What Kind of Sheeting?

I have inherited some steel clad sheeting made of what looks like some kind of treated particle board sandwiched between metal on one side and foil on the other. Was wondering what it was used for? I'm thinking it's some kind of fire resistant sheet. I'm redoing the walls inside my pole barn shop and the previous stove was close to the wall and need to know if this stuff would be suitable directly behind the coal stove I plan to put in.

Any one know what the sheets are?

I would only use it as a heat shield if it had some type of certification printed on it stating that’s what it is.

Its possible its asbestos also.

Just want to find out it's true purpose first. If it is in fact built for fire resistance and any kind of heat shield, I will use it. It for sure would be better than the OSB I'd use instead. Also I'm curious because I have never seen this stuff used before.

Who ever had this shop before me had a bunch of sheets of this stuf mixed with, plywood, sheet rock, OSB and even some old chalkboard covering the walls. I'm sure it will be all right as he had 1/2 this stuff and 1/2 sheetrock behind his stove.

This is what is up. The brown, blue, tan sheets are all of the metal clad sheets.

It’s hard to say what the original purpose was. They use metal clad wood for trailer doors. Where I once worked they would get them in a big sheet, a little bigger than 4X8 plywood and they would cut them to size and fit the weather-strip on the edges to make a replacement trailer doors. This was the same stuff the manufacturers use, white painted aluminum on the outside and mill finish on the inside.

To be a heat shield it should have a non-combustible core like gypsum.

These are 4x8 sheets and heavy as hell. Probably 7/16" thick.

The thin foil is radiant barrier and would be placed so it's facing the heat source. Without knowing what the material is sandwiched I wouldn't use it. It could just as easily be for refrigeration to keep heat out of something and not made for higher temperatures.

You should have something like fire resistant drywall, hardy board etc. If it's really close add some metal sheeting that is stood off from the drywall about 1 inch , have a gap at the bottom and top so the air can flow between it and the drywall.

Could very well be a sign making product. Take a small piece and put it on top of your stove and watch it . If it doesnt start on fire yer good to go. As Richard mentioned don't put the steel side toward the stove. That pup will walk right off the wall.
