A window with vertical-moving panels is which type of window?

• A. Single Hung
• B. Casement
• C. Sliding Casement
• D. Double Hung

Answer: (D)

Vertical-moving sashes indicate panels that slide up and down. When both the upper and lower sashes are operable and move vertically, the window is double-hung. A single-hung would have only one sash (usually the bottom) that moves while the top remains fixed. Casement windows open by hinged sides and swing, not slide, and a sliding casement moves horizontally. So the description of two vertical-moving panels best matches a double-hung window.
