East Rutherford, NJ - MetLife Stadium, home to Super Bowl XLVIII is distinguished by an outer skin of aluminum louvers and by interior lighting that switches colors depending on which team is playing at home--blue for the Giants and green for the Jets.
This is a technique originated at the Allianz Arena in Munich, Germany which is shared between the city's two major Football clubs, Bayern Munich and 1860 Munich.
Unlike Giants Stadium, MetLife Stadium can easily be converted from a Giants game to a Jets game or vice versa within a matter of hours.
The special louvers and the associated hanging system were custom designed and manufactured by Overgaard Ltd. of Hong Kong and Architectural Wall Systems of Des Moines, Iowa.
The total linear length of louvers is exactly 50,000 meters (50 kilometers) or 163,681 feet (31.1 miles).
