JUCOS Refractories > Preheating Insulation Material > Insulation Ceramic Fiber Board
Product Details

Ceramic fiber board is a lightweight refractory material processed with alumina-silica fibers for applications at temperatures up to 1430C. it manufactured and designed for the thermal applications requesting high demands on rigidity, the thermal insulation properties and abrasion resistance of ceramic fiber board have been further improved due to the higher density. 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.
