Aluminium curtain walling is becoming one of the most sought-after architectural features in both residential and commercial projects. Known for combining large expanses of glazing with strong yet lightweight frames, curtain walling brings natural light, energy efficiency, and contemporary design together in a single system. But what exactly is curtain wall glazing, how does it work, and what trends are driving its popularity today?
Despite its growing use in both homes and offices, the question what is curtain walling is still widely asked. Put simply, curtain wall systems are non-load-bearing layers of glass and aluminium that sit on the outside of a building’s main structure. They act as a protective “curtain” against wind, rain, and other weather conditions, while still allowing light to flow into the building.
Unlike standard windows, curtain wall glazing doesn’t carry the weight of the roof or floors. Instead, it hangs from the building frame, which means lighter materials can be used. This flexibility makes curtain walling an attractive option for large spans of glazing, unique designs, and even curved facades.
Glazed curtains allow for maximum natural light to flood into the home while still offering incredible, unbroken views of the outside. With Express aluminium curtain walling, you also have the freedom to integrate a variety of specific window types and external doors, including sliding doors and bifold doors, directly into the curtain. This means you can enjoy the same benefits of protection and insulation while also opening up easy access to the garden.
“At Express, we’ve seen aluminium curtain walling become increasingly popular in residential projects, not just commercial buildings. Homeowners are drawn to the combination of uninterrupted views, outstanding weather protection, and the flexibility to incorporate sliding or bifold doors directly into the curtain wall itself. It’s a system that brings lasting value as well as light into a property.”

When choosing aluminium curtain walling, it helps to understand the two main construction types. These refer to how the curtain wall is built and installed:
Stick System
Installed piece by piece on site, the stick system allows for flexibility and customisation. It is often used in domestic projects where bespoke sizes and layouts are required.
Unitised System
Prefabricated in large panels within a factory and then delivered to site, the unitised system is quicker to install and commonly used in large commercial projects such as offices and high-rise buildings.
Both types use lightweight aluminium and curtain glazing, but the choice usually depends on the size of the project and how much flexibility is needed during installation.
While types describe how curtain walls are built, curtain wall systems focus on how they protect a building from the elements. There are three main systems available:
A common question is why not choose a fully sealed curtain wall system every time. The answer is that it isn’t always necessary. Unless the glazing is directly protecting your interior living space, water-managed or pressure-equalised systems usually provide all the protection you need without the higher cost of a fully sealed system.
Architects are increasingly using curtain walling to design buildings with striking forms. With modern engineering and flexible curtain glazing, facades can feature curves, waves, or angular designs that stand out while blending with their surroundings.
With energy performance high on the agenda, curtain wall systems are now designed to deliver excellent insulation. Features such as triple glazing, thermal breaks, and lower U-values mean aluminium curtain walling helps to keep homes warm in winter and cool in summer.
Sustainability plays a growing role in construction. Many aluminium curtain walling systems now use recycled materials and are designed for long life spans. Paired with laminated glass that improves safety and insulation, this makes curtain walling a strong choice for environmentally conscious homeowners.
Technology is reshaping modern curtain wall glazing. Some systems now incorporate photovoltaic cells within the glass itself. This means curtain walling can capture solar energy during the day and generate power for lighting or other uses in the evening.
Another key trend is maximising daylight. Larger panes of laminated glass with thinner aluminium frames are being used to brighten interiors. This not only reduces the need for artificial lighting but also improves wellbeing and comfort inside the home.
Curtain walling can incorporate a variety of glazing options depending on performance needs. These include advanced double glazing for insulation, solar control glass to manage heat and light, and laminated glass for added strength and UV protection.
The main considerations are cost and installation. Aluminium curtain walling is more complex to design and fit compared to standard windows, which can increase budgets. Installation often requires scaffolding or specialist lifting equipment for large glass panels, making it essential to use an experienced installer.
Not at all. While curtain wall systems are common in offices and public buildings, more homeowners are now choosing aluminium curtain walling for residential properties. It works especially well for large extensions, atriums, and open-plan living spaces.
Aluminium curtain walling has moved far beyond its commercial roots and is now shaping the look and feel of contemporary homes. From curved facades and laminated glass safety features to energy efficiency and integrated smart technology, curtain wall glazing continues to evolve.
With Express aluminium curtain walling, you can also enjoy design freedom, integrating windows, sliding doors, and bifold doors directly into the curtain wall for easy access to outdoor areas. This allows you to take full advantage of natural light, uninterrupted views, and a system that can be tailored to suit both your home and its location.
