Ceramic Fibre Boards

Ceramic Fibre Boards

Ceramic fibre boards are manufactured from inorganic amorphous glass fibre that is designed to operate at temperatures up to +1260°C. This refractory material is asbestos free, lightweight and offers excellent resistance to chemicals, gasses and thermal shock. Ceramic fibre boards are easy to install and provide low thermal conductivity and heat storage. They also provide excellent resistance to high temperatures and are commonly used as a lining for furnaces, boiler ducts and stacks.
