One moving panel
Ventilation is limited to the operating portion while the companion section stays fixed.
Styles, features and documented details
The operating-sash view identifies the movable horizontal section and its fixed companion, with profile evidence for track, screen and replacement depth comparisons.
One sash travels horizontally beside a fixed section, providing simple ventilation with no exterior swing. It works well where the opening is wider than tall and where access to the track for routine cleaning is practical.
