Insulation "Rockwool": specifications for moisture, size, density. Reviews

The modern market of building materials is presented by heaters of the most different types and marks. 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.

Rockwool - 80 years on the market

The first factory for the production of building materials "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.

Insulation "Rockwool": technical characteristics. Density

The value of this parameter in most cases affects the degree of thermal conductivity of cotton wool. That is, the denser the material, the worse it keeps the heat. However, the features of the technological process for the manufacture of insulation "Rockwool" are such that this rule does not apply to it practically. So, for example, materials with a density of 35 and 200 kg / m ³ in terms of the degree of thermal conductivity differ only by 0.002 W / m.

Insulation "Rockwool": technical characteristics. Degree of thermal conductivity, vapor permeability and moisture absorption

The quality and efficiency of protecting the building from the properties of the material 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 factor for this kind of construction materials is the degree of vapor permeability. So the ability of plates and mats to pass through their thickness air, saturated with water vapor. At "Rockwool" heaters, this figure 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, we do not have methods in our country that can accurately determine the longevity of the insulation. 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.

Soundproof properties

The "Rockwool" insulator, the technical characteristics of which 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 / m ³ ). 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.

Environmental Safety

Everyone knows that the production of mineral wool used compounds containing phenol-formaldehyde resins. Therefore, for insulation of residential buildings it is recommended to use only high-quality materials of this kind. The latter can safely be attributed and insulation "Rockwool". 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 Expert opinions on compliance with sanitary norms. 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.

Popular varieties of cotton and sizes

The insulation "Rockwool", the technical characteristics of which allow us to judge it as one of the best for today, is produced in:

• Matah. This soft wool, supplied in rolls, is usually used for insulation of structures that do not experience external loads. Where can I apply this particular insulation "Rockwool"? Technical characteristics for the roof or insulation of its walls can be considered simply ideal.
• Plates. This kind of insulation can be either hard, or soft or semi-soft. In the first case, it is usually used to insulate floors and floors.
• Cylinders. This type of material is used for the insulation of communication pipes.

As for the size of insulators, they can be very different. Modification of Light Batts Scandic is 1200 * 600 cm plates 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, this version is very convenient to use. Heater "Rockwood Scandic", the technical characteristics of which allow it to be used on objects of various purposes, including the construction of private houses, is currently the most popular type of this brand.

Modification "Light Butts" is the same size 1000 * 600. The thickness of the material can vary from 5 to 20 cm. Rockwool Flexi-Batts semi-rigid plates 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.

Heat Insulators for Heated Surfaces

The company "Rockwall" has a line of materials intended, including for the insulation of fireplaces, chimneys and stoves. This, for example, Rockwool "Tech Butts", Rockwool Wired Mat or Rockwool "Fiere Butts." These materials can be used to insulate structures whose surfaces are heated to a temperature of not more than 750 degrees.

Reviews of the material "Rockwool"

Thus, we with you in general have found out, that represents a heater "Rockwool" (technical characteristics). Reviews about this material from consumers are mostly positive. Users of the Internet on forums especially note such qualities as simplicity in installation and excellent heat-saving properties. Apply this insulation is advised 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 houses when working with this material, however, sometimes itches their hands and body. 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. If the plates are stored for a long time in a garage or a household unit, or during transportation, it sometimes breaks.

How to choose the right thickness

The "Rockwool" insulation, the technical characteristics of which allow it to be used for the insulation of any buildings, must 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 sufficient to install two layers of "Rockwool" slabs of 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 accurate calculation.

Rules for the installation of insulation Rockwool

Mount materials of this brand in the same way as mineral wool of any other manufacturer. That is, by 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 finishing, an air gap should be arranged. If the plates stand between the studs sufficiently tightly, they are not required additionally, even if two layers are used.
