Ceramic fiber board is a light weight refractory material processed with alumina-silica fibers for applications at temperatures up to 1430C. Ceramic fiber board is a vacuum formed product that resists higher gas velocities than ceramic fiber blanket. It is ideal for furnace, boiler duct and stack lining thanks to its low thermal conductivity and low heat storage, which makes the shorter cycles times and quicker access for maintenance in the industrial furnaces possible.
Ceramic fiber board can be used as lining of high temperature industrial furnaces/kilns, combustion chamber lining of boilers and heaters, transfer part of nonferrous metal furnace.
