Rock Wool Board

Rock wool board is manufactured in a unique process using high quality basalt ore as the main raw material. rock wool board has the features like high strength, high temperature resistant, corrosion resistant and good thermal conductivity. Rock Wool is widely used in external wall insulation, roof insulation, composite sandwich panels, fire door core panels, and various industrial and marine equipment, pipeline insulation. High rigidity and light weight, Excellent fire resistance, thermal insulation, sound absorption, Easy to be machined, cut and shaped.
Application
Thermal insulation of industrial and civil building

Sound absorption of building exterior wall

Fire prevention of ship equipment

Interlayer of steel insulation board

Back Lining in industrial furnace
