Comparing OW-70 to OW-80
The key difference between OW-70 and OW-80 is the width of the window sightlines. Our OW-70 range offers the thinnest sightlines for more natural light and less window profile. However, the OW-80 range offers more configurations, large sizes and offers more customisation options.
Both window ranges offer a guarantee of up to 20 years and a range of RAL colours and popular colours available on a faster lead time.

High quality aluminium windows
Virtually maintenance-free and energy efficient, our premium grade aluminium combines strength and robustness with a lightweight structure - extremely strong yet weighs 67% less than steel. Unlike many other materials, Origin Windows won’t warp, flex or corrode in variable weather conditions for a reliable window that’s smooth to operate.
Built to last
Every Origin Window faces rigorous quality testing at each stage of the manufacturing process at our Buckinghamshire based factory.
By combining premium grade aluminium with precision engineering, exceptional craftsmanship and quality control, Origin is able to offer an industry-leading guarantee of up to 20 years on all window components. Enjoy contemporary aluminium windows and complete peace of mind with Origin Windows.
Sophisticated style, ultimate security
The OW-80 window range feature Yale’s renowned Encloser system, which offers the highest level of security by engaging cylindrical cams into the window keeps.
The OW-70 window range offers the Nemesis multipoint lock, which is fitted to accurately align with the keeps and the cams are manufactured to be finely adjusted if necessary.
All of our windows are both Secured By Design and PAS 24 certified. Our hinges are corrosion resistant and go through rigorous testing and feature a friction adjustment without metal-to-metal contact, ensuring minimum wear. Hinge guards, crimped frames and locking handles further improve impenetrability, making Origin Windows one of the most secure windows on the market.

With over 150 colours to choose from, you’re bound to find the right colour to suit you and your home. And, should you want different coloured windows indoors and outdoors, then you can opt for our dual colour option.
Finished with a durable, scratch-resistant powder coating, Origin Windows are smooth to the touch and low maintenance. Our powder coating is included in our guarantee of up to 20 years.
