An aluminium curtain wall is a non-structural, exterior cladding system that covers the building’s façade. It typically consists of an aluminium frame, glass or other infill materials, and various components that provide insulation, weather resistance, and visual appeal. Curtain walls create a sleek, modern look and are commonly used in contemporary architecture.

Aluminium Frame: The primary structural element of the curtain wall is the aluminium frame. This frame is designed to support the glass or other infill materials and attach to the building structure.

Infill Materials: The spaces within the aluminium frame are filled with materials such as glass, metal panels, or other cladding materials. The choice of infill materials can impact factors like insulation and aesthetics.

Glazing: Glass panels are commonly used as infill materials in curtain walls. The glass can vary in type, thickness, and coatings for insulation and aesthetics.

Sealants & Gaskets: To maintain weather resistance and prevent water infiltration, curtain walls are equipped with sealants and gaskets.

Thermal Breaks: To enhance energy efficiency, some curtain wall systems incorporate thermal breaks, which are insulating materials placed between the inner and outer aluminium profiles.

Spandrel Panels: Spandrel panels are opaque panels used to fill areas of the curtain wall that are not covered by glass. These panels can be made from various materials.

Mullions & Transoms: These horizontal and vertical members provide structural support and connect individual frame sections.

Sunshades & Louvers (optional): Some curtain wall systems include sunshades or louvres for shading and improving energy efficiency.

Aesthetics: Aluminium curtain walls offer sleek, modern aesthetics that can be customized to suit a wide range of architectural styles.

Energy Efficiency: Modern curtain walls often include high-performance glazing and insulation, contributing to the energy efficiency of the building.

Daylighting: The extensive use of glass in curtain walls allows for ample natural light, reducing the need for artificial lighting and providing a more comfortable indoor environment.

Weather Resistance: Properly designed and installed curtain walls provide protection against weather elements, including wind, rain, and temperature fluctuations.

Design Flexibility: Curtain walls offer design flexibility, allowing architects to create unique and visually striking building facades.

Commercial Buildings: They are commonly found in office buildings, hotels, and shopping centres.

Residential Buildings: Modern apartment complexes and luxury homes may feature curtain walls for their contemporary aesthetics and energy-efficient qualities.

Institutional Buildings: Curtain walls are used in schools, hospitals, and government buildings.

Retail Spaces: Shopping malls and retail stores often use curtain walls for their striking appearances and ability to showcase merchandise.

Specialty Buildings: Museums, airports, and cultural institutions may incorporate curtain walls for their design and functionality.

Proper maintenance is essential for the longevity and performance of aluminium curtain walls. This includes regular cleaning of the glass and frames, inspection of sealants, gaskets, and weatherstripping, and addressing any issues promptly to prevent water infiltration.

Aluminium curtain walls provide a visually striking, energy-efficient, and durable exterior cladding system for modern buildings. They offer flexibility in design and can be customized to meet various architectural requirements. Proper installation and maintenance are crucial to ensuring their performance and longevity.
