Door Core Calcium Silicate Fireproof Board

The high temperature door core calcium silicate board 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 door core calcium silicate board 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.

Our door core calcium silicate board components enable architects and designers to maintain the natural look of real wood while achieving exceptional safety performance – even in the most demanding commercial applications.

Except the calcium silicate boards door core materials, there are some other materials which are widely used as the fire rated door core materials, such as Mgo boards, vermiculite insulation board, perlite boards, composition insulation boards.

We have a wealth of experience in manufacturing cores for fire doors. We know the challenges and possibilities facing the fire door industry both in the sales and manufacturing process.
