Two double hung windows as seen from a home's exterior

Double vs. Single Hung Windows

July 24, 2025seanadmin

Have you ever had to wrestle with a window just because it won’t budge, or felt like a circus performer while cleaning your upstairs window? Choosing the right type of window can make your everyday life easier and safer, while also saving you a substantial amount of cash. 

 

Among the many options available in the market, two window styles have always been prominent: single-hung windows and double-hung windows. But which one is best for you? Both single and double-hung windows offer a timeless aesthetic but differ in cost, upkeep, and functionality. Whether you value budget-friendly solutions or easy cleaning and extra airflow, after this guide, you will be able to make a decision that feels just right.

What Defines Single-Hung And Double-Hung Windows?

Single-hung windows are known for having a fixed upper sash, with only the lower sash moving up and down. The simplicity behind this design is the reason behind their affordability and energy efficiency. Fewer moving parts mean tighter seals and protection against drafts. 

 

On the flip side, double-hung windows allow for both their upper and lower sashes to move. This allows these windows to be more flexible, improving ventilation and making it easy to clean, especially the ones with tilt-in sashes that let you easily reach exterior glass from inside your home. Thus making it perfect for multi-story houses. 

Key Comparison Factors

Ventilation And Airflow

Single-hung windows can only provide a limited amount of ventilation since only the lower sash can be opened. It is the ideal window for spaces that require minimal airflow, such as areas with controlled temperature or small rooms. Double-hung windows offer better circulation as both of their sashes can move, thus allowing warm air to escape through the top while cool air comes in from the bottom. 

Ease of Cleaning And Upkeep

With fewer moving parts and a simple design, single-hung windows are much easier to maintain in the long run. However, cleaning the exterior of these windows can be challenging, especially if they are installed on the upper floor. Most double-hung windows come with tilt-in sashes, which let you clean both sides of the glass from the inside. Albeit simple, it helps in saving a lot of time and is perfect for multi-story homes.

Energy Efficiency And Sealing

Because of their single movable sash, single-hung windows offer a much tighter seal. This allows it to improve your home’s energy efficiency as it can reduce drafts and heat loss. Thus, greatly reducing heating and cooling costs. 

 

Whereas Double-hung windows have more moving parts. This slightly increases the potential of drafts and heat/cooling loss. However, it can be mitigated by proper installation and quality material to help minimize energy loss. 

Cost And Installation

As mentioned, because of their simple mechanism, single-hung windows are more affordable and tend to have lower installation costs, which makes them perfect for budget-conscious homeowners. 

 

Comparatively, double-hung windows tend to have more upfront cost, but balance it out with extra convenience and flexibility. While simple, these extra features are excellent for homeowners who have multi-level homes. 

Framing the Final Decision

Both single and double-hung windows have their strong point — one offers simplicity and savings, whilst the other provides flexibility and convenience.
