How They Are Different
The difference is that with single hung only the bottom sash moves, while the top half is permanently fixed. With double hung, both sashes slide up and down. With fewer moving parts single-hung windows conceivably are more weather resistant.
Double Hung
On double hung windows both sashes in the window frame are operable or move up and down. 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. 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.
Single Hung
On single hung windows, the top sash is fixed in place and does not move, but the bottom sash is operable. In modern homes, single-hung windows additionally may be preferred because they cost a bit less than double-hung. Also, it’s often argued that single-hung are less susceptible to air infiltration, or leakage, simply because the upper sash is fixed and cannot develop looseness the same way a moving sash can.</h6 norsk-apotek.com>
