    ❓ Frequently Asked Questions
    Q What is the fire resistance rating of this rock wool strip?
    This rock wool strip achieves an A1 non-combustibility rating, which is the highest fire resistance classification. It meets and exceeds the standard requirements, making it suitable for applications where strict fire safety regulations apply.
    Q What water repellency performance does the rock wool strip offer?
    The rock wool strip has a tested water repellency rate of 99.5%, exceeding the standard requirement of ≥98%. This ensures excellent moisture resistance and long-term durability even in humid environments.
    Q What thicknesses are available for the rock wool strip?
    The rock wool strip is available in a range of thicknesses: 30mm, 50mm, 80mm, 100mm, 120mm, and 150mm. Custom dimensions can also be arranged to meet specific panel or project requirements.
    Q What density options are available, and how does density affect performance?
    The rock wool strip is offered in two density options: 120 kg/m³ and 140 kg/m³. Higher density provides improved structural rigidity, better sound insulation, and enhanced thermal performance, making it ideal for demanding construction applications.
    Q What is the standard board size, and can it be customized?
    The most common standard board size is 1200mm (length) × 600mm (width). The strip shape supports customizable length and width based on specific panel requirements, offering flexibility for various construction and insulation projects.
    Q What is the heat conductivity coefficient, and why does it matter?
    The tested heat conductivity coefficient is 0.039 W/(m·K), which is below the standard maximum of ≤0.04. A lower coefficient means superior thermal insulation performance, helping to reduce energy consumption and maintain comfortable indoor temperatures.
