Buy low cost high density aluminium silicate and alkaline earth silicate wool based boards at wedge India. Aluminium silicate board, also known as calcium silicate board, is a type of heat-resistant and fire-resistant building material used in construction and industrial applications.


It is made from a combination of silica, calcium oxide, and alumina, with small amounts of other additives to enhance its properties. The board is manufactured through a process of mixing the raw materials, forming them into sheets, and then curing them under high temperature and pressure.


Key Features & Benefits of Aluminium Silicate Boards:

  • Composition: Aluminium silicate boards typically consist of silica (SiO2), calcium oxide (CaO), alumina (Al2O3), and small amounts of other additives such as fibers or binders. The exact composition can vary depending on the manufacturer and specific product.

  • Properties: Aluminium silicate boards exhibit excellent thermal insulation properties, high fire resistance, low thermal conductivity, and good mechanical strength. They are also resistant to moisture, chemicals, and pests, making them suitable for use in a variety of environments.

  • Applications: Aluminium silicate boards are used in various applications in the construction and industrial sectors, including:

    • Fire protection: Due to their high fire resistance, aluminium silicate boards are used for fireproofing walls, ceilings, and structural elements in buildings.
    • Thermal insulation: The boards are effective thermal insulators, making them suitable for insulating HVAC ducts, pipes, boilers, and other equipment.
    • Acoustic insulation: Aluminium silicate boards can also provide soundproofing and acoustic insulation in buildings and industrial facilities.
    • Industrial applications: They are used in industries such as petrochemical, power generation, metallurgy, and manufacturing for thermal barriers, furnace linings, and insulation in high-temperature processes.
    • Building facades: In some cases, aluminium silicate boards are used as cladding or facades for buildings, providing both insulation and a decorative finish.
  • Installation: Aluminium silicate boards are typically installed using mechanical fasteners, adhesives, or a combination of both. They can be cut and shaped easily on-site to fit specific dimensions and requirements.

  • Advantages: The key advantages of aluminium silicate boards include their fire resistance, thermal insulation properties, durability, low maintenance requirements, and versatility in various applications.

  • Safety: While aluminium silicate boards are generally safe and non-toxic, proper handling and installation practices should be followed to minimize any potential health risks, such as exposure to airborne particles during cutting or installation.

Overall, aluminium silicate boards are valuable building materials known for their thermal and fire-resistant properties, making them essential in enhancing the safety and performance of structures in demanding environments.
