Rolled insulation Izover: photo and parameters Insulation Isover - technical characteristics

Here we propose to consider what such insulation Isover, how it is made, what technical parameters does it have, and what other disadvantages do products from the French concern "Sаint-Gobain" have, and what other varieties of the presented material have become the most popular in the domestic market of building materials. videos and photos will reveal all the nuances of installing plates and rolls.

Isover - what is it? Isover is a material that is used to insulate flat-type surfaces. It is made by the French company "Sаint-Gobain". The name of the insulation comes from two words in French, and it becomes clear that it is made of glass.

There are two types of French insulation on the domestic market. There are rolls and slabs that are formed using fiberglass and basalt wool.

Each variety has certain technical parameters, and these are the ways to determine the scope. The basis of the material is basalt and fiberglass wool fibers. When creating rolls or slabs, recycled soda, sand and limestone are added.

General information

The use of secondary raw materials will reduce the cost of finished products, and therefore the French insulation has a very affordable cost.

The technology for creating such material is extremely simple:

  1. Rolled insulation Izover: photo and parameters All components from secondary raw materials, which are listed, must be mixed with each other, and the rest of the minerals are added to them, and the mixture is heated to +1300 degrees and converted into a plastic type mass, which is similar to water glass.
  2. It is poured into a tank, and there are microscopic holes in its walls.
  3. The container needs to be spun like a drum and rotated at great speed. The centrifugal force will squeeze the substance out through extremely small holes, and in this way the thinnest threads are formed.

  4. Next, the threads need to be mixed with a special adhesive, and a viscous mass appears.
  5. She is sent to the drying oven.
  6. In it, the workpiece will pass through the rollers, and through them a layer will be formed.
  7. At the final stage, it is cut into the required dimensions, and the maximum possible dimensions are 0. 61 * 1.

    17 meters, and the tiled thickness can be from 5 to 10 cm.

Now let's talk about the properties.


Technical parameters

The material obtained by the method described above has unique qualities. the formations have a high degree of elasticity, low thermal conductivity (only 0.041) and low weight.

For heaters, such characteristics are extremely important, and provided that they are correctly installed, the technical parameters do not change over time, which ensures maximum thermal savings throughout the entire life of an industrial or residential building. Air bubbles will remain between the fibers, and it is they who prevent sound from entering.For this reason, using Isover to insulate, the sound insulation of a building can be greatly improved. The manufacturer advises to use this material where it is required to increase the sound insulation without increasing the load on all surfaces that exist. Additionally, the boards can be treated with water repellents.

They help to make the insulation surface waterproof, and when burning, the material does not contribute to the spread of fire, and the material itself has a low smoke generation capacity.

Please note that Isover is ideal for thermal insulation of log-type structures, panel or frame buildings.

During packing, the mats are compressed, and as a result, their volume is reduced by 60%. This greatly facilitates the transportation of the insulation, and after removing the packaging, the mats can easily recover their shape. They can be used for interior and exterior decoration.

During operation, no hazardous chemicals are released from the surface of Izover. No resins or formaldehydes are used in its creation. For this reason, the described material can be classified as environmental and safe. Insulation, which is produced in the form of rolls, is presented in two varieties. There are two-layer and one-layer rolls on sale, and they are used to insulate the ceiling or floor.

The maximum possible roll length is 14 meters, and the standard one is 1.2 meters.

Existing types and area of ​​use

Technical characteristics of Izover insulation are different, because there are different types of insulation. On the Russian market, 9 types of Isover are most popular:

  1. Thermal insulation KL 34 - non-pressed plates, which have a very wide area of ​​use, are used to insulate various horizontal and vertical surfaces. For installation, it is required to build a wooden crate, and plates can be inserted inside it without additional special fastening.

  2. Thermal insulation KL 37 - pressed type plates, which are packed in a package. They are used to insulate floors between two adjacent floors, internal walls and roof slopes.

Please note that when installing the plates, it is necessary to press them tightly against each other.

