High Light Rockwool insulation board non-combustibleClass A1 thermal acoustic insulationRockwool board for building industry
Rock Wool Insulation Board – Class A1 Non-Combustible Thermal and Acoustic Insulation for Building and Industry
Our Rock Wool Insulation Board is a high-performance thermal and acoustic insulation solution manufactured from natural volcanic rock such as basalt and dolomite. The raw materials are melted at approximately 1500°C and centrifuged into fine fibers, then formed into rigid boards through a controlled process involving pendulum laying, pleating, pressurization, and curing. With density options ranging from 60kg/m³ to 200kg/m³, our rock wool boards deliver exceptional fire resistance, thermal insulation, moisture repellency, and acoustic performance, making them a reliable choice for demanding building, industrial, and marine applications.
Each board is produced under strict quality control protocols, ensuring consistent density, dimensional accuracy, and reliable performance. The material is hydrophobic treated (≥98% water repellence), non-combustible (Class A1), and contains no asbestos or CFCs, providing a safe, durable, and environmentally responsible insulation solution for both indoor and outdoor use.

Why Choose Our Products?
  • Superior Fire Resistance - Class A1 non-combustible material with a melting point exceeding 1000°C. Provides critical fire protection for buildings, industrial facilities, and high-risk environments where fire safety is paramount.
  • Excellent Thermal Insulation - Low thermal conductivity (≤0.040 W/m*K at 25°C) ensures effective heat retention in winter and heat reflection in summer, significantly reducing energy consumption and operational costs.
  • Outstanding Acoustic Performance - Noise Reduction Coefficient (NRC) ≥0.6 effectively absorbs sound and reduces noise transmission, making it ideal for soundproofing in offices, studios, theaters, and industrial settings.
Primary Applications
  • Building Insulation - Thermal and acoustic insulation for roofs, walls, curtain walls, partition systems, pre-fabricated houses, and external cladding systems in residential, commercial, and public buildings.
  • Fire Protection - Fire barriers, fire-rated doors, structural fireproofing, industrial furnace lining, and passive fire protection systems requiring Class A1 non-combustible materials.
  • Industrial Insulation - Thermal insulation for HVAC ducting, boilers, pipelines, storage tanks, equipment enclosures, and poultry farms where temperature control and energy efficiency are critical.
Frequently Asked Questions (FAQ)
Q1: What is the maximum service temperature for this rock wool board?
A: Our rock wool insulation board has a melting point exceeding 1000°C and can withstand continuous service temperatures up to 650°C. For higher temperature applications, please consult our technical team for specific recommendations.
Q2: Is this product suitable for outdoor applications?
A: Yes. Our rock wool board features advanced hydrophobic treatment with ≥98% water repellence, making it suitable for outdoor use. For extended outdoor exposure, we recommend adding a protective cladding or weatherproof finishing to ensure long-term performance.
Q3: How do I select the correct density for my project?
A: Density selection depends on your specific mechanical strength requirements and operating conditions. 60-100kg/m³ is suitable for general building insulation and acoustic applications. 120-150kg/m³ offers balanced performance for most industrial and construction applications. 160-200kg/m³ provides maximum compression and tensile strength for high-load or demanding industrial environments.
