Kolbe Windows Contribute Architectural Integrity to Renovation

Monday, January 30, 2012

The University of Minnesota’s historic Folwell Hall completed a $49.5 million renovation resulting in a more comfortable, energy-efficient interior that preserves the exterior’s classically-collegiate character. Contributing to this delicate balance, Kolbe provided nearly 500 traditionally-styled, high-performance, low-maintenance windows in 16 different sizes and custom “Folwell” finishes.

Miller Dunwiddie Architects and McGough Construction guided the 127,700-square-foot interior renovation while respecting the vision of Clarence H. Johnston, Sr., the 1907 architect-of-record. The building’s century-old wood windows had been replaced in the 1980s with a basic, aluminum system, which hid some of the historic, architectural details. The replacement system integrated Kolbe’s aluminum-clad wood windows with custom, aluminum panning to replicate the original, architectural vision.

National Window Associates, Inc. selected Kolbe’s Ultra Series Sterling double hung units with standard LoE2-270 double-pane insulating glass to meet the University’s requirements and Minnesota Sustainability Buildings 2030. Under these guidelines, both new construction and major renovations must exceed the state energy code by at least 30%.
