Stick-built Curtain Wall

Stick-built Curtain Wall

Product Overview

Stick-built Curtain Wall is a widely used modular exterior facade system in modern construction, designed to provide both aesthetic appeal and functional performance for commercial, high-rise, and large-scale public buildings. Unlike pre-assembled curtain wall systems, this type of curtain wall is constructed by installing individual components on-site, including vertical mullions, horizontal transoms, and facade panels. This assembly method offers exceptional flexibility, allowing for precise adjustments to fit unique building shapes, sizes, and design requirements. As a key element of building envelopes, it not only enhances the building’s visual appearance but also provides excellent weather resistance, thermal insulation, and sound insulation properties, creating a comfortable indoor environment while reducing energy consumption.

Core Design Features

The stick-built curtain wall system is characterized by its modular component design, which breaks the entire facade into small, manageable parts. Vertical mullions serve as the primary load-bearing structure, transferring the weight of facade panels and external loads such as wind and seismic forces to the building’s main structure. Horizontal transoms connect the vertical mullions, providing additional support and ensuring the stability of the facade panels. Each component is manufactured with high precision in factories, ensuring consistent quality and easy on-site installation. The facade panels, which can be made of glass, aluminum composite materials, or stone, are attached to the mullion-transom framework, allowing for diverse design options to match different architectural styles.

Assembly Process

The installation of a stick-built curtain wall follows a systematic on-site assembly process. First, construction teams install the vertical mullions, securing them to the building’s structural floor slabs or columns using specialized brackets. Next, horizontal transoms are connected to the mullions at predetermined intervals, forming a grid-like framework. Once the framework is in place, facade panels are fitted into the grid and secured with sealants and fasteners. Finally, weatherproofing seals are applied to joints between panels and components to ensure the system’s resistance to water penetration, air leakage, and wind pressure. This step-by-step assembly allows for real-time adjustments to accommodate any on-site variations, ensuring a perfect fit with the building’s structure.
