Project Details

The original hot-rolled steel windows with leaded glass on the east & north elevations were not replaced. It was extremely important therefore for the new windows on the west & south elevations to match the old while providing the thermal efficiency required by energy codes.

To accomplish this we chose Crittall’s Berkeley Range. It provided a solid steel beveled perimeter against the glass mimicking the putty glazing of the old windows. The Berkeley’s large glazing pocket also allowed us to use a bespoke true leaded 13/16” thick insulated unit which employs a leaded laminated outboard lite and interior Low E lite that is hermetically sealed.

The existing steel windows were relatively small in size and operation was by means of single or side-by-side casements. To maximize daylighting and the owners’ request for fresh air, the new Berkeley windows were designed much larger and operation was by means of double or “folding” casements, which when opened do not have a center stationary vertical post as the old windows do.
