What Quaker Window Products does
Quaker Window Products Co. is a family-owned manufacturer of aluminum, vinyl, and wood windows and doors founded in 1949 in Freeburg, Missouri, and still controlled by the founding Knoll family. The company operates three go-to-market divisions — Quaker Residential (new construction and remodeling windows and doors), Quartz Luxury Collection (premium residential), and Quaker Commercial (architectural and light commercial fenestration) — and produces approximately 2,500 window and door units daily across dedicated manufacturing facilities in Freeburg, Eldon, and Vienna, Missouri, with the Eldon campus scaling toward 800,000 square feet.
The product portfolio spans hung, sliding, casement, fixed, projected, and geometric-shape windows and terrace, sliding, French, folding, and entry doors, supported by proprietary technologies including the patented OptiCore thermal/structural/sound performance platform (winner of DWM Magazine's 2019 Reader's Choice Award) and SolidCore thermal barrier technology. Specialty offerings include B500 Series blast-tested windows certified to Department of Defense Minimum Anti-Terrorism Building Standards (ASTM F1642-04) and impact-rated systems for coastal markets introduced in the 2026 Product Collection. The company holds AAMA 2604/2605 paint certifications, EnergyStar partnership status, and is an active member of NGA, FGIA, and WDMA.
Quaker's business model is hardware sales through an indirect channel: residential products are sold via an authorized dealer network with a dedicated Q1 Partner Portal for ordering; commercial products are sold through a separate commercial rep network targeting architects; and luxury products are sold through specialist consultants. Pricing is quote-based and not publicly disclosed. The customer base is diversified across the residential replacement market, new construction builders, luxury custom-home projects, commercial architects, and government/military buyers, with no disclosed anchor customers and revenue distributed across the long tail of authorized dealers and project pipelines.
