Casement windows are hinged on the side and usually open outwards with the use of a single-lever latch. They are designed with one or more side hinges to save you from lifting or pulling the window open. You can choose casement windows that come with a smaller top window, otherwise known as an awning window. The awning window will be hinged at the top and opened in the same way as the main casement window.

uPVC (unplasticized polyvinyl chloride) casement windows are ideal for anywhere in the home, but they are often found in hard to reach areas, such as above the kitchen sink. They come in coloured and woodgrain finishes and are one of the most popular window styles available. You can also choose from an extensive range of sizes and glazing designs to complement the appearance of your property.
The cost of a new casement window will depend on the size, finish and style you require. However, we can tell you that prices start from £335 and go up to £600, meaning you should never have to pay too much for a high-performance solution.
If you’re not looking for a window that opens, a fixed casement window could be the answer. This type of window cannot be opened like a regular casement window and is solely used to allow more light into a room. A fixed casement window is also cheaper than an alternative version and will cost between £335 and £600.
In general, casement windows are very reasonably priced and range between £335 and £600. However, the size, finish and optional extras you choose will have an impact on the overall cost. Please feel free to check out our chart below for more information on casement window prices.

Casement windows are likely the most recognizable window style you can picture. They feature a frame, fitted with glass typically, and open outward on hinges, swinging from one side. However, there are more casement window types than you might expect.
Curious about how they differ and what their pros and cons are? Let’s dive right in!
Casement windows are the windows with hinges on one side and they open from the other side—like a door. Typically, they have a vertical configuration and open outward. However, this can be customized to suit architectural styles, like awning-style casement windows.
Casement windows generally come with either a crank—a lever mechanism at the bottom—or a simple handle for pushing them open.
Here’s a quick visual that explains the key components of a casement window:
Let’s explore the most popular casement window types or configurations, and what makes each unique.
These are the simplest casement windows, featuring just one panel or sash, typically installed with glass. They’re smaller than standard windows and are perfect for compact spaces like bathrooms or kitchens.
With a good insulation seal, single-panel casement windows provide excellent ventilation, natural light, and energy efficiency—a win-win for any small space.

French casement windows have two panels or sashes hinged to outer borders so they open in the middle. When fully opened, these windows provide the most unobstructed view and ample ventilation.
If you get cool breezy summers and love enjoying them inside, these double-panel casement windows are the best choice for your living rooms or bedrooms. Plus, even closed, they flood your space with natural light, adding warmth and charm to your home.

Traditional casement windows feature a crank at the bottom that you push and turn to open them. Push-out is the new version with no crack, you just unlock the window and simply push the sash outward. They often come with friction hinges or stays to hold the sash in place at your desired angle.
Push-out casement windows are more user-friendly and have a slightly more modern, minimalist aesthetic as desired for contemporary homes.

Imagine turning a typical vertical casement window into a horizontal one. With hinges at the top, these windows swing open from the bottom, creating an awning-like shape when open. Supporting stays allow you to adjust how far they open, making them versatile and easy to use.
This design makes awning casement windows especially practical in rainy places, as they can stay open without letting water in. They also pair beautifully with fixed windows to create versatile window combinations.

Swing casement windows have special hinges that let them open both inward and outward. This makes them highly customizable and practical for spaces where you want a seamless connection between indoors and outdoors, like patios or kitchen garden windows. When designed large enough, swing casement windows sometimes double as emergency exits.
If you’ve been considering casement windows for your home or office, here’s a quick guide to help you make the best choice.
Start by measuring your existing window width at three points—top, middle, and bottom—and use the smallest number to ensure accuracy. Do the same for measuring height. Then, measure diagonally from corner to corner to check squareness. If these diagonal measurements differ, your opening isn’t aligned. You’ll either need some adjustments or a custom size window.
Standard casement windows are available in 4-5 different materials pretty easily:
Small details like handles and finishes can elevate your windows from functional to fabulous. Cranks or push handles are common operational styles, so choose one that complements your decor.
For color, match or contrast the frame with your interior and exterior color schemes. You can also add grilles for a traditional look or opt for plain designs for a modern vibe.
Material costs play a big role in casement windows. Vinyl is the most affordable option, followed by composite, aluminum, and wood. Additional features like energy-efficient glass, custom finishes, or smart locks will further increase the cost but of course, you’ll also add to the value of your windows.
Plus, don’t forget professional installation costs to ensure proper fitting and long-term performance.
Casement windows are a classic favorite, whether for compact spaces like bathrooms or creating seamless indoor-outdoor connections in living rooms. They bring charm and style to complement any aesthetic.
