Our vacuum-formed ceramic fiber panels are a high-strength, rigid insulation solution designed for applications requiring exceptional thermal stability up to 1800°C. Made from ultrafine ceramic fibers, these panels feature low thermal conductivity, extremely low linear shrinkage, and excellent resistance to thermal shock and chemical attack. Their uniform density and smooth surface make them ideal for manufacturing precision industrial furnace linings, high-temperature gaskets, heat baffles, and as backup insulation in industrial environments such as steel, petrochemical, and ceramic kilns. The panels maintain structural integrity under continuous high-temperature operation, providing reliable energy efficiency and safety.
