If you are having difficulty locating leaks, you may want to conduct a basic building pressurization test:
This test increases infiltration through cracks and leaks, making them easier to detect. You can use incense sticks or your damp hand to locate these leaks. If you use incense sticks, moving air will cause the smoke to waver, and if you use your damp hand, any drafts will feel cool to your hand.
The Rim-Joist is often a place homes suffer from large amounts of heat loss. There is only 1.5” of lumber covered by siding that separates you from the elements outside.
A thermal imaging sensor can be used as well, to help locate places in your home where the thermal envelope is not fully enclosed and sealed.
