What Are French Casement Windows?

You may already be very familiar with casement windows, but what about French style casement windows? 

French casement windows are made up of two windows that push out beyond the envelope of your home. Typically, they don’t have a vertical post in the middle and will open out from the centre. Unlike a traditional casement window, this allows for an unobstructed view when the windows are open.

Not all windows of this type are the same, but the most common is the push out French style casement window. Inswing French casement windows are also available.

When Should You Use French-Style Casement Windows?

French style casement windows are excellent when installing a window in a large, open space such as your kitchen or bedroom. They’re not so suited to hallways, stairwells, or toilets.

As they open fully, they can let in plenty of light and air. If you have a room that enjoys a fantastic view, when opened a French window will allow you to enjoy it without obstruction.

What Are the Features & Benefits of French Casement Windows?

So, why should you opt for a French casement window? The choice is completely yours but let’s lay out some of the benefits so you can decide whether French casement windows are the right choice for you. 

  • Ventilation – French windows open out to 90 degrees plus and allow for rapid air flow into the room. You also have the choice of opening just one side if you need some ventilation, but don’t want to open the windows the whole way. 
  • Security – French window security is typically of a very high standard. They come with locks that are highly secure so you don’t have to sacrifice on safety. They also open so wide that they can also double up as a fire escape if needed. 
  • ViewsAs mentioned previously, French windows give offer unobstructed views of the great outdoors. 
  • Low MaintenanceFrench windows, especially uPVC ones, are extremely low-maintenance. A quick wipe every now and then will keep them clean, and they don’t need to be treated regularly like wood.
  • EfficiencyFrench windows offer better energy efficiency than double hung windows, whilst simultaneously providing more ventilation. 
  • VarietyWith French style casement windows, there’s plenty of opportunities for customisation and personalisation. This makes them particularly appealing to our design-minded customers.

What Are Lipped and Flush Casement Windows?

The most popular variety of window in Britain is the casement window. Casement windows open outward on hinges, and offer several advantages when compared to sliding sash windows. Casement windows can, for example, incorporate compressible seals, which run around the edge of each panel and ensure that the window is appropriately air-tight when closed.

Casement windows come in two varieties: lipped and flush. If you’re in the market for a new window, it’s worth considering both of them. In this article, we’re going to take a look at the differences between lipped and flushed windows, to help you assess which will be the better match for your property.

What Are Lipped Casement Windows?

So called ‘lipped’ casement windows are the type most people think of when they hear the term ‘casement’ window. They stand slightly apart from the window, because they incorporate another layer of sealing.

This solved a problem affecting many early flush casement windows: leakage. The flushed windows of centuries gone by would lack this extra layer of sealing, so whenever it rained, moisture would find its way indoors. This would result in unpleasant consequences – most notably, damp.

When lipped casement windows were invented, they offered a solution to this problem. As such, you might hear of lipped casement windows described as ‘stormproof’ casement windows. The majority of lipped casement windows today are of the uPVC variety, but you can still get timber ones, too. Aluminium, being a naturally strong and thin material, isn’t so compatible with the chunky design of a lipped casement window.

What Are Flush Casement Windows?

Flush fit windows are those which sit level with the frame. They’ve been in widespread use since the 19th century, when all frames were made from timber. As such, a flush-fitting casement window often makes a great match for older properties that will benefit from a more traditional look. That said, a modern home might equally benefit from a flush window – particularly if you’re a fan of straight lines and symmetry.

Modern flush casements are just as effective as lipped casements at excluding draughts and moisture, as they incorporate the two layers of sealing into a smaller space. They’re also offered with all the glazing options and trickle vents you might expect from a modern window. As such, when deciding between the two, appearances should be your number one consideration.

Should You Choose Flush or Lipped Casement Windows?

Once upon a time, the two varieties of window differed noticeably in performance, but thanks to modern materials and engineering, this is no longer the case. Both flush and lipped casement windows provide ample weather-sealing and plenty of glazing, meaning your choice will mostly come down to personal preference. Take a look at both designs and see which one you like the look of best.

How to Repair a Casement Window

The most popular style of window in the UK is the casement window. Unlike its closest rival, the sash window, the casement window opens by swinging outwards on a set of hinges.

This offers several advantages.

For one, casement windows are less complex and easier to maintain than sash windows, and they can be equipped with compressible seals which keep out draughts and can help cut your energy bills.

