System Double-Hung

One of the most popular type of window in the United States
The Double-Hung window can be lifted from the bottom or lowered from the top with two independent sashes. They are easy to clean as both of the sashes tilt inward for simple access to the exterior and interior panes of glazing. Double-Hung windows do not require any extra space to operate, so they can maximize both interior and exterior space.
