SHEETSCERAMIC BASED PRODUCTS
Ceramic Fiber Board (Sheet)
01
Product Description
Ceramic fiber board is a vacuum-formed material capable of withstanding higher gas velocities than ceramic fiber blanket. This material is widely used in furnaces, boiler inlets and outlets, and industrial plant chimney linings. Its low thermal conductivity and low heat capacity allow for quick interventions and rapid maintenance at the location where it is used.
