What did you use for those insulative "bricks"? Looks like foil faced somethingorother. I started with just foil faced foam as the inside of mine, but it couldn't take the heat, and didn't insulate well enough. I added a layer of fluffy fiberglass, but then it shed "hair" on the parts. I have since added a layer of foil, but it's not perfect. Mine's about the same size as yours but electric, and since I've added all this insulation the interior has gotten smaller.
Make sure you keep a close eye on the temperature.. too cool and it won't set (carb cleaner washes it right off).. too hot and it wrinkles/bubbles.
Build detail:
Frame is built from steel studs 3.5". interior of oven is faced with 20gauge steel, the brick look is stamped in to the steel. within the frame "rockwool" board insulation is placed(it is 2.5" thick and can with stand 800 degrees, used in comercial ovens) Outside is the stamped steel again. a digital thermometer will be installed soon.
