Hi there, I'll be a new wood stove owner come October - I ordered a Woodstock Soapstone Progress hybrid. It's a new installation, there is no stove currently in the home. I will be placing it in the middle of a wall, as the floor there is reinforced with stonework and had a fireplace there years ago but the owner before me took it down. While the stove does not need a rear heat shield more than the one that is coming on the stove, I would like to put one up to reflect some of the heat better and make it a focal point in the room. I was thinking about either corrugated metal roofing materials, or the tin ceiling panels. My question is, can I get the ones that already have paint/finish on them or will they smoke/off gas from the paint coming in contact with heat? Or can I only use untreated metal? I can't seem to find this answer anywhere on the web. Thanks for any insight. I was hoping to use white panels/roofing.
