Reflective Roof Coating Energy Savings

Savings are important for both old and new levels of insulation.

Reflective roof coating energy savings.

A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning. The most effective energy saving finish for metal roofing is commonly referred to as cool metal roofing. Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. If not your energy savings from applying a reflective roof coating could range anywhere from 20 to 70 when it s all said and done.

1 cool your roof cool roofs are lighter in color than traditional black asphalt or dark wood shingles and save energy by reflecting light and heat away rather than absorbing them. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. To learn more about our products visit the western colloid website. This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof.

For anyone who may not know a reflective roof coating saves energy in your building by reflective uv rays back into the atmosphere. This highly reflective coating uses cool pigments in the paint to increase solar reflectance and lower the surface temperature of the roof. Surface solar reflectivity is measured using a precision spectral pyranometer with the device alternately faced. Reflectivity or albedo is the hemispherical reflectivity integrated over a particular wavelength band of the.

This means in the summer you have to run your ac more to heat the building just because the sun is shining. The total value of base plus peak energy savings offered by a reflective roof is significant averaging more than 1000 annually in most climate zones for a typical commercial building. However if you live in a hot climate that experiences warm temperatures and sunny days for a substantial portion of the year you can expect energy savings of up to 70. Saving energy with reflective roof coatings 1.

Please remember the energy savings that can be achieved with reflective roofing is highly dependent on facility design insulation used climatic conditions building location and building envelope efficiency. All these coatings meet the energy star guidelines for energy efficiency and savings. When the right reflective coating is applied building owners can enjoy significant energy savings and increased longevity of their roof system.
