Sri Roofing Materials

Sri measures the roof s ability to reject solar heat defined such that a standard black reflectance 0 05 emittance 0 90 is 0 and a standard white reflectance 0 80 emittance 0 90 is 100.

Sri roofing materials.

The high reflectivity emissivity and solar reflectance index sri of berridge metal roofing helps mitigate the heat island effect. Building designers and developers that are pursuing the heat island reduction credit for leed certification require documentation of the solar reflectance index sri for their project s roofing materials shade giving structures and paving materials. California s building energy efficiency standards for residential and nonresidential buildings title 24 part 6 contains requirements for the thermal emittance three year aged reflectance and solar reflectance index sri of roofing materials used in new construction and re roofing projects. Sri lanka s marketplace for roofing materials is here to help you choose the best roofing products suppliers and brands for any construction site.

This measurement can be used as an indicator of how hot shingles are likely to become when they re exposed to the sun. The solar reflectance index or sri is a calculation using the aged solar reflectance and thermal emittance measurements of the asphalt shingles materials. Take a look at the top roofing materials and see what might be right for you. To meet leed requirements a roofing material must have a sri of 29 or higher for steep slope 2 12 roofing and a sri value of 78 or higher for low slope roofing.

Cool metal roof colors are optimal for reducing energy consumption particularly where cooling loads dominate.
