Product Overview
The Cortizo 4700 is an aluminium sliding door with a 47mm central interlock – narrow enough for clean modern aesthetics, substantial enough to handle large panels without complicated engineering.
It’s available in inline (standard slide) or lift-and-slide configurations, with the latter using a lifting mechanism to reduce friction on heavier doors.

Design and Configuration Options
The Cortizo 4700 can be specified with 2, 3, 4, or 6 panels. Two-panel configurations use double track systems with frame depths of 115-120mm. Three or more panels require triple track systems with 185mm frames, supporting wider openings up to around 6.4m.
Both inline and lift-and-slide operation are available. Inline sliding is the standard mechanism—panels glide along stainless steel rails. Lift-and-slide adds a mechanism that raises the door fractionally when you turn the handle, reducing friction against the track. This makes heavier or taller doors easier to operate and is worth considering for doors over 2.5m high or those using triple glazing.
Available in RAL colours including dual colour specifications. Multi-point locking systems and appropriate glazing achieve PAS 24 security certification.
