How does Stick System Curtain Wall compare to unitized systems in cost and installation efficiency
When comparing stick systems to unitized curtain wall systems, cost and installation efficiency are determined by project scale, labor rates, site logistics, and program constraints. Stick systems generally have lower fabrication and transport costs because primary components are extruded profiles, gaskets, and ancillary items shipped in bundles rather than large pre-glazed panels. For projects with complex site access or limited crane availability, stick systems can be installed with smaller lifts and less gantry work, which reduces heavy-lift costs. However, on-site labor intensity is higher: glazing and sealing are performed at height, requiring skilled glaziers and quality control to achieve consistent seals—this increases labor hours and supervision needs. Unitized systems, by contrast, are factory-assembled and glazed into modules, delivering consistent quality, integrated thermal breaks, and faster on-site erection (often one crane pick per unit), which shortens the façade construction schedule. For high-rise or high-volume projects, unitized systems frequently yield lower overall installed cost due to reduced site labour and compressed installation timelines. In mid-rise or low-rise buildings with simple geometry and local labor availability, stick systems often present the most cost-effective option. Lifecycle costs must also be considered: initial savings with stick systems may be offset by increased long-term maintenance if on-site sealing quality varies. Ultimately, a detailed cost-benefit analysis that includes material, fabrication, transport, site labor, schedule impact, and warranty provisions is required to determine the most efficient choice for a specific project.
