Company Profile

Thermal Insulation Ceramic Fiber Board Lightweight Refractory Insulation Material

Excellent Thermal Insulation Ceramic Fiber Board Manufacturer And Supplier

Leadsun ceramic fiber board is a lightweight refractory insulation material manufactured from high-purity alumina-silica fibers, designed for high-temperature applications up to 1430°C (2600°F).

Produced through a vacuum-forming process, ceramic fiber board offers greater resistance to high gas velocities compared with ceramic fiber blanket. With its low thermal conductivity and low heat storage, it is an ideal solution for furnace linings, boiler ducts, and stack insulation, enabling shorter heating cycles, improved energy efficiency, and faster access for maintenance.
