Calcium Silicate Insulation Board
Product characteristics:
Good durability, can bear high temperature, within the limit of continuous heat load,
Low thermal conductivity, in the whole range used with unmatched adiabatic performance.
Light weight, high strength. It is the highest in these hard thermal insulation products.
Better durability, use for a long time without powder.
Construction with ordinary carpenter applicability, tools can be optional cut products.
Used safety, hygiene. Excluding asbestos, sulfur, chlorine such poisonous substances.
Fear water, but after drying also can be used.
