Details of Pu Roofing Panel

Structural Superiority

- Aerospace-Grade Core: High-density (42±2kg/m³) PU/PIR formulation delivers 0.021W/m·K conductivity - 25% better than industry average.  

- Quad-X Reinforcement: Patent-pending corrugation profile withstands 6.5kN/m² snow loads (EN 1991-1-3 certified).  

- Chemical Resistance: Marine-grade aluminum cladding (HDP coating) survives salt spray for 50+ years (ASTM B117 tested).  

Weatherproof Intelligence

- HydroLock™ Seams: 18° interlocking joints achieve IP68 protection - withstands 300km/h typhoons.  

- Thermal Break Technology: Aerogel-infused edge spacers eliminate cold bridging (ΔT<0.5°C).  

- Fire Safety: EN 13501-1 Class A2 certification without secondary fireproofing.  

Installation Advantages

- SpeedClix™ System: No-tool click-lock assembly enables 55m²/hour installation.  

- Precision Components: Laser-cut panels (±0.5mm tolerance) reduce waste by 30%.

- Adaptive Design: 1200/2400mm widths with curved section capability (5m radius).

2. Compact FlatPack™ (Maximized Container Utilization)  

- Space Efficiency: 22% more panels per 40HQ vs palletized (up to 450m²)  

- Interlock Technology: Non-slip EVA foam layers between panels  

- Transit Security: High-tensile steel strapping (500kg break strength) + air cushion dunnage  

Global Logistics Expertise  

- Ocean Transport: CSC-certified containers with GPS-tracked humidity control (<60% RH)  

- Road Safety: EN 12642 XL-standard load securing for overland haulage  

- Quality Assurance: 5-point pre-shipment inspection (including flatness ≤3mm/m verification)  

Our packaging solutions have delivered over 3 million m² of panels to 37 countries with zero transit damage claims since 2020. Choose Propanel for worry-free logistics tailored to your project scale and budget.

5 RFQS of PU/PIR Roofing Sandwich Panels

 

1. What is the difference between PIR and PU sandwich panel?  

Propanel's PIR panels offer 15% better thermal efficiency (0.02W/m·K) than PU, with higher fire resistance (Class B1 vs B2). PIR's closed-cell structure provides superior moisture resistance for cold storage applications.  

---  

2. What is the disadvantage of a PU sandwich panel?  

Propanel PU panels have slightly lower heat resistance (max +110°C) than PIR. Requires additional fireproofing for certain industrial applications (upgrade to our FR-core option).  

---  

3. What is a PU sandwich panel?  

Propanel PU panels feature polyurethane foam cores (0.024W/m·K) between steel/aluminum faces, ideal for warehouses and commercial buildings needing cost-effective insulation.  

---  

4. What is PIR sandwich panel?  

Propanel PIR panels use polyisocyanurate cores with 180°C heat tolerance, perfect for food plants and pharmaceutical facilities requiring strict thermal/fire standards.  

---  

5. What is PU PIR?  

Propanel's hybrid PU/PIR core combines affordability with enhanced fire performance (EN 13501-1 Class B), achieving 0.023W/m·K thermal conductivity for mid-range projects.  

---  

6. What is the purpose of a sandwich panel?  

Propanel sandwich panels provide structural insulation for roofs/walls, reducing energy costs by 40% in industrial/commercial buildings while speeding up construction 3x.
