BEC-Philadelphia welcomes architects, engineers, contractors, consultants, building owners and facility managers to attend our next monthly presentation. David Altenhofen, AIA, The Facade Group, will be making the presentation about the enclosure issues associated with extensions on curtainwall systems. Kindly join us for this free lunch presentation which is generously sponsored by The Architectural Glass Institute.
Abstract:
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.
Learning Objectives:
1. Identify the potential enclosure problems inherent with a fly-by including thermal bridging, air infiltration, water leaks, and condensation.
2. Understand the principles behind the various methods of structural support of a fly-by, either concealed in the curtain wall, independently separated, or a blended solution.
3. Analyze details for fly-bys from DD/construction documentation phase through shop drawings and construction.
4. Compare the pros and cons of fly-bys constructed with unitized curtain wall versus those constructed with stick-built curtainwall and understand the detailing differences.
