CURVED GLASS

The glass bending expertise of Tambest Glass Solutions belongs to the top class in the world. Our innovative and versatile production machinery combined with the personnel's three decades long expertise of glass bending guarantee the first-class measurement accuracy and optical quality of our products. Therefore, our company is internationally known as a supplier of very demanding curved glass solutions.

Several significant innovations of the field have come into being as the result of our company's development work, e.g. the bending methods applied to demanding spherical, conical and parabolic glasses.

The locations where curved glass is used are often technically very challenging, and several simultaneously interdependent factors affect the fact whether the desired glass is available as curved. We offer our customers consultation for the specification of the technical details related with glass structures as early as at the bidding stage. Therefore, the final offer is often tailored based on this consultation, case by case. 


Curved laminated glass

In the laminating proces two or more glass plates are joined by means of an elastic plastic film, using heat and pressure. Several types of film and glass may be applied in the process, to obtain different characteristics for the structures – according to the purpose of use.

Curved laminated glass protects from personal injuries; in the lowest protection class from falling, and in the sturdiest class from bullets and pressure waves caused by explosions. In addition to the protection class, the size of glass, its bending angle and bending form affect the durability classification of glass. When the number of glass layers and films is increased, it is possible to build multi-layer glasses for various, demanding protection needs.

The innovative and modern production machinery of Tambest Glass Solution and the expertise provided by the long-term activity in the business enable the manufacturing of challenging cylindrical, spherical, conical and parabolic laminated safety glasses. The laminating of curved glasses takes place in clean rooms, to ensure the faultlessness of the glasses. The maximum size of curved laminated glasses is 3210 x 6000 mm.


Curved tempered glass

The strength of tempered safety glass is based on the thermal treatment applied to the glass. The glass is heated to the temperature of approx. 650 °C, when the glass becomes softer and tensions disappear. After that, the glass is cooled rapidly, when a constant compression stress remains on the surface of the glass, and a constant tensile stress in the middle part.

The strength of tempered glass is increased to approx. fivefold compared with untreated glass. The safety characteristics of tempered glass are emphasized also when the glass is broken, when it breaks into small fragments without causing bigger wounds when getting into skin contact.

The most important stage in the manufacturing of tempered safety glass is to make the optical qualities of the glass to remain unaltered. In the bending & tempering process applied by Tambest Glass Solution the glass is being heated in two phases partly by means of circulating air, when the optics of the glass remain as ideal. The importance of the optical constancy is emphasized in large reflecting glass surfaces.

The design is often based on the need for bigger curved glass surfaces, concealed fixing and structures applied without casement and framework. Thanks to better durability, safety and bigger glass sizes, tempered curved glass is a reasonable alternative for these challenging structures.

Tambest Glass Solutions offers the most versatile product range of curved tempered glass products available on the market. The maximum size of curved tempered glasses is 2440 x 4200 mm.


Curved laminated tempered glass

The mechanical durability and tolerance of temperature  differences, characteristic of tempered safety glass as well as the qualities of laminated safety glass, binding fragments and burglar resistance, can be achieved simultaneously by combining two types of safety glass. Among other things, canopies, large glass surfaces used as balustrades, panorama elevators and the glass structures of main entrances are often realized using tempered and laminated curved glass.

The curved tempered laminated glass produced as the result of the cooperation of our laminating and tempering & bending ovens belongs to the highest rank of curved glasses. The maximum size of curved laminated tempered glasses is 2440 x 4200 mm.


Curved heat-strengthened glass

Curved heat-strengthened glass has been treated applying the same principle as in case of curved tempered glass. The difference to the actual bending-tempering is slower cooling in the treatment process, as well as lesser increase in the strength.

The strength of heat-strengthened curved glass is increased to approx. three-fold in comparison with untreated curved glass. The fragments of breaking heat-strengthened glass are rounder and less dangerous than the sharp-edged pieces coming into being when normal, non-strengthened glass is breaking, however bigger than those of tempered glass. Thanks to this quality, after it has been broken, heat-strengthened curved glass remains in its frames better than curved tempered glass does.

The most important phase in the manufacturing of curved heat-strengthened glass is to make the optical qualities of the glass to remain unaltered. The qualities of the curved heat-strengthened glass manufactured by Tambest Glass Solution remain as ideal. The importance of the optical constancy is emphasized in large glass surfaces. The maximum size of curved heat-strengthened glasses is 2440 x 4200 mm.

Curved insulating glass

Insulating glass is an element where two or more glasses have been joined in an air-tight manner together. Depending on the U value pursued; either air, argon or krypton is used between the glasses.

The curved insulating glass produced by Tambest Glass Solution is manufactured from the beginning to the end in our own factory. Thanks to the modern and versatile machinery and equipment, first-class materials and competent staff, our curved insulating glass products are of top quality, and deliveries are fast.

Curved insulating glasses can be built using different structures, and this makes it possible to achieve several protective qualities such as sun protection, thermal and sound insulation and burglary protection. Curved insulating glasses are available curved into cylindrical, spherical, conical and parabolic forms. The maximum size of curved insulating glass is 3210 x 6000 mm.
