I am installing new contruction wood windows with an alum clad exterior in a humid climate (Wash DC). I am staining the interior and 3 coats of poly before installation. Should I put a coat or two of poly on the bare wood that faces the framing to block moisture. Or will the window/door foam to be installed after block the mointure? Doee this even make sense?

Don't worry about it, it's a non-issue. Poly won't stop moisture for long. Many window jambs are already treated at the factory, you don't have to add anything more.

I agree with hammer .. it probably won't matter .. but, after you finish finishing all the surfaces of the window, muntins, stiles and frame you can do the outside of the frame in heartbeat, .. then your done! I always seal both sides of the wood, window probably won't matter but then ..
ps .. they'll probably take 3 coats of poly to cover, so slap on 2, sand and then the 3rd, if you sand after the first you'll just take it down to bare wood .. and so on, and so on ..
So the vote seems to be 1 for doing nothing and 1 for coating the outside (although its not necessary). Any more votes?
I doubt it matters much. Far more important is following ASTM Standard 2112 for flashing. Google it, and you'll get pretty good details.Andy
