PU Sealed Rock Wool Foam Compose Panel

PU-Sealed Rock Wool Composite Panel 

Core Structure

The panel features a dense, hydrophobic rock wool core manufactured from volcanic basalt fiber. The core is sandwiched between two steel facings - typically galvanized or pre-painted steel - and the perimeter is fully sealed with high-density polyurethane foam. This PU edge seal eliminates exposed rock wool at joints, preventing moisture ingress, fiber shedding, and thermal bridging at panel connections.

application

In industrial and commercial buildings, these panels are widely used for wall cladding, roof systems, and partition walls, offering exceptional energy efficiency and compliance with fire safety regulations. Cold storage facilities and refrigerated warehouses rely on them for maintaining stable internal temperatures while minimizing heat transfer.

For clean room and pharmaceutical environments, the smooth, sealed PU surface ensures hygienic conditions and prevents dust accumulation. In prefabricated and modular construction, these panels accelerate installation timelines while delivering durable, long-lasting performance.

Their resistance to moisture, mold, and corrosion makes them suitable for coastal and high-humidity regions. Additionally, they serve effectively in transportation hubs, data centers, and sports facilities where temperature control and noise reduction are critical priorities.

With excellent load-bearing capacity and design flexibility

advantages

Fire Resistance Rock wool core is naturally non-combustible, achieving A1/A2 fire ratings. It significantly slows flame spread and withstands temperatures exceeding 1,000°C, meeting strict international fire safety standards.

🌡️ Superior Thermal Insulation The polyurethane foam layer provides outstanding thermal performance with low thermal conductivity, reducing heating and cooling energy costs by up to 30–40% compared to conventional wall systems.

🔇 Acoustic Performance Rock wool's fibrous structure effectively absorbs sound waves, reducing noise transmission between spaces - ideal for factories, studios, and busy commercial environments.

💧 Moisture & Mold Resistance The sealed PU surface acts as a vapor barrier, preventing water infiltration, condensation, and mold growth even in high-humidity or outdoor conditions.

⚡ Fast & Easy Installation Lightweight tongue-and-groove or cam-lock jointing systems allow rapid assembly, significantly cutting labor costs and construction timelines.

💪 High Structural Strength Despite being lightweight, the composite structure offers excellent rigidity and load-bearing capacity suitable for walls, roofs, and ceilings.

🌿 Eco-Friendly & Sustainable Rock wool is made from natural or recycled materials, contributing to green building certifications such as LEED and BREEAM.

🔧 Low Maintenance Durable surface finishes resist corrosion, scratching, and UV degradation, requiring minimal upkeep over a long service life of 25–50 years.

📐 Design Flexibility Available in various thicknesses, widths, and surface finishes (steel, aluminum, or specialty coatings) to suit diverse architectural and functional requirements.
