Calcium Silicate Board

Laurel Industrial calcium silicate board is a high-performance composite material made from silica, calcium oxide, and reinforcing fibers, cured under high pressure and steam. Renowned for its fire resistance (up to 1100°C), thermal insulation, and dimensional stability, it’s widely used in industrial equipment (boilers, furnaces), construction (fireproof partitions, ceiling systems), and marine applications. Its lightweight yet robust structure ensures easy installation, while chemical resistance and non-toxic properties make it ideal for harsh environments. Eco-friendly and compliant with international standards, it balances durability, safety, and cost-effectiveness across diverse sectors.

Laurel’s calcium silicate board provides superior fire resistance and insulation for industrial kilns, power plants, and petrochemical systems.

Product Details







Calcium silicate board is a high-performance Insulation Board widely used in thermal insulation systems for industrial equipment and buildings. As a reliable calcium silicate insulation board, it offers low thermal conductivity, high compressive strength, and excellent fire resistance, making it ideal for high-temperature applications.

Our calcium silicate board is manufactured using advanced production processes and high-quality raw materials to ensure consistent performance. This Insulation Board features excellent dimensional stability, moisture resistance, and long service life even under harsh operating conditions. Compared with traditional insulation materials, calcium silicate insulation board provides better energy efficiency and improved safety.

As a professional calcium silicate board manufacturer, we supply a wide range of specifications to meet different temperature and density requirements. Our products are suitable for use in boilers, power plants, petrochemical facilities, and kiln insulation systems. Each calcium silicate board is carefully tested to ensure it meets international quality standards.
