STRUCTURAL GLASS FACADES - USC School of Architecture

Glass System Interface: The interface
generally takes the form of a hole or slot
in the side rails of the panel attaching to
an offset plate or component tying back
to the structural support system.
Glass type: This strategy supports the
use of conventional glass fabrication.

Resources and Technology
Materials and Processes: Glass fabrication is conventional. Attachment components are
typically simple steel plate assemblies tying back to the backer structure.
Material Suppliers and Subcontractors: The structural glazing must be done by a qualified
glazier in strict compliance with the sealant manufacturer’s requirements. Adhesion testing is
also required.
Durability and Maintenance: Durability will be a function of the materials used, the adequacy
of the finish materials, and the quality of their application. This system provides for a buttglazed
silicone seal, which has proven to provide a durable weather seal.
Structural Performance
Spanning capacity: The spanning capacity is picked up by the rails. It is even conceivable to
use a heavier rail system that would provide for the glazing of multiple glass panels, as with
the unitized systems.
Typical deflection criteria: The glass can be provided perimeter support as required to
control deflections.
