Hey everyone, I have a few questions, I finished my oven but in the process I forgot a very important step concerning my oven floor. I forgot to use insulation under the oven floor, I used two layers of fire bricks and the oven is already complete with dome so itís impossible for me to rip apart again. Does anyone have any ideas what I can do to or build to rectify this large error? Iím desperate, I know how important the insulation is and I feel really stupid to have forgotten it. Also, I think my doorway is to large which in turn is letting out smoke and not efficient for retaining heat. The door I think I can fix quite easily but the floor I need advice from the experts. Please any advice is better than no advice.
