Curtain Wall Systems

Curtain wall systems are non-structural, external cladding systems for buildings, typically seen on large, multi-story structures. They act as a barrier between the interior and exterior of a building, supporting only their own weight and loads from wind and seismic forces, which are then transferred back to the building’s primary structure. This distinguishes them from traditional walls, which form part of the building’s structural framework. 

Key components

Frame: Usually made of lightweight, durable, and corrosion-resistant materials like aluminum or steel.

Infill panels: These can be glass, metal, stone, terracotta, fiber-reinforced plastic (FRP) or louvres. Often, they are composite panels with facing materials bonded to an insulated core. 

Structural Glazing Systems: These systems attach the glass directly to the frame using structural sealant, creating a seamless, all-glass appearance, 

Unitized Systems: Prefabricated in large modules off-site and then transported and installed as panels. This method is faster and more efficient, particularly for tall buildings, as it reduces on-site labor and allows for higher quality control in a controlled factory environment
