Calcium silicate board is a high-strength, lightweight, and fire-resistant material widely used in construction and industrial applications. Produced from a mixture of silica, lime, and reinforced fibers, calcium silicate board offers excellent thermal insulation, moisture resistance, and dimensional stability. Unlike traditional gypsum boards, calcium silicate board performs reliably under both humid conditions and elevated temperatures, making it suitable for demanding environments.
The structure of calcium silicate board offers unique benefits that distinguish it from other panel products. It is non-combustible and capable of withstanding continuous exposure to temperatures up to 1000°C, depending on grade and density. Calcium silicate board also has low thermal conductivity, providing effective insulation in buildings and high-temperature equipment. Another important property is moisture resistance—while many boards lose strength in damp conditions, calcium silicate board maintains integrity, making it suitable for bathrooms, kitchens, and coastal environments.
In terms of mechanical performance, calcium silicate board has high bending strength and impact resistance. This allows it to be used not only as a finishing surface but also as a structural partition wall or ceiling panel. It can be easily cut, drilled, and finished with paint, tiles, or laminates, giving architects and engineers flexibility in design.
Fire resistance: Calcium silicate board is non-combustible and can withstand prolonged exposure to high temperatures.
Moisture resistance: Unlike gypsum boards, it does not soften or warp when exposed to humidity, making it ideal for kitchens, bathrooms, and industrial facilities.
Durability: High mechanical strength allows calcium silicate board to serve as both partition wall panels and ceiling boards in commercial and residential projects.
Thermal insulation: Its low thermal conductivity makes it effective as a lining in furnaces, boilers, and ducts.
Calcium silicate board is versatile and widely applied in:
Building construction: Used for internal partitions, ceilings, wall cladding, and flooring underlay where fire safety and moisture resistance are essential.
Industrial insulation: Installed as lining in furnaces, kilns, and power plants, calcium silicate board reduces heat loss and extends equipment lifespan.
Shipbuilding and offshore platforms: Provides fire-rated partitions and insulation under extreme conditions.
Fire protection: Commonly used in fire doors, tunnel linings, and escape corridors due to its high fire resistance rating.
Contractors and engineers prefer calcium silicate board for its long service life, easy installation, and low maintenance requirements. It can be cut, drilled, and finished with paints or tiles, making it adaptable to both modern architectural design and heavy-duty industrial use.
Calcium silicate board is a preferred material in modern construction where safety and durability are priorities. In commercial and residential projects, it is widely used for partition walls, suspended ceilings, external cladding, and flooring underlays. Because calcium silicate board is non-combustible, it contributes to fire-rated walls and ceilings, improving the safety of buildings. Its resistance to moisture also makes it ideal for areas like bathrooms, basements, and kitchens, where gypsum boards typically fail.
For green buildings and energy-efficient projects, calcium silicate board contributes to insulation performance, reducing energy demand for heating and cooling. Unlike traditional boards, it does not release toxic gases during fire exposure, which adds an extra layer of safety for occupants.
