Single-hung windows have a fixed bottom sash while the top is set in place. Double-hung sash windows have two sashes that move vertically. The ability to open both the lower and upper sashes allows for better ventilation. Warm air can escape through the upper sash while cool air can flow into the space below, benefiting from the stack effect.
