What is curtain walling?
Curtain walling is a lightweight, non-load-bearing façade system installed to the outside of a building. Unlike a structural wall, it does not carry the weight of the floors or roof. Instead, the building’s main structural frame supports those loads, while the curtain walling creates an external envelope that protects the interior from weather and helps shape the appearance of the building.
Aluminium is particularly well suited to curtain walling because it is strong, relatively lightweight and resistant to corrosion. Aluminium frames can support large areas of glazing while maintaining clean, slim sight lines. This makes curtain walling especially attractive for commercial projects where architects want to maximise daylight and create a contemporary appearance.
Curtain walling can incorporate different types of infill, including vision glass, spandrel panels and insulated panels. Windows and doors can also be integrated into the system, creating a coordinated façade rather than a collection of separate elements. With careful specification, the system can contribute to thermal performance, weather resistance, acoustic comfort and long-term durability.
Curtain Walling with Alimatic AAS Ltd
Aluminium Curtain Walling
Alimatic Architectural complete Aluminum Curtain Walling Suite successfully balances the aesthetic requirements of architects with the functional needs of contractors and occupiers. By bringing together compatible components within a comprehensive suite, the system helps simplify specification, fabrication and installation while supporting high standards of quality and cost efficiency.
With wide-ranging designs, the durable aluminium curtain wall frame can be infilled with glass to provide an elegant, consistent appearance while allowing natural light to flood into a building. A full range of aluminium windows and doors can be integrated within the curtain walling, helping designers achieve a cohesive external façade and practical access, ventilation and occupancy solutions.
Key Features of Curtain Walling
Aluminium curtain walling offers excellent thermal performance and can achieve low U-values. This can help reduce heat transfer through the building envelope and support more efficient commercial buildings when the complete façade is correctly designed, specified and installed. Good thermal performance can also contribute to a more comfortable internal environment.
Slim, constant sight lines for both the mullion and transom give a uniform appearance across the suite. This creates clean architectural lines and helps different sections of the façade work together visually. For modern commercial developments, that consistency can make a significant difference to the overall character of the building.
High-quality components are designed for long-term durability. Aluminium provides a robust framing material that can withstand the demands associated with commercial applications, while suitable finishes and components can help maintain the appearance and performance of the façade over time.
Curtain walling offers full compatibility with our range of window and door systems, including the integration of our anti-finger trap stile. This compatibility can make it easier to create coordinated façades where entrances, opening windows and fixed glazing need to work together. It can also help support practical requirements around accessibility, safety and everyday building use.
A choice of box sizes for the structural members allows flexibility of design while helping ensure cost efficiency is achieved. Designers can select appropriate member dimensions for the requirements of a project rather than relying on a single configuration. This can provide greater freedom when balancing structural requirements, aesthetics and budget.
Glazing, including vision glass, spandrel panels or insulated panel types, can be used in a variety of thicknesses. This gives architects and contractors greater choice when developing the façade specification. Different combinations can be used to achieve the desired balance of daylight, privacy, insulation, appearance and performance.
The Benefits of Curtain Walling for Commercial Buildings
Curtain walling can provide far more than an attractive external finish. When properly designed and installed, it can support the performance, comfort and usability of a commercial building while giving architects considerable creative freedom. Below are some of the main benefits worth considering.
1. Creates a modern architectural appearance
One of the most visible benefits of aluminium curtain walling is its clean and contemporary appearance. Slim framing and large areas of glazing can create a sophisticated façade that makes a strong first impression on customers, clients, employees and visitors.
2. Maximises natural light
Large glazed areas allow more daylight to enter internal spaces than many traditional façade designs. Natural light can make offices, reception areas, retail environments and communal spaces feel brighter, more open and more welcoming.
Increasing daylight can also reduce the need for artificial lighting during suitable periods of the day. Although the overall impact depends on building orientation, glazing specification and lighting controls, effective façade design can contribute to a more efficient and pleasant working environment.
3. Supports thermal efficiency
Commercial buildings need to manage heat loss and heat gain carefully. Curtain walling systems with appropriate thermal performance can help limit unwanted heat transfer through the external envelope.
Low U-values can support improved energy performance, particularly when the curtain walling, glazing, insulation and other building elements are considered as part of one coordinated design. Better thermal control can help maintain comfortable internal temperatures and may reduce reliance on heating and cooling systems.
4. Offers design flexibility
Every commercial development has different requirements. Curtain walling provides flexibility through different frame configurations, box sizes, glazing options and integrated windows and doors.
This allows the façade to be designed around the building rather than forcing the project into a rigid system. Architects can create horizontal or vertical emphasis, incorporate large glazed areas and introduce panels where privacy or visual variation is required.
5. Provides a lightweight façade solution
Curtain walling is designed as a non-load-bearing external envelope. Its relatively lightweight construction can provide advantages during the design and construction process, although the final specification must always account for structural requirements, wind loading and other project-specific considerations.
Using aluminium also provides a strong framing solution without the weight associated with some alternative materials. This combination of strength and low weight contributes to the versatility of aluminium curtain walling.
6. Integrates windows and doors
A commercial façade needs to accommodate more than fixed glazing. Opening windows may be required for ventilation, while doors provide access and can form important entrances and escape routes.
The compatibility of Alimatic AAS Ltd’s curtain walling with its aluminium window and door systems allows these elements to be integrated into the façade. This can produce a more consistent appearance and simplify the relationship between different parts of the building envelope.
7. Supports long-term durability
Commercial façades are exposed to changing weather conditions throughout the year. Aluminium curtain walling offers a durable solution that can be specified for demanding external applications.
Using high-quality components can help support reliable long-term performance, while appropriate fabrication, installation and maintenance remain important to protecting the system. A durable façade can help reduce disruption and the need for premature replacement.
Overall, curtain walling offers a combination of aesthetic freedom and practical performance that makes it well suited to modern commercial construction. From improved daylight and thermal performance to durable materials and integrated windows and doors, the system can support many of the priorities that matter to architects, contractors, developers and building occupiers.
Things To Consider…
Although curtain walling offers significant benefits, choosing the right system requires careful planning. The façade should be considered as part of the wider building design rather than treated as an isolated feature.
Thermal performance is an important starting point. Consider the required U-values, glazing specification, solar control and how the curtain walling will interact with the rest of the building envelope. The building’s orientation and intended use should also influence the design.
Structural and environmental requirements also need attention. Wind loads, building height, exposure, drainage, weather performance and installation conditions should be assessed as part of the project specification. The selected system must be appropriate for the particular building and its location.
It is also worth considering how windows and doors will be incorporated. If opening elements are required, choosing compatible systems can help maintain consistent sight lines.
Finally, quality of fabrication and installation matters. Even a well-designed curtain walling system needs accurate manufacture, correct installation and appropriate ongoing maintenance to achieve the intended performance. Working with an experienced supplier can therefore be an important part of achieving a successful result.
In Conclusion: Build a Brighter Commercial Future
Curtain walling can transform the appearance and performance of a commercial building. Its combination of slim aluminium framing, extensive glazing, design flexibility, durability and compatibility with windows and doors makes it a compelling choice for many modern developments.
From maximising natural daylight to supporting thermal efficiency and creating a consistent architectural identity, the benefits extend well beyond appearance. With the right specification, curtain walling can help create commercial spaces that are attractive, practical, comfortable and built for long-term use.
