Origin Bi-Folding Doors: OB-36, OB-49, OB-72 & Soho OB-36+

When exploring Origin door configuration options, you’ll quickly see why Origin’s bi-folding door are so superior – there’s simply a word of choice. Origin can cover up to a massive 9.4 metres wide with 8 doors and up to 3.025mm high. Individual doors sashes can be manufactured as narrow as 400mm and as wide as 1200mm. You choose how they open and close – if they fold in or out, and which way they slide.

From 5 Star’s perspective, it’s not just that Origin gives you almost any option. It’s that every option, in each system, in every colour, with all thresholds, works perfectly, arrive on time and is supported by Origins world class British factory - It’s an open and shut case.

Origin Bi-fold Doors are available in almost any colour, including popular black, white and all the modern greys. Origin can manufacture in over 150 different RAL colours and come with a dual colour option (different inside and out). Origin’s range includes wood-grain colours.

In order to give the Origin Bi-fold Door a flawless finish, Origin aluminium is coated with the highest-grade powder available. Applied using an electrostatic process after a special pre-treatment, it is then cured at 200°C to form a robust coating that is tougher than conventional paint, whilst maintaining a completely smooth surface. Origin doors are resistant to scratches and are unlikely to fade.

One of the most important handle options, Origin let’s you consider, is having no handle on the outside, ultimate security if the door is not used as an entry point.

Handles, D handles and Slave handles are available in a choice of finishes, styles and colours. 5 Star can supply most bi-fold orders in Solid Stainless steel when chosen at the time of order. Modern homes tend to choose silver colour while older properties tend to go for a gold or black finish. If you have young children in the house, Stainless-steel handles are a great choice because they require less maintenance, are incredibly durable and are easy to clean. You’ll also want an easy-to-pull handle, so children can use easily.

Origin bi-folds are typically much harder to break into than many French doors and sliding doors because they employ a unique eight-point locking system built into the traffic (master) door (5 more locking points than many competitor doors) and have passed PAS23/24 tests. Chamfered 20mm bolts offer smooth operating when engaging, as well as providing maximum compression for security and weather resistance.

Origin bifolds also boast deep throw 25mm security hooks - the deepest position available today. The Origin lock delivers the best in both security and weatherproofing. Origin uses a combination of solid cast Yale security handles with high performance fixing bolts and a British Standards accredited Magnum security cylinder, proven to protect against snapping, picking, drilling and bumping.

A bi-fold threshold is the track which the door carriage slides in, to open and close. Origin recommends a weathered threshold (also known as a ‘rebated’ threshold), which can be sunk into the floor, it leaves a minimal lip, (just 14mm from outside to in) the seal on the bottom of the bi-fold door compresses against the lip to create a protective weather tight seal.

Non-weathered thresholds offer a flat transition between in and outside. As there is no raised section, however, because the door seal doesn’t have a solid lip to compress against, optimal weather performance is not guaranteed. This type of track is recommended for internal or sheltered areas only.

Aluminium is not a thermally efficient material, which is why Origin have developed thermal polyamide breaks, designed to limit the heat transfer from outside to in. This, with sophisticated weathertight seals, ensures it’s warm in the winter, cool in the summer.

In real terms, Origin helps reduce your energy bills. The U-Value of doors measure how effectively they insulate, lower U-Value are better. The Building Regulation require doors and windows to have a U-Value of 1.6 W/m2K and for replacements, 1.4 W/m2K. Origin exceed British Building Regulation requirements across all the range.
