The modern market of building materialsis presented by heaters of the most different types and brands. One of the most popular varieties are basalt slabs and mats. Produce similar products, many manufacturers - both foreign and domestic. Very good reputation has, for example, a basalt insulation "Rockwool", produced by a group of companies with the same name.
The first plant for the production of constructionmaterials "Rockwool" first released its products in the distant 1937. By the end of the 50s, the company owned six plants located in different countries of Europe. Today it is a large group of companies, which owns 27 factories around the world. Their specialization is the production of materials intended for insulation, sound insulation and fire protection of structural elements of residential and industrial buildings. The central office of the company is located in Hedehusen in Denmark.
The value of this parameter in most casesaffects the degree of thermal conductivity of cotton wool. That is, the denser the material, the worse it keeps the heat. However, the peculiarities of the technological process for manufacturing the "Rockwool" insulation are such that this rule does not apply to it practically. So, for example, materials with a density of 35 and 200 kg / m3 by the degree of thermal conductivity differ only by 0.002 W / m.
Quality and efficiency of building protection from propertiesmaterial depend directly. The degree of thermal conductivity of insulators of the "Rockwool" brand can fluctuate within (0.036-0.038 W / mK). This means that a five-centimeter layer of material will retain heat as well as 96 cm of brickwork. In the summer in the house, the enclosing structures of which are lined with this insulator, it will be cool, and in winter - heat.
Another important for this type of constructionThe index is the degree of vapor permeability. This is the name of the ability of plates and mats to pass through their thickness air saturated with water vapor. At insulation «Rockwool» this indicator can reach more than 0.25 mg / (m * h * Pa). If we take into account the fact that the hydrophobicity of this material is very high (and, consequently, it absorbs moisture poorly), the structures protected by it are not damped and do not decay. The water absorption coefficient of the most popular version of "Light Batts Scandic" is no more than 330. As you can see, in fact, a good choice may be a "Rockwool" heater. Specifications for moisture allow it to be used even in damp areas.
Unfortunately, techniques that allow for accuratedetermine the longevity of the insulation, we do not have in the country. However, Rockwool developed its own technologies for determining the quality of materials produced and their durability. In addition, observations of the behavior of heaters have been carried out by its specialists for many years, beginning with the release of the first lots from the conveyor. All this allows us to conclude that the "Rockwool" heater can be used for more than 50 years if the rules of its installation and operation are observed.
Rockwool Heater, technical specificationswhich were considered above, can be used, including as a soundproofing device. In this case, it is worth buying a material with a high density (not less than 45 kg / m3).The company and slabs designed specifically for this purpose are produced by Rockwool Acoustics Butts. To install their manufacturer recommends in a frame on vibroprokladkah or in "floating" floors. In the latter case, you can also use the modification Rockwool Flor Butts. Its advantage is that the screed can be laid directly on it.
Everyone knows that in the production of mineralWATER uses formulations containing phenol-formaldehyde resins. Therefore, for the insulation of residential buildings it is recommended to use only high-quality materials of this type. The latter can safely be referred to as a "Rockwool" heater. In its production, resin of the new generation is used to bind basalt fibers. The binder content, in which they are included, does not exceed 3.3% in plates and mats. The resin is in a solid state, and therefore, poses no danger to the environment and human health.
All products of "Rockwool" have Expertconclusions on compliance with sanitary standards. In addition, all the cotton wool of this brand is certified EcoMaterial Green. This indicates that this product can be used in absolutely any premises, including health and children's.
The insulation "Rockwool", the technical characteristics of which allow us to judge it as one of the best for today, is produced in:
As for the size of insulators, they canbe very different. Modification of Light Batts Scandic is a plate 1200 * 600 cm with a thickness of 5 cm or 800 * 600 with a thickness of 5 and 10 cm. Since the step between the racks of the carcass of houses or roof rafters is usually 60 cm, in use this species is very convenient. Heater "Rockwood Scandic", the technical characteristics of which allow it to be used on objects of most different purposes, including in the construction of private houses, is currently the most popular type of this brand.
Modification "Light Butts" is the same size1000 * 600. The thickness of the material can vary from 5 to 20 cm. The semi-rigid Rockwool Flexi-Batts have a length of 560-1020 cm, a width of 900-1000 cm and a thickness of 5-20 cm. There are other varieties of this material (Rollbatts-Dk, Venti- Batts-Dk, etc.). Such insulation "Rockwool", technical characteristics (dimensions and density) can have different.
The company "Rockwool" has a line of materials,intended, including for the insulation of fireplaces, chimneys and stoves. This, for example, Rockwool "Those Butts," Rockwool Wired Mat or Rockwool "Fiery Butts." These materials can be used to insulate structures whose surfaces are heated to a temperature of not more than 750 degrees.
Thus, we have in general terms found out,what is a "Rockwool" heater (technical characteristics). Reviews about this material from consumers are mostly positive. Internet users at forums especially note such qualities as simplicity in installation and excellent heat-saving properties. Apply this insulation advise for the insulation of walls not only of residential buildings, but also baths, terraces, etc. When installing Rockwool does not crumble, do not fall apart and does not fly around the house.
Some owners of country houseswork with this material, however, sometimes the hands and the body are scratched. But this, in principle, is a general drawback of all mineral wool. The manufacturer "Rockwool" advises to work with their plates only in gloves and in tight close clothing. Some consumers do not like the cellophane packaging of this material. With prolonged storage of plates in the garage or the household unit, or during transportation, it sometimes breaks.
Rockwool Heater, technical specificationswhich can be used to isolate any buildings, should be selected taking into account some important points. The most important parameter, in addition to the density and rigidity, is the thickness of the material. Choose it follows, guided by the norms of SNiP 23-20-2003. The calculation is carried out according to special tables taking into account the climatic conditions and the degree of thermal conductivity of the material. Usually for insulation of a residential building it is enough to install two layers of "Rockwool" slabs at 5 cm or one layer of 10 cm. There is also a special calculator on the official website of the company, according to which it is possible to make an exact calculation.
Mount the materials of this brand in the same way asmineral wool of any other manufacturer. That is, when inserting plates between the frame racks or rafters, you should try not to crush them. Otherwise, they will lose some of their thermal insulation properties. When installing from the inside or outside, it is not necessary to lay the wall structure under the plates with any steam or waterproofing material. Over the heater they are installed necessarily. When installed from the inside, it is vapor-insulating, outside - hydro-inductive. Between these layers and the finishing finish, a ventilation gap must be arranged. If the plates stand between the studs sufficiently tightly, they are not required additionally, even if two layers are used.
