I see, but it looks like you also used fiberglass between the access panel and the rigid foam. Shouldn't the foam be against the door, toward the warm side, like it is in your attic picture?
The foam is flush with the 2x4's on the door. It was done the same as the pro's did our other knee wall door. Right down to the foil tape on the edges and fender washers.
Sadly the insulation work is worthless for a few years as the room won't be heated until then.
The final step will be removing the insulation then priming the entire door front and back with a sealer/primer then putting on a top coat of white paint. I'm waiting on that because it's too cold to do. -- IF YOU FIND ANY MISTAKES IN MY WORK...Please consider that they are there for a purpose. I try to please everyone and there is always someone looking for mistakes!
