Slimline Window (OW-70)
The Origin Slimline Window (OW-70) is our slimmest window yet, combining strength and sleek design to create the finest aluminium window available today.
The difference between OW-70 and OW-80
The primary distinction between the OW-70 and OW-80 is their appearance.
At only 65mm wide, the OW-70 has the slimmest sightlines, making it ideal for those who want to maximise natural light and views.
Although the OW-80 does not have as thin sightlines as the OW-70, it does have an internal flush casement, which the OW-70 does not have.
Both the OW-70 and OW-80 are made of premium grade aluminium, are long-lasting and low-maintenance, and come with an industry-leading 20-year warranty.
A window created specifically for you
And we don’t just say that. All of our orders are completely bespoke, from the size of your window to the colour of your handle, so you can design a window that’s perfect for your home. Every OW-70 comes with either an inline handle or a crank handle, both of which provide an elegant feel and finish – you choose.
Designed with safety in mind
The OW-70 is made of premium grade aluminium to provide the same levels of strength, durability, and high quality that Origin is known for.
Thermal efficiency exceeds current building regulations, is Secured By Design and PAS24 certified, and has also achieved resistance to racking and static torsion certificates after being tested to some of the highest standards.
The OW-70 may be small, but it is extremely powerful.
The lock is a stainless steel multi-point lock that is precisely aligned with the keeps. The number of locking points varies according to the size of the window, ensuring that security is not compromised regardless of the size of your window.
We are so confident in our design that we provide an industry-leading guarantee of up to 20 years in non-marine environments.
As a result, you can be confident that your Origin Windows will last for decades.
