Building Curtain Wall in China: A Comprehensive Guide

Introduction

The curtain wall system has become a hallmark of modern architecture, particularly in high-rise buildings. In China, companies like REXI Industries and Yuanda have pioneered the design and fabrication of curtain walls, contributing to the skyline of cities like Shanghai and Beijing. This guide explores the technical features, types, and advantages of curtain walls, providing insights into their role in contemporary architecture.

Technical Features of Curtain Walls

Curtain walls are non-structural cladding systems that protect buildings from the elements while allowing for aesthetic flexibility. Below is a comparison of key technical features of curtain walls:

Feature	Description
Material	Typically made from aluminum frames and glass panels, offering durability and lightweight properties.
Thermal Performance	U-values as low as 0.8 W/㎡.K, enhancing energy efficiency and reducing heating/cooling costs.
Water Penetration	High resistance to water penetration, with ratings up to 1000 Pa, ensuring building integrity.
Sound Insulation	Capable of achieving sound resistance ratings of Rw up to 68 dB, improving indoor comfort.
Aesthetic Flexibility	Offers a variety of finishes, colors, and glass types, allowing architects to create unique designs.
Installation Methods	Can be unitized, stick-built, or spider systems, each with specific installation techniques.

Types of Curtain Walls

Curtain walls come in various types, each suited for different architectural needs. Below is a comparison of the main types of curtain walls:

Type	Description
Unitized Curtain Wall	Prefabricated panels that are assembled in the factory and installed as complete units on-site.
Stick Curtain Wall	Constructed on-site using vertical and horizontal framing members, allowing for flexibility in design.
Spider Curtain Wall	Utilizes point-supported glass panels, creating a sleek, modern appearance with minimal framing.
Double Glazed Curtain Wall	Features two layers of glass with an air cavity, enhancing thermal insulation and energy efficiency.
Aluminum Stick Curtain Wall	Combines aluminum framing with glass panels, providing a lightweight and durable solution.

Advantages of Curtain Walls

Curtain walls offer numerous advantages, making them a popular choice for modern buildings. They provide excellent thermal insulation, reduce energy costs, and enhance the aesthetic appeal of structures. Additionally, they allow for large expanses of glass, maximizing natural light and views.

Key Benefits

Energy Efficiency: With advanced thermal performance, curtain walls help reduce energy consumption.
Design Flexibility: Architects can create unique facades that reflect the building’s purpose and environment.
Durability: Made from high-quality materials, curtain walls withstand harsh weather conditions.
Low Maintenance: Modern curtain walls require minimal upkeep, making them cost-effective over time.

Conclusion

The curtain wall system is an essential component of modern architecture in China, with companies like REXI Industries and Yuanda leading the way in innovation and design. By understanding the technical features and types of curtain walls, architects and builders can make informed decisions that enhance both the functionality and aesthetics of their projects.
