Cool Zone® - Cool Roofing System
In the commercial roofing industry, reflectivity and cool roofing has been the dominant discussion point for several years, and the Duro-Last® Cool Zone® roofing system has set the standard for single-ply roof reflectivity and the resulting energy savings. Now, terms like sustainability, cool roofs, and cool roofing are receiving a lot of attention, and once again, Duro-Last® is setting the bar. But what does sustainability and cool roofing really mean for building owners, facility managers, contractors, architects, and other specifiers? It means that the design, construction, maintenance, life-cycle impact, adaptive re-use, destruction, and recycling of roofing components must help meet the long-term environmental standards demanded by today's high-performance buildings.
To be considered "sustainable," a roofing system must meet the Five E's of high-performance roofing: Energy, Environment, Endurance, Economics, and Engineering. In each of these areas, the Duro-Last® Cool Zone cool roofing system leads the commercial roofing industry.
