For sloped roofs, the roofing is done using sandwich panels, providing a durable and cost-effective solution. Similarly, to the wall cladding, the sandwich panel for the roof covering consists of inner and outer steel sheets with an insulating core of PIR or mineral wool. Therefore, additional insulation is not necessary.
The upper shell is also resistant to fire sparks and radiant heat (hard roofing according to DIN 4102, Part 7). The sandwich panels are fastened to the high bead using stainless steel screws and calottes. The stability of the panels allows additional installations such as photovoltaic systems.
