High Sri Grey Gray Roof

Berridge metal products have a high recycled content and are 100 recyclable at the end of their lifespan.

High sri grey gray roof.

Solar reflectivity r solar reflectance index sri by color. Relative ability of roof surface to emit release absorbed. Understanding how a construction material like metal roofing or siding will interact with the sun can help a building prepare for weather conditions minimize heating or cooling costs and reduce heat island effects in urban areas. There are 3 main figures to understand when choosing a color.

Recycled content of berridge metal. The sr value is a number from 0 to 1 0. Solar radiation heats the roof surface. Some heat that was absorbed by roof is transferred into the building.

Owens corning oakridge 32 8 sq ft estate gray laminated architectural roof shingles. Timberline hd reflector series plus shingles can be used to comply with 2016 title 24 part 6 cool roof requirements of the california code of regulations. Item 10097 model 1093059. Duration series shingles are unrivaled by any other architectural shingles because they feature our patented surenail technology a technological breakthrough in shingle design.

Timberline hd reflector series plus shingles are rated by. A value of 0 indicates that the material absorbs all solar energy and a value of 1 0 indicates total reflectance. The selection of materials with a high sri can reduce indirect solar gain in buildings and reduce the urban heat island effect. Even if not required by energy codes cool asphalt roofing shingles may lower the cooling load on a home in hot climates.

Solar reflectance thermal emittance and solar reflectance index sri. Ref cool roof rating council solar reflectance index calculation worksheet. Tsr e and sri values. Timberline hd reflector series plus shingles meet green building standards code of los angeles county for residential buildings.

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. This may increase your home s energy efficiency and help the environment. The sri value reflects how well a roof rejects solar heat.

Cambridge tm cool colors reflect a percentage of solar radiation. Sri can be calculated based on the pitch of a roof its weight its solar reflectance thermal emittance and its ageing characteristics. The series highlights our popular duration shingles along with up to 7 other duration styles depending on where you live that feature unique performance characteristics.
