Aluminium Curtain Wall Section

An Aluminium Curtain Wall Section is an engineered aluminum framing profile used in curtain wall systems to support glass panels and create a durable, weather-resistant building façade. As a non-structural cladding system, it protects the building interior from wind, rain, heat, and other environmental elements while providing a modern architectural appearance.

Key Components of an Aluminium Curtain Wall System

Mullions (Vertical Members)
Mullions are the primary vertical structural components that are anchored to the building structure. They transfer dead loads and wind loads safely to the building frame.

Transoms (Horizontal Members)
Transoms are horizontal framing members installed between mullions. They support glass panels and help distribute loads across the curtain wall system.

Thermal Break
A thermal break is an insulating material, typically polyamide or polyurethane, placed between the interior and exterior aluminum sections. It reduces heat transfer and improves energy efficiency.

Gaskets and Sealants
EPDM rubber gaskets and high-performance sealants create airtight and watertight seals around glass panels, preventing water leakage and air infiltration.

Pressure Plates and Cover Caps
Pressure plates secure the glazing panels to the frame, while decorative cover caps conceal fasteners and provide a clean architectural finish.

Types of Aluminium Curtain Wall Systems

1. Stick Curtain Wall System

• Fabricated and assembled on-site.
• Glass and aluminum sections are installed piece by piece.
• Suitable for low-rise and medium-rise buildings.
• More flexible for custom architectural designs.
• Generally offers a lower initial installation cost.

2. Unitized Curtain Wall System

• Manufactured and glazed in a factory-controlled environment.
• Delivered to the project site as pre-assembled units.
• Ideal for high-rise commercial and residential buildings.
• Faster installation and improved quality control.
• Reduces on-site labor and construction time.

Applications of Aluminium Curtain Wall Sections

• Commercial Office Buildings
• Corporate Headquarters
• Shopping Malls
• Hotels and Resorts
• Hospitals
• Educational Institutions
• Airports and Transportation Hubs
• High-Rise Residential Towers

Benefits of Aluminium Curtain Wall Systems

✔ Modern and attractive building appearance
✔ Excellent weather resistance
✔ Improved thermal insulation
✔ Increased natural daylight penetration
✔ Low maintenance requirements
✔ High structural strength with lightweight materials
✔ Long service life and corrosion resistance

Custom Curtain Wall Solutions

Professional curtain wall manufacturers can provide customized aluminum sections based on:

• Wall depth requirements (50mm, 65mm, 80mm, 100mm, 120mm, etc.)
• Structural glazing or capped glazing systems
• Double-glazed or insulated glass units (IGU)
• Wind load and seismic performance requirements
• Building height and façade design specifications

Aluminium curtain wall sections are widely used in modern architecture because they combine strength, aesthetics, energy efficiency, and long-term durability, making them one of the most preferred façade solutions for contemporary buildings.
