Frequently Asked Questions
Q What is the fire rating of this rock wool strip?
The rock wool strip achieves an A1 non-combustibility rating, which is the highest fire classification available, meaning it does not contribute to the spread of fire under any conditions.
Q What water repellency rate does the rock wool strip achieve?
The tested water repellency rate is 99.5%, exceeding the standard requirement of ≥98%. This ensures excellent moisture resistance in both interior and exterior applications.
Q What thicknesses are available for the rock wool strip?
Rock wool strips are available in a range of standard thicknesses: 30mm, 50mm, 80mm, 100mm, 120mm, and 150mm. Custom dimensions can also be arranged based on specific panel requirements.
Q What density options are offered?
Two density grades are available — 120 kg/m³ and 140 kg/m³ — catering to different structural and acoustic insulation performance requirements.
Q What is the standard board size for rock wool strips?
The most common standard board size is 1200mm (length) × 600mm (width). Custom lengths and widths can be produced based on individual panel or project specifications.
Q What is the heat conductivity coefficient of the rock wool strip?
The measured heat conductivity coefficient is 0.039, which is below the maximum standard requirement of ≤0.04. This low value indicates excellent thermal insulation performance, helping to reduce energy consumption in buildings.
