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.
An oriented strand board-fiberboard composite structure that does not delaminate upon weathering comprising a multilayer oriented strand board core including a plurality of wood strand layers, including a first layer formed from wood strands oriented generally in a random or cross-machine direction and a second layer bonded to said first layer, and formed from wood strands oriented in a direction generally perpendicular to said first layer;
An oriented strand board-fiberboard composite structure comprising a plurality of layers of oriented strand board material forming a core, each layer loosely formed separately and disposed one above the other, wherein a top layer is a layer of oriented strand board material having wood strands of varying dimensions, and an overlay secured to the oriented strand board core such that the overlay does not delaminate upon weathering, said overlay formed into a handleable dry-felted fiberboard mat including entangled, fibrillated wood fibers and, thereafter, hot pressed to consolidate the fiberboard mat simultaneously with hot pressing the oriented strand board core to bond the core and the fiberboard mat together, said fiberboard overlay having a planar outer surface.
An oriented strand board-fiberboard composite structure that does not delaminate upon weathering comprising a multilayer oriented strand board core including a plurality of wood strand layers, including a layer formed from wood strands oriented generally in a random or cross-machine direction and another layer bonded thereto, and formed from wood strands oriented in a direction generally perpendicular to said first layer;
An oriented strand board-fiberboard composite structure that does not delaminate upon weathering comprising a multilayer oriented strand board core including three wood strand layers, including a second layer formed from wood strands oriented generally in a random or cross-machine direction and first and third adjacent layers formed from wood strands oriented in a direction generally perpendicular to said second layer;
