An Introduction to Casement Windows
When most people picture double glazing, it’s usually a classic white window. Clean, simple and seen on homes all across the UK. More often than not, what they’re thinking of is a casement window.
But take a closer look next time you’re walking down a residential street. You’ll see just how different every casement window actually is. Because the casement window is perhaps the most flexible and versatile window there is.
Here at Majestic Designs, we work with you to design casement windows that suit your home perfectly. Your windows are then made by our expert manufacturing team in our Cheddar factories before being fitted by our highly skilled window installers.
Here’s a closer look at what makes casement windows so versatile and how you can make them your own.
Designing Your Casement Windows
Casement windows are hinged at the side or the top and open outwards, offering excellent ventilation and clear sightlines. One of the first decisions to make is how you’d like your windows to open. You might choose:
- A simple side-hung design that opens like a door
- A top-hung style for smaller spaces like bathrooms
- A combination of fixed panes and openers for larger windows
Take a wide living room window, for example. You could divide it into three panes with opening sections on either side or go for an asymmetrical design with a single opener and a large fixed pane to maximise light. It’s completely up to you.
Our design team will work with you to choose the most practical layout for each room, whether that’s matching existing window styles, improving airflow or simply making everyday use easier.
Frame Colours and Finishes

White remains a timeless choice, but it’s far from your only option. We offer a full palette of coloured and woodgrain finishes to help your windows blend in (or stand out) depending on the character of your home.
Some of the most popular finishes include:
- Golden Oak, Rosewood and Mahogany – ideal for a more traditional or heritage-inspired look
- Irish Oak and Rustic Cherry – soft woodgrains that bring warmth to stone or rendered exteriors
- Chartwell Green – a classic country house shade that suits cottages and period homes
- Anthracite Grey – a modern, architectural finish that works well with crisp render or dark cladding
Coloured UPVC windows are just as low maintenance as the white versions and, unlike painted timber, the colour won’t peel, crack or need repainting.
Choosing the Right Glass
Glass might seem like the simplest part of the window, but there’s more choice here than you might expect. Alongside clear double glazing, we offer:
- Obscured or frosted glass, ideal for bathrooms, cloakrooms or hallway windows
- Decorative leaded glass, perfect for period properties or homeowners who want to retain a more traditional feel
- Toughened or laminated glass for added safety and peace of mind in specific locations
All our units are double glazed as standard and include warm-edge spacer bars and argon gas fill for thermal efficiency.
Energy Efficiency and Security of Casement Windows

Away from the appearance of your casement windows, it’s reassuring to know our windows achieve an A+14 WER (Window Energy Rating) as standard, which means they’re incredibly energy efficient.
Security is top-notch too. All of our casement windows are fitted with multi-point locking systems as standard and easily exceed BS7950 security specifications, so they more than meet legal requirements for window security. For those who want added reassurance, we also offer upgrades to Secured by Design, the UK Police initiative that focuses on crime prevention through design.
Casement Windows Are Anything But Standard

There’s a reason casement windows are seen in so many homes. They’re straightforward to use, look good from every angle and can be configured in more ways than most people realise. Whether you want a full set of new windows or are upgrading one room at a time, casement windows offer a classic base with endless custom options.
Our team at Majestic Designs is here to help guide you through the process. From your initial consultation to the final installation, everything is handled in-house by our friendly and experienced team, including manufacturing, surveying and fitting.
