Although this book covers the details of using OSB, we've found over the years that there are a set of commonly asked questions by our customers about specific uses of OSB. They range from the simple to the unusual. In this chapter, we'll provide answers to the most commonly asked questions. Furthermore, we've picked out a few questions that might be uncommon, but that demonstrate just how flexible OSB is in practice. The questions are broken down into different categories, to help you find the answers. Some questions cross these categorical boundaries. Where appropriate, we've given credit to the folks who answered the original questions.
