Insulator Izover characteristics and technical parameters + Video

Insulating materials today are offered to consumers a great variety. More and more new types of them are entering the construction market. Manufacturers, competing with each other, are trying to improve the existing types of insulation, giving them new properties. But there are also such materials that remain unchanged, rightfully occupying leading positions in the rating. As an example, it is possible to call Izover - a heater, the technical characteristics of which allow to obtain excellent results during thermal insulation.

In principle, this material has many advantages and disadvantages of mineral wool, because their properties are very close. It is produced in the form of plates, both rigid and semi-rigid. And it is also sold in the form of rolls and mats, which can be used to insulate roofs, floors, building facades, ceilings, walls and floors, and ventilation pipes. The basis of Isover are glass fibers with a length of 100 to 150 microns and a thickness of 4 to 5 microns. Thanks to these parameters, the insulation has a high elasticity, as well as resistance to stress.

Characteristics of Izover heaters

This material is made of the highest quality fiberglass according to TEL technology, which is patented. All this makes Isover one of the best heat insulators, differing from analogues for the better. We list its useful qualities.

Thermal conductivity

The thermal conductivity of this heater has a tiny value of 0.041 watts per meter per Kelvin. Moreover, this value does not change with time in the direction of increasing (as often happens with other heat insulators). Thus, Isovere's glass fibers, which hold air well, perfectly conserve heat.

Soundproofing

As regards the ability to protect from external noise, here too fiberglass materials are at a height. This is again due to the fact that there is an air gap between the glass fibers, which successfully retains extraneous sounds. Therefore, silence in the room, warmed Izover, you will be provided. For these purposes, released special varieties of material.

Flammability

All thermal insulation materials having a density of up to 30 kilograms per cubic meter and called Isover are considered non-combustible. So they are determined by the corresponding GOST 30244-94, which assigns them the abbreviation NG. Therefore, it is quite possible to use such insulation in any houses - Isover's characteristics of this type allow it. Its use is absolutely safe for thermal insulation of both a single-story cottage and a high-rise building.

Hard and semi-rigid materials, as well as those coated with Tyvek film, aluminum foil or fiberglass, are considered mildly flammable. According to GOST, they are designated SG. Restrictions for the use of such heaters are available, but they are few. So they can be applied almost everywhere. The main thing is to strictly comply with the fire safety regulations of buildings and structures set out in SNiP 21-01-97.

Vapor permeability

Now let's talk about resistance to moisture. After all, this parameter is the "weak link" of many modern heat insulators. They perform their function well only when the indoor air is dry. If it contains moisture, even the ability to retain heat in fiberglass may deteriorate. But glass fibers are good because they quickly give back all the moisture that they have absorbed. And for this you need not to forget to leave a gap between the wall and the insulation, not less than 2 centimeters for ventilation. If this is not done, the thermal insulation qualities of this material will decrease as moisture is absorbed. Unfortunately, this is a lack of all such materials. Isover's vapor permeability is within 0.50 - 0.55 mg / mchPa. At moistening of a heater for 1% there is a sharp deterioration in thermal insulation up to 10%.

Lifetime

The most important parameter is the life time of the insulation. Even if it keeps warm well, but it can last for a year, it is unlikely someone will like it. To warm the house is a painstaking occupation, and every year it’s not a pleasant thing to do. But, fortunately, these claims do not apply to Izover. Having laid walls, floors or ceilings with this material, you can forget about insulation for many years. There are examples of the use of this heater for more than 50 years without loss of thermal insulation qualities.

And still Isover has water repellents in its composition, which have water-repellent properties. In addition, bugs and other insects do not settle in this insulation - they don’t like this habitat. Fiberglass insulation is not available for mold.

Environmental friendliness and safety

Not only technical characteristics Isover can shine. Fiberglass materials of this type are absolutely harmless to human health and life.During their operation no harmful substances are released. For half a century, Finnish scientists have verified this fact. No danger was found - experts of the Institute of Cancer Problems repeatedly passed such a verdict.

Heater weight

If I compare Isover with other heat insulators by weight, but it will be much lighter than the others. Therefore, in those buildings, the walls of which are made of not very strong materials or an excessive load is unacceptable, the use of Izover will prove to be an excellent way out.

Release form

For the convenience of consumers, this heater is produced in various forms. These are rolls, plates of various rigidity, mats. The thickness of a single-layer Isover varies from 5 to 10 centimeters, and for a two-layer one, the thickness of each layer is 5 centimeters. Plates are usually made of no more than a meter per meter, but sometimes there are exceptions.

Isover's packaging in the form of pressed plates.

The area of ​​one roll is from 16 to 20 square meters. The standard roll width is 1.2 meters, and its length is from 7 to 14 meters.

Isover in pressed rolls, when unpacking, unpacks itself.

