especially useful on coloured frames

• No mismatch of foils on the extension when running alongside
each other

stock items

on the 84mm outerframe

The handle on the Cortizo Cor-Vision is the instantly recognisable type, that also identifies all the other manufacturers, rebranding these doors.
Flush and unobtrusive, it operates the multipoint locking system as well as providing additional final locking, via the high-security key cylinder.

The design and aesthetics of Cortizo sliding doors are already impressive. Otherwise, these doors would not be as popular as they are, whether sold as Cortizo or rebranded.
The outer frames, head, cill and sliding panel profiles are all slim, allowing for more glass and less visible aluminium. The 20mm mullion is, of course, one of its best features, that looks impressive on a two panel large sliding door, but is also just as good as a three panel.
