A popular storm window replacement in updated homes, double-hung windows are specially engineered to improve utility bills and home comfort. The panes are also easy to get to, and some are designed with tilting, locking sashes to make window cleaning less of a chore for residents. In double-hung styles, the window opens by sliding the upper or lower sash vertically past its opposite--optimizing air circulation throughout the home. Raising the lower sash brings in cool air, while lowering the top pane vents hot air to the outdoors.

Double-hung windows are composed of the following parts:

• Frame--combination of jambs, sill and head surrounding the opening.
• Sill--horizontal portion of the window forming a base at the bottom.
• Jamb--vertical parts along the side of an opening.
• Head--horizontal portion along the opening's top.
• Sash--assembly of stiles and rails that hold the glass in place. The upper and lower sashes both move in double-hung styles.
• Grid or grille--dividing bars that break up the glass pane; often used for design purposes.

While most double-hung designs have equal-sized sashes, cottage styles have a smaller upper sash, allowing less ventilation at the bottom of an opening, and more at the top.
