Patio doors can transform the way a home connects with its garden or outdoor space. By introducing larger areas of glazing, they can bring in more natural light, improve views and create a stronger connection between indoor and outdoor living areas.
With several styles available, including French doors, sliding patio doors and bi-fold doors, choosing the right option depends on your property, available space, preferred appearance and how you intend to use the doors.
In this guide, we explore the main types of patio doors available in the UK, along with their advantages, potential drawbacks and the key factors to consider before making a decision.
What Are Patio Doors?
Patio doors are designed to provide convenient access between an internal living space and an outdoor area such as a garden, patio or terrace. They are typically available with large glazed panels, helping to maximise natural light and outdoor views.
Unlike conventional external doors, patio doors can create a much wider opening and make rooms feel more spacious and connected to the garden.
Modern patio doors are available in a range of materials, colours, configurations and glazing options, making it possible to find a design suited to both traditional and contemporary UK properties.
The Main Types of Patio Doors
There are three popular patio door styles to consider:
- French patio doors
- Sliding patio doors
- Bi-fold patio doors
Each style works differently and offers its own combination of aesthetics, practicality, ventilation, accessibility and available opening width.
Let’s look at each option in more detail.
French Patio Doors
French doors are a traditional and elegant option, particularly suited to smaller or standard-sized openings. They generally consist of two hinged door leaves that open from the centre.
Depending on the design, the doors can open inwards or outwards, while either one or both leaves can be opened when access is required.
French doors can also be customised with different glazing styles, including clear glass and decorative options such as Georgian bars, helping them complement both traditional and modern homes.
Advantages of French Patio Doors
- Classic and attractive appearance
- Good levels of natural light
- Can provide a wide opening when both doors are opened
- Suitable for a variety of property styles
- Flexible glazing and design options
- Useful where a traditional appearance is preferred
Potential Drawbacks
French doors require sufficient space for the door leaves to swing open. This means they may not be suitable where furniture, pathways or other features restrict the opening area.
They can also provide less uninterrupted glazing than large sliding or bi-fold systems, which may affect the size of the view available from inside the property.
Sliding Patio Doors
Sliding patio doors are a popular choice for homeowners looking to maximise glazing while making efficient use of available floor space.
Usually consisting of two or more panels, sliding doors operate horizontally along tracks, with one panel moving behind or alongside another.
Because the panels do not swing into the room or garden, sliding patio doors can be particularly useful where space is limited.
Why Choose Sliding Patio Doors?
One of the biggest benefits of sliding doors is their space-efficient operation. You don’t need to leave a large area clear in front of the doors for them to open.
They can also provide large areas of glazing, helping to maximise natural light and outdoor views.
Another advantage is flexibility. The doors can be opened partially for ventilation or further opened to create a larger access point between the home and garden.
Advantages of Sliding Patio Doors
- Space-saving operation
- Large areas of glazing
- Excellent outdoor views
- Good natural light
- Easy and smooth operation
- Suitable for contemporary properties
- Can be partially opened for ventilation
Potential Drawbacks
The available opening width depends on the configuration and size of the door system. Sliding doors also contain tracks that need to be kept clean and free from debris to ensure smooth operation.
Compared with French doors, there may also be fewer traditional design options, depending on the manufacturer and chosen system.
Bi-Fold Patio Doors
Bi-fold patio doors have become an increasingly popular option for UK homes, particularly where homeowners want to create a wide opening onto a garden, patio or terrace.
Rather than sliding or swinging open, bi-fold doors consist of several connected panels that fold and stack together to one or both sides of the opening.
When fully opened, they can create a substantial connection between the interior and exterior, making them particularly attractive for entertaining and summer living.
Benefits of Bi-Fold Patio Doors
Bi-fold doors can open across much of the available width, helping to create a more seamless transition between the home and garden.
They are particularly useful for properties where homeowners regularly entertain outdoors or want to make greater use of their garden during warmer months.
Many configurations can also incorporate a traffic door, allowing everyday access without having to fold back the entire set of panels.
Advantages of Bi-Fold Doors
- Creates a wide opening
- Strong connection between indoor and outdoor spaces
- Excellent access to gardens and patios
- Flexible panel configurations
- Modern appearance
- Suitable for entertaining
- Can maximise the usable opening width
Potential Drawbacks
Bi-fold doors can be more complex to manufacture and install than simpler door configurations. Their multiple panels can also interrupt the view more than a large expanse of fixed glazing when the doors are closed.
Other considerations can include maintenance, weather sealing, cost and privacy. Integrated blinds or suitable window treatments can help address privacy requirements where necessary.
