More Aluminium from Artisan
Choosing 
aluminium sliding patio doors is about more than just adding an entrance to your garden; it’s about removing the boundaries between your home and the outdoors. Known for their "whisper-quiet" glide and ultra-slim profiles, Origin sliding doors are a premium British-engineered solution for any modern home.
offers two primary sliding door systems—the Artisan (OS-20) and the Patio (OS-29, OS-44, and OS-77). Whether you want a near-frameless look or a more traditional sliding door feel, there is a configuration tailored to your vision.
The "sightline" refers to the width of the frame where the two doors meet. The slimmer the sightline, the more glass you have.

Sliding Doors?
Despite the immense weight of the premium toughened glass, an Origin door can be moved with a single finger. This is thanks to a precision-engineered stainless steel track and high-grade rollers that ensure a smooth, silent operation for decades to come.
The OS-20 Artisan Slider is the flagship of minimalist design. With a meeting style of just 20mm (barely the width of a 20p coin), it creates a "wall of glass" effect that floods your living space with natural light even when the doors are closed.
Every door is equipped with a polyamide thermal break, designed to limit heat transfer. The new OS-29+ model is particularly efficient, achieving U-values as low as 0.8 W/m²K, keeping your home warm in the winter and cool in the summer while reducing energy bills.
Security isn’t sacrificed for style. Origin sliders feature:
Multi-point Locking: High-security hooks that lock directly into the jamb.
3-Star Diamond Cylinders: Proven to resist snapping, picking, and drilling.
Available in over 150 RAL colours, you can choose from popular Anthracite Grey to bespoke woodgrain finishes. You can even opt for dual colours (e.g., black outside to match your guttering, and white inside to match your decor). Like all Origin products, these doors come with an industry-leading 20-year guarantee.
Double or Triple Tracks: Choose how many panels you want to slide. Triple tracks allow two panels to slide behind a third, opening up two-thirds of your aperture.
Flush Thresholds: We can install the track recessed into your floor, creating a seamless, trip-free transition from your kitchen to your patio.
Hardware: From sleek integrated handles on the OS-20 to high-grade 500mm stainless steel bar handles on the OS-44 and OS-77
The OS29+ is a premium aluminium sliding door system defined by its ultra-slim 29mm interlocker (the vertical section where the doors meet). It is an evolution of the classic OS29, now featuring redesigned profiles that offer better thermal performance and a sleek "flush stacking" capability.
For most homeowners, the OS29+ is the "Goldilocks" of sliding doors:
The "Near-Invisible" Look: At just 29mm, the sightlines are thin enough to provide an almost uninterrupted view of the garden, making a room feel significantly larger and brighter without the massive price tag of fully structural bonded systems.
Flush Stacking Technology: When the doors are fully open, the panels sit neatly behind one another in a flush alignment. This creates a much cleaner, more symmetrical look compared to older sliding systems where panels would stagger.
Superior Energy Efficiency: Unlike many slimline sliders that struggle with insulation, the OS29+ can achieve U-values as low as 0.78 W/m²K (with triple glazing). Even with standard double glazing, it easily exceeds current UK Building Regulations, keeping your home warm and your bills down.
Security Without Bulk: Despite its slim profile, it is PAS 24 certified. It features a multi-point locking system with six points of engagement and a 3-star diamond cylinder, providing peace of mind that the "glass wall" is as secure as a solid door.
Unrivaled Customisation: With over 150 RAL colours available—and popular shades like Anthracite Grey and Jet Black on incredibly fast lead times—it fits any property style, from ultra-modern extensions to traditional renovations.
Bifolds vs. Sliding Doors: Which is Right for You?
While both systems use premium-grade aluminium and offer a 20-year guarantee, the way they transform your room is distinct. One offers a 100% opening, while the other offers a 100% view.
Choosing between Origin Bifold Doors and Origin Sliding Doors is one of the most common dilemmas for homeowners. Both products are engineered to the highest standards in the UK, but they offer very different ways of living.
Sliding DoorsBest for: Panoramic views and homes where floor space is at a premium.
If your home overlooks a beautiful garden or landscape, Origin Sliding Doors (like the OS-20 Artisan) act as a giant picture frame.
Minimal Sightlines: With meeting stiles as slim as 20mm, you get an almost uninterrupted wall of glass.
Year-Round Views: In the UK, doors are closed for most of the year. Sliding doors provide a better view during the winter months because there are fewer vertical frames blocking the light.
Bifold DoorsBest for: Entertaining and creating a true indoor-outdoor flow.
Origin Bifolds (like the ultra-slim OB-36+) are designed to disappear. When fully opened, the boundary between your kitchen and patio is entirely removed.
The Traffic Door Advantage: Most Origin bifold configurations allow for a "lead door." This functions like a standard back door, allowing you to let the dog out or take out the bins without unfolding the entire system.
Versatility: Bifolds can fold inwards or outwards and stack to the left, right, or both.
Perfect for Families: Origin’s unique finger-safe gaskets prevent small fingers from getting trapped in the hinges.
