What are the two terms commonly encountered when judging reflective insulation?
As R-values are used to measure the effectiveness of mass insulation, Reflective and Emissive ratings are used to measure the effectiveness of reflective insulation with radiant heat. A high Reflective value helps block more radiant heat and a low emissive value means the insulating material releases less of the heat that it absorbs. Better performing reflective insulation like rFoil™ is made from 99% pure aluminum for very high reflectivity and very low emissivity.
