What are Bifold Doors?
Bifold doors are large fully glazed panels that fold together and slide to one side of the opening. Easy to open and close, bifold doors are also known as concertina doors or accordion doors.
Versatile Choice
Bifold doors are perfect for bringing the outdoors in, whether placed on the main house or on a conservatory.
Multiple Configurations
You can have as many as seven panels or as few as two, with a primary door at the side of your choice.
Light and Bright
External bifold doors often cover the majority of a wall, so that even when they’re closed your room is flooded with light.

Bifold doors have panels that fold and slide to one side of the opening. Easy to open and close, bi fold doors are also known as concertina doors or accordion doors. Add to the outside of your home or as an inside door between your Anglian conservatory and living space. Like French doors or sliding patio doors, external bifold doors are also a good choice for terraces or balconies.
Why Choose Bifold Doors?
-
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.
-
The 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.
-

Explore Bi Folding Door Designs
There are many ways to customise these concertina doors. You can decide how many panels you want, which way it opens (left or right), and if you want a primary door. You can also choose if it opens towards your home or your patio.
Even Number of Bifold Panels
Bifold doors with two, four, or six panels offers symmetry. Six panels that split in the middle and fold away at both ends is a popular choice over sliding patio doors. If there are four panels, you can add a primary door at one end and fold the other panels to the other end.
Odd Number of Bifold Panels
A design with three, five, or seven glass panels, one of the bifold doors acts as a traffic door. In some cases it is a good idea to include a primary door to gain easy access without opening the full door.

About our Bifold Doors
Secure
Our bifold doors have locks at different points along the sliding track. The primary door includes a 3-star cylinder lock. The glass is secure thanks to strong hinges, reinforced glass, and glazing beads on the inside. Our bifold doors also have child safety systems to prevent finger injuries.
Thermally Efficient
Well-fitted bi fold doors work as well as other doors to keep the cold out and the heat in. A thermal break in the frame helps insulate from the cold and the large panes of glass let the sun's heat warm your home. The insultation in our aluminium bifold door frames improves their energy efficiency.

Your Questions Answered by Us
Bifold doors include several glass panels known as leaves that slide on a track. The panels fold in a concertina and slide along the doorframe until they stack against the wall. Bifold doors have an even or odd number of panels and often include a primary door that opens in or out. This provides quick access without opening all the doors.
Bifold doors can be as secure as any other type of external door. To deter intruders, look for features like a multipoint locking system, high grade lock, robust hinges and toughened glass.
In most cases, you can replace an existing door with bifolds without planning permission. But you will need a structural engineer or surveyor to assess whether your home is suitable for installation. Our total price includes a survey to check this.
