Laminated Glass Panels:

A factory in Vancouver, Wash., prefabricated the steel."  The glass weighs approximately 158 tons, 316,000 lbs total or approx 141 lbs per panel.

The glass panels were fabricated by Oldcastle Glass globe in Fremont, CA and Prelco Inc. in Quebec, Canada (can't find website for Prelco).  Here is an article pdf icon about how the glass panels were designed; the article comes from Solutia/Vanceva, the company who supplied the "interlayer" that goes between the layers of glass.   Solutia competes with DuPont in this area, see below for info from DuPont.
