Definition: The double-hung window is the most common style of window available. Most likely, you have seen a double hung window and not even known what it was called: it consists of two window sashes (i.e., panes of glass), one on top, one on the bottom.

Please note that double hung window should not be confused with double-glazed window, a method of sandwiching two sheets of glass with an air barrier in the middle.

Many homeowners like double hung windows because they are very good at inhibiting air intrustion into the house, and because this style has a classic appearance. Also, because the style is so popular, window manufacturers and installation companies tend to price double-hungs competitively.

Double hung replacement windows are available, as well as double-hung new construction windows.
