They have medium relfectivity and poor emissivity 15.
How do radiant barriers work with metal roofs.
Even on a bare metal roof when sunshield is used if it is 85 f outside then the surface temperature of the metal will be 85 f with sunshield rather than 160 f without sunshield.
Radiant barrier is a highly reflective material typically made of aluminum which blocks the transfer of radiant heat by reflecting it away from its surface offering a permanent way to reduce your monthly utility costs.

Galvanized and galvalume metal roofs are hot roofs.
Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction.
Increasing summer energy consumption and cooling costs.
It also prevents corrosion and surface deterioration.
