Refractory Ceramic Fiber

Refractory ceramic fibers have heat-resistant properties and are an excellent material for heat-resistant insulation. Ceramic fiber comes in several different forms and can be used for numerous applications. Here are some fast facts about refractory ceramic fiber:


  • Extremely resistant to chemicals.
  • Typically used in temperatures from 1100°F to 2600°F.
  • Also known as High-Temperature Insulation Wool (HTIW), Kaowool, or Ceramic Fiber Wool (CFW) depending on chemical makeup.
  • Made of calcined kaolin clay OR a combination of Alumina and Silica, with small amounts of Zirconia in some.
  • Can be shaped and bonded into a variety of shapes and textures.

Types & Uses

  • Ceramic Fiber Blanket – Used in direct exposure to flames.
  • Cloth – Commonly used in architecture for fire doors, furnace & insulation.
  • Ceramic Fiber Module – A ceramic fiber blanket that is accordion folded and compressed to a required density.
  • Rope – Ceramic fiber rope can be used to support or attach various heat-resistant structures.
  • Paper –  Ideal for various insulation purposes, such as covering gaskets to hold in high temperatures.
  • Additive – Common in various architectural structures, such as heat-resistant roofing or walls.
