  7. Radiant barrier - Wikipedia

    en.wikipedia.org/wiki/Radiant_barrier

    A radiant barrier is a type of building material that reflects thermal radiation and reduces heat transfer. Because thermal energy is also transferred by conduction and convection, in addition to radiation, radiant barriers are often supplemented with thermal insulation that slows down heat transfer by conduction or convection.
