Cosella-Dorken Delta-Vent SA

Cosella-Dörken has launched this vapor-permeable, self-adhesive, water-resistive air barrier for commercial and residential use. The Delta-Vent SA effectively combines highly aggressive special adhesives with high vapor permeability to create an air- and water-tight barrier that increases energy efficiency. The barrier eliminates leaks at fasteners and helps improve the performance of the building enclosure. By including a unique self- adhesive edge lap, the Delta-Vent SA also ensures efficiency long after application.
