Series 450 Commercial Fixed Windows

The Boyd Series 450 is a cost-effective commercial aluminum fixed window for replacement and new-construction projects. Boyd believes fixed windows should be as attractive and functional as today’s operable window styles, so the Series 450 uses modern design principles to support a cohesive contemporary appearance across hotels and motels, nursing homes, apartments, schools, hospitals, government buildings, and other commercial applications.

For dependable performance, the Series 450 features bead-glazed insulated glass up to .75" thick, a 2.375" main frame depth, thermal barrier protection, and an HC-40 AAMA rating. Interior glazing, interior muntin options, coordinated accessories, and Boyd finish selections give project teams practical flexibility for fixed-window replacement and new building designs.
