OSBs

OSB, or Oriented Strand Board, is a type of engineered wood panel that is manufactured by layering wood strands in specific orientations. These strands are then combined with binders and pressed together under heat and pressure. The manufacturing process typically involves cutting wood into long, flat strands, which are then mixed with adhesives and formed into mats. The direction of the strands in each layer is alternated, with outer layers typically oriented parallel to the panel's length and inner layers oriented perpendicular. This cross-directional layering contributes to the panel's structural strength and stability.

OSB is commonly used as a building material, particularly in the construction of walls, floors, and roofs. Its strength, rigidity, and cost-effectiveness make it a popular alternative to plywood. It is often used as sheathing, providing structural support and a surface for applying siding or roofing materials. OSB panels are available in various thicknesses and grades depending on their intended application. The specific type of wood used can vary, but common species include pine, spruce, and poplar. While it offers good structural performance, OSB is susceptible to moisture damage and requires proper sealing and protection in exposed applications.
