ORNL has not tested unpainted aluminum roofing materials but has measured the performance of bronze (PVDF resin) prepainted aluminum. Data indicate a reflectivity of 0.07 and emissivity of 0.87, however, with prepainted metal roofing, the substrate has no influence on the exterior surface reflectivity and emissivity.
