My question pertains to an upcoming job. Joist spacing will be 16" OC TJI and subfloor will be 3/4" ply. Flooring is TBD but will probably be either 3/4" hardwood or ~1/2" engineered. I believe the National Wood Flooring Association recommends a glued 5/8" + 1/2" subfloor combination for a parallel application. What is the best approach when joists and flooring run parallel and squeaks are unexceptable? Do you avoid this scenario like the plague? Not a big deal? Thanks.
