The roof of the British Museum Queen Elizabeth II Great Court, London, by Foster & Partners, completed 2000. The largest covered public square in Europe, the roof consists of 3,312 individual panels of glass - no two panels are the same - held within a triangulated steel lattice shell that acts both as primary supporting structure and framing for the glass. The toughened and laminated glass panes are screen printed with a dot matrix pattern (frit) to reduce solar gain.

Beijing Airport Terminal 3, designed by Foster and Partners and engineered by Arup, completed 2008, features louvres manufactured from extruded aluminium, mounted to a trussed steel roof structure
