Thanks for the info Ken, Yea the Guy at Owens Corning said it would be good up to 1200 degrees, but who knows, LOL.
I went with the R-30 because it was the cheapest that the Home Depot here had, $14.37 a roll, I used 2 rolls on my oven, I didn't figure $30.00 was to bad. The R-30 that I used was 9" thick, it wasn't to bad getting in there it seem to smush down pretty good, but I didn't know about the air gap thing, but like I said it seems to work pretty good.
