High Density Ceramic Fiber Board
High Density Ceramic Fiber Board is a rigid ceramic fiber insulation board developed for high-temperature applications requiring reliable thermal insulation, structural rigidity and mechanical strength. Manufactured from alumina-silica ceramic fibers, the board features a uniform structure, low thermal conductivity and good resistance to thermal shock.
Its higher density provides improved rigidity compared with standard ceramic fiber insulation boards, making it suitable for furnace walls, doors, kiln linings and other areas exposed to vibration, airflow or mechanical stress. The board can be cut, drilled and machined to meet different equipment and installation requirements.
Mindelun supplies high density ceramic fiber board for industrial furnace manufacturers, insulation contractors, distributors and industrial users, with customized thickness, density, dimensions and shapes available.

Applications
High density ceramic fiber board is designed for equipment where insulation performance and rigidity are required at the same time.
Typical applications include:
- Industrial furnace walls and roofs
- Furnace doors and covers
- Kiln insulation
- Heat-treatment furnaces
- Boiler and heater insulation
- Combustion chambers
- High-temperature ducts
- Furnace heat shields
- Back-up insulation
- Thermal barriers
- Expansion joints
- Custom high-temperature insulation parts
For complete industrial furnace insulation systems, high density ceramic fiber board can be used together with ceramic fiber blanket and ceramic fiber module according to the furnace structure and operating temperature.
High Density Rigid Ceramic Fiber Insulation
Unlike flexible ceramic fiber products, a rigid board provides a more stable insulation surface and can maintain its shape during installation and operation. This makes rigid ceramic fiber insulation suitable for furnace areas exposed to mechanical handling, airflow, vibration and repeated thermal cycling.
The board’s machinability also allows insulation contractors and equipment manufacturers to produce custom panels, cut sections and special insulation components according to equipment dimensions.
For applications requiring customized shapes, Mindelun can also supply ceramic fiber special shaped products.
