Installing Wood Floors
We removed the rotting subfloor and installing new plywood right unto the joists before installing oak strips. Advice whether to use 1/2 or 3/4 in plywood?

I think 3/4″ plywood subfloor would be better.Use screws to tight the subfloor and apart from it glue it to the joist.
I would do two layers of 1/2″ in alternating directions or one layer diagonal to avoid squeaks (from seams overlaping) with a spread of adhesive or green glue between. but i’ve been told that i overbuild things.
From my recent renovation experiences, 3/4″ plywood subfloor (no pressboard or particleboard to cut cost or corners!)
Lots oh glue… well, yeah, adhesive if you want to get all technical. sticky stuff that dries.
3/4″

1/2 is too flexible and SS is right, tongue and groove is best if you can get it
Also, a heavy duty construction adhesive on each of the joists as well
3/4″ subfloor. Glue the subfloor to the joists in addition to screws to avoid “creaking” noises developing over time. Also for more acoustic separation, lay down a layer of 1/4″ cork (or similar) between the hardwood and the subfloor. Not sure about T&G – thought that was more for a roof or if the floor was treated as a structural diaphragm or to prevent racking. I thought you use straight edge plywood and leave 1/8″ gaps at joints (could be wrong). Oh yeah – make sure you get PLYWOOD and not OSB or particle board.
You’ve removed the existing subfloor, right? Then 3/4″ plywood is recommended
Be sure to use toung and groove plywood for the subfloor and screw twice as many screws as you may think necessary. – keep the subfloor “tight” to the joists – do it now, can’t later.
