EIA’s most recent data reports that energy-efficient, multi-paned windows are featured in 60 percent of U.S. buildings, which account for 75 percent of commercial floorspace. This presents a significant opportunity to improve existing buildings and to construct new buildings with energy-efficient daylight openings, including polycarbonate glazing and wall systems.

The parapet is so much more than the intersection of roof and wall. It’s also the junction where building aesthetics meets structural performance, air and moisture management, energy efficiency, construction trade sequencing and operational maintenance.
