Casement Windows

Making The Right Choices

When building from scratch or when restoring a property, every part of the project needs to be thought through. Choosing the right windows is as much part of the process as is choosing roofing materials or the position of a staircase. It’s not quite so obvious if you’re thinking about replacing existing windows, and all too often the choice made is a simple like-for-like swap. Over the years, many historic properties have been ruined with window styles that were never part of their original form. Now, there’s no need to compromise. Traditional and minimalist properties can have windows that respect their unique character.

There is, however, more to choosing windows than appearance. The attractions of a special home soon fade when the reality of poor insulation and non-existent security are realised. Another summer holiday spent painting window frames to keep out the autumn rains? No thanks! With the benefits of modern materials and 21st-century glazing technologies, you don’t have to live like that.

Comfort matters. Security matters. Ease of maintenance matters. So does taking good care of the planet and the money in your wallet. That’s why the right choice is a high-performing, Vinyl casement.

Casement Windows
Casements are the most popular style of window in Europe

So what exactly is a flush casement?

A casement window is one where the opening pane is held on hinges within a frame. That’s all – nothing complicated about it. The design has been around for centuries. They are the most common style of window in the UK, where most of them open outwards. The ‘flush’ part of the description only means that the opening part of the window doesn’t project out from the frame, but lies flush with it.

Flush-type casements are found in some very early properties and the popularity of the style has persisted, right up to the Edwardian era and into modernist and contemporary properties. Over the years, they have been variously plain and simple, or ornamented with finishing trims and feature glazing. A flush casement really is a design classic. And now that they’re available with performance to match their good looks, they’re guaranteed to remain popular for a very long time.


With a simple window design, every proportion has to be just right. The window’s individual components, its sashes, mullions and transoms have to work together to form a perfect whole. The shape is chamfered on the outside to shed the rain – just like the timber originals – and indoors you can enjoy the decorative sculptured shape.


Traditional colours relied on natural pigments and minerals. They work well with stone, aged brick, flints and lime-based renders. That’s why our color palette contains a range of finishes specially chosen to suit heritage properties. Alongside those you’ll find finishes that replicate the shades and grain of timber. If you want a different finish for inside your home, that’s possible too.


Window fittings have changed over the years. Mass production has taken over from the skill and craftsmanship of the blacksmith. But for heritage-style windows, maintaining the appearance of traditional fixtures is a must. Even though our Flush Casements have their own friction hinges, we’ve still got the right type of ironmongery to finish the job.

Your Options

Flush Casements have been around for a long time. We’ve chosen a range of ironmongery, finishes, glazing and accessories which will allow you to recreate the perfect window with the right period details for your home.


The clean chamfered lines of our Casement are ideal for outside, and inside you can enjoy a more detailed finish with gently sculptured curves.


Color is really important. That’s why we offer such an extensive choice. Fashions have changed and for a truly authentic look, you may need something surprisingly dark to work with a timber framed house, or for a coastal property, something bright and fresh. You may need the look of natural oak, or for modern properties a deep, flat-textured grey. We can’t tell you what to choose, but we can offer all the choice you want, including some very smart dual-color options.


Our hardware includes peg stays and monkey-tail handles with a choice of traditional finishes. The more modern-looking components, friction hinges and locking mechanisms are all neatly tucked out of the way.

Georgian bars

Originally designed to hold individual small panes together, georgian bars have long been a feature of period window styles. Our georgian bars are affixed securely to the outer surface of the glass, indoors and out. You get the efficiency of a single glazing unit and the small-paned appearance that your home needs. We’ve even got different sizes of georgian bar to get the proportions exactly right for your home.


Some timber casements included weather bars. These were both decorative and functional helping to shed rainwater. Even though our frames don’t need the extra weatherproofing, our system includes weatherbars. Authenticity of appearance shouldn’t be compromised.


There are both practical and aesthetic considerations to make when choosing your glazing, but really when thinking about appearance, nothing is off limits. You can choose stained glass, leaded lights or etched panes. Of course, plain and simple works well, too!

Our Casement system is designed to work with 24mm / 1″ double glazing. Without getting too technical, the actual energy efficiency depends on the way that the glazing unit is constructed and on the overall glass to frame ratio. We’re happy to give more information when we know a bit more about your home and its window dimensions but, right now, we’ll just say that our Casement system has been designed to achieve fantastic levels of insulation.
