To address the health and environmental hazards of traditional asbestos-containing materials, driven by stringent safety regulations and the demand for high-performance, eco-friendly insulation, the building and industrial sectors advanced the development of asbestos-free calcium silicate board. As a product of continuous process improvements and material engineering, this thermal insulation solution is now capable of withstanding continuous operating temperatures ranging from 650°C to 1100°C.
Calcium silicate board was developed as a safe, asbestos-free alternative to traditional thermal insulation materials. It is capable of withstanding continuous operating temperatures ranging from 650°C to 1100°C. Thanks to advancements in material processing, the board offers a combination of lightweight properties, low thermal conductivity, high mechanical strength, easy installation, long-term reliability, and excellent durability. Three standard grades are available—650°C, 1000°C, and 1100°C—making it suitable for use as furnace backup insulation in industries such as steel, petrochemicals, ceramics, cement, and glass, as well as for fire protection in building construction.
