Allianz Arena in Munich

  • When a match is on, the entire synthetic skin of the stadium lights up in red or blue, depending on which of the two home teams is playing
  • White light remains the option for games where no local teams are involved
  • The skin is divided up into diamond-shaped cushions
  • Behind there are different load-bearing systems- Cantilevered steel lattice girders from the primary structure of the roof, while the secondary support structure for the roof and vertical facades, structurally separate from the primary frame, is a rhomboid grid of steel girders, with field diagonals varying from 2×7 meters to 5×17 meters
  • The 65,000m2 skin is made up of 2,874 individual ETFE cushions, each one matched by only one other of identical geometry
  • The cushions are fixed in aluminum profiles that clamp the weather-strip edge to the secondary construction
  • The gutters between the cushions are sealed with flexible plastic profiles and welded at the junctions
  • Twelve air-pumping stations keep a constant internal pressure in the cushions, raising it as required depending on wind and snow loads.
  • The cushion “covers” are made of white ETFE
  • To avoid too much shading of the turf, the cushions on the southern part are fitted with transparent ETFE sheeting, which allows virtually all the UV portion of sunlight to permeate, thus giving good growing conditions for the grass
  • At night 1,058 facade cushions are lit up by fluorescent lights inside
  • Specially developed cover plates of acrylic glass act as a colour filter to create monochrome lighting or bi-colour stripes and diamond patterns
