The roof sandwich panel is a building component that is leakage and thermally insulated. They are designed for roof plate systems with great bearing capacity. They are preferred for use on high-end buildings.Construction Effect of PU Sandwiched Roof Panels
1. Duowei polyurethane roof boards use concealed nails for connection and boards are lapped together tightly.
2. Unique waterproof groove design, effectively preventing rainwater leakage and avoiding cold bridge phenomenon.
3. 40 mm corrugation height, greatly improving bearing capacity of roof board and also effectively lowering customer construction cost while ensuring building thermal insulation effect; minimum roof slope can reach 3% .
