Curtain walls are an important element of modern building design. They are used to create a façade on a building that is designed to resist wind and rain, while also allowing natural light to enter the building. Curtain walls can be made from a variety of materials, and they come in a range of designs. In this article, we will explore the different types of curtain wall systems that are available today.
Curtain wall systems have become increasingly popular in modern building design, offering a range of benefits such as increased natural light, improved energy efficiency, and aesthetic appeal. A Curtain Wall System is an exterior wall system that does not carry any structural load but is designed to support its own weight and resist wind and seismic forces. This system typically consists of vertical mullions, horizontal transoms, and glass or opaque panels.
There are several types of curtain wall systems available, each with its own unique characteristics and advantages. The four most common types of curtain wall systems are stick-built, unitized, semi-unitized, and structural glazing.
Stick-built curtain wall systems are assembled on-site piece-by-piece, with mullions and transoms attached to the building frame. This type of system can be cost-effective and provide flexibility in design, but can be time-consuming to install and may require more on-site labor.
Unitized curtain wall systems are pre-fabricated off-site and installed as pre-assembled units onto the building frame. This system can be more expensive, but offers faster installation times and reduced on-site labor.
Semi-unitized curtain wall systems are a hybrid of stick-built and unitized systems, where larger panels are pre-assembled off-site and smaller panels are assembled on-site. This system offers a balance between cost and installation efficiency.
Structural glazing curtain wall systems use structural silicone to attach the curtain wall system to the building structure, eliminating the need for visible mullions and transoms. This system can provide maximum energy efficiency and aesthetic appeal, but may require more precise installation and be more expensive.
When selecting a curtain wall system, it is important to consider factors such as design flexibility, cost, energy efficiency, and installation time. Working with a qualified design professional can help ensure the best system is selected for the specific project needs.
