Vspuchenny vermiculite is applied at fire protection and to increase of level of thermal insulation of construction objects, the bearing designs (air ducts, mines, interfloor, garret and basement overlappings, interroom and interroom partitions). Dry construction mixes and construction solutions which filler is vermiculite are effectively applied.
Fireproof efficiency of vermikulitovy solutions is 4 times higher, than sandy. Vermikulitovy solutions possess frost resistance – from 25 to 50 cycles. The coefficient of heat conductivity is 4-6 times less, than at usual cement and sand. The layer in 2 cm is equivalent on a heat transfer to a bricklaying 1 thick a brick. The layer in 20 cm is equivalent to a brick wall 1,5 m thick or concrete in 2 m.
Filling from vspuchenny vermiculite
The world practice showed that vermiculite is successfully applied as a fireproof bulk heater. The vermiculite layer on garret overlappings 5 cm thick reduces losses of heat by 75%, thickness 7,5sm – for 85% and 10 cm thick – for 92%. Vermikulitovy fillings in wall designs are applied for:
- protection of rooms against overheating or cooling;
- heat insulations of refrigerating and high-temperature processing equipment;
- sound insulation and sound absorption.
