ROOFING ARTICLES WITH REFLECTIVE THIN FILMS AND THE PROCESS OF PRODUCING THE SAME

摘要

A roofing article is prepared by applying a thin metal or metal oxide film to a base substrate. The thin film has greater than about 80 percent transmission of incident radiation having a wavelength between 300 nm and 700 nm and greater that about 60 percent reflectance of incident radiation having a wavelength between 700 nm and 2500 nm
