Technical Parameters
What Is Bent Glass
Bent glass also known as curved tempered glass, is a type of glass that has been shaped or formed into a curved shape through a process of heating and then cooling the glass. This process, known as tempering, strengthens the glass and makes it more durable and resistant to breaking.
Advantages of Bent Glass
Unparalleled design freedom
One of the key advantages of bent glass is the unparalleled design freedom it offers. Unlike flat glass, which is limited to straight lines and right angles, bent glass can be shaped into virtually any form or curve.
Enhanced natural light and views
Another major advantage of bent glass is its ability to maximize natural light and views. The curved shape of the glass allows for increased sunlight penetration, creating bright and inviting spaces inside buildings.
Improved structural integrity
Contrary to popular belief, bent glass is not only visually appealing but also highly durable and structurally sound. The bending process strengthens the glass, making it more resistant to external forces such as wind and impact. This enhanced structural integrity allows architects to design buildings with larger glass surfaces, reducing the need for additional support structures.
Energy efficiency and sustainability
In an era where sustainability is a top priority, bent glass offers significant advantages in terms of energy efficiency. The curvature of the glass helps to reduce heat transfer, improving insulation and reducing the reliance on artificial heating and cooling systems. This not only reduces energy consumption but also lowers carbon emissions, making bent glass an eco-friendly choice for modern architecture.
Versatility and adaptability
Bent glass is extremely versatile and can be used in a variety of structures including commercial buildings, residences, museums, and even furniture design. Whether it is a curved glass roof, spiral staircases, or custom-shaped windows, curved glass can add a touch of elegance and sophistication to any architectural project.

Types of Bent Glass
This is normal annealed glass that's been bent to the required form. Less strong than the other types of bent glass, annealed curved glass is used its look is more important than the increased costs that come with greater strength and safety or durability. These may include display cases or decorative pieces.
Tempered curved glass is strengthened using heat and in addition to being bent to the required curvature level. The result is a hard glass material that can be used in many demanding applications, including architectural doors and windows. Curved tempered glass is also popularly used for internal partitions of buildings or even staircase railings.
Unlike normal tempered glass that is flat, 3d curved tempered glass bends on the edges. It's essentially used to protect the screens of electronic devices with contoured ends. These include smartphones, tablets, and smart watches. The curved edges allow it to seamlessly fit the ends of these screens, offering edge-to-edge protection against scratches and breakage or other forms of damage.
Laminated curved glass is made by sandwiching glass sheets between a pvb plastic interlayer to produce a strong type of glass that will not only break safely, but one that will not break easily. Common uses of the curved laminated glass include the windshields of automobiles and similar applications where safety and robustness are important requirements.
Gorilla glass, a kind of chemically-strengthened glass, can be bent for a variety of uses. Curved gorilla glass is tough, scratch resistant, and less likely to break from normal impact forces. This type of glass is often used for car windshield glass, mobile or smart watch screens, and curved television sets.
Application of Bent Glass
Architectural glazing: Bent glass is widely used in architectural glazing to create dramatic facades, sweeping canopies, and curved curtain walls. Its ability to bend and shape light allows architects to design buildings with fluid forms and dynamic geometries that capture the imagination.
Interior design: Bent glass is employed in interior design to define spaces, enhance spatial flow, and create visual interest. Curved glass partitions, balustrades, and feature walls add a sense of openness and transparency to interiors, while curved glass furniture and fixtures provide a contemporary aesthetic.
Automotive design: Bent glass is an integral component of automotive design, used in windshields, sunroofs, and side windows to provide panoramic views and aerodynamic styling. Its strength, clarity, and impact resistance make curved glass an essential element in vehicle safety and aesthetics.
Retail displays: Bent glass is utilized in retail displays and showcases to showcase products, create focal points, and draw attention to merchandise. Its sleek and modern appearance enhances the visual appeal of retail environments, elevating the customer experience and brand image.
Art and sculpture: Bent glass is a popular medium for artists and sculptors seeking to create dynamic and expressive works of art. Its transparency, reflectivity, and malleability allow for the creation of captivating installations, sculptures, and architectural features that engage and inspire viewers.
Process of Bent Glass
Cutting: The first step is to cut the flat glass sheets into the desired shape and size before any curving takes place.
Heating: The cut glass is then heated in a furnace or kiln at high temperatures. The exact temperature and time depend on the type and thickness of the glass being used.
Bending: Once the glass reaches the appropriate temperature, it becomes pliable and can be shaped into the desired curve using molds or other specialized tools. The glass is carefully bent into its curved form and then allowed to cool down and solidify while maintaining the curved shape.
Annealing: After bending, the curved glass undergoes a process called annealing, where it is slowly cooled at a controlled rate to relieve internal stresses and ensure its structural integrity.
Glass bending technologies
Bending and tempering
Most commonly in the bending and tempering process, the glass is first heated to over 630 °c. Once heated, the glass is then bent to its target radius in the bending station.
Although bending systems most commonly produce cylindrical forms, it's not uncommon to produce small bi-directional bending by angling the glass during the process.
The glass can be twisted into the direction in which the glass flows, which is known as lengthwise bending. It can also be bent crosswise across the glass flow, which is called crosswise bending.
Hot bending
In hot bending, the manufacturer uses molds, which allow the glass to adopt the desired form. The glass, as well as the mold, is then heated up to 580–600 °c.
Bending can be solely based on gravity. Alternatively, the glass bending process can be assisted in which a mechanical bending press forces the glass into a target shape. The shape is then slowly cooled to avoid any residual tension in the glass.
Bending technology allows producers to create a wider range of shapes, for instance, a tighter radius and non-cylindrical shapes. The hot bending process itself does not add mechanical strength to the glass nor the ability to tolerate temperature variations.
Cold bending
Cold bending can be carried out after the glass is already tempered. By doing so, the glass adopts the mechanical properties of safety glass.
As the name indicates, cold bending is performed with the factory's natural temperature. The process starts by putting the glass into a frame that mechanically bends the glass into the desired frame shape. In the frame installation process, the glass is glued or screwed directly into the frame. The frame is then ready for installation into the building.
The bending radius is normally quite high, which means there's only a slight bending of the glass. The thinner the glass, the easier it is to bend from a mechanical perspective. The shape, however, can also have a twisted design.
Cold bending can be performed for an entire insulated glass unit or for single glass lites. When bending a full insulated unit, the sealant is under multiple forces. Since cold-bent glass has not been around long enough, it's hard to judge its durability.
Lamination bending
Lamination bending is a process that somewhat combines cold and hot bending, as well as lamination. For bent laminated glass, the most common workflow is to first bend the glass sandwich – with the desired number of glass sheets in the interlayer – and then proceed with the autoclave process.
Thanks to the autoclave process, it's possible to join two pieces of glass together with an interlayer. The required processing temperature inside the autoclave is around 120–140 °c; the pressure is about 12 bars.
Bending is carried out with a mechanical fixture before the autoclave process, and the original bending radius needs to be smaller than the target shape.
