Leadsun Calcium Silicate Board is an asbestos-free thermal insulation product capable of withstanding continuous operating temperatures from 650°C up to 1100°C. It is lightweight, exhibits low thermal conductivity, high mechanical strength, easy installation, reliability, and durability. Available in three grades (650, 1000, and 1100), it is commonly used as backup insulation in steel, petrochemical, ceramic, cement, and glass industries, as well as for fire protection in building construction.
It not only provides energy savings but also enhances production efficiency and personnel safety in industrial environments. In housing construction, it is also used for ceilings, fireproof and heat insulation walls, and decorative sound absorption materials.
