Bent glass

Toughened bent glass

Bent glass

Bent glass links the creativity of the architect to the advantages and quality of modern glass products. Bending glass is a process in which a flat glass panel is heated in a controlled way. Through gravity, the glass bents and assumes the shape of the underlying mold. Bent glass is often used as roof glazing in light domes, porches and shopping galleries, to round the corners of curtain walls or façades corners, as part of furniture, bent automated doors or shower screens.

Glass is tested on transparency. In this way, for millennia, glass has influenced human life time and again. This is still true in the future due to the durability of the basic material – sand. Curved glass makes it possible that architectural and industrial design will make a transition to a new third dimension.

Single bent glass

Bent glass panels of single glass can be cooled down free of tension, according to the thermal shaping process, so they meet the high technical standards and can be processed into layered safety or insulation glass. The panels cooled without tension can be cut and drilled and the sides can be altered. Single bent glass is mainly applied to small objects for daily use, such as platters, bowls or furniture elements (for instance cupboard doors). Whenever safety and protection is important, Bent safety glass is used. It is often used in lamps and showcases, to show displays for sale, slot machines and numerous smaller, often technically high-quality products.

Layered bent glass

Curved glass

Just as it is true for flat glass, curved glass can have a safety function because an intermediate layer of synthetic material is applied between two panels. Curved layered safety glass can be manufactured in the usual standardized classifications that are valid for the whole of Europe (EN 356 and following). Most glass types can be processed into layered safety glass, but also in curved shape. Interesting decorative, but also functional, possibilities arise from the large diversity of the available “Interlayers”. In other words, the diversity of the products can be integrated into the synthetic intermediate layer and therefore add an esthetic aspect to safety.
Where safety and protection from cuts in possible glass fractures plays a role, curved layered safety glass is required. It is especially used for: railings, façade elements, glass in elevators, doors, ceiling glass, windshields, bullet and explosion proof glass.

Tempered bent glass

The safety aspect can also be achieved for both flat and curved glass, by cooling the heated glass down in a controlled way. This process has two safety aspects: on the one hand, the mechanic firmness of the glass panel is significantly increased, local screw connections are made possible, the impact and scratch protection and the shock resistance also improve considerably. Moreover, on the basis of the “tempering” of the glass panel, numerous small splinters occur in case the glass breaks. These splinters can hardly cause serious injuries given their size and weight.
Where a higher mechanical strength is required, hardened curved glass or curved durci are used: showers, ovens or cookers, screwed on glass panels in railings, façades or separation walls and many movable parts such as in a ship and vehicle construction. 

Bent insulation glass

Similar to the flat insulation glass, curved insulation glass can also be manufactured. The insulation function is reached because two curved panels with a hollow filled with air are assembled by means of a frame. This “built-in” layer of air has an insulating function. Nowadays, this effect is reinforced by the fact that people do not merely use curved glass that is covered in a special layer, which poorly reflects or conducts the heat, but also fills the intermediate space with special gasses that do not let in much heat.
Curved glass links freedom in architectural design to the advantages and qualities of glass products. Curving the glass concerns a processing in which a flat glass panel is heated in a controlled way. Gravity forces the glass to curves and assume the shape of the underlying mold. Curved glass is often used as roof glazing in light domes, porches and shopping galleries, to round the corners of curtain walls or façades corners, as part of furniture, staircases, curved automated doors or shower screens.



Bending glass

The glass is highly flexible at a high temperature in the infrared range.
All conceivable shapes can be realized with special moulds and the right know-how.
