A unitized structural glazing system is a pre-assembled glazing system. Multiple glazing types and materials can be combined into one “unit” in a quality controlled shop environment. The glazing materials are siliconed in place and allowed to fully cure to give a similar flush exterior appearance to that of a stick-built system. After the glass, spandrel materials and anchors are glazed into unit frames within the shop, they are loaded onto flatbed trucks to be installed just in time at the job site. The units receive additional silicone/EPDM gaskets after they are installed in place by a crane from the outside, or from each floor to create the stack joint. The stack joint acts as the complete air and moisture barrier of the system allowing a weep at each floor. Unitized systems handle movement much better than most others because each panel is gasketed together to be able to move independently with the structure, and the additional movement capacity of the anchors. Generally, these systems are used on mid-rise to high-rise structures that are 20,000 sq. ft. and above where there is a higher frequency of repetition, tight job site access, and high installation labor costs.
