Curtain Wall

Types of Curtain Wall Systems

Curtain wall is an non-structural glass and aluminum system that covers the exterior of low to mid-rise buildings. Curtain walls allows for better light penetration within the building as well as adds to the architectural design and look of the building.


  • Stick Curtain Wall Systems

    Stick systems consist of the curtain wall frame verticals (mullions) and glass or opaque panels that are installed and connected piece by piece. These parts are usually fabricated and shipped KD (knocked down) to the job site for installation. In stick-framed aluminum curtain walls, vertical mullions typically run past two floors, with a combined gravity/lateral anchor on one floor (wind load anchor), and another lateral anchor (dead load anchor) on the other.

  • Ladder Curtain Wall Systems

    Very similar to a stick system, a ladder system has mullions which can be split and then either snapped or screwed together consisting of a half box and plate. This allows sections of curtain wall to be fabricated in a shop, effectively reducing the time spent installing the system on site. The drawbacks of using such a system is reduced structural performance and visible joint lines down the length of each mullion.

  • Unitized Curtain Wall System

    Unitized curtain walls entail factory fabrication and assembly of panels and may include factory glazing. These completed units are installed on the building structure to form the building enclosure. Unitized curtain wall has the advantages of: speed; lower field installation costs; and quality control within an interior climate-controlled environment. The economic benefits are typically realized on large projects or in areas of high field labor rates.
