Which way up is an Onduline sheet fixed? Onduline roofing sheets are easily identifiable by the printed production quality control information applied up the last corrugation on the smooth grained topside (photograph on right).Click to see full answer. Then, how do you apply onduline roofing?Start fixing sheets at the opposite end of the roof from the prevailing winds. Cut a sheet in half vertically and use to lay sheet courses in a broken bond pattern. Only use Onduline PP or Safetop nails on timber; check you have correct side and end sheet laps. Use a string line to keep fixings in line.Furthermore, how do you cut onduline roofing sheets? Cut with an oiled coarse-toothed handsaw or preferably a power tool; such as a circular saw again fitted with a course blade or skill saw. Consult the Onduline Fixing Guide for full instructions. Thereof, how many screws are in a corrugated sheet? Winds can create considerable forces on both the upper surface and the underside of metal roofs. To ensure roofs are secure, our 12 x 50 Class 4 screws are recommended for fixing pierced metal sheeting to timber or metal battens.How much should a corrugated roof overlap?It depends on if you mean side to side or end to end. If side to side, at least 1 ridge. If end to end, overlap 3-6 inches.
