Origin Bi-fold Door Configuration

The Origin Bi-fold Door can be completely tailored to your needs, with all of the details exactly as you want them. All elements are bespoke and made to measure to your individual requirements and style.

All the products from the Origin Home Collection are sold via a network of local installers who will source the glass, as well as undertake and guarantee your installation. These installers are completely separate to Origin, meaning your contract will be with them and, therefore, any remedial work required would be carried out by your installer. More information.

Once you have found your local installer, you will be able to work with them to configure your door set to your requirements. However, to get you started on this journey and provide an overview of the options available to you, please see the bespoke elements below. Or find your local installer.

1. Material

The material of the bi-fold door you choose is an important factor to consider. All Origin Bi-fold Doors are made from premium grade aluminium, and we only use prime billets. This means that none of the aluminium we use has been made up from re-melting scraps, giving us more control over the overall formation of the doors and allowing a greater finish to be achieved.

This innate strength means we can provide bi-fold doors that are physically secure, energy efficient and extremely durable. Aluminium frames can easily accommodate complex door layouts, such as moving corner posts and bay setups, without being too heavy.

Configurations, Sizes and Options

The configuration you choose for your bi-fold doors will depend on the space you’re looking to fill and the size of the opening you have available. They can be configured in a number of different ways, so knowing about the options can help you to make the right choice for your home.

2. System / Sightline Options

The Origin Bi-fold Door is available in sightlines of 36mm, 49mm or 72mm.

OB-36+ SohoOB-36+ (Soho)With sightlines of just 36mm this is the slimmest bi-fold door available.
OB-36+ ContemporaryOB-36+ (Contemporary)Offering sightlines of 36mm, 49mm or 72mm in a more traditional style.

Start configuring your door by choosing the sightline option that’s right for your home and the purpose you want the door to serve.

3. Size

With Origin, you have complete freedom over the size and configuration of your doors. Once you have an overall size, you can choose your preferred configuration and how many individual door leaves and direction of opening you want.

For example, you may want fewer, wider doors to maximise the view, or, to accommodate a desired configuration, you could opt for more leaves. In this instance, the individual leaves would be narrower.

4. Configuration

In order to configure your door, you’ll need to specify whether you want them to open inwards or outwards. As with all tailored elements, the choice is yours and will be dependent on the space you have available as well as your individual preference.

Number of doors/panels and opening options

Bi-fold doors are available with a huge range of panel options and opening options, and the choice you make will depend on the space you have available and the best functioning for your home. Configurations for our Bi-fold Doors can be found in our product brochure.

Options include:

Two panelsTwo panels
Three panelsThree panels
Four panelsFour panels
Five panelsFive panels
Six panelsSix panels
Seven panelsSeven panels
Bi-fold doorsContemporary OB-49 External Door 1+3 Bi-fold Door

Origin Bi-fold Doors can be fitted with a traffic or access door. A traffic door is part of the overall bi-fold set, but can act as a traditional single door when the doors are closed. This door is a hinged door that opens and closes on its own to provide easy access in and out of your home, without having to open your bi-folds all the way. A traffic door is also fitted with a built-in locking mechanism.

We usually recommend choosing a configuration with an odd number of panels as this would allow for our unique multi-point lock to be used and provide you with an everyday access door. However, if you choose a configuration with an even number, you can incorporate a traffic door within it. e.g. If you have a 4 door set, you can choose a 3+1 configuration. Your local installer will be able to talk through the options with this.

With a choice of over 150 RAL colours, including dual colour options and two woodgrain colours, you can tailor your Bi-fold Door to your personal taste and style. If you opt for one of our popular colours, this will be available on a shorter lead time, so once you have configured your doors, you could have them sooner than you originally thought. Find out more about lead times on specific colour choices.

6. Glazing

When you buy an Origin Bi-fold Door, the glass is sourced and installed by your local installer, but they can be specified to accommodate either double or triple glazing - whatever suits your needs.

The tolerances on each component of our Bi-fold Doors are tested to make sure they can bear the weight of the glazing option you choose.

Double Glazing

Double Glazing

  • Weighs less than triple glazing so does not put as much pressure on the frames
  • Good sound insulation
  • Sufficient energy efficiency for the UK climate
Triple Glazing

Triple Glazing

  • More thermally efficient
  • Allows less heat to escape for your home
  • Superior noise reduction and acoustics
  • Lower U-Value than double glazing

7. Threshold Options

When configuring your door, you will have the choice of a weathered, non-weathered* or low thresholds.** You should consider where you are planning to install the doors as well as how exposed to the elements they will be.

*Only available on OB-49 and OB-72
**Only available on OB-36+

Weathered Threshold

Weathered Threshold

includes an upstand which provides protection and keeps a home watertight.
Non-weathered Threshold

8. Handle Options

The finishing touch to your door configuration is your handle choice. Choose from modern and elegant handle styles to match your tailored design. You can decide on a standard aluminium or stainless-steel finish, and some of our handles can even be colour coordinated, so you can match or contrast with your chosen door colour.

9. Lock Systems


Depending on the configuration you choose, Origin Bi-fold Doors can be fitted with our unique 8-point locking system – this is across the OB-36+, OB-49 and OB-72. This lock meets all of the latest security standards including PAS 24 and the police preferred Secured by Design accreditation.

Barrel Options

Our OB-36+ and OB-49 both come with a 3-Star Diamond, British Standard Kitemark locking barrel as standard. These barrels are proven to protect against snapping, picking, drilling and bumping to help prevent intruders from gaining access to your property.

Our OB-72 can be upgraded to include a 1-star barrel which will make forced entry difficult.


The hinges fitted to Origin Bi-fold Doors are specially designed to help withstand attacks and lessen the chances of intruders being able to access your home.

10. Accessory Finishes

The hinges, running gear, D-handle and slave handles of an Origin Bi-fold Door can be colour coded to your door colour, can be contrasted or are available in stainless steel.

For the lever handles, those in the popular Contemporary Aluminium are available in black, white or chrome. Handles in the Contemporary Stainless Steel are also available to be colour coded or specified in any RAL.

The gasket seal is also available to be specified to match your requirements, with eight colours available.

Your local installer can advise on the recommended colour options available, but the end result is tailored to you.

Some of our competitors offer guarantees of up to 25 years, but this can be misleading and often doesn’t cover every element of the doors. Our guarantee of up to 20-years covers the door and each of its manufactured parts, making our offering unique in the market.

Should it be required, your installer will be the one to undertake any remedial work and they will work with us for ancillaries and do the labour themselves, so be sure to check out the guarantee on their installation and the glass they have sourced.
