Ceramic Fiber Bulk


Bulk Fibers are made from high purity Alumina, Silica (and Zircon). They are resistant to chemical attack and are long & flexible with high refractory properties. Simwool Bulk Fibers can be needled to form a blanket, converted into ceramic fiber boards and ceramic fiber shapes, or blended into liquid binders for coatings and cements.




  • Excellent thermal and chemical stability
  • Excellent thermal shock resistance
  • Resilient up to high temperatures
  • Light weight, low heat storage capacity
  • Low thermal conductivity
  • Excellent sound absorber
  • Asbestos free


  • Raw material of secondary ceramic fiber products e.g. blanket, paper, board
  • Expansion joint seal
  • Temporary repair of insulation
  • Loose insulating fill for complex spaces and areas where access is difficult
