Fiberwall® Bonded Module Systems – Bonded 30

Fiberwall® Bonded 30 modules are designed for hot face veneering over existing refractory linings at temperatures up to 1538°C (2800°F). The felt used in Bonded 30 modules is made from a 50-50 blend of Fiberfrax® high-purity bulk fibers and Fibermax®, a polycrystalline mullite fiber patented by Unifrax. The use of Fibermax in the felt formulation produces a product which exhibits extremely low shrinkage at elevated temperatures.

Bonded modules are typically mortared into place over existing refractory using .908 kg to 1.36 kg (2 to 3 Ibs) of Fiberstick refractory cement per module. This lining over refractory (or veneering) approach not only increases the efficiency of the refractory lining but helps to protect it from further degradation.

Advantages of Fiberfrax Ceramic Fiber Veneer:

  • Lower heat losses
  • Reduction in overall heat storage
  • Faster heat up and cool down cycles
  • Lower installation cost
  • Easy repairs
  • Thermal shock resistance
  • High heat reflectance
  • Good sound absorption
  • Excellent corrosion resistance

Typical Veneering Applications:

  • Forge furnaces
  • Refractory kilns
  • Reheat furnaces
  • Pyrolysis furnaces
  • Ceramic kilns
  • Boiler fire boxes
  • Brick kilns
  • Heat treating furnaces
