The Solar Solution
KEMPERDUR® REFLECT makes roofs cool in more ways than one. KEMPERDUR® REFLECT is a solar reflective roof paint that is applied to flat roofs for optimal solar reflectance and the preservation of a sufficiently cool roof.
This solar reflective roofing solution from KEMPERDUR utilizes liquid synthetic materials with particular properties to effectively reflect UV and infra-red radiation ensuring that the surface temperature remains cooler than when using traditional roofing materials.
KEMPERDUR® REFLECT is a solvent-free, solar reflective paint for flat roofs. It can be installed quickly and easily to existing KEMPEROL® roofs and is suitable for overlaying bitumen roofs where the solar reflectance needs to be increased.
- With buildings that utilise air conditioning systems, Kemperdurs solar reflective roof paint can be applied to exterior surfaces which reduces energy consumption, saves costs and lowers the carbon footprint.
- The reflection of sunlight on roofs with some PV systems helps to improve the energy yield.
- Reflective surfaces minimize the heat island effect, helping to lower temperatures in built up and inner-city areas, providing an energy efficient cool roof solution
KEMPERDUR® Reflect is suitable for overlaying bitumen roofs where the solar reflectance needs to be increased.
Excellent SRI Values
Tests carried out at the Fraunhofer Institute show that the KEMPER SYSTEM product has an exceptional solar reflectance index (SRI) value.
In comparison to the SRI values achieved by KEMPERDUR® REFLECT, a black control substrate had an SRI value of 0, and a white reference surface achieved an SRI value of 100. The higher the value, the cooler the roof.
The degree of solar reflectance is roughly 87% for REFLECT. Referring to the amount of sunlight that is reflected by the roof.
KEMPER SYSTEM commissioned German technical inspection agency, TÜV, to document the cooling effect of various systems on roof surfaces. They observed a difference of 40% in favour of REFLECT when compared against bitumen substrates at an outdoor temperature of 22°C. A convincing result!
