Series 3250XTP Aluminum Project-Out Thermal-Strut Windows

Boyd's Series 3250XTP Project-Out is a high-performance commercial aluminum thermal-strut window with outward-projecting operation. Its industry-leading 39mm polyamide thermal strut and 3.25" main frame depth support low U-value performance for schools, universities, government offices, hospitals, military buildings, and other commercial applications that must meet stringent energy-code requirements and maximize performance over the life of the building.

Engineered to AW-PG80 projected-window requirements, the Series 3250XTP Project-Out is interior glazed with 1" or 1.75" glass, snap-in glazing beads, and a .5" glass bite. Its mitered, corner-keyed, and crimped sash provides increased strength, while .125" structural wall areas, square-cut mechanically fastened main-frame construction, two rows of weatherstripping, and pressure equalization support durability, ideal air performance, and superior water performance. The flush closed-vent appearance gives designers the clean, sleek look that is in high demand, while screens, muntins, internal blinds or dual glazing, coordinated perimeter accessories, and configuration-specific blast-resistant capabilities support demanding commercial projects.

When to Use the Series 3250XTP Project-Out Window

• Commercial openings requiring outward-projecting operation rather than an inward-projecting vent or side-hinged casement.

• Schools, universities, government offices, hospitals, military buildings, and other projects with stringent energy-code requirements.

• Energy-conscious new-construction or replacement projects seeking a 39mm thermal-strut window designed to reduce frame heat transfer and support low U-value performance.

• Projects requiring AW-PG80 projected-window performance, a 3.25" pressure-equalized frame, 15 psf published water resistance, and glazing up to 1.75" thick.

• Openings requiring a flush closed-vent appearance, interior glazing, true or simulated muntins, internal blinds or dual glazing, screens, and coordinated perimeter accessories.

• Blast-resistant applications where the exact Series 3250XTP Project-Out configuration, glazing, anchorage, opening size, and current supporting documentation match the project requirements.

Choosing a 3250XT Project-Out Configuration

You are viewing the standard 3250XTP Project-Out projected window. It opens outward but is not the same as the side-hinged 3250XTC casement. Review the related 3250XT configurations below when the project requires historic-replica exterior snap-in muntins, inward projection, side-hinged casement operation, or a matching fixed unit.

Series 3250XTP Project-Out Window Advantages

• Industry-leading 39mm extra-wide polyamide crimped-in-place structural thermal barrier for extremely low listed U-values.

• Published 0.43 U-factor using 0.24 center-of-glass U-factor under NFRC 100.

• A 3.25" main frame depth with .125" structural wall areas for durability.

• Pressure equalization supports superior water performance in the project-out configuration.

• The vent presents a flush appearance with the exterior and interior main-frame faces when closed for a desirable, clean look.

• Interior snap-in glazing accommodates 1" and 1.75" glass configurations with a .5" glass bite.

• Mitered, corner keyed, and crimped sash construction provides increased strength; main-frame construction is square-cut and mechanically fastened.

• Four-bar stainless steel friction hinges are paired with project-specific operating hardware selected for the projection direction and approved documentation.

• Two rows of weatherstripping support ideal air performance.

• True divided-lite, interior roll-form, surface-applied, and historical muntin options, internal blinds or dual glazing, and screens are available.

• Panning, thermally broken receptors, subsills, caulk backers, mullions, snap trims, finishes, and project-specific customization support complex opening conditions.

• Performance Level 10 forced-entry requirements and configuration-specific blast-resistant capabilities support demanding commercial applications.

Common Series 3250XTP Project-Out Coordination Items

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

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

• Pressure equalization and drainage: Coordinate sill details, drainage paths, perimeter sealants, flashing, receptors, subsills, panning, adjacent construction, and installation details so the intended water-management approach is maintained.

• Glazing and thermal performance: Confirm complete glass makeup, overall thickness, center-of-glass performance, spacer, safety glazing, coatings, interior glazing access, .5" glass bite, and project-specific U-factor or condensation criteria.

• Muntins and appearance: Coordinate true divided-lite, interior roll-form, surface-applied, or historical muntin construction, grid pattern, profile, finish, and reglazing requirements. Use the -G configuration when exterior snap-in muntins are required.

• Hardware and screens: Confirm the project-specific operating hardware permitted for project-out use, along with four-bar hinges, screen type, wickets, hardware clearances, user operation, and cleaning access.

• Performance documentation: The live product page and product sheet list AW-PG80, 120 psf structural performance, and 15 psf water resistance. The shared guide specification contains editable performance selections and an internal AW-PG100 reference, so confirm the current certified test report and approved project documentation.

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

• Openings and accessories: Verify field dimensions, rough openings, substrates, anchors, panning, thermally broken receptors, subsills, mullions, caulk backers, snap trims, sealants, drainage, finishes, and surrounding construction before release.

What to Send Boyd for a Series 3250XTP Review
