Whether you have a period home, new build, unconventional property or quaint cottage, there’s a bi-fold which will complement your home and allow you to enjoy it in a completely new way.
Created bespoke to ensure you can make the most of your space, Origin bi-folds range from one to eight door sets and individual doors can be manufactured as narrow as 400mm, as wide as 1200mm and as tall as 3000mm. You can choose how they open and close – whether they fold in or out, and how they slide – to meet your exact needs.
Choose from either the slimline OB-49 or classically styled OB-72.
Choose how your doors open and the direction they fold in.
Select whether you want a weathered or non-weathered threshold. Read more
Decide whether you want your doors to open to your inside or outside space.
Choose from a selection of stunningly designed handles from our ranges.Complementing the rest of the Origin range, our bi-fold doors create a harmonious look with existing door and window systems – right down to the slim profiles. The large expanses of glass sit within an ultra-strong aluminium profile, and you can choose the OB-49 or the OB-72, both with their own individual characteristics to suit different styles.
The key difference between the OB-49 and the OB-72 are the sightlines they achieve. In the table below, we run into the performance and differences between the two.

Creating that truly seamless link between your home and outside space is all in the threshold. We recommend a weathered threshold, which can be sunk into the floor. It leaves a minimal lip but provides a protective weathertight seal.
Non-weathered options offer a level floor finish and create a seamless transition between the inside and out. Non-weathered options are largely recommended for internal usage.
When you think of bi-fold doors, you may envision wide expanses of glass with light flooding in without much variation, but it is possible to personalise your bi-folds to ensure they truly complement your home and your style.
Taking a traditional design and making it cool and contemporary, you can opt for Georgian bars. By placing bars vertically, horizontally or both, our steel-style doors create a classic style and an extra sense of cosiness while still allowing for vast expanses of light.
An intelligently engineered short wheelbase carriage assembly with four wheels, manufactured from a high-grade acetal, guides the doors along the track seamlessly, enabling them to open and close with ease. It’s quality you can see, feel and admire.
