I had the idea a long time ago to line the sides and top with refractory. I called Mark and talked to him about it. (This was a few years ago). He said he had already tried it and the issue was the refractory did not hold up, it cracked and fell apart. He said he had the ss needles in the mix of refractory. Seems to me if we line the unit over the hex tubes there will need to be a steel frame to support it. I am considering building a frame and lining the sides and top above hex with fire brick. Do you guys think this would make enough of a difference in performance to bother with? I am curious more then anything. My unit runs clean, my goals would be to decrease wood consumption, I would think the HEX would perform better with some type of refractory above it? Not sure if I have the ambition this year...
Bought my refractory and board from GM Refractories in Brighton, MI http://gmrefractories.com/index.htm

Jesse, I am hoping to achieve everything you mentioned with the new refractory, I am also hoping to be able to clean the hex now with out worrying about snagging the insulation above the hex...
Jesse said:I'm in the process of rebuilding mine now. Going to try something completely different with the insulation to where it wont be exposed to the elements of the fire. I don't like the way the insulation acts in the corners. ( collects creosote ) Basically what I'm doing would be like removing the insulation from the inside and wrapping the out side, only different. In my opinion it will work much better. I agree that long hot burns with no idle time would probably help this a bunch but I don't have storage and won't for some time. I'm documenting my rebuild and will post pics soon.
