Würth Vapor Barrier WÜTOP® DB 20

Wütop® DB 20 is a diff-capable, airtight and particularly easy-to-install vapour barrier for interior and roof fittings, in conjunction with diff usion-open underlay and underlay membranes. As well as for timber frame constructions with ETICS.

Safety • Extremely resistant, tear and puncture resistant due to the fabric reinforcement. Also ideally suited for blown-in insulation • Prevents the thermal insulation from penetrating the room and thus reducing the insulating effect Technology • 3-layer vapour barrier with fabric reinforcement • Recyclable and therefore ecologically harmless

Universally applicable for roofs, walls and floors.

Time and cost savings through fast processing of the 3 m wide vapour barrier in the prefabrication of timber frame construction elements.
