The high temperature calcium silicate core for fireproof and sound insulation door has the characteristics of lightweight. high temperature calcium silicate core is a kind of inorganic material with stable physical and chemical performance of high resistant temperature, low thermal conductivity good effect of insulation for fire and sound-proof, low bulk density, high specific strength and never deformed. The Core can be pieced together arbitrarily and no asbestos absolute.
The cores will not sent out any irritant smoke and gas when burned in high temperature. It is a pure green building material. So it is suitable for fireproof and sound insulation door. The calcium silicate board can be cut, sawed, dug and nailed easily, then assembled at worksite without environment pollution. All this can be done together with other procedures such as piping erection, exhaust system, electric wire installation and so on, easy and high efficient. Free from asbestos.
