Series 300 Commercial Single-Hung Windows

Boyd's Series 300 is a versatile, cost-competitive commercial aluminum single-hung window designed for new construction and retrofit projects. Its thermally broken construction and compact 2.375" main frame make it an excellent choice for hotels and motels, nursing homes, apartment complexes, multifamily buildings, and other commercial applications requiring dependable lower-sash ventilation.

Tested to CW-PG35, the Series 300 features a side-loaded operating sash that can be removed from the interior, heavy-duty block-and-tackle balances, a continuous integral lift, and a durable offset lock with a concealed or integral keeper at the meeting rail. Interior bead glazing accommodates insulated glass up to .75" thick, while interior or applied muntins, screens, coordinated perimeter accessories, finish selections, and project-specific customization support a wide range of replacement and new-construction conditions.

When to Use the Series 300 Single-Hung Window

• New-construction or retrofit openings requiring a cost-competitive, thermally broken commercial aluminum single-hung window.

• Projects requiring CW-PG35 performance, a compact 2.375" frame, .75" insulated glazing, and a removable operating sash.

• Traditional single-hung elevations requiring a fixed upper sash, vertically operating lower sash, and controlled lower-sash ventilation.

• Replacement projects requiring field-verified openings, panning, receptors, subsills, nailing fins, trims, or other perimeter accessories.

• Openings requiring interior or applied muntins, removable screens, finish options, and project-specific customization.

Choosing a Boyd Single-Hung, Double-Hung, or Fixed Window

You are viewing the Series 300 cost-competitive single-hung window for new construction and retrofit work. Review the related Boyd systems below when the project requires higher single-hung performance, historic-replica positioning, double-hung operation, a deeper frame, thicker glazing, or matching fixed openings.

Common Series 300 Coordination Items

• Single-hung operation: Confirm the fixed upper sash, operating lower sash, lift and lock locations, balance selection, operating force, user access, and any opening-control requirements.

• Egress and clear opening: Hotel, motel, apartment, multifamily, nursing-home, or sleeping-room openings may require emergency escape and rescue review. Provide net clear opening, minimum clear dimensions, sill height, unit size, and authority-having-jurisdiction requirements.

• Replacement openings: Verify field dimensions, existing frame conditions, demolition limits, interior and exterior returns, panning or receptor requirements, sill drainage, and installation access.

• Glazing: Confirm insulated-glass makeup, overall thickness up to .75", safety-glazing requirements, coatings, spacers, interior bead-glazing access, sealants, and current project thermal criteria.

• Muntins: Coordinate interior roll-form or applied simulated muntins, grid pattern, lite divisions, profile, attachment method, finish, and reglazing requirements.

• Sash removal and screens: Preserve interior access for operating-sash removal, cleaning, balance or lock service, screen removal, and glazing replacement.

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