Fundamentals of Curtain Walling

Defining Curtain Wall Systems

Curtain wall systems are non-structural cladding systems for the external walls of buildings. They are designed to resist air and water infiltration, sway induced by wind, and seismic forces. These systems are made of lightweight materials such as aluminium and glass, enhancing the aesthetic appeal of a building.

Curtain walls are typically installed from the outside of a building using cranes and are independent of the building structure. The design and installation of these systems require meticulous planning to ensure proper integration with the building’s architecture and functionality. Curtain wall systems offer architects flexibility in design and allow for natural light to penetrate deeper into the building, creating a visually open and spacious interior.

Components of a Curtain Wall

The basic components of a curtain wall include glass panels, mullions (vertical members), transoms (horizontal members), gaskets, and spandrel panels. These elements work together to create a continuous, lightweight facade that provides weather resistance and thermal insulation. The glass panels are held in place by the mullions and transoms, which are supported by the building structure.

Moreover, gaskets are used to seal the joints between glass panels and metal frames, preventing water infiltration and ensuring the system’s performance under different weather conditions. Spandrel panels are located between the vision glass and conceal the floor slabs, enhancing the overall appearance of the curtain wall. The precise coordination of these components is crucial to achieving a functional and visually appealing curtain wall system.

For additional information on the components of a curtain wall system, it is important to consider the role of pressure plates and caps in securing the glass panels within the system. These components play a vital role in maintaining the structural integrity of the curtain wall and ensuring its longevity. Understanding the intricacies of each element is essential for architects, engineers, and builders involved in the design and implementation of curtain wall systems.
