Frequently Asked Questions
Q
What fire rating does this rock wool strip achieve?
This rock wool strip achieves an A1 non-combustibility rating — the highest fire resistance classification — meeting and exceeding the standard requirement of A1. It has been independently tested and confirmed to pass all fire-related performance benchmarks.
Q
What is the water repellency rate of the rock wool strip?
The tested water repellency rate is 99.5%, which exceeds the standard requirement of ≥98%. This ensures excellent moisture resistance, making the product suitable for use in environments where humidity or water exposure is a concern.
Q
What thicknesses are available for the rock wool strip?
The rock wool strip is available in the following thicknesses: 30mm, 50mm, 80mm, 100mm, 120mm, and 150mm. Custom lengths and widths can also be produced based on specific panel requirements.
Q
What density options are available, and how do they differ?
Two density options are available: 120 kg/m³ and 140 kg/m³. Higher density (140 kg/m³) generally offers improved structural rigidity, better acoustic performance, and enhanced thermal insulation, making it ideal for more demanding applications.
Q
What is the standard board size, and can it be customized?
The most common standard board size is 1200mm (length) × 600mm (width). However, the product is available in strip form and can be customized in both length and width to suit specific panel or construction requirements.
Q
How does the heat conductivity coefficient compare to the standard requirement?
The tested heat conductivity coefficient is 0.039 W/(m·K), which is below the maximum standard requirement of ≤0.04 W/(m·K). A lower coefficient indicates superior thermal insulation performance, helping to reduce energy consumption in buildings.
