Start laying sheets over the gutter with 7 cm overhang maximum. Installation could be realized either on full deck (recommended) or on discontinuous support (37 cm between purlins).
15 fixings minimum should be used per sheet. The fixing, always set in the top of corrugations, should be done in the right order and in between the two overlapping lines. Wait to fix the last corrugation until you overlap it with the next sheet.
Cover the ridge with the standard ridge and fix it on each side of the roof, on top of each corrugation. The direction of the overlap is opposite to the direction of the prevailing winds.
Lay sheets in the opposite direction to 6 the prevailing winds. Stagger the rows, by starting the second row with a half sheet. Ensure easily the waterproofing by aligning the two overlapping lines.
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.
ONDULINE EASYFIX sheets provide an attractive, colored and long lasting finishing to a wide variety of garden buildings.
