What to know about single-hung windows before making a buying decision about them

Single-sash windows are the most common and can be seen virtually everywhere, from humble single-story homes to apartment buildings and commercial premises. Their classic design and simple construction make them an economical choice for homeowners who seek a quick and reliable solution to update their old windows. Nevertheless, if the price is not your top priority, you may want to consider double-hung windows that are also open upwards but offer better security and ventilation. The pros and cons of these two most popular window styles, their characteristics, and distinctive features are approached in this article. Read on to learn about single-hung window replacement costs, sizes, frame materials, upkeep specifics, and other details required to make a well-informed buying decision.

What to know about single-hung windows before making a buying decision about them

What is a single-hung window?

Single-hung is a standard square window with upper and lower sashes that physically and visually separate the unit. The upper pane is always stationary, while the lower can move up and down for better ventilation. When the window is opened, the view of the top sash is partially covered. Besides, single-hung units can only be opened halfway from their bottom part, with no tilted position like in the hopper or tilt & turn windows. This construction limits the airflow and might pose a danger to kids and pets. That is why single-hung windows are commonly replaced with double-hung ones in family-occupied buildings. This type of window is also not recommended to install on upper floors as it might be troublesome to clean the exterior of the top sash. 

The standard single-hung window sizes

The standard size of the window is usually mentioned in the unit listed specifications and label. However, a few manufacturers may use their size notation numbers. To avoid miscomprehension, consider consulting store assistance before making a purchase. Single-hung windows usually have the standard width of 24, 28, 32, and 40 inches, while their height goes from 36 to 72 inches with the intermediate marks of 44, 52, 54, and 62 inches.

What are the pros and cons of single-hung window installation?

There is nothing more conventional in American homes than single-sash windows with wooden frames. Many people accept this window type as a relic of the past, while others are perfectly happy with this budget-friendly and simple functioning solution. If you're in two minds if this window type is worth your investment, the following overview of its pros and cons will definitely ease your agony of choosing.


  • Cost-efficiency

Single-hung windows remain a top choice for hundreds of thousands of homeowners countrywide mainly because they're cheap and easily serviceable. Their construction does not comprise too many moving parts, so they're cheaper to install and maintain. Besides, they're 20% cheaper than their double-pane 

  • Proper insulation

Single-hung windows come with a fixed sash that remains properly sealed the whole service life. The movable part can be weather-stripped for a cold season to maximize insulation. The half-fixed construction makes single-hung units better resistant to weathering and wear and tear. 

  • No protruding parts

Single-hung windows are commonly installed on the first floor along a patio or inner court as they do not protrude while opened. In contrast to awning and casement units, single and double-hung ones are compact and don't get in the way, making them best for high-traffic areas. 

  • Laconic design

Single-hung windows have a simple construction that is not overloaded with moving parts. That is why they look appropriate in any house room and interior design. 


  • Limited airflow

Only one sash is operable in single-hung windows, so they cannot promote enough air circulation. That is one of their major drawbacks compared to double-hung windows. Single-sash windows are not recommended in bathrooms as a lack of ventilation can cause moisture build-up.

  • Safety issues

The lower sash of a single-hung window is moveable and is opened vertically, creating an unsecured opening that can become a trap for pets and kids. Nevertheless, an opening of the single-hung windows is commonly not large enough to be used as an emergency exit.  

  • Cleaning difficulties

Due to their construction that does not imply tilting inwards, single-hung windows are complicated to clean from inside the house, especially regarding their upper part.

Single-hung windows vs. double-hung windows - Which one is the best?

Location Family rooms, dining rooms, kitchens, and living rooms. Bedrooms, living rooms, kitchens, and bathrooms.
Energy efficiency Single-hung windows have high-performance standards as they have only one operable sash while another remains fixed and does not require additional sealing. The double-hung windows' performance has a tendency to worsen over time as they have two moveable sashes, the sealant of which wears out.
Safety There are two parts of single-hung windows - a fixed and a moveable one which is opened from the bottom. It creates safety risks for kids and pets who can potentially crawl through the opening.

Installation & replacement Single-hung windows replacement requires less equipment and skills to be performed than double-hung one.

Ventilation This window type does not ensure enough room ventilation as only a bottom sash can be opened to let air in. This window type allows both sashes to be opened to let fresh air in through the bottom and release warm air through the top.
