Product Features


The secret behind the renowned smooth-slide action of the OB-72 bifolding door is the highly-engineered door hardware.

A bifolding door needs dedicated bifolding door bottom rollers and top guides. These precision-crafted carriages come with four wheels, high-grade acetal and other engineered components. The end result is a light, quiet and seamless opening, letting you slide and fold the doors with ease. Importantly the quality of the folding hardware is seen and felt as well as admired.

In the open position, magnetic catches can help hold the doors in place while you operate them. And they help keep the doors together when fully folded back.

The Q-Lon gaskets sealing your new bifolding doors do more than keep the weather out. Made from a different material to conventional rubber seals, these are easy to clean, durable and look better. Above all they provide a valuable finger-safe feature, preventing injury to young fingers. And they come colour matched to your doors if you want them to - another exclusive feature available only with Origin doors.


With glass being the primary component of any door, it's important your glass offers you security, safety, comfort and optional convenience.

As standard doors come glazed with double glazed units with toughened safety glass. We use a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill.  This specification results in a strong and energy-efficient glass unit.

Also available is laminated glass for enhanced security and forming part of the security tests. This glass holds together when broken thanks to a layer between each sheet of glass. So in the unlikely event of an intruder breaking the glass, they're unlikely to get through it.

Origin OB-72 bifolding doors come in over 150 different RAL shades to choose from. Therefore there is a colour to match your tastes, property style and location of your doors.
As well as classic white or contemporary grey or black, there are virtually unlimited choices. Another made-to-order feaure when choosing an Origin product.

Even more choice comes from a different colour inside and out. A dual colour option lets you colour match the inside of your doors to your decor and the outside to your property - ideal for older houses.

And with every colour having a matt, gloss or satin option, there is even more choice of colour for you.

The specialist polyester powder is applied to your aluminium doors only by certified and approved applicators. Durable yet smooth to the touch, powder-coated doors look great for years to come with only routine cleaning of the surfaces required to keep them looking like new.

And if your property is in a coastal or exposed location, we offer enhanced protection with special paint guarantees, subject to individual application.
