How does glass curtain wall framing work?

Imagine that you are looking at the cityscape from your office window and see that wonderful view from above. As if you were sitting in one of the tall buildings in New York or in the Burj Khalifa in Dubai.  This is exactly what a glass curtain wall framing does, it is the technology that makes it possible.

But how does it work? And what are the benefits? Glass curtain wall framing is a type of framing system that uses vertical mullions and transoms to support glass panels. The panels are typically fixed in place, but can also be opened to provide access to the building's interior.

Understanding Glass Curtain Wall

A glass curtain wall is a facade system that employs large, floor-to-ceiling panels of glass. These panels are generally framed by aluminum and are mounted to the building with a support system that connects them to the structure of the building.

The result is an exterior that is almost entirely made of glass, which allows for panoramic views and natural light to enter the building. Curtain walls are most often used on high-rise buildings, where they can create an impressive visual impact.

How Does Glass Curtain Wall Framing Work?

Curtain walls are popular in high-rise and skyscraper construction because they offer an unobstructed view from inside and out.

In order to create a glass curtain wall, the building's frame must be designed to accommodate the extra weight of the glass. The frame is typically made of metal or aluminum, which can be designed to hold the weight of the glass without sagging.

The glass is then attached to the frame with either metal anchors or silicone sealant. The sealant is used in areas where the glass meets the frame, while the anchors are used to secure the glass to the frame in areas that are not visible from the outside.

The Benefits of Glass Curtain Walls

Glass curtain walls offer several benefits for both the building owner and the occupants. First, they let in natural light and provide views of the outdoors, which can brighten up a space and improve morale. They also allow for greater airflow and help to cool the building down in the summertime.

Glass curtain walls also provide a level of transparency that can be important for businesses or organizations that want to convey a sense of openness. And finally, they're an attractive option that can add value to a property.

Glass curtain walls gives also excellent sound insulation, which makes it an ideal choice for properties near airports, highways, or other areas that know activity and congestion and therefore a lot of noise.

Noise reduction is achieved by reducing sound transmitted through the glass itself and preventing airborne sound from entering the building through open windows.

The Different Types of Glass Curtain Walls

There are three main types of glass curtain walls: unitized, stick, and structural glazing.

- Unitized walls are made up of large panels that are factory-assembled and then installed on the building. These are typically used for taller buildings because they're stronger and can better withstand high winds.

- Stick walls are made up of individual pieces, or "sticks," that are installed on the building one by one. These are less expensive than unitized walls but are more time-consuming to install.

- Structural glazing is when the glass is actually held in place by being bonded or silicone sealed to the structure of the building. This is a more modern approach and is often used in combination with other framing materials like metal.

How to Choose the Right Glass Curtain Wall for Your Project

Here are a few things you need to take into account when you wanna choose the right glass curtain wall for your project.

First of all, you need to think about the size and shape of the glass panels. The bigger the panels, the more support they'll need. And, of course, you'll also need to take into account the weight of the glass.

Another thing to consider is the type of glass you want to use. There are a few different types of glass that are commonly used for curtain walls, including tempered glass, laminated glass, and insulated glass. Tempered glass is a type of safety glass that's been treated so that it breaks into small pieces instead of large shards, making it a good choice for areas where there's a risk of impact. Laminated glass is two or more layers of glass that are held together with a plastic interlayer. It's shatter-resistant and can be a good choice for areas where there's a risk of wind or seismic activity. 

And finally, insulated glass is two or more layers of glass that are separated by a spacer and sealed around the edges so that it traps air or gas between the layers. This makes it a good choice for areas where you need additional insulation.
