Vapour Barrier DB 140

The Vapour Barrier DB 140 is an active three-layer vapour barrier. It is made of two non-woven polypropylene fabric layers and one barrier film layer that prevents moisture from entering the roof void or interior of a building and, if required, from entering the interior of a building from the roof void. The membrane acts as a barrier by helping to transport moisture away, which standard damp proofing membranes do not always do.

The Vapour Barrier DB 140 is designed for use as a vapour barrier in residential and industrial construction and protects roof voids by preventing excessive amounts of moisture penetrating into the insulation from the building’s interior. Thanks to its barrier action, the membrane also prevents Advantages
