I am in the process of replacing the secondary burn baffle on my 3cb. Since the top of the stove is open, I’ve been toying with the idea of adding a layer of ceramic insulation over the top of the baffle to help keep more heat in the firebox, or so I’m theorizing. Does this seem reasonable or am I just messing with the designed thermodynamics? I have a big roll of 1 inch ceramic wool in house.