Other characteristics

• Density is about 13 kg / m3.
• The density of the junction to the base is not very good and may decrease depending on the object being insulated.
• Breathability is 120 * 10-6m ³ / m * s * Pa.

In general, many characteristics will depend on the type of material and its purpose; for more details, all characteristics can be viewed on the Isover official website.

Where Izover and its varieties are used

Well, as a heater, Izover has quite good characteristics. Therefore, it can be used widely - and during the construction of the house, and with exterior and interior decoration. For example, with an isover you can perfectly warm the floor, under which it blows from the basement. They can enclose walls for insulation, attic or attic, as well as protect the walls from the cold wind. By the way, such a warming will be relatively inexpensive.

This material has several varieties. Each of them is designed to perform specific work. Next we list them.

Isover KL34

Isover KL34 is produced in the form of slabs 5 or 10 centimeters thick. They are mounted tightly on the frame; in addition, you do not need to use fasteners. Such plates can isolate the ventilated facade and masonry, consisting of several layers. The planes are suitable for warming any: vertical and horizontal, and those that are tilted.

Isover KL37

Isover KL37 is supplied in tightly compressed packages. It also does not require additional fasteners for installation. This material is used to insulate ceilings between floors, walls, roof slopes. At the same time, a tight fit of the material to the surface is necessary.

Isover KT37

Isover KT37 is produced in compressed rolls. Fasteners do not require, but, like the previous material, should fit well to the heat-insulated plane. It is used for thermal insulation of roofs, attics, floors between floors, walls and partitions inside rooms.

Isover KT40

Isover KT40 is a two-layer material (each layer has a thickness of 5 centimeters), which is produced in the form of tight rolls. It is used without additional fasteners for insulation of surfaces located horizontally - floors and ceilings. If the cavity is filled with insulator of insufficient depth, then the isover can be divided into two layers.

Isover STYROFOAM 300A

But material such as Isover STYROFOAM 300A requires the use of fasteners. It comes in the form of hard, rough slabs whose surface adheres well to concrete. The structure of this insulation is extruded polystyrene foam, due to which isolated cells are formed. Due to this increase the temperature resistance and moisture resistance. This heat insulator is suitable for work on both horizontal and vertical surfaces. They are warmed exterior and interior walls, floor and flat roof. From above it is possible to put plaster.

Isover VENTITERM

Isover VENTITERM is a universal insulation material. After all, the technical characteristics of Isover of this type are such that it is possible to work with it both with fasteners and without it. Release it in the form of hard plates, treated with water-repellent agent. The basis of this material is mineral wool, consisting of basalt fibers. They are insulated (on the one hand) by ventilated facades, as well as pipes for ventilation and plumbing. It is also used to protect against the precision of cold instruments.

Isover sloping roof

Isover sloping roof - insulation used for roof insulation.Available in the form of plates with a width of 61 cm and a thickness of 10 or 5 centimeters. It practically does not absorb moisture, and also absorbs sounds well. High vapor permeability and incombustibility are two more useful properties of this material. It keeps warm well, especially if you use its two layers, the top of which covers the bottom joints. Important: during installation, the step of the rafter system must be done in such a way that the insulation plates do not fall through.

Isover ventilation façade

Isover ventilation façade is no different from ordinary Izover. It is produced in a two-layer form, so it keeps heat well. When installing, do not let the insulation lag from the surface.

Isover soundproofing

Isover soundproofing comes in the form of mats and slabs. He is able to better protect other rooms from external insulation. It is used to isolate suspended ceilings and internal partitions.

What you shouldn’t do when working with Izover and its disadvantages

According to safety precautions, when using fiberglass materials, it is necessary to wear safety glasses, gloves and a gauze bandage. We should not forget about clothes with long sleeves, pants and socks. But in the summer in a stuffy attic, oh, how you do not feel like it! So many are hoping at random, exposing the torso and deftly pasting the isover plates. At first, it seems to be nothing, but then you have to regret. The whole body begins to desperately burn and scratch, and even a shower does not help.

When working with this material, try to get up so that bright sunlight hits the isover. And you will see poles of fine glass dust in the air. It seems that this spectacle will be able to discourage work without protective equipment. But do not be afraid - the laid heater will not be dangerous. As a proof, we will give an example: sometimes even the wasps build nests in the isover, and gnaw the holes in the mice. But this can only be where it is environmentally safe.

And in order to know for sure that glass dust will not get into the rooms, lay a Yutavik-type film between Izover and the wall paneling. And then, even if the wall panel gradually cracks, no glass particles will threaten you. However, if you compare Izover with the domestic capping glass wool, penetrating through any protection, then the comparison will clearly be in favor of the first. And mice, by the way, disgust glass wool, unlike Izovera. So there is reason to think.
