Super Bowl 2019 under an ETFE film roof from Bavaria

The hearts of American football fans are set to beat a little faster again when the Super Bowl, the finale of the American pro football league, the NFL, is held on February 3rd!

The venue in 2019 is the Mercedes-Benz Stadium in Atlanta – a stadium of superlatives. In 2017, film specialist NOWOFOL from Siegsdorf played a decisive role in designing the state-of-the-art football stadium with an ETFE film roof and façade shell.

When the Los Angeles Rams and the New England Patriots face each other in the NFL’s 53rd Super Bowl on February 3rd, 800 million people around the world will be looking at a project by the Bavarian film specialist NOWOFOL. The roof construction made of ETFE film gives the football stadium in Atlanta a mobile and stable roof in an extraordinary design. The shape, which looks like eight flower petals, is reminiscent of the mechanism of a camera lens when opening and closing. The ETFE film roof made in Bavaria not only protects the 75,000 fans in the stadium from wind and weather but also looks absolutely stunning like the transparent façade elements made of ETFE film, it gives the stadium its inimitable look.

High-tech films enable extraordinary architecture

The fluoropolymer films made by the Bavarian manufacturer NOWOFOL are internationally popular for stadium constructions on a grand scale because they enable an exciting stylistic idiom with a low weight per unit area. The special films from Siegsdorf were also used for the Minnesota Vikings Stadium (Minneapolis), the Miami Dolphins Stadium and the bright blue stadium of Club Puebla in Mexico.

NOWOFOL’s film membranes are more flexible than traditional materials in terms of shape yet still offer excellent mechanical strength, weather resistance and high light transmission for unclouded daylight inside. Around 50,000 m² of ETFE film from Bavaria were used in the Mercedes-Benz Stadium in Atlanta.

Permanent innovation: Infrared-absorbent ETFE film

The film specialists at NOWOFOL are known for their high degree of innovation.  With an infrared-absorbent ETFE roof and façade membrane, a new global development is being offered on the market. The special film absorbs the infrared radiation to prevent excessive heating of the roofed space, which is a great advantage, especially in regions with warmer climates. This material is already being used successfully for the partial roofing of shopping centers. At the stadium in Atlanta, flexible shading was solved with printing.  Whether in subtropical summer heat or in rain and snow, the spectators in Atlanta can enjoy the event undisturbed. The printability of the ETFE films and the wide range of colors make the special films from Bavaria a favorite with architects and builders.

In addition to the use of ETFE films for roofs and façades of sports stadiums, shopping malls and swimming pools, demand is also growing in greenhouse construction due to their high tensile strength and high level of light transmission. Andreas Freutsmiedl, Sales Manager for Fluoropolymer Films, says: "ETFE film has a great future in greenhouse construction. The films currently used

for roofing in greenhouses last for only a short period of time and are destroyed by wind and weather. ETFE film is a rugged alternative. The first roofs with ETFE film have been in existence for more than 40 years, and the film is still in perfect condition. In addition, ETFE film is 100% recyclable after use.”

World market leader from Siegsdorf

NOWOFOL is one of the world’s biggest suppliers of ETFE film. This film has been produced at the company headquarters in Siegsdorf since 1982. NOWOFOL has 160 employees and is a real world market leader, not only in the production of UV stable ETFE films but also for monoaxially stretched polyolefin films. These extremely tear-resistant films are used in the packaging industry, in technical applications and other special solutions.
