If one were to want to insulate his smoker, what is the best material to use, what's the cost (per sq. ft.), and where is it available?
I had a buddy that built his own gun safe and fireproofed it with some kind of stuff designed for the space shuttle interior. He could have bought a whole safe for what it cost.
