Glass curtain Wall

The differences between stick and unitized or “modular” glass curtain wall systems:

Fabrication and installation methods classify glass curtain walls into two general categories: stick systems and unitized or modular systems. Stick systems, utilize a frame made up of millions and glass or opaque panels. These panels are designed and installed as a unitized system.

Unitized systems are composed of large units that are assembled and glazed in the factory. The installer or builder then receives and erects the glass sections on the building site. Each vertical and horizontal mullion in each module mates together with adjoining modules. Typical units are five to six feet wide, while modules range in dimension. The standard size is around one story tall and one module wide; however each section may incorporate multiple modules.
