Catalouge Waterproofing Membranes

Vapour Barriers
A vapour barrier in the roof prevents any water vapour contained in the room air cavity from getting into the insulating layer and roof
truss. In addition, it optimises the windproofing of the roof construction.

Gefitas®
PE Roof 1/400
With sealing edge
The Gefitas®PE vapour barrier 1/250 consists of a
high-quality, closed-cell 1 mm PE foam and a 250 µm PE
laminate layer. This means that a fleece is no longer required
as an additional layer for rough substrates. The integrated
sealing edge means that the sheets can be easily bonded to
one another. Together with the compatible Gefitas®
accessories, air-tightness is ensured for the vapour-proof
and air-tight joints as per the requirements.
The Gefitas®PE vapour barrier 1/400 is made from a
high-quality, closed-cell 1 mm PE foam and a 400 µm PE
laminate layer. This means that a fleece is no longer required
as an additional layer for rough substrates. The integrated
sealing edge means that the sheets can be easily bonded to
one another. Together with the compatible Gefitas®
accessories, air-tightness is ensured for the vapour-proof
and air-tight joints as per the requirements.
Areas of use
For use on flat roofs for preventing the formation of condensation in wood, steel and concrete constructions.
