Take a look at the top roofing materials and see what might be right for you.
Sri roofing materials.
Cool metal roof colors are optimal for reducing energy consumption particularly where cooling loads dominate.
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.
The solar reflectance index or sri is a calculation using the aged solar reflectance and thermal emittance measurements of the asphalt shingles materials.
Have you been thinking about updating your roof but don t know where to start.
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.
Berridge s kynar 500 hylar 5000.
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.
This is a state of the art polymer roofing sheet made of a special layer of asa material and pvc through a production process with the latest cutting edge technology which gives many more benefits to the customer.
The high reflectivity emissivity and solar reflectance index sri of berridge metal roofing helps mitigate the heat island effect.
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.
