Single Hung Window
Single hung windows are suitable for areas with limited space such as bathrooms, hallways, and closets. The benefit of single hung windows is that they do not take any extra space when you open them like other types of windows.
In a single hung window the upper sash is fixed and the lower sash operates vertically. You will be able to slide the panel in order to allow for ventilation. The sliding pane of our single hung windows also tilts inward to provide easy access to both sides for cleaning.
This is also a cheap opening window style.
