DELTA Vent SA

DELTA-VENT SA is a vapor-permeable, self-adhering air- and water-resistive barrier that prevents moisture from getting into buildings while allowing trapped moisture to escape, eliminating the risk of mold and other water-related problems. Its vapor permeability and airtightness make it ideal for healthy, comfortable interiors and energy-efficient enclosures.

The high-performance solution for energy-efficient construction

DELTA-VENT SA improves the performance of the wall system by adhering directly to the substrate - no fasteners are required, eliminating leaks due to penetration. It is dimensionally stable and has the most tightly sealed and secure side laps in the industry, helping builders meet client energy-efficiency requirements.

Easier installation, healthier bottom line

DELTA-VENT SA is designed with applicators in mind: it comes fully adhered for simple, straightforward application without fasteners. Its self-adhesive edge-lap feature ensures airtight overlaps. It is able to resist UV exposure for up to one year.
