Given that the re radiating of heat from the wall to the interior
depends on both emissivity and the 4th power of the absolute
temperature of the wall  just insulating the wall will have a bigger
effect even if this means the emissivity is lower.

Downside is that in keeping the metal surface hotter you are probably
lessening its life.
