Eco-friendly, efficient, durable, for all types of structures - these are the insulation materials produced by the Isover company in recognizable yellow packaging. Like the price range, the range of its insulating materials is quite wide. Under the Isover brand they produce insulation based on quartz and basalt for various types of facades, ceilings, roofs, and partitions. The right product can be found for both private housing construction and serial construction.
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.
Calculation
The main requirement for profitable and reliable sound insulation is correct calculation. Using laser measuring equipment, you can make calculations with maximum accuracy so as not to buy extra material. Of course, if you don’t have any skills or knowledge, then it’s better to entrust it to specialists who will calculate everything quickly and efficiently.

You can carry out soundproofing with isover yourself if you have an understanding of the product and how to install it. As for the choice of sizes, it is necessary to select based on the characteristics of not only the room, but also the insulating layer. If possible, then for installation work it is better to invite a professional who, in just a few minutes, will make calculations on the thermal and sound insulation qualities of the house and the insulation itself.
Interesting! Many people believe that to obtain effective and reliable sound insulation, you need slabs or rolled sheets of large thickness. In fact, everything is not so radical. Despite the large selection of materials, it is worth taking a product with a thickness of no more than 10 centimeters. This is exactly what is needed to create comfortable conditions.
The same amount of material is selected depending on the size of the surface to be treated. It is important to take into account that during installation the slabs should not be pressed in too much. They should fit snugly, but you also don't want them to fall out. If the width of the soundproofing slab is 60 centimeters, then the distance between the logs or structural elements will be 56-58 millimeters.
Important! Not only the effectiveness of the insulation, but also the cost of soundproofing the house depends on the correctness of the calculation. There is no need to save on heat and sound insulation, because convenience and comfort inside an apartment or house depend on this.
Specifications
The material obtained by the method described above has unique properties. The layers have high elasticity, low thermal conductivity (0.041), and low weight. For insulation materials, these characteristics are very important. If installed correctly, the technical characteristics do not change over time, which ensures maximum heat savings throughout the entire operation of a residential or industrial building.

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.

If you want to express gratitude, add a clarification or objection, or ask the author something, add a comment or say thank you!
Existing varieties and scope of application
The French concern Saint-Gobain produces various types of insulation materials. Nine types of isover are most popular on the Russian market:
- Thermal insulation isover KL 34 - unpressed slabs that have a very wide range of applications, used for insulation of any vertical and horizontal surfaces . A wooden sheathing is constructed for installation . The plates are inserted inside it without additional fastening.
- Isover KL 37 – pressed boards packed in packaging . They are used for insulating floors between two adjacent floors , internal walls and roof slopes .
Important! When installing the plates, they must be pressed tightly against each other.
Scope of use of different types of isover Source www.tproekt.com
- Isover KT 37 – roll thermal insulation. Used for insulating horizontal surfaces. Izover of this form can also be installed on walls, but only if it is necessary to insulate internal partitions .
- Isover KT 40 – two-layer rolls used for ceiling and floor .
- Isover "STYROFOAM" 300 A expanded polystyrene has been added to its structure . These are plates of increased rigidity . They are attached to the surface using plastic dowels or special adhesives based on bitumen mastics.

Recommendations for working with the material
Carrying out work requires compliance with safety regulations. To minimize the occurrence of traumatic situations, always wear protective clothing, gloves and a respirator.
Considering the installation process, there are practically no differences from the installation of other types of thermal insulation materials.
- Prepare the surface. This stage involves cleaning the installation site from large and small debris.
- Install the frame. If the walls are insulated, then initially it is necessary to assemble the sheathing. In the case of a roof, the rafter system will serve as the frame.
- Maintaining a pitch between the beams of 600 millimeters makes the fit of the insulation to the sheathing as tight as possible. When laying the rolls, leave a small allowance of about 2 centimeters, which will eliminate the need for fastening.
- Products of the same brand can be used as vapor and waterproofing.
- Ventilation gap. In all types of sheathing, installation of a ventilation gap is required. The exception is floor insulation.
Ventilation gap
- Before installing the facing covering, make sure that there is a gap of a couple of centimeters between the insulation and the finishing coating. This will ensure sufficient air exchange.
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.
Peculiarities
Izover insulation has some features:
- The material has good thermal conductivity. If we consider the Isover product line, the warmest one based on quartz is Isover “Warm Walls”, and among basalt insulation products - Isover “Master of Warm Walls”.
- Soundproofing qualities. The dense weave of fibers prevents noise vibrations from penetrating through the thickness of mineral wool. The main obstacle to the penetration of sound is the air that fills the voids between the fibers.
- Any Isover model is considered completely non-flammable. This feature allows the use of this thermal layer in rooms of any type.
- Vapor permeability. This quality of mineral wool is at a low level. In rooms with high humidity, Isover insulation quickly becomes saturated with moisture, losing some of its thermal insulation qualities. To provide protection to the product, a vapor barrier is initially laid, after which the installation of mineral wool is allowed. The gap between the front trim and the outer layer of insulation provides additional protection.
- Durable. Having installed Izover insulation once, you can forget about re-installation for 50 years or more. The material owes this feature to its structure.
- Environmentally friendly. Scientists have repeatedly conducted studies to identify side effects on human health from insulation, but so far no such effects have been found.
