Series 3250XTC Casement Project-Out Windows

The Boyd Series 3250XTC (PO) is a commercial aluminum thermal-strut casement window that opens outward and delivers a sleek appearance with the performance needed for stringent energy-code requirements. Its industry-leading 39mm structural polyamide thermal strut, 3.25" main frame depth, and interior-glazed design make it a high-performing, design-conscious choice for schools, universities, government offices, military buildings, hospitals, and other energy-conscious commercial applications.

Designed for outstanding performance over the life of the building, the Series 3250XTC (PO) features .125" structural wall areas and a mitered, corner-keyed, and crimped sash for increased strength. The vent sits flush with the exterior and interior faces of the main frame when closed for a clean modern appearance. The system is AAMA tested to AW-PG100, accommodates 1" and 1.75" glazing, and is available with screens, blinds or dual glazing, coordinated accessories, and blast-resistant configurations where supported by current project-specific documentation.

When to Use the Series 3250XTC Project-Out Casement

• Commercial openings requiring a side-hinged casement window that opens outward.

• Energy-conscious projects requiring a 39mm thermal strut, interior glazing, and a high-performing 3.25" aluminum window system.

• Schools, universities, government offices, military buildings, hospitals, and other commercial applications seeking outstanding performance over the life of the building.

• Contemporary elevations where the flush closed-vent appearance and clean frame profile are important design considerations.

• Operable openings requiring AW-PG100 casement performance, glazing up to 1.75", screens, and project-specific hardware coordination.

• Blast-resistant applications where the exact opening size, glazing, anchorage, installation method, and supporting documentation are reviewed for the selected configuration.

Choosing a Related Series 3250XT Window

You are viewing the standard Series 3250XTC Project-Out casement configuration. Review the related 3250XT options below when the project requires inward casement operation, projected rather than casement operation, a fixed opening, or the historic-replica “-G” version of this project-out casement.

Series 3250XTC Project-Out Advantages

• Industry-leading 39mm extra-wide polyamide structural thermal strut supports impressively low U-values and stringent energy-code goals.

• Flush closed-vent appearance creates a desirable, clean modern look at both the exterior and interior faces of the main frame.

• .125" structural wall areas and mitered, corner-keyed, and crimped sash construction provide increased strength.

• Two rows of weather stripping support ideal air performance, while pressure equalization supports superior water performance.

• Interior glazing, snap-in glazing beads, .5" glass bite, and 1" or 1.75" glazing provide specification flexibility.

• Available with screens, blinds or dual glazing, panning, receptors, caulk backers, mullions, and snap trims.

• Complies with Performance Level 10 forced-entry requirements.

• Blast-resistant configurations are available, with final performance documentation matched to the selected assembly and project criteria.

Common Series 3250XTC Project-Out Coordination Items

• Project-out operation: Confirm exterior clearance, hardware, opening angle, screens, adjacent walls, landscaping, walkways, and other exterior obstructions.

• Glazing: Confirm glass makeup, overall thickness, .5" glass bite, safety-glazing requirements, interior-glazing access, blinds, and dual-glazing requirements.

• Thermal performance: Provide the project U-factor, condensation, energy-code, center-of-glass, and whole-window requirements so the selected configuration and glazing can be reviewed together.

• Fixed and operable coordination: Coordinate sightlines, frame depth, glazing, finish, mullions, and visual alignment with adjacent Series 3250XTF fixed or 3250XTP projected windows.

• Blast requirements: Match the exact window size, glazing, anchorage, substrate, receptor, mullion, installation method, and protection criteria to current configuration-specific documentation.

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