Calcium silicate boards are made from high-purity quartz sand, slaked lime, and cellulose fiber, cured under high-pressure steam (autoclaving). This results in a dense, durable, and highly stable panel with superior performance in fire resistance, moisture resistance, thermal insulation, and sound absorption. They are completely asbestos-free, non-toxic, non-combustible (Class A1), and dimensionally stable. With smooth or lightly textured surfaces, they can be finished with paint, wallpaper, tiles, or other coatings, depending on the design requirements. Their resistance to warping and decay makes them particularly suitable for long-term use in humid or fire-sensitive areas.

Calcium silicate boards are widely used in interior wall and ceiling systems, especially where fire protection and moisture resistance are key. Common applications include partition walls in office buildings, hospitals, schools, shopping malls, industrial plants, and residential projects. They are also suitable as backing boards for tiles in bathrooms and kitchens. Their fireproof and sound-insulating properties make them ideal for high-traffic and high-risk areas. Lightweight and easy to install with screws or adhesives, they are a popular solution for both new construction and interior renovations.
