The rigid polyurethane foam core provides excellent thermal insulation for buildings.
This comes from the excellent thermal conductivity coefficient, λ = 0.022, unparalleled by any mineral wool or EPS sandwich panel. The concealed fasteners mean just that: the joints between the panels are hidden from sight, which improves the aesthetic value of the result.
Besides the superb solidity and durability with a beautiful appearance, the hard polyurethane resin foam used for panels performs quite well in heat insulation.
In times of high energy costs, roof panels with a highly heat-insulating core of polyurethane rigid foam are the first choice. With two layers of hot-dip galvanised and plastic-coated sheet steel and the PU insulating core, this roof panels also meet the highest standards in moisture protection. Additional benefits which stand out are high rigidity and load capacity allowing more distance between supports. In addition, the combination of long panel lengths and low weight facilitates economic construction. Convincing arguments: simple and quick assembly outstanding thermal insulation triple sealing system easy assembly connection principle module width 1,000 mm wide beam and support spacing panel lengths up to 24,000 mm.
