What installation challenges must contractors consider when assembling a structural glazing facade on site?

Structural glazing façade installation requires meticulous preparation, skilled labor, and controlled site conditions. Contractors must ensure proper surface preparation, including cleaning, priming, and compatibility testing of the frame materials with structural silicone. Sealant application requires precise control of joint thickness, typically 6–12 mm, to ensure adequate strength. Environmental factors such as dust, humidity, temperature, and wind must be controlled, as poor conditions can compromise adhesive curing. Contractors must use calibrated tooling equipment for silicone application to ensure uniform bonding. Glass alignment must meet tight tolerances, often ±2 mm, requiring laser leveling and accurate jig systems. Furthermore, logistics planning is crucial; glass must be stored safely, protected from environmental exposure, and lifted with proper rigging. Installation sequencing must account for curing time and ensure that panels are not subjected to early loads. In high-rise settings, coordination with crane operators and BMU systems is essential.
