Our Ceramic Fiber Board is a vacuum-formed refractory material designed for high-velocity and abrasive thermal environments. Made from high-purity alumina-silica fibers, it forms a rigid yet lightweight structure that balances low thermal conductivity with strong physical durability. It is an ideal choice for furnace linings, boiler ducts, and stacks where both energy efficiency and long service life are required.
