Curved glass comes in 3 main types, annealed, toughened and laminated, toughened curves can also be laminated together and combinations of curves can be sealed into double glazed units.
Annealed glass bending
Annealed bends are manufactured from raw material flat glass, either float, patterned, wired, tinted and even self-cleaning glass. The actual curve is produced by applying heat to the flat glass which softens and adopts the shape of a mould which has been produced from template or a CAD drawing. Holes, cut outs and notches are possible. Annealed bends can be used in single glazed or double glazed applications where safety is not an issue.
Using two matching annealed bends, laminated bends are created by edge taping the 2 bends together and then injecting or pouring a resin laminate between the glasses and allowing it to cure. Once cured the bends are permanently laminated together and form a safety glass.
Applications: Shop fronts and revolving doors, screens, partitions, canopies and cabinets, as well as components for double glazed units, indeed any area where impact resistance is required. Also available on the thinner glasses is an acoustic laminate for areas where noise reduction is an issue.
Toughened curved glass is produced from annealed glass which has been heated and then cooled rapidly. This introduces stress into the glass surface which strengthens the glass. Once subjected to impact or thermal stress, toughened glass breaks into small blunt fragments which reduce the possibility of injury. Applications: infill balustrade panels display counters, partitions, canopies, balconies, curved reception desks, as well as components for curved double glazing and curtain walling.
Express bend service
Most replacement glazing is in laminated form. As curved glass manufacturers we can provide replacement bends within one week of receipt of either template or CAD drawing.
