what is osb in construction？

OSB stands for Oriented Strand Board. It is a type of engineered wood panel made from strands of wood that are glued together in specific orientations to create a strong and durable panel.

OSB is often used as a substitute for plywood in construction applications such as flooring, walls, and roofs. It is also used as a sheathing material in exterior wall assemblies.

OSB is known for its strength, stability, and affordability compared to other building materials. It can be used in both residential and commercial construction projects and is often a preferred choice for its cost-effectiveness and ease of installation.
