Vapour control membrane
The Eurovent AKTIV is two - layer ac tive vapour control. Made of one layer of polypropylene nonwoven and functional film which controls the transfer of vapour towards the attic or towards the inside of the building and, if necessar y, from the attic to the inside too . The active properties of the membrane consist in supporting mo isture removal, which is not ensured by regular vapour barrier films. The membrane is available in the SYSTEM SK2 with two self - adhesive tapes
The Eurovent AKTIV vapour control membrane is used in residential and industrial construction as a vapour control layer protecting the attic against excessive moisture penetration from the inside of a room to thermal insulation . Thanks to its active properties , it prevents, among other things, the effect of a "foil bag", i.e. the formation of fungi and moulds in the attic as a result of excessive moisture . It p rotects structural timber from decay. When installing it, it is strongly recommended to use the Eurove nt® DUO adhesive tape to glue subsequent overlaps and to seal joints with the roof construction elements.
