Open Up to the Outside


Bi-fold doors are a set of 2 or more, predominantly, glass doors that open in a concertina style and neatly fold flat to one or both ends when opened. They open by folding back the panels and stacking against each other either to one or both sides. Bi-Folds are sometimes referred to as concertina doors, folding doors or panoramic doors. The main reason for having Bi-Folding Doors is to help you make the most of the space in your home and other areas such as an Orangery. Depending on the number of panels and configuration you choose, Bi-Folding Doors can have a primary door for daily use without having to slide all the panels open but once they are open they truly bring the outside, in.

Unlike Patio Sliding Doors that can only remain half open when opened, Bi-fold doors fully open to seamlessly connect your living space with the outdoors.

Safety First

The stainless steel wheels and tracking system ensure a smooth opening that will stand the test of time and as standard comes with a roller mechanism for a safer sliding operation. We care about your young ones and to prevent trapping fingers a child safety system with a continuous hinge helps to reduce the chances of fingers being trapped between the leafs.


Security Makes Our Bi-Folds Unique

Regardless if you choose our Timber or Aluminium Bi-Folds, a combination of a multi-point locking system, robust shoot-bolts, high security hinges and laminated glass make our Bi-Fold Doors one of the most secure on the market. The lock cylinder has been tested to BS EN 1303 and all our Bi-Folds are internally glazed to prevent glass being removed from outside from opportunist buglers.

It's common to hear that you can have a maximum of 6 leafs up to 6.4m wide but with our tried and tested Bi-Folds they can achieve at least 8 leafs up to 9.6m wide! Each Bi-Fold Door leaf folds smoothly onto each other and are held together with magnetic pads to allow in maximum light when opened with undisturbed views.

Common Questions About Bi-Fold Doors

At Decor, we know when choosing new Bi-Folding Doors can be a exciting project. So to help you make the correct decision here are some of the most common questions we get asked that you might find useful.

What is the Maximum Width Per Panel/Leaf on a Bi-Fold Door?

A lot of our manufacturers can achieve up to 1.2m per panel but a handful only go up to 1m per panel

Can Bi-Fold Doors Open In as well as Out?

Bi-Fold Doors have been engineered to open both in and out, depending on the needs of your project. Most homeowners choose to have doors open outwards as it provides more space in the room for furniture and a lot of home owners who have loft conversions have them opening in for ventilation with a Juliet Balcony.

How Secure are Bi-Fold Doors?

Bi-Fold Doors in Aluminium or Timber offer a fantastic level of security due to our secure multi-point locking system that locks at multiple points along the sliding track. Along with high security hinges, laminate glass and glazing beads on the inside helping to prevent the glass being removed from the outside of the door ensure that your Bi-Fold Doors are near impenetrable

Do I Need to Obtain Planning Permission for Bi-Fold Doors?

Depending on if you live in a Conservation Area, Bi-Fold Doors are normally covered under permitted development rights. We always advise to check with your local authority, which Decor can help advise on and if need be make the phone call on your behalf. 

Do I Need to Obtain Building Control for Bi-Fold Doors?

If you are altering a door opening to install Bi-Fold Doors, you will most likely require a Building Notice. This is to ensure the new opening is capable of withstanding the extra weight and will most likely require a new RSJ/Lintel to support the weight above.

How Much do Bi-Fold Doors Cost?

Bi-Fold Doors typically cost more than most other door types in the same material, this is due to more material, more glass and extra moving mechanisms but are worth every penny for the aesthetics and unrivalled views. 

We would say our Bi-fold Doors are a more of an investment than purchase due to their durability, slim frames (to enjoy all that light that will flood in) and thermal efficiency that both our Timber and Aluminium can offer.
