A free floating hard wood floor system has upper and lower subfloors sandwiched to provide a monolithic panel system which supports the floorboards above with optimum rigidity and integrity at a reduced cost. Flat nail clinching strips are located between the sandwiched upper and lower subfloors. The floorboards disposed above the upper subfloor are secured thereto by a plurality of clinching nails extending through the floorboards, the upper subfloor and into the upper subfloor after deflecting on the flat clinching strips.

A finger jointed floorboard or laminatable floorboard section of two connected shorter pieces includes a relatively thick upper wear region which may be sanded without exposing the fingers forming the connection, regardless of whether or not the pieces are connected in the same longitudinal and transverse horizontal planes. The structure and orientation of this finger joint allows flooring manufacturers to maximize the yield of typically solid, good quality floorboard material and to reduce installation costs, without adversely affecting the aesthetic quality of the installed floor. In one embodiment, a finger jointed board with a central finger joint is sawed in a horizontal plane through the joint to produce two identical, laminatable floorboard sections. With a thicker starting board having two separate, spaced finger joint connections, sawing along a horizontal midplane produces two identical intermediate boards, each with a centrally located finger joint. Each intermediate board is then sawed through the finger joint connection to produce a total of four laminatable floorboard sections.

A free floating hard wood floor system has upper and lower subfloors sandwiched to provide a monolithic panel system which supports the floorboards with optimum rigidity and integrity at a reduced cost. The upper subfloor has grooves milled in the bottom surface with flat clinching strips received within the grooves. The floorboards are disposed above the upper subfloor and secured thereto by a plurality of clinching nails extending through the florboards, the upper subfloor and into the upper subfloor after deflecting on said clinching strips.
