Evaluating OW-70 and OW-80 Origin Windows from Herts Glass

The Herts Glass Origin Window catalogue presents two exceptional systems – the OW-70 and the OW-80. Each of these systems is an epitome of superior design and impeccable finish. Their key distinguishing aspect is the dimension of the window sightlines.

With the OW-70 series, experience the slimmest sightlines that enhance natural light inflow and minimize window profile visibility. Conversely, the OW-80 series provides a broader array of configurations, accommodates larger sizes, and presents an extensive range of customization options. Explore the distinct features of each system below.
