Ceramic Fiber Board Low Density 2300F (2″ X 24″ X 36″)



Low-density ceramic fiber boards provide a rigid solution for high-temperature applications. Low-density boards are slightly better insulators in comparison to high-density. If the boards need to be machined or rigidized for your application, our office always recommends high-density boards.

Shipping Information

Boards are sold per carton and palletized to ship Less Than Truckload (LTL Freight) or via UPS in specially packaged cartons to ensure safe delivery. LTL is recommended for larger orders, and UPS for smaller orders. Please contact us directly for a custom LTL shipping quote or place your order and a CeraMaterials representative will contact you to confirm the shipping cost before processing your order.

Temperature Rating: 2300℉

Grade: Low Density

Density: 16-18lbs/ft³


  • High-temperature stability
  • Excellent strength and hardness
  • Low thermal conductivity, sound transmission, and heat storage
  • Uniform density and excellent resistance to thermal shock and chemical attack
  • Excellent rigidity and modulus of rupture make the boards strong and self-supporting, yet relatively lightweight and easy to cut or machine
  • Resistant to oxidation and reduction
  • Permits fast thermal cycling without cracking or spalling
  • Resists penetration by molten aluminum and other non-ferrous metals


  • Insulating support to brick and castable
  • Furnace hot face lining
  • Industrial heat process equipment insulation
  • High temperature gaskets and seals
  • Flue & chimney linings in furnaces or kilns
  • Molten metal trough covers
  • Expansion joints
  • Industrial heat shields and thermal barriers
