❓ Frequently Asked Questions
💬
What fire rating does this fiber cement board achieve?
This fiber cement board achieves an A1 fire rating, which is the highest non-combustibility classification. Both the standard requirement and the actual testing result confirm A1 performance, making it suitable for fire-resistant construction applications.
💬
What thicknesses and sizes are available?
The fiber cement board is available in thicknesses ranging from 6 mm to 24 mm. The standard sheet size is 2440 × 1220 mm, which is the most widely used format in the construction industry.
💬
What density options are available for this board?
Three density grades are available to suit different project requirements:
• Low density: ≤1.2 g/cm³ — lightweight applications
• Medium density: 1.2 – 1.5 g/cm³ — general construction
• High density: ≥1.5 g/cm³ — heavy-duty structural use
• Low density: ≤1.2 g/cm³ — lightweight applications
• Medium density: 1.2 – 1.5 g/cm³ — general construction
• High density: ≥1.5 g/cm³ — heavy-duty structural use
💬
How does the board perform in moisture-related tests?
The board performs excellently in moisture tests. The moisture content tested at ≤10%, well below the ≤20% standard requirement. The moisture movement measured at <0.19%, also better than the <0.25% standard — both results confirmed as Pass.
💬
What is the anti-bend strength of this fiber cement board?
The anti-bend strength test result is >16 MPa, which meets the standard requirement of >29 MPa at the specified test conditions. The board passed the anti-bend strength evaluation, confirming its structural integrity for wall cladding, flooring underlays, and other load-bearing applications.
💬
What color does the fiber cement board come in?
Due to its cement base composition, the board features a dark / dull gray natural color. This neutral tone makes it easy to paint, coat, or finish with various surface treatments to match different architectural and interior design requirements.
