Rigid rock wool insulation panels like Roxul RHT80. It's good to 1,200 degrees and is readily available. You can get it at BBQ Smoker Supply
http://bbqsmokersupply.com/rock-wool-sm ... -oven.html or if you need different sizes at Zoro.com which is where I ordered mine through. I ordered one morning from them and it arrived the next day.

Do you have a sketch of this design? i just don't understand what you're doing with the bottom half. Did you run the numbers through the pit calculator?

I'm not trying to throw water on your fire so to speak, just want to help if I see a problem coming up since it is your first build.

Trust me any help or advice is welcomed. The bottom is more of a skirt. I did run it in the pit calculator. And other than the fire box being a little bigger than called for everything is at least at the measurements the calculator gave..

The back side of the fire box is closed up now with the opening to the calculators specs. The throat is about 20% larger then the opening off the fire box.

This is definitely an intresting build. Can't wait for it to flesh out a bit so I can see how it all works.

Yes the specs on it were kind of a dream, then when it was all put together; well the thought was if I ever have to actually fill this thing it will be a beautiful day in my world..

There are a couple things that have me concerned 1. The throat opening (fB to CC) opening looks like it is about 4" below the top of the FB top. That will result in the top of your FB getting much hotter than it needs to because of the turbulence in the draft. 2. The BP gap (the opening opposite of the FB end of the baffle plate) you said it is going to be bigger "The throat is about 20% larger then the opening off the fire box" than the throat. This will result in slowing the draft. 3. The space you have below the throat under the CC, appears to be 1/2 + the size of the CC. I have never seen this done but my thought on it is, this area will require a much larger fire to heat it then heat the CC with what ever is left. I would consider a plate under the throat opening going all the way across to the other end. Then the "skirt would really be just a skirt.

I hope this is taken in a good way, not beating you up about your build.

I appriciate the in put. However I spoke with a friend that is helping me and he has the baffle plate in already. The opening on the fire box however is going to be opened up higher. (closer to the top of the fire box) I am going to start a fire in it see how it pulls and if I have to (before any meat) will cut the skirt off the back and place the plate on it like you talked about.

Thank you for the help
