What is meant by the term 'unitized curtain wall' in reference to building facades?

A unitized curtain wall system is a prefabricated panel that is assembled off-site and delivered to the construction site as a complete unit. These units typically consist of glass, aluminum, or other materials held together by a framing system. They are designed to fit together seamlessly, creating a continuous, unbroken appearance on the building facade. Unitized curtain wall systems offer a number of benefits, including faster installation times, higher quality control, and reduced on-site labor costs.
