Curtain walling

• The name, derives from the idea that the wall is thin and “hangs” like a curtain
• A non-load bearing exterior skin
• Does not contribute to the structural support of the building
• supports no load other than its own weight and the environmental forces which act upon it

Types of Curtain Walling

• Stick System
• Unitized System
• Face Cap System
• Structural sealant Glazing System (SG)
• Point Fixing System
• Slope Glazing or Roof Glazing (Sky Light)

Stick system

• Components selected to meet requirements of project,
• Framing members delivered to site as pre-cut and machined sections,
• Frames fixed to floor slab/structure,
• Opaque and transparent infills glazed-in.

Advantages of Unitized Systems

• High quality, due to tight tolerances of fabrication,
• Factory assembled, providing
• enhanced quality control
• Less dependence on site installation,
• Less site labor costs,
• Curtain wall installation during construction,
• No need to Climber and Scaffolding,
• Movement in all three Axes,
• Site workshop not required,
• Site storage may not required.

Structural sealant glazing systems

• Glass bonded to frame Or interior Glass using structural sealant,
• Used as part of stick or unitized wall,
• Glass deadweight usually transferred by mechanical means,
• Live loads on glass transferred through sealant,
• Used in vertical or sloping situations.
