Masonary Fireplace Insulation

I have a significant air draft around my fireplace and need to safely insulate. Per my county code, a 1" air space is required between the fireplace and wood studs. A wood moulding is the only thing between the fireplace and sheetrock, but it's not stoping the outside air from entering...

Any suggestions?

Hi Adaven and welcome to the forum.
Yes, it is difficult to seal and insulate while maintaining an air gap. I had always used 2", so one is already a bit easier. When air sealing around chimneys, we use sheet metal and seal it to the wood and chimney with a can of fire rated foam. My concern would be, that some insulation is needed as well as blocking the air. You might go back to the county code folks and ask if some fiberglass would still meet their air space requirement.

In addition to inside, check how it is trimmed outside. If you can air seal that gap as well it would help.
