The massive federal building sits at the corner
of Cadman Plaza East and Tillary Street in downtown Brooklyn. The
project consisted of historic replication of existing sash, and the
restoration of existing sash. Each sash was retrofitted to accept
insulated glass units. The weatherstripping system was changed, along
with performing Dutchmen and epoxy repairs on the sash and frames.
These changes provided the client (the GSA) with a window system that
was usable, efficient, and durable.
