Overview
What makes the COR Vision
stand out.
COR Vision is the system that made Cortizo's name in minimal sliding. A 20 mm central junction where two leaves meet, a 37 mm sash, and an optional concealed closing detail that lets the leaf sit fully inside the frame - the result is a slider that reads as glass with a pencil line through it. The 116 mm two-track frame (182 mm for three tracks) takes double glazing to 30 mm and moves leaves up to 2.5 x 3 m and 320 kg. Single, double, and triple-leaf layouts are available, along with a mullion-free 90-degree corner where two glass edges meet with no post between them.

Key Highlights
- 20 mm central junction where two leaves meet
- 37 mm sash with an optional concealed closing detail
- Mullion-free 90-degree corner: glass to glass, no post
- Leaves to 2,500 x 3,000 mm and 320 kg
- Class 4 air tightness and C5 wind load despite the slim section
- Full RAL palette with dual-color and anodized options
Ideal For
Mild and temperate climates where double glazing is enough, courtyard and terrace openings, and projects that want the minimal-slider look without stepping into the top price tier.
Consider an Alternative When
If the openings are larger than about 8 feet wide, or the climate calls for triple glazing, move to the COR Vision Plus. If lift & slide operation and higher thermal performance matter more than the sightline, the Aliplast Ultraglide is the value pick.
