❓ Frequently Asked Questions
Q
What is the fire rating of this fiber cement board?
This fiber cement board achieves an A1 fire rating, the highest non-combustible classification. Both the standard requirement and the actual testing result confirm A1 performance, making it suitable for fire-sensitive construction applications.
Q
What thickness options are available for this fiber cement board?
The board is available in thicknesses ranging from 6 mm to 24 mm, providing flexibility for a wide range of interior and exterior construction applications.
Q
What density grades are offered, and how do they differ?
Three density grades are available: Low (≤1.2 g/cm³) for lightweight applications, Medium (1.2–1.5 g/cm³) for standard use, and High (≥1.5 g/cm³) for applications requiring superior strength and durability.
Q
What is the standard panel size of the fiber cement board?
The most widely used standard panel size is 2440 × 1220 mm, which is compatible with common construction and cladding layout requirements, minimizing waste and cutting effort on site.
Q
How does the moisture content of this board compare to industry standards?
The industry standard requires a moisture content of ≤20%. This fiber cement board achieves a tested moisture content of ≤10% — significantly better than the requirement — ensuring greater dimensional stability and reduced risk of warping.
Q
Is the dark gray color of the board a quality concern?
No. The dark/dull gray appearance is a natural characteristic of the cement base used in manufacturing. It does not affect the board's structural or fire-resistant performance. The surface can also be painted or finished to match various design requirements.
