Comparing the differences between the systems.
OB36+
OB36+
The OB36+ introduces a next generation of design and a new level of refinement for your home. Ultra‑slim 36mm profiles combine with advanced engineering to elevate security, performance, and aesthetics.
With thermal efficiency a key design priority for our in‑house Research and Development team, the OB36+ is not only our newest external door, but it’s also our most energy‑efficient one too. Delivering U‑Values as low as 0.78 W/m2K, it offers maximum performance with a minimal environmental footprint.
OB49
OB49
The OB49 offers a versatile design that feels at home in both modern and traditional properties. Its proportions create a balanced, harmonious aesthetic, while full customisation allows you to tailor every detail to your style, taste, and practical needs. Whether you’re enhancing a period cottage or refining a contemporary extension, it adapts effortlessly to its surroundings.
Developed from our award‑winning 72mm system, this design builds upon everything that made the original so successful while offering slimmer sightlines to improve light levels and enhance the sense of space.
OB72
OB72
The OB72 is the original Origin External Door. It’s the design that set the benchmark for everything that followed. Created when our founders recognised the need for better engineering in aluminium bi‑folds, it established the core principles of precision, quality, and reliability that continue to define every system in the Origin collection today.
With 72mm sightlines, it delivers a more traditional aesthetic with its wider profiles and creates a bold architectural statement that suits both classic and characterful homes.
With three sightine options available, there are three possible ways to frame your world. In the table below, we run into the performance and differences between them.
| OB36+ | OB49 | OB72 | |
|---|---|---|---|
| Sightline | 36mm | 49mm | 72mm |
| U‑Value | Up to 0.78W/m2k | Up to 1.1W/m2k | Up to 1.1W/m2k |
| Guarantee | Standard: Up to 20‑years Marine Environment: Up to 10‑years (frame): up to 5‑years (hardware) | ||
