We use a lot of 3-letter acronyms in the sunroom industry, but one you might hear bandied about the most is OSB, which stands for Oriented Strand Board. Since we use this material so often, we figured we’d give you the 101 on OSB and break it down to the basics: what it is, how we use it, and why it’s useful. So strap in for your OSB orientation.At LivingSpace, OSB is one of the main components we use to make our Eco Green panels. These panels are incredibly versatile - we use them to build roofing, decking, knee wall panels, and more. Eco Green panels are a compound building element, with a thick layer of dense foam sandwiched between two pieces of OSB, for a rigid structural piece with excellent thermal properties that helps insulate the LivingSpace sunroom. OSB is one of the most popular wood products in construction, and it’s used by a range of craftsmen working on anything from do-it-yourself jobs to professional projects. Similarities: OSB and plywood The best way to explain OSB is by comparing it to another commonly used wood product: plywood. OSB and plywood are fairly similar in terms of functionality and structure, and they’re both installed onto roofs, walls, and floors. Both products have similar structural performance measurements and standards. Additionally, OSB and plywood are both durable under a variety of different exposure settings, including Exposure 1, Exposure 2, and Exterior. The Exposure 1 classification is the most important, as it accounts for 95% of all structural panels. An Exposure 1 classification says that the wood used to build sub-floors and sheathing panels can be open to the elements during construction without compromising the structural properties of the panel. Differences: OSB and plywood The two woods are both strong choices, but there…
