Should I use plywood or T&G OSB for subfloor in new addition I am
building? The addition is on second story, floors are 2 X 8 16 O.C. I
checked prices and 3/4" T&G OSB is more than twice cheaper then 3/4"
plywood. I will have hydronic heated floors. There will be another
plywood or OSB subfloor on top of base one with grooves for PEX
tubing. My original idea was to use OSB everywhere except for bath
subfloor where I was going to use plywood.

OSB is slightly more expensive than plywood here, so I was planning on using
plywood for the room I'm building over the garage. I wanted to use plywood
anyway because I'm not planning on finishing the floor right away (it's going
to be used for a shop). Plywood, with a coat of floor paint, should be easier
to sweep clean than OSB. Before I sell, I'll turn the room into another
bedroom.
The Advantech stuff I talked about
earlier and someone explained that is
was an OSB-type product has a very
smooth surface. It's nothing like the
OSB stuff you find at HD or Lowe's. It
seems to be much harder than the regular
OSB stuff. I know my builders
carpenters complained about how
difficult it was to drive nails or
screws. And, as was pointed out, it has
ratings for various spans, like 16" or
in my case 19.2".
