Sorry for the new thread but I have so many questions going in my original thread I though I should start another one a little more basic.


I am going to start building a plywood smoker. I was thinking of 1/2" plywood inside and outside of a 2x4 framed box. My question is what can I use to insulate between the sheets?


Would this work?


Or what about a rigid foam type?
