Abstract: An engineered floor board or wood panel for the fabrication thereof is comprised of a thin top wood layer fabricated from a quality wood material. The top wood layer is glued to a core layer wood product having a grain orientation disposed transverse to the longitudinal axis of the top wood layer. A base wood layer is fabricated from oriented strand board (OSB) which is glued to the bottom of the core layer. The base wood layer is fabricated from a single sheet having wood particles and fibers oriented in at least two layers with at least a top layer having its wood particles and fibers generally oriented along the longitudinal axis of the top wood layer and transverse to use core layer to substantially prevent displacement and deformation of the core layer caused by expansion and retraction thereof and thereby preventing deformations in the top wood layer.
