Lightweight 240kg/m3 Calcium Silicate Board Sound Insulation Water Resistant Fireproof
Fireproof Lightweight 240 Kg / M³ Calcium Silicate Board Sound Insulation Water Resistant Fireproof
Calcium silicate board is an asbestos-free thermal insulation product that can withstand continuous operating temperature from 650C up to 1100C. It is light weight, low thermal conductivity, high strength, easy to install, reliable and durable. There are 3 grades available namely 650 &1000 & 1100 which are commonly used as furnace backup insulation in steel, petrochemical, ceramic, cement & glass industry or fire protection in building construction. It not only provides energy saving, also increases production efficiency and gives personnel protection in industrial safety aspect. And in the housing construction Calcium Silicate Board is also used as the ceiling, fireproof and heat insulation materials of wall and sound absorption materials of decoration.
