Reflective Roof Coating Energy Savings

Surface solar reflectivity is measured using a precision spectral pyranometer with the device alternately faced.

Reflective roof coating energy savings.

Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. To learn more about our products visit the western colloid website. Apoc cool roof restoration systems deliver high solar reflectivity and thermal emittance which significantly reduce roof temperatures. Most roofing systems absorb uv rays and that heat is transferred into the building.

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. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. Reflectivity or albedo is the hemispherical reflectivity integrated over a particular wavelength band of the. This highly reflective coating uses cool pigments in the paint to increase solar reflectance and lower the surface temperature of the roof.

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. 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. Lower roof temperatures have been proven to decrease internal building temperatures resulting in recurring savings from reduced air conditioning needs.

This means in the summer you have to run your ac more to heat the building just because the sun is shining. A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning. Savings are important for both old and new levels of insulation. 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.

The most effective energy saving finish for metal roofing is commonly referred to as cool metal roofing. Saving energy with reflective roof coatings 1. 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.
