Q: What is the difference between a single hung window and a double hung window?
A: A single hung window is what most everyone considers to be the standard window. There is one moving part. Usually the bottom glass pane moves vertically up and down, and can oftentimes detach at the top from the frame for easy cleaning and ease of access. One of the benefits of single hung windows--and why they are so commonly used--is price. Typically single hung windows are 30-75% less than the double hung version of the same window.
Double hung windows have two moving parts. The bottom pane will move up and down and so will the top pane. This added moveable frame allows you to be able to change the air movement by closing the bottom pane and opening the top. It also gives you more control over the amount of air flow within your home.
A huge benefit to using double hung windows, especially on a second story, is that they are easier to clean. The top pane will lean in just like the lower half, allowing you to clean the outside of the glass easily.
One con of the double hung window is that by having more moving parts it adds to the number of places that can allow wind or water to enter. Just make sure you get a good, quality brand that will hold up well over time and ensure the energy efficiency of your home.
