Key Features 

  • High Mechanical Strength & Lightweight: Offers excellent mechanical strength while remaining lightweight. Provides strong thermal insulation, easy machinability, and complete non-combustibility.

  • Superior Thermal Insulation: Features a much lower thermal conductivity compared to other rigid insulation materials and conventional silicate insulation products.

  • Non-Toxic & Non-Corrosive: Free from odor and harmful substances; will not corrode pipelines or equipment. Durable enough for long-term and repeated use.

  • High Stability Under Heat & Moisture: Manufactured through high-temperature autoclaving, the boards and pipes resist deformation within the rated temperature range and remain stable even when exposed to moisture.

  • Wide Temperature Resistance: Safe operating temperature up to 650 °C, which is 300 °C higher than ultra-fine glass wool and over 180 °C higher than expanded perlite products.

  • Long Service Life: Delivers stable performance with strong resistance to acids, alkalis, corrosion, moisture, and pests, ensuring long-lasting durability in harsh environments.

Advantages of Calcium Silicate Board

  • Fire Resistance (A1 Rated):
    Calcium silicate board is a non-combustible A1-grade material. In the event of a fire, it does not burn or release toxic smoke, providing a high level of safety for building applications.

  • Excellent Water Resistance:
    The board performs exceptionally well in high-humidity areas such as bathrooms and washrooms. It remains stable without swelling or deformation even under long-term moisture exposure.

  • High Strength:
    Calcium silicate boards offer superior strength— a 6 mm board is significantly stronger than a standard 9.5 mm gypsum board. This ensures solid and reliable walls that are resistant to cracking or breakage.

  • Outstanding Dimensional Stability:
    Manufactured using advanced formulations and strict quality control, the board maintains optimal stability with minimal expansion and shrinkage caused by moisture variations.

  • Thermal & Sound Insulation:
    The board provides excellent thermal insulation; a 10 mm partition offers better insulation performance than a traditional brick wall. It also delivers effective soundproofing, creating a quieter and more comfortable environment.

  • Long Service Life:
    With stable performance, resistance to acids, alkalis, corrosion, moisture, and pests, calcium silicate boards offer long-lasting durability even in demanding environments.
