Tear-resistantvapour barrier for greater safety under the roof and for timber frame structures. Grid-reinforced, translucent, easy to lay.
Thanks to its Sd value of c. 20m, DELTA®-NEOVAP 20 reduces the diffusion flow from inside far enough to comply with the condensation control requirements in winter. DELTA®-NEOVAP 20 is translucent and thus easy to install. Moreover, it may be combined with all DELTA® sarking sheets..
DELTA®-NEOVAP 20 may be laid out either along or across the rafters. Easy and cheap to fix with staples or clout nails. Use DELTA®-MULTI-BAND or DELTA®-INSIDE-BAND to seal overlaps between DELTA®-NEOVAP 20 sheets. Use DELTA®-TIXX for draught-proof seals with smooth surfaces on gable walls, inferior purlins, chimneys, etc. Seals with unplastered walls should be made with either DELTA®-KOM-BAND and contact bars or DELTA®-LIQUIXX.
