YUFENG WOOL® Calcium Silicate Board is an asbestos-free thermal insulation product that can withstand continuous operating temperature from 650ºC up to 1000ºC. The calcium Silicate board are made of nature raw material ,by the reaction of quartz and lime under high pressure , adding strengthen fiber to form, through drying process under high temperature to get the board with various of shape and size . It is light weight, low thermal conductivity, high strength, easy to install, reliable and durable.
There are 2 grades available namely 650ºC &1000ºC which are commonly used as furnace backup insulation in steel, petrochemical, ceramic, cement & glass industry or fire protection in building construction.
It not only provides energy saving, also increases production efficiency. And in the housing construction Calcium Silicate Board is also used as the ceiling, fireproof and heat insulation materials of wall and sound absorption materials of decoration.
