What are bi fold doors?

Bi fold doors can be also called concertina doors or folding doors. These doors have several panels that fold together and slide off to the side, offering an unobstructed clear opening into your garden. They typically have a traffic door that allows easy access to the outside without opening the whole section.

The beautiful panoramic views you will achieve with these doors are unrivaled by any other type of door. They offer an impressive yet effortless way to open up your home and simply let the outside in while keeping the weather out. Aluminium slim frames give more glass and more natural light. The hardware is subtle in appearance so only the hinge knuckles and handles show.

We work with a global leader in design and engineering of aluminium windows and doors, ALuK, who supply our aluminium profiles. Secure and robust, ALuK systems have been designed to meet and exceed requirements, while a complete range of accessories, design options and configurations offers unrivaled flexibility in terms of aesthetics and functionality.

What are the benefits of bi fold doors?

Customers typically choose to have folding doors installed due to their aesthetic appeal and the extra light these doors let inside. These doors provide a stunning transition between the indoors and outdoors while adding an impressive feature to your home. They completely transform the room and make it appear much larger, lighter and airier.

Unlike patio doors or sliding doors, bi fold doors open all the way and therefore allow you to maximise your living space. Elegant and contemporary, they will instantly transform the feel of your house, while providing superior security, safety, and energy efficiency.

Bi fold doors can be installed inside or outside your home, as an entrance to your garden or your conservatory. They can also provide a great way to split a larger room without losing out on space.

What options are available to me?

Bi fold doors have various opening configurations. For example, you can have the traffic door at one end or in the middle. Some customers choose to have a double door in the middle. Your traffic doors can open inside or out, to suit the layout of your living space.

You can order your doors in any RAL colour so it complements the style of your property and the colour of your window or conservatory frames. We can provide your door in single colours (both sides the same colour) or in dual colours (different internal and external colours).

Will bi fold doors add value to my property?

Whether or not will bi fold doors add value to your home depends on various factors. A concertina door certainly adds appeal and will modernise your home. According to recent surveys, installing these doors is likely to increase the value of your home. This, of course, depends on many factors, including the location of your property.

How secure are bi fold doors?

Customers are naturally concerned about the security of any external doors. The security of this type of door is typically very high. How high depends on the manufacturing and installation process.
