Curtain Wall Installation:
A Comprehensive Guide

What is the purpose of a curtain wall?

Aluminum curtain walls, often used in commercial applications, serve several key functions. They provide protection from external elements like wind, rain, and temperature changes while maximizing natural light entry for a well-lit interior. Additionally, they enhance architectural aesthetics and offer customization options for creative designs. Curtain walls can also contribute to energy efficiency through features like thermal insulation and solar control systems, helping regulate indoor temperatures and reduce energy consumption.

What is the difference between a curtain wall and window wall?

The distinction between a curtain wall and a window wall lies in their structural characteristics. A curtain wall is a non-structural system that relies on the building's primary structural frame for support. It is designed to act as an outer layer, creating an enclosure while allowing for the entry of natural light. In contrast, a window wall is a structural system where the windows themselves provide support for the building, eliminating the need for additional framing elements. This design approach allows for larger expanses of glazing, providing unobstructed views and maximizing daylight penetration. While curtain walls offer flexibility in design and can accommodate various building shapes, window walls offer the advantage of simplicity in installation and potential cost savings by eliminating the need for separate structural support systems.

What are the two types of curtain walls?

There are two main types of curtain walls: stick-built curtain walls and unitized curtain walls. Stick-built curtain walls are constructed on-site, where individual components, such as aluminum frames and glass panels, are assembled piece by piece. This method allows for greater flexibility in design, making it ideal for projects with unique requirements or irregular building shapes. On the other hand, unitized curtain walls are prefabricated in controlled factory conditions. They are transported to the construction site as pre-assembled units, including fully glazed panels, frames, and other necessary components. Unitized curtain walls offer the advantage of faster installation, as the prefabricated units can be quickly fitted together, reducing on-site labor and time. Both types of curtain walls have their respective benefits, and the choice between them depends on project specifications and construction requirements.
