Architectural Façade Panel and Window Glazing

The glass, glazing, curtain-wall systems interface with the SlenderWall system in a similar fashion as with the 6-inch-thick architectural precast concrete systems. The most economical design is a flush-faced design where the window system is in alignment with the exterior face of the SlenderWall system (see Drawing A-2 in the Typical Details). This allows the window frame to overlap the 2-inch-thick SlenderWall precast. An optional upgrade allows glazing to be set back from the face of the SlenderWall precast (see Drawing A-2 in the Typical Details). A precast return is introduced to produce the desired set-back. The maximum standard return is 4-½-inches from the face of the panel. Wood blocking is then field-applied to frame around the window opening to support the glazing system.

It is important to note that the weight of the glazing system cannot bear on the precast in the system. All glazing loads must be transferred onto the steel-stud back-up frame. Refer to Drawing Detail A-2 in the Typical Details for details of the window head, jambs, and sill.
