Claim 17:
18. A drainage-promoting wrap for a building structure, 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;
a layer of adhesive extending on said rear face of said membrane;
a scrim for adding tensile and tear strength to the drainage promoting wrap is embedded within said layer of adhesive; and
a release liner covering said layer of adhesive;
wherein said layer of adhesive extends continuously on said rear face of said membrane and is a vapor permeable acrylic adhesive;
wherein said membrane having said spacer elements, said layer of adhesive, said scrim embedded within said layer of adhesive, and said release liner is storable in a spiral roll; and
wherein said membrane is water impermeable in a direction through the membrane from said front face to said rear face and is water vapor permeable in a direction through the membrane from said rear face to said front face.
