Good quality Calcium silicate boards high density 1250 - 1300 kg/m³ size of 2440 x 1220 x 5 mm thick at low price 516 INR/Pc at Wedge India. Calcium silicate boards high density 1250 - 1300 kg/m³ size of 2440 x 1220 x 5 mm thick boards are commonly used in building construction due to their excellent fire resistance, durability, and thermal insulation properties. These boards are particularly effective for applications that require robust structural support along with insulation and fire protection. Key Properties:


Fire Resistance

Non-combustible: These boards are non-combustible, providing excellent fire protection. They can withstand high temperatures without breaking down or contributing to the spread of fire.

Fire Rating: Often used in fire-rated partitions and wall assemblies to enhance the safety of buildings.


  • High Density (1250 - 1300 kg/m³): Ensures structural strength and durability, suitable for high-traffic areas and heavy-duty applications.

Moisture Resistance: Resistant to moisture, preventing warping, swelling, or degradation in humid conditions.

Thermal Insulation

  • Low Thermal Conductivity: Provides effective thermal insulation, helping to maintain internal temperatures and improve energy efficiency.

Acoustic Insulation

  • Soundproofing: The dense structure of the board offers good acoustic insulation, reducing noise transmission through walls and ceilings.



1. Wall and Partition Systems

  • Interior Walls: Used in constructing internal partitions to provide fire-rated barriers, sound insulation, and structural integrity.
  • Exterior Walls: Can be used as a sheathing material for exterior walls, providing additional thermal insulation and fire resistance.

2. Ceilings

  • Suspended Ceilings: Ideal for use in suspended ceiling systems in commercial and residential buildings to enhance fire safety and acoustic performance.
  • False Ceilings: Used in false ceilings to conceal mechanical and electrical services while providing fire and thermal protection.

3. Flooring

  • Underlayment: Can be used as an underlayment for floors to provide a stable base and additional fire protection.

4. Roofing

  • Roof Sheathing: Suitable for roof sheathing applications, providing thermal insulation and fire resistance.

5. Fire Doors

  • Core Material: Used as a core material in fire doors to enhance their fire resistance properties.


Installation Considerations

  • Surface Preparation

    • Clean and Dry Surfaces: Ensure surfaces are clean and dry before installation to ensure proper adhesion and effectiveness.
    • Level Surface: The surface should be level and free from any defects that could affect the installation.
  • Cutting and Shaping

    • Tools: Boards can be cut and shaped using standard woodworking tools.
    • Precision: Ensure precise cutting to fit the insulation snugly and minimize gaps.
  • Fixing and Fastening

    • Adhesives: Use appropriate adhesives for securing the boards in place, especially in ceiling and wall applications.
    • Mechanical Fasteners: Screws or nails can be used to fix the boards to framing members or substrates. Ensure fasteners are spaced appropriately to provide secure attachment.
  • Joint Treatment

    • Sealing Joints: Use appropriate jointing compounds to seal joints between boards to maintain fire resistance and prevent air leakage.
    • Reinforcement: Joint reinforcement tapes may be used to strengthen joints and prevent cracking.
  • Finishing

    • Surface Coating: Boards can be painted, plastered, or finished with other surface treatments as required.
    • Maintenance: Regular inspection and maintenance ensure the long-term performance of the boards.



  • Enhanced Safety

    • Fire Protection: Provides critical fire resistance, enhancing the safety of building occupants.
    • Structural Integrity: High-density boards contribute to the structural stability of walls and ceilings.
  • Energy Efficiency

    • Thermal Insulation: Helps in reducing energy costs by maintaining internal temperatures and reducing the need for heating and cooling.
  • Acoustic Comfort

    • Sound Insulation: Reduces noise transmission, enhancing acoustic comfort in buildings.
  • Durability and Longevity

    • Moisture and Weather Resistance: Ensures long-term performance and reduces the need for frequent repairs or replacements.


Calcium silicate boards with a density of 1250 kg/m³ and dimensions of 2440 x 1220 x 5 mm are highly effective for use in building construction. Their excellent fire resistance, durability, thermal and acoustic insulation properties make them ideal for a variety of applications, including walls, partitions, ceilings, flooring, roofing, and fire doors. Proper installation and maintenance are crucial to maximizing their performance and benefits, ensuring enhanced safety, energy efficiency, and overall building performance.
