Aluminum Windows in York, PA

Western Window Systems designs and manufactures aluminum moving glass walls, window walls, doors, and windows for projects that emphasize indoor-outdoor living, broad glass openings, and modern sightlines. The brand is especially visible in contemporary residential, hospitality, and light commercial work where large panel sizes, narrow frame profiles, and integrated door-window systems are central to the design. Founded in Phoenix in 1959, Western Window Systems built its reputation around expansive sliding, folding, hinged, and fixed glass systems. Its current product catalog includes Classic Line and Vantage Line systems, with multi-slide doors, sliding glass doors, bifold doors, pivot and hinged doors, fixed/window wall assemblies, and complementary operable windows. Western Window Systems is part of the MITER Brands portfolio following MITER Brands' 2024 acquisition of PGT Innovations. For specifiers, the company is most relevant when a project needs large aluminum openings, coordinated door and window families, and product data for custom residential or commercial-style fenestration packages.
