Re: Material for a oven
I used the Firewall (Fire rated sheetrock) in the oven we built here. It works great, though if I had to do it over again, I would use the foil-backed insulation stuff. Definitely lighter, as well as has more 'R' value. After a few hours, the oven here gets kinda warm.
Lotsa learning going on. I had made a thread about it, when it was being made.
