Over time the operable ventilator sashes of these two windows became problematic and, at the suggestion from a glass studio, were changed from the original galvanized steel units to anodized aluminum. In the process the vent layouts were compromised; original glass was dramatically cut, signatures lost, and lightweight vents were improperly installed. Unfortunately the new vents did not resolve the problem but rather exacerbated it. The new vents did not open properly since they were unable to support the weight of the glass above them.
Newly designed operable vents based on the originals were fabricated by Studio del’ Arte of Brooklyn, NY. All original Tiffany glass was retained and replacement glass from the previous repair was discarded. New layouts were created from similar Tiffany window designs in the absence of period photographs that allowed the glass to regain its full dimension once again.
