My townhouse has a basement, 1st floor, 2nd floor, attic. There is a shared cinderblock wall with my neighbor. In the attic at the wall, there appears to be a gap between this wall and the framing that I am guessing runs the whole length of the wall to the basement or at least to the top of the basement wall.
- Should I gap fill this with something like a pool noodle and spray over it with foam? (I don't know if the video picks it up but there was dust/cobwebs blowing around the open space near the wall)
- Should I do something regarding the roof end framing and fill that small gap with foam? I have soffits and a ridge vent if it matters.
Guess I'm just worried/wondering if this airflow is beneficial in some way to the rest of the house.
