Abstract:
A smooth-sided, multi-layer, integral, composite engineered panel having outer surfaces, which comprises:a plurality of layers comprising lignocellulosic strands or wafers having outer surfaces, said plurality of layers being bonded together by an adhesive material; at least one layer of smaller particles of lignocellulosic material bonded together by an adhesive material, said layer of smaller particles of lignocellulosic material joined to at least one of the outer surfaces of the plurality of layers, the average size of said lignocellulosic smaller particles being less than the average size of the lignocellulosic strands or wafers in the plurality of layers; and at least one sheet of paper, each said paper sheet being joined to said layer of smaller particles of lignocellulosic material during the formation of the engineered panel, at least one of said surfaces of said engineered panel having a substantially smooth outer surface which is maintained in said substantially smooth state when exposed to water or high humidity conditions, each said substantially smooth outer surface of said engineered panel being substantially devoid of telegraphing.
