what should use for sub-flooring and thickness that won't break the bank? Note:

I'm turning my attic into a finished additional room. Iwas wondering what type of sub-flooring material and thickness to use that won't break the bank without sacrificing decent quality? I've decided to use 1/2" drywall for the walls and ceiling.

The biggest problem you might encounter isn't the subfloor but rather the floor (or old ceiling) joists.  More times than not, they aren't sized to support the live load of a living space, so you can end up with a pretty "bouncy" floor.  You might want to think about sistering in larger lumber.  You'll loose a bit of headroom that way.

 

If you don't want go that route, I'd use a good quality 3/4" plywood subfloor like GP's Plytanium.  Glue and screw.
