Spain

Cortizo

Cortizo is Spain's largest aluminum systems house, founded in 1972 in Padron, Galicia, and now present in 30 countries with more than 80 aluminum and uPVC platforms. Three of them anchor the range I quote. The COR 70 Hidden Sash conceals the operable leaf behind the frame and pairs it with Arch Invisible - a handle built into the sash profile and operated from the side, so the window shows no hardware at all from the front. Hinges and drainage disappear with it. The COR Vision sliders run in the opposite direction: 20 mm central junctions, leaves to four meters, and mullion-free corners for openings where the frame is supposed to disappear. Millennium Plus Pivot completes the set with an oversized entrance door turning on an offset axis.
