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 wood based laminate;
- an insulator layer disposed adjacent to wood based laminate, the insulator layer consisting of an insulative pad and a co-extruded polyethylene vapor barrier bonded to the insulative pad, the insulative pad having a density of greater than about 10.0 pounds per cubic foot, said insulative pad consisting of a fibrous web layer comprising reinforcement fibers distributed substantially randomly, said reinforcement fibers being interlocked, wherein after the insulative pad material is compressed to 75% of its original thickness during a compression set test, the insulative pad material is then capable of returning to more than 80% of its original thickness and has a compression resistance at a compression of 25% of the original thickness of greater than about 20 psi.
A floor structure consisting of:
- a wood based laminate;
- an insulator layer disposed adjacent to wood based laminate and consisting of a co-extruded polyethylene vapor barrier coupled to an insulative pad, said insulative pad consisting of a fibrous web distributed substantially randomly, said reinforcement fibers being interlocked, wherein after the insulative pad material is compressed to 75% of its original thickness during a compression set test, the material is then capable of returning to more than 80% of its original thickness.
A floor structure consisting of:
- a wood based laminate;
- an insulator layer disposed adjacent to wood based laminate, said insulative layer consisting of a fibrous web layer and a means for preventing the travel of water vapor through the insulative pad that is fixably coupled to the insulative pad, wherein said fibrous web layer comprises reinforcement fibers selected from the group containing polyethylene, polyester, polypropylene and mixtures thereof, distributed substantially randomly, said reinforcement fibers being interlocked, wherein after the insulative pad material is compressed to 75% of its original thickness during a compression set test, the material is then capable of returning to more than 80% of its original thickness.