However, as resilient as casement windows are, problems can occasionally occur. Thankfully, the majority of those problems can be solved without the need to call in a professional. In this article, we’ll look at how to repair casement windows. We’ll examine some common issues, and see how they should best be addressed.

How do you fix a sagging casement window?

Throughout a casement window’s lifespan, it will gradually sag as a result of gravity, and it only takes a few millimetres of drop for the window to begin catching against the frame. If your window is dragging, you need to adjust the hinge channel to compensate. This should be done from the outside. You’ll need to first establish the direction in which your window is sagging, and then move the corresponding hinge.

Step 1.

First, we’re going to remove the arms that make up the hinge at the bottom of the window. Open it and unscrew everything. You’ll then be able to lift out the sash which tethers it to the window frame.

Step 2.

It’s time to fill in the existing holes. Do this with epoxy resin if your windows are uPVC, or wood-filler if they’re timber. Don’t be tempted to skip this step, as you’ll be drilling new holes just a few millimetres from the old ones, and the drill could slip into the old holes. Be sure to rub the filling smooth for the best possible finish.

Step 3.

Now you’re going to drill some new holes using an 1/8” pilot drill. Drill them a couple of millimetres across from the old holes. A little bit of guesswork may be in order here, given that there’s no way to test the window before you’ve secured it to the frame. If you’ve only just noticed the problem, chances are that moving the hinge across a small increment will result in a significant improvement.

How do you clean casement window hinges?

On the other hand, rust accumulating on your gears can cause the window to become stiff and eventually inoperable. Cleaning the gears thoroughly requires a little bit of disassembly – but it’ll help fend off corrosion and keep your window working as it should for longer.

Step 1.

First, we’re going to unclip the operator arm. This usually comes apart from the window via a clip. It’s attached at the other end via a series of screws, which can be removed with the help of a trusty cross-head.

Step 2.

Next it’s time to clean away the grime. Do this over a plastic tub using methylated spirits and an old toothbrush. Scrub until every last bit of grime has been removed.

Step 3.

Before we return the gears to the window, we need to ensure that they’re lubricated and protected from the elements. Apply your lubricant generously and use a soft cloth to distribute it across the entirety of the metal. Work it into the gears by moving them back and forth. When they move easily, you’re ready to reinstall.

Step 4.

Some casement windows are attached to an arm which runs along a track at the bottom of the window. These should be cleaned using a harsh, wire brush and solvents applied to a cloth (which should lift up all of those stray metal particulates).

Make sure you’ve gotten right into the track, and apply a layer of lubricant when you’re done, as just described. Again, you can work the lubricant in by moving the window back and forth.

Now, there are some instances where it’s impossible to repair the hinge, and you’ll need to look at replacing the hinge instead. Replacement hinges for casement windows are widely available and inexpensive.

How do you re-seal a casement window?

The seal around the edge of your window contributes enormously to its energy efficiency. If yours is damaged, then fixing it should be a priority. The stripping might have been pulled away from the corner of the frame, in which case you can address the problem by simply sticking it back into place with a dab of polyurethane sealant. On the other hand, repeated cycles of compression and expansion can, over the years, cause the stripping to lose its elasticity. When this happens, it’s time to replace it.

Step 1.

Pull the strip loose from the window. Do this slowly to minimise the risk of the wedge section of the strip remaining stuck in the grove. Should this happen, you’ll need to work it loose using a coat hanger or hobby knife.

Step 2.

Insert your new weather-stripping, starting from the corners. You won’t need to apply any adhesive, here; it should slide into the groove with a reassuring ‘click’.

How do you replace a handle on a casement window?

When your handle is spinning, but the window isn’t opening, a broken shaft is normally to blame. In most cases, this problem can be fixed with a replacement handle. You can buy replacement cranks which can be adjusted to fit different spindles, or you can contact the manufacturer and ask for a like-for-like replacement. If it’s the shaft itself that’s worn down, you can often correct the problem temporarily by filing the edge of the shaft so that the screw can lock properly. Don’t expect this fix to hold up for long if you’re opening and closing the window repeatedly, however.

Anything else?

Casement windows are incredibly robust and given the right care and attention, they’ll last for years. To stand the best possible chance of avoiding problems, we’d suggest taking a pro-active approach. Check your windows periodically for damage and if you notice a problem, don’t be tempted to delay in fixing it. The chances are that it’ll only get trickier (and more expensive) to solve!

