Origin OW-70 Slimline Window
The Origin OW-70 Slimline Window is the slimmest window in the Origin range, designed for homes where maximizing natural light and views is key.
With sightlines of just 65mm, this window features a sleek and elegant design, perfect for modernizing any property. Crafted from premium grade aluminium, it offers exceptional durability and strength, without compromising on style.
Available in casement or fixed frame options, the OW-70 provides the ideal balance between aesthetics and security, backed by a guarantee of up to 20 years.
Slimline Design for Maximum Light
The Origin OW-70 Slimline Window is designed to maximise natural light and offer uninterrupted views. With ultra-slim sightlines of just 65mm, these windows feature more glass and less frame, making them perfect for brightening any room.
Their sleek design adds a modern touch to both new builds and renovations, enhancing the overall aesthetic of your home.
Uncompromised Security
The OW-70 is built with premium-grade aluminium, ensuring exceptional strength and durability, qualities for which Origin products are known.
Despite its slim profile, the OW-70 is incredibly robust, holding PAS 24 certification for resistance to racking and static torsion.
The window is equipped with a stainless steel multi-point locking system, with the number of locking points varying based on window size, ensuring optimal security for any configuration, no matter the dimensions.
Difference between OW-70 and OW-80
The key difference between the OW-70 and OW-80 lies in their design. The OW-70 boasts ultra-slim sightlines of just 65mm, ideal for maximizing natural light and views.
While the OW-80 has slightly wider sightlines, it offers an internal flush casement not available with the OW-70.
Both models are crafted from premium-grade aluminium, ensuring durability, low maintenance, and come with an industry-leading 20-year guarantee.
