Vapour barrier foil

AKTIV FR

The Eurovent AKTIV 3 is three-layer active vapour control. Made of two layers of polypropylene nonwoven and functional film which controls the transfer of vapour towards the attic or towards the inside of the building and, if necessary, from the attic to the inside too. The active properties of the membrane consist in supporting moisture removal, which isnot ensured by regular vapour barrier films. The membrane is available in the SYSTEM SK2 with two self-adhesive tapes.

Advantages

  • Active vapour control
  • Tear resistance
  • Heat reflection
  • Fast and easy installation

AKTIV FR

The Eurovent AKTIV 3 vapour control membrane is used in residential, industrial and frame construction as vapour control layerprotecting the attic against excessive moisturepenetration from the inside ofaroom to thermal insulation. It is perfect for attic insulationwith cellulose insulation. Thanks to its active properties, it prevents, among other things, theeffect of a "foil bag", i.e. the formation of fungi and moulds in the attic as a result ofexcessive moisture. When installing it, itis strongly recommendedto use the Eurovent®DUO adhesive tape to glue subsequent overlaps and to seal joints withtheroof constructionelements.
