Origin OB-49 bifolding door review.

New for 2019, this sleek and slim bifolding door comes with all the quality, functionality and desirability of the classic Origin bifold.  It has the same components with substantially thinner sightlines and an overall square and more modern appearance.

The OB-72 remains available with excellent reasons to consider it, despite being a thicker profile.  We go into these reasons later in the article.  Now you have two bifolding doors available from Origin, both having the same high quality hardware, smooth-glide action, incredible personalisation options and the legendary Origin customer service.

Some of the best bifolding doors on the market remain unchanged over the years. The Schuco ASS70, Reynaers folding doors, Centor, Solarlux and others all offer great propositions for a new folding door in the home.  Sunflex has the mid-range SF55 model, which is another excellent proposition, made in Germany and also high tech and slim.  However, the market has changed when it comes to new patio doors for the home.  Sliding doors are back and as popular as a bifold.  Steel replacement systems are very on-trend.  So what does the new Origin OB-49 bifolding door offer as a proposition compared to some of the already excellent brands on the market? We’ve picked out four good reasons to consider the latest Origin product as part of your home renovation project.

Thin bifolding door sightlines.

The door industry markets the sightlines of its bifolding doors heavily.  On the one hand, sightlines are one of the best reasons to choose aluminium over upvc products.  However, looking at the overall product proposition remains important and not just sightlines.  How the doors slide and fold, the quality of the hardware, the guarantee and the overall product proposition is what matters more.

However, if a slim bifold is what matters to you, then Origin OB-49 bifolding doors don’t disappoint. They now come with sightlines of just 110mm at the door mullions compared to 154mm for the OB-72 model.  And they now come in the top five slimmest bifolding doors, even beating Schuco and Sunflex.

Thinnest aluminium French Doors and single doors.

What you may not know is that bifolds are ideal as single doors or French doors.  Most installers will use a dedicated residential door system such as the very good Aluk Optio 58BD or the Smart Systems Alitherm and Alitherm Plus models.

On a set of French doors in the home Aluk doors offer a 209.5mm sightline where the doors lock in the middle.  Smart systems give you a 166mm sightline. An Origin door will provide you with 110mm.   The overall 49mm sash combined with the frame provides you with neat proportions on a single door too.

Therefore, if you’re looking at a new back door or set of French doors, there narrow sightlines of the Origin bifold, made as hinged doors gives you very good looking slimline doors.

The Origin OB-49 bifolding door as a steel-look product.

The current trend for doors and windows in the steel-style suits both traditional houses with old metal windows. Also ideal for this latest generation of doors is new extensions wanting industrial-styled doors, New York screens and residential windows.

It’s worth point out that there is no dedicated steel-look bifold. Every door is simply customised with aluminium glazing bars and different glass units, achieving the desirable multiple panel effect.  So you can have this appearance with any door on the market. However, steel windows and doors are slim. Therefore, the thinner the bifold sightlines, the more credible the overall appearance.

Up to now, products such as the Visofold 6000 bifolding door, offered one of the most credible steel look bifolds. This remains the case with its 98mm door mullions and overall excellent appearance.  However, the OB-49 is now another contender, with all the other benefits of Origin bifolds such as colour matched gaskets, the more extended warranty and the better door components and handles.

Make your existing Origin bifolds thinner.

Finally, it’s worth pointing out that the new Origin OB-49 bifolding door uses the same outer frame and components as the existing OB-72.  Therefore, one quirky upgrade to a current set of Origin doors is to make them thinner.

It is entirely possible to replace your existing door panels and glass with new panels and glass using the thinner system.  There is a fair cost involved in doing this, but if you were so inclined, it’s possible to do this and upgrade your doors to the new thinner model!

Origin OB-49 bifolding door compared with the OB-72.

The current and retained OB-72 model remains a well made, high quality bifolding door with a 72mm sash profiles and a more traditional chamfered appearance. The OB-49 uses the same frame and components having a 49mm frame, square beads and an overall square look to the door profiles. The slide and fold action remains the same as does the quality, the locking systems and other features found in Origin folding sliding doors.

The OB-72 being a larger door also offers bigger door sizes and an open corner option, whereas the new slimline bifold does not.

Some features found on the classic OB-72 bifold are not available with the new slimline product.

The open corner option is not available, but a fixed corner post option is.  This new door only comes with a Hafi premium handle, and you can’t have the Yale option. This is not a disadvantage as not only do the Hafi handles look better, they look especially good on this slimline door. Nor can you have a locking slave door handle. Woodgrain options we understand are not available with this product too.  Should you choose a single or double door set, these don’t come with the midrail option.

The door sizes are smaller with this new door, but for replacing old patio doors or a new extension, the heights available meet the vast majority of customer requirements.

Other bifolds to compare with the OB-49 from Origin

It’s worth mentioning the Smart Systems Visofold 6000 again as this has recently launched with a new sash section specifically for a steel-look option.  Check this out, it really does work well.

Other bifolds with similar dimensions include the Sunflex SF55 model, with just 5mm difference in the door mullion sightlines.  There are a lot of great features on this door and it’s worth considering too.

Origin OB-49 bifolding door review. Summary and Conclusion.

origin

For years, consumers wanting a slim bifolding door needed a Schuco or similar German-made product. Origin has pulled one out of the bag with their new bifold where many recent new models looked to replicate the 120mm sightlines of the Schuco ASS70 model. Origin went one better, reducing the aluminium profile right down beyond industry expectations.

The Origin OB-49 bifolding door has all the quality of the OB-72 with standout aesthetics.  Homeowners benefit from a brand new door with style and maximum glass area for better views — the trade benefits from the legendary Origin service with fast lead times and reliable service all-round.  Loyal Origin installers now don’t need to point customers looking for a slimline door to alternative systems.  So if the chamfered and bigger sizes of the classic Origin were not for you, there is now an excellent alternative.  Best of all is the colour choices, personalisation options and Origin manufacturer guarantee.  There is, of course, the full range of Origin windows, sliding doors and front doors giving an entire brand and single-point guarantee for the home too.

While this review focuses on the bifolding door, the availability of single and French doors is a ‘twist of fate’ that it surpasses so many other door brands for aesthetics with more options such as the colour matched gaskets.  Yes, there are minor compromises when using a folding system as a hinged door, but for aesthetics and brand kudos, the OB-49 is hard to beat.
