Abstract

A protective drainage wrap comprises a porous layer, a breathable solid layer portion and a plurality of fibers, filaments, tapes or yarn. The porous layer is adapted to allow water to pass therethrough. The breathable solid layer portion is adapted to allow water vapor to pass therethrough while preventing or inhibiting water from passing therethrough. The plurality of fibers, filaments, tapes or yarn is located between and attached to the porous layer and the breathable solid layer portion. The plurality of fibers, filaments, tapes or yarn forms a plurality of channels to assist in forming a drainage path for draining liquid water from the protective drainage wrap.

Claims

1. A protective drainage wrap comprising:

a porous layer being adapted to allow liquid water to pass therethrough;

a breathable solid layer portion being adapted to allow water vapor to pass therethrough while preventing or inhibiting liquid water from passing therethrough; and

a plurality of fibers, filaments, tapes or yarn being located between the porous layer and the breathable solid layer portion and being attached to the porous layer and the breathable solid layer portion, the plurality of fibers, filaments, tapes or yarn forming a plurality of channels to assist in forming a drainage path for draining liquid water from the protective drainage wrap.

2. The protective wrap of claim 1 wherein the porous layer is a building paper or housewrap.

3. The protective wrap of claim 1 wherein the porous layer is a non-woven porous material.

4. The protective wrap of claim 1 wherein the porous layer is felt.

5. The protective wrap of claim 1 wherein the breathable solid layer portion is a woven material with a breathable coating.

6. The protective wrap of claim 1 wherein the breathable solid layer portion is a spunbonded polymeric material.

7. The protective wrap of claim 6 wherein the polymeric spunbonded material is a polyolefin spunbonded material.

8. The protective wrap of claim 6 wherein the polyolefin spunbonded material includes polyester, nylon or the combination thereof.

9. The protective wrap of claim 1 wherein the breathable solid layer portion is a breathable film.

10. The protective wrap of claim 1 wherein the plurality of fibers, filaments, tapes or yarn comprises polypropylene, polyethylene or combinations thereof.

11. The protective wrap of claim 1 wherein the plurality of fibers, filaments, tapes or yarn is yarn.

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

providing a protective drainage wrap comprising a porous layer, a breathable solid layer portion and a plurality of fibers, filaments, tapes or yarn, the porous layer being adapted to allow liquid water to pass therethrough, the breathable solid layer portion being adapted to allow water vapor to pass therethrough while preventing or inhibiting liquid water from passing therethrough, the plurality of fibers, filaments, tapes or yarn being located between the porous layer and the breathable solid layer portion and being attached to the porous layer and the breathable solid layer portion, the plurality of fibers, filaments, tapes or yarn forming a plurality of channels to assist in forming a drainage path for draining liquid water from the protective drainage wrap;

providing at least one framing member; and

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

13. The method of claim 12 further including providing a sheathing, the sheathing being located between the protective wrap and the at least one framing members.

14. The method of claim 12 wherein the porous layer is a building paper or housewrap.

15. The method of claim 12 wherein the porous layer is a non-woven porous material.

16. The method of claim 12 wherein the porous layer is felt.

17. The method of claim 12 wherein the breathable solid layer portion is a woven material with a breathable coating.

18. The method of claim 12 wherein the breathable solid layer portion is a spunbonded polymeric material.

19. The method of claim 12 wherein the breathable solid layer portion is a breathable film.

20. The method of claim 12 further including the act of providing and installing stucco to the porous layer.

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

providing a protective drainage wrap comprising a porous layer, a breathable solid layer portion and a plurality of fibers, filaments, tapes or yarn, the porous layer being adapted to allow liquid water to pass therethrough, the breathable solid layer portion being adapted to allow water vapor to pass therethrough while preventing or inhibiting liquid water from passing therethrough, the plurality of fibers, filaments, tapes or yarn being located between the porous layer and the breathable solid layer portion and being attached to the porous layer and the breathable solid layer portion, the plurality of fibers, filaments, tapes or yarn forming a plurality of channels to assist in forming a drainage path for draining liquid water from the protective drainage wrap;

providing a sheathing; and

installing the protective drainage wrap over the sheathing.

22. The method of claim 21 wherein the porous layer is a building paper or housewrap.

23. The method of claim 21 wherein the porous layer is a non-woven porous material.

24. The method of claim 21 wherein the porous layer is felt.

25. The method of claim 21 wherein the breathable solid layer portion is a woven material with a breathable coating.
