DELTA®-Vent S / Plus

The DELTA®-VENT S PLUS is a premium, breathable water-resistive barrier designed to protect exterior walls from wind, rain, and snow while allowing interior moisture vapour to escape. This helps prevent condensation, mould growth, and structural damage, ensuring long-term building durability.Featuring integrated sealing strips, DELTA®-VENT S PLUS allows for faster, more reliable installation by creating airtight overlaps without additional tape. It offers excellent UV stability and tear resistance, making it ideal for high-performance residential and commercial applications.DELTA®-VENT S is a highly vapor-permeable WRB, allowing moisture within the building enclosure to escape through the membrane via diffusion. Its high permeability and air-tightness make it an ideal air and water-resistive barrier membrane for energy-efficient construction. The product is watertight and protects the building enclosure from wind-driven rain. DELTA®-VENT S is very lightweight and tear-resistant. This membrane withstands the rigors of jobsites, as well as tough wind and weather.FeaturesWaterproof, resisting the passage of bulk water from wind-driven rain and snowHigh permeability – moisture accumulation within the structure is able to escape via diffusionMaximizes air tightness, making it ideal for energy-efficient constructionFabric layer on the lower side protects the WRB against damage (e.g. roughly sawn sheathing)Matte black; prevents blinding glare during installationLightweight, easily lined up and unrolledLarge roll size simplifies installation, while minimizing laps and maximizing productivity
