What are the two types of curtain wall systems?

Curtain wall systems are classified into stick-built systems and ʻōnaehana hui pū :

• 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 ʻōnaehana lāʻau offering flexibility in design modifications and ʻōnaehana hui pū excelling in speed and performance.
