There are several different types of curtain walls that can be used in building construction, each with its own unique set of characteristics and advantages. The appropriate type of curtain wall for a project will depend on the specific requirements and design of the building, as well as the budget and other factors.

One of the most common types of curtain walls is the unitized curtain wall, which is made up of large panels that are pre-assembled in a factory and shipped to the site for installation. Unitized curtain walls are typically made of aluminum or other lightweight materials and are attached to the building using bolts or other fasteners. They offer a number of advantages over other types of curtain walls, including improved energy efficiency, enhanced structural integrity, and faster installation times. However, they are also typically more expensive to install than other types of curtain walls and may not be as flexible in terms of customization.

Another type of curtain wall is the stick-framed curtain wall, which is assembled on site using individual pieces of framing material, such as aluminum or steel, that are cut to size and connected using fasteners such as screws or bolts. Stick-framed curtain walls are a cost-effective option that can be easily customized to meet the specific requirements of a project. They are also relatively easy to install and maintain, making them a popular choice for many building projects.

In addition to these two main types of curtain walls, there are also several specialized types of curtain walls that are designed to meet specific performance or aesthetic requirements. These include:

  • Structural silicone glazed (SSG) curtain walls: These are similar to unitized curtain walls, but the glass is attached to the frame using structural silicone instead of fasteners. This can provide improved thermal performance and weather resistance.
  • Point-supported curtain walls: These are curtain walls that are supported by a series of vertical supports, rather than being attached to the building’s.
