Curtain wall systems are classified into stick-built systems and unitized systems:
- Stick System: This traditional method involves assembling aluminum frames, glass panels, and other components on-site. It is cost-effective for smaller projects but requires more labor and installation time.
- Unitized System: In this method, pre-fabricated panels are manufactured in controlled environments and transported to the site for quick installation. This system ensures high precision, better quality control, and faster installation, making it ideal for high-rise buildings.
Both systems have their advantages, with stick systems offering flexibility in design modifications and unitized systems excelling in speed and performance.
