Aluminium Bi-Folding Doors



Aluminium Bi-folding and Multi-folding doors are versatilie and practical

Rejuvenate your home and create an open, flexible and modern space for living with our Aluminium Bi-Folding Doors. These high performance doors are becoming the modern choice for a patio or garden. The strength of the aluminium means that their profiles can be a lot slimmer than uPVC or timber doors, and makes them a lot more durable and less prone to weather resistance.

Every single Bi-folding or Multi-folding door is manufactured to the highest standard without a single compromise on strength whilst being slimmer and more streamlined than their traditional patio counterparts.

Providing up to 90% clear openings, our Bi-Folding doors are the slimmest on the market – with sightlines meeting just 108mm. Our bespoke designs perfectly match the existing style of your home, allowing natural light to flood in whilst providing the opportunity to bring the outdoors, indoors.


The OB-49 exceeds British Building Regulation requirements for optimum thermal efficiency. New for 2019 this slim line door has been re-engineered from the industry-renowned OB-72. Origin OB-49 Bi-Fold Door with 49mm profile provides an unbeatable panoramic view of your surroundings.


Designed and manufactured in Great Britain and made from the highest-grade aluminium, the Origin Bi-Fold Door is an expertly crafted door system, perfect for any type of home.
