Single Hung vs. Double Hung Windows

Share This


Single and double hung windows are two of the most popular – and traditional – windows on the market.

They are a solution for adding both natural light and ventilation to any room and come in a wide variety of sizes – from small bathroom or hallway niches, to large windows which serve to highlight the outdoor landscape. The differences between them comes down to price and function.

What is the difference between a single hung and double hung window?

Single Hung Windows – these windows consist of two window sashes. The upper sash is permanently “fixed,” so it doesn’t move, and the lower sash can be moved up and down.

Double Hung Windows – these windows also have two window sashes but in this case, the top sash can move down and the bottom sash can move up, which provides increased air-flow.

There are advantages and disadvantages to each window type, but the four things you will see mentioned most often are in regards to price, ventilation quality, energy efficiency, and cleaning.

In general, a single hung window will be cheaper than a double hung window. They involve less movable parts and, over the lifetime of the window, they will require less maintenance.

When you really break down the cost analysis in terms of energy efficiency (which we’ll discuss later), you will benefit from an increase in energy savings, varying on the climate and time of year.

Double hung windows offer better ventilation than their counterparts because you have more options to choose from. Because the top sashes can be lowered, you can keep your windows open when nearby sprinklers are on, or to benefit from a slight breeze on a still day.

Energy Efficiency
If energy efficiency is a top priority for you, then you should probably stick with single hung windows or invest in the highest quality vinyl double hung window you can afford.

Any window with movable sashes will have a little extra room for unconditioned air to move into your conditioned home, or visa versa (warm air tends to migrate towards areas with cooler air). On average, a single hung window’s fixed sash will provide the best weather seal. A double hung window has the potential to be slightly leaky all the way around.

A high-quality vinyl window frame will help to reduce energy loss. Whichever window you select, make sure it has an Energy Star label.

This is probably the number one reason why home owners prefer double hung windows. The sashes can be tilted in, which make them very easy to clean. However, if you prefer single hung windows, ask us about single hung tilt windows.

They can also help to make the window cleaning process easier for you, even without two tilting sashes.

If you are in the middle of a remodel, or are interested in replacing your home’s windows, it’s important to visit a vendor’s showroom to see the wide variety of options available and have the chance to try out various window type.
