Series 4400 Casement Project-In Windows

The Boyd Series 4400 is a commercial aluminum casement window that opens inward and combines a clean architectural appearance with high-performance construction for demanding commercial projects. Dual corner-key construction and an AW-PG100 rating make the Series 4400 a dependable choice for coastal applications, schools, universities, hospitals, government offices, military buildings, and other monumental projects.

The Series 4400 features a 4" main frame depth, an integral thermal barrier, and a choice of inside- or outside-set glazing up to 1.5" thick. Main-frame and sash construction uses application-specific .062" and .125" aluminum wall thicknesses, while true, interior, historical, and applied muntin options support contemporary, divided-lite, and restoration-inspired designs. Screens, blinds or dual glazing, multiple operating-hardware packages, perimeter accessories, finish selections, and project-specific customization options are also available.

When to Use the Series 4400 Project-In Casement

• Commercial openings requiring a side-hinged casement window that opens inward.

• Coastal applications where AW-PG100 performance, finish selection, corrosion-related requirements, and project-specific exposure conditions must be coordinated.

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

• Projects requiring a 4" thermal-break frame and inside- or outside-set glazing up to 1.5" thick.

• Openings requiring true, interior, historical, or applied muntins, screens, blinds or dual glazing, project-specific operating hardware, and coordinated interior clearance.

Choosing a Series 4300 or 4400 Operable Window

You are viewing the Series 4400 Project-In casement configuration. Review the related options below when the project requires outward casement operation or projected operation rather than side-hinged casement operation.

Series 4400 Project-In Casement Advantages

• AW-PG100 performance makes the Series 4400 a dependable choice for demanding commercial and coastal applications.

• Dual corner-key construction supports reliable operation in schools, universities, hospitals, government offices, military buildings, and monumental projects.

• A 4" thermal-break frame and inside- or outside-set glazing up to 1.5" thick provide specification flexibility.

• True, interior, historical, and applied muntin options support contemporary and divided-lite architectural designs.

• Applied muntin systems can permit glazing replacement without removing or replacing the applied muntins.

• Multiple operating-hardware packages allow project teams to coordinate hinges, friction control, lever handles, cam latches, push-pull handles, and custodial operation.

• Two rows of weatherstripping at the sash members support dependable air and water performance.

• Screens, blinds or dual glazing, panning, receptors, subsills, mullions, trims, finishes, and customization options support unique project specifications.

Common Series 4400 Project-In Coordination Items

• Project-in operation: Confirm interior clearance, opening angle, hardware package, screens, shades, furnishings, wall conditions, circulation paths, and other interior obstructions.

• Coastal exposure: Coordinate finish, corrosion-related project requirements, adjacent metals, fasteners, perimeter sealants, drainage, and maintenance expectations separately from impact performance.

• Glazing-set direction: Confirm inside- or outside-set glazing, glass makeup, overall thickness, safety-glazing requirements, glazing access, blinds, and dual-glazing requirements.

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

• Hardware and screens: Select the operating hardware package and confirm operator location, hinge type, handles, latches, friction control, screens, accessibility, custodial control, and maintenance access.

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