Full Spectrum Stained Glass was pleased to be selected as the stained glass contractor for the University of Michigan’s prestigious Law School Renovation Project converting an existing courtyard into the Robert B.Aikens commons with the addition of a Glass Roof and a new bridge between Hutchins Hall and the North Tower. Full spectrum’s scope included new leaded glass for windows, door panels, sidelights, transoms and a Donor Recognition Wall; conservation, repair, relocation and restoration of steel frame casements and stone-set historic leaded glass windows. A unique part of the project illustrated below involved adding Fire Rated glass to four original stone-set windows while preserving the historic leaded art glass.

Removal of the Architectural Art Glass was completed by Full Spectrum staff during the early stages of the demolition phase. Blocking was provided as winter protection after removal.


Following removal of the art glass in the tracery and lancets casement windows were remove from the registers and demolition of limestone mullions began.


The complete Limestone window surround (mullions and perimeter) was removed and discarded from all four windows. Sills and knee walls were also removed from the two center windows to accommodate new entry doors between the Cloister and the new student commons.


After demolition of the windows was completed steel was set in the openings to receive the Fire Rated Glazing provided by Edwards Glass Livonia, Mi. The next step was fabrication of new limestone window surrounds for both sides of the Fire Rated Glazing.


Leidal & Hart Mason Contractors Livona, MI and Bybee Stone, Ellettsville, IN adeptly handled the challenge of creating complete mirror image limestone surrounds in four window openings. Two separate surrounds were required in each window, one to accommodate the original art glass on the Cloister side and the other to accept new leaded panels fabricated by Full Spectrum on the student commons side of the fire wall. The photo (left) taken from the Cloister Side with its limestone mullion in the forefront, fire rated glass and mullion being drilled on the commons side illustrates the unique design used by Hartman Cox Architects, LLP to preserve the Architectural Leaded Glass.



Above steel casement frames salvaged from the two center windows and replicated leaded glass panels are installed to restore the windows to their original appearance from commons side.


As with all project Full Spectrum’s dedicated staff see to every detail during the installation of the restored original art glass panels. The new limestone window surrounds on the cloister side of the wall received the original restored steel casement frames and leaded panels with no changes to the size or shape.



The completed project is a testimony to the good communication and coordination skills of the University Of Michigan AEC, architects Hartman Cox, construction managers Walbridge, and many skilled tradesman that participated in this unique project.
