The present invention provides a water management building wrap that may be useable between a frame structure of a building and an exterior building covering. In at least one embodiment, the building wrap comprises a permeable membrane and an extruded polymeric drainage structure secured to the second side of the membrane. In at least one embodiment, the drainage structure includes a plurality of generally vertical members having a first thickness and forming boundaries for generally vertical water drainage channels, and a plurality of generally horizontal members attached to the generally vertical members and having a second thickness less than the first thickness and forming integral joints at intersections of the generally vertical members and the generally horizontal members that provide dimensional stability to maintain the orientation of the generally vertical members and form stable vertical water drainage channels.

What is claimed is: 1. A water management building wrap comprising: a first membrane having a first side and a second side; an extruded polymeric netting structure secured to one of the sides of the membrane, the netting structure including a plurality of generally vertical members having a first average thickness and spaced apart from each other such that adjacent pairs of the generally vertical members form boundaries for a generally vertical water drainage channel, the netting structure further including a plurality of generally horizontal members extending between and attached to the generally vertical members and having a second average thickness less than the first thickness, the netting structure having integral joints at intersections of the generally vertical members and the generally horizontal members, the netting structure having a core of a first material and an outer layer of a second material surrounding at least a portion of the core; and a second non-permeable membrane disposed over a side of the netting opposite the first membrane. 2. The building wrap of claim 1, wherein the melting point of the outer layer is lower than the melting point of the core. 3. The building wrap of claim 2, wherein the membrane is permeable. 4. The building wrap of claim 3, wherein the netting is secured to the permeable membrane by being laminated to the permeable membrane. 5. The building wrap of claim 4, wherein the outer layer of the netting structure is melted and bonded to the permeable membrane to cause the netting to be laminated to the permeable membrane. 6. The building wrap of claim 3, wherein the permeable membrane has a thickness of 1 to 75 mils. 7. The building wrap of claim 2, wherein the membrane is water resistant. 8. A netting disposable between a first, permeable, membrane and a second, non-permeable, membrane to provide a water management building wrap having vertical water drainage channels between the membranes, the netting comprising: an extruded polymeric netting structure securable to one side of the first membrane and between the first and second membranes, the netting structure including a plurality of generally vertical members spaced apart from each other such that adjacent pairs of the generally vertical members form boundaries for a generally vertical water drainage channel, the netting structure further including a plurality of generally horizontal members extending between and attached to the generally vertical members, the netting structure having integral joints at intersections of the generally vertical members and the generally horizontal members, the joints providing dimensional stability to maintain the orientation of the generally vertical members and form stable vertical water drainage channels, the netting structure having a core of a first material and an outer layer of a second material surrounding at least a portion of the core. 9. A method of forming a water management building wrap for use between a sheathing of a building and an exterior building covering, the method comprising: disposing a permeable membrane over at least a portion of the sheathing, the membrane having a first side and a second side, the first side, when the membrane is disposed on the sheathing, facing the sheathing; and disposing an extruded polymeric netting structure over the second side of the membrane, the netting structure including a plurality of generally vertical members having a first thickness and spaced apart from each other such that adjacent pairs of the generally vertical members form boundaries for a generally vertical water drainage channel, the netting structure further including a plurality of generally horizontal members extending between and attached to the generally vertical members and having a second thickness less than the first thickness, the members having a core of a first material and an outer layer of a second material surrounding at least a portion of the core, the netting structure having integral joints at intersections of the generally vertical members and the generally horizontal members, the joints providing dimensional stability to maintain the orientation of the generally vertical members and form stable vertical water drainage channels; and disposing a second non-permeable membrane over a side of the netting structure opposite the permeable membrane. 10. The method of claim 9 further comprising, heating the netting structure to melt the outer layer, thereby adhering the netting structure to the permeable membrane. 11. A building wrap for managing water drainage from an exterior wall of a building, the wrap being for use between a frame and an exterior covering of the building, the building wrap comprising: a first membrane formed of a sheet of permeable material and being disposable over the frame; a netting formed of a unitary polymeric extrusion, the netting disposed over the first membrane, the netting having a series of generally vertical members and a series of generally horizontal members having integral joints at intersections between the generally vertical members and the generally horizontal members, the netting having an array of water drainage channels, wherein the netting includes a core of a first material and an outer layer of a second material surrounding at least a portion of the core; and a second non-permeable membrane disposed over a side of the netting opposite the first membrane. 12. The building wrap of claim 11, in the melting point of the outer layer is lower than the melting point of the core. 13. The building wrap of claim 12, wherein the netting is laminated to the first membrane. 14. The building wrap of claim 12, wherein the netting is laminated to the first membrane by melting the outer layer of the netting. 15. The building wrap of claim 11, wherein the first membrane has a thickness of 1 to 75 mils.
