Double-Hung Windows: Pros and Cons


The double-hung window is the most common style of window available today. And the reason is simple: double-hung windows are easier to clean.


Double-hung windows with tilt-in (also called tilt-out) design can be cleaned from inside the house. With single hung windows (and older double-hung windows without tilt-out function), it's difficult or impossible to clean the outside of the lower sash from indoors. You have to reach it from the outside--easy if the window is ground-level, difficult if the window is upper-level.


Single-hung windows can also have a tilt-in or removable lower sash, but you still have to reach outside the window to clean the upper sash, a perilous task.


The ability to open the upper sash on a double-hung window is another advantage in terms of airflow. Sometimes it's nice to open the upper sash and not have air blowing in from below. You can also create a minor recirculating effect by opening both sashes about halfway or less. In theory, this allows warmer air to escape through the upper sash and cooler air to enter through the lower sash. But in reality, this natural convection has little cooling effect on a room.


Finally, for homes with small children, double-hung windows' top opening sash allows you to keep the lower sash closed, yet still have airflow coming through the open top.
