Ceramic Fiber Board

What is Ceramic Fiber Board?

Ceramic Fiber boards  provide a rigid solution for ceramic fiber insulation. Our Ceramic Insulation Boards are manufactured through a wet forming process using alumina-silica fibers and binders. Standard Ceramic Insulation Board grades are standard, high purity, and zirconia. Boards are available in a variety of temperature ratings, dimensions, and custom vacuum-formed shapes. If you are looking for a ceramic fiber board not listed or custom fabrication, please contact us directly.

Low Density Ceramic Fiber Board Vs. High Density Ceramic Fiber board

Low density Ceramic Fiber Insulation boards are slightly better insulators, but they are not as durable and heavy as high density. Our office always recommends high density when drilling, machining, or rigidizing ceramic fiber boards. If you have further questions in regards to your specific application, contact us.

Stocking Locations

Our Boards are available domestically and internationally. Some of our domestic locations are listed below, please note that inventory and pricing may vary. Full pallet orders do qualify for 10% discounts. Please contact us directly for this option.

Benefits

  • 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.
