Ceramic Fiber Boards: Rigid, High-Temperature Insulation Solutions for Industrial Applications
In industries where extreme temperatures are part of daily operations, selecting the right insulation material is critical for safety, efficiency, and equipment longevity. Ceramic Fiber Boards are among the most reliable insulation solutions, offering a unique combination of rigidity, thermal resistance, and lightweight design.
Designed for demanding industrial environments, these boards provide consistent insulation performance while maintaining structural integrity under high heat.

What Is a Ceramic Fiber Board?
A Ceramic Fiber Board is a rigid insulation product manufactured from high-purity alumina–silica ceramic fibers bonded with inorganic binders. Unlike flexible fiber blankets, ceramic fiber boards offer high compressive strength, making them ideal for areas requiring mechanical stability.
They are available in multiple temperature grades such as 1260°C, 1350°C, and 1430°C, suitable for a wide range of thermal applications.
Key Features of Ceramic Fiber Boards
1. Excellent Thermal Resistance
Ceramic Fiber Boards perform reliably in continuous high-temperature conditions without shrinking or degrading.
2. High Mechanical Strength
Their rigid structure supports equipment loads and resists deformation during operation.
3. Low Thermal Conductivity
Minimizes heat loss, improving energy efficiency and reducing fuel consumption.
4. Lightweight Design
Despite their strength, ceramic fiber boards are significantly lighter than traditional refractory bricks.
5. Resistance to Thermal Shock
Can withstand rapid heating and cooling cycles without cracking.
6. Clean and Safe Insulation
Low dust generation and uniform composition make installation easier and cleaner.
