I Have a house built in 1972. I'm currently 80% finished in installing a ceiling fan into my master bedroom.
I had an energy audit about a month ago, which revealed that I had "pretty good sealing" in my home, but found the classic attic/wall entry points, specifically, wall outlets and holes in the ceiling for light fixtures, were leaking air.
I've already bought and installed all of the foam outlet/switch sealers (like this), but I don't feel as though its sealing very well around the house. I'm also not sure what to do around the hole in the ceiling.
Googling reveals suggestions like this one, but doesnt specifically mention what can be done to seal a hole in the drywall around electrical fixtures (I'm concerned about fires) Any suggestions?
