The features of asbestos-free calcium silicate boards are mainly reflected in their environmental friendliness, safety, and excellent performance. As a new type of green building material, it is made from natural raw materials such as high-purity quartz sand, cement, and plant fibers, completely free of asbestos and formaldehyde, making it an ideal choice for ceiling and partition decorations.
What Is Asbestos-Free Calcium Silicate Board?
Asbestos-free calcium silicate boards use siliceous and calcareous materials as the main bonding agents and imported plant fibers as reinforcing materials, refined through processes such as drying and sanding. It not only offers the decorative properties of traditional boards but also possesses unique advantages such as fire resistance, moisture resistance, and environmental friendliness.
Five Key Advantages of Asbestos-Free Calcium Silicate Board Features
01 Fire Resistance and Thermal Insulation
- Non-combustible Class A1 material; does not burn or spread flames in fires
- Provides certain thermal insulation functions and does not produce toxic smoke
02 Water and Moisture Resistance
- Low dry shrinkage and wet expansion rates, excellent weather resistance
- Can be directly used for exterior walls, roofs, and other areas with high waterproofing requirements
03 Dual Environmental Protection
- Made from natural raw materials, free of carcinogens such as asbestos
- No formaldehyde added, eliminating harmful substances from the source
04 Ultra-Long Service Life
- Main raw materials are inorganic, offering mold and insect resistance
- Service life comparable to that of the building itself
05 Stable Performance
- Fibers are specially treated to exhibit a tree-branching structure, enhancing tensile resistance
- Dense internal structure provides lightweight, high strength, and strong plasticity
Application Areas
Asbestos-free calcium silicate boards are widely used in:
- Commercial building ceilings and partitions
- Residential wall decorations
- Baseboards for exterior wall insulation systems
- Specialized boards for humid environments (e.g., bathrooms, kitchens)
