Product Overview
The Cortizo COR 70 HO is an aluminium tilt and turn window that opens inward in two ways: tilted from the top for secure ventilation, or swung fully open for cleaning and maximum airflow. Thanks to its slim frames, from the outside, it reads more like a fixed pane than an opening window.
It suits modern homes where clean lines matter, replacement projects upgrading from uPVC or timber, and anywhere you want generous glazing without the visual clutter of traditional window hardware.
