To accurately compare different radiant barriers, the most important specifications to consider are REFLECTIVITY and EMISSIVITY values. Radiant Barriers have a reflectivity value of 97%, which means they block 97% of the radiant heat. The very best reflective paints only have reflectivity values of 75% or less. These paints also typically require very thick applications (up to ), and have a limited lifespan. Radiant Barriers are permanent. Radiant Barrier products also provide emissivity values of .03 (3%). The best reflective paints yeild emissivity values of .25 (25%). This means that reflective paints allow 25% of radiant energy to pass through. Radiant Barriers only allow 3%. The lower the emissivity, the better the product reflects and redirects radiating heat.
