Series 4300 Commercial Aluminum Project-In Windows

Boyd's Series 4300 is a high-performance commercial aluminum project-in window that offers a contemporary, seamlessly functioning solution for modern architectural design. Attractive sightlines and inward-projecting operation make the Series 4300 an excellent choice for colleges, schools, offices, government buildings, hospitals, military structures, and other demanding commercial or institutional applications.

Tested to AW-PG100, the thermally broken Series 4300 features a 4" main frame, dual corner-key construction, inside- or outside-set glazing up to 1.5" thick, three hardware-package paths, and two rows of weatherstripping at the sash. True, interior, and historical muntins, blinds or dual glazing, screens, coordinated perimeter accessories, finish selections, and custom options support contemporary, coastal-weather, historic-replication, renovation, and new-construction requirements. The Series 4300 can be appropriate for buildings in hurricane regions where its documented non-impact AW-PG100 performance meets the project criteria; it is not an impact-rated window.

When to Use the Series 4300 Project-In Window

• Contemporary commercial architecture requiring an inward-opening projected window with attractive sightlines and a clean operable-window appearance.

• Colleges, schools, offices, government buildings, hospitals, military structures, and other commercial or institutional applications.

• Projects requiring AW-PG100 performance, a 4" thermal-break frame, 15 psf water resistance, 150 psf structural performance, and glazing up to 1.5" thick.

• Coastal-weather or hurricane-region buildings where the documented non-impact Series 4300 performance, glazing, size, anchorage, and installation conditions meet the project requirements.

• Historic-replication or divided-lite applications requiring true, interior, or historical muntins, coordinated profiles, finish review, and project-specific opening details.

• Openings requiring inside- or outside-set glazing, blinds or dual glazing, removable screens, multiple hardware packages, perimeter accessories, and custom options.

Choosing a Boyd Project-In Window

You are viewing the Series 4300 inward-opening projected window. It is not a side-hinged casement and is not impact rated. Review the related Boyd configurations below when the project requires outward projection, a shallower frame, narrow sightlines, 39mm thermal-strut construction, side-hinged casement operation, or a matching fixed unit.

Series 4300 Project-In Window Advantages

• Contemporary, seamlessly functioning project-in design with attractive sightlines for modern architectural applications.

• AW-PG100 performance with 15 psf water resistance and 150 psf structural performance.

• A 4" thermally broken main frame and inside- or outside-set glazing accommodate glass up to 1.5" thick.

• Dual corner-key construction supports demanding commercial and institutional applications.

• Three hardware-package paths provide standard, custodial, or pole-operated project-in control.

• Stainless steel four-bar friction hinges support controlled projected-in operation.

• 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 historic-replication designs.

• Blinds or dual glazing, removable screens, panning, nailing fins, leg extenders, receptors, subsills, mullions, trims, finishes, and customization options support varied project conditions.

• Published 0.59 U-value provides a current thermal-performance reference for the standard product configuration; confirm the selected glazing and project documentation before release.

Common Series 4300 Project-In Coordination Items

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

• Interior clearance: Review the inward projection path against interior trim, blinds, shades, screens, furniture, casework, occupants, security devices, circulation paths, and maintenance access.

• Coastal and hurricane-region requirements: Coordinate design pressures, water resistance, corrosion exposure, finish, adjacent metals, drainage, flashing, sealants, anchors, substrates, and installation conditions. Series 4300 Project-In is not impact rated.

• Glazing-set direction: Confirm inside- or outside-set glazing, complete glass makeup, overall thickness, safety glazing, glazing access, blinds, dual glazing, coatings, spacers, and required U-value.

• Muntins and historic appearance: Coordinate true, interior, or historical muntins, grid pattern, lite divisions, profile, attachment method, finish, reglazing requirements, existing-window conditions, and reviewing-authority comments.

• Hardware and screens: Select the combination lever-and-cam, custodial cam-latch, or pole-operated hardware package and coordinate friction hinges, screens, accessibility, security, cleaning, and maintenance requirements.

• Member thickness: The live product page and current guide specification list different sash-wall values. Confirm the governing approved drawings, specification, and current product documentation before submittal or release.

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

What to Send Boyd for a Series 4300 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.

• Confirmation that the opening requires project-in projected operation, along with opening angle, hardware package, vent size, inward clearance, screens, user access, and maintenance requirements.

• Required coastal-weather or hurricane-region criteria, design pressures, water resistance, corrosion exposure, finish, glazing, anchors, substrates, and installation conditions.

• Glazing-set direction, glass makeup, overall thickness, coatings, spacers, safety glazing, blinds or dual glazing, muntin construction, grid pattern, and required U-value.

• Historic-replication requirements, existing-window photographs or profiles, sightlines, sash proportions, muntin details, finish, and reviewing-authority comments.

• Required AW-PG100, air, water, structural, thermal, forced-entry, security, energy-code, and jurisdictional criteria.

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