Curved glass makes buildings flow

The sleek and sophisticated appearance of glass offers unparalleled style, making it among the top material choices for everything from buildings to trophy cases. Curved or bent glass is one of the fastest growing architectural trends as it is being increasingly used to add dramatic movement and dimension to traditionally static structures, taking them to the next level.

This trend includes spiral staircases, skylights, elevators, stadiums, zoos, bridges, curtain walls, as well as hundreds of other uses.

Superior capability, high Low-E tempering

TecnoBEND bent glass is available with tempered Low-E coating in architectural glass sizes. It is also possible to bend and temper a glass coating against the rollers. Bending is performed through gravity bending processes, by pressing the glass against rollers to assure high optical glass quality. We process flat glass in the bending section of the tempering line with a separate chiller.

Beyond new fabrication methods, curved glass also has benefited from the availability of more robust coatings and interlayers. While in the past coatings would warp when glass was bent, new proprietary technology allows us to curve glass while still maintaining its patterns and effects. The coatings and interlayers now available open up a number of new options for curved glass.
