Frequently Asked Questions
Q
What thickness options are available for the calcium silicate board?
The calcium silicate board is available in a thickness range of 4 mm to 25 mm, making it suitable for a wide variety of building applications, from interior partition walls to exterior cladding systems.
Q
What is the fire resistance rating of this calcium silicate board?
The board has achieved an A1 non-inflammability rating, which is the highest fire resistance classification. This means the material is completely non-combustible and complies with strict fire safety standards for building materials.
Q
What is the rupture strength of this board, and how does it compare to the standard requirement?
The tested rupture strength of this board is 8.1 MPa, which significantly exceeds the standard requirement of ≥ 4 MPa. This indicates superior structural integrity and durability under load-bearing conditions.
Q
Can the board size be customized, and what is the standard size?
The standard board size is 2400 × 1200 mm, which is compatible with most construction and installation requirements. Customized dimensions are also available upon request to meet specific project needs.
Q
What surface treatment options are offered for the calcium silicate board?
Two main surface treatment options are available: a non-belt sanded finish (with optional belt sanding on the front side), and a front-side belt sanded finish with optional chamfering. These options allow flexibility for different aesthetic and functional requirements.
Q
What density types are available, and what are their respective density ranges?
Two density types are available: the Common Type with a density of 1.2 – 1.5 g/cm³, suitable for standard interior applications, and the High-Density Type with a density of 1.6 – 2.0 g/cm³, designed for applications requiring greater strength, impact resistance, and moisture performance.
