Crystal Windows Installed in Historic St. Louis Area Building

July 6th, 2012 by Editor

Crystal Window & Door Systems supplied more than 1,100 new energy-efficient windows for the rehabilitation of the historic Castle Park Apartments complex in Normandy, Mo., which recently celebrated its grand re-opening.

The 200,000-square-foot, 4-story castle-like structure was completed in the 1890s as a Catholic sanatorium hospital for the mentally ill. Following many decades as a hospital, the property was sold and the building was converted into apartments in 1982. In 2007 a Denver-based non-profit affordable housing developer began a $27 million acquisition and redevelopment effort, which called for significant interior and exterior restoration including new windows.

Crystal supplied 966 Series 5000 aluminum double-hung windows and 176 Series 2100 aluminum picture windows. Both aluminum window models feature 3¼-inch energy efficient frames and ⅞-inch insulating glass units with Solarban 60 low-E coating and argon gas filling. The windows are finished with a powder coat bronze color paint.

The historical nature of the project presented Crystal with some additional requirements and challenges. An exterior applied grid frame was installed around the glass perimeter of each new window sash to replicate the look of an historic putty line glazing bead. On the new picture windows, a 2-inch applied exterior horizontal muntin was used to mimic the building’s original double-hung windows. Crystal also developed special window frame extrusions which eliminated the screen track, as required by the historical specifications.

Adding a local touch to the window project, the aluminum window frame material was provided by Crystal’s aluminum extrusion subsidiary in nearby Union, Mo., and the sale was coordinated by Crystal’s Fenton, Mo., branch. The windows were installed by Dalco Remodeling’s Commercial Division of Bridgeton, Mo.
