Quick question. I have an large flush wood insert by Travis Industries. Can I insulate the insert by putting roxul behind it, what will fit on the sides, and on top of it? I would not pull the insert out and just place the roxul directly on it. I am hoping to insulate the fireplace to keep the heat in the house and not going out from the external chimney.
Are there any downsides to this? Can it hurt/harm the insert? Thank you!
