2 Product Features
Rock Wool Sandwich Roofing Panels with PU Sealing deliver a high-performance roofing solution, blending durability, insulation, and visual appeal. Designed for versatility, these panels excel in challenging environments while simplifying construction.
- Corrosion Resistance: The inner panel can use aluminum foil instead of steel, offering a smooth, attractive surface that withstands high temperatures and corrosive conditions. This makes it perfect for industrial or harsh settings.
- Smart Joint Design: The panels feature a sloped edge at the joints, ensuring a strong, tight fit. This enhances structural integrity and prevents leaks, boosting long-term reliability.
- Thermal Insulation & Fire Safety: With a rock wool core, these panels provide excellent heat insulation and fire resistance. The PU sealing amplifies energy efficiency, delivering a complete, energy-saving roofing option in one installation.
- Superior Strength: The four-wave corrugated design increases resistance to bending and deflection. This allows for fewer purlins, reducing material costs and speeding up construction without sacrificing durability.
- Aesthetic & Cost-Effective: Boasting a bold structural look and a variety of rich colors, these panels enhance building exteriors. Their efficient design cuts material waste, offering an economical yet stylish choice.
