Products Description
Polyurethane roof sandwich panels are energy-efficient building panels composed of two metal panels, top and bottom, and a polyurethane rigid foam insulation core in the middle, formed in a single layer using a high-strength adhesive.
They are a leak-proof, cold-bridging-resistant, and high-load-bearing roofing system, making them a preferred material for high-end roofing applications.
I. Product Advantages
1. Multi-dimensional polyurethane roof sandwich panels utilize concealed nails for tight overlap.
2. A unique waterproof groove design effectively prevents rainwater seepage and avoids cold bridging.
3. A 40mm peak height significantly increases the roof panel's load-bearing capacity. While ensuring effective insulation, it effectively reduces construction costs for customers, and roof slopes as low as 3% can be accommodated.
