Double-hung Window
Definition and meaning of Double-hung Window in real estate.
A double-hung window is a type of window featuring two vertical sashes that slide up and down independently within the frame. This design allows for flexible ventilation, as users can open the top sash, the bottom sash, or both at the same time.
In more detail
Unlike single-hung windows where only the bottom sash moves, double-hung models offer superior air circulation by letting warm air escape through the top opening while cool air enters through the bottom. Modern versions typically include sashes that tilt inward, making it easy to clean both the interior and exterior glass from inside the home.
They are popular in traditional American architectural styles, such as Colonial and Craftsman homes. When buying a home, check that the sash balances or cords function smoothly and that the locks align properly.
