Ondutile is a unique roof underlay system utilising Onduline PP corrugated roof sheets below tile, slate or shingle roof coverings to create an independent secondary weatherproof roof.
This enables the primary tiled roof to be used safely below the manufacturers minimum recommended roof pitch.
Ondutile minimum recommended roof pitches:
- Interlocking concrete tiles: 12.5°
- Clay pantiles, natural and fibre cement slates: 17.5°
- Plain double lap tiles: 22.5°
The Ondutile low line sheet has been developed with a corrugation height of only 24mm. Providing the same durable weathering performance whilst reducing the roof section making it ideal for projects where height restriction or the aesthetic appearance of the roof line is of paramount importance.
- Immediate weather protection
- Moisture control
- Reduced roof pitch
- Thermal and sound Insulation
- BBA Certification (Ondutile only)
