Grinnell is a charming college town centered around the prestigious Grinnell College and a downtown that features the architecturally significant Merchants National Bank by Louis Sullivan. The city offers a mix of historic homes near the campus, established residential areas, and a vibrant intellectual community.
Grinnell's central Iowa prairie location brings harsh winters with temperatures dropping below -15F and powerful winds that sweep across the farmland, exploiting gaps in older window installations.
Grinnell's historic homes near the college campus include many properties with original windows from the late 1800s and early 1900s. These windows are beautiful but thermally inadequate for Iowa's brutal winters. Custom replacement windows preserve architectural character while providing modern energy performance.

Our historic home near Grinnell College needed windows that honored the architecture. Panes manufactured custom windows with period-appropriate profiles and modern triple-pane glass. The result is beautiful and our heating costs have dropped dramatically. — Emily W., College Hill
