Abstract
A water-shedding flashing for use in a cavity wall is disclosed. The flashing includes a modified textured surface with a super-hydrophobic layer that achieves water contact angles between 120 degrees and 165 degrees. Water and water vapor do not adhere to the flashing, causing the water to bead and fall from the flashing. Such combination results in a flashing that works in conjunction with the exterior channels in the outer wythe to produce an efficient water removal and ventilation system within the cavity wall structure. A labor-saving peel-and-stick adhesive with release sheet for installation on the inner wythe utilizes clear, nondrooling adhesives.
