How to insulate around electrical line entering?
Just got some garage light fixtures put on our unfinished garage.
The backing plates cover the pretty well the holes on the exterior side.
However, I'd like to insulate & cover the back side hole where the electrical line comes into the unfinished garage walls & studs.
A few board members recommended - plumber's putty on another entry point before here (outside receptacle) over foam.
I've also read silicone caulk - but I think this is too big of a opening to use caulk on.
