Reflected solar energy allows the roof surface to remain cooler which means less heat is transferred into the building.
Solar reflectance index metal roofing.
Berridge s kynar 500 hylar 5000.
The benefits of cool metal roofing cool metal roofing has many benefits beyond savings on energy costs.
Emissivity is a material s ability to release absorbed energy.
Furthermore it doesn t store as much thermal energy as an ordinary roof.
This is called the solar reflectivity index sri.
Leed requires a roofing material to have a value of 29 or higher for a steep roof pitch 2 12 and 78 or higher for a roof pitch 2 12.
Urban heat island a built environment where the large portion of dark absorbing.
By lessening the demand for energy it decreases carbon emissions that cause pollution.
Kynar 500 based painted metal roofing can achieve solar reflectance of over 70.
Cool metal roof colors are optimal for reducing energy consumption particularly where cooling loads dominate.
Many homeowners elect a balance between solar reflectance and aesthetics.
Also important characteristic to a metal building panel color is the ability of the panel to release absorbed energy called emissivity.
Cool metal roofing coated with kynar 500 based resin is one way to limit the urban heat island effect.
New technology helps to close the gap between aesthetics and solar reflectance.
Berridge metal roofing is cool and sustainable the high reflectivity emissivity and solar reflectance index sri of berridge metal roofing helps mitigate the heat island effect.
The guide to choosing a cool roof.
Heat island effect roof.
The solar reflectance index is used for compliance with leed.
The solar reflectance index sri is a measure of the constructed surface s ability to reflect solar heat as shown by a small temperature rise.
Installing a cool roof can cut your energy costs while contributing toward a better environment.
It is defined so that a standard black surface reflectance 0 05 emittance 0 90 is 0 and a standard white surface reflectance 0 80 emittance 0 90 is 100.
The cool metal roofing paint resin formula formulated by sherwin williams or another paint supplier contains innovative solar reflective pigments which is the key differentiator.
