Rigid thermal insulation
Ceramic Fiber Board
High-density ceramic fiber board engineered for dimensional stability and mechanical strength.

Product overview
Engineered for demanding thermal environments.
Ceramic fiber board is a rigid insulation product formed from high-purity alumina-silicate fibers with inorganic and organic binders selected for the required grade. Its low thermal conductivity and machinability make it suitable for linings, backup insulation and fabricated high-temperature components.
Available specifications are confirmed for each enquiry according to application, quantity and required delivery schedule.
