What Are Casement Windows? A Beginner’s Guide

Posted on January 8, 2025

casement windows

When it comes to choosing windows for your home, the variety of options can feel overwhelming. Among these choices, casement windows stand out as a practical and stylish solution. This window type is one of the oldest and most common options throughout the U.S. Most homeowners have casement windows installed in some part of their home. 

If you have just started looking for new windows, this is the perfect place to get started. Here we talk all about casement windows and how they hold up against other windows. 

Whether you’re remodeling or building a new home, understanding what casement windows are and how they work can help you make an informed decision. 

What Are Casement Windows?

Most types of windows are differentiated based on how they are operated. Casement windows are a type of window hinged at the side, allowing them to swing outward like a door when opened. (Though some casement windows can be opened inwards also, depending on the installation.) These windows come with a crank or a lever, which you need to push to open and close them. 

Casement windows are often installed as single or paired windows and are a staple in both modern and traditional home designs. These windows are popular because they are durable and provide excellent ventilation, as they open fully to let in fresh air.

Their design is sleek, and they’re perfect for several areas of your home, be it the living room or kitchen. Because of their outward-opening design, they’re a great fit for hard-to-reach spots, like over a kitchen sink. (More on this later!) 

Why Should You Install A Casement Window In Your Home?

Casement windows are one of the most popular designs, thanks to the numerous benefits they come with. Here are some of the reasons why casement windows might be perfect for your home: 

Casement Window

Superior Ventilation

Casement windows offer unparalleled ventilation control for your home. Since the entire window sash opens outward, they can capture and channel breezes into your living space more effectively than most other window styles. By adjusting the angle of the open window, you can direct airflow precisely where you need it, making these windows particularly valuable in warm climates or in rooms that need extra air circulation.

Good Energy Efficiency 

Today, windows are not only looked at for ventilation but for energy efficiency too. Casement windows are great at energy conservation. When these windows are closed, it creates an exceptionally tight seal, and in some cases, even better than double-hung and sliding windows. 

This airtight fit prevents drafts and air leaks, helping maintain consistent indoor temperatures. The uninterrupted glass pane also maximizes natural light, reducing the need for artificial lighting. Homeowners might notice a reduction in their heating and cooling costs after installation.

Easier To Open and Close 

The innovative design of casement windows centers around a smooth crank mechanism that makes operation effortless. This user-friendly system allows for easy opening and closing, even in hard-to-reach places like behind counters or over kitchen sinks. The elimination of heavy lifting or sliding makes these windows accessible to users of all ages and physical capabilities, while still ensuring precise control over window positioning.

Enhanced Security 

Casement windows are a good choice for security reasons too. When closed and locked, these windows are extremely difficult to push open from the outside, providing peace of mind for homeowners.

Also, in modern casement windows, the security has been further increased through an advanced multi-point locking system integrated directly into the frame. Unlike simpler window designs that may have just one or two locking points, casement windows typically feature multiple securing points along the frame’s edge. 

Aesthetic Excellence

Casement windows offer a simple, practical design that works well with most architectural styles. The basic construction features clean lines and a larger glass area compared to double-hung windows, which can help rooms feel more spacious and bright. While not as ornate as some traditional window styles, casement windows can be customized with different frame materials and finishes to match your home’s existing look, whether modern or traditional.

Are There Any Problems With Casement Windows?

Like any window type, casement windows aren’t without their problems. 

Casement Windows

Compatibility with Air Conditioners

One of the most common concerns with casement windows is their compatibility with window air conditioning units. Traditional window AC units are typically designed for sliding or double-hung windows that open vertically, making it difficult to install them in a casement window.

However, there are solutions available. You can look for a casement window AC unit, which is specifically designed to fit the vertical orientation and side-opening style of casement windows.

Clearance Space

Since casement windows open outward, they require sufficient clearance outside. This can be a limitation in areas with restricted exterior space, such as balconies, walkways, or where landscaping might obstruct the window’s operation.

Maintenance Challenges

Cleaning casement windows, especially those on upper floors, can be a bit tricky. Because they open outward, accessing the exterior glass might require special cleaning tools or professional assistance.

Exposure to Strong Winds

In areas prone to high winds, casement windows may experience added strain when open. Strong gusts can catch the window and potentially damage the hinges or cause it to slam shut.

Modifications in Casement Windows

Despite the cons mentioned above, if you have chosen these windows for your home, they can be customized before installation. Casement windows can be tailored to meet specific needs and enhance their performance. Here are some popular modifications:

  • Double and Triple Window Glazing: Upgrading to double or triple glazing improves energy efficiency, noise reduction, and insulation. Triple glazing offers even better performance in extreme climates. Double glazing consists of two panes of glass with a layer of insulating gas in between, improving energy efficiency and reducing noise.
  • Low-E Glass: Low-emissivity (low-E) glass is coated to reflect heat, keeping your home cooler in summer and warmer in winter while reducing UV damage to furnishings.
  • Tinted or Tempered Glass: Tinted glass reduces glare and enhances privacy, while tempered glass increases safety, as it shatters into small, less harmful pieces upon impact.

Common Materials for Casement Windows

The material you choose for your casement windows can affect their performance, durability, and style. Here’s a quick look at the most popular options:

Vinyl

Vinyl casement windows are affordable, energy-efficient, and low-maintenance. They resist warping and moisture damage, making them a popular choice for many homeowners.

Wood

Wood offers a classic and luxurious look, perfect for traditional or rustic homes. While they require more maintenance to protect against rot and weathering, their timeless appeal is undeniable.

Aluminum

Aluminum frames are lightweight yet strong, ideal for larger windows. However, they can be less energy-efficient compared to other materials without proper insulation.

Fiberglass

Fiberglass is a durable, energy-efficient option that mimics the look of wood without the high maintenance. It’s a more premium material, but the longevity often makes it worth the investment.

How Much Do Casement Windows Cost? 

On average, casement windows cost from $500 to $1,100 per window, including installation. The cost of casement windows varies depending on several factors, including material, size, glazing options, and the complexity of installation. Here’s a breakdown of what to expect:

Material Costs: 

Vinyl is typically the most affordable option, followed by aluminum, wood, and fiberglass. Each material has different benefits in terms of durability, aesthetics, and energy efficiency.

Size: 

Larger windows or custom designs will naturally increase costs, as more materials and labor are required. However, large casement windows are not as popular because of the clearance they require for opening. 

Window Glazing Options: 

Opting for double-glazed casement windows can impact the cost but offers substantial benefits. 

Installation:

Professional installation ensures a proper seal and optimal performance, adding to the overall cost. Improperly installed windows can lead to air leaks, negating energy-efficiency benefits.
