Abstract

A protective drainage wrap comprises a polymeric spunbonded portion being adapted to allow water vapor to flow therethrough and a plurality of fibers, filaments, tapes or yarn being attached to the polymeric spunbonded portion. The plurality of fibers, filaments, tapes or yarn forms a plurality of channels to assist in forming a drainage path for draining liquid moisture from the protective drainage wrap.

Claims

1-6. -6. (canceled)

7. A method of using a protective wrap in a building, the method comprising the acts of:

providing a protective wrap including a polymeric spunbonded portion and a plurality of fibers, filaments, tapes or yarn, the polymeric spunbonded portion being adapted to allow water vapor to flow therethrough, the plurality of fibers, filaments, tapes or yarn being attached to the polymeric spunbonded portion and forming a plurality of channels to assist in facilitating a drainage path for draining liquid moisture from the protective drainage wrap;

providing at least one framing member; and

installing the protective wrap over at least one of the framing members.

8. The method of claim 7 further comprising providing an exterior covering selected from siding, brick, masonry, stucco or concrete veneer and installing the exterior covering over the protective wrap.

9. The method of claim 7 wherein the at least one framing member is plywood or oriented-strand board.

10. The method of claim 7 further including providing a sheathing, the sheathing being located between the protective wrap and the at least one framing member.

17. The method of claim 7 wherein the polymeric spunbonded portion is a polyolefin spunbonded portion.

18. The method of claim 17 wherein the polyolefin spunbonded portion is polyethylene, polypropylene or the combination thereof.

19. The method of claim 7 wherein the polymeric spunbonded portion includes polyester, nylon or the combination thereof.

20. The method of claim 7 wherein the plurality of fibers, filaments, tapes or yarn comprises polypropylene, polyethylene or combinations thereof.

21. The method of claim 7 wherein the plurality of fibers, filaments, tapes or yarn is fibers.

11. A method of using a protective wrap in a building, the method comprising the acts of:

providing a protective wrap including a polymeric spunbonded portion and a plurality of fibers, filaments, tapes or yarn, the polymeric spunbonded portion being adapted to allow water vapor to flow therethrough, the plurality of fibers, filaments, tapes or yarn being attached to the polymeric spunbonded portion and forming a plurality of channels to assist in facilitating a drainage path for draining liquid moisture from the protective drainage wrap;

providing a sheathing; and

installing the protective wrap over the sheathing.

12. The method of claim 11 further comprising providing an exterior covering selected from siding, brick, masonry, stucco or concrete veneer and installing the exterior covering over the protective wrap.

22. The method of claim 11 wherein the polymeric spunbonded portion is a polyolefin spunbonded portion.

23. The method of claim 22 wherein the polyolefin spunbonded portion is polyethylene, polypropylene or the combination thereof.

24. The method of claim 11 wherein the polymeric spunbonded portion includes polyester, nylon or the combination thereof.

25. The method of claim 11 wherein the plurality of fibers, filaments, tapes or yarn comprises polypropylene, polyethylene or combinations thereof.

26. The method of claim 11 wherein the plurality of fibers, filaments, tapes or yarn is fibers.

27. The method of claim 11 wherein the plurality of fibers, filaments, tapes or yarn is yarn.

13-16. -16. (canceled)
