Just putting the finishing touches on my wood fired sauna and am wondering if galvanized metal is suitable for a heat shield. Wondering about potential of nasty off gassing due to the galvanizing process, especially in a hot confined space ?
Is galvanized corrugated metal roofing ok for a heat shield

If used as a legitimate NFPA 211 heat shield there shouldn't be an issue. The heat shield temp would be far below the point where the zinc would off-gas.
Thanks for your responses. I am planing to fasten the galvanized to the cedar clad wall with spacers leaving the appropriate gaps at top and bottom and have the stove situated with proper clearances to WETT standards.
With proper clearances, you should have no issues with that tin. As you said - make sure you have the bottom gaps figured in to the build as well.
