An Introduction to Glass Curtain Wall

Glass curtain walls is lightweight aluminum-framed facades housing glass, a building envelope that is intended to support only its own weight and withstand the effects of environmental forces such as wind. It is not intended to support the weight of a roof or floor. Instead, gravity loads and wind resistance transfer from the surface to the building’s floor line. Curtain wall systems range from standard prefabricated systems to specialized custom wall units. Increased costs often come with additional customization and larger sizing.

There are two main types of curtain walling construction: “stick” and “unitised”. In stick construction, the curtain wall frame is constructed mainly on site with mullions and transoms supporting glass, spandrel panels, metal panels and brise-soleils, connected piece by piece. Each mullion is usually supported by the floor or perimeter beams.In unitised construction, on the other hand, the curtain wall is composed of large units that are assembled in the factory, shipped to the site and erected on the building. Aluminium profiles are used to form the frame, which is normally one-storey high. Aluminium is typically used for facade frames because of its strength and stability. It is also highly durable, moisture and corrosion-resistant and 100% recyclable. Opening vents, glazing and infill panels are built into units before being transported to site. As with stick construction, each unit is usually supported by the floor or perimeter beams.

CURTAIN WALLING SYSTEMS
*STICK CURTAIN WALLING
Stick curtain walling systems are versatile and allow for the integration of other systems, such as sliding doors and windows. They tend to be less specialised and can be built by all types of fabricators as they are not dependent on having a large factory.
However, stick systems do require multiple steps to erect and seal the wall, which means more time is spent on site – an approximate rule of thumb would be that 70% of the work is carried out on site, with 30% in the factory. This incurs further costs, such as labors’ time.
UNITISED CURTAIN WALLING
For unitised curtain walling, about 30% of the work is done on site, while 70% is carried out in the factory. The complete assembly of the units in the factory brings a number of benefits.
These include:

• Improved quality control
• Concurrent manufacture and site preparation - units can be assembled while the structural frame is being built. The facade can also be completed a floor at a time, allowing parallel internal work
• Quicker installation, requiring less manpower on site
• No need for scaffolding
• Can be installed from the interior of the building. This is ideal for high towers or building sites where there is a tight footprint
• Less space is needed on site for layout

Another advantage of unitised systems is that, unlike stick systems, they do not transfer impact noises from floor to floor or horizontally from room to room. This is because the unitised panels are separated by linking gaskets. The different materials (ie, gasket to aluminium), become acoustically excited to different levels, thus creating full separation at the junctions between units.


Glass curtain walls are not exclusive to commercial applications. They also provide viable glazing solutions for residences as well.

We offer a range of aesthetical solutions, such as different styles of face caps from horizontal to vertical lining, to a more minimalistic look using structural glazing or clamping technologies and are available in different energy levels, from non-insulated to super high insulating.

We also provide tailored solutions for those projects that require a specific architectural design for their aluminium facade.

If you have interest, please contact us and tell us about your project by email or phone. We are happy to talk about estimates and our capabilities for Residential, Commercial and Custom Glass work.
