Generated explanation

Three diagrams show a closed sash window and the opening arrangements of double-hung and single-hung windows. Each window has two overlapping, vertically arranged glazed sashes with muntins dividing the glazing. The double-hung example has its upper sash lowered and lower sash raised, creating openings at both the top and bottom; arrows indicate warm air leaving above and cool air entering below. The single-hung example retains the upper sash in place while the lower sash is raised, with arrows showing air exchange through the bottom opening. Dashed outlines indicate the window opening and the inside and outside orientation.
