Casement vs Double-Hung Windows | Differences, Pros & Cons

When you’re thinking about window replacement, you’ll have a great many options available to you besides the traditional single-pane windows. There are a number of companies these days that provide all kinds of unique window styles that will add aesthetic appeal to your residence while also delivering increased energy-efficiency.

If you tend to be more of a traditionalist, double-hung Windows might be a good bet for you, because they retain that classic look from past eras, while incorporating modern energy-efficiency. If you’re looking for something new and exciting, casement windows might be just the ticket to transform your home. Below, you’ll find some information on both types of windows, so you can compare them and see if either one might be an option that really appeals to you.

Double-hung windows

Double hung windows are sometimes referred to as double-sash windows, because they can move both upward and downward within a frame. This type of window tends to be one of the most common windows chosen for replacements, in large part because they’re very easy to clean and very easy to operate.

They have remained an extremely popular choice for homeowners because they require low maintenance, they’re stylish, and they’re are always easy to operate. You’ll also be able to purchase them in a variety of materials and colors, so that you can establish just the look that you’re trying to achieve with your home.

Casement windows

These are sometimes referred to as crank windows, because it’s necessary to operate a crank in order to open them outward, generally about 45 degrees. These kinds of windows are great for ventilation, and for keeping an airtight seal on all sides to eliminate drafts. Casement windows are ideal for the bathroom, living room, sitting room, and almost everywhere throughout your household. Some of the benefits of case windows include providing a major boost to your energy-efficiency because of the airtight seal on all four sides.

Given the fact that all conditioned air will be kept inside and all unconditioned air will be prevented from penetrating to the interior, you can expect that your heating and cooling bills will begin to drop after installation. Casement windows can also provide a boost to your interior air circulation, because they have a smaller opening than double-hung windows. That means they will have a significant impact on the pressure difference between the inside and outside atmosphere. If it ever feels a little bit stuffy inside the house, all you have to do is crank open your casement window to welcome in a refreshing breeze.

Styles of the two windows

In terms of aesthetic appeal, both casement windows and double-hung windows will enhance the curb appeal of your residence, and make it more attractive in the neighborhood. Both types of windows can be purchased in either vinyl or wood, and are also available in a number of different colors. You can purchase add-ons or enhancements that will increase their functionality and visual appeal. If you’re someone who prefers a traditional look, double-hung windows are probably the better option for you, since casement windows represent an alternative capable of providing a more contemporary appeal.


With regard to maintenance, both types of windows require only minimal maintenance. When you are faced with the prospect of cleaning your casement windows, all you have to do is crank the window open so you can operate on both the exterior and interior panels. On the other hand, if you need to clean your double-hung windows, it’s only necessary to tilt them inward, so they can easily be washed and dried without stretching or assuming a dangerous position.

Energy Efficiency

If energy-efficiency is your top priority, you’ll probably want to choose casement windows over double-hung windows. That’s because casement windows have strong seals on all four sides that will serve to keep conditioned air inside and to eliminate drafts. However, if you’ve really got your mind set on double hung windows, you won’t necessarily have to sacrifice energy-efficiency. You can certainly purchase double-hung windows that, if installed correctly, can provide an airtight seal and deliver significant energy-efficiency benefits.


When it comes to durability, double-hung windows have a bit of an edge over casements. Given the fact that casement windows open outwards, they are slightly more exposed to inclement weather possibilities, and means that they’re more likely to degrade faster then most other types of windows. Since double-hung windows are secure inside their own frame, they tend to last longer than casement windows. That means if you happen to live in a persistently wet type of climate, you might be well advised to choose double-hung windows for their greater durability and resistance to weather elements.

Regardless of which window type you choose, there are a great many high-quality windows in today’s marketplace, and almost any of them will be good choices as replacement windows.
