It's a plate steel box within another steel box. There is a 2" gap all around (except the door) that is filled with 2" Roxul mineral wool. Its fire rated. I saw a build were a guy had his bare hand on top of the fire box with the fire going inside. It will use less fuel. We plan to use thicker steel on the door & back.
