Abstract

It is established that the increase of 1m2 mass and density as well as the decrease of fiber diameter allows to obtain the wide range of insulating materials without changing composition at the decrease of heat loss coefficient in 2.5 – 4.0 times, increase of sound absorption and strength coefficient in 1.5 – 5.0 and 1.3 – 3.5 times accordingly.
