SopraStar

Reducing urban warming by using solar reflective cool roof membrane

Identification

SopraStar is a covering for flat roofs that limits the absorption of solar energy and which reduces both urban heat islands and summer discomfort in buildings . The surfaces of the building’s envelope (roofs and facades) can contribute to urban cooling.

Thanks to their radiative properties (solar reflectivity and thermal emissivity), Cool Roof systems do not absorb solar energy but reflect it. These systems allow the temperature of surfaces exposed to solar radiation to be reduced. Thanks to an SRI (Solar Reflectance Index) of 96, the SOPREMA Cool Roof membrane SopraStar allow a reduction of the impact of a building on urban warming of over 50%, whilst at the same time reducing the interior temperature of the building by 1 to 2°C (summer comfort).

Label Date November 2018
From France
Maturity stage Medium and large scale commercialization
Looking For Being supported toward bodies, organisations, governments, the European Union.
