Every owner of his own apartment or house,who wants to live in comfort and peace, tries to protect himself as much as possible from extraneous noise and winter cold. For heating, fire was first used for fireplaces and boilers, after which electric heaters joined them. All this is not so effective if the house is not well insulated and has places through which precious heat is evaporating. However, if you use mineral wool insulation, you will be able to protect your house from frost in winter, and also to save yourself from the heat in the summer.
Mineral wool insulation has severalvarieties, each of which has its own merits and demerits. In order to make the right choice in the direction of this or that isolation, it is necessary to become more familiar with the qualitative characteristics of the materials.
Having read the information provided inGOST 52953-2008, you will learn that to mineral wool are three materials, namely stone wool, fiberglass and slag wool. Any of them can be purchased by visiting the building materials store. Each of the listed varieties has a certain thickness and length of the fiber, and also differs in qualitative characteristics. For example, they have different resistance to loads, moisture resistance, and also thermal conductivity.
Steklovata has been used for a very long time, andtoday it can be purchased at the lowest possible price. But working with it, unlike slag and stone wool, is very difficult, because it is prickly. The master during the installation will have to use personal protective measures.
If you need mineral wool insulation, thenYou can pay attention to glass wool, which consists of fibers with a thickness ranging from 5 to 15 microns, while their length can vary from 15 to 50 millimeters. Glass wool has strength and elasticity, and its coefficient of thermal conductivity varies from 0.03 to 0.052 watts per meter per Kelvin. It is possible to heat the material without damaging the structure up to 500 degrees, and the optimum temperature, when the thermal insulation maintains its characteristics, is 450 degrees. As for the minimum temperature, it reaches -60 degrees.
Mineral wool insulation is on salealso slag wool, which is made from blast furnace slags. The thickness of the fibers of the material is equal to the limit of 4 to 12 microns, but their length is equivalent to 16 millimeters. Due to the fact that slags have residual acidity, in a damp room they are able to act on metal objects. Slag wool absorbs moisture well, so it should not be used for thermal insulation of external walls of buildings.
For the above reasons, this materialcan not be used for insulation of water pipes, which are made of plastic or metal. The coefficient of thermal conductivity is higher compared with the above described type and makes a limit from 0.46 to 0.48. Heat insulation can be up to 300 degrees, while it does not lose its quality characteristics. If this value is exceeded, the fibers will begin to sinter, and the material will lose its thermal insulation characteristics. Hygroscopicity of this heater is very high.
Минераловатный утеплитель представлен в магазинах also in the form of stone wool, the fibers of which are approximately the same in size as in the slag wool described above. However, the advantage is that the elements do not prick, so it’s safer to work with stone wool. The coefficient of thermal conductivity can be equal to 0.077, while the maximum value is 0.12. The material can heat up to 600 degrees without losing its properties.
Basalt mineral wool insulation of thismarks intended for use not only in industrial, but also in civil engineering. Such plates are used in the role of sound and heat insulation in external wall insulation systems. After installation of the material, a protective-decorative layer of thin-layer plaster is laid. Thermal insulation does not burn, it is represented by hydrophobic plates, which are made on the basis of basalt rock rocks. The production process uses a low-phenolic binder.
Quite often, experts are interested in the density of mineral wool insulation. In the case described, this parameter varies from 131 to 135 kilograms per cubic meter.
Perhaps for installation work will haveto equip the crate, for this you need to ask about the size of the plates. For example, the length can be equal to 1000 and 1200 millimeters, as for the width, it is equivalent to 500 or 600 millimeters. Thickness in increments of 10 mm varies from 40 to 150 mm. The vapor permeability of this heater is 0.3 Mg / (m · h · Pa), while the humidity by mass does not exceed 0.5%. Water absorption is not more than 1% by volume, and the content of organic substances can be 4.5% at most.
Rockwool mineral wool todayis very popular among consumers. A kind of heat insulation "Light Butts" is a hydrophobised heat-insulating plates, in the manufacturing process of which stone wool based on basalt rocks is used. The main feature of this heater is a unique technology, which provides for the formation of one edge of the plate so that it has the ability to unclench and shrink. Thanks to the ability to spring installation easier when mounting structures on a metal or wood frame.
The described mineral wool slabs possessmany benefits. Among them it is necessary to highlight the absence of cold bridges, durability, environmental friendliness, fire safety and the most dense junction with each other.
These plates are used asnon-loading layer in the construction of attic rooms, light coatings, interfloor floors, as well as partitions and walls of low-rise buildings. Included here are sloped and vertical walls in attics, as well as a layer in hinged facade systems. In the latter case, there is a need to form an air gap when a two-layer insulation is established. These mineral wool plates should not be subjected to significant loads. During installation, the master will be able to form a surface without the formation of gaps. As a result, there will be no drafts inside the rooms, and comfortable temperature will be maintained in the rooms.
In order to most effectively providethe house has thermal insulation qualities, you need to ask what is the thickness of the mineral wool insulation. In the Light Butts version, this parameter varies from 50 to 100 millimeters. While the length and width remain unchanged and equal to 1000 and 600 millimeters, respectively.
