Pavaroof
System description
Avilion Pavaroof Pitched roofing system is for pitched roofs above 10° with vented roof coverings of all sorts. The Pavaroof Pitched system uses a water resistant interlocking woodfibre board over the rafters in an unbridged layer, to provide a highly insulated roof both thermally and acoustically. The system does not require either a membrane over the outside or any vapour barrier internally. Avilion provide natural hygroscopic high performance insulations as infill insulation, as well as clay boards and environmental paints as internal options.

System Application
Avilion Pavaroof Pitched Roofing System is particularly suitable for rooms in roofs and other applications where there can be problems with summer overheating or with external noise pollution. Since it is usual to live in the roof space in France, rather than to have a full loft, this is of particular benefit in regions that experience extremes of hot and cold weather.
System Benefits:
- Excellent thermal performance, with very low thermal bridging (y values), enabling slim construction for new Part L compliance
- Excellent windtightness
- Excellent acoustic insulation
- Excellent overheating control
- Fully breathing construction
- Robust and easy system to install
- Tried and tested system, fully certified
Full System Components
Environmental Performance:
- BREEAM Green Guide rating: A
- Carbon positive (locks up more than is used) and non toxic Woodfibre Boards are over 95% waste
- Insulation boards: Interlocking, waterproof Isolair boards (22, 35, 60mm) and Pavatherm Plus boards (60, 80, 100mm).
- Tapes and Glues: Pavatape for exposed edges, valleys, hips, ridges, service penetrations etc. Also special glues for board edges on pitches between 10°and 20°. On pitches over 20° board edges are not glued.
