When replacing or installing new windows, homeowners often face a common dilemma: single-hung or double-hung windows? Both styles have distinct advantages, but the right choice depends on factors like ventilation, maintenance, energy efficiency, and budget. In this guide, we’ll compare both window types, breaking down their pros and cons to help you decide which option best suits your home. Beyond these two traditional styles, there’s also a growing alternative—tilt and turn windows. Will they challenge the long-standing dominance of single and double-hung windows?
Understanding the differences – Single-Hung vsDouble-Hung
Each home is a different story. As a homeowner, you want what’s best, and when choosing between Single-Hung or Double-Hung windows, the final decision can be tricky. Let’s look at the main characteristics of both window types and see what advantages and drawbacks each of them brings.
What is a Single-Hung Window?
A single-hung window, also known as a single-sash window, features a lower, operable sash and an upper, fixed sash. The bottom part of the window slides up and down, while the top part remains stationary. Single-hung windows provide ventilation through the bottom sash. This design makes single-hung windows less efficient and practical than their double-hung counterparts. However, their simplicity and affordability make them a popular choice among homeowners.
Single-hung windows are a classic choice and are prevalent in many home designs, including residential spaces, office spaces, and various home styles. You can often see them in homes that lean more toward traditional architecture, such as those with a historic aesthetic or craftsman style.
Pros and Cons – Single-Hung Window
Single-hung windows have several advantages. They are typically less expensive than double-hung windows due to their more straightforward design and fewer moving parts. Some argue that double-hung windows are less susceptible to air infiltration or leakage because the upper sash remains fixed and cannot develop looseness like a moving sash.
However, single-hung windows also have their drawbacks. If the upper sash breaks, a glazier must repair the window. They are also more challenging to clean based on location, especially if you want to clean their exterior. You would have to go outside or hire a window cleaning company, mainly if you live on the upper stories.
Despite these drawbacks, single-hung windows are a standard style often used in constructing various spaces due to their affordability and traditional aesthetic. They are a testament to the saying that sometimes, less is more.
What is a Double-Hung Window?
A double-hung window, also commonly referred to as a double-sash window, is a type of window that features two operable sashes that slide up and down. Both the top and bottom parts of the window can be moved, providing a higher level of versatility compared to single-hung windows. Double-hung windows are an excellent choice for two-story homes, as they allow warm air to escape out of the top sash while cool air from the outside can flow through the lower sash opening, providing increased comfort.
Moreover, double-hung windows can tilt in for easy cleaning, allowing homeowners to clean the exterior without special equipment or needing a window cleaning company. This makes them a common choice for many home designs. Looking around your neighborhood, you will see them often used with a colonial, traditional, or Victorian aesthetic and design.
Pros and Cons – Double-Hung Windows
The first argument that homeowners often bring is that they are easier to clean due to their tilt-in design, which allows the window’s exterior to be cleaned from inside the house. They also offer better ventilation because you can open both the top and bottom sashes to allow air to flow into and out of the home. Also, homes with small children can benefit from the safety of double-hung windows, as they allow you to open the top sash while keeping the lower sash closed. This design facilitates airflow and reduces the risk of accidents.
That’s for the advantages. Now let’s talk about some drawbacks. They are typically more expensive than single-hung windows due to their increased functionality and the additional moving parts involved in their construction. Despite these potential drawbacks, double-hung windows remain popular due to their versatility, ease of cleaning, and improved ventilation. Thanks to the balance between functionality and a plethora of design choices, it makes them a worthwhile investment for many homeowners.
Which type is better for energy efficiency – Single-Hung vsDouble-Hung?
We’ve discussed each window type’s main advantages and drawbacks in the context of regular cleaning, maintenance, and air circulation. The conclusion is that in many cases, double-hung windows win against single-hung type. They provide better ventilation options with their tilt and turn features and easier cleaning and maintaining in perfect shape. But what about energy efficiency? Which type performs better? Many experts point out that double-hung windows are engineered with energy efficiency in mind (but there is a catch). More moving parts can potentially lead to issues with sealing at the top edge, impacting their energy efficiency over time.
But there is another solution that takes the US market by storm.
