Product Details
Polyurethane edge sealing rock wool composite board is high-performance composite building materials designed for fire safety, thermal insulation, and long-term durability. These panels use non-combustible rock wool as the core material, with high-strength pre-coated steel plates on both sides, and polyurethane sealing at the edges. This composite structure combines the excellent fire resistance of rock wool with the moisture resistance and structural integrity of polyurethane, simultaneously meeting the requirements of building envelope systems in terms of fire resistance, thermal insulation, sound insulation, and waterproofing.
Polyurethane edge sealing rock wool composite board is widely used in industrial plants, logistics centers, cold storage facilities, clean rooms, and commercial buildings, and specifications can be customized according to different regional building standards and climate conditions.
Product Structure
| Component | Material | Specification |
|---|---|---|
| Outer steel facing | Pre-painted steel (PE/PVDF coated), galvalume/galvanized | 0.5–0.8 mm |
| Inner steel facing | Pre-painted steel | 0.4–0.6 mm |
| Core material | Water-repellent rock wool (basalt-based) | Density 100–140 kg/m³ |
| Edge sealing | Rigid polyurethane (PU/PIR) | Full perimeter sealing |
The rock wool core material is made from natural basalt and other minerals melted at temperatures exceeding 1,450°C, forming a fibrous structure with high water repellency (≥98%) and low slag content. The polyurethane sealing completely covers the edges of the rock wool, eliminating capillary water absorption and ensuring a completely sealed insulation system.

Performance Advantages
Fire Safety – Class A Non-combustible
The rock wool core material meets EN 13501-1 Class A1 non-combustible standards and GB 8624-2012 Class A2 non-combustible requirements. Depending on the board thickness, the fire resistance rating can reach EI 30 to EI 240. For example, 50 mm can reach EI 30, 100 mm can reach EI 60–120, and 150 mm and above can reach EI 180–240. The rock wool core material maintains its structural integrity at temperatures exceeding 1,000°C, does not produce toxic fumes or molten droplets, and forms an effective fire barrier to limit the spread of flames.
Thermal Insulation – Superior to Ordinary Rock Wool Boards
Polyurethane edge sealing improves the overall thermal performance of the board. The thermal conductivity of the rock wool core is ≤0.043 W/(m·K), and the thermal conductivity of the polyurethane edge sealing layer is 0.019–0.025 W/(m·K), which reduces edge thermal bridging and makes the overall heat transfer of the composite board lower than that of unsealed rock wool boards. The specific overall thermal conductivity depends on the board thickness, core material density, and test reports. This performance helps reduce heating and cooling energy consumption throughout the building’s life cycle.
Moisture Resistance and Durability
Unsealed rock wool boards are prone to moisture absorption at the edges, leading to decreased insulation performance and board deformation. Polyurethane edge sealing completely covers the rock wool, with a water repellency ≥98% and a water absorption ≤0.5 g/100 cm², preventing capillary action, maintaining dimensional stability, and extending the board’s service life.
Structural Strength
The compressive strength of the board can exceed 150 kPa. The rock wool fibers are arranged at 90° perpendicular to the steel plate direction, which enhances compressive and shear strength, making it suitable for wall and roof systems with high load-bearing and wind resistance requirements.
Sound Insulation Performance
High-density rock wool core material offers excellent sound insulation. According to ASTM E90 testing, the polyurethane edge sealing rock wool composite board can reduce noise transmission by up to 30 dB, with a sound insulation Rw ≥ 30 dB, making them suitable for manufacturing areas, power plants, and large computer rooms where noise control is required.
Aesthetics and Installation Efficiency
The concealed screw connection system ensures a smooth exterior surface with no visible fasteners, reducing the risk of corrosion at fixing points and extending service life. The tongue-and-groove joint design facilitates rapid installation and reduces on-site labor. The joint structure resists rain, snow, and freeze-thaw cycles, reducing the risk of wall leakage and indoor mold growth.
