Features of Calcium silicate board:

1. Fireproof: It is flame resistant to combustion at 800 and remains flameless at1200. Non-flammability: National Standards GB8624 Grade A. 
2. Humidity Resistance: The board still keeps Intact after being soaked in water for one month, the phenomenon of swelling and out of shape will Not happen. It will Not disintegrate when Immersed in water or exposed to freeze/thaw cycles for prolonged periods of time. 
3. High Strength: The strongest one among the inorganic thermal insulation materials with the similar density. 
4. Heat Insulation: Lower thermal conductivity than other hard mass thermal insulation material. 
5. Pressure tolerance, and acid resistance.
