Green and Eco

Most green roof surfaces stay cooler than conventional rooftops under summertime conditions leading to less heat transfer to the air above the roof helping to keep urban air temperatures lower as well.

Energy efficiency

Roofing materials with high solar reflective value can lower roof surface temperature, decrease the amount of heat transferred into a building and significantly reduce air conditioning costs.
