Thank you so much for your reply. This is what I had in mind. I was hoping to not have to deal with drywall, but I'm sure its best. Now my main question would be. If I stud it out with 2x4's, the walls will stick out beyond my window casings by 1/4" before the drywall. ( Because I have no studs in the walls, my windows casings stick out 3 1/4" into the room.) I know I can bring the window casings out more to even it out, but was wondering if it would be possible to fur strip it out and use foam board instead. If I did would I need a vapor barrier just behind the drywall? Or would the R -value just not be worth doing the foam board route? I'm just looking for the simplest way to insulate with no moisture problems.
Thank you...
