Bretz hashem akbari lawrence berkeley national laboratory berkeley ca 94720 usa abstract cooling energy savings of 10 to 70 have been achieved by applying high albedo coatings to residential buildings in california and florida.
High albedo roof membrane.
The topside of soprastar flam is protected by a white reflective embossed surface and the underside is covered by a thermofusible film.
And canada help keep good roofs and good buildings good for our customers through renovation restoration and maintenance as well as through new construction.
This membrane is designed for cool roof applications.
Reformulate or coat black membranes to make them reflective.
Ooling energy savings of 10 to 70 have been achieved by applying high albedo coatings to residential buildings in california and florida.
High albedo white and cool roofing membranes are recognized as a fundamental strategy that dense urban areas can deploy on a large scale at low cost to mitigate the urban heat island effect.
Reflective surfaces can deliver high solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the surface and high thermal emittance the ability to radiate absorbed or non reflected solar energy.
Since dirt accumulation can alter the performance of high albedo roofs as an energy efficiency measure we examined some high albedo coatings at various stages of exposure to determine the magnitude of this effect.
The most well known type of reflective surface is the cool roof.
Thermoplastic polyolefin tpo single ply roofing membranes are among the fastest growing commercial roofing products and have gained praise across the industry for their many performance and installation advantages.

Reflective surfaces are a form of geoengineering.
Soprastar flam resists pollution but also extreme weather conditions including temperatures ranging from 20 c to 100 c at very low temperatures soprastar flam remains flexible.
As demand increases for heat reflective and energy efficient roofing systems you can rely on tpo single ply roofing membranes to.
Most experienced field organization excellent customer satisfaction.
As one would expect albedo roofs are formulated with special high eminence materials that keep project a high level of thermal energy back into the atmosphere.

Built up roofs consist of a base sheet fabric reinforcement layers and usually a dark protective.
Choosing a high albedo epdm membrane roof instead of a conventional black epdm roof.
Single ply membranes are pre fabricated sheets rolled onto the roof and attached with mechanical fasteners adhered with chemical adhesives or held in place with ballast gravel stones or pavers.
How they can be made cool.
