Polypropylene vapor barrier EUROVENT® AKTIV ALU

self-adhesive

Three-layer aluminum vapour control. Made of polypropylene nonwoven, functional film and aluminum coating which enables reflection of heat rays 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 Heat reflection Fast and easy installation Tear 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. Reflective surface of aluminum coating allows for reduction of heat loss. It is strongly recommended that the overlaps are tightly sealed with dedicated Eurovent tape.
