Casement Vs. Double Hung Windows: What’s The Difference?

Replacing your windows is a great way to enhance the comfort, appearance, and energy efficiency of your home, but some homeowners have trouble deciding which style of replacement windows to install. Below, we take a look at two of the most common window styles—casement and double-hung—in terms of form, function, and features, so you can feel more confident in deciding which windows are right for your home.


Casement windows are hinged along the side and open by swinging outward like a door. They are often opened and closed by way of a crank mechanism, but other models simply push out to open and pull in to close. Either way, casement windows are known for their ease of operation, making them a good window choice for hard-to-reach areas. Casement windows also offer exceptional home security, as they feature hook-shaped locks embedded in the frames.

Because casement windows can be opened up to 90 degrees, they offer more versatility than hung-sash windows when it comes to catching a cross breeze. In addition to bringing in fresh air, this can also help your home stay cooler so you don’t have to rely as much on electric fans or air conditioning. When it comes to aesthetics, casement windows pair well with older style houses, as well as homes that are more contemporary. Models with muntins or grilles can impart a colonial or French provincial design element while keeping the panes of glass unobstructed offers a more contemporary vibe while also enhancing views.

WHAT IS A Double-Hung Window?

The most common window style on modern homes, double-hung windows feature two moveable sashes. Most often, these windows are opened by lifting the bottom sash upward, however, the top sash can also be pulled down to create an opening on the top as well. This unique style offers versatility when it comes to ventilation, as it allows you to achieve a cross-breeze effect with just one window. When both sashes are opened just a few inches, cooler air is drawn in through the bottom opening, while warmer air from inside the home rises and is pulled out through the top.

Double-hung windows are also commonly touted for being easier to clean than other window styles. Most double-hung window models feature “tilt-in” sashes that fold inward, allowing you to clean both sides of the glass from inside your home. This is especially helpful for cleaning the outsides of windows on second or third stories, which would otherwise require you to climb a ladder to complete the job.
