Aluminium Bi-Fold Doors

The perfect way to add a wow factor to your home, create a seamless link to
your garden and flood your home with natural light


Find the Right Bi-folding Door For You

Our aluminium bi–folding doors are stylish and modern, easy to use and meet the highest standards of security and energy efficiency. They can also be designed to fit large or small openings, with a variety of opening configurations to choose from.

Frame Thickness

Our bi-fold doors are available in a selection of frame sizes to provide a choice of solutions for different opening sizes. You may prefer slimmer frames with more sashes or thicker frames with fewer sashes.


As well as our standard threshold, we offer various solutions to allow for easier access. These include lower thresholds for external bi-fold doors and flush-thresholds for internal doors, for both PVCu and aluminium.


We can offer a range of lever and D handles in a choice of finishes and colours. We’ll help you find the right option to perfectly complement and enhance your new bi-fold doors.


Our aluminium bi-fold doors are most commonly white, black or anthracite grey, however you can choose any standard RAL colour if required. Our PVCu bi-folds also have a range of woodgrain finishes.
