1. The installation of ONDUCLAIR PROTECT is carried out with the ribs (or corrugations) running down the slope of the roof (longitudinal and transversal overlaps).
Horizontal laying direction: Opposite direction of the prevailing wind.
The sheet to be installed covers, along the adjacent longitudinal edge, the sheet installed previously.
Vertical laying direction: From the bottom up. The downslope lap (cut back) of the top sheet covers the lower sheet already installed.
