What are French doors?
French doors are one of the most common doors found in the UK. You’ll know if you have them as they’re more window-like than door — meaning the glass panes span the vertical length of the door.
They’re the perfect solution for those looking to balance style and functionality — offering a range of security options while maintaining visual appeal and letting natural light in.
Hard wood vs softwood French doors
Timber French doors are typically made using hardwoods or softwoods. Each wood has its own benefits unique to them.
Although there’s minimal visual difference, hardwood timber French doors are much more rigid, have an increased resistance to decay and don’t warp as much in response to rapid temperature changes.
However, softwoods are more malleable and workable than hardwoods. They’re much less rigid, they can be more easily carved and shaped to create more complex designs without affecting it’s structural integrity.
Some examples of timber used in our French doors are:
- Pinus Sylvestris (aka Redwood)
- Western Red
- Douglas Fir
Why you should upgrade French doors
For properties that have had French doors for a long time, it’s likely that they’ve sustained some wear and tear over the years.
Structural advancements in timber and glass mean that modern timber French doors are safer and more practical than ever before — and you could be missing out on the benefits of modernised doors.
Some of the reasons you should switch to French doors or upgrade your current ones are:
Energy efficiency – If your home still has its older French doors installed, it’s likely they’re single-glazed. Thicker, more durable timber lets joiners install double-glazing onto the door – giving your home a much-needed energy efficiency boost.
Improved security – Older French doors are susceptible to security problems. Because of the astragal locking mechanism that secures French doors being the only solution, it’s ability to repel thieves is extremely limited. Modern French doors come with additional security features and multi-point locking systems as standard that old, run down doors often don’t have.
Aesthetic appeal – Modern French doors look great, are extremely secure and last for a very long time. Timber French doors also have a unique styling, feel and build that can’t be replicated using UPVC plastics or aluminium. They’re also great for the inside of the home too — allowing natural light in to brighten up your space.
Customisability – Despite usually being one large pane spanning the length of the door, you can style your French doors exactly how you want them. Choosing between the number, type and arrangement of windowpanes, hardwood or softwood timber, and double or acoustic glazing means there’s an option for everyone – especially if you’re seeking an upgrade.
Easy to maintain – Provided you care for your doors, they can remain in good condition for decades. Timber French doors are inherently easier to fix and maintain sash windows are difficult to repair – it often involves replacing large sections of the unit rather than targeting specific areas.

What is the difference between a French door and a patio door?
Although they look similar in terms of the arrangement of the windowpanes, the main difference is how they’re fixed onto the building.
French doors are hinged to the side of the frame like a conventional door, whereas patio doors are on sliding tracks allowing a mobile panel to slide behind a fixed one.
Are sliding doors safer than French doors?
No, they’re not safer than French doors.
Because of the mechanism that allows the door to slide, locking options are typically limited to latches which can be easily broken by a thief that knows what they’re doing.
Can you sound proof French doors
Yes, you can soundproof French doors.
French doors can be fitted with acoustic glass to minimise noise coming into the home. This can also be double-glazed for further quieten loud noises.
Are French doors the same as double doors
All though they’re both extremely similar, the difference is in the design.
French doors are made from majority glass panelling to allow light in, whereas double doors are usually large, solid timber doors with small windows for light — often used for front doors.
Can I replace my French doors without replacing the frame
Provided the frame is in good condition and the door is the same size to fit the frame, it’s possible to install a door without ripping out the old frame.
Do you need planning permission to replace French doors
No, you don’t need planning permission to change a door. If you’re a homeowner, doors aren’t deemed a significant renovation and therefore don’t require planning permission.
However, if you’re renting or leasing a home, you will need to seek landlords’ permission before undertaking any renovations.
Can you replace the glass in French doors
Yes, the glass in French doors can be replaced.
The glass in a French door is held in place by small slats in the wood. This means broken windowpanes can be taken out and new glass can be slotted into position quickly and easily.
Do French doors increase home value?
A new set of timber French doors with modern locking mechanisms, made from quality materials and installed with care will almost certainly give your home a boost in value.
