I live in southern Canada and am having trouble with cold coming in around the fireplace. I have a metal fireplace which uses outside air for combustion and it works very efficiently when lit. The problem is that there is no insulation between the wooden chimney chase and the metal of the firebox so it becomes very cold when there is no fire. Also drafts come in between the firebox and the brick surround in the house. I need some ideas about how to seal the small gap between the metal and the brick, and how to insulate the chimney chase without creating a fire hazard.
Thanks for the input.

The only way to insulate your chase is to use the material of your choice in the wall cavities, then cover the interior with at least one layer of 5/8" type X drywall with all seams taped. Difficult to do once the house is done.
The fireplace to brick gap can be sealed with silicone caulking.
