SELF-ADHERING AIR AND WATER-RESISTIVE BARRIER
100% SEAL EVERY TIME HELPS BUILDINGS STAY DRIER AND LAST LONGER.

Conventional barrier products, like bitumen sheets and sprays, are often vapor impermeable or difficult to apply in field conditions. As a result, they can allow air and water leakage due to uneven application. This can lead to air leakage, increased heating and cooling costs, as well as mold and long-term water damage.

Factory-controlled quality of highly vapor permeable DELTA-VENT SA, the only air- and water-resistive barrier with a self-adhering edge lap, ensures every building is 100% sealed. With DELTA-VENT SA, buildings stay drier, save energy, and last longer.
