Chimney & Fireplaces/insulating around flue pipe


hi, I was wondering what I could use to insulate around my insulated pipe going through a solid concrete wall?  There is about half an inch to an inch all around the pipe and you can feel the draft.

Hello Lance, most pipes have a "Trim Ring" that you can install around it, if not you would have to find out what kind of pipe you have, I assume it is going Horizontally through that wall an if so in most cases you can just use Cement or a high temp silicone.
Hope this helps
Have a Safe and Happy Thanksgiving
