Double-hung windows and single-hung windows are somewhat alike, but they contrast in a few fundamental ways. Single-hung windows are economical and energy efficient. Double-hung windows provide more airflow and are simpler to clean.

Single and double-hung windows are both typical in Denver homes, so you won’t have a problem finding a Denver window company that can manage the installation project for you.

Single and Double-Hung Windows: Defined

Single Hung Windows

A single-hung window possesses a single sash. When opening the window, the bottom sash lets the window go up while partly blocking the top sash. A single-hung window doesn’t tilt in and out.

Based on its features, a single-hung window is less practical and energy-efficient than a double-hung window. Numerous homeowners choose to purchase single-hung windows since they are very budget-friendly. Cost is the most crucial factor that tips the balance in favor of single-hung style windows.

Double-Hung Windows

A double-hung window has two workable sashes that go up and down in the window frame. The bottom or upper sash opens to increase ventilation. Moreover, both can open partly for maximum airflow. 

Cleaning double-hung windows is simple to clean. They pivot inward so you can reach the inside and outside panes from inside your home.

Differences Between a Double-Hung or Single-Hung Window

Though the design of single and double-hung windows is similar, there are some significant differences you’ll need to consider before picking one for your home. 


A single-hung window opens just at the bottom while a double-hung window opens at the top and the bottom. Double-hung windows deliver better airflow and ventilation. 

Cost Considerations

Naturally, a double-hung window costs more than a single-hung window, meaning higher installation and repair costs.

Costs will also vary based on:

  • Design
  • Size
  • Hardware
  • Frame material
  • Glass quality

Nevertheless, double-hung windows will always be pricier.

Energy Efficiency

If you want the best energy-efficient window, based on hardware and materials, a single-hung window may be your top choice. Single-hung windows could be a little more energy efficient since there are fewer moving parts, lessening the chance for air to get into your home. A double-hung window has more moveable parts and having a good seal at the top might be an issue.

When it comes to window installation, it’s vital to think about the seal around your window that aids in safeguarding your house from water and wind. Shimming is crucial to help provide a good seal between the frame and the weatherstrip which assists in keeping your residence protected.

Single-Hung vs. Double-Hung: The Bottom Line

Double-hung windows are easy to maintain and offer better ventilation but cost more and are less energy-efficient.

Single-hung windows are more economical and offer better insulation, but don’t provide less ventilation and are more difficult to clean. In the end, both window types are appropriate for most window projects. You must determine which one is best for your Denver residence.
