Air and vapour barrier DELTA^®-NEOVAP 20

Universal air and vapour barrier with an SD value of approx. 20 m for long-term protection of thermal insulation and roof construction.
Due to its translucency, DELTA^®-NEOVAP 20 is very easy to apply. It is very robust thanks to the grid reinforcement.

It can be combined with all vapor-permeable DELTA^® roofing membranes.

Advantages

Very good processing properties and very good long-term protection of thermal insulation and roof construction
DELTA^®-NEOVAP 20 has an Sd value of approx. 20 m. Thanks to the lattice-reinforcement, the membrane has a high tensile strength of up to 300 N/5 cm. Safe processing thank to high tensile strength and the “boardiness” of the sheet.
Easy application
With its translucency, DELTA^®-NEOVAP 20 is very easy to apply as the rafters are easy to see while applying. The integrated red cross thread at a distance of 10 cm makes a precise cut very easy.

Application

DELTA^®-NEOVAP 20 can be installed on unventilated and ventilated pitched roofs parallel or across the rafters. The coated and printed side always point towards the processor. The membrane can be easily attached with staples or wide-headed nails.

The air and vapor barrier is glued in the overlap area with help of the DELTA^®-MULTI-BAND. On gable walls, purlins, chimneys, etc., the film is attached airtight to smooth surfaces with the cartridge adhesive DELTA^®-TIXX / -TIXX VDR. More detailed work can be done with DELTA^®-LIQUIXX and DELTA^®-FLEXX BAND.
