Series 3250XTC-G Casement Project-In Historic-Replica Windows

The Boyd Series 3250XTC-G (PI) is a historic-replica commercial aluminum casement window that opens inward and combines unparalleled energy efficiency with a sleek historic appearance. Its industry-leading 39mm structural polyamide thermal strut, 3.25" main frame depth, and tank sill support projects driven by the need to save energy, reduce condensation, improve water performance, and deliver proven performance over the life of the building.

Designed to pass meticulous historic review, the Series 3250XTC-G (PI) features exterior snap-in muntins, a flush appearance, .125" structural wall areas, and a mitered, corner-keyed, and crimped sash for increased strength. The interior-glazed system is AAMA tested to AW-PG100, accommodates 1" and 1.75" glazing with a .5" glass bite, 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-G Project-In Casement

  • Historic restoration, adaptive-reuse, renovation, or replacement openings requiring a side-hinged casement window that opens inward.

  • Energy-conscious projects driven by the need to save energy, reduce condensation, and meet stringent thermal-performance requirements.

  • Project-in openings where a tank sill, interior glazing access, and coordinated interior operating clearance are important.

  • Historic-review projects where exterior snap-in muntins, divided-lite patterns, visible profiles, glazing, and finish must be coordinated.

  • 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.

Series 3250XTC-G Project-In Advantages

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

  • Designed to pass meticulous historic review while delivering a flush, sleek historic-replica appearance.

  • Exterior snap-in muntins support historic divided-lite patterns and architectural detailing.

  • Tank sill supports increased water performance for the inward-opening configuration.

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

  • Two rows of weather stripping support ideal air 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.

Common Series 3250XTC-G Project-In Coordination Items

  • Historic review: Coordinate existing profiles, visible sightlines, sash proportions, muntin pattern, finish, glazing character, and required documentation with the architect and reviewing authority.

  • Project-in operation: Confirm interior clearance, hardware, opening angle, screens, shades, furnishings, wall conditions, and other interior obstructions.

  • Tank sill and water management: Coordinate sill conditions, drainage, perimeter sealants, receptors, subsills, surrounding construction, and installation details.

  • Muntins and glazing: Confirm exterior snap-in muntin profiles, grid pattern, lite divisions, glass makeup, overall thickness, glass bite, 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.

  • 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.
