What is the difference between Plywood and OSB?

Answer:
They are both engineered wood products, constructed using similar methods. The main difference is price. OSB (oriented-strand board) is generally cheaper and has a more uniform composition and appearance.

Even though they are both made of layers of smaller pieces of wood glued together, the small pieces that make up a sheet of plywood are still quite visible in the finished product, unllike OSB. OSB is also more commonly used nowadays in residential construction than plywood for cost reasons.