Which Patio Door Material Should You Choose?
Patio doors are available in several materials, each offering different characteristics.
Common choices include:
Aluminium Patio Doors
Aluminium is a popular option for modern UK properties. It can provide strong, slim frames while allowing manufacturers to create large glazed areas.
It is often selected for contemporary homes where clean lines and large expanses of glass are important.
uPVC Patio Doors
uPVC patio doors are widely used because they can offer a practical, low-maintenance solution. They are available in a variety of colours and finishes and can suit many different property styles.
Timber Patio Doors
Timber can provide a warm, natural appearance and may be particularly appropriate for traditional properties or homeowners looking for a classic aesthetic.
However, timber generally requires more ongoing maintenance than uPVC or aluminium to keep it looking and performing well.
Composite and Hybrid Options
Some patio door systems combine different materials to bring together their respective characteristics. The most suitable option will depend on the property, budget, appearance and performance requirements.
How Often Will You Use Your Patio Doors?
Think about how the doors will function on a day-to-day basis before choosing a style.
If the doors will be used frequently as the main route between your home and garden, ease of access should be a priority.
French doors allow either one or both leaves to be opened, making them practical for everyday access. Sliding doors can also be opened quickly without requiring additional swing space.
Bi-fold doors can provide excellent access when fully opened, while a traffic door can make everyday entry and exit more convenient.
Are Your Patio Doors Mainly for Summer Use?
If your priority is creating a strong connection between your home and garden during the warmer months, bi-fold doors can provide a particularly wide opening.
When fully folded back, they can significantly reduce the physical barrier between an internal living area and the garden.
This can be useful when entertaining guests, hosting barbecues or simply enjoying more flexible indoor-outdoor living.
However, patio doors should also perform effectively when closed. Good-quality glazing, frames, seals and hardware are important considerations throughout the year.
How Secure Are Modern Patio Doors?
Security is an important consideration when choosing any external door.
Modern patio doors can incorporate a range of security features, including robust frames, multi-point locking systems and high-quality hardware. Some systems also include anti-lift or tamper-resistant features.
The exact security specification will vary between manufacturers and door systems, so it is worth checking the available security features before purchasing.
Glazing should also be considered. Depending on the system and specification, options such as toughened or laminated safety glass may provide additional protection.
Always choose patio doors from a reputable manufacturer and ensure they are professionally installed to the appropriate standards.
Which Patio Doors Offer the Best Views?
If maximising your view of the garden is one of your main priorities, sliding and bi-fold doors are worth considering.
Sliding doors can provide large expanses of uninterrupted glazing because their panels move behind one another rather than folding into multiple sections.
Bi-fold doors can create a very wide opening when fully open. However, when closed, the individual panels and frames can create more visible divisions across the glazed area.
The right choice therefore depends on whether your priority is the largest uninterrupted view when the doors are closed or the widest possible opening when they are fully open.
Which Patio Doors Are Easiest to Maintain?
Maintenance requirements vary according to the material and door system.
Generally, uPVC and aluminium patio doors are relatively straightforward to maintain, usually requiring routine cleaning and checks of the frames, glazing, hardware and tracks.
Timber doors may require additional care, including periodic treatment or refinishing to protect the material from weather exposure.
Regardless of the material, keeping tracks, drainage points, seals and moving components clean can help maintain reliable operation.
How Do You Choose the Right Patio Doors for Your Home?
There is no single patio door style that will suit every UK property. Your choice should be based on several practical and aesthetic factors.
Consider:
Available Space
French doors need room for their hinged leaves to open, while sliding doors operate within the footprint of the opening. Bi-fold doors require sufficient space for their panels to stack when opened.
Opening Size
The dimensions of the opening can influence which configurations are suitable. Wider openings may lend themselves to sliding or bi-fold systems, while French doors can work well for smaller openings.
Your Preferred Style
French doors can complement traditional properties, while aluminium sliding and bi-fold systems are often associated with contemporary architecture.
Natural Light and Views
If you want to maximise glazing, sliding and bi-fold systems can provide large glazed areas. Consider how the frames and panel configuration will affect the view when the doors are closed.
Security
Look for suitable locking systems, robust construction and appropriate safety glazing.
Maintenance
Consider how much ongoing maintenance you are prepared to carry out. Aluminium and uPVC can generally offer simpler upkeep than timber.
Budget
The cost of patio doors can vary significantly depending on their size, material, glazing, configuration, hardware and installation requirements. Obtain a detailed quotation so you can compare like-for-like specifications.
