What are Bi Fold Doors?

Bifold doors are a kind of folding exterior door made up of several panels that fold back against the wall in sections as a concertina. The framed glass panels slide along a track to make them easy to open and close.

With large panes of glass that let in plenty of natural light, exterior bifold doors are usually on the back of a house leading to a patio or garden. Like traditional French doors or sliding patio doors, bifold patio doors also fit upstairs openings, such as a terrace or balcony.

    Flexible, Concertina Doors

    Bifold doors offer a lot of flexibility when it comes to configurations. Choose the number of panels, the direction of opening and the inclusion of a primary door, known as a traffic door.

    Even Number of Bifold Panels

    Bifold doors with 2, 4 or 6 panels offer additional design flexibility. A 2-2 design with no primary door that folds away evenly at both ends is a popular alternative to sliding patio doors. You can also add a primary door that slides one way, and the remaining three doors fold away at the other end.

  • Anglian aluminium bi fold doors on an Orangery

    Odd Number of Bifold Panels

    Bifold doors fold away in pairs, so when you choose a door design with 3, 5 or 7 glass panels, one of the doors operates independently as a traffic door. It is a good idea to include a primary door to gain easy access without having to open the full set of doors.

Thermally Efficient

Well-fitted bifold doors are just as effective as other door types at keeping the cold out and heat in.

Our Happy Customers

Before
Mrs Baker, Norfolk

Aluminium Jet Black bifold doors

“Our new bifold doors are fantastic. We can now open the house up in summer. The house is warmer, more secure and they have added something special to our already characterful barn. Compared to our old timber doors, we are confident the new bifold sliding doors will reduce our heating bills. We wouldn’t hesitate to recommend Anglian and plan to use them again.”

Bi Fold Door FAQs

How do bifold doors work?

Bifold doors are made of several glass panels known as leaves that slide on a track. The panels fold in a concertina and slide smoothly along the doorframe until they stack against the wall.

How wide can bifold doors be?

Our bifold doors have a maximum width of 6200mm and a height of 2400mm with up to seven panels. Anglian bifold doors transform up to 90% of the entranceway into an opening, with the frame occupying just 10% of the space when stacked away to the side.

Are bifold doors secure?

Like all Anglian doors, exterior bifold doors offer an excellent level of security. They have a multipoint locking system fitted at several points along the sliding track, high-security hinges and toughened glass to deter intruders. The primary bifold door has a 3-star Yale lock and glass panels with glazing beads on the inside to prevent them from being removed from the outside.

How much do bifold doors cost?

Bifold doors may be more expensive than French or sliding patio doors in the same material but are worth every penny. A quote from us for exterior bifold doors includes the initial survey and measurements right through to aftercare. You’ll pay one price with no hidden costs.

Are bifold doors better than sliding doors?

While both slide along a track, Bifold doors and sliding doors open in different ways. Bifold doors have up to 7 panels that fold away at each end of the door frame, turning up to 90% of an entranceway into an opening. By contrast, sliding doors have up to 4 panels and slide one behind the other with a door fixed in place in the frame. The better option depends on what features are most important to you. Speak to our team today to talk through the pros and cons in more detail.
