1. Start installation at eave, in the opposite direction of the prevailing wind. Position the dark strip on top. Stagger the rows, by starting the second row with a half tile. Horizontal overlaps are one corrugation.
Ensure proper waterproofing by aligning the overlapping guides.
Overhang at eave must be maximum 5 cm.
2. Stagger the rows, by starting the second row with a half tile. Ensure proper waterproofing by aligning the overlapping guides.
3. The aesthetics and wind uplift protection can be optimized by using the verge element accessory, which is fixed first on the sidewall, then as well on the top of the corrugation.
4a. Ensure watertightness at ridge by applying the ONDUVILLA FOAM FILLERS, on both sides of the ridge line.
4b. Cover the ridge with the SLIM CAP and fix it on each side of the roof, through the FOAM FILLERS, on top of the corrugations. The direction of the overlap is opposite to the direction of the prevailing winds.
Using ONDULAIR SLIM sealing tape at the ridge will provide complete waterproofing to the roof.
5. Finish the ridge with the CLOSURE CAP element for better aesthetic and better waterproofing.
