Product details
The concealed sash, considered.
View full size Evolution conceals the moving sash from the frontal view, changing the relationship between the glass and the surrounding frame. Its 25 mm central interlock and 62 mm lateral sightline create a distinct visual arrangement within the COR Vision family.
A dedicated rotating handle controls opening and closing. Rail, pocket and corner layouts are available within the system range, with glazing depth and sash weight checked for the chosen configuration.

Frame, opening & operation
Compare sliding systems.
Four Cortizo systems, with different frame details, sash limits and ways to open. Start with the view you want, then check the complete opening.
Published limits must be checked together. Width, height, glazed area, sash weight, glass, hardware and opening layout all constrain the final specification. These are individual system limits, not guaranteed combinations or whole-opening dimensions. COR Vision Plus is not a guaranteed 4000 × 4000 mm pane: its 14 m² glazed-area ceiling also applies.
