Premium quality uPVC Bi-folding Doors designed & manufactured in the UK


Like our aluminium bi-folding door, our uPVC timber alternative bifold will satisfy your desire for more light and space and offers a stylish link to the world outside, spanning up to 6 metres. When it came to developing our own uPVC bi-folding door, we specified that the suite of profiles must be purpose-designed for the job and that is why we believe we offer the ‘best of bifolds’, with slim sightlines, dedicated accessories and durable, trouble-free performance.

Our KAT uPVC bifold is one of the most successful products we have ever launched and given the durable, innovative design, we have extended the warranty on this product to 10 years.

It has been severe weather tested to BS 6375/1:2009 and is certified to PAS23 and PAS24, making this the best performing uPVC bifolding door in the UK.


Material Information


We have a very wide range of timber alternative grain finishes for our uPVC bifolds including dual colour  with different colours each side. We offer a 10 year warranty on all timber alternative foil finishes on uPVC. And of course, every finish is virtually maintenance free.




We also offer you a complete range of accessories from handles, to threshold options, to opening configurations.

Our bifolding door cranked handles are available in White, Black, Gold or Chrome with intermediate handles available in the same finish.

A D hinge is available in either White or Black.

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 doors are designed to discourage a determined intruder, thanks to our high security locking systems.  

The master door has a high security three hook lock and the intermediate handle operates a shootbolt to provide intermediate security. These features help prevent our bifolds being lifted off their base channel or being jemmied when closed.

KAT’s uPVC Bifold Doors are fitted with the Ultion 3 star Diamond rated cylinder for your security.
