About Windsor Windows & Doors
Windsor Windows & Doors is a Storm Lake, Iowa manufacturer of wood, clad-wood, and composite window and door systems for the residential market. Founded in 1946 as Windsor Window Company, the brand built its reputation on hardwood window construction and precise joinery — products oriented toward regional custom builders, architects, and replacement contractors in the Midwest and upper Great Plains. Windsor is now a subsidiary of Quanex Building Products, the Houston-based fenestration components manufacturer that acquired Windsor in 2014.
The Windsor product line spans aluminum-clad wood and wood interior double-hung, casement, awning, fixed, picture, and specialty window configurations, alongside sliding and hinged patio door systems. The Revere and Legend product families represent Windsor's primary residential offerings, covering varying combinations of sash material, exterior cladding, and performance level. Windsor windows are positioned as a mid-to-upper-tier residential option, appropriate for custom homes, renovations, and new construction where wood interior appearance, regional dealer support, and an alternative to national brands are valued.
For specifiers in the Midwest and upper Great Plains, Windsor offers dealer relationships and regional distribution infrastructure that supports competitive lead times and accessible service. Clad-wood construction provides the wood interior warmth preferred in custom residential work while aluminum exterior cladding reduces long-term maintenance relative to fully exposed wood. Specification should begin with confirmation of available glass packages, cladding colors, and lead times through a local Windsor dealer.
