Huge difference! Your temp/air & draft control becomes much more predictable and fuel consumption goes way down. Wish I had and some day probably will insipulate my firebox.

I can understand an insulated cooking chamber where you are trying to reach and maintain temps.
To me, it seems the heat is leaving the firebox at a rate determined by the dampers and would only be marginally effected by outside temps.
