Description

Bent or curved glass is processed flat glass that has been formed into cylindrical, spherical, or complex curved shapes through controlled heating and forming processes. Available in thicknesses from 6mm to 19mm, bent glass can be produced as annealed, heat-strengthened, toughened, or laminated products. The material offers architectural flexibility for creating dramatic curved facades, glass balustrades, shopfronts, and specialty applications whilst maintaining the optical and performance properties of flat glass.

Primary Sectors

Glass bending techniques date back centuries, with early artisans using primitive kilns and moulds. Industrial curved glass production began in the 19th century for architectural applications. Modern bent glass manufacturing evolved significantly in the 1960s with the development of sophisticated bending furnaces and computer-controlled processes. Australian manufacturers like Bent and Curved Glass have been producing architectural curved glass since the 1970s, with recent advances in cold-bending techniques and bent-tempered glass expanding design possibilities. The AS 1288 standard has evolved to include specific provisions for bent glass applications, with the 2021 revision providing updated guidelines for curved glass in bushfire-prone areas.
