Rock wool board with fiber glass fabric

Product properties and applications The main materials of the rock wool board are natural rock and blast furnace slag. It is manufactured with proper binders by high temperature melting, solidifying and cutting. It has characters of light weight, good elasticity and high intensity. It also has functions of heat retention, thermal insulation, sound absorption and fireproofing. It can be widely used for the heat retention and thermal insulation of building walls, ceilings, industrial furnace, oven, heat treatment equipment, tanks, power plant, flue, petrochemical equipment as well as some other tubes. It is easy to construct and install. The energy-saving effect is very good. It has an excellent price-performance ratio.
