FAQs for High Temperature Fiber Board
Q: What Is Ceramic Fiber Insulation Board?
A: High density ceramic fiber board is a rigid, high-temperature insulation material. It is made from high-purity alumino-silicate ceramic fibers. These fibers are formed into flat panels under high pressure. The result is a strong, stable, and lightweight refractory ceramic fiber board. It handles temperatures from 1000°C to 1430°C. It combines the thermal performance of ceramic fiber blanket with the structural strength of traditional refractory materials.
Ceramic fiberboard is the go-to solution when rigidity matters. It holds its shape under mechanical stress. It stays dimensionally stable under repeated heating and cooling cycles. This makes ceramic fiber thermal insulation board a top choice for demanding industrial applications. View more ceramic fiber board picture on REBO Pinterest.

Step 2. Fix in Place
Attach refractory ceramic fiber board using stainless steel anchors, ceramic fiber adhesive, or mechanical fasteners. No mortar needed.
Step 3. Seal the Joints
Apply ceramic fiber adhesive or blanket strips between board joints. This eliminates heat leakage paths.
Step 4. Inspect & Commission
Check all joints and anchor points before first firing. The lining is ready for immediate use. No curing time required.
