Introducing Our Windows

The Slimline OW-70 Window

Slimmer Profile to Help Make the Most of Your Views

Perfect for spaces where maximising the levels of natural light and making the most of the views is important, the Origin Slimline Window achieves sightlines of just 65mm making it one of the slimmest windows on the market. Despite this, there has been no compromise on the premium quality of the profile, with only prime billets of aluminium being used to ensure durability and functionality.

Available with Origin’s industry-leading 20yr guarantee, the OW-70 Window is available on a 4 week lead time when ordering in one of Anthracite Grey (RAL 7016M) or Hipca White (9910G). The OW-70 comes as either a casement window or fixed frame, for other window types such as gables or bays, please see our OW-80 Window.

The Premium OW-80 Window

Industry-First Internal and External Flush Casement

The Premium OW-80 Window comes with both an internal and external flush casement, meaning there is no step between the profile and the frame as with most windows on the market.  Available in more configurations than the Slimline Window, the OW-80 is versatile and bespoke to your requirements. Whether it is a bay, fixed, gable or casement window, the OW-80 can meet your needs. Available in over 150+ RAL colours, with 10 of Origin’s most popular being available on their ‘Your Lead Time, Not Ours’ promise – meaning you specify the timeline, not us.

The OW-80 is PAS 24 certified and features a Secured by Design-approved locking system. It has been cycle-tested to 50,000 cycles ensuring it stands the test of time.
