What are Bifold Doors?
Bifold doors consist of multiple glazed panels that slide and fold neatly to one side, creating a wide, open space between your home and the outdoors. Smooth, easy to operate, and beautifully engineered, they are also commonly referred to as concertina or accordion doors. Most commonly installed as external doors, bifolds allow you to fully open up your home to the garden, patio, or terrace — creating a seamless transition between indoor and outdoor living. They are also an excellent option for internal use, such as dividing a conservatory from your main living area, while still allowing natural light to flow through your home.

Even Number of Bifold Panels
Choosing an even number of bifold door panels — such as 2, 4, or 6 — creates a clean, symmetrical look. A six-panel design that splits in the middle and folds back at both ends is a popular option, especially for homeowners who want a wider opening than a traditional sliding patio door.
With a four-panel configuration, you can also include a main access door at one end for everyday use, while the remaining panels fold neatly to the other side when you want to fully open up the space.
Odd Number of Bifold Panels
Choosing an odd number of bifold door panels — such as 3, 5, or 7 — is a great option when you want flexibility without losing the modern bifold look. In these configurations, one of the panels is often designed as a traffic door, meaning it can be used as a main access door for everyday use.
This makes odd-panel layouts ideal if you want to step outside quickly, let the dog out, or bring in fresh air — without needing to fold back the full set of doors. When you do want to open up the entire space.
How Do Bifold Doors Work?
Bifold doors are made up of multiple glazed panels, often referred to as “leaves”, which operate on a smooth-running track system. When opened, the panels slide effortlessly along the track and fold neatly together in a concertina style, stacking to one or both sides of the opening.
Depending on your chosen configuration, the stacked panels can sit internally or externally, helping to maximise usable space inside your home while maintaining a clean, streamlined appearance.
Bifold doors can be customised with either an even or odd number of panels to suit the width of your opening. Many designs also include a convenient primary traffic door, which can open inwards or outwards for easy everyday access — meaning you don’t need to fully fold back the entire door set each time.
Enjoy the Warm Days
Open your bifold doors on warm days from Springtime onwards. Bifold doors are great for patios or decks. They make your home feel connected to the outside.
Light and Solar Gain
The light that bifold doors add to any home often makes them a desirable feature. But what is often overlooked is the warmth from the glazing throughout the winter months. Aluminium bifold doors reduce the flow of thermal energy through the frame to keep more heat in.
Doors Stack Away
Bifold doors are compact and take up little room when folded back. During barbecues or garden parties, you can enjoy having a wider opening than a regular door. This creates more space for your guests.
Aluminium is Best
External bifold doors made from aluminium need very little maintenance. Unlike timber and uPVC, it won’t warp due to the weather and is powder coated to last decades. Thanks to its strength, the frames can be thin to provide an unspoilt view of your outdoor space.
Multiple Layouts
Bifold doors are custom made and suitable for lots of different home types. Our smallest size is two panels and largest is seven panels. Our largest bi fold doors are up to 6200mm wide and 2400mm high.

Your Questions on Porches Answered by Us
Are bifold doors secure?
Bifold doors can be as secure as any other type of external door. Look for features like a multipoint locking system, high-grade locks, robust hinges and toughened glass to help deter intruders.
Do bifold doors add value to a house?
Yes, aluminium bifold doors can potentially increase the value of your home. They’re a highly desirable feature that not only look beautiful but also provide superior functionality by increasing natural light and creating a seamless connection to the garden. This can significantly enhance a property’s appeal.
Do bifold doors make a room cold?
Modern bifold doors use modern glazing and energy-efficient technology to minimise heat loss. Of course, if bifold doors are left open on a cool day, the room would cool down, just like with any open door.
How long do bifold doors last?
High-quality bifold doors can last a long time, usually up to 30 years or longer, depending on the materials and how well they’re maintained. Modern bifold doors are built for durability, offering long-lasting performance with minimal upkeep.
What is the best colour for bifold doors?
For a sleek, modern look, grey or black bifold doors work well and suit a wide range of property styles and interiors. If you want to make more of a statement, consider bolder colours. For a softer, natural look, greens or browns blend beautifully with outdoor spaces.
