Climate change represents well-known dangers and risks. Its effects are even more harmful in cities due to heat islands, combined with pollutants and greenhouse gas (GHG) emissions. The increase in air temperature in our buildings and our cities affects indoor and outdoor comfort, our health, and our energy costs. The colour white plays a significant role when it comes to the longevity of the roof because it prevents the waterproofing membrane from overheating when exposed to the sun, therefore reducing the urban heat island effect.
Indeed, due to the reflectivity and emissivity properties of the materials used, cool roofs are a solution that reflects solar heat and mitigates its absorption by reflecting solar radiation back to the atmosphere.
Moreover, the SOPREMA SENTINEL line of PVC membranes is an excellent single-ply solution to help counter urban heat islands by reducing the surface temperature of roofs.
