I have a question regarding a tough spot I have in my pantry. It is what I call a knee wall, but that is only because I am not quite sure what else to call it. It’s a small access area, where there is some wiring, Internet router, etc, above a wall in the pantry. The attic is right on the other side, with fiberglass batts kraft paper showing. There is an access door to this small area, which, I was getting ready to attempt to air seal as you would an attic hatch. However I am not sure how best to do this. Would it be better to air seal along the fiberglass batts, or at the access door? It is a small space, and almost impossible to get a drill in to install any drywall or rigid material. It would be easier to air seal at the access door, but I’m not certain if this will create any issues.
Any help is much appreciated.
