Sports stadiums are notorious for their statement design and standing out from the surroundings. However, they must also have world class facilities as well as being comfortable and safe for spectators.
Allianz Arena in Munich, the home of Bayern Munich, is one stadium in particular where striking features and function are not comprimised.
Sunlight is essential for the growth of natural turf in the stadium, but because Munich is located at high latitude, the sun slants through the arena. Therefore, a material that could protect the 75,000 spectators from the elements, but still allow the penetration of sunlight in order to help the turf grow was needed.
Architects enlisted the help of ETFE, a plastic usually found in air and spacecraft to meet the needs of the stadium.
ETFE resins are resistant to ultraviolet light, which protects the fans in the stadium from the sun. The light transmission of ETFE is more than 90%, which invites the natural light to the turf in the stadium, helping it to thrive.
