T&G Plywood over Stud Walls

TheatreFace: Over the last few weeks I’ve examined built-up platforms, but in some situations, simply using plywood over stud walls can be an efficient use of materials and labor. Slapping tongue-and-groove plywood down over stud walls spaced every two feet harkens back to traditional residential construction where subfloors were laid over joists spaced every 16 to 24 inches; it was—and still is—a solid, reliable flooring construction technique that costs relatively little in either materials or time. Using ¾” Sturd-i-Floor tongue-and-groove-sheets with stud walls running perpendicular to the face grain every two feet will achieve the same 50 pound-per-square-foot load previously discussed with other panels.
