 Any place around there. So what I recommend is if you're putting one of those in, pull the insulation back, go in, and then caulk and seal up everything between that attic space and the living space down below it. Now, if it's in the wall, use some of that fire caulking, that fire foam to go through and close up all those things. Not a bad idea anyway. But you need to stop any drafts from the conditioned space to go out there. Because what happens is you'll put on, you need to have more insulation
