Calcium silicate board is mainly used as high temperature insulation material of pipes and equipments in the electric power, chemicals, metallurgy and communication industry. And in the housing construction it is also used as the ceiling, fireproof and heat insulation materials of wall and sound absorption materials of decoration.
