Glazing triumph: the roof of Waterloo station in London. The boxy structure at bottom left of the picture is the recently-completed infill connecting the former Waterloo International trainshed in the foreground, now used by domestic services, and the station’s main concourse. Specialist contractor Prater fabricated a Schüco façade system at its Thurrock facility for the infill, consisting of a bespoke curtain wall glazing system and Prater-designed and fabricated glass louvres integrated into the façade to provide ventilation. Due to the potential threat of attack at this high-profile London landmark, one of the key performance requirements for the glazed curtain walling was strength and enhanced blast resistance.
