Aluminium Bi-fold Doors

Luxury Aluminium Bifold Doors designed & manufactured in the UK


Thanks to the influence of Grand Designs and our desire for more light and space, Aluminium Bifold Doors have become a phenomenon. If you have the space to stack the Bifold Doors to the left or right, or on both sides, when they are fully open, then a Bifold Door could be ideal for you. Bifold doors can be fully opened to around 90 per cent of the full opening width, allowing you the flexibility to let in lots of fresh air and move around freely. On days when you don’t wish to open the doors fully, you can choose to have a single traffic door, allowing you easy access between your home and garden all year round. KAT’s Bifold doors are the ultimate alternative to Schuco Bifolding doors.

KAT Aluminium bifold doors offer exceptional weather resistance and are made to bespoke sizes to suit your project.

Aluminium is the perfect material because it allows for narrow, aesthetically pleasing frames, is extremely strong and very low maintenance.

Our bifolding doors have been independently tested against wind, water and air pressure. They come with an extended 10 year warranty and our simulation tests have shown that they have a life expectancy in excess of 25 years.


Material Information


Aluminium is the optimum material for manufacturing windows and doors and that is why it is widely specified by Architects for most serious new build and refurbishment projects.

Aluminium bifold doors require very little maintenance, just an occasional wipe with a damp soapy cloth and a regular check to ensure the track is kept free from grit and small stones to ensure the doors continue to run smoothly. Aluminium is more resistant to the elements than uPVC and is not likely to warp or rot. We offer a 10 year warranty on standard paint and a 25 year warranty on Marine Grade paint.




With our huge range of exclusive aluminium bifold doors we also offer you a complete range of accessories from handles, to threshold options, to opening configurations.

A lever handle is fitted to the master or traffic door, in a choice of seven finishes; Anthracite, White, Gold, Stainless Steel, Black, Chrome or Rose Gold.

We fit a black handle and black hinges to the intermediate doors which allows for flush stacking panels when the doors are fully open.

Please consider your choice of ancillary hardware carefully because that is what you will eventually notice most when your products are installed.



Safety & Security


Our bifolding doors are designed to discourage intruders, thanks to the security hinges, locking mechanisms and a unique heavy-duty roller design to provide the security and reliability demanded in high traffic applications.

All these elements prevent our bifolds being lifted off their base channel or being jemmied when closed.

An upgrade to PAS 24:2016 security standards is available on request.
