ETFE foil extendable panel and other materials
Deflated panel: 9' 10 1/8" x 6' 2 13/16" (300 x 190 cm); fully inflated panel : 32' 9 11/16" x 15' 1 1/8" (10 m x 460 cm)
Nicknamed “ring of fire,” the Allianz Arena, designed for Munich’s two local soccer teams, features an outer membrane constructed of 2,874 inflated ETFE foil panels. Each panel contains four lights that can be illuminated in white, red, or blue, so that the panels can be independently lit with the colors of the home team. The stadium glows red for FC Bayern München, blue for TSV 1860 München, a checkerboard when they play each other, and white for the German national team or other matches. Thus the arena wears the team colors, embodying and magnifying the energy of the spectators inside it.
