CFS Building Material Silica Rock Sandwich Boards

Siliceous rock board is a high-quality fireproof, thermal insulation board made of siliceous rock cement and fly ash as cementitious materials, supplemented with modified polystyrene particles, diatomite, sepiolite powder and other light fillers, adding functional additives, mixing, foaming, covering the surface with alkali resistant glass fiber cloth, pressing, curing, cutting and other processes.Siliceous rock Composite Sandwich Panels has excellent fire prevention and thermal insulation performance, high strength, strong bearing capacity and light plate.

Silicalite board is mainly made of polystyrene, which is originally an excellent low thermal conductivity raw material, supplemented by extrusion to form a compact honeycomb structure, so as to effectively prevent heat conduction. The thermal conductivity of polystyrene board is 0.028 / m.k, which has the characteristics of high thermal resistance and low linear expansion. The thermal conductivity is much lower than that of other thermal insulation materials. At the same time, the board has light material, low price and stable chemical and physical structure, which can ensure the durability and stability of the thermal insulation performance of the material. Therefore, it is one of the excellent thermal insulation materials in the world.It can be used for Cold formed steel buildings.
