Kliplock K450 PU 2-rib roofing panel
450 mm width - a folded edge that adds rigidity and seals better
Kliplock K450 PU 2-rib roofing panel
Kliplock K450 roofing panel, 450 mm effective width, PU core at 29 – 38 ± 3 kg/m³, core 16 – 50 mm thick, with a stiffening folded edge.
Product overview
Kliplock K450 is the wider version of the 2-rib interlocking roofing line: 450 mm effective width instead of 400 mm, so fewer joint lines and a shorter roofing programme on a large factory.
The K450 profile adds a stiffening fold at the rib edge, which seals the panel-to-panel joint better.
