My pantry is close to the same temperature as the outdoors and I would appreciate any suggestions about what to do. The basement is finished so I'm trying to figure out what to do from the outside.
There are multiple layers of old siding beneath the shingles, the inner layer of which is rotting in places. And there are various voids large enough to fit a finger.
Can I "cap" it with a horizontal piece of rigid foam sealed on the sides with spray foam? Or do I need to take off some shingles to seal it with a vertical piece of rigid foam or something else?
