The
pursuit of elegant building enclosure design is ever-growing,
particularly for aluminum-framed curtainwall systems. Where these
curtainwall systems transition to horizontal roof systems, designers
have long sought to minimize the visual impact of these conditions by
subtly concealing them. One approach to conceal these transitions from
wall to roof is by continuing the curtainwall above the roof line to
form a transparent parapet, often referred to as a “fly-by” curtainwall
parapet or a “fly-by” parapet (Photo 1).
