Aluminum Silicate Board is a lightweight, high-performance refractory material manufactured from premium alumina–silica fibers. Engineered for thermal applications that require exceptional rigidity and stability, the board is designed to withstand continuous service temperatures up to 1430°C. Its enhanced density gives it superior insulation efficiency, excellent resistance to wear, and improved durability under demanding operating conditions.
Produced through a precision vacuum-forming process, the board offers significantly higher structural strength and better resistance to high gas velocities compared with traditional ceramic fiber blankets. This makes it an ideal choice for furnace linings, boiler walls, duct insulation, chimney systems, and other high-temperature industrial environments.
Thanks to its low thermal conductivity and low heat storage, it helps reduce energy consumption, shortens furnace cycle times, and enables faster access for maintenance. These performance advantages make it a reliable, long-lasting insulation solution for modern industrial furnaces and heat-processing equipment.
