Cortizo Bifold Doors
A secure, energy efficient and visually appealing choice for homeowners.
Product Description
The Origin OW-70 Window System is a premium slimline aluminium window designed to maximise natural light and offer expansive views. Engineered with sleek, minimalist profiles, the OW-70 delivers a modern aesthetic that’s ideal for both contemporary homes and traditional restorations. Its ultra-slim sightlines (approximately 65 mm) create more glass and less frame, elevating visual appeal while blending seamlessly with a range of architectural styles. Crafted from high-grade aluminium and bespoke to your requirements — including size, shape and colour — the OW-70 makes a striking, high-performance window solution for any elevation.
