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?
