Knoxville is the seat of Marion County, known worldwide as the Sprint Car Capital of the World for its legendary dirt track raceway. The city features a well-maintained downtown square, established residential neighbourhoods, and a strong community identity tied to its racing heritage.
Knoxville's position in Marion County brings cold central Iowa winters with temperatures dropping below -10F and open terrain that amplifies wind exposure for homes throughout the community.
Knoxville's many older homes near the courthouse square and in established neighbourhoods have windows that are well past their service life. Iowa's extreme temperature swings demand better insulation than aging single or double-pane windows can provide, making triple-pane upgrades a smart investment.

Our home near the Knoxville square had ancient windows that made winter miserable. Panes installed triple-pane replacements and the difference is unbelievable. Warm in winter, cool in summer, and our energy costs dropped immediately. — Dale S., Central Knoxville
