Why is a white roof recommended in urban areas?
Buildings located in urban areas are more vulnerable to the effects of heat islands.
A white TPO membrane reflects a large portion of solar radiation, which helps reduce the roof temperature, improve the building’s energy efficiency, and extend the lifespan of the roofing system. In addition to providing excellent waterproofing, it is a sustainable solution well-suited to the demands of urban environments.
Designed to perform, season after season.
