In construction vspuchenny vermiculite finds application thanks to the unique properties: ease, low heat conductivity, fire resistance, high sound absorption and harmlessness. At construction of industrial facilities by means of filling izvermikulitamozhno to solve non-standard problems of noise-absorbing, protection against ultrahigh or ultralow temperatures. Vspuchenny vermikulitpozvolyat izolirovatpoverkhnost from minus 260 °C to plus 1100 °C. When using vspuchenny vermiculite a kaknapolnitel in easy betony of plaster it is possible to achieve the solution of several tasks: reduction of weight of material, thermal insulation, sound insulation and fire protection
Vermiculite as a part of plasters solves one more major problem of construction - fire protection. We recommend to builders to apply vermikulitovy plasters at construction and finishing of public buildings, in particular, of cafe, restaurants, the shopping, entertainment and sports centers. Advantages of vermiculite:
1. High sound absorption;
2. Preservation of small weight at large volumes;
3. Fire resistance (1320C);
4. Low heat conductivity (0,04 - 0,062 W/m. J);
5. Not susceptibility to rotting;
6. Prevention of development of a fungus and mold;
7. Not the favorable environment for rodents.
Full thermal insulation and sound insulation!
Vermiculite is used as zasypny thermal insulation for warming of floors, roofs. At this type of use sound-absorbing properties of vermiculite are of great importance. With its help it is possible to achieve almost complete silence in any of rooms.
Health and safety!
Being nonflammable, vspuchenny vermiculite is capable to sustain temperature from - 260 to + 1250 degrees. It remains absolutely safe for health even at the fire because when heating does not emit gas. At the same time material belongs to "breathing" - it not just maintains comfortable temperature indoors, but also passes air through itself(himself), creating effect of conditioning.
Economy!
Using vermiculite vspuchenny it is possible to save on a brick, concrete, etc. This mineral in many parameters wins in comparison with other materials which are used in construction that it is possible to estimate even on one example:
only the 20-centimeter layer of friable vermiculite on the heat-insulating qualities is equal to a brick wall 230 cm thick or a concrete wall 450 cm thick. Having warmed walls warm plaster with vermiculite, it is possible to make them thinner, using heat-insulating properties of vermiculite.
