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 classification available. Both the standard requirement and the actual testing result confirm A1 grade, meaning the material will not contribute to fire spread under any conditions.
Q
What is the water repellency performance of the rock wool strip?
The rock wool strip has a tested water repellency rate of 99.5%, which exceeds the standard requirement of ≥98%. This makes it highly suitable for applications in humid or moisture-prone environments.
Q
What thicknesses and densities are available?
Rock wool strips are available in thicknesses of 30mm, 50mm, 80mm, 100mm, 120mm, and 150mm. Two density options are offered: 120 kg/m³ and 140 kg/m³, allowing you to select the appropriate specification for your insulation or structural requirements.
Q
Can the rock wool strip be customized in size?
Yes. The rock wool strip is supplied in a strip shape with customizable length and width based on specific panel requirements. The most common standard board size is 1200mm (length) × 600mm (width).
Q
What is the heat conductivity coefficient, and why does it matter?
The tested heat conductivity coefficient is 0.039 W/(m·K), below the standard maximum of ≤0.04. A lower value indicates better thermal insulation performance, helping to reduce energy consumption in buildings and industrial applications.
Q
What does the potassium oxide and sodium oxide content indicate?
The tested content of potassium oxide (K₂O) and sodium oxide (Na₂O) is 3.36, well within the standard limit of ≤5.0. Lower alkali oxide content indicates higher material purity and better long-term durability, particularly resistance to moisture and chemical degradation.
