    I have a masonry fireplace with an external chimney. We recently added glass doors to the fireplace. I need to improve the seal around the doors and I'm wondering what the best material is to use.


    Fiberglass Insulation with the facing paper ripped off of it is OK. If the cracks are small..hi-temp silicone caulk (500-700 degrees) is good.
