Curtain walls are thin walls, usually aluminum frames. It contains fillers of glass, sheet metal or thin stone. The frame is connected to the building structure and does not carry the floor or roof load of the building. Wind and gravity loads on curtain walls are usually transferred to the building structure at the floor line. The history of the aluminum frame wall system dates back to the 1930s. It developed after World War II. When there was a large supply of aluminum available for non-military purposes.

Curtain wall systems range from a manufacturer's standard catalog system to specialized custom walls. As wall area increases, the cost competition between custom wall and standard systems becomes more and more intense.


The following is a brief description of common curtain wall frame methods and components.

Curtain walls can be divided into the following categories by their manufacturing and installation methods: pole systems and unitized (also known as modular) systems. In the stick system, curtain wall frames (mullions) and glass or opaque panels are installed and connected piece by piece. In a modular system, the curtain wall consists of large units that are assembled and glazed at the factory. It was then transported to the site and erected on the building. The vertical and horizontal mullions of the modules fit together with adjacent modules. Modules are usually constructed as one layer high and one layer wide, but can contain many modules. Typical units are five to six feet wide.

Both modular and rod-shaped systems are designed as internal or external glass systems. Internal and external glass systems have different advantages and disadvantages. The internal glass system allows glass or opaque panels to be installed into the curtain wall openings from inside the building. No details were provided about the internal glass system because air penetration is a concern for the internal glass system. Internal glass systems are often specified for applications with limited internal obstacles. To allow full access to the interior of the curtain wall. For low-rise buildings with easy access to buildings, exterior glass is usually specified. For high-rise buildings. It is sometimes necessary to replace the glass due to the need to replace the glass from the rear window. Thus, internal glass is sometimes used.

In an external glass system, glass and opaque panels are installed from the outside of the curtain wall. The external glass system requires the swing table or scaffolding to be repaired or replaced on the outside of the curtain wall. Some curtain wall systems can be glazed from the inside or outside.

Typical opaque panels include opaque arched glass, metal panels, thin stone, and other materials, such as terracotta warriors or FRP (fiber-reinforced plastic).

Visual glass is hollow glass, which can be laminated with one or two pumice. Usually fixed, but sometimes glaze into operable window frames. And integrated into the curtain wall frame.

Artificial glass can be monolithic glass, laminated glass or insulating glass. Opaque glass pallets can be made opaque by using a sunscreen (film / paint or ceramic frit) on an unexposed surface or by a "shadow box" structure. This makes the opaque glass tray glass opaque. The structure of the shadow box creates a sense of depth behind the span glass that is sometimes required.

The metal plate can take various forms. Including aluminum, stainless steel or other non-corrosive metals. A composite board composed of two thin aluminum plates sandwiched by a thin plastic sandwich. Or a sheet of metal (with or without an inner layer) composed of metal sheets bonded to a rigid insulating layer to create a sandwich panel.

The most common thin stone slabs are granite. White marble should not be used because it is deformed by hysteresis.

Curtain walls often form part of a building's wall system. For a successful installation, careful integration with adjacent elements is required.
