1. A building wrap membrane comprising a flexible sheet of spun bonded vapor permeable polypropylene base sheet member, a drainage matrix is secured to a front surface of said base sheet member, said drainage matrix being constructed of individual thermoplastic threads randomly laid down and secured together by heat bonding; said thermoplastic threads being formed into parallel spaced thread rows forming channels between each spaced row, a coating of permeable pressure sensitive adhesive covers a back surface of said base sheet member and a film release sheet covers said pressure sensitive adhesive. 2. A building wrap membrane of claim 1, wherein said thermoplastic threads are nylon threads. 3. A building wrap membrane of claim 1, wherein said thermoplastic threads are polypropylene threads. 4. A building wrap membrane of claim 1, wherein each thread row has a height of about 3 mm nominal plus or minus 1 mm in height. 5. A building wrap membrane of claim 1, wherein each thread row has a height of about 7 mm nominal plus or minus 1 mm in height. 6. A building wrap membrane of claim 1, wherein each thread row height is about 11 mm nominal plus or minus 1 mm in height. 7. A building wrap membrane of claim 1, wherein said release sheet is a clear polyester film silicon treated on one side having a thickness ranging from about 1 mil to about 2 mils. 8. A building wrap membrane of claim 1, wherein said coating of permeable pressure sensitive adhesive has entrained interconnected air formed pores. 9. A building wrap membrane of claim 1, wherein said pressure sensitive adhesive comprises a water based copolymer with a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with at least one solvent-free surfactant and is emulsified to produce air bubbles which form pores within said copolymer adhesive when the copolymer pressure sensitive adhesive is cured, said pores being uniformly distributed and interconnected throughout said pressure sensitive adhesive to form a water resistive water vapor flow path through the pressure sensitive adhesive. 10. A building wrap membrane of claim 1, wherein said pressure sensitive adhesive has a vapor permeability ranging from about 30 Perms to about 50 Perms. 11. A building wrap membrane of claim 1, wherein said drainage matrix secured to said sheet member on the said front surface of said sheet member by spot welding said drainage matrix to said sheet member and said drainage matrix is comprised of individual thermoplastic threads randomly laid down to form a net and secured together by heat bonding; said thermoplastic threads being formed into spaced rows ranging from about ½ inch to about 1 inch in width with a substantially uniform height and a uniform channel. 12. A water vapor permeable air and moisture barrier rain drainage sheet configured in sheet form that can be applied to a building wall structure comprising a sheet of spun bonded polypropylene sheet member with integral permeable pressure sensitive adhesive coated over the rear surface of said sheet member, a removable release sheet is mounted on said coated permeable pressure sensitive adhesive covering said permeable pressure sensitive adhesive, a drainage matrix is secured to said sheet member on the front surface of said sheet member, said drainage matrix being comprised of individual thermoplastic threads randomly laid down to form a fibrous mat and secured together by heat bonding; said drainage matrix being secured to said surface of said sheet member by spot welding, forming a plurality of spaced parallel thread rows ranging from about ½ inch to about 1 inch in width and defining a channel there between. 13. A building wrap membrane of claim 12, wherein said thermoplastic threads are composed of nylon threads. 14. A building wrap membrane of claim 12, wherein said thermoplastic threads are composed of polypropylene threads. 15. A building wrap membrane of claim 12, wherein each thread row has a height of about 3 mm nominal plus or minus 1 mm in height. 16. A building wrap membrane of claim 12, wherein each thread row has a height of about 7 mm nominal plus or minus 1 mm in height. 17. A building wrap membrane of claim 12, wherein each thread row height is about 11 mm nominal plus or minus 1 mm in height. 18. A building wrap membrane of claim 12, wherein said release sheet is a clear polyester film having a thickness ranging from about 1 mil to about 2 mils and silicon treated. 19. A building wrap membrane of claim 12, wherein said pressure sensitive adhesive having a vapor permeability of at least 40 Perms. 20. A building wrap membrane of claim 12, wherein said pressure sensitive adhesive having a vapor permeability ranging from about 30 Perms to about 50 Perms. 21. A building wrap membrane of claim 12, wherein said pressure sensitive adhesive comprises a water based copolymer with a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with at least one solvent-free surfactant and is emulsified to produce air bubbles which form pores within said copolymer adhesive when the copolymer pressure sensitive adhesive is cured, said pores being uniformly distributed and interconnected throughout said pressure sensitive adhesive to form a water resistive water vapor flow path through the pressure sensitive adhesive. 22. A building wrap membrane of claim 12, wherein said pressure sensitive adhesive has a vapor permeability ranging from about 30 Perms to about 50 Perms. 23. A building wrap membrane comprising a flexible sheet of spun bonded vapor permeable polypropylene base planar member, a three dimensional drainage matrix secured by heat bonding to a front surface of said base planar member, said drainage matrix being constructed of individual convoluted thermoplastic threads randomly laid down on a front surface of said base sheet member and secured together by heat bonding; said thermoplastic threads being formed into parallel spaced thread rows forming channels between each spaced row, each row having a height ranging from between about 3 mm to about 11 mm, a coating of water soluble solvent free permeable pressure sensitive acrylic based adhesive covers a back surface of said base planar member, said building wrap membrane having a vapor permeability ranging from about 30 Perms to about 50 Perms, and a plastic film release sheet mounted over said pressure sensitive adhesive.
