Sorry about that. I was more focused on the fire pictures than the author. Who ever's fire it was it made me take a close look at my smoker.That wasn't my fire! I don't even have a smokehouse yet!
I ended up only putting a single 16x16" tile under the element kit. I had to cut a square on one end of the tile for the element cord and one square on the other side for the air vent. This element kit comes with a round sheet metal plate with a support platform that the element sits on, so there is air space between the element and the metal plate. So on the bottom of my smoker it's element-> 1" air space->metal plate->1/2" ceramic tile->aluminum sheet metal->1/2" concrete board->insulation->siding.Looks great Eric! Just wondering about the ceramic tile, are you going to put it on the bottom of the smoker and sit the element right on it, or have an air space in between tile and the smoker?
