High density calcium silicate board, also known as the porous calcium silicate board, is a fiber-reinforced calcium silicate board, with silicon oxide, calcium oxide, and the reinforcing fibers as the main raw materials, made through mixing, heating, gelling, molding, autoclaving and drying processes. Calcium silicate board is a new type of rigid insulation material.
