Transforming Design Aesthetics: The Beauty of 4-Sided Toggle Glazed Curtain Wall Systems

Toggle glazed (TG) curtain wall systems are a type of curtain wall system that uses a toggle mechanism to secure the glass to the frame, providing a seamless finish. These curtain wall systems provide superior all-glass facades with enhanced aesthetic appeal, reduced installation labor and superior thermal performance for a variety of low-rise applications. In this article, we discuss six key benefits of 4-sided toggle glazed curtain wall systems as well as the features of Kawneer’s Clearwall® Curtain Wall System.  

Key Benefits 

The adoption of 4-sided toggle glazed curtain wall systems brings a wide range of advantages that benefit the aesthetics of a building along with its operational efficiency, making them a popular choice in commercial projects. Here are six key features of 4-sided toggle glazed curtain wall systems: 

1. Aesthetic Appeal: Toggle glazed systems allow for a sleek and uninterrupted monolithic all-glass facade, contributing to the modern look desired in architectural designs, particularly for low-rise buildings. This design meets demands for aesthetics while providing the appearance of a structural silicone glazed (SSG) system at a lower cost.  
2. Labor Efficiency: These solutions help simplify installation for glaziers and contractors by reducing the amount of field-applied structural silicone, as toggles directly capture the glazing, which can lead to less labor required on-site and can help minimize installation time and costs while enhancing overall safety during installation.  
3. Thermal Performance: Most toggle glazed systems are thermally broken, which improves energy efficiency by reducing heat loss and gain, contributing to more environmentally sustainable designs. Enhanced insulation is an important factor in helping minimize HVAC costs in commercial buildings. 
4. Design Flexibility: The systems can accommodate various architectural requirements, including different mullion depths and profiles. This adaptability means architects can meet specific structural and aesthetic demands without compromising performance.  
5. Resiliency: Many 4-sided toggle glazed systems are designed to meet stringent weather resistance requirements. They may be tested for performance against high winds, seismic activity and impact, making them suitable for a wide range of environments, including hurricane-prone areas.  
6. Integrated Features: These systems often incorporate features such as enhanced drainage solutions and air barriers to improve overall building envelope performance, ensuring weather-tight installations that protect against water infiltration.  

In summary, 4-sided toggle glazed systems offer a sleek, modern aesthetic appeal for projects, while their practical installation features ensure they serve as the ideal solution for a variety of building applications.
