Single Hung vs. Double Hung Window: What’s the Difference?


Shopping around for windows and unsure what the difference is between a single hung versus a double hung window, or which one is best for your home? We can help you understand the key differences between these two types of windows. 

Window Operation

The main difference between a single hung and a double hung window is how they operate.

What is a single hung window?

single hung window has a fixed top sash and an operable bottom sash that moves vertically.

Window Ventilation & Air Circulation

The next key difference is the ventilation and air flow you can get from these two window types. Double hung windows offer maximum circulation when both sashes are open; cool, fresh air will flow in through the bottom while warm air flows out of the top.

Window Cleaning & Maintenance

A key advantage to double hung windows is ease of cleaning. Double hung windows come with tilt sashes that allow the upper and lower sashes to tilt inward. This allows both the interior and exterior glass to be cleaned from inside your home. This is especially helpful for second and third floor windows.
