💡 Frequently Asked Questions
1. What is the fire rating of this fiber cement board?
The board has achieved an A1 fire rating, which is the highest non-combustible classification, ensuring maximum safety for construction projects.
2. How does the board perform in humid environments?
With a moisture content of ≤10% and moisture movement of
3. What are the standard dimensions available?
The most widely used standard size is 2440x1220mm, with thicknesses ranging from 6mm to 24mm to suit different structural requirements.
4. Can I choose different densities for specific applications?
Yes, we provide low (≤1.2g/cm³), medium (1.2–1.5 g/cm³), and high (≥1.5 g/cm³) density options depending on your insulation or strength needs.
5. Why is the board naturally gray in color?
The dark or dull gray appearance is the natural result of its high-quality cement base, providing a neutral finish that can be easily painted or cladded.
6. Is the board strong enough for structural use?
Absolutely. With an anti-bend strength exceeding 16Mpa (and standard requests up to 29Mpa), it provides strong comprehensive strength for walls and flooring.
