EcoRenovator - View Single Post - I bought a commercial -20 freezer to make into a powder coat oven.

Either Rockwool or fiberglass.
But I am leaning towards Rockwool.
You out gas at 450 degrees so either one will work.
The powder coat cures @400 degrees.

It looks like fiberglass. To get Rockwool I have to order 3 packs. No one here stocks it.
I can do it much cheaper with fiberglass. One pack fiberglass $37.48.
That one pack will be enough. That will work for this oven.

Some of the scientific freezers can store flammable storage. Mine is not that type.
I wish it was that maybe I would not have to re-insulate. It will be a pain but I think it will make a nice oven when I am done.
It will also keep my build cost low that is important right now.

I have a standard house oven right now. I will be gutting it and putting its heating elements in this one. For now I will just use its controls. This should work good in a oven this size and will keep cost down.
