Single-hung vs double-hung windows: Which belong in your home?

• The main difference between single-hung and double-hung windows is the number of movable sashes.
• Single-hung windows are generally less expensive but offer more limited ventilation.
• Double-hung windows provide better airflow and are easier to clean but typically cost more.

Whether building your dream home or upgrading your current one, don’t skip on investing in the right windows for your home. Ventilation, natural light and design aesthetic are all important home features that are affected by the type of window you choose.

When it comes to types of windows, two of the most common styles are single-hung and double-hung. They look similar from the exterior, but each style offers pros and cons that we researched and highlighted below. 

To learn the actual difference between the two, the USA TODAY team consulted Nicole Willits, Design Trend, Product and Sustainability Manager at Pella. 

Here’s everything to know about single-hung versus double-hung windows, including window prices, installation, benefits and drawbacks to consider. 

Single-hung vs. double-hung windows: At a glance 

The main difference between double-hung and single-hung windows comes down to the sash, the frame-like part of the window that keeps the glass panels in place. 

The bottom sash in single-hung windows is the only part that moves, and for double-hung windows, both the top and bottom sash move. When double-hung windows are open, air can flow from the top and bottom of the frame, but single-hung windows only have one opening for air to move. 

Single-hung windows: Cost, measurements and use 

Advantages of single-hung windows 

With just one movable sash, single-hung windows can be more affordable and require less maintenance. The simpler design is what makes this type of window cost less to install.

This window design works on many houses and is particularly good for tight spaces where you don’t want window panes protruding outward or inward, or on ground-floor rooms for better security. 

In terms of energy efficiency, “single-hung windows can have slightly tighter seals, which can translate in marginally better energy performance, though the materiality and glazing technology often means the difference in performance between the two types is minimal,‌” Willits explains. 

Window manufacturers can offer upgraded energy efficiency and sealing options if that’s important to homeowners. 

Disadvantages of single-hung windows 

One of the biggest drawbacks to single-hung windows is the limited ventilation. Because the top sash stays put, only one section allows air to flow in and out. 

Single-hung windows can also be harder to clean, especially on top floors, where a ladder is needed to reach the upper pane. In the same realm of safety risks, single-hung windows only open from the bottom, which could pose a risk to young children or pets. 

Single-hung windows cost 

The cost of single-hung windows varies widely depending on the materials, size, design, additional features and installation prices. 

Frame materials like vinyl and aluminum are cheaper options, and wood and fiberglass will make the price go up. And of course, the bigger the window and more materials required, the higher the price. 

While some big box home retailers sell single-hung windows for less than $150, that doesn’t include installation. Homeowners should expect to pay anywhere from $300 to over $1,000 per window, depending on the factors above. 

Single-hung windows standard measurements 

We researched standard window sizes, and put together this comprehensive guide. For single-hung windows, here are the standard sizes:

Standard widths: 24, 28, 32, 40, 44 or 48 inches 

Standard heights: 36, 44, 48, 52, 54, 60, 62 or 72 inches 

Which rooms are best for single-hung windows? 

Single-hung windows can be placed in any room throughout a house, but some rooms might be better than others. 

Since limited ventilation can be a drawback for single-hung windows, secondary rooms like the bathroom, guest room, basement or garage can be better rooms than primary areas like bedrooms, living rooms and kitchens where ventilation might be more important. 

Single-hung windows are also easier to reach and clean if they are on the first floor. 

Double-hung windows: Cost, measurements and use 

Advantages of double-hung windows 

Double-hung windows have two operating sashes, which means better ventilation. “Homeowners can open the bottom sash to let cool air in while lowering the top sash to release the warm air that naturally rises, creating a natural convection cycle,” Willits says.

Design-wise, Willits explains that double-hung windows are versatile and can fit the style of many homes, ranging from Colonial to Farmhouse:

“Historically, these preferences evolved during a period when the double-hung sash allowed the homes to regulate the airflow before the advent of air conditioning,” she said. “However, double-hung windows remain a defining feature of traditional facades and many of the divided light grille patterns are highlights of a home’s style.”

Disadvantages of double-hung windows 

Double-hung windows are more expensive than single-hung because of the extra mechanical parts with two sashes. Maintenance can also be more expensive, especially if the latches, springs or weatherstripping need fixing. 

Another concern is leakage, as two dual slashes create more opportunity for air to seep through. However, as Willits noted above, the differences in energy efficiency between double-hung and single-hung windows can be minimal. 

Double-hung windows cost 

Double-hung windows are more expensive than single-hung windows, with prices for one window ranging from around $300 (without installation), going up to $2,000 or more depending on style, materials and installation fees. 

Double-hung windows are often bigger with more options for sizes than single-hung, which increases the price. 

Double-hung windows standard measurements 

Double-hung and single-hung windows typically have the same standard sizing, which is:

Standard widths: 24, 28, 32, 40, 44 or 48 inches 

Standard heights: 36, 44, 48, 52, 54, 60, 62 or 72 inches 

Large window companies like Renewal by Andersen, Pella, Marvin and Window Nation offer custom double-hung window options, so homeowners can order specific sizes that fit their house and window needs. 

Which rooms are best for double-hung windows? 

Primary rooms in the house that can benefit from double-hung windows include the living room, bedrooms, and the kitchen or dining room. These are rooms where natural lighting and flexible ventilation are typically desired. In bedrooms or rooms on the second story, double-hung windows will often have tilt-in sashes to make cleaning easier. Additionally, those with small children or pets may prefer double-hung windows, as the top the sash opens from the top. 

Who can install single- and double-hung windows? 

Single- and double-hung windows should be installed by window companies, general contractors and remodelers, or by professionals from retailers like Home Depot and Lowe’s. 

DIY window installation is possible, but not recommended. Improper installation of windows may void warranties, which is why professional window installation is worth the cost.

The bottom line: Single-hung windows vs. double-hung windows 

Single-hung and double-hung windows both have pros and cons that homeowners should consider before purchasing. Homeowners should consider cost, ventilation needs, maintenance requirements and home design to help determine which window is best for them. 

Frequently asked questions 

Which is better, single- or double-hung windows? 

A mix of both window styles benefits different parts of a home. For those who prioritize cost, single-hung is the best option, but for those wanting flexible ventilation, double-hung offers the best airflow.

Willits notes that homeowners don’t have to choose between just one style of window. “Since aesthetically the two styles are very similar, many homes do actually use both styles together, often without being noticed from the exterior.” 

Are single-hung windows outdated? 

Single-hung windows aren’t outdated, and are most well-known for being a budget-friendly option for homes. They are a solid option for new-build homes or rental properties, since the designs are simple, effective and cost efficient. 

Which window type adds more home value? 

Double-hung windows with energy-efficient upgrades are the best option for adding value to a home. It depends on the quality of the materials and aesthetics of the home, but adding windows with energy efficiency and curb appeal can help. 

What is the least expensive style of window? 

Single-hung windows are typically the cheapest option.
