Fireplace Air Sealing
I’m currently insulating our single level home in coastal California (95062). We had no insulation in the walls so I’m excited to get some rockwool in there.
When taking down the drywall around the fireplace, I could feel air coming through the brickwork and in a few spots I am able to even push a pencil all the way through into the chimney.
What is the best way to airseal the bricks? (fireproof sealant/foam, mortar?) From reading other posts on GBA it seems as though I should not add any insulation between the brick and interior drywall (even rockwool) which is too bad.
