Three layer active vapor barrier membrane. Built of two layers of polypropylene fabric and a functional film that allows small amounts of water vapor to migrate towards the attic from inside the building and, if needed, from the attic to the inside. It can be made to order in a version with two self-adhesive tapes - SK2. The active properties of the membrane are based on the prevention of condensation, which is not provided by ordinary vapor barrier films.
It is used in residential and industrial construction as a vapor barrier layer that protects the attic against the ingress of excess moisture from the interior of the room for thermal insulation. Thanks to its active properties, it prevents, among other things, the effect of a "plastic bag", that is, the formation of attic as a result of excess moisture, fungus and mold. Protects structural timber from rotting. When assembling it, it is absolutely necessary to use Eurovent DUO adhesive tape to glue subsequent plants in and to seal the joints with roof construction elements.
