What is a characteristic of double hung windows?

Double hung windows are distinguished by their design, which features two operable sashes. This means that both the upper and lower portions of the window can move vertically, allowing for versatile ventilation options. Homeowners can open either the top or bottom sash independently, providing flexibility in managing airflow while still maintaining security and aesthetics.

The presence of two operable sashes is a key characteristic that sets double hung windows apart from other window types, such as single hung windows, which only have one moving sash. This design allows for improved control over temperature and air circulation within a room, making double hung windows a popular choice in many residential settings.
