DELTA®-NEOVAP 20

Tear-resistant vapour 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..

Installation of DELTA®-NEOVAP 20

DELTA®-NEOVAP 20 may be installed in vented and unvented pitched roofs either in parallel with or across the rafters. The sheet may be fixed simply and economically with staples or clout nails. DELTA®-MULTI BAND serves to seal overlaps of DELTA®-NEOVAP 20. The DELTA®-TIXX cartridge adhesive is used to make airtight connections between the sheet and smooth surfaces in gable walls, interior purlins, chimneys, etc. On rough walls, seams are made with DELTA®-KOM BAND plus contact bars or with DELTA®-LIQUIXX .
