Maximize project safety with our high-strength, non-asbestos Calcium Silicate Boards. Featuring Class A1 fire rating, superior moisture resistance, and high flexural strength for commercial and industrial partitions. Autoclaved for dimensional stability. Discover our full technical specifications and OEM manufacturing services.
Our Calcium Silicate Board is a next-generation green building material manufactured from high-grade siliceous and calcareous materials. Through a sophisticated process involving high-pressure molding and high-temperature autoclaving (over 180°C), the board develops a unique Tobermory crystalline structure. This chemical transformation ensures exceptional dimensional stability, even when exposed to extreme temperature fluctuations and humidity.
Class A1 Fire Rating: Our board is absolutely non-combustible, blocking heat transfer for up to 4 hours (depending on system design) and generating zero toxic smoke, ensuring clear evacuation routes during emergencies.
Exceptional Moisture & Weather Resistance: Unlike gypsum, calcium silicate does not lose its structural integrity when wet. It resists swelling, delamination, and rotting, making it perfect for high-humidity areas like tropical climates, kitchens, and basements.
Superior Impact & Flexural Strength: With a high density (up to 1.3g/cm³ or higher), the board offers excellent resistance to mechanical impact. It is ideal for high-traffic commercial corridors and industrial environments where durability is paramount.
100% Eco-Friendly & Safe: We guarantee zero asbestos and zero formaldehyde. Our boards are inorganic, mold-resistant, and insect-proof, contributing to healthy Indoor Air Quality (IAQ) and LEED/WELL certifications.
Finishing Versatility: The ultra-flat, sanded surface serves as a perfect substrate for various finishes, including high-grade paints, wallpapers, stone veneers, or ceramic tiles.
