Basically, this material has many pros and cons of mineral wool - because their properties are very close.He produced in the form of plates, both rigid and semi-rigid.And yet it is sold in rolls and mats, which can insulate the roof, floors, facades, ceilings, walls and floors, ventilation

pipes.The basis Izover are glass fibers with a length of 100 to 150 microns and a thickness of 4 to 5 microns.With these parameters heater has high elasticity and resistance to corrosion.

Features Isover insulation

This material is made of glass of the highest quality technology TEL, which is patented.All this makes Isover one of the best thermal insulators, differs from its analogues for the better.We list their beneficial qualities.

Thermal conductivity Thermal conductivity of the insulation has a tiny value - 0,041 watts per meter per Kelvin.And this figure does not change over time in the direction of increasing (as often happens with other heat insulators).Thus, glass fibers Isover, good air retention great save heat.


As for the ability to protect against external noise, here at the height of fiberglass materials.This is due again to the fact that between the glass fibers is a layer of air that successfully retards extraneous sounds.Therefore, the silence in the room, insulation Isover, you will be assured.For this purpose, special varieties of material released.


All insulating materials having a density of 30 kilograms per cubic meter and is known as Isover, are considered to be non-combustible.So they determine the relevant GOST 30244-94, which assigns them the abbreviation NG.Therefore, such a heater it is possible to use any houses - Isover characteristics of this type allow it.Its use is safe when insulation as a one-storey cottage, and high-rise building.

hard materials and semi-rigid type, as well as those of the film is coated Tyvek, aluminum foil or glass, are considered to be poorly flammable.According to GOST they are designated SG.Restrictions on the use of such heaters are available, but they are few.So they can be used almost everywhere.The main thing - to strictly implement the provisions of fire safety of buildings and structures outlined in the SNIP 21-01-97.Water vapor permeability

Now let's talk about the resistance to moisture.After all, this option is the "weak link" of many modern thermal insulators.They perform their function well only when the indoor air is dry.If it contains moisture, even from fiberglass ability to store heat may deteriorate.However, glass fibers are good that quickly give back all the moisture, which is absorbed.And for this we must not forget the insulation between the wall and leave a gap not less than 2 cm for ventilation.If this is not done then the insulating qualities of the material will decrease as napityvaniya moisture.Unfortunately, this lack of all these materials.Isover Water vapor permeability in the range of 0.50 - 0.55 mg / mchPa.When moisture insulation at 1%, a sharp deterioration in the thermal insulation of up to 10%.


most important parameter is the life of the heater.Even if he keeps the heat well, but is capable to serve on the strength of year, it is unlikely someone will like.Insulate the house - it works laborious, and to do it every year - it is not pleasant.But, fortunately, to Isover these claims do not apply.Route the walls, floor or ceiling of this material, you can forget about insulation for many years.There are examples of the use of the heater for more than 50 years without losing heat-insulating properties.

And Isover in its composition has a water-repellent agents, which have a water-repellent properties.In addition, this does not settle the insulation beetles and other insects - not like it is a habitat.Hidden fiberglass insulation and mold.

Sustainability and the harmlessness

not only the technical characteristics of Isover can flash.Glass materials related to this type are completely harmless to human health and life.During their operation no harmful substances are released.For half a century Finnish scientists verified this fact.The dangers were found - a verdict of experts from the institute have repeatedly endured the problems of cancer.


insulation Isover Compared with other heat insulators by weight, but it will be much easier than the others.Therefore, in those buildings, whose walls are made of very durable materials are not unacceptable or excessive burden it would be an excellent use of Isover way out.

release form

For the convenience of consumers the heater is available in different form.It rolls, plates of varying hardness and matting.Izover monolayer thickness ranges from 5 to 10 centimeters, while the double layer - the thickness of each layer is 5 cm.Plates are usually made of no more than one meter on, but sometimes there are exceptions.

Isover in slabs
Packaging Isover in the form of compressed slabs.

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

Isover rolls
Isover in compacted rolls, when removing the packaging envelope yourself straightened.

Other features

  • density is about 13 kg / m3.
  • density contiguity to the ground is not very good and may be reduced depending on the insulated object.
  • air permeability is 120 * 10-6m3 / m × a × Pa.

