Pavaroof Application

Pavatex Pavaroof Pitched Buildup

NBT 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 un-bridged 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.

NBT provide natural hygroscopic high performance insulations as infill insulation, as well as clay boards and environmental paints as internal options.
