ABSTRACT:
A hardwood, free floating floor system has upper and lower subfloors of wooden panels with criss-cross kerf patterns formed in either their top or bottom surfaces, a plurality of elongated floorboards disposed above the upper subfloor, the floorboards having transverse kerfs cut in their bottom surfaces, and a plurality of uniformly spaced pads supporting the lower subfloor above a base. The combination of the subfloor kerf patterns, the floorboard kerfs, and the compressible, deflectable pads provides a free floating hardwood floor system which meets the difficult standards established by the Otto Graf Institut of West Germany for assessing a floor's ability to reduce injury and to provide highly consistent performance characteristics.
