Completely bespoke and made using premium grade aluminium (like all Origin products) the OW-70 window offers a slimline aluminium window guaranteed to stand the test of time. 

OW70 has a slim sightline, ideal for taking in the most of your view. OW80 may have thicker sightlines but offers a casement which is flush both internally and externally a real thing of beauty. 

This slimmest window in the Origin family is available with a 20 year Origin guarantee as an internal flush casement. Available in both casement and fixed configurations this window is ideal for spaces where maximizing glass size and light is essential.


The OW80 features an industry leading unique internal and external flush casement, sitting perfectly in line with the frame. This window boasts extremely low maintenance and energy efficiency; combining strength and robustness for an extremely strong yet lightweight structure weighting 67% less than steel. 

The aluminium frames will not flex, warp or corrode. Unlike UPVC and timber these windows are also low maintenance. They only require a wipe down with soapy water to keep them sparkling. 

The key difference between the Origin Windows OW80 and the OW70 is the way they look. Both are manufactured from the same high grade aluminum, are durable, low maintenance and come with an industry leading guarantee.
