What is isover

Isover is a material that is used to insulate flat surfaces. It is produced by French. The name of the insulation comes from two French words “isolation” - insulation and “verre” - glass. It explains what it is made of. There are two forms of French insulation on the domestic market. There are slabs and rolls. They are formed using fiberglass and basalt wool. Each variety has its own technical characteristics. They determine the scope of use.

The basis of the material is fiberglass and basalt wool. When making slabs or rolls, recycled soda, limestone and sand are added. The use of recycled materials allows us to reduce the cost of the finished product, so French insulation has a very affordable price.

The manufacturing technology of isover is extremely simple:

• The listed components of recyclable materials are mixed together, other minerals are added , the mixture is heated to 1300C and converted into a plastic mass similar to liquid glass .
• It is poured into the reservoir . microscopic holes in its walls .
• The container spins like a drum and rotates at high speed . Centrifugal force forces the loaded substance through microscopic holes. In this way, the finest threads are formed .
• The threads are mixed with a special adhesive composition . A viscous mass is formed.
• She goes into the drying oven .
• There the workpiece passes through the rollers . With their help, a layer is formed .
• At the final stage, it is cut into the required sizes . The maximum possible dimensions are 610x1170 mm, the thickness of the slab can vary from 5 to 10 cm.

Air bubbles remain between the fibers. They prevent sound penetration. Therefore, using isover for insulation, you can significantly improve the sound insulation of a building. The manufacturer recommends using this material where it is necessary to increase sound insulation without increasing the load on existing surfaces.

The slabs can additionally be treated with water repellents. They make the insulation surface waterproof. When burning, isover does not contribute to the spread of fire; the material has low smoke-generating ability.

On a note! Isover is ideal for insulating log structures, frame or panel houses.

When packaging, the mats are pressed. As a result, their volume is reduced by 60%. This greatly facilitates the transportation of insulation. After removing the packaging, the mats easily restore their shape. They can be used for external and internal decoration. During operation, no hazardous chemical elements are released from the surface of the isover. No formaldehyde or resins are used in its production. Therefore, the material described belongs to the class of environmentally friendly.

Characteristics

Isover is designed and made using special technology, and therefore has a wide range of applications. The main characteristics of the material will ensure long-term and reliable thermal insulation in various insulation systems.

They are made using steel and reinforcement. The material is also used with fiberglass. It reduces the possibility of cold penetration from outside . The main areas of application are:

1. Walls.
2. Attics.
3. Roofs.
4. Layered masonry.

The basalt slab has a density of 50 kilograms per cubic meter. When used, cotton wool shrinks by only 8%, and then regains its original volume. The product practically does not absorb water , and therefore is used in rooms with high humidity. The material does not burn . The board contains only 0.3% organic matter .

The thermal conductivity coefficient at 10 C makes it possible to use the substance for insulating foundations, wells, ventilated facades and other systems.

If Isover is placed in water for a day, it will absorb only a small amount of moisture, which is equal to one kilogram per square meter. This is about 1.5% , which is considered a high figure.

A special feature of cotton wool is that it does not burn, but melts at temperatures above 100 degrees. Therefore, it is often used in places where, in addition to thermal insulation, it is necessary to create a non-flammable layer.

Video description

The video shows the technology of insulating the walls of a frame house with isover:

Technology for installing isover on the side of the building facade

The sheathing is constructed in increments of a centimeter narrower than the width of the insulation. The slabs are laid inside, and a counter-lattice is attached on top. It should provide an air gap. A waterproof and windproof membrane is attached to it. And the finishing decorative trim (siding or lining) is already attached to it.

Soundproofing technique using isover

To soundproof the lower surfaces, floating floor technology is used. It helps reduce indoor noise levels by 50%. It is called so because the materials used for finishing do not come into close contact with the side walls. Therefore, noise waves are not transmitted to them.

To build such a structure, a layer of vapor barrier is first spread on a reinforced concrete base, then an isover is laid on it. Waterproofing material is spread on top. The top of such a cake can be filled with concrete screed or covered with gypsum sheets. Even before starting work, damper tape must be glued to the walls along the entire perimeter of the floor. It will ensure the formation of a technological gap that will not allow noise to move across the floors. The width of the tape should exceed the thickness of the screed by 2-3 cm.
