What is the maximum number of bi-fold sections?

We can fit bi fold doors into any entrance up to 6.4metres wide. This will be done with up to a maximum of 7 separate door sections.

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 as it provides more space in the room for furniture. But we can work with the home owner to define which doors open and the direction of sliding.

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 which Everest can help advise on. 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 may require a building notice.

How secure are bi-fold doors?

The majority of bi-fold doors are designed with a key locking multi-point locking system as well as a hidden inline tracking system. This makes 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 tend to be more expensive as they have more moving parts and complex elements such as running tracks. Whereas, sliding doors are simpler in their design and as a result tend to be cheaper.

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.

Bi-fold Doors – strong, secure and seamless

There are so many advantages to Everest aluminium bi-fold doors, in particular the seamless transition between the inside and outdoors. This three-fold example is our most popular option, and the materials and colours are designed to complement the style of your home perfectly.

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.
