Series 6400 Historic-Replica Casement Project-Out Windows

The Boyd Series 6400 is a commercial aluminum historic-replica casement window that opens outward and combines classic steel-window character with modern commercial performance. Its dual corner-key construction, narrow historic appearance, and project-out casement operation make it a strong choice for restoration, adaptive-reuse, renovation, and replacement projects requiring careful historic review.

Boyd engineers the Series 6400 to meet AW-PG100 performance requirements while supporting the architectural demands of schools, military buildings, government offices, universities, hospitals, and other monumental applications. The system features a 3.25" main frame depth, thermal barrier protection, a combination of .062" and .125" aluminum wall thicknesses across the assembly, and a choice of inside- or outside-set glazing up to 1" thick.

When to Use the Series 6400 Project-Out Casement

• Historic restoration, adaptive-reuse, renovation, or replacement openings requiring a side-hinged casement window that opens outward.

• Projects requiring a classic steel-window appearance with modern commercial aluminum construction and insulated glazing.

• Schools, military buildings, government offices, universities, hospitals, and other monumental applications.

• Operable openings requiring AW-PG100 casement performance, a 3.25" frame depth, and inside- or outside-set glazing up to 1" thick.

• Historic-review projects where profiles, sightlines, muntin patterns, glazing configuration, hardware, and finish must be coordinated with the existing building.

Choosing a Series 6200, 6300, or 6400 Historic Window

You are viewing the Series 6400 project-out casement configuration. Review the related Series 6200 fixed and Series 6300 project-out systems below when the project requires a non-operable opening or projected operation rather than side-hinged casement operation.

Series 6400 Project-Out Casement Advantages

• Historic-replica aluminum construction recreates classic steel-window character while supporting modern commercial performance.

• Dual corner-key construction supports demanding monumental, institutional, and historic-review applications.

• AW-PG100 performance with a thermal barrier, 15 psf water resistance, and 150 psf structural performance.

• Choice of inside- or outside-set glazing up to 1" thick supports project-specific detailing.

• True, interior, and historical muntin options support original divided-lite patterns and steel-window appearance.

• Applied muntin systems can permit reglazing without grid removal when specified for the selected configuration.

• Screens, panning, receptors, subsills, mullions, trims, and multiple hardware packages support project-specific operation and installation requirements.

Common Series 6400 Coordination Items

• Historic review: Coordinate existing profiles, sightlines, sash proportions, muntin pattern, glazing character, finish, and required documentation with the architect and reviewing authority.

• Project-out casement operation: Confirm exterior clearance, opening angle, hardware package, screens, adjacent walls, walkways, landscaping, and other exterior obstructions.

• Glazing-set direction: Confirm whether the project requires inside- or outside-set glazing, the glass makeup, overall thickness, safety-glazing requirements, and reglazing access.

• Muntins and divided lites: Coordinate true, interior, historical, or applied muntin construction, grid pattern, lite divisions, attachment method, and visual alignment.

• Fixed and projected coordination: Coordinate the Series 6400 with adjacent Series 6200 fixed or Series 6300 project-out windows where the elevation combines multiple operating types.

• Openings and accessories: Verify field dimensions, substrates, anchors, panning, receptors, subsills, mullions, trims, sealants, drainage, and surrounding construction before release.
