Roof Shingle With Solar Reflectance

These are all manufactured by certainteed.

Roof shingle with solar reflectance.

Residential and commercial roofing shingles slate roof ventilation roof underlayments asphaltic and tpo roof membranes. Cambridge tm cool colors reflect a percentage of solar radiation. Buy cool asphalt shingles which use specially coated granules that provide better solar reflectance. Shingle roofs consist of overlapping panels made from a variety of materials such as fiberglass asphalt wood polymers or metals.

Every shingle in the cool roof collection features a precise mix of solar reflecting granules to help comply with the solar reflectance index sri requirements of title 24 part 6 even with deeper vibrant colors. Feature gaf proprietary color blends and enhanced shadow effect for a genuine wood shake look. The highly solar reflective shingles with up to 40 solar reflectivity are landmark solaris platinum shingles. Roofing shingles and materials plus factory certified roofers including ratings from real homeowners from north america s largest roofing manufacturer.

Coating existing asphalt shingles to make them cool however is not normally recommended or approved by shingle manufacturers. Sri measures the roof s ability to reject solar heat defined such that a standard black reflectance 0 05 emittance 0 90 is 0 and a standard white reflectance 0 80 emittance 0 90 is 100. Solar radiation heats the roof surface. It also must meet the specific solar reflectance thermal emittance and or solar reflectance index values defined by the specific energy code.

Incorporates both solar reflectance and thermal emissivity in a single value. The attic under the roof. For an asphalt roofing shingle to be classified as a cool under the energy codes it needs to have a cool roof rating council crrc rating for thermal emittance and solar reflectance. How they can be made cool.

The solar reflective shingles with 20 or less solar reflectivity that ross saw are landmark and landmark pro solaris shingles. Solar reflective shingles are designed specifically to reduce the absorption of the suns infrared radiation by reflecting ir rays off the surface of the roof thus not allowing the heat to be transferred to the interior of the structure i e. Some heat that was absorbed by roof is transferred into the building. Explore our expanded cool roof collection and reflect your unique style.

The cool roof rating council was created in 1998 to develop accurate and credible methods for evaluating and labeling the solar reflectance and thermal emittance radiative properties of roofing products and to disseminate the information to all interested parties. The sri value reflects how well a roof rejects solar heat.
