Industrial Ceramic Fiber Insulation Board for High Temp Kilns

Industrial Ceramic Fiber Insulation Board

1260°C Rated | Custom Sizes | High Temp Thermal Insulation for Kilns & Furnaces

Our Ceramic Fiber Insulation Boards are designed for high-temperature thermal insulation in industrial kilns, furnaces, and combustion chambers. Made from high-purity alumino-silicate fibers and formed through vacuum shaping, these boards offer excellent heat resistance up to 1260°C, low thermal conductivity, and outstanding dimensional stability under extreme conditions.

We offer custom thicknesses, dimensions, and densities to match your specific application needs.
