Dryguard OBS ¾" T&G sheets vs. Pressure Treated ¾" T&G Plywood for outdoor shop floor?
I am getting ready to build an outdoor workshop and am concerned about which flooring material would be best for termite protection. I understand the water resistant qualities of Dryguard OBS 4x8 sheets for sub flooring but have not seen recommendations for use as flooring in outdoor workshops or storage sheds. I live in a wooded area and will be constructing the building on a foundation of 6"x6" PT posts with all PT floor joists and supports. My concern is that the OBS floor may be a weak leak as far as termites go. Any thoughts would be appreciated. Thanks.
