double-hung windows
Two movable panes
Double-hung windows have two sashes that slide vertically in separate tracks, allowing either the top or bottom half to open.
This distinguishes them from single-hung windows, where only the bottom sash moves.
The design improves ventilation—opening both sashes creates airflow as warm air exits above while cool air enters below.
The old house still had its original double-hung windows.
