Bi-Fold Doors

Aluminium bi-fold doors fold your wall away, opening your kitchen or living room straight onto the garden and filling the room with natural light. Every door comes with a choice of double or triple glazing, so summer evenings with the doors open don’t mean a cold house in January.

Push the panels back, and two rooms become one, ideal for the days you want the outside in. Close them, and the slim aluminium frames still let in more light than a standard door, keeping your home warm and weathertight through winter.

At BJH Windows, every bi-fold door is made to measure and fitted by our own team, from initial survey through to final installation.

Bi-Fold Doors Built by Trusted Brands

We supply and fit aluminium bi-fold doors from leading manufacturers, including Schüco, one of Europe’s most established names in aluminium glazing. This means every door you get from BJH has already been tested against strict European standards for weather resistance, thermal performance, and security, before it even reaches your home.

We supply the doors and install them too. Our own fitting team handles every job, so the same standard of care that goes into choosing the brand also goes into how your door is measured, hung, and finished.

Choosing bi-fold doors comes with a lot of benefits:

  • More natural light through larger glazed panels
  • A wider opening than sliding or French doors
  • Better insulation with double or triple glazing
  • Reduced noise from outside
  • Enhanced security with multi-point locking
  • Low-maintenance aluminium frames that don’t warp or rot

Bi-Fold Door Specifications

Every bi-fold door we install is built to a standard, not just a size.

  • 100mm profile for strength without a bulky frame
  • A++ energy ratings for heat retention
  • Double or triple glazing, so you choose the level of insulation
  • 23 standard colourways, with bespoke finishes also available
  • Heat protection glazing, keeping rooms cooler in direct summer sun

Security is a prerequisite of all our designs. Our aluminium bi-fold doors meet PAS24 enhanced security standards and carry Secured by Design accreditation, the UK police initiative for crime prevention through design. That means multi-point locking and reinforced frames as standard, not an upgrade you have to ask for.

Colour, Sizes, and Finishes

No two openings are the same, so no two of our bi-fold doors are either. We measure and manufacture each door to fit your exact space, rather than fitting your home around a standard size.

Choose from 23 standard colourways, including popular finishes like anthracite grey and white, or ask about a bespoke RAL colour to match your home exactly. Panel configurations are flexible too, from two-panel doors for a smaller opening to wide, multi-panel sets that fold away almost entirely.

Can Bifold Doors be Installed on any Property?

Bifold doors can be installed in most properties, but there are some factors to consider. For example, you will need to ensure that you have enough space for the doors to fold back without obstructing other areas or furniture. 

You may also need to check with your local planning authority if you live in a listed building or conservation area, as there may be restrictions on the type of doors you can install.

Are Bifold Doors going out of Style?

Bifold doors are still a popular choice for many homeowners and designers, and they have not gone out of style. In fact, bifold doors have been gaining popularity in recent years as people seek to bring more natural light and a sense of openness to their living spaces.

Bifold doors are versatile and can be used in a variety of applications, including interior doors, exterior doors, and room dividers. They are available in a range of materials, finishes, and configurations, allowing them to be customized to suit a wide range of design styles and preferences.

Can Bifold Doors Open From Both Sides?

Yes, bifold doors can be designed to open from both sides. Bifold doors consist of two or more panels that fold together in a concertina-like fashion, which allows them to be pushed to one or both sides of the door opening. 

The doors can be configured to open in either direction so that you can choose which side to push the doors to when you open them.

Do Bifold Doors Require Planning Permission?

Whether or not bifold doors require planning permission depends on several factors, including the specific circumstances of the property and the type of installation.

If you are replacing an existing door with bifold doors that have the same dimensions, then planning permission is not usually required, as this is considered a like-for-like replacement. However, if you are enlarging the opening or installing bifold doors in a new location, you may need planning permission.
