What to use to insulate a smoker?

[southensmoker]

Thinking of buliding a smoker and would like to have it insulated.  It will be a double walled.  Would should I use to insulate the space between the inside wall and the outside wall?  Thinking the space will be 1.5 in. 

Thanks

Duh, I did a search for it and found Kaowool.  Disregard unless you would like to add more info.

Thanks

Kaowool is the shytz...i have used that in that past at different jobs with the last one being in a foundry. This stuff is great!! wont burn even at 2900+ deg.  Stuff we used was about 2 in thick but im sure you can get it thinner.

Wont burn and a great insulator. Cant go wrong!!!

Do a search under the build forum for BBQEngineer - he buit a double walled smoker he named The Iron Maiden and had some great play-by-play steps.
