Curtain Wall Systems

In general, he curtain wall systems can be classified in according to their method of installation:
1. Stick system
2. Unit system
3. Unit and mullion system
4. Column cover and spandrel system

Stick System

In the system, the wall is installed piece by piece. THe mullion members are installed first, followed by the transoms, the panels, and then the glazing or window units. The stick system was used extensively in the early years of metal curtain wall development, and is still in wide use.

Unit System

The wall is composed entirely of large framed units pre-assembled at the factory. The vertical edges of the units join to form mullion members, top and bottom members join to form horizontal rails.

Unit and Mullion System

The wall system is a compromise between the stick and unit system. First, the mullion mmebers are installed separately, then pre-assembled framed units are placed between them.

Column Cover and Spandrel System

In the system, the column cover is installed first which may be one or two stories in height, then the long spandrel panels which span between the column cover are placed between them. Finally, the galzig infils are fixed with the frame.
