Oriented Strand Board, or OSB, is an engineered wood product made from strands of wood that are oriented in specific directions and bonded together with adhesives. It is commonly used in construction for sheathing, flooring, and roofing due to its strength and durability. OSB is often considered a cost-effective alternative to plywood, as it can be produced from smaller trees and utilizes wood more efficiently. The manufacturing process of OSB involves layering strands of wood in different orientations, which enhances its structural integrity. This product is typically available in large sheets and is recognized for its versatility in various building applications. OSB is also treated to resist moisture, making it suitable for both indoor and outdoor use.
