Calcium Silicate Board Calcium Silicate Board is a high-performance construction material composed of fine silica, cellulose fibers, additives, and Portland cement. It is known for its superior fire resistance, thermal insulation, and soundproofing capabilities. Compared to plywood, gypsum board, MDF, and other wood composite boards, calcium silicate boards offer enhanced durability and resistance to moisture, heat, and termites. These boards are widely used for wall paneling, drywall partitions, and false ceilings in both residential and commercial projects. Their weatherproof nature makes them suitable for interior and exterior applications. Additionally, they are eco-friendly, asbestos-free, and non-toxic, ensuring safety and sustainability in modern construction.
