If the door had a bit of a redesign making for a railing at the top for a grooved wheel to track in it, then that steel up there would be recessed from the front plate casting. That's true at the bottom as well. That would allow you to better insulate above and below the door. It adds up. Currently the central posts at the top and bottom won't allow for insulation. It may make a fifty degree difference it temperature. That's a lot.
