Popular Casement Windows

Casement windows are perhaps our most popular renovation option here at Castle. The term ‘casement window’ essentially covers any profile that opens outwards, meaning a broader array of windows fall under the ‘casement’ bracket than any other. We have dozens of different configurations options ranging from fixed frame models to wide seven or eight panelled pieces.

Our casement windows are available with both side and top hung panels, allowing homeowners to configure a window that will provide their home with ample ventilation and better yet, improved control over said ventilation. Our casement windows are so versatile that we even offer French and flush fitting variants of the conventional chamfered or sculptured frame.

As with all our uPVC windows, our casement frames are made bespoke to order. You’re promised a tailored build when you choose Castle Windows, enabling you to configure and design a set of casement windows that are perfect for your Newbury or Berkshire home. We have customisation options that allow these frames to suit both modern and traditional properties alike.

We offer the complete range of colour foils, including more striking colours as well as authentic woodgrains. You can complete your design with our wide range of accessories that will allow your windows to unify with the rest of your home. You’ll enhance your house’s visual appeal throughout when you invest in our stunning casement windows.

Thermally Efficient

Our modern casement windows are designed to provide your home with a reliable, year round thermal performance. A multi chambered profile works to prevent the ingress of cold air, while double glazing keeps a vacuumed pocket between your home and the chilly winter weather.

With this, the energy efficiency of your home improves over time, with the casement windows allowing your home to sit at the optimal temperature. You could even see your monthly utility bills become cheaper thanks to the enhanced thermal retention.


We fit each of our casement windows with industry leading Q-Lon weatherseals are standard. Renowned for their unrivalled, consistent performance levels, they ensure that your home is fully protected against adverse weather.

With this, you’ll never have to worry about issues including mould, rotting or the forming of damp spots. What’s more, modern trickle vents ensure that all rainwater is filtered away from the profile, preventing misted glazing or any warping of the uPVC profile.

Strong & Secure

Our casement windows come with Espagnolette locking systems as standard. These metal locks are incredibly robust and durable, as well as multipoint in design. They’ll prove incredibly difficult to damage, allowing you to feel safe in your home.

These locking systems work in tandem with galvanised steel reinforcement, dog bolts and steel hinges to ensure that these windows offer the complete home security performance. They will protect your family now and for the years to come.
