Choosing the right system depends on project scale, schedule and site conditions.
| Criteria | Stick System | Unitized System |
|---|---|---|
| Installation method | Frame and glass installed directly on site, mullion by transom in sequence. | Curtain wall modules fabricated and glazed off-site, then delivered and installed as complete units. |
| Construction speed | Suited to mid-scale buildings with flexible schedules. | Faster on-site erection — suited to high-rise projects on tight schedules. |
| Quality control | Dependent on site installation conditions. | Better quality control through factory fabrication. |
| Capital cost | Lower upfront investment. | Higher investment, suited to large-scale projects. |
| Best suited for | Low- to mid-rise buildings, renovations, localised sections. | High-rise towers, large office and hospitality developments. |
