A French door is one of the most popular ways to open a room onto the garden, and for good reason. They are elegant, they let in loads of light, and they suit almost any style of home. But how does a French door differ from a patio door or a bifold, and where does it work best? Here is a straightforward guide.
What are French doors?
French doors are a pair of glazed doors, hinged at the outer edges, that meet in the middle and open from the centre. Each door swings on its own hinges, and together they create a wide, clear opening when both are open. They are usually glazed from top to bottom to let in as much light as possible.
Unlike sliding doors, French doors swing open on hinges, so you need clear space for them to sweep into (or out of). Most open outwards in the UK to keep internal floor space free, though inward-opening versions exist.
They are a classic look that works on period terraces, modern semis and everything in between, which is why you see so many French doors on homes across York and North Yorkshire.
How French doors work
A pair of French doors has one leading door and one that stays shut most of the time. The second door is held closed by bolts (called shootbolts) top and bottom, and the leading door locks into it with a multipoint locking system. When you want the full width, you release the bolts on the second door and open both.
That gives you flexibility: nip in and out through one door day to day, then throw both open on a warm afternoon to connect the room to the garden.
French doors vs patio (sliding) doors
Both connect a room to outside, but they work differently:
- French doors swing open on hinges from the centre, giving a traditional look and a full opening, but they need clearance to swing.
- Patio (sliding) doors slide sideways on a track, so they take up no swing space and suit tighter spots. The trade-off is that one panel usually stays fixed, so you never get the whole width open.
If space to swing is tight, or you want an ultra-slim modern look with big panes of glass, sliding and patio door options are worth a look. If you love the symmetry and character of doors that open from the middle, French doors are the classic choice.
French doors vs bifold doors
Bifold doors are made of several panels that concertina and fold back against the wall, opening up a much wider span than a pair of French doors ever could. That makes them the go-to for large openings and a real indoor-outdoor feel.
The differences:
- Opening width. Bifolds can span a whole wall; French doors are usually a single pair.
- Look. French doors have a timeless, symmetrical charm; bifolds are sleek and contemporary.
- Cost. Bifolds generally cost more, as there are more panels, hinges and track.
For a smaller opening or a period property, French doors often look more in keeping. For a big kitchen extension where you want the wall to disappear, a bifold or slider may suit better. Our team fits aluminium bifold and sliding doors as well as French styles, so we can talk you through which fits your space.
What materials do French doors come in?
French doors are available in several materials, each with its own strengths:
- uPVC is warm, low maintenance and good value, and modern uPVC door ranges come in a wide choice of colours and woodgrain finishes.
- Aluminium gives slim frames and larger glass area for a crisp, modern look.
- Timber offers an authentic period feel but needs regular painting and care.
The right choice comes down to the style of your home, how much upkeep you want and your budget.
Where do French doors work best?
French doors suit a huge range of spots:
- Living rooms and dining rooms opening onto a patio or garden.
- Kitchens where you want light and easy access outside without a giant opening.
- Bedrooms leading to a balcony, or paired with a Juliet balcony on an upper floor.
They also work as an internal divider between two rooms, letting light flow through while still letting you close the space off when you want to.
What do French doors cost?
As a rough UK guide, a set of French doors, supplied and fitted, typically runs into the region of a few thousand pounds depending on material, size, glazing and hardware. Aluminium and timber usually sit above uPVC. Treat any figure you see online as a ballpark only, because the real price depends on your opening and choices. The best way to know is to have them measured and quoted. You can request a free quote and we will give you a clear, honest price.
Anything to do with structural openings, lintels or building work should follow current Building Regulations, so it is worth checking the latest rules with your local authority or letting your installer handle the technical side.
FAQs
What is the difference between French doors and patio doors?
French doors swing open on hinges from the centre, while patio doors slide sideways on a track. French doors give a full opening but need swing space; sliders save space but usually keep one panel fixed.
Do French doors open in or out?
Both are possible. In the UK most French doors open outwards to keep internal floor space clear, but inward-opening versions are available where that suits the room better.
Are French doors secure?
Modern French doors use multipoint locking, shootbolts on the second door and toughened or laminated glass options, so they can be very secure. The quality of the locks, glass and fitting is what makes the difference.
Are French doors more expensive than bifolds?
Usually the other way round. Bifolds tend to cost more because they have more panels, hinges and track. French doors are often the more affordable choice for a standard-sized opening.
Rounding up
French doors are a pair of glazed doors that open from the centre to connect a room with the outside, offering timeless looks and plenty of light. They differ from sliding patio doors, which glide sideways, and bifolds, which fold back to open a whole wall. Want to compare the styles and finishes?
