I will be framing out my basement with steel so the bottom track will be on the concrete slab.
Is it required to put some sort of vapor barrier between the slab and the track? I couldn't find anything in the code that indicated it was required but want to make sure I pass inspection.
If it isn't required by code, is it recommended? My gut says it's unnecessary since the metal is galvanized, but I've seen arguments for and against it.
If some sort of barrier is required or recommended, what would you use and how would you install that?

I'm not aware of any requirement or recommendation to use a vapor barrier between a concrete floor and wooden framing, so I can't see why there would be one for metal framing.
Pressure treated lumber could be used for the sill plate if you were doing it in wood, so I'd think that would have a similar water damage resistance to galvanized steel studs.
