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.

The invention claimed is: 1. An exterior wall or roof assembly of a building, comprising: an inner sheathing member; an exterior building material; and a drainage-promoting wrap applied within said assembly between said inner sheathing member and said exterior building material, said wrap comprising a weather-resistive membrane having a series of separate spaced-apart elongate polymeric filaments each separately bonded to a face of said membrane; said separate elongate filaments being sufficiently spaced-apart such that a portion of said face of said membrane is exposed between each adjacent pair of said separate spaced-apart elongate filaments; and each of said separate spaced-apart elongate polymeric filaments having a series of depressions formed therein that provide a series of drainage paths transversely across said filaments, each of said depressions being formed by a flattened section of said elongate filament, and each of said flattened sections being fused to said membrane to bond said filament to said membrane. 2. An assembly according to claim 1, wherein each of said filaments are of a common thickness that projects to a predetermined height from said face of said membrane, and wherein said series of depressions do not extend to said predetermined height. 3. An assembly according to claim 2, wherein said series of depressions are located at spaced intervals along a length of each filament. 4. An assembly according to claim 3, wherein said weather-resistive membrane is made of a non-polymeric material, and wherein said filaments are fused to said membrane via sonic bonding, adhesive bonding, or mechanical bonding techniques. 5. An assembly according to claim 3, wherein each of said filaments is a continuous extruded filament that extends in a longitudinal direction on said membrane and a substantially horizontal direction within said assembly. 6. An assembly according to claim 5, wherein said filaments extend substantially parallel to one another and substantially parallel to a longitudinal axis of said elongate membrane and do not intersect. 7. An assembly according to claim 5, wherein said weather-resistive membrane is made of a polymeric material that permits moisture vapor to pass therethrough, and wherein said filaments are thermally bonded to said membrane. 8. An assembly according to claim 7, wherein said exterior building material is selected from a group consisting of wood, brick, metal, steel, fiber cement, vinyl, stucco, asphalt, rubber, thermoplastic, and an exterior insulation finish system. 9. An exterior wall or roof assembly of a building, comprising an inner sheathing member, an exterior building material, and a drainage-promoting wrap extending between said inner sheathing member and said exterior building material, said wrap comprising: a weather-resistive membrane that blocks the penetration of water therethrough and that permits the passage of moisture vapor therethrough; and a series of separate elongate polymeric filaments separately bonded to a face of said membrane, each of said separate elongate polymeric filaments extending in a longitudinal direction on said membrane and a substantially horizontal direction within said assembly, and said separate elongate polymeric filaments being sufficiently spaced-apart such that a portion of said face of said membrane is exposed between each adjacent pair of said separate spaced-apart elongate filaments; each of said elongate filaments being of a common thickness that projects to a predetermined height from said face of said membrane and having a series of depressions formed therein that do not extend to said predetermined height and that provide a series of drainage paths transversely across said filaments; and said series of depressions being located at spaced intervals along a length of each of said elongate filaments and being formed by flattened sections of said elongate filaments, each of said flattened sections fusing said filament to said membrane to bond said filament to said membrane. 10. An assembly according to claim 9, wherein each of said separate elongate filaments is continuous and includes an alternating array of said depressions and full-size filament sections. 11. An assembly according to claim 10, wherein said separate elongate filaments do not intersect. 12. An assembly according to claim 11 wherein said weather-resistive membrane is made of a polymeric material, and wherein said flattened sections of said filaments are fused to said membrane by being thermally bonded to said membrane. 13. An assembly according to claim 12, wherein said exterior building material is selected from a group consisting of wood, brick, metal, steel, fiber cement, vinyl, stucco, asphalt, rubber, thermoplastic, and an exterior insulation finish system. 14. An assembly according to claim 12, wherein said filaments extend substantially parallel to one another. 15. An assembly according to claim 12, wherein said filaments extend substantially parallel to a longitudinal axis of said membrane. 16. An assembly according to claim 12, wherein said polymeric material of said weather-resistive membrane is selected from a group consisting of a woven thermoplastic material, a non-woven thermoplastic material, polypropylene, high density polyethylene, nylon, polyester, and polyolefin. 17. An assembly according to claim 16, wherein said polymeric filaments are made of a material selected from a group consisting of nylon, polypropylene, polyester, polyolefin, and polyethylene. 18. An assembly according to claim 17, wherein said face of said membrane within said assembly faces toward said exterior building material.
