Glass Curtain Wall

Glass Curtain Wall


A curtain wall is a non-structural exterior covering of a building. A glass curtain wall is a lightweight aluminum framed exterior wall equipped with glass or metal panels, which can be made of lightweight aluminum and help reduce construction costs.

Generally, glazed curtain walls are attached to the outside of the floor slab. The aluminum facade is usually part of the wall system that makes up the wall. Each glazing system needs to be integrated with other adjacent wall cladding, roof, or wall details.

Fabrication and installation methods divide aluminum glazed curtain walls into two broad categories: rod systems and unitized or modular systems. 
Rod-built curtain walls: frames consisting of multiple glass or opaque panels are sent directly to the site for assembly and installation.
Unitized Curtain Wall System: Panelled curtain walls consist of prefabricated units built in a controlled shop environment. These unitized curtain walls are sent to the site ready to be fixed to the floor slab. Aluminum curtain walls are received and installed on the building site by the installer.


Aluminum glass curtain wall systems range from standard prefabricated systems to specialized custom wall units. Increased costs are usually accompanied by additional customization and larger sizes.
