Make the door of two layers of 1" foam glued together. Cut the inner piece to fit the whole window assembly, and the window hole in the outer face to be the frame the window and screen seal against.
A thinner outer layer of 1/2" foam might be better still, I'm planning a foamie this year, the doors will be framed in wood, and probably be skinned with 1/4" ply.
You could also cut through the door and add a frame of wood or foam to the outside of the door to seal the window, this way the support angles for the inside would be less obtrusive. I saw a barn with windows set into a 2x4 wall that way. There were no brackets intruding past the inside wall, just the top of the window when opened. The supports were simple diagonal strips nailed to the inner frame.
I think I understand what you mean. I do want to limit the amount the frame protrudes from the wall and I had thought to limit the frame to 2" thick so the windows will be flush on both sides, at least when closed. That leaves me with closed, a 1x18" opening at the top (wedge between the glass and screen,) or remove the glass completely for the full 12 x 18" oval.
I'm ambivalent about partially raising the glass and wedging it in place which would leave the end of it kinda hanging out in space. I should probably mock it up and see how bad that is.
The door is another issue, I may just not do a window there and put one in the wall on that side and two in the wall on the other side. Do (3) 1x18" slots seem like adequate ventilation?
