Description of Work
This 1920’s historical condominium in the downtown area has a wonderful view.  However, the tired old jalousie windows chopped up the views and were very energy inefficient.

 Since this corner penthouse unit is located on the Seventh (7) floor of the building the trick in removing and replacing the windows required a specialty installation method.  Due to the location of the condominium, condominium building restrictions and the wind load codes we had to consider alternative installation methods.  Installation from the exterior presented horrendous scaffolding and safety problems.  The inside solution required a system that would be sealed and impervious to air and water.  Our choice was to use a Pella “T Frame sub system” to meet both requirements allowing the change out to work from the interior.  This metal frame system was applied to the opening sides after the old window was removed and the new window is sealed fixed to the frame last, very similar to a northern skyscraper system. 

 As part of this remodel of the view, three new windows on the western porch had arches applied to the windows in the field, manufactured on site, as the supplied arch muttons were only part of what was needed.  In the eastern porch, the original arched double hung windows were removed, dipped, stripped, glazed and installed to maintain the original appearance.  This wall was also partially rebuilt due to water rot.  Trim out of all the windows was a combination of wood casing and aprons and marble sills. 

As one can see the former average view became magnificent with the new windows and this 1920’s historical condominium is now more energy efficient.
