Curved glass makes buildings flow.

The sleek and sophisticated appearance of glass offers unparalleled style, keeping it among the top material choices for everything from buildings to trophy cases. However, the newest glass design trend takes the modern appeal of glass and adds a twist. Curved glass is increasingly used to add movement and dimension to traditionally static structures.

Every year the demand for custom glass grows as architects and designers request curved or bent glass solutions for more dramatic designs. Tecnoglass has met this changing demand and provided glass solutions for creating innovative spiral staircases, skylights, elevators, stadiums, zoos, bridges, and curtain walls, among hundreds of others uses. Bent glass can make great architecture extraordinary.

Superior capabilities through Low-E tempering

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

Beyond new fabrication methods, curved glass also has benefited from the availability of more robust coatings and interlayers. While at one time coatings would warp when glass was bent, new proprietary technology allows us to curve glass and still maintain its patterns and effects. The coatings and interlayers now available open up a number of new options for curved glass. Nothing is off-limits: Anti-reflective coatings, dichroic coatings, semi-transparent mirror coatings, as well as insulating glass units, and glass with metal meshes or wood louvers.
