What Are Single-Hung Windows?

In a single-hung window, the bottom one of the two sashes is movable. So, if you want to open up the window, you push the lower half up while the top half remains stationary.

This makes it fairly straightforward and compact, which is one reason for their popularity. They are also less expensive than double-hung windows and typically easier to install and service.

Pros of Single Hung Windows

• Budget Friendly – Because they consist of fewer moving parts, single-hung windows are usually less expensive—both to buy and install.
• Energy Efficiency – With single sash moving, there is less chance for air leakage, which translates to better insulation and lower bills.
• Classic Look – The minimalist, traditional appearance is good with a wide range of home design styles.
• Simplicity – Less mechanical complexity means fewer component breaks.

Cons of Single Hung Windows

• Limited Ventilation – You can’t open the top for passive cooling (hot air escape), which double-hung windows provide.
• Harder to Clean – You can’t clean the outside from inside, and might even require a ladder for cleaning the units on the upper stories.

What Are Double-Hung Windows?

Double-hung windows look the same as single-hung windows, except that their top and bottom sashes both operate. This means you can push the bottom half up and the top half down.

This functionality checkmarks many boxes for optimal windows, such as ease of cleaning, airflow control, and design versatility. They’re now increasingly common in newer constructions.

Pros of Double-Hung Windows

• Better Ventilation – Open both sashes to achieve cross-ventilation or just the top to allow hot air to escape.
• Easier to Clean – Most models enable you to tilt the sashes inwards so you can clean both sides of the glass from inside.
• More Design Options – You get more options for personalization, such as locking systems, tilt or no tilt, multiple sashes, etc.
• Child Safety – You can open just the top sash for ventilation without worrying about kids pushing out the bottom one.

Cons of Double-Hung Windows

• Higher Cost – A steeper price tag upfront—both for the unit, the installation, and subsequent repairs.
• More Moving Parts – All that additional functionality comes with more mechanical parts (such as springs or balances) that will eventually wear out or need repair.
• Potential for Drafts – There is more opportunity for air leakage if the seals break down in any of the sashes or if the window is not well-maintained.

Difference between single hung vs double hung windows

Now, let’s dig into how the differences set them apart in an applied context.

A. Operation and Ventilation

This is arguably the most significant difference. With a single-hung window, as we discussed, only the bottom sash moves to let fresh air in from the outside, but that’s about it. 

Double-hung windows win here, hands down. Why? Because you can open the top sash when it gets hot indoors to let rising warm air escape. Or you can open the bottom to bring in cooler air when the outdoor temperature is pleasant. Or you can open both simultaneously to create a natural cross flow.

B. Cleaning and Maintenance

Double-hung windows also shine here because they typically come with a tilt-in feature. This means you can unlock sashes and tilt them inwards and clean the outside of the glass, particularly convenient for windows in upper-story or hard-to-reach areas. But it’s not a requirement, and lower-end models might not have tilt, so check with the manufacturer. 

Single-hung windows? Not so much. Since the top sash doesn’t move and usually doesn’t tilt, you may have to get up on a ladder or hire help to get the job done. However, that convenience can be offset by its low maintenance need for hardware since it has fewer hinges and locks.

C. Energy Efficiency

Single hung windows will generally be a plus in this regard—but it’s not so much night-and-day. Since they have fewer seams and movable joints, this usually equates to a tighter seal and less opportunity for air leakage.

Double hung windows, with both sashes operable, obviously have more draft potential if the seals fail or are not properly installed. However, double-hung manufacturers have come a long way and now have improved weather stripping and insulation technology, which can counteract that issue—if you purchase a quality product.

The trick here is to seek out windows with high energy performance ratings, including U-factor and Solar Heat Gain Coefficient (SHGC), no matter what type you select.

E. Aesthetic/Architectural Flexibility

Both window types appear quite similar from a design standpoint. Both are also available in many different styles, materials (including vinyl, wood, and aluminum), and finishes.

Single hung windows will have a more classic look and coordinate well with Colonial, Craftsman, or traditional-style homes. The disadvantage is you must make them big enough for proper ventilation. They’re usually a builder’s choice when they want to keep a classic look but at a low cost.

Double-hung windows are more design-friendly, however, and are better suited for contemporary or remodeled homes. They provide visual balance and symmetry and a greater variety of configurations, materials, and grille options.

D. Security Aspects

Single hung windows provide good security primarily due to the fact that the top sash is immovable. That is one fewer potential weak spot, and it’s usually more difficult for an intruder to interfere with a non-moving window.

Double hung windows have more parts to secure, however, most new double-hung windows feature advanced locking systems such as auto-lock and strong latches that make them just as secure when well installed and locked.

But it’s not the same if you have young children or pets. The double-hung style actually provides a safety benefit—you can open only the top sash for ventilation while keeping the bottom sash closed and locked, reducing the chance of them escaping out the bottom.

Summarising the differences between single-hung and double hung windows:

What is the Cost of Single Hung vs. Double Hung Windows?

Expect to pay $100 to $500 per single hung unit, depending on size, material, and brand. With installation it will set you back at around $150 to $650 per window. Double hung models, however, usually begin at $200 to $1000, and including installation, the overall cost can rise to $350 to $1400 or more for each window.

But you’re paying for the added convenience, versatility, and often better resale value—especially over the long haul. In some cases, the extra up-front investment in double hung windows pays off in easier cleaning and better airflow, which can be worth every penny.

How to Choose Single Hung or Double Hung Windows for Your Project?

Single-hung or double-hung, it’s really up to what you need, want, and can pay for. Ask yourself these questions to find the best fit:

• What’s your budget? If finances are the top priority, single-hung windows will be the more desirable choice.
• How important is ventilation to you? In case you love the air movement and the ability of cross-ventilation, double-hung windows are the hands-down winner.
• How much do you value easy cleaning? Double hung windows are preferred by family homes for the ease of cleaning, but businesses with frequent cleaning services can maintain single hung windows.
• What room do you need it in? Bedrooms and bathrooms can use the extra ventilation of a double hung window more, while garages or guest rooms can get by with a single hung.

Neither is definitely “better.” Single-hung windows are less costly, while double-hung windows are more ventilated and maintainable.

Q: Do single hung windows tilt in for cleaning?

Typically, no. The upper sash in single hung windows is fixed, while the lower only moves up and down on tracks.

Q: What is the main drawback to the use of a double-hung window?

Double-hung windows are more expensive than single-hung versions. And, more moving parts may ultimately lead to more maintenance.

Q: Are double-hung windows out of style?

Not at all! Double hung windows are still timeless and remain highly popular in both modern and traditional home styles.
