When choosing new windows for your home, cabin, or backyard structure, one of the most common questions is: what’s the difference between single hung and double hung windows? While both styles look similar, the way they function and perform can make one a better fit for your project than the other.
Let’s break down the key differences so you can make an informed decision.
What Is a Single Hung Window?
A single hung window features two sashes — an upper and a lower — but only the bottom sash moves. The top sash remains fixed in place. To open the window, you simply lift the lower sash upward to allow air in from the bottom.
Key Benefits:
- Cost-Effective: Generally more affordable than double hung windows due to fewer moving parts.
- Energy Efficient: With one fixed sash, single hung windows tend to seal tighter, reducing air leakage.
- Low Maintenance: Fewer mechanical components mean fewer parts to clean or repair.
Best For:
Homeowners or builders seeking a simple, durable, and budget-friendly option for spaces where maximum ventilation isn’t essential — such as garages, sheds, or ground-level rooms.
What Is a Double Hung Window?
A double hung window looks similar to a single hung but offers two operable sashes — both the top and bottom can move. This design provides more flexibility for ventilation and cleaning.
Key Benefits:
- Enhanced Airflow: You can open both sashes simultaneously — warm air escapes through the top while cool air enters through the bottom.
- Easy to Clean: Both sashes typically tilt inward, making cleaning the exterior glass simple from inside the building.
- Versatile Style: Ideal for bedrooms, living spaces, and multi-story homes where accessibility and air circulation are priorities.
Best For:
Homeowners who value convenience, airflow control, and easy maintenance — or anyone looking for a window that balances performance with classic appeal.
Comparing Single Hung vs. Double Hung at a Glance
| Feature | Single Hung | Double Hung |
|---|---|---|
| Operation | Bottom sash moves only | Both sashes move |

| Cleaning | More difficult (especially upper sash) | Easier with tilt-in sashes |

Which Should You Choose?
If your goal is simplicity, cost savings, and efficiency, single hung windows are a great choice — especially for sheds, garages, or smaller buildings.
If you want flexibility, better ventilation, and easier cleaning, double hung windows offer superior convenience for everyday living spaces.
