Product Description
High Temperature 1260°C-1430°C Ceramic Fiber Board for Furnace Boiler Kiln Insulation
Product Overview
Our Ceramic Fiber Board is a vacuum-formed refractory material designed for high-velocity and abrasive thermal environments. Made from high-purity alumina-silica fibers, it forms a rigid yet lightweight structure that balances low thermal conductivity with strong physical durability. It is an ideal choice for furnace linings, boiler ducts, and stacks where both energy efficiency and long service life are required.

Key Advantages
- Erosion & Velocity Resistance - Performs better than blanket products in high-gas-velocity applications, offering a durable hot-face layer.
- Thermal Efficiency - Low thermal conductivity and low heat storage help reduce fuel costs and shorten cycle times.
- Lightweight - Low density replaces heavier backup insulation, reducing structural support needs and construction costs.
- Easy to Work With - Can be cut and shaped with standard tools for custom fits and quick installation.
- Chemical Resistant - Resists most chemical attacks and acts as a barrier against molten non-ferrous metals like aluminum.
Applications
- Hot-Face & Backup Linings - For walls, roofs, and doors of industrial furnaces, especially in high-gas-velocity areas.
- Process Equipment - Combustion chamber liners, boiler insulation, heaters, and heat recovery systems.
- Metal Handling - Transfer systems for molten aluminum and other non-ferrous metals; flame or heat barriers.
- Infrastructure - Expansion joint packing, stack and duct insulation in demanding environments.
