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 the two operate.

A single hung window has a fixed top sash and an operable bottom sash that moves vertically. In a double hung window, both the top and bottom sashes are operable. 


Because both sashes are operable on a double hung window, you can just open the top sash by itself.  For in the cases where if you want fresh air that doesn’t blow directly on you while sleeping. 

Window Ventilation & Air Circulation

The second difference is the amount of ventilation and air flow you get from these two windows. Double hung windows offer maximum circulation by opening both sashes; cool, fresh air will flow in through the bottom while warm air flows out of the top.  

Window Cleaning & Maintenance

Most double hung windows come with tilt sashes, meaning the upper and lower sashes 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.

Window Costs

Lastly, because of the added features and functionality, double hung windows typically cost a little more than a single hung window of similar size.

Milgard offers the double hung operating style in Tuscany® Series and Quiet Line™ Series windows.

Double Hung vs single hung

I have a side of a house where there are four windows. Two on the second floor and two directly beneath on the first floor. I would like to have single hung on the first floor and double hung on the second floor. Do these windows look identical from the exterior? I want to make sure that the exterior look is the same.
