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

DELTA®-VENT SA vapor permeable air- and water-resistive barrier allows moisture within the building enclosure to escape through the membrane via diffusion, meaning water won’t collect in the spaces between. By allowing moisture to escape, DELTA®-VENT SA eliminates the risk of mold and other costly problems caused by water pooling where it shouldn’t. Its vapor permeability and air tightness make DELTA®-VENT SA ideal for building and maintaining healthy and comfortable interiors while letting moisture out and improving energy efficiency.

The high-performance solution for energy-efficient construction.

A critical component of any energy-efficient building enclosure is reducing potential air leakage points. DELTA®-VENT SA improves the performance of the wall system by fully adhering to the substrate so fasteners are not required, eliminating leaks due to penetration. DELTA®-VENT SA is dimensionally stable and has the most tightly sealed and secure side laps in the industry. Using DELTA®-VENT SA helps builders meet energy efficiency specifications demanded by clients.

High-performance buildings need high-performance materials.

Better building performance depends largely on the building materials used. Using industry-leading technology, DELTA®-VENT SA creates a continuous water-, air-, and weather-tight barrier while staying highly permeable, so your buildings stay dry and last longer. DELTA®-VENT SA helps to reduce building issues and emergency calls, and contributes to longer-lasting buildings, improved occupant comfort, and client satisfaction.

Easier installation means a healthier bottom line.

Designed with applicators in mind, 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, taking the guesswork out of the application process. It’s lightweight, tear free, and works seamlessly with additional accessories in the system. DELTA®-VENT SA comes with clear and comprehensive installation guides and videos and technical documents that help reduce installation time and labor costs.
