Series 400 Aluminum Fixed Windows

The Boyd Series 400 is a commercial aluminum fixed glass window engineered to create a cohesive appearance in buildings that combine fixed and operable window systems. Its dependable, high-performance design is well suited for hotels and motels, nursing homes, apartments, schools, hospitals, government buildings, and other commercial or institutional applications.

Reliable under harsh conditions, the Series 400 is AAMA tested to CW-PG100 and features thermal barrier protection, a 2.375" main frame depth, and bead-glazed insulated glass up to 1" thick. Interior and historical muntin options, coordinated accessories, and Boyd finish selections help project teams maintain a consistent fixed-to-operable appearance across contemporary replacement and new-construction projects.

When to Use the Series 400 Fixed Window

• Fixed, non-operable openings that must coordinate visually with adjacent Boyd operable window systems.

• Projects requiring CW-PG100 fixed-window performance, thermal barrier protection, and insulated glazing up to 1" thick.

• Replacement and new-construction projects where reliable performance under harsh conditions is a key requirement.

• Openings requiring interior or historical muntins, coordinated finishes, panning, receptors, mullions, trims, or other perimeter accessories.

Choosing a Related Fixed or Operable Window

You are viewing the higher-performance Series 400 fixed configuration. Review the related Series 450 fixed, Series 300 single-hung, or Series 600 horizontal sliding systems below when the project requires a more cost-effective fixed option or an operable window with the same 2.375" frame depth.
