Calcium silicate board

Calcium silicate board has emerged as an indispensable fundamental material in the construction and decoration sectors due to its exceptional fire resistance, moisture proofing, durability, stability, and environmental performance. It plays a pivotal role in ensuring building safety, enhancing architectural functionality, and extending service life, making it one of the preferred panel materials for modern high-performance buildings.

Applications:

  1. Interior Partition Walls: Widely utilized in non-load-bearing internal partitions for residential, office, hotel, and commercial buildings, particularly in areas requiring fire resistance and moisture protection (e.g., bathroom and kitchen partitions).
  2. Ceiling Systems: The material of choice for fire-resistant and moisture-proof ceilings, available in diverse forms (flat panels, perforated acoustic panels, etc.).
  3. Exterior Cladding: High-density fiber-reinforced calcium silicate boards are commonly employed as building exterior substrate panels, insulation-decorative composite panel surfaces, or base materials.
  4. Flooring Underlayment: Serves as a leveling and moisture-proof base layer for composite flooring systems (e.g., wood flooring, PVC flooring).
  5. Furniture Backing: Used as backing boards and dividers for cabinets and bathroom vanities.
  6. Industrial Applications: Includes ship bulkheads, fire-resistant ducts, pipe wrapping, electric kiln linings, and steel structure fire protection.

Product Features:

  1. Superior Fire Resistance:

Classified as a Class A non-combustible material, it does not ignite or produce toxic fumes when exposed to fire. The material maintains structural stability at high temperatures, effectively preventing flame spread and providing valuable time for evacuation and firefighting. Ideal for firewalls, fire-resistant ceilings, and pipe shaft enclosures.

  1. Excellent Moisture and Water Resistance:

Compared to traditional gypsum boards, calcium silicate boards exhibit enhanced water resistance. They maintain stable performance in humid environments (e.g., bathrooms, kitchens, basements), resisting deformation, mold, and decay (though optimal waterproofing requires proper joint treatment and surface protection).

  1. High Strength and Durability:

The material features a hard texture and high density (standard board density typically ranges from 1.2-1.5 g/cm³, with higher density variants available). It demonstrates good impact and bending resistance, with excellent weather resistance, freeze-thaw resistance, and long service life, while being impervious to insect and termite damage.

  1. Dimensional Stability:

Through high-temperature and high-pressure processing, internal stresses are fully released, resulting in minimal shrinkage, expansion, or warping deformation, ensuring long-term flatness and stability.

  1. Lightweight Properties:

Facilitates transportation, handling, and installation while reducing structural load on buildings.

  1. Environmental Sustainability:

Composed primarily of inorganic minerals, the product is asbestos-free (complying with modern environmental standards) and contains no harmful substances such as benzene or formaldehyde, making it an eco-friendly building material.
