Re: WOOT! found a Supplier for Rolux Mineral Wool!
I did my oven in 2 inch. But kind of wish I would have done it in 4 inch. But the 2" was available and I had 2x2 square tubing, so that set my size. But even if you do 2", it works okay, I just think (now) that 4 is better. I have some heat loss on the outside as you can feel the heat on the outer skin. Two inch thick is certainly cheaper then 4". So pocket book may also dictate.
What is the wool going to cost you?
