Ceramic fiber insulation board provides versatile thermal insulation solutions for a variety of industrial applications. Made from aluminum silicate fibers that can withstand incredibly high temperatures, these boards deliver effective insulation performance while resisting heat damage. Learn more about the features and uses of ceramic fiber boards below.
What is Ceramic Fiber Board?
Ceramic fiber board consists of high purity alumino-silicate fibers bonded with inorganic binders. The fibers give the boards low thermal conductivity while the binders provide structural rigidity. The boards are lightweight and can insulate at temperatures up to 2,300°F.
The most common type is 1260C ceramic fiber board. The 1260°C designation indicates the maximum temperature limit. The fiber mat withstands continuous operating temperature of 1260°C without losing structural integrity. This makes 1260°C board suitable for insulation in furnaces, ovens, kilns, boilers and other hot equipment.
Ceramic fiber boards provide similar insulation properties as ceramic fiber blankets. However, the rigid board construction allows easier installation for applications requiring more robust, self-supporting insulation.
Key Properties of Ceramic Fiber Board
- High temperature resistance – Withstands temperatures up to 2300°F. Maintains insulation value and structure.
- Low thermal conductivity – Effective insulation with low heat transfer through the board thickness.
- Lightweight – Weighs less than 9 lbs/ft3. Easy to install, transport, and work with.
- Low heat storage – Doesn’t absorb much heat energy. Quick cooling after heating cycle.
- Good acoustic insulation – Sound dampening properties reduce equipment noise.
- Resilient – Can undergo repeated heating cycles without damage. Long service life.
- Fireproof – Rated non-combustible per ASTM standards. Improves safety.
- Inorganic – Contains no carcinogens. Safer handling than insulation with asbestos.
Typical Applications Of Aluminium Silicate Ceramic Fiber Board
- Furnace and oven insulation
- Kiln linings and doors
- Duct, pipe, and stack linings
- Boiler insulation
- Fireproofing panels
- High temperature equipment insulation
Ceramic Fiber Board Grades
1260°C boards are the most common grade as mentioned. Higher purity fiber results in increased temperature resistance. Other grades include:
- 1280°C – Contains higher alumina and silica content. Withstands up to 1470°F.
- 1400°C – Highest purity fibers withstand up to 1800°F continuously.
- Aluminum silicate – More economical. Rated for 1100°C/2000°F continuous use.
Installation and Handling
Ceramic fiber boards are relatively straightforward to install using mechanical fasteners or high-temp adhesives. Cutting can be done with standard tools. Proper PPE and ventilation should be used when handling to minimize dust exposure.
With their exceptional thermal performance and durability, ceramic fiber boards deliver versatile, long-lasting insulation across industrial heating applications. 1260C boards serve as a cost-effective solution for most systems.
