Guardian Industries Corp recently completed a long-term donation of glass to help the Ford Piquette Avenue Plant in Detroit restore its windows. The last shipment of glass from Guardian's Carleton, Michigan float plant will help workers finish more than 350 windows in the national historic landmark, all of which needed critical repair and restoration. The relationship between Guardian and the Ford plant began in 2011 after a Guardian employee attended an event at the site and saw an opportunity to help. The plant is the first building owned by Ford Motor Co. Eight different models were produced there between 1904-1910, culminating with the world-changing Model T. A volunteer work crew, named "The Window Team, is rebuilding each window by hand, using Guardian glass, in its own factory on the second floor of the Piquette Plant.
