I might need to go on a field trip to the Vikings’ new stadium…just to see these doors! WoW! Blake Nelson of Allegion sent me these photos from a recent site visit, and the news report from CBS Minnesota fills in all of the details.
Amazing!

Neat
Cowboy stadium must have sliding doors, which they hardly open just like the roof.
Must be hot in Texas??
Retractable end zone doors
− The 180-foot-wide by 120-foot-high operable glass doors, located at each end of the
stadium, are the largest operable glass doors in the world
− Five 38-foot panels take 18 minutes to open or close

BIG DOORS!
Whoa.
This is awesome.
Lori,
Travel to Arlington, TX and I’ll give you a tour of doors at Jerry World.
Dallas needs to have something to attract fans. The Cowboys sure aren’t anything to go see. LOL
Well, if you don’t have any Lombardi Trophies, you might as well have nice doors! GO PACK! 😛
The Irving / Arlington Cowboys have 5 Lombardi Trophies including back-to-back (1992-1993) and second only to Pittsburgh in number of wins.
Oh yeah, gotta make a pilgrimage just to watch these in operation up close! With your connections, Lori, are you able to dig up the specs for these, and maybe some up-close pix of details, e.g. pivots, operator, bolting, seals, etc? Also concerned how much windload they can withstand while standing open.
Thanks for posting!
I don’t have any intel, but maybe when the book comes out the author will include some detailed info on the doors. He seems to know how cool and unusual they are.

The strategy, I’m guessing, is to allow the HVAC system to shut-down and natural ventilation to take over on mild Minnesota days. At first, you think what a colossal cost for these doors, but so is the cooling bill for such a huge building. My guess is that they will not be opened in the cold of winter. It remains to be seen how the doors react to thermal expansion/contraction and ice. They probably have built-in heaters. I think they are amazing, and I’m sure the design team has considered all the criteria that goes into such an engineering feat. Thanks Allegion for sharing.
