Pu Sealing Rock Mineral Wool Sandwich Wall Panel

     Engineered for premium performance, our polyurethane-edge-bonded rock wool panels deliver next-generation building solutions. The innovative fusion of high-density rock wool core with precision polyurethane edge sealing creates an unparalleled barrier against heat transfer (thermal conductivity as low as 0.038W/m·K), while maintaining exceptional fire resistance (Euroclass A1 non-combustible). The interlocking tongue-and-groove joint system ensures airtight installation, eliminating thermal bridges. With a compressive strength exceeding 120kPa and water absorption below 3%, these panels excel in harsh environments. Available with factory-applied aluminum foil or steel facings for enhanced vapor barrier and aesthetic flexibility.
