Claim 13:
14. An assembly of an exterior building structure, comprising:
an inner sheathing member;
an exterior building material secured over said inner sheathing member and covering said inner sheathing member; and
a drainage-promoting wrap applied within the assembly between said inner sheathing member and said outer building material;
said wrap comprising an elongate, flexible strip of weather-resistive membrane having front and rear faces, a series of separate, spaced-apart, spacer elements bonded to said front face of said membrane and projecting therefrom to a predetermined height to provide drainage passageways between said wrap and said outer building material, and a layer of adhesive extending on said rear face of said membrane securing said wrap to said inner sheathing member;
wherein said layer of adhesive is a vapor permeable acrylic adhesive that extends continuously on said rear face of said membrane and completely covers said rear face;
wherein said layer of adhesive includes a scrim embedded therein for adding tensile and tear strength to the drainage promoting wrap; and
wherein said predetermined height of said spacer elements is equal to or greater than a thickness of said layer of adhesive.
