Fireproof Rock Wool Boards from China - Leading Suppliers and Factory for High-Performance Insulation Solutions

Rock wool board, manufactured in China from natural minerals like basalt, undergoes high-temperature melting to achieve outstanding performance. Classified as an A-grade non-combustible material, it boasts a melting point exceeding 1000 degrees Celsius, making it fire-resistant. In the event of a fire, our rock wool boards will not ignite, emit flames, or release toxic substances, ensuring safety and peace of mind. The raw materials are sourced from natural rocks, making them non-toxic and harmless, fully complying with green environmental protection standards. Additionally, these boards provide excellent sound absorption, making them ideal for applications in computer rooms, KTV venues, and meeting rooms that require efficient sound absorption and noise reduction. As a leading supplier and factory of rock wool boards in China, we prioritize quality and environmental sustainability in all our products

    ❓ Frequently Asked Questions
    Q1 What is the fire resistance rating of this glass wool product?
    This glass wool has achieved an A1 non-inflammability rating, which is the highest level of fire resistance classification. It has been independently tested and confirmed to meet or exceed standard requirements.
    Q2 What water repellency rate does this glass wool achieve?
    The tested water repellency rate is 99.5%, which surpasses the standard requirement of ≥98%. This makes it highly suitable for environments where moisture resistance is critical.
    Q3 What thicknesses and densities are available for this glass wool board?
    The glass wool boards are available in thicknesses of 30mm, 50mm, 80mm, 100mm, 120mm, and 150mm. Density options include 120 kg/m³ and 140 kg/m³ to suit different thermal and acoustic performance requirements.
    Q4 What is the standard board size for this product?
    The most common board size is 1200mm (length) × 600mm (width). Custom sizes may be available upon request to meet specific project requirements.
    Q5 What is the heat conductivity coefficient of this glass wool?
    The measured heat conductivity coefficient is 0.039 W/(m·K), which is below the maximum standard requirement of ≤0.04. A lower coefficient indicates superior thermal insulation performance.
    Q6 Is the potassium oxide and sodium oxide content within safe limits?
    Yes. The tested content of potassium oxide and sodium oxide is 3.36, well within the standard requirement of ≤5.0. This ensures the product's chemical stability and long-term durability in various applications.
