The premium Origin Window

Extremely low maintenance and energy efficient, the premium grade aluminium used for Origin Windows combines strength and robustness for an extremely strong yet lightweight structure - weighing 67% less than steel. The aluminium frames won’t flex, warp or corrode in variable weather conditions, making aluminium the solid choice for your windows.

Unlike timber or uPVC, aluminium windows such as OW-80 are so low maintenance that all they require is the occasional wipe with soapy water. Timber and uPVC windows can be problematic and costly in the long-term, as both materials are prone to contorting in varied weather conditions and require regular maintenance. Aluminium is reliable, robust and more environmentally friendly than these other materials, meaning aluminium windows could even add to the value of your property.

Why aluminium is the first choice for replacement windows

Internal and external flush casement window

OW-80 features an industry-unique internal and external flush casement, sitting perfectly in line with the frame to offer an elegant finish both inside and outside your home. Stunningly designed and expertly executed, it’s thanks to the high quality aluminium we use that we’re able to achieve this design, giving you less window and more natural light.

An industry-leading guarantee

OW-80 faces rigorous quality testing at each stage of the manufacturing process at our Buckinghamshire-based factory to ensure it’s up to scratch. It’s this in-house quality control, premium grade aluminium and exceptional craftsmanship that allows us to offer an industry-leading warranty of up to 20 years. And, unlike many of our competitors, our guarantee covers all hardware and components as well as the powder coating, giving you complete peace of mind that your window will last for many years to come.

Configuration options

As a totally bespoke window, the OW-80 can be made to fit almost any size and configuration. Here are some of the more popular configurations available with OW-80, which includes top hung, right hung, left hung, French windows and fixed frames:

Additionally, the hinges found on OW-80 are made of corrosion-resistant stainless steel and have been cycled tested to 50,000 cycles. Hinge guards feature patented anti-slip and lock technology as standard along the hinged side of the window. All window hardware is covered in our 20 year guarantee, giving you complete peace of mind that you, your family and your belongings will be safe and secure.

Lower energy bills

Lowering your energy bills

Combined with a polyamide thermal break within the aluminium profile, OW-80 not only meet thermal efficiency building regulations, it exceeds them. Our sophisticated design means that your home will be kept warm in winter and cool in summer, in turn helping to lower your energy bills.

Thermal performance

OW-80 is the only window on the market to offer sophisticated Aerogel technology, boosting energy efficiency to the highest possible A++ rating. Aerogel insulation is so powerful it’s used in spacecrafts and spacesuits, offering thermal efficiency that’s truly out of this world. Upgrading to Aerogel can increase the insulation of windows by up to 67%, achieving a U-Value of 0.8W/m2K with Origin’s OW-80 Window.
