Weathering and appearance variation, including color, sheen, and spangle, is common in non-painted materials and is not a cause for rejection. For consistent appearance, choose a paint- finished product. Colors on this chart are close representations of actual metal color, limited by printing and viewing conditions. Color matching optimized for outdoor viewing.

Choose an energy efficient paint finish.

Solar Reflectivity is the metal panel’s ability to reflect sunlight. This characteristic of metal roofing is the most important in terms of energy savings. Cool metal roofing reflects much of the sun’s rays, making the surface of the metal much cooler than material with a lower solar reflectivity rating.

Emissivity is the metal panel’s ability to release absorbed heat. A low emissivity rating means the material will be hot to the touch (it doesn’t release the heat), while material with a higher emissivity rating will be cooler to the touch. Therefore, metal with a low emissivity rating retains heat and may be more desirable for a cooler climate, while a high emissivity rating reflects heat and is more effective for saving energy in a warmer climate.
Solar reflectance values are determined by means of a solar spectrum reflectometer in accordance with ASTM C 1549. Thermal emittance values are determined in accordance with ASTM C 1371. SRI is calculated in accordance to ASTM E 1980 with medium wind speed. Panels are unwashed. The Sherwin-Williams company certifies these tests to be true and accurate and performed by their laboratory.
