What Are French Windows and Doors? A Complete Guide for Homeowners

French windows and doors are a popular choice for anything from period properties to modern extensions. This is because they bring symmetry, light and a strong connection to the outdoors, all while giving everyday access and security.

In this guide, we’ll explain what French windows and doors are. We’ll also look at how they work and compare them against other types of windows and doors. Then, we’ll see which types of homes they suit best, helping you make the best choice for your property.

What Is a French Window?

A French window is made up of two side-hinged windows that open from the centre. Importantly, there is no fixed central bar between the two panes. When both sides are open, you get a completely clear, unobstructed opening.

In this way, French windows are basically double casement windows that meet in the middle and open fully. They’re often larger than standard windows and sometimes extend closer to floor level. 

What Are French Doors?

Meanwhile, French doors follow the same design principle as French windows, but in a door format. As such, they consist of two door panels that open from the centre.

French doors are a great option if you want to build easy access to gardens, patios or larger balconies. And because both panels can open, they create a nice, wide access point between inside and outside.

How Do French Windows And Doors Work?

French windows and doors look great and are highly practical – but they’re also simple to use. Each panel is hinged on the outer frame with one acting as the main opening leaf. This is the one you’ll use most often.

Then, there will be a second panel secured with flush bolts at the top and bottom. You can release it when you want to open both sides. When both panels are open, you’ll have a nice, wide opening leading to your property’s exterior. Many modern systems also include multi-point locking which secures both panels when closed, improving your home security.

What Do French Windows And Doors Look Like?

French windows and doors are symmetrical in design. They can be full-height or window-height, depending on the application, with a clean and classic look that’s easy to integrate into different property styles.

If you choose aluminium doors and windows, you get slimmer sightlines and larger glass areas. This helps bring in more natural light while keeping the design refined.

French Windows vs Casement Windows

If you’re currently looking at different window styles, you’ll probably compare French windows with casement windows. There are a few major differences:

  • French windows open from the centre with two panels while casement windows usually have a single opening sash
  • French windows have no central mullion, or bar, when they’re open, whereas casement windows usually have a fixed centre
  • French windows give you a full-width opening while casement windows provide more limited airflow
  • French windows have a symmetrical and classical look. Casement windows are simpler designs.

For a wider opening and a more balanced appearance, French windows can be the better option. Casement is a good choice if you want to keep things simple.

French Doors vs Sliding And Bifold Doors

French doors sit somewhere between sliding doors and bifold doors in terms of design and function. Here are some important differences and considerations: 

  • French doors and bifold doors both open fully but need space for the panels
  • Sliding doors save space but only partially open, not allowing as much access as French doors
  • French doors are simple and more traditional in design
  • Bifold doors suit very wide openings and modern layouts.

In this way, French doors are a good middle ground between sliding and bifold. You get a wider opening than sliding doors, without any overly complex systems. On top of this, you also get excellent access, added ventilation, increased natural light and an elegant appearance.

Why Aluminium French Windows And Doors Are A Modern Upgrade

As French windows and doors often provide larger openings, it’s important to use strong and sturdy material for the frames.

The excellent strength to weight ratio of aluminium allows for such slimmer frames. This increases the amount of visible glass for maximum daylight, without requiring any bulky frames.

For you as the homeowners, maintenance is minimal as aluminium resists rotting and fading. Modern systems also include thermally efficient profiles and secure locking options for the best possible performance.

Where Are French Windows And Doors Best Used?

French windows and doors are versatile and you can use them in many areas of the home. But in particular, they work best in these use cases:

  • To give simple rear garden access from the main home
  • To allow access onto balconies and terraces
  • To open up large kitchen and dining extensions
  • To maintain an elegant look during period property renovations
  • To bring symmetry and clean lines to modern homes 
  • Where a flexible option is needed for both smaller and larger openings.

If any of these apply to your home design ambitions, French windows and doors may be a good choice.

Are French Windows And Doors Right For Your Home?

As we’ve seen, French windows and doors suit a wide range of projects. They’re a good option to provide a fully openable space but without needing any complex mechanisms.

They also work well if you want a traditional or symmetrical design. Overall, their main strength is that they offer a balance between practicality and visual appeal – looking good while also staying secure and providing access where needed.
