If the time has come to replace your home’s windows, you’ve got a lot of decisions to make. After all, window replacement is a big investment and you want to get it right.

One of the most important decisions is the window style you choose. Two common types of residential replacement windows are casement and double-hung. Here are the basics about these two popular window styles.

What is a Casement Window?Casement Windows Bay Window

Casement windows are usually tall and narrow with hinges on one side of the frame. The unhinged side can be opened for ventilation with a cranking mechanism. These windows come in a number of configurations including single, double and also as part of bay or bow windows.

Casement windows are adjustable and can be cranked out fully for easy cleaning from the inside.  A related window type is an awning window which is essentially a casement window on its side. These usually have short sides and long tops and bottoms.

A double-hung window is, not surprisingly, actually two windows designed to work in tandem with each other, moving up and down in the frame. Some allow you to move both the upper and lower sashes while others only let you move the bottom. Newer double-hung windows allow the frames to “tilt in” for easier cleaning.

Practical Considerations for Casement or Double-Hung Windows

If you want to switch out the style of window you currently have – for instance, replace casement windows with double-hung windows – be sure to ask your contractor if the new style will be in compliance with the building codes in your area. For instance, in many cities, there are residential egress requirements that a firefighter in full gear must be able to fit through the window. Be sure any changes that you make meet your local building code.

Casement and Double Hung WindowsSwitching styles may also demand some additional construction work to make the window opening conform to the news style so keep that in mind when you are planning your replacement window project.

Some windows work better in certain locations than others. For instance, if you have a window over your kitchen sink or similar spot where it’s necessary to reach over something in order to open the window, a casement window with a crank mechanism makes more sense than a double hung window.

Historic homes usually get double-hung windows to stay in keeping with the building style of the time. Another practical consideration – casement windows cannot accommodate a window air conditioner so if you need a window air conditioner, you’ll want to stick with a double-hung window.
