What is Solar Reflectivity (SR) ?
Solar 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 solar energy and a value of 1.0 indicates total reflectance. Energy Star requires an n SR value of 0.25 or higher for steep slope (above 2:12) roofing and an SR value of 0.65 or higher for Iow slope (2:1 2 or less) roofing. For more information, please go to www.eneryvstar.qov.
What is Solar Reflectance index (SRI)?
The SRI is used to determine compliance With GBI requirements and is calculated According to ASTM E 1980 using values for reflectance and emissivity. Thermal emissivity (TE) a material’s ability to release absorbed energy to meet GBI Requirements, a roofing material must have an SRI of 29 or higher for steep slope (above 2:12) roofing and an SRI value of 78 or higher for low slope (2:12 or less) roofing.
