Single-Hung vs Double-Hung Window Styles

Choosing windows for your house can seem like a complicated process since there are quite a few decisions you will have to make during the process. However, one of the earliest and most important decisions is choosing your window style. Two of the most popular window varieties that both have a similar shape are single-hung and double-hung windows.

What are the differences between the two if they don't differ dramatically based on their size or shape? Then, we compare all of this and lay out the differences so that you can find the perfect windows for your home.

Single-Hung vs Double-Hung Window Styles

What are single-hung windows?

Single-hung windows can also be called single-sash windows. The sash of a window is the part that holds the glass in place. In a single-hung window, only one of the window's sashes can move. Typically it is the lower sash that is operable. The upper sash is fixed in place. That means that the bottom portion of the window is the only one that can slide up and down on its sidetracks. 

What are double-hung windows?

Similar to a single-hung window, double-hung windows also go by the name double-sash windows. However, instead of only having one operable sash, both window sashes in a double-hung window can slide up and down. 

Single-hung and double-window comparison

Choosing between single- and double-hung windows might not seem as straightforward as choosing between double-hung and awning windows or something similar. However, there are some clear differences.

One of the primary differences you will notice right away while shopping around for windows is the price differences you will see between these windows within the same brand. Single-hung windows will almost always be more expensive than double-hung windows. There are fewer moving parts in a single-hung window, meaning they are easier to manufacture. 

The primary difference in how these two windows function in the home has to do with ventilation. Since only the bottom sash can open in a single-hung window, it can only ventilate the room through its lower half.

A double-hung window with both of the sashes partially open has the capacity to ventilate through both of the spaces. The windows will overlap and you still won't be able to open the entire window portal. However, having this gap actually ends up working in favor of ventilation. Since heat rises, the heat will primarily try to escape out of the top portion of the window. That leaves the bottom part open for cool air to flow inside more easily.

When Should I Choose Single-Hung Windows?

  • Single-hung windows are better suited to lower floors since they typically require less ventilation since heat rises to the upper floors. It is also easier to clean single-hung windows when you can stand on the ground or a patio to clean them from the outside.
  • If you want to absolutely maximize your home's energy efficiency, you should choose a single-hung window. Since they have fewer moving parts, they can be slightly more efficient than double-hung.
  • Choose single-hung windows if you want a more affordable option when buying replacement windows.

When Should I Choose Double-Hung Windows?

  • Choose double-hung windows if you want to maximize ventilation on the upper floors of your home.
  • Double-hung windows tend to be easier to clean since they often have tilt-latches that allow you to open the bottom and top sashes from inside your home.

Single- and double-hung windows are similar in many ways. However, there are significant differences in the way they operate and other differences based on their layout. If the choice still isn't clear to you, it is worth talking to your local window and door experts.
