According to Nachi.org, OSB has the below 4 advantages over plywood:
1. OSB is more uniform, so there are fewer soft spots, such as those that can occur in plywood.
2. OSB is less expensive than plywood. To build a typical 2,400-square foot home, OSB may cost $700 less than plywood.
3. OSB is considered by many to be a “green” building material because it can be made from smaller-diameter trees, such as poplars, that are often farmed. Plywood production, by contrast, requires larger-diameter trees from old-growth forests.
4. Plywood has a tendency to delaminate, especially in hot climates.
