Our solution: coating to reduce the building’s heating
As its name implies, a Cool Roof is a roof designed to reflect solar radiation. The point of a Cool Roof is to limit a building’s heat during the summer. This improves the occupiers’ comfort without resorting to air-conditioning, which is expensive and emits greenhouse gases.
That’s all very nice, but how does it work?

Temperature between 10 and 35°C (BaseCoat), between 15 and 35°C (TopCoat), relative humidity < 80%. Do not apply if rain forecast within 24h.
Surface
Perfectly clean and dry surface. Do not apply on zones where water often stagnates.
Do not spray on if wind speed is above 50 km/h.
Application times
Leave 24 hours to dry between each BaseCoat and TopCoat layers. Our teams apply 5,000 m² of Cool Roof over one week on a bitumen membrane roof with ideal weather conditions and a clean roof
