Casement Windows – What to Know About the Different Types of Windows

The window style you choose will affect the resale value of your home and its energy efficiency. Here’s what to know about the different types of windows:

Bay and bow windows protrude from your wall, adding depth and dimension to a room. They’re also great for letting in natural light.

Energy Efficiency

Unlike sliding windows, casement windows open wide and allow plenty of air to flow into your home, keeping it cool in the summer and warm in the winter. This can reduce your energy bills significantly and help you save money in the long run.

Moreover, the locking mechanism embedded in their frames makes it impossible for anyone to break into your home through them from outside. This is why these windows are a great choice for homeowners with children and pets.

You can even opt for a triple-pane casement window that comes with krypton gas insulation for superior energy efficiency and lower energy costs. While this may increase your initial window replacement cost, you’ll be able to enjoy significant savings in the long run. You can also go for ENERGY STAR-certified windows that meet stringent government standards to help you save more on energy expenses while contributing towards a sustainable future.


A burglar is less likely to break into a home that has secure windows, especially if the windows aren’t visible from the street or your neighbour’s house. A casement window’s sash is locked securely into the frame and can’t be pushed open or pulled out, deterring unwanted intruders.

They are also more difficult to breach than double-hung windows, which have a moving sash that is prone to sticking and jamming. In addition, their tight seal enhances energy efficiency and keeps out cold air and rain.

Unlike double-hung windows that slide up and down, casement windows are opened using a crank handle. This makes them easier to operate and allows them to be placed higher on walls for a clutter-free look. They can even be joined together (mulled) to create larger openings for a more spacious design. Keeping your new casement windows clean and properly maintained will increase their lifespan.

Easy Operation

As one of the most versatile window replacement options, you can select from a variety of configurations. The side-hung casement, for example, is hinged on the left or right side and opens outward using a crank handle.

Alternatively, you can opt for an awning window. Similar to a casement window, these windows open outward but are operated by a manual crank instead of a handle. They also provide superior ventilation than other window types.

Since these windows open outward like a door, they need proper clearance to fully extend outward. Therefore, you should regularly trim shrubs and bushes around your home to prevent them from interfering with the operation of these windows. Additionally, these windows are exposed to extreme weather elements including wind, rain, and snow, and they may require extra maintenance. This is especially true if your windows are located on the coast or in areas that experience frequent rainfall. Luckily, there are plenty of waterproof coatings to protect your windows from the elements.


For areas of your home that need extra ventilation like the bathroom or kitchen, you can open casement windows to let in fresh air and passive cooling. Since they open wider than other window types, you don’t have to worry about snags or drafts.

When you get new casement windows installed, you can choose which way they’ll open by opting for FCL or FCR. The former means they’ll open toward the left, while the latter means they’ll open towards the right.

As a modern window replacement option, casement windows look stunning with any architectural style. Their clean lines and minimalistic design create a sophisticated appeal that can enhance your curb appeal and make your living space feel more spacious. They also come in different material & color finishes, so you can customize them to fit your needs. You can also opt for a flush casement window, where the crank lays flush with the frame when closed.
