Fly-Bys: Detailing of Extended Planar Elements in Curtain Wall

Many architects wish to express a planar quality in their façade designs. This expression results in wall assemblies that extend past the corner and appear to float over the building volume behind. While aesthetically exciting, this motif creates numerous challenges for control of heat, air and moisture. This presentation will explore several methods to maintain the design intent and deliver performance. Several case studies with both unitized and stick built systems will be presented. The presentation will focus on detailing, mockups, testing and construction.
