Your Guide to Double-Hung vs Single-Hung Windows | NEWPRO

A Guide to Double-Hung vs Single-Hung Windows

When researching replacement windows, two popular types pop up: single-hung and double-hung windows. Both types are commonly installed because they are practical, durable, versatile, and aesthetically pleasing. 

Double-hung and single-hung windows share several similarities but also have key differences. One main divide is that a single-hung window has fewer moving parts than a double-hung window.

When you partner with NEWPRO Home Solutions for your replacement windows, you get energy efficiency, curb appeal, and style rolled into one. If you desire a beautiful, energy-efficient exterior, call NEWPRO today to get started on your new windows.

In this guide, we will explore the features and functionalities of single-hung versus double-hung windows so you can decide which is best for different parts of your home.

What Is a Single-Hung Window?

Single-hung windows typically have a fixed upper sash and an operable bottom sash. They are also known as “single-sash” windows because they have one moveable sash that slides up and down. They offer less air circulation than double-hung windows but don’t cost as much.

Pros and Cons of Single-Hung Windows

Single-hung windows offer more ventilation than most window types. For instance, they offer more ventilation than inoperable picture windows or specific awning window designs. However, single-hung windows don’t provide as much ventilation or airflow as double-hung windows.


Installing single-hung windows in humidity-prone spaces such as bathrooms can increase moisture levels. Mold and mildew thrive in high-humidity spaces, so installing a single-hung window in a bathroom may not be a good idea.


Besides limited ventilation compared to double-hung windows, cleaning single-hung windows from inside a building can be challenging. Most single-hung windows don’t have the tilt function for easy cleaning, so when it’s time for window cleaning, you’ll have to go outside.

Energy Efficiency

Single-hung windows are potentially more energy-efficient than double-hung windows. They have fewer moving sections, which minimizes air leakage in some homes. However, air infiltration can be mitigated in most types of windows if the installer does a proper job.

With NEWPRO, you get premium window installation services and top-line products that enhance energy efficiency, saving you money. Our ENERGY STAR- rated windows are gorgeous, durable, and stylish. Contact NEWPRO today to get the right windows for your beautiful home.

What Is a Double-Hung Window?

A double-hung window features two operable sashes that slide up and down in the window frame. These window types come with an upper and lower sash that can be slid or tilted. Double-hung windows are also referred to as double-sash windows.

Pros and Cons of Double-Hung windows

A large percentage of homeowners and building contractors prefer the latter over single-hung windows. Double-hung windows offer better ventilation and increased airflow, especially when strategically installed around the home.

Enhanced Air Circulation

When you open both window sashes, hot air escapes through the top sash, while the bottom sash allows cool air to flow in. This is especially handy when you want to give the HVAC system a break on cool spring or fall days. Single-hung windows don’t offer this functionality because they have only one moveable window sash. With a double-hung window, you can quickly air out a musty or stuffy room and let in fresh air.

Easy Maintenance

Aside from improved air circulation, double-hung windows are easier to maintain. You tilt the sashes to clean them, offering a comfortable wipe-down. This window style is great for upper levels or floors, especially when it comes to cleaning and maintenance. 


Because they’re easier to maintain, double-hung windows offer more versatility when it comes to where to install them. They are among the best windows homeowners choose for their window replacement projects.

Single or Double-Hung Window?

Both single-hung and double-hung windows are popular options with American homeowners. They are versatile, functional, and energy-efficient. Single-hung windows cost less than double-hung windows, but they offer less ventilation. Single-hung windows are also not advisable in confined, high-moisture areas like bathrooms. 

In the double-hung vs single-hung windows debate, each kind has numerous positives, but it ultimately depends on your preference and what suits your home. Remember, your home windows reflect your style and taste while boosting your home’s curb appeal. 

Whether you prefer single- or double-hung windows, when you partner with NEWPRO, you’ll get the best windows for your beautiful home.
