Windows not only say a lot about your style, but they also add to the value of your home. When you look at the outside of a house, the windows are one of the first things that you notice. Having the right style window adds to your home’s curb appeal and can even lower your energy bills. Plus, replacing old windows is one of the most valuable improvements you can make if you want to increase your ROI (return on investment).

If you’re planning on getting new windows and can’t decide between double-hung vs. single-hung, how do you know which style to pick? Understanding the different window options on the market can help you make an informed decision. Learn about the difference between single-hung vs. double-hung windows here.

What’s the Difference Between Single-Hung vs. Double-Hung Windows?

Both window styles are vertical sliding and have an upper and lower sash. The sash is the lower panel on a window. On single-hung windows, the upper sash doesn’t move because it’s fixed in place. The bottom sash moves vertically. Single-hung windows are often the default choice for new home construction, condos, office spaces, and apartments.

On double-hung windows, you can open either the top or bottom sash. This means you can adjust your window for optimal airflow and better ventilation. Most window manufacturers, like Milgard windows, offer both single-hung and double-hung window styles.

So what’s the best choice between single-hung vs. double-hung? Deciding which is best for you depends on your personal preferences and your budget. Both styles have their advantages and disadvantages, after all.

Comparing the Benefits of Single-Hung and Double-Hung Windows?

Both single-hung and double-hung windows are vertical sliding windows with upper and lower sashes, but they differ in functionality. Single-hung windows feature a fixed upper sash that doesn't move, with only the bottom sash moving vertically. These are often the default choice for new constructions, condos, and apartments. In contrast, double-hung windows allow both upper and lower sashes to be opened and tilted, providing more versatile airflow and ventilation options.

Cost Considerations

When it comes to cost, single-hung windows generally offer a more affordable option, typically up to 20% cheaper than double-hung windows. This makes them cost-effective for large-scale replacements in older homes. Double-hung windows, while having a higher initial cost, may offer potential long-term energy savings and a better return on investment over time.

Energy Efficiency

Windows account for 25-30% of residential heating and cooling energy use, making energy efficiency a crucial factor. Both window types can be energy-efficient, but they have some differences. Single-hung windows have fewer moving parts, potentially reducing air leakage, and can be sealed with caulk for improved insulation. Double-hung windows, however, are more prone to air leaks over time due to more moving parts and cannot be sealed with caulk, requiring proper maintenance for optimal efficiency.

Ventilation and Airflow

In terms of ventilation, single-hung windows offer limited airflow options as only the bottom sash opens, which may not provide adequate ventilation in moisture-prone areas like bathrooms. Double-hung windows, on the other hand, offer superior ventilation capabilities. They allow for the creation of a cross-breeze by opening both sashes, making them better suited for rooms prone to moisture buildup.

Maintenance and Cleaning

Maintenance considerations differ between the two types. Single-hung windows are generally easier to maintain due to fewer moving parts but can be challenging to clean, especially on upper floors. Double-hung windows, while potentially requiring more frequent maintenance such as lubricating tracks, offer the advantage of both sashes tilting inward, making cleaning easier, particularly for upper floors.

Style and Aesthetics

In terms of style and aesthetics, single-hung windows offer a classic look that may be more suitable for older, traditional homes, though they have limited style options compared to double-hung windows. The increasing popularity of double-hung windows has led to a wider variety of styles and colors, and they can often mimic the look of older windows while providing modern functionality.

What About Older Homes?

If you have an older home, the first thing you might want to upgrade is the windows. Drafty windows allow air to escape, raising your heating and cooling costs. You have several options when it comes to fixing windows in an older home. You can repair old windows or replace them.

If you plan on replacing your old windows, single-hung windows may look more historically accurate and you may already be used to single-hung windows as the more common window type in older homes. However, the benefits of double-hung windows should be considered especially because they are made to look no different but have unique operating styles.

Finding the Right Window Style for Your Home

When it comes to single-hung vs. double-hung windows, how do you know which style to choose? Both single-hung and double-hung windows have their merits, and the best choice depends on your specific needs, preferences, and budget. When deciding between single-hung and double-hung windows, consider several key factors that will influence your decision. Your budget will play a significant role, as single-hung windows typically offer a more cost-effective solution for those working with financial constraints. However, it's crucial to balance initial costs with long-term value and energy efficiency.

The age and architectural style of your home should also guide your choice. While single-hung windows might provide a more historically accurate look for older homes, many modern double-hung styles can effectively mimic traditional aesthetics while offering enhanced functionality. Climate and ventilation needs are equally important considerations. If you live in a humid environment or have rooms prone to moisture buildup, such as bathrooms or kitchens, the superior ventilation options provided by double-hung windows might be particularly beneficial.

Your willingness and ability to perform regular maintenance should also factor into your decision. Double-hung windows, while offering easier cleaning options, especially for upper floors, may require more frequent upkeep due to their additional moving parts. Energy efficiency goals should be weighed carefully. Although both window types can be energy-efficient when properly installed and maintained, double-hung windows may offer better long-term savings despite higher initial costs.

Lastly, consider your desire for customization. If you're looking for a wide range of styles and colors to match your home's aesthetic, double-hung windows typically offer more options. Ultimately, the best choice will depend on balancing these factors against your specific needs and preferences. For optimal results, it's advisable to consult with a window professional who can provide tailored advice based on your home's unique requirements and help you navigate the selection process with confidence.

Single-hung windows offer a cost-effective solution with a classic look, while double-hung windows provide superior ventilation, easier cleaning, and potentially better long-term value. For the best results, consult with a window professional who can assess your home's specific requirements and guide you through the selection process. They can provide tailored advice on which window style will best suit your home's architecture, your lifestyle needs, and your budget constraints.

Remember, investing in quality windows is not just about immediate aesthetics – it's a long-term investment in your home's comfort, energy efficiency, and overall value. Take the time to weigh your options carefully, and don't hesitate to seek expert advice to ensure you make the best decision for your home.
