Roissy-Charles de Gaulle, France
Aéroport de Paris
Architect: Paul Andreu
The most recent addition to infrastructures at Charles de Gaulle airport is terminal 2F: a long concrete vault extended by two ‘peninsulas' with which aircraft come into direct contact. Profiled glazing dresses out the vault's sides and gives the departure lounges enclosed there excellent light. The structure that carries the glazing is composed of a succession of steel trusses that comprise a straight chord and a curved double rod, triangulated by oblique braces and rods to ensure light weight.
Strain is absorbed in the upper part by a caisson-beam that rests on the vault structure, and in the lower part by an anchor shoe that looks like half a bicycle wheel set in a concrete base. Perforated stainless steel sun-breakers, set away from the glazing, afford protection from direct sunlight. The unusual geometry of the ‘peninsulas' benefits from technical solutions that are both simple and refined; the result is an exceptional space.
