Following Onduline installation instructions is crucial to ensure a longlasting waterproofing. The product warranty will depend on local installation guidelines, as they are adapted to the local climatic conditions and local roofing structures.
In most countries, it is recommended to install ONDULINE CLASSIC under the following conditions:
- For roof pitches from 9% to 17% (5° to 10°), ONDULINE CLASSIC must be installed on full deck (OSB, Plywood...).
- From 17% to 27% (10° to 15°), it is recommended to install ONDULINE with a maximum spacing between purlins of 45 cm.
- Over 27% (15°), ONDULINE can be installed on purlins installed every 61 cm maximum.
