United Window & Door manufactures vinyl windows and doors from its base in Springfield, New Jersey. Founded in 1988 by brothers-in-law Howard Rose and Nick Derrico, the company draws on four generations of fenestration expertise within the family. It serves residential, commercial, and mixed-use sectors through authorized dealers and distributors across the northeast, and into several southern and midwestern states.
The company produces vinyl windows and doors for both new construction and replacement applications. Its technical capabilities span vinyl extrusion, coextrusion, and color bonding processes. A notable offering is its Onyx Black Acrylic Coextrusion technology, which the company claims delivers the most permanent color bond available in black vinyl windows whilst maintaining lead times equivalent to white products.
United Window & Door characterises itself as the largest and fastest-growing regional manufacturer of vinyl windows and doors in the United States, and claims to offer the most complete line of new construction and replacement products in its category. The company describes an emphasis on innovation and craft refinement rooted in its family heritage.
