Frequently Asked Questions
Q
What is the rupture strength of Forest Calcium Silicate Board?
A
The board achieves a rupture strength of 8.1 MPa in testing, significantly exceeding the standard requirement of ≥4 MPa, ensuring excellent structural durability and load-bearing performance.
Q
Is the calcium silicate board fire-resistant?
A
Yes. The board is rated A1 for non-inflammability — the highest fire resistance classification — making it a safe choice for both interior and exterior building applications.
Q
What thickness and size options are available?
A
The board is available in thicknesses ranging from 4 mm to 25 mm. The standard sheet size is 2400 × 1200 mm, and customized dimensions are also available upon request.
Q
What density types are offered?
A
Two density types are available: the Common type with a density of 1.2–1.5 g/cm³, suitable for general building use, and the High-density type at 1.6–2.0 g/cm³, designed for applications requiring greater strength and durability.
Q
What surface treatment options are available?
A
The board can be supplied non-belt sanded or with optional belt sanding on the front side. Front-side belt-sanded boards can also be ordered with optional chamfering for a refined finish.
Q
What is the moisture expansion rate, and why does it matter?
A
The tested moisture expansion rate is only 0.19%, well below the standard limit of ≤0.25%. A low moisture expansion rate means the board maintains its shape and dimensions in humid environments, reducing the risk of warping or cracking over time.
