Single-Hung vs Double-Hung Windows: What’s the Difference?

    Single-Hung vs Double-Hung Windows

    If you’re reading this post I’m guessing you’re thinking about replacing your old drafty windows with new energy efficient windows and you want to know your options. 

    Here are a few things you need to consider:

    1. Energy efficiency
    2. Style
    3. Price

    When you’re dealing with Inside Out Home Improvement you have options of style, features and color and it can be overwhelming that’s why I want you to know the difference between the two most common residential windows available, single-hung and double-hung windows.

    I know several of you believe that single-hung and double-hung refers to the number of window panes in the window but it’s really referring to the operating sashes.

    Both styles have two sashes, a top and bottom sash. However, on a single-hung window only the bottom sash operates, goes up and down, the top sash is stationary. On a double-hung window both, top and bottom sashes, go up and down.

    I hope this clears up one of the differences between the single-hung and double hung windows.


    Single-hung windows can be more difficult to maintain and clean because the bottom sash operates and the top sash is stationary so you have to clean your windows from both, the inside and outside of your house.

    While cleaning the first floor windows from the outside is bad enough cleaning the second story windows is much more difficult. That’s why maintaining the second story windows doesn’t happen as often as it should.

    On the other hand double-hung windows are much easier to maintain and clean because both sashes tilt inward so you can clean both sides of your windows while standing inside your home. This eliminates the need to go out side and climb a ladder just to clean your windows.


    Double-hung windows offer more ventilation because you can open the top and bottom sashes as opposed to the single sash on the single-hung window. When your home is well ventilated it helps to eliminate mold and mildew by allowing the air to flow through your home, therefore making your home healthier and more comfortable.

    Energy Efficiency

    Whenever you have moving parts on a window you run the risk of an insecure air seal. Insecure and/or poor air seals are responsible for over 40% of the energy you use to heat and cool your home.

    This is the main reason homeowner’s spend the money to upgrade their windows to energy efficient windows.

    The cheap double hung vinyl windows that are available through several window companies are made of poor quality vinyl and won’t always seal properly at the top edge or where the two sashes meet, this will contribute to higher energy costs than the single-hung window and resulting in giving the double-hung window a bad reputation.

    This is why most people believe the single-hung window is more energy efficient but in reality the premium high quality vinyl energy efficient double-hung window that are offered by Inside Out Home Improvement is more energy efficient.


    It pretty much goes without saying that single-hung windows can cost about 50% less than the double-hung windows, but this really depends on the window company you’re talking to.

    I know of a few companies who are selling double-hung vinyl windows for around $1500 each and other companies sell single-hung vinyl windows for around $1,000 each. I know what you’re thinking and I wouldn’t buy windows from those companies either.

    Just like I wouldn’t buy windows from a company that’s selling double-hung windows for less than $300-$400 each, you know they are selling an inferior product especially if they’re saying “Free installation”. How can you trust anyone who doesn’t pay their installers a fair competitive wage?
