Vapor waterproofing Ondulin Barrier D70

Barrier D70 is a polymer fabric laminated with a protective film.

– protects thermal insulation from moisture vapors from inside the building
– protects the roof structure from condensation
– protects the building in case of roof leaks

The Barrier D70 film prevents the wetting of insulation and structural elements, fungal contamination of wooden structures, and corrosion of metal parts. Normalizes the thermal and humidity regime of the structure, reduces heat losses. It contains a UV stabilizer and can be used as a temporary roof for 1 month. Ecologically harmless, not subject to bacterial decomposition.

ASSEMBLING:

The film is mounted on the inside of the insulation plates.

The canvases are mounted with an overlap of at least 10 cm and must be hermetically connected to each other with double-sided or one-sided connecting adhesive tape. Places of abutment to mating surfaces and passage elements are also carefully sealed.

The final fastening is carried out with the help of slats/beams installed along the rafters (spurs), which are nailed to the rafters (spurs).

The gap between the elements of the inner lining and the vapor barrier must be at least 2 cm.
