Is "Radiant/Reflective insulation" better then fiberglass in a metal garage?
Answers:
The standard in the industry is batt insulation, the wrapped type for metal buildings and I would think anything else would be a step up in quality and thermal performance. So I would answer yes it must be.
But, I think you are asking if spending more on insulation is worth it, maybe not if the space is only used and heated some of the time and not always.

You should use something like a hard foam board. My husband is a builder and I know you have to worry about condensation on metal buildings Just call a local builder and ask.

in a hot climate (i'm in florida) it's better since it's denser and keeps the heat out better...it controls moisture in a metal shed better too
