1. What is OSB Board?

OSB (Oriented Strand Board) is an engineered wood product made by compressing layers of wood strands with adhesives. It is known for its strength, durability, and affordability compared to plywood. OSB is widely used in construction for:

• Wall sheathing
• Roof decking
• Subflooring
• Furniture and packaging

Unlike plywood, which uses thin veneers, OSB is made from small wood strands arranged in cross-oriented layers, enhancing its structural stability.
