In roofing terminology, what does the acronym OSB stand for?

The term OSB stands for Oriented Strand Board, which is a type of engineered wood product made from strands or flakes of wood that are oriented and bonded together with adhesives under heat and pressure. OSB is widely used in construction, particularly for sheathing in walls, roofs, and floors, due to its strength, durability, and cost-effectiveness. Its manufacturing process allows for the utilization of smaller trees and wood scraps, making it a more sustainable choice compared to traditional plywood. Recognizing the significance of OSB in roofing terminology is essential for home inspectors, as it is commonly used as a structural component in modern roofing systems. Understanding the properties and applications of OSB can help inspectors evaluate the quality and safety of roofing installations.
