Unitized curtain systems are composed of large glass units that are created and glazed within a factory and then sent to the construction site. Once on site, the units can then be hoisted onto anchors connected to the building. High quality, due to tight tolerances of fabrication in a climate-controlled environment, is only one hallmark of this type of system. Since there is no on-site glazing, another major benefit of using a unitized system is the speed of installation.
