CERAMIC FIBER PRODUCTS
Ultra-lightweight blankets, modules and boards for energy-efficient furnace linings
PRODUCT OVERVIEW
Ceramic fiber products are manufactured from aluminosilicate fibres produced by melting and fiberising a blend of Al₂O₃ and SiO₂. They offer extremely low thermal mass (enabling rapid furnace heat-up and cool-down), very low thermal conductivity, and good resistance to thermal shock. Available in blankets, modules, boards, papers, and loose wool — each suited to different installation requirements.

AVAILABLE GRADES
INSTALLATION NOTES
- 1
Blanket: wrap around cylindrical vessels or layer on flat surfaces — overlap joints by 50 mm
- 2
Modules: attach to shell plate using stud welding — butt joints, no gaps
- 3
Boards: cut with hand saw or angle grinder — wear respiratory protection when cutting fibres
- 4
Expansion gaps: ceramic fiber requires no expansion gaps (it compresses and expands freely)
- 5
Anchoring: stainless steel stud anchors every 300–400 mm for overhead and vertical applications
- 6
Vapour barrier: apply rigidiser or colloidal silica coating on hot face to prevent fibre erosion in high-velocity gas applications
