We claim: 1. An assembled molding system comprising: a molding comprising an outer decorative surface and a rear surface, the rear surface defining a plurality of air and water vapor conveying ducts therein, and an underlayment providing air and water vapor communication with the plurality of the air and water vapor conveying ducts of the molding, where the underlayment is provided between a subfloor and at least one flooring element positioned over said underlayment, and the molding is placed above the at least one floor element with its air and water vapor conveying ducts in air and water vapor communication with the air and water vapor conveying ducts of the underlayment; wherein said molding is selected from the group consisting of a wall base molding, a quarter round molding and a shoe molding, wherein the molding is attached to a structure by means of a clip, wherein said structure is selected from the group consisting of a wall and a wall base molding. 2. An assembled molding system comprising: a molding comprising an outer decorative surface and a rear surface, the rear surface defining a plurality of air and water vapor conveying ducts therein, and an underlayment providing air and water vapor communication with the plurality of the air and water vapor conveying ducts of the molding, where the underlayment is provided between a subfloor and at least one flooring element positioned over said underlayment, and the molding is placed above the at least one floor element with its air and water vapor conveying ducts in air and water vapor communication with the air and water vapor conveying ducts of the underlayment; wherein the molding is a quarter round molding and is positioned adjacent a wall or wall base such that the ducts permit ventilation of water vapor from below the molding to escape. 3. The assembled molding system of claim 1, wherein the underlayment comprises a barrier layer having channels defined therein. 4. The assembled molding system of claim 3, wherein the channels are defined by bosses. 5. The assembled molding system of claim 1, further comprising a spacing material positioned in the ducts. 6. The assembled molding system of claim 5, wherein the spacing material comprises physical spaces therein or absorbs water vapor. 7. The assembled molding system of claim 1, wherein the ducts are coated with a material which hinders water absorption. 8. The assembled molding system of claim 1, further comprising a longitudinal depression in fluid communication with a plurality of the ducts. 9. The assembled molding system of claim 1, wherein the outer decorative surface is at least one selected from the group consisting of laminate, liquid coating, wood veneer, foil, polyesters, paints, vinyls, liquid coatings and metals. 10. An assembly comprising: a floor, positioned above a subfloor; a wall, positioned adjacent the floor; and the assembled molding system of claim 1, connected to at least one of the floor and the wall. 11. The assembly of claim 10, wherein the assembly further comprises a barrier layer positioned between the subfloor and the floor. 12. The assembly of claim 11, wherein the barrier layer has channels therein, and the channels are in fluid communication with the ducts. 13. The assembly of claim 10, wherein the outer decorative surface of the molding is the same as a décor of at least one of the floor and the wall. 14. A structure comprising the assembly of claim 10, wherein the structure is selected from the group consisting of a home, shopping mall, restaurant, retail establishment, warehouse and office building.
