insulation

[diablo14]

is there any kind of supply stores or something i could find locally to have insulation for my oven? i have been to lowes and home depot and they dont have anything.... anyideas would be great

I ordered my insulation, mineral wool, from a locally owned building supply store here in Western WA. Its used in the building industry around fireplace and stove chimneys. Some of the oven builders buy it from the likes of McMasters. Good luck! Fred

There may be some that disagree with me on this but I build my oven and used R-30 pink insulation and it works great, gets to 450 degrees in 4 to 5 mins and holds the temp great. I called owens corning before I made the decision to use it and the R-30 pink insulation is good up to 1200 degrees. Just make sure you get the unfaced, can't use the faced the paper wont take the heat, but as long as you go with the unfaced it works great. Hope that helps you out.

I orderd my mineral wool from McMaster Carr got to me about 3 days after i ordered it. I like it was only $10 something a sheet. I got the 2inch.

Hope that helps

Does anyone else have an opinion on this because I was wondering the same thing if it would work?

most of your house hold ovens use this type of insulation , it does work

I just had my oven fired up again and double checked the temp with an oven thermometer and it seems to be right, the R-30 seems to be working great.

Owens-Corning specifies an operating temperature up to 250*F for their fiberglass insulation. An interesting addendum states a break-down temperature of 650*F. While spun glass should handle temperatures in excess of 1000*F, it could be the binders used during manufacture that limits temperature. You should be ok using fiberglass for a PC oven but I wouldn't try to use it above normal powder curing temperatures.

Save yourself some money and just use R11. That's about all you'll get trying to compress 10 inches of insulation (R30) into a four inch wall. The more you compress the insulation, the greater the loss of insulating value. It's NOT the fiberglass that provides the insulation, it's the air gaps between the fibers.

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.

for once I felt like i got a pretty good deal. I called a few insulation places and told them I needed #4 safing rock wool. they just told me who I needed to call. I got mine for 90 bucks tax and all. My oven is 6x4x4.
