ABSTRACT:
A drainage-promoting wrap includes an elongate web of a weather-resistive membrane and a series of separate, laterally spaced-apart, elongate filament spacers bonded to a face of the membrane. The filaments are preferably extruded polymeric filaments and have depressions formed therein providing transverse drainage paths across the filaments. Preferably, the filaments extend substantially parallel to each other and to a longitudinal axis of the elongate membrane. In addition, preferably the membrane is made of a polymeric material so that the filaments are thermally bonded to the face of the membrane. Wall and roof assemblies utilizing the wrap and methods of making the wrap are provided.
