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 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.
Panes Windows & Doors provides a full range of window and door services to homeowners and builders in Knoxville and the surrounding Central Iowa area. We offer new construction windows for builders working on custom homes, townhomes, and multi-family developments. Homeowners looking to upgrade can choose from our premium replacement windows designed for quick, clean installation with minimal disruption. In addition to windows, we supply fiberglass and steel entry doors to boost curb appeal and security, as well as sliding and multi-track patio doors that bring natural light into your living spaces. All products are available supply-only for contractors or with full professional installation by our experienced crews.
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. Our triple-pane and double-pane vinyl windows feature Low-E glass coatings, argon gas fills, and multi-chamber frames engineered to minimize heat transfer. This helps keep your Knoxville home comfortable year-round while reducing heating and cooling costs. Energy-efficient windows can also qualify for local utility rebates and federal tax credits, putting money back in your pocket.
