A semi-unitized curtain wall is a type of building façade system that combines characteristics of both unitized and stick-built curtain walls. It is a popular choice for modern high-rise buildings and provides several advantages in terms of construction efficiency and performance.
In a semi-unitized curtain wall system, the building envelope is divided into pre-fabricated units, but not every component is fully assembled off-site like in a unitized system. Instead, the framework and structure of the curtain wall are typically fabricated in a factory, while the infill panels, such as glass or metal panels, are installed on-site.
The semi-unitized system offers a balance between the benefits of unitized and stick-built curtain walls. It allows for faster installation compared to traditional stick-built systems because a significant portion of the assembly work is done off-site. The pre-fabricated units can be transported to the construction site and easily installed, reducing on-site labor and construction time.
Furthermore, the semi-unitized system provides better quality control during the manufacturing process, as the framework is fabricated in a controlled environment. This helps ensure higher precision and consistency in the assembly, resulting in a more reliable and durable curtain wall system.
However, it’s important to note that the specific characteristics and construction methods of semi-unitized curtain walls can vary depending on the manufacturer and project requirements. Architects, engineers, and construction professionals typically consider factors such as building design, location, wind loads, thermal performance, and aesthetics when selecting a curtain wall system.
