Ultimate Guide: Types of Curtain Walling Explained

Understanding Curtain Walling

Curtain walling is a non-structural exterior wall system supported by a building's structural framework. It provides numerous benefits, including aesthetic appeal, thermal insulation, and weather resistance. This guide breaks down the various types of curtain walling and their characteristics.

1. Stick System

The stick system is one of the most common types of curtain walling. It consists of vertical and horizontal elements assembled on-site. Here’s how it works:

1. Framework Installation: Begin by installing the primary framework, which acts as the support.
2. Stick Components: Attach vertical and horizontal mullions (vertical framing members) and transoms (horizontal members).
3. Glazing Installation: Finally, set the glass panels into the frames, securing them with sealants.

2. Unitized System

Unlike the stick system, the unitized system involves prefabricated panels that are manufactured off-site. Follow these steps to understand its application:

1. Panel Fabrication: Fabricate large sections of the wall, which include framing and glazing units.
2. Transporting Panels: Carefully transport the pre-built panels to the construction site.
3. Installation: Attach the panels to the building structure using lifting equipment, ensuring quick and efficient assembly.

3. Structural Glazing System

This type utilizes minimal framing and allows for a sleek, modern appearance by bonding the glass directly to the structure. Here's how to implement it:

1. Surface Preparation: Prepare the structural surface for optimal adhesion with specific sealants.
2. Glass Installation: Fit the glass panels tightly against the structure, securing with structural silicone.
3. Weatherproofing: Ensure all edges are sealed to prevent water ingress.

4. Curtain Wall Materials

Curtain walling can be constructed from various materials, which can significantly influence aesthetics and performance. Key materials include:

• Aluminum: Lightweight and corrosion-resistant, making it a popular choice.
• Glass: Provides transparency and can be treated for better insulation.
• Steel: Heavy-duty and ideal for high-rise buildings due to its strength.

5. Benefits of Curtain Walling

Choosing curtain walling can enhance a building's design significantly. The primary benefits include:

• Energy Efficiency: Improved thermal performance reduces energy costs.
• Aesthetic Appeal: Offers a modern and sleek look that can elevate any building's architecture.
• Flexibility: Adaptable for different building shapes and sizes.

Conclusion

In conclusion, understanding the various types of curtain walling is crucial for architects and builders alike. Each system has its own unique advantages, making it essential to select the right solution based on project requirements.
