A closer comparison

Compare sliding doors.

Four Cortizo systems, with different frame details, sash limits and ways to open. Start with the view you want, then check the complete opening.

Discuss your 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.

From comparison to specification

Make it work for your opening.

Plan the opening

Send the full structural width and height, pane arrangement and the space available for stacking or pockets. Sash maxima do not describe the total width of a multi-panel opening.

Compare the installed detail

Review the central meeting section alongside the side frames, threshold, handles and floor junction. A slim interlock alone does not describe the whole opening.

Check the complete specification

Glass weight, wind loading, exposure, drainage and access affect the finished design. Thermal figures depend on the selected size and glazing, so compare calculations for your actual configuration.

Your project

Bring the opening into focus.

Share your plans, approximate opening sizes and the details that matter to you. We’ll work through the relevant systems and confirm the specification.
