Replacement window

High-Performance Casement Window

A deeper-frame casement direction for projects where tested air, water, structural and thermal performance require closer review. The sash opens outward for ventilation and closes against a compression seal, while available insulated-glass packages can include double- and triple-pane construction. This option is distinct from the slimmer residential casement because frame depth and documented ratings may affect installation planning and product selection.

Key features

  • Deeper frame construction
  • Outward crank operation
  • Compression-seal closing action
  • Documented performance packages
  • Double- and triple-pane choices

Selection guidance

Where this configuration fits.

This deeper casement direction is intended for openings where frame depth and documented air, water, structural or thermal performance deserve closer attention. It retains crank operation and a compression close while allowing a more performance-led specification.

Best for

  • Exposed elevations
  • Projects requiring documented performance comparison

Configuration options

  • Opening direction
  • Glass and spacer package
  • Frame, jamb and finish configuration

Considerations

  • Deeper frames affect jamb and trim planning
  • Published ratings apply only to the quoted size and configuration
  • Exterior sash clearance is required
