An underlayment assembly comprising an underlayment with an upper and a lower surface, an adhesive layer disposed on the upper surface, and a release [layer] fastener disposed on the adhesive layer, optionally with an adhesive layer on the lower surface of the underlayment, is disclosed. One or more
An underlayment assembly comprising an underlayment with an upper and a lower surface, an adhesive layer disposed on the upper surface, and a release [layer] fastener disposed on the adhesive layer, optionally with an adhesive layer on the lower surface of the underlayment, is disclosed. One or more performance enhancing layers, such as foam and solid layers, can be disposed between the underlayment and the adhesive layer to modify and/or enhance various properties of the underlayment. A primary fastener comprising part of a hook and loop fastener assembly can be attached to the upper surface of the underlayment. Mechanical fasteners, such as staples, penetrate the underlayment assembly and engage a structural support member to attach the underlayment assembly thereto. Methods for installing a surface covering over a structural support member using the underlayment assembly are also disclosed.

The barrier membrane according to claim 1, wherein the aliphatic thermoplastic urethane of said first layer includes at least one polyester based urethane. 6. The barrier membrane according to claim 1, wherein said second layer of thermoplastic urethane is selected from the group consisting of polyester, polyether, polycaprolactone, polyoxypropylene and polycarbonate macroglycol based materials and mixtures thereof. 7. The barrier membrane according to claim 1, wherein said first layer including a blend of aliphatic thermoplastic urethane and a copolymer of ethylene and vinyl alcohol has an average thickness of between about 0.5 mils to about 10 mils and said second layer including thermoplastic urethane has an average thickness of between about 5 mils to about 100 mils. 8. The barrier membrane according to claim 1, wherein said second layer also includes an aromatic urethane. 9. The barrier membrane according to claim 1, wherein said first layer includes: (a) 50 wt. % to about 97 wt. % of at least one ethylene and vinyl alcohol copolymer; (b) 3 wt. % to about 50 wt. % of at least one aliphatic thermoplastic urethane; and (c) up to about 3.0 wt. % of one or more aromatic urethanes; wherein the total constituency of said first layer is equal to 100.0 wt. %. 10. The barrier membrane according to claim 1, further comprising a third layer including a thermoplastic urethane. 11. The barrier membrane according to claim 2, wherein said first layer including a blend of at least one aliphatic thermoplastic urethane and a copolymer of ethylene and vinyl alcohol has an average thickness of between about 0.5 mils to about 10 mils and said second and third layers including thermoplastic urethanes have an average thickness of between about 5 mils to about 100 mils. 12. A barrier membrane having an improved resistance to undesired gas permeation, comprising: a first, barrier layer including a combination of at least one aliphatic thermoplastic urethane and one or more copolymers of ethylene and vinyl alcohol; a second, outer layer induding a thermoplastic urethane; and a third, inner layer including a thermoplastic urethane, wherein said second and third layers sandwich the first layer; wherein hydrogen bonding occurs along a segment of the membrane between the first layer and at least one of said second or third layers, and further wherein said barrier membrane is sealed and is inflated with a gas toward which said membrane has a gas transmission rate value of about 10.0 cc/m2×atm×dayor less and wherein said first layer includes up to about 50 wt. % of aliphatic thermoplastic urethane. 13. The barrier membrane according to claim 12, wherein said first layer includes between about 1 wt. % to about 30 wt. % of aliphatic thermoplastic urethane. 14. The barrier membrane according to claim 13, wherein said first layer includes between about 5 wt. % to about 25 wt. % of aliphatic thermoplastic urethane. 15. The barrier membrane according to claim 12, wherein said copolymer of ethylene and vinyl alcohol is selected from the group consisting of copolymers including an ethylene content of between about 25 mol. % to about 48 mol. %. 16. The barrier membrane according to claim 12, wherein the aliphatic thermoplastic urethane of said first layer includes at least one polyester based urethane. 17. The barrier membrane according to claim 12, wherein the thermoplastic urethane of at least one of said second or third layers is selected from the group consisting of polyester, polyether, polycaprolactone, polyoxypropylene and polycarbonate macroglycol based materials and mixtures thereof. 18. The barrier membrane according to claim 12 wherein said first layer has an average thickness of between about 0.5 mils to about 10 mils and said second and t
