Calcium Silicate Board is a high-performance inorganic building board manufactured from siliceous materials, calcareous materials, and reinforced fibers through advanced high-pressure steam curing technology.
With excellent properties including fire resistance, moisture resistance, dimensional stability, durability, and high mechanical strength, calcium silicate board has become one of the most widely used building materials in modern wall systems, ceiling systems, and prefabricated construction applications.
Compared with traditional gypsum boards, wood-based panels, and other conventional decorative boards, calcium silicate board provides superior strength, better fire performance, and longer service life. It is widely used in commercial buildings, industrial facilities, residential projects, and public construction applications.
As a professional Calcium Silicate Board manufacturer, we operate advanced production equipment and strict quality control systems to ensure stable supply of calcium silicate boards in different sizes, thicknesses, and density grades. We also provide OEM, ODM, and customized engineering solutions for global customers.
What is Calcium Silicate Board?
Calcium Silicate Board is an asbestos-free fiber reinforced inorganic building board.
It is mainly produced using:
Silica materials such as quartz powder, silica sand, and diatomite
Calcium materials such as lime and cement
Reinforcing fibers including cellulose fiber or mineral fiber
Through mixing, forming, pressing, and high-temperature steam curing, the materials undergo a chemical reaction to form a stable calcium silicate crystal structure.
Due to its excellent combination of:
✓ Fire resistance
✓ Moisture resistance
✓ High strength
✓ Lightweight performance
✓ Easy processing capability
Calcium Silicate Board has become a popular choice for wall partitions, ceiling systems, flooring substrates, and fire protection applications worldwide.
