CERAMIC FIBRE BOARD
Refractory ceramic fibre board is a vacuum formed product that resists higher gas velocities than ceramic fibre blanket. It is ideal for furnace, boiler duct and stack lining due to its low thermal conductivity and low heat storage allowing shorter cycle times and quicker access for maintenance.
Examples of Applications:
Key Features:
• Refractory lining for industrial furnaces in walls , roofs, doors, stacks etc • Combustion chamber liners, boilers and heaters • Back-up insulation for brick and monolithic refractories • Transfer of molten aluminium and other non-ferrous metals • Expansion board joints • Barrier against flame or heat • Hot face layer for high velocity or abrasive furnace atmosphere
• Low thermal conductivity • Very low heat storage • Light weight. Replaces heavy back-up insulation, less steel required • Excellent thermal shock resistance • Resistant to hot gas erosion • Resists most chemical attacks • Easy to cut, handle and install • Low sound transmission • Resists penetration by molten aluminium and other non-ferrous metals • Contains no asbestos
