The Silver Blue slate served a dual purpose for the project design - its color not only contrasts with the grayish-green quartzite, but it also blends with other elements specified for the project. "The [slate] ties in with the color of the charcoal gray leather panels on the walls of the elevator bank in the lobby," said Pacior.
The slate was used to replace the existing wood panels for the "identity wall," which features the building's address. In addition to the color and aesthetics of the slate, the material was chosen for its texture. The stone, which is cleft finished, has a natural "rough" texture to it, explained Pacior, adding that approximately 400 square feet of slate was used for the identity wall in 12- x 24-inch thin-set tiles.
