Are radiant barriers tested by qualified independent testing agencies or governmental agencies?
The Florida Solar Energy Center at Cape Canaveral has tested radiant barriers in both small scale laboratory and full scale building models. Their results indicate that radiation barriers provide significant resistance to heat transfer. Current tests conducted by the Tennessee Valley Authority and the University of Mississippi support the findings at the Florida Solar Energy Center. Northeastern Illinois University conducted winter tests in residential and commercial structures using infra-red thermograph photography. The photos showed significant resistance to heat transfer over the regular insulation. Reliable individual brands of radiant barrier products are tested by the American Society for Testing and Materials (ASTM) and result in verified and uniform product specifications that can be trusted when researching a radiant barrier to purchase. All RadiantGUARD® radiant barrier products meet the Standard Specifications for Sheet Radiant Barriers for Building Construction Applica
