Does sealing rim joists slow the flow of air into attic?
Will sealing the rim joists in my basement significantly slow the stack effect or will the house just begin to pull its makeup air from other areas in the house instead?
Similarly, would sealing gaps from inside the house also slow the stack effect such as around hvac registers, ceiling fixtures, outlet boxes etc?
Due to the difficult layout of my attic with ductwork everywhere, I’m trying to do as much as I can from the accessible portions of my home.
However, I don’t want to waste my time trying to seal things from the inside if it’s not effective. I figure if I can’t seal it at the top, maybe I can choke it at the bottom? However, I obviously can’t access head plates from inside the home. Thanks a lot!
