Luxury Kawneer aluminium Bifold Doors designed & manufactured in the UK AA3720


Thanks to the influence of Grand Designs and our desire for more light and space, 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 Kawneer Bifold doors are the ultimate alternative to Schuco Bifolding doors.

KAT Aluminium bifold doors offer the best weather resistance of any bifold in the UK and are made to bespoke sizes to suit your project and are available in seven colours from stock. Our Master door handles are designed exclusively by us and are made from stainless steel.

Product Awards




We manufacture KAT Kawneer bifolds in Cheshire.  Aluminium is the perfect material because it allows for narrow, aesthetically pleasing frames, is extremely strong and very low maintenance.

Our doors are currently the highest performing doors in the UK in tests against wind, water and air pressure (severe weather tested to BS 6375/1:2009). 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 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 doors we also offer you a complete range of accessories from handles, to threshold options, to opening configurations.

Our KAT bifolding door handles are luxury products, made exclusively to a KAT design and crafted from Stainless Steel and guaranteed for 10 years.

Please consider your choice of ancillary hardware carefully because that is what you will eventually notice most when your products are installed. Check out the finishes on our handles because it is attention to detail that helps make this unique product range so exciting.




Safety & Security


Our bifolding doors are designed to discourage intruders, thanks to the master door security locking system and intermediate handles with shootbolts which can also be supplied with key locking. We fit a 3 star diamond rated cylinder to all Aluminium Bifold Doors. The whole system conforms to PAS 24:2016 security standards.

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