Origin Aluminium Windows

The world’s leading manufacturer of aluminium windows

The Origin Home is a collection of the finest quality products, manufactured in Great Britain by Origin.

An integral part of this is the Origin Casement Window - a range of stunningly designed and exceptionally finished aluminium windows.

Modernising the design of traditional 19th Century timber windows, Origin have created a highly durable and blissfully functional solution which is perfect for the 21st Century.

With unrivalled good looks, security and thermal performance, the Origin Window also offers the added benefits of being maintenance free and manufactured from premium grade aluminium for long-term reliability.



OW 80 - Internal and external flush casement window

Smart and clean in appearance, the sash sits neatly inside the window frame, creating an industry-first internal and external flush casement window.

With no overlapping frames, often synonymous with windows, the flush casement comes together to creare a truly timeless finish.

The clean finish of the Origin Window therefore provides unbeatable versatility that lends itself perfectly to any property type.

Aluminium's innate strenght allows for incomparably slim sightlines without compromising on security. With the edge of the frame as little as 50mm from glass, it means less window and more light can be achieved.


OW 70 - Slimline external flush casement

The OW - 70 is our slimmest window yet, combining strength with sleek design to create the finest aluminium window on the market yet.

Achieving a sightline of just 65mm, it is one of the slimmest windows available with a guarantee of up to 20 years. These ultra-slim sightlines mean less frame and more natural light, as well as better views.

Available as either a casement or fixed window, the OW-70 is ideal for spaces where maximising glass size and light is essential.

Tested to some of the highest standards, the thermal efficiency exceeds current building regulations; is PAS 24 certified.

The lock itself is a stainless steel multi-point lock, which is fitted to accurately align with the keeps, meaning security is not compromised no matter how big your window is.



Choose from a spectrum of colours from subtle to statement

The Origin Window can be manufactured in over 150 different RAL shades. From the subtle to slightly outrageous, you can guarantee there will be a colour to suit every home.

We also offer a dual colour option, so while the exterior frames can match the existing building style, the interior colour can match or contrast your internal decor.

Also available on this incredible delivery promise are the authenticdally styled woodgrain effects.

The Origin Window is finshed with a durable, scratch resistant powder coating, making it smooth to the touch and highly resilient to the elements.
