New insulation delivers peak savings.
Reflective roof energy savings.
Differences in the level of new versus old insulation appear to have a significant.
Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles.
Other brands of solar reflective paints as well energy saving asphalt shingles are priced similarly to traditional paints and 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.
Metal roofing is one of the most effective cooling materials but it is more expensive for materials and installation than asphalt shingles.
Saving energy with reflective roof coatings 1.
Surface solar reflectivity is measured using a precision spectral pyranometer with the device alternately faced.
For anyone who may not know a reflective roof coating saves energy in your building by reflective uv rays back into the atmosphere.
Most roofing systems absorb uv rays and that heat is transferred into the building.
This means in the summer you have to run your ac more to heat the building just because the sun is shining.
Reflectivity or albedo is the hemispherical reflectivity integrated over a particular wavelength band of the.
Standard or dark roofs can reach temperatures of 150 f or more in the summer sun.
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.
Tile roofs are also fairly more expensive than asphalt shingles.
