Can you use half inch plywood for flooring?
For instance, if the joists are 16 inches or less apart, a 1/2 inch of subflooring may be enough. In older homes, where the joists may be farther apart, you will need thicker subflooring for stability. This will require at least 7/8 inch plywood and 1 inch thick of OSB.
