No, an OSB (Oriented Strand Board) sheet is not the same as fiberboard. OSB is made from strands of wood that are oriented and pressed together, providing strength and structural integrity. In contrast, fiberboard is made from wood fibers that are bonded together, often resulting in a denser and more uniform material, typically used for insulation or as a substrate. Each type of board has distinct properties and applications in construction and manufacturing.
