FAQ

Frequently Asked Questions

What is fire rated calcium silicate board?
A rigid, non-asbestos calcium silicate board used in passive fire protection. It is a non-combustible material that maintains structural and dimensional stability when exposed to high temperature.
What temperature can it withstand?
Depending on grade and application, the boards are suitable for service up to 1100°C and are widely used for thermal protection and passive fire protection systems.
Which density should I choose?
For fire protection, the high density grades are typically used: 850 kg/m³ for high strength, 980 kg/m³ for industrial fire grade, and 1200 kg/m³ for maximum mechanical performance.
Can boards be machined?
Yes. Boards can be cut, drilled and CNC-machined into cores, panels and shaped components for doors, walls and enclosures.
Do you support custom production?
Yes. We provide custom dimensions, OEM production and export packaging direct from our factory.
