Could you reference somewhere in the video your question references? I'm going to assume your talking about what I used to install the concrete backing panels, but I am not entirely sure that is what your asking?

@@farminginthehighlands1205 thank u for the fast response

Don't quote me on this, but I have burnt tin roofing in my fire pit outside at my cabin, so I would not stake my life on it. I am not sure metal of that thickness is recommended but yes I have seen people use 1/8 of an inch pieces of metal as back plates. The Backerboard that I installed is considered to the 'up-to-code' requirement if you want to get insurance on a building with a wood stove. Now I know that different wood Stove have different space requirements from the wall and I also know that US & Canada have different standard. Did that point you in the right direction or answer your question?

@Farming in the Highlands metal roofing won't burn. What I mean is that it won't burn by itself by just introducing heat to it. You literally have to have a flame for it to melt. Like wool is considered to be non flammable. It will burn, but as soon a you remove the flame, it stops.

@@sonsofliberty3081 Yes you are correct it will not burn by itself, now I don't know what distance from the wall it would be considered as safe. Because it is metal and is fairly thin, I would assume it has a rating of some kind indicating it's effectiveness against melting through induction.
