Hi Guys,

Thanks so much for the responce. I will try and provide you more info....
The oven is constucted of all brick/concrete with blocks used as the foundation. I am not sure what type of fire bricks we used, we went to the local supplier and ask for fire brick. Didn't realize there was a difference.

After a couple of hours of burning a fire the exterior bricks do become warm to the touch. If I need to insulate how should I go about doing it?
I really don't have any access to the interior of the structure (as it has been sealed with bricks) anymore.
