❓ Frequently Asked Questions
Q1
What is the rupture strength of the Forest Calcium Silicate Board?
The board achieves a rupture strength of 8.1 MPa, which significantly exceeds the standard requirement of ≥4 MPa, ensuring excellent structural durability and load-bearing capability in a wide range of building applications.
Q2
What fire rating does this calcium silicate board carry?
The board has achieved an A1 non-inflammability rating — the highest fire resistance classification — making it an ideal choice for fire-safe interior and exterior building applications.
Q3
What thicknesses and sizes are available?
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 to meet specific project requirements.
Q4
What density options are offered?
Two density grades are available: the Common Type with a density of 1.2–1.5 g/cm³ for standard applications, and the High-Density Type with a density of 1.6–2.0 g/cm³ for applications requiring greater strength and impact resistance.
Q5
What surface treatment options are available?
Two surface treatment options are offered: a non-belt sanded finish (with optional front-side belt sanding), and a front-side belt sanded finish with optional chamfering. These options allow flexibility for different installation and aesthetic requirements.
Q6
How moisture-resistant is this board?
The board's moisture expansion rate is only 0.19%, well below the standard threshold of ≤0.25%. This low expansion rate ensures dimensional stability in humid environments, making it suitable for bathrooms, kitchens, and other moisture-prone areas.
