Claims
- 1. A floor structure comprising:
a sub floor; a surface layer; and an insulative pad disposed between said sub floor and surface layer comprising binder and reinforcement fibers distributed substantially random in a first plane, said binder fibers being meltable at a predetermined temperature to couple the binding fibers to the reinforcement fibers.
- 2. The floor structure according to claim 1 wherein said surface material comprises wood.
- 3. The floor structure according to claim 1 wherein said surface material comprises ceramic.
- 4. The floor structure according to claim 1 wherein the binder fibers are selected from the group consisting of polyethylene, polyester, polypropylene, and mixtures thereof.
- 5. The floor structure according to claim 1 having a density of greater than about 10 pounds per cubic foot.
- 6. The floor structure according to claim 1 having a density of about 18.9 pounds per cubic foot.
- 7. The floor structure according to claim 6 being about {fraction (3/32)} inch thick.
- 8. The floor structure according to claim 1 having a compression resistance at a compression of 25% of the original thickness of greater than about 20 psi.
- 9. The floor structure according to claim 1 having a compression resistance at 50% of the original thickness of greater than about 180 psi.
- 10. A floor structure comprising:
a sub floor; a surface layer; an insulative pad having a density of greater than 10 pounds per cubic foot disposed between said sub floor and surface layer comprising binder and reinforcement fibers distributed substantially randomly, said binder fibers being meltable at a predetermined temperature to couple the binding fibers to the reinforcement fibers; and a vapor barrier disposed between the subfloor and the surface layer.
- 11. The floor structure according to claim 10 wherein said surface material comprises wood.
- 12. The floor structure according to claim 10 wherein said surface material comprises ceramic.
- 13. The floor structure according to claim 10 wherein the binder fibers are selected from the group consisting of polyethylene, polyester, polypropylene, and mixtures thereof.
- 14. The floor structure according to claim 10 having a density of greater than about 13.3 pounds per cubic foot.
- 15. The floor structure according to claim 10 having a density of about 18.9 pounds per cubic foot.
- 16. The floor structure according to claim 15 being about {fraction (3/32)} inch thick.
- 17. The floor structure according to claim 10 having a compression resistance at a compression of 25% of the original thickness of greater than about 20 psi.
- 18. The floor structure according to claim 10 having a compression resistance at 50% of the original thickness of greater than about 180 psi.
- 19. A floor structure comprising:
a sub floor; a surface layer; an insulative pad having a density of greater than 10 pounds per cubic foot disposed between said sub floor and surface layer comprising binder and reinforcement fibers distributed substantially randomly, said reinforcement fibers comprising fibers selected from the group nylon, acrylic, cotton, denim and mixtures thereof, said binder fibers being meltable at a predetermined temperature to couple the binding fibers to the reinforcement fibers, wherein the binder fibers are selected from the group consisting of polyethylene, polyester, polypropylene, and mixtures thereof; and a vapor barrier disposed between the subfloor and the surface layer.
- 20. The floor structure according to claim 10 wherein the vapor barrier is disposed adjacent the insulative pad.
