Double layer panels |
 |
|
The double layer panel is aimed at ensuring natural lighting for roofing and cladding buildings insulated with double layer panels.
 Double layer panels are made from two plaques of polycarbonate joined together with inline seals made from high-density polyethylene. Inline seals are hot glued in the factory. The panel is closed laterally with moulded edge strips.
The thickness of the upper plaque is of 1.0 mm and that of the lower cellular plaque 4 mm.
