The water-resistive barrier that’s both air tight and vapor permeable

After 125 years, we've learned what it takes to protect buildings all over the world in all kinds of weather.

DELTA®-VENT SA is proven to keep buildings dry and comfortable for the life of the building for better building performance, efficiency, and customer satisfaction. It is ABAA evaluated, Building Code Evaluation ICC-ESR 2932 (AC38), meets the most stringent airtightness requirements when tested per ASTM E2357 (air barrier assembly test), is NFPA 285 compliant, Red List Compliant, DECLARE, and has a Health Product Declaration® (HPD 2.0).

DELTA®-VENT SA leads the industry in vapor permeability with a rating of 50 perms. Water-resistive barriers with much lower permeability ratings can trap moisture within the envelope, leading to mold and damage – causing further issues with occupant comfort and health. While keeping external air and water out of the building, DELTA®-VENT SA allows moisture and vapor to escape, for more effective drying

DELTA®-VENT SA comes fully adhered for simple and straightforward application, no fasteners required. With the self-adhesive edge-lap feature, ensuring an airtight overlap is easier than ever, and takes the guesswork out of the application process. It’s lightweight, tear free, and works seamlessly with additional accessories in the system.

DELTA®-VENT SA is the only manufacturer that offers a complete line of application accessories that are chemically compatible, so every corner, window, gap, and edge is 100% sealed, and your building has a continuous envelope. The team behind DELTA®-VENT SA also provides knowledgeable recommendations and Design Logic to solve air and water concerns.
