Origin Windows are completely bespoke and made with premium-grade aluminium.

Modern aluminium windows, designed to give the best options for style, durability and long-lasting performance.

The Origin Aluminium Window range consists of two options - the OW-70 and the OW-80. Both stunningly designed and exceptionally finished, the key difference between the two systems is the sightlines. This means the width of the frame that you see in your view.

Both are completely bespoke to your requirements as Origin’s flexible production process gives you the freedom to customise your window to perfectly complement your needs. What’s more, with uncompromising security features, your home will stay as safe as possible whichever option you choose.

Longest Guarantees.

Like all Origin products, the windows are guaranteed for up to 20-years, so you can relax knowing that your Origin windows will last for years to come.

Virtually maintenance-free and energy-efficient, the premium grade aluminium combines strength and robustness with a lightweight structure - extremely strong yet weighs 67% less than steel. Unlike many other materials, Origin Aluminium Windows won’t warp, flex or corrode in variable weather conditions for a reliable window that’s smooth to operate.

Origin Windows ow 70 slimline aluminium framesOW - 70 Casement Windows for the Slimmest Frames.

If you want to maximise natural light and take advantage of the view, then the slim frames of the OW-70 may be just what you're looking for.

With a sightline of just 65mm, Origin offers one of the slimmest frames available. Combined with a wealth of personal choices and up to 20 years guarantee the Origin OW-70 is unbeatable for style, durabilty and performance.

The OW-70 is available with two frame styles - square or chamfered.

For the more traditional look of flush frames, look further down the page at the Origin OW-80.

The Origin Aluminium Windows OW-70 casement window can feature left, right or top openers. Because everything Origin does is bespoke, they can manufacture your window in a configuration that works for your home.

This can include a combination of different openers and fixed frames, and thanks to an ultra-slim aluminium profile, you can be assured of the best view of the world outside your aluminium window.

The OW-70 aluminium 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.

Premium OW-8O Aluminium Windows.

The biggest difference between the OW-70 and the OW-80 is the styling. The frames are still slim on the OW-80 but slightly wider than the OW-70. This allows for the flush fit frame for home owners who want a slightly more traditional look.

The high quality aluminium used allows Origin to craft a flush casement both inside and out. Internal flush frames are a unique design feature that can only be found on Origin windows.

The OW-80 aluminium window range feature Yale’s renowned Encloser system, which offers the highest level of security by engaging cylindrical cams into the window keeps.

All of Origin's aluminium 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 Aluminium Windows one of the most secure windows on the market. 

As with all Origin windows, each window is made especially for you so can be designed exactly the way that you want them.

Expert Advice.

Our advisers will help you think about each room and it's function so that you can plan windows that you will love forever.

Aluminium windows are an investment for your home that you will want to enjoy for many years and if you decide to sell, your choice of windows could help you achieve a better asking price. Aluminium windows are high on the wish list for homeowners.

Comparing OW70 to OW-80.

The key difference between OW-70 and OW-80 Origin aluminium windows 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, larger sizes and more customisation options.

Both aluminium window ranges offer a guarantee of up to 20 years and a range of RAL colours with more popular colours available with a faster lead time.

Origin Windows - aluminium windows for bay windows

Origin Aluminium for Bay Windows.

Aluminium windows are just as suitable for bay and bow windows as any other window. If you have a large picture window in the middle, you'll appreciate the slimmer frames to make the most of the view.

The diffference between bay and bow windows is that a bay window is characterised by a large window in the middle and a bow window is made up of smalller, usually evenly spaced windows.

If you have a home that has standard windows and bays, you'll be able to match them up beautifully.

Traditionally, the large window in the centre is left as a fixed window but due to the strength of aluminium, you could maximise airflow by having the centre as a top hung window without spoiling your outlook.


French Windows.

Beautiful to look through and easy to use, we are thrilled to now offer the Origin French Aluminium Window.

Featuring the effortlessly elegant and entirely unique internal and external flush casement, the Origin French Aluminium Window contains a moving mullion – so when you open both the left and right windows, you have a fully open space with no frame through the centre - similar to a French door.

Cost of Aluminium Windows Compared to uPVC.

When compared to aluminium windows, uPVC windows come out on top in terms of cost and are an estimated 20% less than aluminium. You also have more variety for quality standards with uPVC. You can buy extremely cheap windows but they are rarely worth it in the long term. Stretching the budget a bit could prove well worth it when build quality and finish are taken into account regardless of which material you choose.

Double Glazed or Triple Glazed?

Most windows in the UK are double glazed. This is because with modern windows, you can exceed the guidelines and achieve a warm home without the additional expense of triple glazing. However, if you want the best possible energy efficiency, Aerogel technology combined with triple glazing will achieve U-Values of 0.9 W(2K), well below the 1.8 set by the government.
