Ceramic fiber board can withstand temperatures up to 2600Degree F (1427 Degree C) without degrading or melting. The low thermal conductivity of ceramic fiber boards makes them effective insulators, helping to reduce heat loss and save energy. Ceramic fiber board are rigid and strong, and they can withstand high mechanical stresses and pressure. This has good resistance to thermal shock, which means it can withstand sudden changes in temperature without cracking or breaking.
