While there are tons of different kinds of windows out there, single hung and double hung are the most common and recognizable. If you’re about to begin a window replacement for your Federal Way, WA home, you’re probably considering single or double hung windows. Learn more about their differences so you can choose wisely.  

Both single and double hung windows slide vertically, and have upper and lower sashes. In fact, double and single hung windows can actually look the same from a distance. The main difference between these two kinds of windows is in how the sashes move. Only the bottom sash moves on single hung windows, but both the top and bottom sashes move in double hung windows.  

Double hung windows are becoming the most common window type for one main reason: they’re easier to clean. Double hung windows move up and down and tilt in and out. This tilting allows them to be cleaned from inside the house.  

The ability to open both the upper and lower sash on a double hung window is also helpful because it boosts airflow, and allows you to customize the airflow in your home and therefore make it a more comfortable temperature. Double hung windows allow you to create a small circulation effect by opening both the upper and lower sashes only halfway, or only have the top or bottom parts of the window open at one time. It’s also important to remember that double hung windows might be a safer choice for homes with children as only having the top sash open can help prevent little kids from falling out.  

However, double hung windows are thought to increase air leakage because they have more openings, and can also be more expensive than single hung models.  

Single hung windows, on the other hand, are older than double hung, and are often preferred for a historic or traditionally styled home. Single hung windows are also more cost effective than double hung. Single hung windows are generally more airtight than double models as the upper sash is fixed and doesn’t loosen over time. It’s also easier to caulk and weather seal a single hung window for even more energy efficiency.  

Both single and double hung windows are a good option for your home. Which one you choose really depends on what your preferences are. If you want to be able to open both window sashes or remove the sashes for cleaning, go with double hung. But if those features aren’t as important to you as cost, single hung might be the better option.
