is it better to put the windows in the recess of the stick frame or to put them straight flush into the masonry? it's a barn, and the decorative masonry wall would not be load bearing.
I'm not sure if I understand the question. If you already have wood framing in place, usuallly windows are installed between and attached to the studs (which you're calling "stick frame"). Usually some type of exterior sheathing is attached to the exterior of the studs. The brick (or masonry) is on the exterior with a gap between the brick and the sheathing. Windows usually project about 1-1/4" past the sheathing into the masonry opening, which is enough to cover the gap between the masonry & sheathing.
