Discover the ONDUVILLA® difference

The wave of innovation is still moving in full speed ahead. Much more than a product range, ONDUVILLA® is a truly unique roofing solution and a complete system, offering you brilliant aesthetics, reliability and a wide choice of colors and looks.

Light weight

The extremely light weight nature of ONDUVILLA® Tiles ensures that the structural weight of the building can be reduced. ONDUVILLA® ensures significant dead load reduction when compared to traditional tiles. The excellent wind resistance offered by ONDUVILLA® is also a key factor for design.

Water proofing guaranteed

Backed by exclusive SealSmart technology, the elasticity of ONDUVILLA®s composite material allows it to shrink firmly around each nail, creating a permanently leak-resistant barrier.

And the waterproofing is secured thanks to double-embossment technology at the overlaps.

Eco Responsibility

ONDUVILLA® materials are composed of recycled fibers and natural pigments for coloration.

Like all Onduline® products, ONDUVILLA® contains no asbestos.

Installation Procedure

To have a long lasting and guaranteed roof, it is mandatory to follow the fixing order and pattern.

  • ONDULINE® sheet shall be supported by purlins with maximum width distance of 45 cm. Fix the bottom purlins first.
  • 14 screws should be drilled per sheet.
  • 5 screws at each corrugation at the end overlap or eaves.
  • 3 screws at first intermediate purlin of the sheet.
  • 3 screws at second intermediate purlin of the sheet.
  • 3 screws at third intermediate purlin of the sheet.
  • Maximum overhand at eves should be 7 cm.
  • For the end overlap, use minimum 20 cm.
  • For the side overlap, use minimum 1 corrugation.
  • Fasten barge-board level with top of ONDULINE® sheet.
  • The ONDULINE® verge is then overlaid and nailed into position.
  • It is possible to use a ridge element forthis purpose.
  • Use a ridge plank to support the ridge.
  • The ridge element should be fastened at each corrugation of the overlapped sheet.
  • Add an extra purlin when necessary if the distance between the last purlin and the ridge is too wide.
  • Start fixing the ridge element at the opposite end of the roof from prevailing winds.
  • The ridge element should overlap the ONDULINE® sheet minimum 12 cm.
  • Lay ridge elements with a minimum overlap of 12.5 cm.
  • A ridge cap can be cut out of the flat part of a ridge element.


  • Fix valley board / trim purlin and line with ONDULINE® valley.
  • The vertical valley depth should be sufficient to allow the water to flow.
  • The sheets are cut across (parallel to the valley line).
