Ceramic Fiber Fireproof Insulation Board
Ceramic Fiber Fireproof Insulation Board is a lightweight rigid insulation material designed for high-temperature thermal protection and fire-resistant applications. Manufactured from alumina-silica ceramic fibers, the board offers low thermal conductivity, low heat storage, good dimensional stability, and excellent resistance to thermal shock.
Its rigid structure makes it suitable for applications where flexible insulation materials are difficult to install. It can be used as furnace insulation, heat shielding, refractory backup insulation, and thermal barriers in industrial equipment operating at elevated temperatures.

High-Temperature Insulation Applications
Mindelun ceramic fiber board is suitable for a wide range of industrial thermal insulation applications, including:
- Industrial furnace walls and roofs
- Heat treatment furnaces
- Cement and rotary kilns
- Ceramic and glass kilns
- Steelmaking and metal processing furnaces
- Furnace doors and covers
- Combustion chambers
- Burner insulation
- High-temperature ducts and flues
- Chimney insulation
- Heat shields
- Refractory backup insulation
- Thermal barriers for industrial equipment
For demanding furnace applications, industrial furnace insulation can be designed using ceramic fiber board together with other refractory insulation materials.
Why Use Ceramic Fiber Insulation Board?
Unlike flexible ceramic fiber blanket, the rigid board maintains a defined shape after installation and provides a stable insulation surface. This makes it particularly useful for flat furnace surfaces, furnace doors, heat shields, and backup insulation systems.
Its low thermal conductivity helps reduce heat transfer, while its low heat storage characteristics can help improve furnace heating and cooling efficiency. The material can also be fabricated into different shapes when standard boards cannot meet the installation requirements.
For flexible or irregular surfaces, Mindelun also supplies ceramic fiber thermal insulation blanket.
