ABSTRACT:
A hardwood floor system has upper and lower subfloors of wooden panels, a plurality of elongated floorboards disposed above the upper subfloor and a plurality of uniformly spaced compressible, deflectable pads supporting the lower subfloor above a base, with at least one kerfed surface in the group of surfaces including the floorboard bottom surface, the upper subfloor surfaces, and the lower subfloor surfaces. In a free-floating embodiment of the invention, each of the pads includes a glide tip that is slidable with respect to the base. This combination of kerfs and compressible, deflectable pads provides a hardwood floor system that substantially complies with the performance characteristics established by the Otto Graf Institut of West Germany for evaluating hardwood floor systems, but in a more economical manner than another embodiment of the invention described in the parent application.
