There are mostly 2 types of Curtain Wall installations; Unitised and Stick Systems.
Unitised Curtain Wall Systems
Unitised Systems are factory-manufactured modules that are installed on-site using an interlocking design. The glazing of the visual and spandrel panels is completed in the factory before shipping to the site.
Stick Curtain Wall Systems
Stick Systems get its name from the fact that the mullions are the first component installed on-site.
Most of the manufacturing and assembly of the Curtain wall takes place on-site. Up to 70% of the work is done on-site.
After the mullions are installed the transoms are fixed into position followed by the gaskets, glazing materials and vents (when required). All these components are secured onto the grid using pressure plates and cover caps.
