Vapor insulation Ondulin Barrier B70
Vapor barrier material used to protect building structures and insulation from water vapor saturation.
The two-layer polymer structure allows you to hold condensate drops for a long time with their subsequent evaporation.
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.
