What Are Bifold Doors?

Bifold doors (sometimes referred to as concertina doors or fold doors) are a series of connected glass panels that fold neatly to one side of the opening.

They slide and fold along a top track for easy operation, stacking tidily without intruding into your living space. You can choose from 2 to 7 panels, depending on the width of your opening — perfect for anything from a cosy kitchen to a grand garden room.

Benefits of Bifold Doors

A Seamless Connection with the Outdoors

External bifold doors blur the lines between inside and out, creating an airy, open-plan feel. Whether it’s a summer BBQ or a quiet coffee in the garden, they bring the outdoors in beautifully.

Maximise Natural Light

Because bifold doors are mostly made of large pieces of glass, they let in far more natural light than traditional French doors or patio doors. Rooms feel bigger, brighter, and more welcoming year-round.

Energy Efficiency You Can Trust

Our bifold door sets feature thermal breaks and Low-E glass, designed to cut down on heat loss without sacrificing style. With U-values as low as 1.1 W/m²K, you’ll notice a real difference in comfort — and heating bills.

Durability That Lasts

Crafted from superior quality aluminium, our bifold doors are lightweight, tough, and designed to withstand whatever the British weather throws at them. Thanks to powder-coated finishes, they’re low maintenance too.

Security You Can Rely On

We know peace of mind matters. That’s why our bifold doors feature multi-point locking systems that meet strict PAS 24 burglary standards.

FAQs

Are bifold doors better than sliding patio doors?

It depends on what you’re looking for. Bifold doors open up the full width of the space, creating a true indoor-outdoor feel. Sliding patio doors usually leave part of the opening closed.

How energy efficient are aluminium bifold doors?

Very. Thanks to modern thermal break technology and Low-E glass, aluminium bifold doors can achieve A+ energy ratings, helping to keep your home comfortable and your bills lower.

How do I maintain my bifold doors?

Our aluminium bifold doors are built for minimal maintenance. A quick clean of the tracks, hinges, and frames a few times a year is usually all it takes to keep them working like new.
