Product Description

Description:

Glass Wool

Because of a large number of tiny air interspaces, it has the functions of heat insulation, sound absorption, safe guarding and etc, so it is the best materials of heat insulation and sound absorption in construction.

Applications:

It is widely used for heat insulation and sound absorption in industrial workshops, warehouses, public facilities, exhibition centers, shopping malls, and a variety of indoor playgrounds, sports stadiums and etc.
