Product Description

DELTA®-STRATUS SA is engineered with two outer layers of high-strength polypropylene fabric, and a highly vapor-permeable, watertight polymeric middle layer. The fourth layer is an innovative acrylic UV-resistant coating that is proven to provide UV protection currently unheard of in the building industry.

Manufacturer Design Notes

DELTA®-STRATUS SA is a vapor-permeable WRB, allowing moisture within
the building enclosure to escape through the membrane via diffusion. Its
permeability and air-tightness make it an ideal air and water-resistive barrier
membrane for energy-efficient construction. The watertight membrane helps
protect the building enclosure from the damaging effects of moisture infiltration.
