Oriented strand board (OSB) is most frequently used in which application?

Oriented strand board (OSB) is primarily recognized for its structural applications in construction, particularly in roof, floor, and exterior wall sheathing. This engineered wood product is made from strands of wood that are bonded together with adhesives, creating a strong and versatile material suitable for these applications.

The use of OSB for roof, floor, and exterior wall sheathing is due to its durability, strength-to-weight ratio, and cost-effectiveness compared to other building materials. It is commonly utilized to provide a sturdy base for roofing materials, support flooring systems, and form part of the wall assembly in buildings.

While OSB can be employed in various applications, including certain interior uses, the primary and most frequent usage remains for structural sheathing, making it an essential material in the construction industry.
