Discovered that the attic access hatch isn’t insulated, which honestly isn’t surprising given when it was built. No ladder system. I’m working on cutting up some foam boards to glue to the backside. Hopefully it will reduce how much is radiated through this barrier.

That would be a great piece to the full solution. I’m trying to get the R-value to at least 25 (40 being ideal), and the reflective stuff on top or bottom would probably help slow down thermal transfer.
