Description of the Ceramic Fibre Board
Ceramic fibres are produced from high-purity aluminosilicate material using a strictly controlled high-temperature melting and fibre-forming process. The resulting ceramic fibre boards are white and odourless. They are rated for applications at temperatures up to 2300°F. Given that the panels offer high temperature resistance, consistent thermal stability and verifiable energy savings, they are replacing conventional refractory stones. In addition, they offer increased tensile strength and a vacuum-formed felt compared with ceramic matting.
Advantages of Ceramic Fibre Boards
- Faster temperature changes
- Reduced heat retention
- Lower fuel costs
- Increased productivity
- Reduced installation costs
- Simpler repairs
- Resistance to thermal shocks

Applications of Ceramic Fibre Boards
- Refractory linings for industrial furnaces in walls, roofs, doors, chimneys, etc.
- Linings for combustion chambers, boilers and heaters
- Supplementary insulation for masonry and monolithic refractory materials
- Transport of molten aluminium and other non-ferrous metals
- Expansion joint panels
- Barrier against flame or heat
- Hot surface layer for high-speed or abrasive furnace atmospheres
