Types Of Aluminium Curtain Walling

Aluminium curtain walling is available in various types, including the stick system, unitised system, and semi-unitised system, each offering distinct advantages and applications.

Architects and builders can select the most suitable type based on project requirements, design preferences, and installation considerations.

Stick System

The stick system of aluminium curtain walling involves on-site assembly and installation of individual components, providing flexibility in design and construction.

It offers architects and builders the freedom to customise the facade based on specific project requirements and structural considerations, making it a popular choice for unique architectural designs.

One of the standout characteristics of the stick system is its adaptability to different building shapes and sizes, allowing for intricate and customised designs.

This flexibility extends to the choice of materials, finishes, and colours, enabling a seamless integration with the overall aesthetic vision.

The installation process of the stick system is efficient and precise, giving construction teams the ability to execute complex designs with ease.

Unitised System

The unitised system of aluminium curtain walling involves off-site fabrication and assembly of pre-engineered units, streamlining the installation process and ensuring consistent quality.

This approach offers time and cost efficiencies while maintaining design precision and structural performance, making it suitable for high-rise buildings and large-scale projects.

With off-site fabrication, the assembly of pre-engineered units allows for simultaneous work on different parts, significantly reducing the overall installation time.

The unitised system also enhances quality control by minimising on-site variables and potential errors, resulting in a more reliable and consistent finished product.

The versatility of the system extends its applications to various architectural designs, facilitating the incorporation of complex shapes and structural demands in high-rise buildings.

Its modular nature enables efficient customisation, accommodating the specific requirements of different projects and site conditions.

Semi-Unitised System
