Cool roofing involves applying light-colored, highly reflective coatings to rooftops that bounce back a large portion of solar radiation. Our reflective coating significantly lowers the surface temperature of a flat roofing membrane: in full sunlight, it can reach up to 80 °C, but with our solution it is practically cut in half to around 40 °C. In hot weather, this reduction in roof temperature translates into a 5 °C to 10 °C decrease inside the building, reducing the need for air conditioning, saving energy, and extending the lifespan of the roof. Real-life example: Outdoor temperature in the shade: 25 °C Temperature of a roofing membrane in direct sun: ~70 °C Temperature with our coating: ~35 °C Estimated indoor cooling during hot periods: 6 °C to 7 °C It’s a simple, durable, and effective solution that improves thermal comfort, reduces energy consumption, and supports the energy transition.

Cool roofing provides several concrete benefits for the energy transition: Lower electricity consumption – by reducing indoor temperatures, it limits the need for air conditioning, especially during summer peaks. Reduced greenhouse gas emissions – less cooling means less energy production, often from fossil fuels. Longer roof lifespan – the coating protects against UV rays and thermal shocks, reducing renovation needs and the carbon footprint of materials. Mitigation of urban heat islands – by reflecting heat, it helps cool the surrounding air, which can lower overall energy demand in cities. In short, it’s a passive solution that supports both energy efficiency and climate adaptation.
