❓ Frequently Asked Questions
Q What is the fire resistance rating of this glass wool product?
This glass wool product achieves an A1 non-combustibility rating, which is the highest fire resistance classification. It meets strict standard requirements and has been confirmed through independent testing.
Q What water repellency rate does this glass wool achieve?
The product achieves a water repellency rate of 99.5%, which exceeds the standard requirement of ≥98%. This makes it highly suitable for environments where moisture resistance is essential.
Q What thickness options are available for this glass wool board?
The glass wool boards are available in multiple thickness options: 30mm, 50mm, 80mm, 100mm, 120mm, and 150mm, allowing flexibility to meet different thermal and acoustic insulation requirements.
Q What density options are offered, and how does density affect performance?
Two density options are available: 120 kg/m³ and 140 kg/m³. Higher density boards generally provide better sound absorption and mechanical strength, while both options deliver excellent thermal insulation performance.
Q What is the standard board size for this glass wool product?
The most common board size is 1200mm (length) × 600mm (width), which is a widely accepted standard dimension compatible with most construction and insulation installation systems.
Q What is the heat conductivity coefficient of this glass wool, and why does it matter?
The tested heat conductivity coefficient is 0.039 W/(m·K), which is below the standard requirement of ≤0.04. A lower coefficient means better thermal insulation performance, helping to reduce energy consumption in buildings.
