Thanks much! didn't think a heat gun would produce that much heat. The gun locker is a good idea, have seen several on the web like that. I have 40 boards of ridge RMAX Plus 3, but it is only rated up to 250F. I thought about the old stove insulation, but it isn't ridge and it's bulky. There is also n insulation used in vehicles that I saw saw in DiY ovens, but expensive for the amount I need. I am going to contact McMaster CARR. They have insulations that will cover just about every application. Then have to look at how much it costs. I thought about the old stove insulation, but it isn't ridge and it's bulky. I need one layer of insulation glued or screwed to the inside walls and don't want to encapsulate it. After I find a suitable insulation and assemble everything I'll post the information. Thanks again.
what about rock wool? good up to 2150F. $52 for 60 sq/ft.
heat guns would be perfect. i use one to heat the flue before i build a fire so i dont end up smoking out the house.

The only problem with rock wool is that is too thick. It would reduce the inside measurements of my cabinet from 21"x24" to 17.5"x21.5" plus it would have to encapsulated by putting additional sheeting over it to prevent fibers from blowing around in the oven and getting on the cerakote.
I'll have to try the heat gun trick in my fireplace. Thanks

The insulation I got, I call rigid but is really pressed fiberglass? It's not a roll but maybe rigid is the wrong word. The main thing is that it is fiberglass and I noticed the first time I used it that those little fibers will get in the finish. I sealed each seem with the red high temp RTV from Autozone. That improved the temp control and removed the problem with the lose fibers. Also gave it that racing look with the red pin stripes.
