Aluminium bi-folding doors


Why choose our made-to-measure aluminium bi-folding doors?

Folding back neatly in sections, bifold doors are the perfect way to provide easy access to whatever you choose to put behind the door while still providing a much-needed separate space away from the rest of your home. Whether inside or outside your home in gardens or living areas, create an excellent entranceway or split larger rooms without losing your sense of space.

  • A maximising choice: Have maximum control over the style of the doors thanks to the endless customisations and options you can choose to make these doors yours. From expansive glazing to high levels of safety and security, you’ll be getting the highest quality and standards with their installation, even at standard.
  • A performing choice: No matter how you choose to customise these doors, they will always provide maximum performance. Their four stainless steel wheels ensure smooth and consistent operation, while the unique, flush line pop-out handle allows for maximum door opening and square stacking of panels. They are even tested to PAS 24 and certified under the Secured By Design scheme for the best security.
  • An upgradable choice: While our standard designs offer some of the highest performance on the market, we offer even more options to improve them further. Whether you’re looking for heavy-duty rollers, chamfered and square-bead options, or low-threashold options, we always ensure our doors meet your individual needs and tastes.

A Performing Choice

With exceptional wind and water performance, our doors also benefit from the highest level of safety and security thanks to their fully cycle-tested flush pop-up handles. The floating mullions even create a seamless transition between the inside and outside for uninterrupted views.

On a chilly day, relax and enjoy the views to outside with no draughts and no leaks, safe in the knowledge that the doors have been tested to the very latest weather performance tests. And, when the sun shines, slide the doors open smoothly and effortlessly and make the most of that inside/outside space.

An Innovative Choice

The unique flush pop-out handle creates ease of operation for all homeowners so that you can remove the need for additional unsightly handles. Paired with heavy-duty stainless steel compact rollers, full symmetrical frame sightlines and large glazed areas, they are one of our most modern options.

Bi-fold doors remain as aspirational as ever, transforming even the most mundane rooms into light, contemporary spaces. Slim sightlines mean more glass and less frame, and, from the handles to the finish, our attention to detail shines through.
