Origin Doors

The UK’s leading brand of aluminium windows…

Whether you’re looking for something beautiful, elegant, modern or traditional, there’s something for you in the Origin Window range – no matter what your style of property. From new builds to the unconventional, period style cottages or existing builds, you can open up your space in a way that completely suits your needs and fill your home with natural light.

Comparing the OW-70 and OW-80…

The Origin Window collection consists of two systems – the OW-70 and the OW-80. Both feature stunning design and an exceptional finish – the main difference is the width of the window sightlines. 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. See the key features below.
