The 80-year old neo-classical style Smith Hall, part of Rockefeller University in Manhattan, recently underwent a major restoration that included the installation of several hundred large heavy-commercial aluminum windows. The window replacement, supplied by Crystal Window & Door Systems, is part of ongoing work also involving the restoration of an adjacent building and the construction of a new “bridging” building to join the two into a new Collaborative Research Center (CRC). The Rockefeller University CRC project is registered with the U.S. Green Building Council and is pursuing Leadership in Energy & Environmental Design (LEED NC 2.2) certification. The construction manager for the Smith Hall restoration is Turner Construction.

Crystal supplied Rockefeller University’s Smith Hall project with 300 heavy-commercial rated Series 6000 double-hung aluminum windows. The Series 6000 has an AAMA rating of H-HC65 and features heavy-duty thermally broken 4-¼ -inch frames and 1-inch insulating glass units with special glazing for superior energy efficiency.

The project windows were tall, with some exceeding 8-½ feet in height.

Special ultra-lift balances were included to aid in operating such large sashes.

Crystal also provided historic panning to facilitate the installations and preserve the building’s original window appearance. All the windows and panning systems were finished with a high-performance historic “Galapagos Green” color 70 percent Kynar paint meeting AAMA 2605 specifications for durability.
