The water-resistive barrier that’s both air tight and vapor permeable
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 most stringent air tightness requirements when tested per ASTM E2357 (air barrier assembly test), 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.

NFPA 285 is a code-required fire safety test for exterior wall assemblies, but it can be confusing as to which building materials and designs need to comply with the testing standard.

High-performance buildings require insulation, high-quality air- and water-resistive barriers (WRBs), and cladding to achieve air tightness and maximize thermal performance. Some of these envelope materials may be combustible, and therefore the assembly may need to comply with the National Fire Protection Association (NFPA) 285 fire testing standard.
Although NFPA 285 has been a part of the International Building Code (IBC) for several years, the relationship between WRBs and NFPA 285 compliance is often misunderstood. In this on-demand webinar, Dörken’s Product Manager and DELTA® expert Peter Barrett provides clarity on NFPA 285 testing and compliance.
