Turning the handle lifts the sash off its seals; turning it back lowers it onto them. We fabricate Cortizo profiles to the manufacturer's specification in our Dubai factory and install them ourselves.
Terraces, majlis and pool decks
4600 Plus is chosen for wide, heavy doors that are opened every day: from the living room to the garden, from a majlis to a courtyard, from a villa onto the pool. On up to four tracks the sashes stack behind each other, and the corner version opens two walls at once.
What Uw from 0.65 W/m²K and 22–65 mm glazing mean here
Uw from 0.65 W/m²K is the lowest starting value among the Cortizo sliding systems on our list: COR Vision Plus is published from 0.9 W/m²K and 4900 Sliding HI from 1.2 W/m²K. The glazing range of 22–65 mm takes a thick laminated solar-control unit for sun-facing glass that stays closed through the summer, or triple glazing where acoustics or the thermal calculation call for it. Lowered onto its seals, the sash stays tight against dust.
4600 Plus or COR Vision Plus
COR Vision Plus hides the frame, narrows the junction to 25 mm and goes up to 4000 × 4000 mm, with 400 kg manual or 700 kg motorised. 4600 Plus has a visible frame and an 80 mm sash, but a lower published Uw and a wider glazing range.
4600 Plus is the Cortizo door for wide terrace openings where insulation matters as much as the view.
