The size of the unitized curtain walls are dependent on the floor to floor height of the building.

A curtain wall is defined as thin usually aluminum framed wall containing in fills of glass metal panels or thin stone.
Since the curtain wall is non structural it can be made of lightweight materials thereby reducing construction costs.
Hence it is essential to keep in mind the mode of transportation and installation while planning the depth of facade.
A curtain wall system is an outer covering of a building in which the outer walls are non structural utilized only to keep the weather out and the occupants in.
Unitised curtain walling can be installed either from the interior of the building using a beam on the floor above or from the outside using a crane.
Curtain wall systems are structurally capable of spanning multiple floors.
Curtain walls generally fall into two basic categories that are based on their method of fabrication and installation.
They can offer a continuous glazed façade covering the full height of the building.
The installation team must be safely connected to the structure via a harness.
The author worked in construction industry for 5 years and working in façade.
When glass is used as the curtain wall an advantage is that natural light can penetrate deeper within the building.

The framing is attached to the building structure and does not carry the floor or roof loads of the building.
These are unitized or modular systems figure 9 2a b and stick systems figure 9 3a b in the stick system the curtain wall frame mullions and glazing panels are installed and connected together piece by piece.
Curtain wall system technology has developed over the years into a proliferation of highly engineered design.
