What are the five requirements of a curtain wall?

A well-designed curtain wall system must meet these five essential requirements:

1. Structural Performance: The curtain wall must withstand wind loads, seismic movements, and external pressure without deformation.
2. Weather Resistance: It should provide waterproofing, air tightness, and insulation to protect the building from rain, wind, and temperature variations.
3. Thermal and Acoustic Insulation: Energy efficiency is critical, so the system must offer heat insulation and reduce noise transmission.
4. Durability and Maintenance: High-quality aluminum facades and glass panels should resist corrosion, aging, and environmental stress while being easy to clean and maintain.
5. Aesthetic Appeal and Flexibility: Curtain walls should enhance the building’s visual identity, supporting modern architectural designs with various finishes and configurations.
