What are Bi-fold Doors?

Bi-fold doors are typically a set of 2 or more standard size glass doors that open in a concertina style and neatly fold flat when open. Unlike a sliding patio door, that remains only half open, Bi-fold doors fully open to seamlessly connect your living space with your terrace, patio or garden.

Outside-in

Viewed from the inside, the flexibility of bi-fold doors is easily apparent. You have easy access to the outdoors, and can fold each section all the way back to allow in maximum light and air. Now the great outdoors really is just a step away, in this case allowing the family to dine al fresco without the need for taking everything outside.

Beautiful in any backdrop

This popular example shows how the same frame works equally well with brickwork rather than light stone, and also features black door handles. The doors are fully opened, neatly held in place by the magnetic contact pads, so there's no need for hooking back.

Magnetic, attractive and tough

From the inside, the views out even when the doors are closed are virtually unimpeded, allowing the light in, but not the cold. These doors are also super tough – able to withstand even a 200lb wrecking ball.

FAQs

Choosing new bi folding doors can be a daunting task, so to help you here are some popular FAQs which you might find useful.

+
Do bi-fold doors open in or out?
Bi-fold doors are designed to open both in and out, depending on the needs of your property. Most homeowners choose to have doors engineered to open outwards firstly to ensure that furniture does not get in the way. Secondly, if it has been raining and the doors remain wet, water will not drip all over your home if they open outwards.
+
Do front doors need to be fire rated?
No, But they will need to be fire rated if they go between the property and a garage or on to a public area.
+
Do I need planning permission for bi-fold doors?
Bi-fold doors are covered under permitted development rights. That said, in some areas planning permission may be required (for example, conservation areas), so it is always advise to check with your local authority. As a rule, if you are altering a door opening or installing bi-fold doors, you will need to ensure the existing opening is capable of withstanding the extra weight and will require a building notice.
+
How secure are bi-fold doors?
The majority of bi-fold doors are designed with a multi-point locking system as well as a hidden inline tracking system. This should make it almost impossible for a burglar to lift the bi-fold doors out of their mechanism.
+
Are sliding doors cheaper than bi-fold?
Bi-fold doors are extremely popular to open the indoor space to the outside. Whereas, sliding doors are a great alternative if space within your property in your home is an issue. Generally, costs for Bi-fold doors is higher than for Patio doors.