  1. Thermal insulation KT is a roll material that is used to insulate horizontal surfaces. On the walls of Izover this type of release can also be laid, but only if it is required to insulate the internal types of partitions.

  2. Insulation KT 40 - two-layer rolls, which are used to insulate the floor and ceiling.
  3. "STYROFOAM" 300A - a material with expanded polystyrene in its structure. These are plates with a high degree of rigidity, and they are attached to the surface by means of plastic dowels or special adhesives based on bitumen mastic.
  4. Thermal insulation "VENTITERM" is a plate that is additionally treated with a water repellent. This is a new product and it is just conquering the market.

    Its sphere of use is facade insulation, which is carried out by installing two-layer or single-layer systems.

  5. Pitched roof insulation is a material that is needed to insulate the roof, improve the sound insulation of the room. It is produced in the form of plates with a size of 0. 61 * 1. 17 meters, thickness 10 cm.

    The material has a high degree of elasticity and elasticity.

  6. Sound protection - a material that is designed for sound insulation of rooms. It is produced in the form of plates with a thickness of 5 cm, it can be used in any climate zone. Through it, it is possible to improve the sound insulation of the roof, external and internal walls.
  7. Isоver "Ventfasad" is a two-layer slabs that are required for thermal insulation of ventilated facades.

The selection of French insulation also has certain disadvantages. It is imperative to take them into account when purchasing a heater. Since it contains fiberglass, it is possible to work with the material only when using protective equipment. Gloves should be worn on the hands, a jacket and long-sleeved pants on the body, glasses on the eyes, and a gauze bandage on the face as a whole. If these safety rules are ignored, any contact with rolls or mats can cause severe skin irritation.

During operation, dust may start to emit from Izover, and it will necessarily contain fiberglass particles. Their entry into the human body can provoke the development of diseases. For this reason, when performing internal insulation, it is required to cover the material before laying the finishing layer (drywall, lining) with a film for steam insulation.

Isover is not able to boast of the high strength of the mechanical type, and it cannot bear the load, therefore, incorrect installation often leads to deformation of the finish. Such defects are often used by insects and "tailed" (mice / rats) for colonization.

If the boards have not been additionally treated with water repellents, they will perfectly absorb moisture. It will stay in the inner layers for a long time, due to which the qualities of the material change. Interestingly, increasing the moisture level of the fiberglass by 1% decreases the thermal insulation by 10%.

The technology of laying the material inside the walls

With Isover roll insulation, installation is simple, and for laying mats, you need to create a crate. This can be done by means of wooden beams or metal profiles used for laying drywall sheets.

The lathing step should be 1 cm narrower than the width of the insulation. Due to their high elasticity, the boards will easily fit into the space between the two guides and fit very closely to the surface. On top of the insulation, it is imperative to cover everything with a layer of steam insulation. the film is laid with an overlap, and the joints are additionally connected with a special tape for vapor insulation. from above, this structure can be sewn up with sheets of drywall or immediately installed lining.

Isover installation technology from the building facade

Rolled insulation Izover: photo and parameters Build the battens in increments of 1 cm narrower than the width of the insulation. It is important to lay the slabs inside, attach the control lathing on top. It must provide an air gap, and a windproof and waterproof membrane is attached to it. After that, decorative trim (lining or siding) is attached to it.

Sound insulation technique with Isover

In order to sound insulation of the lower surfaces, the "floating floor" technology is used, which helps to reduce the noise level inside the room is 50%.

It is called so due to the fact that the materials used for the final finish do not come into close contact with the side-type walls.

For this reason, noise waves will not be transmitted to them. To build such a structure, a layer of steam insulation is first spread on a reinforced concrete base, and then an Isover layer is laid on it.

The waterproofing material is spread on top. From above, this cake can be poured with a concrete screed or covered with sheets of plaster.

Even before starting work, a damper tape must be glued to the walls along the entire floor perimeter. It will provide the formation of a technological type gap, which will not allow noise to move along the floors.

The tape width should be more than the thickness of the screed by a couple of cm. In the form there is a technology of floor insulation materials for thermal insulation Izover.
