Design Span hp standing seam from AEP Span is the architect's choice for energy-efficient roofing, as seen on the project above. Its ‘Cool Roof' option “provides for high reflectivity and high emissivity,” in turn reducing “heat gain and heat island effects,” Vandervort says. The 22-gauge or 24-gauge roofing is made from up to 30 percent recycled content in widths of 12, 17, and 24 inches. A factory-applied butyl sealant comes standard, and a snap-together feature makes field seaming unnecessary. AEP Span, 800.733.4955;
