That makes perfect sense! Thank you for your detailed response David!

I use a very similar solution to David but use vermiculite board for the backing, I use vermiculite and metal for the inner door and vermiculite and wood for the outer door.
vermiculite board is used to line wood burning stoves and is readily available at associated stores.

That sounds great for the Stainless or Aluminum, Thanks Mark! Any suggestions about the insulation material if I can't get calcium silicate???

The aluminium is only for my outer door. Aluminium does not play that nicely with heat. For insulation, encapsulated in the steel box on the inside of my wooden door, furnace blanket works really well.

Got it. thanks Mark! I'll probably do two doors, a stainless steel sheet with no insulation and a perlite/refractory cement like what David described.
