Polypropylene vapor barrier EUROVENT® AKTIV 3

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. Unlike in case of vapour-insulation foils, active properties of the membrane which consist in variable Sd value allow to prevent condensation. Membrane is available in SYSTEM SK2 with two self-adhesive tapes. Advantages: Vapour control Tear resistance Fast and easy installation UV resistance Application Membrane is designed for use as vapour control layer to protect thermal insulation against penetration of water vapour. Unique properties of the product allow for active regulation of vapour transfer preventing condensation and damage of wooden constructions resulting from thereof. It is strongly recommended that the overlaps are tightly sealed with dedicated Eurovent tape.
