What Is the Difference Between Double Hung and Casement Windows?

If you are considering having new windows installed on your home, you will likely have several different styles to choose from. In fact, you may decide on multiple styles, as different areas of your home may benefit from windows that offer a variety of style and decor as well as functionality. Two of the most popular options among homeowners are double hung and casement windows, which both offer unique benefits. If you’re wondering how these two styles differ, read on.

Double Hung Windows

Double HungDouble hung windows are the most common type of replacement window in the U.S., in part because they are compatible with most home styles and come in a variety of shapes and sizes. They are loved for their classic look and the fact that they often have two vertically sliding sashes, so both the top and bottom can open, providing two levels of ventilation. This style also features dividers on the glass, called mullions, which either divide individual panes of glass or snap on for decorative purposes. Newer double hung windows have spring-mounted mechanisms that make them easy to open, and their tilt-out upper and lower sashes make cleaning a breeze.

Double hung windows are also highly energy efficient thanks to options in glass packs and installation methods that helps prevent heat transfer. They also can accept AC units and screens since they slide up and down.

Casement Windows

CasementCasement windows differ from other styles in that they open outward like a door to 90 degrees, allowing increased ventilation.  Casement windows operate using a hand crank. They are  ideal for locations that are hard to reach, such as over a sink in the kitchen.

The NEWPRO process was fantastic.

Window Replacement Project

Quality of the windows was superior to the others we looked at. Now, our windows tilt in, so it's going to be much easier to clean them.

Pool House Doors Project

Cold stays out in the winter. Cold stays in during the summer.

The best thing I love is the craftsmanship from NEWPRO. You'd never know we had the old door cut out because it was rotted from the New England weather.

The sales guy was very thorough and answered all of my questions. The guys that installed the windows were fantastic.
