What common installation challenges occur with Curtain Wall systems and how to avoid them

Common installation challenges for curtain walls include tolerance misalignment, water infiltration, logistics and sequencing conflicts—each avoidable with disciplined planning and quality control. Tolerance issues arise when as-built slab edges differ from design tolerances; mitigate by conducting detailed site surveys and full-scale mock-ups, and by specifying adjustable brackets and shims within anchor zones. Water infiltration often stems from blocked drainage, insufficient slope, or incomplete air/water barrier integration; use tested drainage designs, factory-applied gaskets, and verify slope and weep paths during installation. Logistics challenges—transport of large unitized panels, cranage limits and laydown space—are resolved by early logistics planning, delivering in manageable panel sizes and sequencing deliveries to match site capacity. Sequencing conflicts occur when other trades (curtain wall vs. MEP, insulation, roofing) are not coordinated; implement a façade installation plan integrated into the master schedule, with clear interfaces and responsibility matrices. Mock-ups are a cost-effective risk reduction tool—perform water-tightness and air infiltration testing on representative mock-ups before mass installation. Use experienced façade installers and require supplier supervision during critical phases to ensure sealant and gasket installation meets manufacturer’s instructions. Finally, maintain a spare parts inventory for custom extrusions and glass to avoid delays during repairs. Proactive coordination, realistic tolerances and field testing prevent typical issues.