Casement vs. Sash Windows

The right window makes an enormous difference to both the look of a property and the way that it functions.  If you’re shopping for a window, then you’ll be face with two main categories to choose from.  These are casement windows and sash windows.  Each has their relative strengths, which you’ll want to consider before making a commitment to one or the other (especially since, for the sake of consistency, it’s generally advisable to use the same sort of window throughout your home).

While personal taste will obviously impact your decision, it’s also important to consider the functional differences between the two sorts of window.  This article will explain those differences, to help you come to a decision that’ll suit your home.

What is the difference?

Before we get started with comparisons, let’s first establish what it is that we’re talking about.  Exactly what is the difference between a sash window and a casement window?

Casement windows

Casement windows are the most common type of window in Europe.  They come equipped with hinges which allow them to swing open.  Generally, they come in pairs which open away from one another, like a set of double-doors.

Casement windows also feature a crank which doubles as a window lock.  This might look just the same as a handle – but it’ll also ensure that the window is locked in place while it’s open.  This will prevent the wind from moving the window around and causing problems.

Sash windows

Sash windows came into prominence in the Georgian era (though they were first introduced much earlier), and they remained popular well into Victorian times.  Sash windows consist of one or more panels, or sashes, which slide atop one another to create openings.  Most commonly, these panels move vertically – but you can get horizontally-opening sash windows, too.  Vertically-opening sash windows are assisted by balancing weights, pulleys and springs, which are hidden within the window frame and assist with opening the window. They also allow the sash to stay in position once the window is opened.

There are two varieties of sash window to choose from – those which feature two mobile sashes, or ‘double-hung’ windows; and those which feature just one mobile sash and a fixed one, usually at the top of the window.  The former style is more common nowadays, and allow for greater flexibility for a marginally-increased cost.

Which one is best for my home?

In order to choose between them, you’ll need to assess the merits of each.  Let’s run through a few of the most important ones.

What are the advantages of a casement window?

  1. Casement windows tend to be very energy efficient, as they come with a tight seal around the edges which will compress when the window is closed. When it comes to draught-excluding prowess, then, they’re second only to fixed windows (those which don’t open at all).  Are casement windows more energy efficient than sash windows, though?  The answer varies according to the design; the truth is that modern sash windows provide strong competition, as they come equipped with substantial seals of their own.
  2. Casement windows offer a contemporary look, and form a great match with more modern homes. They’re available in a range of materials, and thus choosing one is simply a matter of choosing the right material and style.
  3. Since the lock is embedded into the frame of a casement window, they’re also a great deal more difficult to break into. A would-be intruder will need to break into the casing itself – and simply prying it open using brute force won’t be an option.
  4. You’ll also find that taller casement windows are easy to open and close, as you won’t need to reach upward to fully extend them as you might a sash window. If you’re a little on the short side, this might tip the balance in favour of a casement window.
  5. Finally, one of the biggest advantages of a casement window is that it’ll provide larger glass panels. This will provide an unobstructed view outside, whilst letting the maximum amount of light into your home.

What are the advantages of a sash window?

  1. Sash windows are easier to open if there is an obstruction in front of the window. If you’re shopping for your kitchen, for example, and have to reach all the way over the sink in order to fully open the window, then sash windows might provide a better alternative.
  2. Sash windows are simpler in design than casement windows. With fewer moving parts to malfunction, their failure rate tends to be a little lower.  Moreover, when problems do occur, they’re usually simple to fix – a common one being a ‘dropped window’ where the sashes aren’t being held up correctly by the balancing weights built into the jambs.
  3. Sash windows offer a traditional style that’s a fantastic match for period properties. If you’re the owner of a Georgian or Victorian home, then you’ll probably find that no other style of window looks quite as good as a sash window.
  4. Sash windows also don’t require any space outside the window to open. If your home is built right up against another wall, then sash windows might well be your only option.  The same is true if there’s a tree growing nearby – since sash windows don’t open outward, there’s little chance that you’ll inadvertently open it into an obstacle.

So what should you choose – a sash window or a casement window?

As we’ve seen, both technologies offer distinct plus points.  Your choice will therefore depend on your circumstances and personal preference – and there are no real right answers!  Whichever style you choose, you’ll want to be sure you’re sourcing your windows from a reputable supplier.  Suffice to say, we here at Windows and More have the items you need, along with the expertise required to get the best from them.
