Series 2300 NSL Narrow-Sightline Aluminum Project-Out Windows

Boyd's Series 2300 NSL is a versatile commercial aluminum narrow-sightline project-out window with thermally broken construction and a compact 2.375" main frame depth. Its slim visual profile, outward-projecting operation, and safe, sleek appearance make the Series 2300 NSL an excellent choice for schools, universities, government offices, hospitals, military buildings, and other commercial or institutional applications.

Tested to AW-PG80, the Series 2300 NSL Project-Out combines 15 psf water resistance, 120 psf structural performance, glazing up to 1.5" thick, stainless-steel four-bar friction hinges, and four operating-hardware packages. True divided-lite, interior, and historical muntins, blinds or dual glazing, removable screens, coordinated perimeter accessories, finish selections, and custom options support contemporary architecture, restoration, renovation, window replacement, and new construction. The standard Series 2300 Project-Out is available when narrow sightlines are not required.

When to Use the Series 2300 NSL Project-Out Window

• Contemporary commercial openings where narrow aluminum sightlines and outward-projecting operation are important architectural requirements.

• Schools, universities, government offices, hospitals, military buildings, and other commercial or institutional applications.

• Renovation, replacement, or new-construction projects requiring a compact 2.375" frame and a slimmer visible profile.

• Projects requiring AW-PG80 performance, 15 psf water resistance, 120 psf structural performance, and glazing up to 1.5" thick.

• Openings where outward operation is preferred because interior furnishings, blinds, casework, circulation, or occupant use make inward projection less practical.

• Projects requiring true, interior, or historical muntins, blinds or dual glazing, removable screens, multiple operating-hardware packages, perimeter accessories, finish options, and customization.

Choosing a Standard or Narrow-Sightline Project-Out Window

You are viewing the narrow-sightline Series 2300 NSL Project-Out projected window. It opens outward but is not a side-hinged casement. Unlike the standard Series 2300 Project-Out, the current narrow-sightline product data lists no impact or blast capability. Review the related Boyd systems below when the project requires standard sightlines, inward projection, a different performance class, 39mm thermal-strut construction, or an associated narrow-sightline fixed window.

Series 2300 NSL Project-Out Window Advantages

• Narrow sightlines create a safe, sleek contemporary appearance for projected-out commercial openings.

• Versatile thermally broken construction for schools, universities, government offices, hospitals, military buildings, renovation, replacement, and new construction.

• AW-PG80 performance with 15 psf water resistance and 120 psf structural performance.

• A compact 2.375" frame accommodates glazing up to 1.5" thick.

• Stainless-steel four-bar friction hinges can be coordinated with lever-and-cam, custodial, telescoping push-bar, or gear-type rotary operating hardware.

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

• True divided-lite, interior roll-form, and applied historical or simulated muntins support contemporary, traditional, and restoration designs.

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

• Blinds or dual glazing and tight-fitting removable screens expand project flexibility.

• Panning, receptors, subsills, mullions, trims, nailing fins, finishes, and custom options support varied opening and installation conditions.

• Published CRF 55 and U-value 0.51 provide current thermal-performance references for the standard product configuration.

• Also available as the standard Series 2300 Project-Out when narrow sightlines are not required.

Common Series 2300 NSL Project-Out Coordination Items

• Projected-out operation: Confirm that the documents require an outward-opening projected window rather than a side-hinged project-out casement. Coordinate hinge location, opening angle, operating-hardware package, hardware reach, opening force, user access, and ventilation strategy.

• Exterior clearance: Review the outward projection path against walkways, railings, sunshades, screens, louvers, adjacent walls, security conditions, maintenance access, and other exterior obstructions.

• Standard or narrow sightlines: Confirm whether the project requires the Series 2300 NSL or standard Series 2300 before finalizing elevations, exposed frame dimensions, details, mullions, associated fixed windows, and performance requirements.

• Performance distinction: Both the standard and NSL Project-Out configurations are published as AW-PG80, but the standard Series 2300 product data lists impact and blast availability while the Series 2300 NSL data lists both as unavailable. Do not transfer those capabilities between configurations.

• Glazing and thermal performance: Confirm complete glass makeup, overall thickness, safety glazing, glazing access, blinds or dual glazing, coatings, spacers, and required CRF or U-value.

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

• Hardware and screens: Select the lever-and-cam, custodial, telescoping push-bar, or rotary hardware package and coordinate friction hinges, screens, wickets, accessibility, security, cleaning, and maintenance requirements.

• Fixed-window coordination: Coordinate frame depth, exposed sightlines, glazing, muntins, finish, mullions, receptors, panning, and elevation alignment with the associated Series 2200 NSL fixed window.

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

What to Send Boyd for a Series 2300 NSL Review

Send as much of the following project information as available:

• Project name, location, building type, bid date, construction schedule, architectural drawings, elevations, window schedules, specifications, and opening sizes.

• Glass makeup, overall thickness, coatings, spacers, safety glazing, blinds or dual glazing, muntin construction, grid pattern, and required CRF or U-value.

• Associated Series 2200 NSL fixed-window requirements, including sightline, frame, glazing, muntin, finish, mullion, and elevation-alignment expectations.

• Required AW-PG80, air, water, structural, thermal, forced-entry, security, energy-code, and jurisdictional criteria.

• Panning, receptor, subsill, mullion, trim, nailing-fin, anchor, sealant, drainage, substrate, installation, finish, and submittal requirements.
