Abstract
A flooring material having a textile pad substructure with a density of greater than 10 pounds per cubic foot is provided. The textile pad has reinforcement and binding fibers. The binding fibers are thermoplastic and are used to bind the reinforcement fibers together. The pad is created by heating and compressing a fibrous textile batt so that it has a density of greater than 13 pounds per cubic foot.
Claims16
A floor structure consisting of:
- a sub floor;
- a single wood layer;
- and
- an insulative pad disposed between said sub floor and said single wood layer, said insulative pad consisting of a fibrous web layer where one surface of said web layer is coated with an adhesive and wherein said web layer comprises binder and reinforcement fibers distributed substantially random in a first plane, said binder fibers being meltable at a predetermined temperature to couple the binder fibers to the reinforcement fibers;
- and
- a single layer polyethylene vapor barrier, fixably coupled to the insulative pad.
