Our superior aluminium window collection from Origin showcases beautiful, elegant windows with both modern or traditional style options – perfect for any property style. With 150 RAL colours to choose from, combined with the finest premium grade aluminium, our Origin windows will complement every home, from contemporary new builds to period style cottages. Open up your living space to completely suit your needs and fill your home with natural light.
Origin offers two distinct aluminium window systems, each engineered for different requirements and architectural applications.
OW-70 Slimline – The slimmest profile in the Origin range with 65mm sightlines, designed for properties where maximum glass area and minimal frame visibility are priorities. Perfect for contemporary homes, extensions and anywhere you want to maximise natural light and views.
OW-80 Premium – A more substantial 91mm frame that accommodates larger window sizes, additional configurations and enhanced thermal performance. Ideal for exposed locations, period properties requiring extra weather resistance, or installations demanding the highest energy efficiency.
Both systems deliver Origin’s signature precision engineering, with flawless welds, colour-coded gaskets for a coordinated finish, and a choice of 150 RAL colours including dual-colour options for different interior and exterior shades.
Size Capabilities
These systems can handle impressively large windows—up to 4.8 metres wide and 4.8 metres high. Perfect for stunning floor-to-ceiling windows or expansive picture windows that bring the outdoors in.
Thermal Efficiency
The OW-70 achieves U-Values up to 1.2 W/m²K, while the OW-80 reaches an excellent 0.8 W/m²K with Aerogel insulation. Both systems keep your home warm in winter and comfortable in summer.
Security Certification
Both systems are PAS24:2016 certified and carry Secured by Design accreditation—the quality mark backed by the police.
Both the OW-70 and OW-80 feature external flush casements—the sash sits level with the frame rather than protruding, creating a clean, contemporary appearance that works beautifully in any architectural style.
The OW-80 takes this further as an industry first: it’s flush both externally and internally. From every angle, you see smooth, uninterrupted lines with just a subtle shadow gap where the sash meets the frame. This creates a genuinely distinctive look that sets your property apart.
The flush profile isn’t just about aesthetics. Without protruding lips or stepped edges, these windows are considerably easier to clean—rainwater runs off smoothly, and there are fewer surfaces where dirt can accumulate. A simple wipe down keeps them looking immaculate.
Whether you select the OW-70 with its external flush finish or the OW-80 with flush lines throughout, you’ll enjoy a refined, architectural appearance that enhances both period and contemporary properties.
