Calcium silicate board is an asbestos-free thermal insulation product that can withstand continuous operating temperatures up to 1000 ºC. It is lightweight, has low thermal conductivity and high strength, and is easy to install.
Calcium silicate boards are commonly used as furnace backup insulation in the steel, petrochemical, ceramic, cement & glass industry or fire protection in building construction. It saves energy, increases production efficiency, and protects personnel in industrial safety.
