Origin, the UK’s leading manufacturer of premium aluminium windows and doors, has launched a brand-new market-leading Sliding Door – the OS-29+.
This is not an updated version of its OS-29, but rather, a completely new sliding door system that combines minimalist design with cutting-edge performance.
Superior thermal efficiency
The new OS-29+ is able to achieve U-Values as low as 0.78 W/m2K, making it the most thermally efficient aluminium slider available.

Ultra-slim 29mm sightlines
Engineered from the highest-grade aluminium, the OS-29+ boasts ultra-slim sightlines of just 29mm. Large glazed areas and minimal sightlines make it ideal for modern properties, offering expansive views out of a property whilst maximising the amount of natural light inside.
Engineered for perfection
The OS-29+ features concealed running gear and optional flush stacking, which gives the system a refined, chic and clean finish.
Unbeatable construction
Manufactured by Origin at its state-of-the-art facility in Buckinghamshire, the OS-29+ undergoes rigorous checks at every stage of production to ensure that every system is of consistently exceptional quality. Each product is made bespoke to exact customer specifications. With over 150 RAL colours to choose from, there’s a shade to suit every style.

The Sliding Door also benefits from an exceptional finish thanks to Origin’s Qualicoat-accredited in-house powder coating facility.
A signature style across the Origin range
Origin’s sleek, tactile, high-end signature knurled handles tie perfectly into the full product suite, allowing a cohesive look across bi-folds, internal doors, windows and sliders.
Safe and Sound
Like all Origin products, security is built into the design. Featuring a multi-point lock and a 3-Star Diamond Cylinder, this door exceeds all required security accreditations and achieves PAS:24.
Engineered for excellence
The OS-29+ offers the industry a fresh new design. With market-leading performance and sleek features to match, beauty has been engineered in every detail.
