A double hung window is one of the most popular replacement window styles picked by homeowners. It features two sashes that slide past each other. Because they are not swinging out, they sit flush against the wall. The sashes are also easier to install insect or security screens. These windows are considered safer for high-rise buildings than sliding windows. However, if the window sash has a low sill, special safety measures may be necessary.

A double hung window has two operable sashes, one in front of the other. It also has twin vent stops, so you can lock the bottom sash while allowing it to open. Because these windows are designed with a sliding mechanism, they allow air to flow in and out without restricting the view outside. Additionally, they are easy to clean. In addition, they are available in both full and half screen styles.
