Introducing theOrigin Window

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.

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

Ultra secure
Weather tight seals

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 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.

More colours than a rainbow

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.

Realistic Woodgrain finishes

The perfect way to coordinate with existing doors and windows - or simply to enjoy the modern benefits of aluminium with the traditional look of wood - our woodgrain finishes are high quality and realistic.

Unlike real wood, aluminium windows are low maintenance and won’t warp in varying weather conditions. Also, with more than 75% of all aluminium ever produced still in production today, aluminium is the environmentally friendly choice for your windows.

Made in Britain

We want you to feel safe and secure in your home, which is why we’ve taken every step to ensure that our windows satisfy and surpass current building regulations. This includes factors such as emergency exits, restricted opening and marine-based dwellings.

Extra ventilation can be added inside the sash through the installation of trickle vents, and side hung windows can be designed to serve as emergency exits that comply with British Building Regulations. Get more information on building regulations for windows.

Choose your handles

Rest assured - our handles have been given just as much attention to detail as every other component and are the perfect finishing touch to our elegantly designed windows.
