External Bifold Doors for Modern Living
Bifold doors are a popular choice for homeowners who want to create a seamless connection between indoors and outdoors. With large glass panels and smooth folding operation, external bifold doors can transform kitchens, extensions, dining rooms, conservatories and garden rooms.
Unlike traditional french doors or sliding patio doors, bifold doors fold neatly to one side, helping you make the most of your opening and enjoy uninterrupted views.
Whether you want a compact bifold door set or a wide multi-panel folding door system, our range includes durable options to suit your home, budget and style.
Benefits of Bifold Doors
Bring in More Natural Light
External bifold doors use large glass panels to welcome more natural light into your home. This makes rooms feel brighter, larger and more inviting throughout the year.
Connect Indoor and Outdoor Space
Bifold patio doors create one flowing living space between your home and garden. They are ideal for entertaining, summer evenings and making better use of your outdoor space.
Save Space
Bi fold doors fold back on themselves, making them more space-efficient than many traditional external doors. This gives you greater flexibility when planning furniture, access and layout.
Improve Kerb Appeal and Property Value
Bifold doors add a premium finish to your home and can increase appeal to potential buyers. Their modern look, practical design and energy efficient performance make them a smart long-term investment.
Types of External Bifold Doors
Aluminium Bifold Doors
Aluminium bifold doors offer strength, slim sightlines and a contemporary appearance. They are lightweight, durable and ideal for larger openings where maximum glass area is important.
Many aluminium bifolds use thermally broken aluminium to improve insulation and reduce heat loss. This supports better thermal performance and helps keep heating bills under control.
Popular finishes include black, white and anthracite grey, making aluminium bifold doors a stylish option for modern homes.
uPVC Bifold Doors
uPVC bifold doors are a practical and cost-effective option for homeowners looking for energy efficiency and low maintenance. They are available in a range of colours and can provide a seamless flow between indoor and outdoor spaces.
Wooden Bifold Doors
Wooden doors offer a warm, traditional appearance and can work beautifully in period homes or country-style properties. They may require more maintenance than aluminium doors or uPVC options, but they provide natural character and strong visual appeal.
Bifold Patio Doors
Bifold patio doors are perfect for opening up kitchens, dining rooms and living areas. They combine the benefits of patio doors with the flexibility of a folding door system.
External bifold patio doors are especially popular for homes with garden access, allowing you to enjoy wide openings, improved natural light and easy movement between spaces.
Compared with sliding doors, bifold patio doors can open up almost the full width of the frame, creating a more open and spacious feel.
Security Features
Security is an important part of every external door. Our bifold doors are designed with strong frames, secure locks and dependable hardware.
- Multi point locking systems for improved protection
- Multi point locking across the door set
- Drop bolts for added stability
- Toughened safety glass for everyday safety
- Laminated glass options for enhanced security
- Robust bifold door hardware for smooth operation
Multi point locking systems help distribute locking points along the door height, making bifold doors more secure than basic single-lock systems.
Energy Efficiency and U Values
Modern bifold doors are designed to improve energy efficiency while still offering large areas of glass. Double glazing, quality seals and thermally broken aluminium all help reduce heat transfer.
A door’s thermal performance is often measured using a U value. The lower the U value, the better the insulation. Current building regulations require new external doors to meet strict energy performance standards.
Choosing energy efficient bifold doors can help reduce energy bills, improve comfort and make your home more suitable for year-round use.
Choosing the Right Bifold Door Set
When choosing external bifold doors, consider the size of your opening, the number of panels, your preferred material and how often you will use the doors.
Panel Configuration
Bifold doors are available in different panel layouts. A larger opening may need several panels, while a smaller space may only require a compact bifold door set.
Traffic Door
A traffic door is a single lead door within the bifold system that opens like a normal door. This is useful when you want quick access without folding back every panel.
Track Systems
Quality track systems are essential for smooth operation. Bifold doors usually use a main track and guide track, with some systems using an upper track for additional stability.
Colour and Finish
Our external bifold doors are available in popular colours including anthracite grey, black and white. Anthracite grey remains one of the most popular choices for modern aluminium bifolds.
Installation and Maintenance
Installing bifold doors correctly is essential for performance, security and long-term reliability. Poor installation can lead to gaps, sticking panels or reduced energy efficiency.
Professional installation helps ensure the frame, panels, seals and locks are fitted correctly. It also helps your new doors comply with current building regulations.
To maintain your bifold doors, clean the glass and frame regularly, remove debris from the track systems, lubricate moving parts where required and check the locks, hinges and drop bolts.
External Bifold Doors vs Sliding Patio Doors
Bifold doors and sliding patio doors both help connect your home with your garden, but they work differently.
Sliding doors move along a track and usually leave part of the opening covered. Bifold doors fold back in panels, allowing a much wider opening when fully open.
Sliding patio doors can be a good option where space is limited, while bifold doors are ideal if you want the widest possible access and a stronger indoor-outdoor connection.
External Bifold Doors vs French Doors
French doors are a traditional choice and work well for smaller openings. However, external bifold doors provide a wider opening and a more modern appearance.
If you want to maximise natural light and create a more open living space, bifold doors are often the better option.

Frequently Asked Questions
What is the new trend instead of bifold doors?
Sliding doors, especially large-format sliding patio doors, are a growing trend because they offer wide glass areas and slim frames. However, bifold doors remain popular because they create a wider opening when fully folded back.
Do I need planning permission for bifold doors in the UK?
In many cases, replacing existing patio doors with bifold doors does not require planning permission. However, you may need approval if you are creating a new opening, changing the structure, working on a listed building or living in a conservation area.
What is the disadvantage of folding doors?
The main disadvantage of folding doors is that they require accurate installation and regular track maintenance. Poorly fitted bifold doors can become difficult to open or may not seal properly.
How much does it cost to install a folding door?
The cost of installing bifold doors depends on the size, material, number of panels and installation requirements. As a guide, bifold door sets can range from around £1,759 to £5,799 depending on specification.
Are bifold doors energy efficient?
Yes, modern bifold doors can be energy efficient when they use double glazing, quality seals and thermally broken aluminium frames. Always check the U value when comparing products.
Are bifold doors secure?
Yes, quality bifold doors include multi point locking, toughened glass, strong frames and secure hardware. Laminated glass and upgraded locks can provide additional protection.
