What are French windows?
French windows are a popular window style for homeowners looking to brighten a room through natural light. With a high glass-to-frame ratio, they’re made up of two double-paned units that are hinged on one side of the window frame. Hence, removing the need for a central post (mullion) between the units that you’d usually find in standard casement windows.
While French windows can be used on the interior, they’re also very popular as exterior windows. But be careful not to confuse it with standard patio doors, which usually slide or fold open. You’ll recognise French windows because the absence of a mullion means the windows can seamlessly open inwards, outwards, and sometimes both. This is called floating mullions because the mullion is attached to the frame.
Why are they called French windows?
Despite the name, the windows we call French windows today aren’t actually from France. French windows are often mistakenly thought to have originated during the Renaissance Era in France in the 16th century. But in reality, they originated from Italian architecture. And if you want to dig deeper into history, you could even say they came from Roman and Greek architecture.
And it’s probably not surprising to learn that this naming confusion comes as a result of war. More specifically the Italian Wars. At this time during Renaissance Italy, Palladian architecture was popular amongst Italian architects. This particular style took a lot of inspiration from classic elements from Greek and Roman architecture, such as columns, arches, and domes. And amongst these designs was the basis of the French window we know today.
After the conflict, French soldiers brought back spoils of war, which not only included a range of Italian artwork, but also inspiration from Italian architecture that was later applied by French architects. They added their spin to it by adding more window panes into the structure. And that’s the French window we know today.
French Doors and Windows
While we call them French windows, some are tall enough that the opening they create allows you to walk through them like a door. Hence, you might also hear them referred to as French doors or double French doors. While considerably larger than French windows, these doors are often used to connect indoor and outdoor spaces and provide ample light and ventilation.
They are made of either wood, aluminium or UPVC and can be designed to match the style and aesthetic of the home. Since their origins in Italian architecture, French windows and doors have become popular in the United Kingdom and are even a common feature in many homes around the world.
French doors: What is a French door?
In France, French windows are known as “portes-fenêtres”, which translates to “windowed doors” or “door-sized windows” As the name suggests, these windows can also be tall enough that they reach the floor and are able to be walked through, essentially functioning as a door.
So when it comes to French windows and French doors, there’s really not much difference besides the size and functionality. Granted, you can also expect there to be a different locking mechanism on each so that they’re secure.
Exterior French doors
In UK homes, it is possible to have external and internal French doors. In fact, it is now common to see French patio doors used as a replacement for sliding glass patio doors because they let in more sunlight and natural air.
If you’re worried about the security of external French doors, then you’ll be reassured to know that they can be as secure as any standard door if properly installed and secured. However, the unique design of French doors, which typically consists of multiple glass panels, can make them more vulnerable to forced entry than solid wood or metal doors.
If you want to increase your home’s security, it is important to use sturdy hinges, toughened safety glass, and strong locks, such as a multipoint locking system. You can also install security devices such as deadbolts or glass break sensors to enhance the overall security of the house.
Compare French Window Designs
Many homeowners have been turning to French windows because not only are they able to provide access to the outside, but they also provide a great unobstructed view that lets in more natural light than standard windows. With so many customisable options, it has been a popular choice for those looking for functionality without compromising aesthetics.
Nowadays, you have customisable options for not only the window frame material, but also sometimes the colour. With so many options, comparing all the different French window options can be difficult. In this section we’ll discuss all the options available when looking for a French window so that you’re able to easily compare them.
UPVC French doors and windows
uPVC (unplasticised polyvinyl chloride) windows are one of the most popular French door materials for both new builds, window replacements and replacement French doors. It’s known for its durability, low maintenance, and energy efficiency. All this at a more affordable price point than other common materials.

Casement French windows
French casement windows, as the name indicates, elegantly combines elements of both the popular casement windows and the aesthetically pleasing French windows. With this combination, you’re able to reap the benefits of both functionality and appearance.
This French windows design consists of two casement windows side by side that open from the centre. If they were traditional casement windows, each window would open outwards with their own separate opening divided by a vertical post in the middle. But unlike traditional casement windows the French casement window provides one large opening absent of any obstructing posts.
Modern French windows
Despite being around for a while, the design of French windows hasn’t changed much over the years. However, if you compare modern French windows to the traditional French windows, you’ll find that they are more narrow in design.
A key advantage to modern French windows is the wide range of options for customisation–which you can read more about in the next section. It makes them a perfect choice for homeowners who are looking for a classic look with a modern twist.
There are many ways to modernise French windows. One of the most common ways is through style. So you can consider using more modern materials, such as aluminium, for a sleeker look. You can also consider modernising your windows with technology by installing automatic roller blinds or curtains that can be controlled via a smartphone or remote control.
French Window colours
The colour of your window frames are an important part to choosing windows. The colour can enhance your home’s overall appearance and can help you better match your specific home’s style. The most common window colours are white and black. But nowadays, with so many options, you no longer need to stick with standard or dull colours.
When it comes to French window colours, your options really depend on what window frame material you choose. For instance, while aluminium windows tend to come as either grey french windows, black french windows, or white french windows. You’re also able to paint it to the colour of your choosing. Wood is similar in this regard because it’s able to be stained and painted.
While there are a wide range of colour options, there are some things to keep in mind before deciding on a colour. The first being colour coordination and sticking to a colour scheme. Homeowners can easily match the colour of French windows or doors to the interior.
With that being said, you also shouldn’t be afraid to mix and match colours. For example, you can choose a hue for the window frame and sash, while painting the trim the colour of other elements in your room.
The last consideration is to find colours that define your French door. This is especially if you want your French door to be the star of the room as people pass through to access the garden outside. You can accent your French door in many ways, but one of the easiest is by painting it a complementary colour to the trim.
