An oriented strand board product is provided. The board is comprised of a baseboard having three wood strand layers, the wood strands being oriented in space with respect to a board-forming machine such that a core layer is comprised of wood strands oriented generally in a random or cross-machine direction and each adjacent layer is comprised of coarse and fine wood strands oriented generally in the machine direction and wherein the wood strands comprising each adjacent layer are formed with the coarsest strands located nearest the core layer and the finest strands are located nearest the outer surfaces of each outer board layer. The OSB board product is clad with a dry felted wood fiber overlay on one planar surface of the baseboard.
