Abstract
A ventilated quarter round molding or shoe molding can be used, in combination with a water impervious underlayment to dissipate water vapor which is often generated from subfloors. Such water vapor can damage certain flooring, and the invention allows for the installation of devices to limit or eliminate such damage without significant cost.
Claims14
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.
