This article takes a look at one of the most recent applications of SentryGlas, DuPont's interlayer for laminated glass. A visual highlight of the Champalimaud Foundation's recently-completed facility in Lisbon, Portugal, is the lightweight steel and glass bridge that connects its two buildings. The glass envelope encasing the bridge consists of curved panels of laminated glass made with DuPont SentryGlas interlayer, specified by the structural engineers Schlaich Bergermann und Partner and the specialist contractor Bellapart on the basis of its decreased deflection and superior post breakage behaviour as compared to laminates made with PVP. Moreover, the proximity of the building to the sea meant that the excellent weathering and durability performance of laminates made with SentryGlas were further criteria for their selection.
