High-performance glass and glazing renovate Wolverine’s stadium

"As people approach the stadium from the exterior they will see that it has been transformed to what most would interpret as a coliseum feel. The placement of our 1600 Wall System 1 curtain wall units in the brick punched openings around the perimeter was key to the design strategy. On the field side, the segmented and inverted sloping 1600 Wall System 2 curtain wall helps to update the stadium with a fresh new look and modern appeal as it provides a clean glass façade for the owners' added floor space."—Gerry Portelli, Kawneer territory sales manager.

The basics: University of Michigan's Wolverines started its 2010 season with a newly renovated stadium that features high-performance curtain wall and framing systems, entrances and windows.
