Product Overview
Description
1000 degree fireplace used calcium silicate fireproof board
Calcium silicate fireproof board is mixed with xonotlite and reinforced glass fibre with high service temp. (1050℃), good heat insulation, low bulk density, high strength, good durability and so on.
Product Characteristics:
l Good durability, can bear high temperature within the limit of continuous heat load.
l Low thermal conductivity, in the whole range is used with unmatched adiabatic performance.
l Light weight, high strength. It is the highest in these hard thermal insulation products.
l Better durability, use for a long time without powder.
l Construction with ordinary carpenter applicability, tools can be optional to cut products.
l Used safety, hygiene. Excluding asbestos, sulfur, chlorine such poisonous substances.
l Fear water, but after drying also can be used.
