We purchased a home and after moving in we found out that inside the master closet, a small door has been added to access a portion of the attic.
However, there is no insulation and my closet is very cold in the winter and very hot in summer. I'd like to fix this, as it's rather silly and inefficient. The door is hollow and quite flimsy.
Any suggestions on how I should fix it? Should I have an insulated door installed or can I have the hole patched up and insulated?
Appreciate any suggestions. I've attached a couple pictures.
Edit: for gooder grammar
