The 3 Technologies Used in Bending Glass

The field of glass architecture is always at the forefront of pioneering out-of-the-box innovations. Unique curves, shapes, and patterns dominate much of glass architecture, making it one of the most dynamic forms of architecture. In fact, recent design trends indicate that curved and bent glass in particular will become more and more prevalent in architecture.

The visual appeal of bent glass cannot be overstated. Furthermore, it is also very efficient to use in structural glazing applications.

The arching that bent glass is known for is actually a property that makes it load-resistant and can even help minimize deflections. In addition, when properly designed, the use of glass can reduce the use of building materials in general.

A product like this of immense value is certainly not easy to manufacture. But thanks to the development of bending technologies over the years, glass bending is only continuing to improve. Let’s take a look at these technologies:

Bending and Tempering

This process is done by first heating the glass in high temperatures and then bending it to the required radius. Lengthwise bending involves twisting the glass into the direction in which it flows. Crosswise bending is also an option. Between these two processes, lengthwise bending offers better optical quality. Tempered and bent glass provides great durability and strength against temperature variations.

Hot Bending

As the name suggests, the glass will be heated together with molds up to temperatures of 600°C. It can also be done through mechanical bending, which presses the glass into its desired shape. The glass will then be cooled to prevent residual tension. While hot bending enables fabricators to come up with a wide array of shapes, it does not add any extra mechanical strength or temperature resistance to the glass.

Cold Bending

Bent glass processed through this method is done by putting the glass into a frame which then mechanically bends the glass into its desired shape. The glass is then screwed or glued directly into the frame which will then be ready for installation. With this method, there is only a slight bending of the glass, meaning its bending radius is high.
