Cortizo COR Vision

Cortizo COR Vision is a minimal, thermally broken sliding system with a narrow central junction and a frame that can be concealed around the perimeter, on one to three tracks. In UAE villas and apartments it suits living rooms and terraces with a view: the junction is 20 mm, sashes reach 2500 × 3000 mm and 320 kg, and Uw is published from 1.3 W/m²K.

Technical data

Minimal thermally broken sliding system with a narrow central junction and a frame that can be concealed around the perimeter; one to three tracks.

Values are the manufacturer's published figures for the series; the actual value depends on the configuration — glass, size and hardware. Which series fits your opening is settled at the free survey.

The idea is to keep as little aluminium as possible between the room and the view. We fabricate Cortizo profiles to the manufacturer's specification in our Dubai factory and install them ourselves.

Views from living rooms and terraces

COR Vision is chosen for the room where the glass is the wall: a living room facing the sea or the golf course, a bedroom opening onto a pool. With the frame hidden in the floor, walls and ceiling, the visible line is the 20 mm junction where two sashes meet. Pocket and corner versions let the glass slide into a wall or turn a corner without a post.

What its figures mean in UAE sun

The glazing range is narrow, 26–30 mm, which fits a double-glazed unit with a solar-control coating. That is what a sun-facing glass wall needs first, but it leaves no room for thick laminated acoustic glass or triple glazing. Uw is published from 1.3 W/m²K.

A hidden frame also hides the track. The drained sill and access for cleaning the running gear are planned before the floor is finished, because sand in the channel is what wears a slider.

COR Vision next to COR Vision Plus and 4900 Sliding HI

COR Vision Plus is the larger version: sashes up to 4000 × 4000 mm, 400 kg manual or 700 kg motorised, a 25 mm junction, glazing of 36–56 mm and Uw from 0.9 W/m²K. 4900 Sliding HI has a visible 35 mm junction and takes glazing of 24–36 mm. COR Vision sits in between, with the narrowest junction of the three.

COR Vision suits large sliding glass where the view matters more than a thick glass build-up.

The honest downside

When COR Vision is the wrong slider

The 26–30 mm glazing range is the main limit. For a bedroom over a busy road that needs thick laminated acoustic glass, or a project where the thermal calculation calls for triple glazing, COR Vision Plus with 36–56 mm glazing and Uw from 0.9 W/m²K gives more room.

The concealed frame is built into the structure, so it suits new builds and full renovations. Replacing an existing apartment slider with COR Vision means opening the floor and the reveals; where that is not possible, 4900 Sliding HI fits into a normal opening.

Consider instead Cortizo COR Vision Plus

Frequently asked questions

Only if the floor, the reveals and the ceiling around the opening can be opened up, because the frame sits inside them. At the survey the engineer checks what is behind the finishes and tells you whether a hidden frame is realistic.

Units from 26 to 30 mm thick: in practice a double-glazed unit with a solar-control coating, with laminated panes where safety requires them. For thicker acoustic or triple glazing we move to COR Vision Plus.
