The roof supporting structure (framework) is made of cold-formed steel sections to which corrugated sheet panels are mounted. The steel sections are heat galvanized to a total zinc layer thickness of 275 g/m2 (Z-275). The wall panels are zinc-coated on both sides. The front side is provided with a Polyester coating. The colour can be chosen from our standard colour range. The rear side is provided with a coating of primer in the light grey colour. The wall panels are attached using self tapping screws painted in a colour matching that of the panels. The underside of the panelling is finished with an anodised aluminium sill profile.
The wall construction will be installed from the +35 cm level, provided with a parapet.
The wall insulation consists of 100 mm mineral wall blankets with U=0.43 W/m2K coefficient. The insulation blankets are fitted between the wall girts and the wall panels, and are fabricated as follows:
a) a white vinyl layer with a linen pattern emboss, type CF 305; the visible side,
b) a fibre glass scrim reinforcement 5 x 5 mm,
c) an aluminium foil as a good moisture and vapour barrier.
To ensure an unbroken damp proof layer the seams are sealed using a specially folded and stapled seam.
Profiled steel panels may be mounted to the inside of the wall girts for the external system walls, from the level of +30 cm to, for example, 220 cm. The panels are zinc-coated on both sides. The visible side is Polyester coated in a white colour (RAL 9010). The rear side is primer coated in a light grey colour.
