Engineered specifically for British weather resilience, thermal efficiency standards, and architectural demand for maximum daylighting.
Featuring minimal 20mm interlock sightlines and PA66 thermal breaks, engineered for modern London and Manchester residential developments.
Compliant with UK Building Regs Part Q. Multi-point steel locking mechanisms with anti-burglary laminated glass options.
Designed for cold northern UK climates, delivering extreme heat retention with Low-E soft coating and Argon gas filling.
Heavy-duty structural load capability tailored for luxury UK hotel upgrades, commercial towers, and coastal resort properties.
The United Kingdom fenestration market demands meticulous engineering to withstand harsh North Atlantic weather conditions while meeting rigorous statutory energy conservation and security standards.
UK Approved Document L mandates strict thermal performance limits for replacement windows and new builds. Our sliding window systems feature multi-chamber polyamide thermal breaks (PA66 GF25) paired with Low-E double or triple glazing, achieving thermal transmittance values as low as 0.8 W/m²K—exceeding current and prospective Future Homes Standard benchmarks.
Security is paramount in modern UK residential developments. Orion sliding windows integrate hardened steel multi-point gearboxes, anti-lift pins, concealed hinge blocks, and toughened/laminated security glass combinations. Rigorously tested against manual intrusion tactics, our systems provide peace of mind for property developers and homeowners alike.
From exposure to salt-laden coastal winds in Cornwall and Scotland to driving rain in the Midlands, our frames undergo salt spray testing up to 1,000 hours (ASTM B117 / EN ISO 9227). Advanced EPDM weather seals guarantee air permeability (Class 4), watertightness (Class E900), and wind load resistance (Class C5).
Modern UK architectural trends strongly favor minimalistic, invisible-frame designs that maximize natural light penetration. Orion offers custom architectural powder coating in any RAL shade—including popular UK colors like Anthracite Grey (RAL 7016), Jet Black (RAL 9005), and Agate Grey (RAL 7038)—with Qualicoat Class 2 weatherability approval.
Combining elite manufacturing scale, international compliance, and robust R&D capabilities to deliver unbeatable OEM/ODM value.

Versatile fenestration solutions designed to match diverse British architectural contexts—from heritage restoration to bold contemporary masterplans.
Ideal for open-plan kitchen extensions, rear patio openings, and multi-storey luxury dwellings in Surrey, Cotswolds, and Greater London. Pocket sliding variants allow panels to disappear into cavity walls completely.
Providing robust operation, floor-to-ceiling panoramic glass walls, and enhanced acoustic insulation for city hotels in Manchester, Edinburgh, and Birmingham where quiet indoor spaces are paramount.
Unmatched wholesale value, standardized profile suites, and rapid custom fabrications designed for local UK fabricators, window trade depots, and regional architectural ironmongers.
Staying ahead of market evolution with smart automation, low-carbon materials, and next-generation vacuum insulation.
Modern smart homes across the UK increasingly require motorized sliding windows synchronized with Building Management Systems (BMS), weather sensors, and mobile apps. Our motorization kits offer smooth magnetic levitation drive mechanisms with obstacle safety detection.
VIG technology achieves triple-glazed thermal insulation ($U \le 0.6 \text{ W/m}^2\text{K}$) within the slim profile width of single glazing. This enables ultra-thin frames ideal for UK conservation areas and modern low-carbon eco-homes.
To assist UK clients in achieving net-zero goals and BREEAM certification, Orion utilizes hydro-powered primary aluminium billets containing up to 75% recycled scrap content, reducing embodied carbon by over 60%.
