What’s the difference between casement windows and flush casement windows?

Casement windows are the most popular windows in the UK. Why? They’re effective, energy efficient and aesthetically pleasing. Plus, they look great on almost any style of home. Whether you have a traditional or contemporary property, you can’t go too far wrong with these versatile frames.

Of course, there is a world of fantastic window options, from Sash Windows and French Windows to Bay and Bow Windows and Tilt and Turn Windows. So you should still shop around before making your final decision.

Still, casement windows are versatile and affordable — a dream combination of qualities. They’ll provide you with unobstructed views from your home and even come in two subtly different designs — standard and flush.

In this article, we take a dive into the world of casement windows. We’ll discuss the advantages and disadvantages of this much-loved window style, so you can make the best decision for your property.

Let’s get into it…


What is a casement window?

First, let’s cover the basics.

The word ‘casement’ originally referred to the part of a window that opens. Today, it’s used to describe a particular style of window.

A casement window is a top or side hinged window (usually) made from a single pane of glass. They have a built-in sash (or sub-frame) for easy opening and tend to be smaller than the opening they’re built into. If you opt for modern aluminium frames (known for their strength), your casement windows will be able to have a slimmer frame. 

Also, some people confuse picture windows for casement windows, but they’re not the same! Picture windows don’t have a sash, can’t be opened and tend to be larger than casements.


What is a flush casement window?

As they are still casement windows, flush casements are practically identical to ordinary ones.

Still, there is one significant difference.

While typical casement windows are ‘lipped’ (a side-on view shows that the openable part of the window protrudes from the frame), flush casement windows are not  — they lie flat against the wall of your property.

This makes flush casements look sleek and elegant. They are a great way to bring some subtle sophistication to your modern or traditional property.

What are the advantages of casement windows?

One of the best things about casement windows is their low cost. In fact, they’re one of the most cost-effective window types that we manufacture. As they’re also durable and long-lasting, they provide excellent value of money over their long lifespan.

High-quality casements also have great insulative properties. If well-fitted, they’ll provide an airtight seal when closed, keeping your warm air inside. You’ll benefit from all the advantages of modern double glazed windows, like reduced energy bills, no draughts, and improved soundproofing.

Finally, many people love their casement windows because of their simplicity. Their classic design makes them an incredibly versatile window option, and a great go-to choice for those struggling to decide on the best frames for their home. 

If your home has stand-out features, then your casements can let them shine while they provide a well-kept backdrop. On the other hand, if you want to have statement casement windows, this can be done with coloured or woodgrain finishes.


What are the disadvantages of casement windows?

While there are a few drawbacks to casement windows, these are very minor and shouldn’t impact their suitability for your home.

As casement ‘lips’ protrude away from your home, they are more exposed to wear and tear than other parts of the window. Over time, this might lead to an altered appearance. This being said, whichever type of window you choose, old frames will inevitably look more worn than new ones. 

Also, if you purchase your casements from a reliable manufacturer, like us, they will be weather-proofed and custom built to stand the test of time. Remember, choosing well-made windows is always more important than going for a particular style.

It might also be the case that other window designs look better on your property than casements, but this will mainly be down to your personal preference.


Heritage properties

There is one important thing to keep in mind. If you live in a conservation area or have a heritage property, then you’ll want to double check that casements are suitable window replacements for your home. 

There might be some restrictions as to what kind of windows you can install. If in doubt, contact your local authority. You might not be able to significantly change the appearance of your property.

If you are facing restrictions, the likelihood is that modern uPVC casement windows won’t be suitable for your home. If this is the case, don’t worry! We’ve fitted windows in countless heritage homes, so we’d be happy to offer our advice. We can advise on whether flush casement windows or our heritage windows are the best bet for your home.


Why choose flush casement windows?

Again, we should clarify that there really isn’t much difference between flush casement windows and lipped casement windows. Both types are durable, insulative, and versatile. Opt for casements and you’ll have a reliable, long-lasting window that will give you clear views of the outdoors. Plus, you’ll be able to create your desired aesthetic by choosing from a wide range of coloured and woodgrain finishes.

Flush casements do have two main benefits — they are usually suitable for heritage properties and they have a sleeker appearance. But it’s up to you to decide whether these factors are relevant or important to you.
