Series 3500 Aluminum Double-Hung Windows

Boyd's Series 3500 is our most exceptional commercial aluminum double-hung window, with both the upper and lower sash operating for flexible ventilation and traditional double-hung appearance. Designed to stringent AAMA standards for top-rated performance, the Series 3500 is an excellent choice for demanding coastal applications, hospitals, military buildings, universities, schools, government offices, and other commercial or institutional projects.

Tested to AW-PG85, the Series 3500 features a 4" thermal-break main frame, true divided-lite and simulated muntin options, internal blinds or dual glazing, and side-loaded upper and lower operating sash that can be removed from the interior for maintenance and cleaning. Interior glazing accommodates glass up to 1.25" thick, while screens, coordinated perimeter accessories, finish selections, and project-specific customization support challenging new-construction, replacement, historic-replica, and coastal conditions. Selected impact-rated and blast-resistant configurations are available where the exact unit size, glazing, anchorage, installation method, and current documentation support the project requirements.

When to Use the Series 3500 Double-Hung Window

• Coastal or demanding commercial openings requiring Boyd's highest-performing double-hung aluminum window.

• Hospitals, military buildings, universities, schools, government offices, and other institutional applications.

• Projects requiring AW-PG85 performance, a 4" thermal-break frame, 12 psf water resistance, and glazing up to 1.25" thick.

• Traditional double-hung elevations requiring both upper and lower sash to operate for flexible ventilation and interior maintenance access.

• Openings requiring true divided-lite, interior, or historical muntins, internal blinds, dual glazing, screens, or coordinated perimeter accessories.

• Selected impact-rated or blast-resistant applications where the exact Series 3500 configuration and current supporting documentation match the project requirements.

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

You are viewing the Series 3500 top-performing double-hung window. Review the related Boyd systems below when the project requires single-hung operation, a different double-hung performance class, custodial tilt access, marine glazing, or matching fixed openings.

• Selected impact-rated and blast-resistant configurations are available, with final applicability matched to the exact assembly and current documentation.

Common Series 3500 Coordination Items

• Double-hung operation: Confirm that both upper and lower sash operate, along with lift and lock locations, sash travel, operating force, balance selection, user access, and ventilation requirements.

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

• Coastal exposure: Coordinate design pressures, water resistance, corrosion exposure, drainage, sill conditions, perimeter sealants, flashing, substrates, anchors, and finish requirements.

• Glazing and blinds: Confirm complete glass makeup, overall thickness, safety glazing, interior glazing access, dual glazing, internal blinds, controls, coatings, spacers, and project thermal criteria.

• Muntins and appearance: Coordinate true divided-lite, interior roll-form, or applied historical muntins, grid pattern, profile, finish, reglazing requirements, sash proportions, and reviewing-authority comments.

• Impact requirements: Match the exact Series 3500 configuration, FL33627.1 approval limits, glazing, opening size, positive and negative design pressures, anchors, substrates, installation method, and non-HVHZ limitation to the project requirements.

• Blast requirements: Provide the required protection level, threat criteria, glazing, opening size, anchorage, substrate, receptor, mullion, installation condition, and current documentation requirements.

• Sash removal and screens: Preserve interior access for upper- and lower-sash take-out, cleaning, balance or lock service, screen removal, blind maintenance, 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.
