The great pyramids
The daylighting system at Duo-Gard Industries' headquarters in Canton, Mich., is dominated by two pyramid skylights that flood the 20,000-sq.-ft. building with enough diffused daylight to eliminate the need for electric lights. Manufactured of translucent polycarbonate structured sheet in extruded aluminum framing, the 20-by-20-ft. skylights have 200 times the impact strength of glass.
