Steel Window Restoration, Aluminum Window Replacement
Kalamazoo, Michigan

Originally the Kalamazoo Trust and Savings Bank, constructed in 1929–30. The 23-story building was designed by Chicago architects Weary and Alford who also designed the Kalamazoo City Hall. At the time of construction it was the tallest building in Kalamazoo.

The building has an exterior of Indiana Limestone and features an Art Deco Design. Ornamented archways with geometric banking and nature motifs surround all the doorways and windows on the first three floors. The interior boasts vaulted ceilings and the interior atrium was hand-painted in a pastel Egyptian theme by Otto Stauffenberg, a local artist. The building was added to the National Register of Historic Places in 1983.

BlackBerry was involved with two phases of work, first the replacement of all windows from the 3rd through 23rd floors, and second the restoration of the 1st and 2nd floor lobby windows. The existing windows were causing water penetration and air infiltration issues for the building tenants. BlackBerry restored all of the lower floor steel windows, including asbestos and lead abatement.

All frames were stripped, cleaned, epoxy patched, and re-glazed with 1” high performance insulated glazing, and painted with a high durability finish. The upper floor windows were replaced with a thermally broken fixed aluminum window, replacing the existing pivoting sashes. All site lines and profiles were replicated providing an energy-efficient historic aluminum window replication and restoration.
