Casement Windows

Elegant, Timeless, & Versatile Casement Windows

Casement windows’ style and versatility makes them the most popular choice when fitting new windows. They can be designed to suit any home in a range of materials, plus they are secure, thermally efficient and low maintenance. Casement windows provide clear, unobstructed views when open or closed, allowing maximum light into the room. The design of casement windows also allows for flexible ventilation options – angle them slightly to catch the breeze and move air about your house, or open them all the way out for full ventilation. We are so confident in the quality and security of our products, that all our windows come with a 10 year guarantee and are fully accredited.

We offer a bespoke service to tailor each window installation to your custom specific needs, requirements and budget.

The Benefits Of Casement Windows

High Energy Performance & Thermal Efficiency

Helping retain heat in your home and reducing costs is a must. Casement windows help seal out the cold for energy efficiency (you can also opt for internal blinds to help with blocking out that summer heat!). We offer acoustic laminated glass that improves sound insulation and can help with reducing outside noise. This contributes to them being one of the most popular window style solutions for houses of any size, in any location.

Open View & Ventilation

Make the most of your home’s natural light with a window that allows maximum sunlight and provides an unobstructed view outside. Alternatively, choose from the range of casement style designs below should you opt for small fanlight windows to open at the top for ventilation but not wanting to open the bigger window or you can request trickle vents which can help with minimising condensation. These are best to have in bedrooms, bathrooms and kitchens where condensation is more likely to occur.

Low Maintenance

Whether uPVC or Aluminium casement windows, they will never require heavy amounts of cleaning, just a simple wipe for dust or any dirt. And they have a long lifespan of roughly 30 years ensuring your money’s worth of investment.

Enhanced Security

Feel safe in your home, no matter what. Casement windows are secured by design, with multi point locking, double or triple glazing and toughened glass making them very secure window solutions. We also offer child safety restrictors for bedroom windows to keep your family safe and a minimum opening width. You may also wish to add secondary glazing, which can enhance security, warmth and noise insulation, particularly on properties which have existing period windows.

Variety of Styles

Casement windows are hinged at the side or the top in a range of styles and glazing options with toughened glass delivering the solution to any property from period to contemporary. Also incorporate either double or triple glazed units.

Casement Window Styles


Select your finish and hardware choice from a range of beautifully crafted, secure shoot bolt locking handles to match your frame. We have a wide range of casement window styles at our Fetcham showroom should you want to come visit for a browse and help make that all important final decision. These are just a few of the popular style variations available. If you can’t see the casement window style you are looking for, contact us for further options. In addition to regular styles, we can offer a flush casement, where the sash sits flush with the frame when the window is closed, creating a smooth, flat surface on the outside and additional protection from bad British weather. For elegant bars on your casement windows we also offer Georgian Bars, which sit internally within the glass, and Astragal Bars which sit external to the glass. You can also opt for decorative leads or glazing in fanlights, talk to our team to find out more.

Aluminium Casement Windows

Aluminium Casement Windows


Aluminium is a reliable choice as the strong, durable material is virtually maintenance free due to its corrosion and resistant strength. Your aluminium casement window will never rust, rot, peel, flake or warp. Aluminium casement windows are a thinner profile compared to other framing materials such as UPVC or timber, which results in a higher ratio of glass, which makes for a more modern look.

uPVC Casement Windows


uPVC, or Unplasticised Polyvinyl Chloride, is a highly durable, low-maintenance building material commonly used to frame double and triple glazed windows. uPVC casement windows have very low thermal conductivity, meaning like wood it naturally insulates, helping to keep heat in, cold and noise out, and to ensure that your home stays secure. Also known as PVC and PVCu, uPVC is a cost effective alternative to wooden or aluminium window framing. Take a look at our gallery of Casement Window Inspiration to see examples of uPVC casement windows we have fitted, and decide whether they are just what you’re looking for in your home.

Wood/Timber Casement Windows


Timber is a natural insulator which makes wood casement windows one of the most energy efficient choices as it reduces heat and cold transfer, as well as noise. Timber framing on your windows is also an excellent choice if you are looking for a beautiful timeless window that will be able to blend into an older property or meet the requirements of the planning/conservation officer. They are a traditional choice of window frame that can be painted to any RAL number colour, so you can customise your windows to the exact shade you wish, or match them to your front door.
