Available in both OW-70 Slimline and OW-80 Premium ranges, the Origin Casement Window combines traditional design, advanced manufacturing
and versatile premium grade aluminium for high levels of security and thermal efficiency to complement any type of build.
OW-80 Casement Window
For a truly unique window offering, an industry-first internal and external flush casement, the OW-80 Casement Window will not disappoint.
Completely bespoke, OW-80 casement windows can be manufactured up to 7sqm in over 150 RAL colours to suit your preference. Colour-coded gaskets and handles allow you to add personality to your windows if you wish.
OW-70 Casement Window
Equally sleek and contemporary, the OW-70 Casement Window may not offer as many customisation options as OW-80, however, it does offer ultra slim sightlines of just 65mm. Able to accommodate sizes of up to 4.8sqm, the OW-70 provides a modern finish for any home.
Made from the same premium grade aluminium as all Origin products, OW-70 offers the same level of security as OW-80 and comes with the same industry-leading guarantee of up to 20 years.
OW-80 vs OW-70 Casement Windows
Both OW-70 and OW-80 casement windows offer a guarantee of up to 20 years, a contemporary look and exceptional levels of strength and security. However, there are some key differences between the two window ranges, show in the table below.

Thermally efficient
Origin Casement Windows can be specified to accommodate double or triple glazing, and thanks to a sophisticated polyamide thermal break that's built into the frame, both the OW-70 and OW-80 prevent heat transfer from the inside to outside and vice versa, ensuring they both comfortably exceed building regulations.
OW-80 windows can go the extra mile to achieve a U-Value as low as 0.9, when using sophisticated Aerogel technology - the same material that's used in space suits and space shuttles.
Our dedication to thermal efficiency means you’ll not only be able to enjoy a warm home in winter and a cool home in summer, but it means that you could even save money on your energy bills.
Highly secure
Every OW-80 Origin Casement Window is installed with Yale's renowned Encloser Locking system, and for the OW-70, it uses the Nemesis locking system, and both offer the highest level of security. The locks work by engaging cylindrical cams into the window keeps, and as a result of the ultra-secure design and manufacture, both systems are PAS 24:2016 certified and police preferred Secured By Design accredited, giving you complete peace of mind that your home is secure.
Each window can also be built with the highest grade stainless steel hinges, capable of carrying exceptionally heavy loads. Hinge guards, locking handles and crimped frames work together to further improve impenetrability of our windows, making the Origin Window collection two of the most secure on the market today.
