Great Glazing: Arena Corinthians
The basics: Located in Sao Paulo, Brazil, the glass-studded Arena Corinthians, the football stadium that hosted six games of the 2014 FIFA World Cup Brazil—including the opening game—features an original, modern design, heavily accented by extra-clear glass, selected for its aesthetic qualities for use in the façades, balustrades and VIP lounges. The arena’s architects wanted a design solution that offered exceptional transparency and color stability.
“As the home stadium of the Sport Club Corinthians Paulista, Arena Corinthians needs to incorporate the team’s colors, which are black and white,” said Anibal Coutinho, chief architect. “Following several tests, we determined…the ideal glass material for this historic architectural project for its rendering of purely white colors.”
The players: Architect, Coutinho Diegues Cordeiro, DDG Arquitetura; general contractor, Odebrecht; glazing contractor, Grupo Galtier; glass manufacturer, AGC Glass Co. Brazil; glass fabricator, Sunglass s.r.l.; steel frame and aluminum facade suppliers, Extrugasa, Eleve Metallic Constructions; glass coating technology, Diamon-Fusion International
The glass and systems: The arena uses a total of 72,000 square meters of glass weighing 1,500 tons. DDG Arquitetura architects chose AGC Glass Co. Brazil as an official supplier of the stadium upon favorable evaluation of its Planibel Clearvision float glass product. The specialty float glass provides exceptional clarity through minimal impurities, and its low iron content allows objects to be viewed in their original color and maintains an optimal color rendering when painted, AGC reports. Glass fabricator Sunglass s.r.l. designed the arena's facade glass with a curvature intended to simulate the visual effect of a ball hitting the net.
Special 26-meter seamless beams support the structure. The 58,125-square-foot double curved freeform glass surface is separated into 855 planar and cylindrical panels, all in hot tent toughened glass.
The project also utilized Diamon-Fusion coating on the stadium structure glass panels to protect the glass from harmful environmental elements, while helping to reduce the maintenance of the glass over time, Diamon-Fusion International reports.
