Calcium Silicate Boards
High-strength, fire-resistant insulation boards engineered for thermal protection, structural stability, and long-term industrial performance.
Why Calcium Silicate Boards Are Used in Critical Applications
Calcium silicate boards are widely used in industrial and building applications where high compressive strength, fire resistance, and thermal insulation are required simultaneously.
Unlike soft insulation materials, calcium silicate boards provide rigid structural support while maintaining reliable thermal performance at elevated temperatures, making them ideal for load-bearing and fire-rated insulation systems.
High mechanical strength
Non-combustible and fire-resistant
Stable performance at elevated temperatures
Long service life in harsh environments
Wedge Calcium Silicate Board Solutions
Calcium silicate board is a high-performance, versatile building material renowned for its exceptional fire resistance, thermal insulation, and long-lasting durability. Engineered from a blend of calcium, silicon, and natural reinforcing fibers, it is completely free from asbestos, making it an eco-friendly and safe choice for modern construction.
Ideal for use in false ceilings, drywall partitions, wall cladding, and specialized industrial applications, calcium silicate board delivers outstanding protection against heat, flames, moisture, and termites. Its smooth, paint-ready surface and excellent dimensional stability ensure easy installation and a flawless finish—whether you’re designing residential interiors, commercial spaces, or demanding industrial environments.
With industry-leading certifications for quality and environmental safety, calcium silicate boards are trusted by architects, builders, and engineers across India for projects where superior fireproofing, insulation, and structural integrity are non-negotiable.
