About Cortizo Arch Invisible Tilt and Turn Windows
The Cortizo Arch Invisible is a slimline aluminium tilt and turn window with the handle built into the sash profile and the hinges concealed, so from outside it looks like a fixed pane. Cortizo presents it as the first tilt and turn window with an invisible handle. The visible sightline is just 66mm, panes can be up to 1300mm by 2400mm and carry glass up to 160kg, and the U-value goes as low as 0.8 W/m²K with good acoustic reduction. It suits contemporary homes where the window should read as glass rather than frame. We make it to measure and install across London and the South East.
