Please see our Silvaris custom services page.
What's the difference between OSB and plywood?
The main difference between OSB (oriented strand board) and plywood lies in their composition, performance and applications. OSB is made by compressing and gluing together layers of wood strands in specific orientations, creating a dense, uniform panel. It is often more affordable than plywood and performs well in applications like subflooring, wall sheathing and roof decking. However, OSB is more susceptible to moisture absorption and swelling at the edges if exposed to prolonged wet conditions.
Plywood, on the other hand, is made by gluing together thin layers (or plies) of wood veneer with the grain of each layer running perpendicular to the next. This cross-grain construction gives plywood greater strength, stability and resistance to warping compared to OSB. It is also more resistant to water damage, making it a better choice for applications where exposure to moisture is a concern. While both materials are widely used in construction, the choice between OSB and plywood often comes down to budget, project requirements and environmental conditions.
