A lot has been written about the need to insulate buildings and structures. The fact is that in the last century the technology of housing construction did not provide him with complete comfort and coziness. Given the specifics of Russia's climate, in the winter, apartments were often cool, and in the summer - hot. One of the reasons was the lack of cheap and effective insulating materials. Since the majority of citizens of our country live in houses still "Soviet" construction, the issue of insulation of dwellings is not in the last place. Today we will review the characteristics of a popular heat insulation material, such as URSA.
That gives insulation
- maintenance of a comfortable temperature in premises irrespective of weather in the street. Since insulation materials have a low thermal conductivity, they are excellent insulators. It is this property that avoids fluctuations in the temperature inside the building;
- increase the service life of all structural elements of the structure, as well as all items in it;
- significant reduction in energy consumption. Consequently, in the winter savings on heating, in the summer - on air conditioners.
URSA is one of the inexpensive, and therefore quite affordable insulating materials. Its basis is staple glass fiber, and it belongs to the category of "mineral wool."The product goes on sale in the form of plates or mats. There are several grades, depending on the density.
Insulation grades URSA
M - 11 is most often used in individual construction. Due to the plasticity it is easy to "fit" on hard-to-reach areas of surfaces. It is used for insulation of floors, roofing, interfloor overlappings, engineering communications. The best way to install is horizontal.
The insulator M-11-F has an additional layer of aluminum foil, which acts as a vapor barrier. When using this brand is not required to install a separate vapor barrier layer.
M - 15( P - 15) differs from other brands only in size. It is advisable to apply for the insulation of roof slopes, for internal insulation of walls.
P - 20 has a high density. It is recommended for arrangement of an external heat-insulating layer. Excellent for finishing interior partitions.
P - 30( - C) is considered a universal material. More suitable for industrial use. The letter "C" means that the surface has been glued with fiberglass.
Properties of the insulation of the Ursa
- good heat and sound insulation;
- can be used at temperatures from -69 to + 180 degrees;
- elasticity.
- The diameter of one fiber does not exceed 5 microns. This greatly simplifies the installation process. The elasticity of the material ensures its full adherence to the surface being removed;
- material is warmer than, for example, penoplex, styrofoam;
- group of flammability from SG to NG( depending on the brand).
Some characteristics of URSA
- density from 9 to 32 kg / m3
- thermal conductivity( at + 25 degrees) from 0.39 to 0.44 W / mK
- strain at 2000 Pa pressure from 40 to 90%
It should be clarified that this dataare given as generalizing for all brands of the product. At each particular they are different, but are in the specified range.
