This framework facilitates the installation of large expanses of uninterrupted glass panels, giving rise to a harmonious blend of modernity and transparency.

The core components of a glass curtain wall include the glass panels themselves, the framing elements that support them, spandrel panels that conceal structural features, and sealants to ensure weather-tightness. These components work together to create an aesthetically pleasing and functionally sound building envelope.

Types of Glass Curtain Wall Systems

Diverse types of glass curtain wall systems cater to contemporary projects’ varied needs and architectural styles.

Stick-Built Curtain Walls

The stick-built curtain wall system involves assembling individual framing elements and glass panels on-site. This method offers design flexibility, enabling architects to adapt the system to suit their creative visions. Moreover, it is often chosen for its cost-effectiveness and ease of customization, making it a popular choice for various architectural applications.

Unitized Curtain Walls

In unitized systems, curtain wall units are pre-assembled in a controlled factory environment before being transported to the construction site for installation. These units ensure consistency, precision, and high-quality workmanship. As a result, unitized curtain walls are particularly well-suited for large-scale projects, especially high-rise buildings, where efficiency and quality control are paramount.

Spandrel Panels

Spandrel panels are non-vision glass or solid panels that occupy the spaces between floor slabs. Their primary function is to conceal structural elements and contribute to the overall finished appearance of the building’s exterior. They are essential components in achieving a cohesive and aesthetically pleasing facade.

Point-Supported Glass Walls

Point-supported glass curtain walls rely on strategically placed point fixings, such as bolts or clamps, to secure glass panels to a structural framework. This approach creates a sleek, minimalist appearance that aligns with modern design principles. Point-supported systems are often selected to achieve a clean and unobstructed visual aesthetic in architectural projects.
