Solar Reflectivity (R) & Solar Reflectance Index (SRI) by Color
WEBSolar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR value is a number from 0 to 1.0. A value of 0 indicates that the material absorbs all solar energy …
What is SRI or Solar Reflectance Index? - NEOtech Coatings
WEBCoatings that block infrared heat is the ultimate standard we should seek. This means understanding paints and coatings which offer a U value as evidence of the amount of heat transfer in W/m2/k or Total Solar Reflectance is the only appropriate measurement to manage solar heat absorption.
