Single-Hung vs. Double-Hung Windows: Which Is Right for Your Home?

A single-hung window has a fixed top sash and a bottom sash that slides up. A double-hung window lets both sashes move, and both usually tilt in so you can clean the outside of the glass from inside the house. They look almost identical from the street. Single-hung costs less and has fewer moving parts. Double-hung costs more but gives you more control over airflow and much easier cleaning, which is why it is the usual pick for second-floor rooms.

How Single-Hung and Double-Hung Windows Work

Both styles have two sashes stacked in one frame. On a single-hung window, only the bottom sash opens; the top one is fixed in place. On a double-hung window, the top sash can slide down and the bottom sash can slide up, independently. Most double-hung windows also let each sash tilt inward on its hinge points, so the exterior side of the glass faces you for cleaning.

Which One Fits Each Room?

• Second-floor rooms: double-hung, so every pane can be cleaned from inside without a ladder.
• Kids' rooms: double-hung lets you ventilate through the top sash and keep the bottom closed, which keeps the open part of the window out of reach. Window opening control devices add another layer of protection.
• Ground-floor windows behind landscaping or a fence: single-hung is often fine, and the savings add up across a whole house.
• Rooms that trap heat: double-hung, so you can vent the warm air near the ceiling on mild days.

Can I mix single-hung and double-hung in the same house?

Yes. Because they look nearly the same from outside, many homeowners choose double-hung upstairs and single-hung on the ground floor to balance convenience and cost. The written quote should list the style for each opening so you know exactly what you are getting. Our guide on how to choose a window replacement company covers what else a quote should spell out.

The Bottom Line

Choose double-hung where cleaning and airflow matter most, and single-hung where they do not and the savings help.
