How to insulate around a chimney pipe?
I have a fireplace insert in my basement. The pipe comes out of the wall, into the garage, and up to the roof. I am reinsulating this wall and I need some advise on how to insulate this. I have added a picture. I was thinking of doing some better framing around it and maybe use rigid foam insulation, but I read that building code requires a 2″ gap around. When I took the old insulation out(yellow, unfaced) it was just tucked around the pipe. What would be the best (and right) way of doing this?