In general, many features will depend on the type of material and its purpose, details all the features available on the official website of the company Isover.

Where used Isover and its variants

Well, as Isover insulation characteristics is good.Therefore, it can be widely used - and during the construction of the house, and outside and inside finishing.For example, Isover can be perfectly insulate the floor, under which blows from the basement.They can impose the walls for insulation, attic or attic, and also to protect the walls from the cold wind.Incidentally, the cost is relatively inexpensive insulation.

This material has several varieties.Each of them is designed to perform a specific job.Then list them.

Isover KL34

Isover KL34 is available in the form of panels of 5 or 10 centimeters thick.On the frame are mounted firmly, while further fasteners use is not necessary.Therefore plates can be insulated and ventilated facade of masonry, consisting of several layers.The planes under any suitable insulation: both vertical and horizontal, and those who are inclined.

Isover KL37

Isover KL37 comes in tightly compacted packages.It also does not require additional fasteners during installation.This material insulated overlap between the floors, walls, roof slope roof.It should be a tight fit to the surface of the material.

Isover KT37

Isover KT37 is available in the form of compressed bales.Fastening elements does not require, but, as the previous material must adhere well to the insulated surface.It is used for thermal insulation of roofs, attics, ceilings between the floors, walls and partitions inside buildings.

Isover KT40

Isover KT40 - ply material (each layer has a thickness of 5 cm), which is produced in the form of tight coils.It is used without additional fasteners for insulation surfaces arranged horizontally - floors and ceilings.If the cavity is insufficient to fill the depth of the insulation, it is possible Izover divided into two layers.


But a material such as Isover STYROFOAM 300A, requires the mandatory use of fasteners.It comes in the form of solid plates rough surface which adheres well to concrete.The structure of this part of extruded polystyrene insulation, thanks to which the image of isolated cells.This increases the heat resistance and moisture resistance.This insulator is suitable for both horizontal and vertical surfaces.They insulated exterior and interior walls, the floor and the flat roof.From above, you can apply the plaster.

Isover VENTITERM - versatile insulation.After all, the technical characteristics of this type of Isover is such that it can work as a binding material, and without it.Release it in the form of rigid plates, treated hydrophobizator.The basis of this material - rock wool, consisting of basalt fibers.They insulate (with one hand), ventilated facades, as well as pipes for ventilation and plumbing.Once it is used for protection from the cold precision instruments.

Isover pitched roof

Isover pitched roof - insulation is used for thermal insulation of the roof.Available in the form of plates 61 cm width and a thickness of 5 or 10 centimeters.It almost does not absorb moisture and absorbs sounds.High vapor permeability and flammability - two useful properties of this material.It keeps excellent heat, especially if you use two of its layers, the upper joints of the lower closes.Important: When installing the system step rafters should be done so that the insulation boards are not failed.

Isover Ventfasad

Isover Ventfasad is no different from ordinary Isover.It comes in the form of a two-layer, so well kept warm.When installing the heater, do not allow the backlog from the surface.

Isover zvukozaschita

Isover zvukozaschita issued in the form of mats and plates.It is capable of better than other insulation to protect the room from external sounds.It is used for insulation of ceilings and internal partitions.

What not to do when working with Isover and disadvantages

According to safety when using glass fiber materials it is necessary to wear protective goggles, gloves and bandage gauze.Do not forget about the dress with long sleeves, pants and socks.That's only in the summer on a stuffy attic to pull it all oh how you do not want!So many are hoping at random, revealing a torso and deftly pasting boards Isover.First, like anything, but then have to regret.All of the body starts to itch and burn fiercely, and even shower helps.

working with this material, try to get up, so that at Isover got the bright sunlight.And you will see in the air pillars fine glass dust.I think that this show could discourage work without protective equipment.But fear not - the laid insulation danger is not.As proof we give an example: Isover sometimes even wasps build nests and burrows mouse burrow.But this can only be where environmentally safe.

And to know exactly what glass dust does not get into the room, sandwiched between Isover and lining for wall film type yutavika.And then, even if the lining is gradually rassohnetsya, no glass particles will not threaten you.However, when compared with the national prickly Isover glass wool penetrating through any defense, the comparison will clearly be in favor of the former.A mouse, by the way, glass disdain, unlike Isover.So there is a reason to think.
