, there is still negative sides... As for the Isover mineral wool, we can point out the only drawback: the danger of stone dust. With direct contact, it can cause bronchial asthma or allergic dermatitis, therefore it is recommended to work with cotton in overalls, gloves and a respirator.
