A single hung window usually consists of two panes of glass. The bottom pane moves up and down to allow for ventilation while the other top pane is fixed in place. This type of window is a popular choice and has a number of benefits.
The energy efficiency of single hung windows is often superior to other types as the fixed pane will have a better, longer lasting weather seal that prevents heat transfer from outside. The seal will not degrade as quickly as on a pane that can be opened and closed and this will also save you maintenance costs.
Fixed pane windows will have the highest efficiency but many people like to have the option of letting in some fresh air. For this reason, single hung windows are a great compromise; saving you money on your power bills without turning your whole home into a sealed box.
Windows that open to allow in fresh air and cooling breezes can also have the hidden benefit of erasing the need for air conditioning on milder days which will save you money in the long term. For those days when you really need it though, this type of window is often the best for window mounted air conditioners as they will open wide enough to fit the unit and can be closed around it more easily.
Single hung windows are also more affordable and provide just as much open space as a double-hung window, simply with fewer options. While double-hung windows can be opened from the top or bottom, you cannot open both fully at the same time so the amount of open space is comparable, at a lower price.
As they can only be opened from one side, cleaning can be more difficult than a double hung window but there are newer tilt designs on the market that allow the moving pane to be pushed up and tilted out from the frame, allowing for easier cleaning.
