How do I lay the corrugated sheets?
Always work from the eaves towards the ridge and against the prevailing wind direction. The lower the roof pitch, the smaller the purlin distance and the larger the overlap of the corrugated sheets. For a pitch of 7° to 10°, use an overlap of 2 waves on the long side of the corrugated sheet and an overlap of 20 cm on the short side. For higher pitches, an overlap of 1 wave on the long side and an overlap of ±15 cm on the short side is sufficient.
