A stick curtain wall is a type of facade system where the components (mullions, transoms, glass panels, and other elements) are fabricated and assembled on-site rather than being pre-assembled in a factory. This system is commonly used in mid- to high-rise buildings due to its flexibility in design and adaptability to complex building structures. To improve thermal performance and reduce heat transfer, thermal breaks are often incorporated into the aluminum mullions. These insulating materials help to minimize energy loss and enhance the overall energy efficiency of the building

Components of a Stick Curtain Wall System

• Mullions (Vertical Members) – Provide structural support and transfer loads to the building structure.
• Transoms (Horizontal Members) – Connect the mullions and support the glass panels.
• Glass Panels – Typically double-glazed or laminated for insulation and strength.
• Brackets & Anchors – Secure the curtain wall system to the building structure.
• Gaskets & Sealants – Ensure waterproofing and airtightness.
• Thermal Breaks – Improve energy efficiency by reducing heat transfer.
