Pavatex-NBT Pavaroof Pitched
pitched roof insulation system
'Burdens Pavatex Pavaroof Pitched roofing system is for pitched roofs above 10° with vented roof coverings of all sorts.
Pavatex Pavaroof system uses 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.
This modern method of construction is time proven, with Pavatex starting production of boards in 1932. The system is ideal for new build, refurbishment and use on historic buildings.
BREAAM Green Guide 'A' rated, and made from waste FSC wood, Pavatex boards lock up more carbon than they cost to produce and are completely non-toxic.
Burdens provide natural hygroscopic high performance insulations as infill insulation, as well as clay boards and environmental paints as internal options.
