Here is another stick system installation around 30th and 6th Ave in Manhattan. We can see the thermal break and interior gaskets exposed on the aluminum mullions, anticipating the installation of the insulated glass units and the pressure plate and cover. Steel angles anchor the mullions to the concrete spandrel beam. Shims are visible between the steel angle and the concrete beam.

The exterior wall above for the tower appears to be a window wall, likely installed as a unit system. The curtain wall system at the base spans from the sidewalk to the ceiling of the second floor.
