More than 130 Optimum Series HR-4500 hot-rolled steel project-in hopper, fixed picture and special shape cathedral arch transom windows were used to keep with the style of the chapel and theological administrative building.

"I am proud Optimum windows were selected as the replacement window for this magnificent historic building," said C.J. Perez, vice president of Optimum. "The use of our hot-rolled steel windows on this project maintains the building's truly historic design style, while providing 21st Century functionality and energy efficiency."

The Union Theological Seminary is affiliated with Columbia University, which also chose Optimum windows - the Elegance Series C55 -for a new dormitory nearing completion, according to the news release.
