Jerry. I have been running my oven without insulation for the last six months (no time to complete- as yet). Found the oven was fine for short roasting (2 hour max) but in winter it lost too much.

A friend has a IR-laser thermometer (you just point and click) where you can measure anything from burning wood (~650 deg. C) to the exterior cladding (~5cm thick) at full soak (60 degC after 2 hrs). My point is that even if you put the fiber bat insulation directly onto the cladding it should be able to handle it, but if it exposed to the weather you would need to cover it.

Having said that, I would still go with the vermiculite. I am just about to insulate and will see how much things improve.

Good luck.
