The Vikings Stadium to be built in the Minneapolis city center will boast the world's largest transparent roof. The roof will be constructed using state-of-the-art ethylene tetrafluoroethylene (ETFE) instead of glass to handle the climate. Minnesota isn't an ideal place for a sport like football or other outdoor games because of its climate, but the new stadium will make it possible to host outdoor games. The stadium will host 65,000 sports fans and is expected to be constructed with a budget of $975 million.
The biggest attraction of the stadium will the the world's largest transparent roof. The roof itself won't open, but has been sloped to improve the load bearing capacity. The ethylene tetrafluoroethylene (ETFE) polymer allows more light to pass through it than traditional glass and weighs just 1% of the glass. This would make it ideal choice of material to use for constructing the roof. The polymer costs 24-70% less than glass and can hold 400x its own weight.
Another big advantage of ETFE is that it can be easily repaired by welding. The engineers say that the overal life of the polymer is approximately 50 years. Check out following fly-through video of the stadium which is soon going to be an engineering marvel.
