Double Hung Windows

A double-hung window is a type of window with two panels (sashes) that slide up and down. Both the top and bottom sections can open, which lets you control airflow better than windows where only one part moves.

You can open the bottom to let fresh air in and the top to let warm air out. Many double-hung windows also tilt inward, making them easier to clean from inside your home. They’re popular because they’re simple to use, safe, and work well with many home styles.
