Glass mullion system is a glazing system in which sheets of tempered glass are suspended from special clamps, stabilized by perendicula stiffeners of tempered glass, and joined by a structural silicone sealant or by metal patch plates.[1]
Buildings employing this system include the Rose Center for Earth and Space, Harvard Medical School inBoston, MA, NASDAQ Marketsite in New York and the Brooklyn Museum of Art.[2]
Of particular interest is I.M.Pei's National Airlines Sundrome at JFK Airport (Terminal 6) for its use of glass mullions, unprecedented at the time. The airline terminal is now closed and slated for demolition.[3]
