Series 3250XTP-G Historic-Replica Aluminum Project-Out Windows

Boyd's Series 3250XTP-G Project-Out is a high-performance historic-replica 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 window performance, while exterior snap-in muntins provide a classic historic appearance with modern commercial-window performance. The high-performing, sleek Series 3250XTP-G is designed to pass meticulous historic review for restoration, adaptive-reuse, and energy-conscious replacement projects.

Engineered to AW-PG80 projected-window requirements, the Series 3250XTP-G 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. Screens, true and simulated muntins, internal blinds or dual glazing, coordinated perimeter accessories, and configuration-specific blast-resistant capabilities support demanding historic-replica projects.

When to Use the Series 3250XTP-G Project-Out Window

• Historic-replica, restoration, adaptive-reuse, or replacement openings requiring outward-projecting operation and exterior snap-in muntins.

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

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

• Historic-review projects requiring a flush, sleek appearance, classic exterior muntin detailing, coordinated sash proportions, finish matching, and project-specific opening details.

• Openings requiring interior glazing, a .5" glass bite, true or simulated muntins, internal blinds or dual glazing, screens, and coordinated perimeter accessories.

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

Choosing a 3250XT Historic-Replica Project-Out Configuration

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

Series 3250XTP-G Project-Out Window Advantages

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

• Historic-replica appearance designed to pass meticulous historic review.

• Exterior snap-in muntins provide a classic historic look with modern commercial-window performance.

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

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

• Flush vent appearance when closed provides a sleek, design-conscious historic replica.

• 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 friction-hinge packages can be coordinated with lever-and-cam latches, custodial cam latches, telescoping push bars, or gear-type rotary operators.

• Two rows of weatherstripping support ideal air performance.

• True divided-lite, interior, surface-applied, and historical muntins, 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-G 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, operator 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.

• Historic review: Coordinate existing profiles, sightlines, sash proportions, exterior snap-in muntins, grid pattern, muntin width and depth, finish, panning, perimeter conditions, and reviewing-authority comments.

• 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.

• Hardware and screens: Select the required lever-and-cam latch, custodial latch, push-bar, or rotary-operator package and coordinate screen type, wickets, hardware clearances, user operation, and cleaning access.

• 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-G Review

Send as much of the following project information as available:
