If the surface emittance is high i.e. 0.06 to 0.99 or Non-Reflective – can this material still be considered/classified as radiant barrier / reflective insulation?

A surface with an emissivity of .06 is still considered to be a reflective material, either as a radiant barrier or reflective insulation. Anything higher than .1 would not meet the ASTM definition of either a radiant barrier or reflective insulation.
