Single Hung vs. Double Hung Windows

Discover the difference between single hung and double hung windows to make the best decision for your home.

Choosing the right window for your home is crucial. Windows not only provide ventilation, they brighten your home and insulate it in the winter. Different types of windows, namely single hung and double hung windows, offer unique advantages to homeowners.  

What is the Difference Between Single Hung and Double Hung Windows?

Single hung windows, also known as single sash windows, have lower, operable sashes and upper, fixed sashes. That means the bottom part of the window can slide up and down while the top part remains in place. 

Double hung windows have two operable sashes, one on the top and one on the bottom for increased ventilation. Since heat rises, heat is able to escape the upper sash when it’s open, while cool air enters through the bottom sash, creating optimal conditions for comfort and relaxation.

Comparing Single Hung and Double Hung Windows

There are a few factors to consider as you decide between single and double hung windows. Aesthetics, cost, energy efficiency, maintenance, general location, and airflow can help determine which rooms are best suited for single hung windows and which might do better with double hung windows. 

Design and Aesthetics

The design of your windows can be customized to fit your aesthetic preferences.

While single hung windows often lack in variety, double hung windows offer homeowners greater style variety. The sashes can be designed to match, or they can have a different look to them. This decision is up to the homeowner.

Common Materials Used

At Clark Hall, we use only the best materials. Choose from custom steel, aluminum, or aluminum clad windows when designing your dream look. We are with you from the initial design process all the way through installation. 

Where to Use Single Hung Windows vs. Double Hung Windows

Single hung windows are commonly found on a home’s lower floor. The most common locations for single hung windows are bedrooms, offices, and kitchens, as the bottom sash allows air flow and increased ventilation through a room.  

Double hung windows are best in rooms that require increased ventilation, such as bathrooms, or on the second or third floor of a house. Since heat rises, having an operable top sash can help increase ventilation during the summer months, since it will undoubtedly help release trapped heat. 

Cost Comparison

Single hung windows are typically less expensive than double hung windows, since there are fewer moving parts. 

Energy Efficiency

Since there are fewer moving parts – and therefore less opportunity for gaps or air leaks – single hung windows may be a bit more energy efficient. When looking at energy efficiency, it’s important to select high-end materials, such as Clark Hall’s custom steel, aluminum, and aluminum clad windows.

Maintenance

Since you can open both sashes with a double hung window, double hung windows are typically easier to clean than single hung windows. 

Ventilation and Airflow

While single hung windows only allow air to escape and flow in through the lower sash, double hung windows permit air flow through both the upper and lower sash. This allows heat to escape through the top and air to flow in through the bottom, creating maximum comfort and ventilation. 

If you’re going to mix and match, Clark Hall suggests single hung windows on the lower floors of the house and double hung windows on the top floor to allow trapped heat to escape more easily. 

Safety and Security

When it comes to safety and security, single hung windows offer a bit of an advantage, given there is only a single moving part and thus only one point of entry. 

Size

Double hung windows are easier to customize, meaning that they are typically available in larger sizes than single hung windows. 

Mixing Types of Windows

Consider mixing and matching single hung and double hung windows to maximize ventilation and air circulation throughout your home. Install single hung windows on the lower floors for increased security and energy efficiency, and consider double hung windows on the top floor to help release trapped heat and allow for more creative aesthetic choices.

Frequently Asked Questions

Which is better for energy efficiency- single hung or double hung windows?

Single hung windows are generally considered more energy efficient because they have fewer moving parts and therefore typically have fewer opportunities for air leakage. However, custom-designed double hung windows may create tighter seals when closed. Clark Hall uses only the best materials, guaranteeing maximum efficiency regardless of your preference.

Are double hung windows worth the extra cost?

Double hung windows are worth the extra cost for many homeowners due to their versatility, easy maintenance, and better ventilation control. When it comes to comfort, double hung windows offer more options in terms of air flow, and the ability to open both sashes makes for easier cleaning and better maintenance. 

How do I maintain single and double hung windows?

Maintaining single and double hung windows involves regular cleaning of glass and frames, checking and replacing weather stripping as needed, lubricating tracks and rollers, and inspecting for any signs of damage or wear to ensure they operate smoothly and efficiently. Given that double hung windows have two operating sashes that can tilt both outwardly and inwardly, they are typically easier to maintain and clean.
