SOPRAVAP® VISIO is a translucent vapour barrier / vapour retarder screen with a high resistance to tearing. It can be installed, either on the roof in the traditional way on discontinuous substrate, either on wall on continuous or discontinuous substrate.
IMPLEMENTATION
Installation of an air barrier system: SOPRAVAP® VISIO is horizontally unrolled and stapled on the timber frames. To ensure a better air tightness of the buildings, an overlap of at least 10 cm is required. All overlaps, horizontal and vertical, are grouted continuously with the adhesive AIR'STICK®. A continuous cord of mastic AIR'SOPRASEAL® INT is used to grout SOPRAVAP® VISIO with walls: floor, ceiling and joineries.
Installation of with a blowing machine: SOPRAVAP® VISIO is particularly suitable for the blowing of the cellulose wadding in the holes with a maximum spacing of 60 cm between rafters.
