OSB or Plywood?
Had 8x10 barn-type storage building erected a few years ago. Its' floor is .75" plywood which I sealed with a HD sealer. Intend to add another building but this will be a gable-type for the tall side walls. This builder uses .75" OSB for flooring. Any OSB I've ever used eventually sagged and those uses were indoors. I want a flat floor now and into the future. Has OSB changed somehow where it will not sag?
