In the demanding world of industrial thermal insulation, Wedge India stands out as a trusted manufacturer and supplier of high-performance calcium silicate insulation boards, specifically designed for boiler insulation applications. Our boards offer the perfect combination of durability, thermal resistance, and cost-efficiency, making them the ideal choice for industries seeking reliable performance at competitive prices.
Why Calcium Silicate Insulation Board for Boilers?
Boilers operate at high temperatures and require insulation materials that can withstand intense thermal loads while preventing energy loss. Calcium silicate insulation boards are widely preferred due to their:
Excellent thermal stability (up to 1000°C)
Low thermal conductivity
High mechanical strength
Moisture resistance
Non-combustibility and fire safety
These properties make them ideal for power plants, refineries, chemical processing units, and other steam-generating systems.
Wedge® Calcium Silicate Boards – Built for Boiler Performance
At Wedge India, we manufacture our calcium silicate boards using premium raw materials and advanced autoclaving technology to ensure:
Consistent density and low shrinkage
Superior heat retention
Longer insulation life
Dimensional stability under stress
Key Features of Wedge India's Boiler Insulation Boards:
Excellent Thermal Insulation: Minimizes heat transfer, maximizing boiler efficiency.
High Compressive Strength: Can withstand the weight and pressures within boiler casings and systems.
Superior Fire Resistance: Provides an essential layer of passive fire protection.
Moisture and Chemical Resistance: Durable even in the presence of steam or minor chemical exposure.
Easy to Install: Can be cut and shaped on-site to fit complex boiler geometries, reducing installation time and cost.
Available in Various Thicknesses: To meet specific insulation requirements for different boiler sizes and operating temperatures.
Why Choose Calcium Silicate Board for Boiler Insulation?
Boilers operate under high temperatures and harsh conditions, demanding insulation that will withstand heat, moisture, and years of service without compromising performance. Calcium silicate boards excel in these environments due to their:
Superb thermal insulation (low thermal conductivity keeps heat where it belongs)
High mechanical and compressive strength
Exceptional fire resistance (Class A rated)
Moisture and chemical resistance (no warping, swelling, or softening)
Non-asbestos, eco-friendly composition
Long service life with minimal maintenance
