Kynar 500 based painted metal roofing can achieve solar reflectance of over 70.

Solar reflectance index metal roofing.

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. Emissivity is a material s ability to release absorbed energy.

Also important characteristic to a metal building panel color is the ability of the panel to release absorbed energy called emissivity. Berridge s kynar 500 hylar 5000. Furthermore it doesn t store as much thermal energy as an ordinary roof. 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.

By lessening the demand for energy it decreases carbon emissions that cause pollution. Darker colors like dark brown have an average solar reflectance of 5 9 while white granules have a solar reflectance of 31 3. This is called the solar reflectivity index sri. The benefits of cool metal roofing cool metal roofing has many benefits beyond savings on energy costs.

Reflected solar energy allows the roof surface to remain cooler which means less heat is transferred into the building. Requirements and is calculated according to astm e 1980 using values for reflectance and emissivity. 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. Installing a cool roof can cut your energy costs while contributing toward a better environment.

Many homeowners elect a balance between solar reflectance and aesthetics. Cool metal roof colors are optimal for reducing energy consumption particularly where cooling loads dominate. The solar reflectance index is used for compliance with leed. Cool metal roofing coated with kynar 500 based resin is one way to limit the urban heat island effect.

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. 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.
