Series 800 Aluminum Single-Hung Windows

Boyd's Series 800 is a high-performance, thermally broken commercial aluminum single-hung window engineered for heavy-commercial use and demanding conditions. Available in architectural configurations, including historic window replacement versions, the Series 800 is an excellent choice for historic building preservation projects, government buildings, military offices, schools, universities, and other institutional applications.

Tested to CW-PG50, the Series 800 features a 4" main frame, double-weatherstripped sash construction, heavy-duty spiral or Ultra-Lift balances, and custodial-key-operated tilt mechanisms for controlled interior cleaning access. Continuous perimeter marine glazing accommodates insulated glass up to 1" thick, while hospital-sill options, interior and applied muntins, screens, coordinated perimeter accessories, finish selections, and project-specific customization support unique preservation, renovation, and new-construction requirements.

When to Use the Series 800 Single-Hung Window

• Heavy-commercial openings requiring a thermally broken aluminum single-hung window for demanding conditions.

• Historic building preservation, historic window replacement, renovation, or institutional projects requiring a traditional fixed-upper-sash and operating-lower-sash appearance.

• Government buildings, military offices, schools, universities, and other commercial or institutional applications.

• Projects requiring CW-PG50 performance, a 4" frame, 12.11 psf water resistance, and marine glazing up to 1" thick.

• Openings requiring custodial-key-controlled tilt access, heavy-duty balances, interior cleaning, and tamper-resistant operation.

• Hospital or institutional openings that benefit from a hospital-sill option, screens, muntins, perimeter accessories, finish options, and customization.

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

You are viewing the Series 800 heavy-commercial single-hung window. Review the related Boyd systems below when the project requires higher single-hung performance, a different historic-replica configuration, double-hung operation, a shallower frame, or matching fixed openings.

Series 800 Single-Hung Window Advantages

• High-performance, thermally broken, heavy-commercial system designed for demanding conditions.

• Architectural and historic window replacement configurations for preservation, renovation, and institutional projects.

• CW-PG50 performance with 12.11 psf water resistance and 75.19 psf structural performance.

• A 4" thermal-break frame and continuous perimeter marine glazing accommodate insulated glass up to 1" thick.

• Tamper-resistant, custodial-key-operated tilt mechanisms provide controlled interior access for cleaning.

• Heavy-duty spiral or Ultra-Lift Class 5 balances support dependable lower-sash operation.

• Double weatherstripping at critical sash and frame interfaces supports reliable air and water performance.

• Hospital-sill, screen, muntin, panning, receptor, subsill, mullion, trim, nailing-fin, leg-extender, finish, and customization options support complex project conditions.

Common Series 800 Coordination Items

• Historic replacement and architectural requirements: Coordinate existing-window profiles, sightlines, sash proportions, meeting-rail location, muntin pattern, finish, perimeter conditions, and reviewing-authority comments.

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

• Custodial tilt access: Coordinate key control, authorized-user access, interior cleaning clearances, furnishings, shades, security, and maintenance procedures.

• Hospital sill: Confirm whether the project requires limited lower-sash opening without a daylight opening at the sill, along with intended ventilation and institutional safety requirements.

• Egress and clear opening: Where emergency escape or rescue requirements apply, provide required net clear opening, minimum clear dimensions, sill height, unit size, and authority-having-jurisdiction comments.

• Glazing and muntins: Confirm insulated-glass makeup, overall thickness, safety glazing, marine-glazing compatibility, muntin construction, grid pattern, finish, coatings, spacers, and replacement access.

• Sash cleaning and screens: Preserve interior clearance for tilt-in cleaning, balance and lock service, screen removal, and glazing replacement.

• Openings and accessories: Verify field dimensions, rough openings, substrates, anchors, panning, receptors, subsills, mullions, trims, nailing fins, leg extenders, sealants, drainage, and surrounding construction before release.
