An aluminium bi-folding door can be factory sprayed, powder coated or anodised to accommodate all tastes. There are hundreds of colours to choose from, whether your choice is just aluminium or aluminium & timber clad, we can coat it to your desired finish.


We utilize the Fold‘N’Slide hardware brand which is uniquely designed, independently tested and accredited. All our rollers on our aluminium bifolds are fully encapsulated within the track.


An important choice to make when purchasing your alumininium bifold doors is what type of glass to put in them. Glass has a significant effect on the heat your house loses at night, the heat it gains during the day and noise levels from outside. Glass helps to determine the level of comfort, security and privacy.



Aluminium Bi Folding doors can be installed in a huge range of situations, in fact we offer you with so much flexibility and choice that the solutions are almost endless.



Security is one of our main concerns on door design, that is why the security and integrity of our aluminium bi-fold doors have been tested to destruction in UKAS approved testing laboratories.


All of our bi-fold aluminium systems have been thermally simulated to indicate the true thermal value, helping you choose the right option for your property and helping you save money on your fuel bills.


Our aluminium bi-folds have been tested at a UKAS accredited testing station and passed the PAS23 weather test to extreme weather conditions.
