Which is better, OSB or plywood? It depends on who you ask, where they build, what they want to pay, and numerous other variables. Some builders respond to exaggerated fears by refusing to use OSB, while others love the stuff and use it every chance they get. One thing is certain, however – OSB is now produced more than plywood, at least in North America. Most opinions as to which material is superior are based on heresay and experience, often from biased sources attempting to sell one material. Thankfully, however, a formal study was conducted by Georgia-Pacific, a manufacturer of both materials, which clearly preferred one material to the other. The results of that study, as well as other interesting pieces of information, are incorporated in our new article on the pros and cons of OSB and plywood.
