DELTA®-Vent S / Plus
Brand: DeltaThe 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.
Features- Waterproof, resisting the passage of bulk water from wind-driven rain and snow
 - High permeability – moisture accumulation within the structure is able to escape via diffusion
 - Maximizes air tightness, making it ideal for energy-efficient construction
 - Fabric layer on the lower side protects the WRB against damage (e.g. roughly sawn sheathing)
 - Matte black; prevents blinding glare during installation
 - Lightweight, easily lined up and unrolled
 - Large roll size simplifies installation, while minimizing laps and maximizing productivity

DELTA®-VENT S is installed outboard of the sheathing prior to the application of the final cladding system. Use DELTA®-LFS 100% silicone for liquid flashing and sealant applications. 
Do not use sealants, flashings, products or chemicals that contain surfactants on DELTA® water-resistive and air barrier membranes because they can adversely affect the water hold-out properties of any PP spunbond-based water-resistive barrier. 
Such products may include asphaltic materials, various chemicals, acid-based silicones, cleaning compounds, and certain formulations of liquid flashings, e.g. specific STP-based materials. Always confirm compatibility with the manufacturer’s published technical data sheets and with the manufacturer’s technical department. DELTA®Accessories complement the WRB / Air Barrier installation. DELTA®-VENT S is also available in the PLUS version with a self-adhesive edge.
