Difference between OW-70 and OW-80
The main difference between OW-70 and OW-80 is the way that they look.
OW-70 offers the slimmest sightlines at just 65mm wide, ideal for those looking to maximise on natural light and views. OW-80 may not offer sightlines as slim as OW-70, however, it offers an internal flush casement, which OW-70 cannot provide.
Both OW-70 and OW-80 are manufactured using premium grade aluminium, are durable and low maintenance, and come with an industry-leading guarantee of up to 20 years.
Ultra-slim sightlines
Completely bespoke and made using premium grade aluminium – just like all Origin products – the OW-70 offers a slimline alternative guaranteed to modernise your property.
Achieving a sightlines of just 65mm, the Origin Slimline Window 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.
Built with security in mind
The OW-70 is crafted using premium grade aluminium to offer the same levels of strength, durability and high quality that Origin products are renowned for.

The lock itself is a stainless steel multi-point lock. Number of locking points vary depending on the size of the window, meaning security is not compromised no matter how big your window is.
