Pro Roofing NW, a leader in Energy Star Technology, about Owens Corning Duration Premium Cool Shingle
Duration Premium Cool Shingles with SureNail Technology (Energy Star Rated):
Duration Premium Cool Shingles are made to meet new standards. These are not your normal granules. They are specifically designed to reflect way more solar than traditional granules. Cool Roofs reduce energy by using shingles with solar-reflecting granules that keep roofs cooler than conventional singles. Cool Roofs result in lower carbon dioxide emissions and help reduce the urban and suburban heat island effect which, in turn, reduces smog.
How do Duration Premium Cool Shingles work?
Duration Premium Cool Shingles utilize a new, highly reflective granule technology that allows them to reflect the sun’s heat, thereby reducing the heat transferred into the structure below.
[The sun’s radiation hits the roof surface]
A small amount of heat is absorbed by the Solar Reflectance: A large fraction of
roof and transferred into the building below solar energy is reflected by the roof
Back into the atmosphere
What is Thermal Emittance? Thermal Emmitance is the relative ability of the earth’s surface to radiate absorbed heat. That’s why Duration Premium Shingles feature solar-reflecting granules that help keep roofs cool for a more comfortable living space below.
Saving energy has never looked, of felt better:
Utilizing a new, highly reflective granule technology that bounces back the sun’s rays, Duration Premium Cool Shingles help keep roofs cooler, resulting in a more comfortable living space below. In addition, Duration Premium Cool Shingles:
*Help lower energy bills by keeping the roof cooler-which also reduces wear and tear on the air conditioning system.
*Can reduce environmental impact. Less energy needed to cool a home means less energy consumption, decreasing CO2 emissions.
*Help extend the life of the roof. Thanks to solar-reflecting granules that reduce shingle temperature the subsequently slow asphalt aging.
*Are backed by a Lifetime Warranty (Preferred Contractor) and a 130 MPH wind resistance warranty.
*Algae Resistance Warranty is also included.
*Coordinate with color-matched Owens Corning DecoRidge Hip and Ridge for an extreme profile on the roofline.
*Meet 2009 California Title 24, Part 6, requirements which call for a Cool Roof or equivalent improvement.
*Rated by the Cool Roof Rating council (CRRC)
**Estimated roof surface temperatures reduce base on 1998 NIST study. Analytical Study of Residential Buildings with Reflective Roofs.: A temperature reduction is representative of a change from a typical roof to a Cool Roof (soar reflectance 10-25) in most climates.
