Good place to buy plywood in Milwaukee?

Senn plywood and door, in Menomonee Falls (?) would be a good place to start.

I don't think "standard" ply is going to be significantly different anywhere. Specialty place such as this can probably help, but quuite likely will have to go w/ better grade.

I found a web page that said there's a difference if the grade stamp has the word "exterior" or not-- eg, sometimes ACX is assumed top be "exterior" grade when it's not (supposedly the "X" means something else). I don't know how that works out in practice.

I was trying to avoid the better grades because appearance is not important (as long as one side is more-or-less smooth). But the last piece of plywood I bought at the BORG wasn't fully laminated...

The phone book says they're in New Berlin, on Glendale Dr (which is a discontinuous road-- at least four different sections that don't connect to each other). Looks like maybe just east of Calhoun Rd. I'll check it out.

All the 'exterior' means is weather reistant glues rather than not...

The amount of internal voids in construction-grade ply isn't related to the face grade--only the load rating. My point was that you won't find any ply that doesn't have voids except cabinet grades.

PTX is void-free and should be stock at pretty much any real lumber yard. It's utility stuff, and should be pretty much the same price at all the real yards. Just let your fingers dothe walking through the yellow pages.

Alpine Lumber is a *big* dealer.
