COR Vision & COR Vision Plus Sliding Systems
The COR Vision and COR Vision Plus systems are Cortizo’s flagship sliding solutions, designed for maximum transparency and panoramic views. With visible sections as slim as 20 mm, these systems achieve up to 94% glass surface, ideal for luxury homes that demand a seamless connection between indoor and outdoor spaces.
Millennium Plus Doors
The Millennium Plus system is designed for main entrances and high-traffic areas where performance, design, and durability must align. Engineered for large dimensions and enhanced thermal efficiency, this system offers robust architectural lines and exceptional mechanical resistance.
Thermal Break Curtain Walls
Cortizo’s curtain wall systems are designed for multi-floor glass walls, offering exceptional transparency with structural strength. Thanks to their high thermal break capacity, they meet today’s energy efficiency standards while allowing architects to realise bold, modern façade designs.
COR 70 Hidden Sash Windows
The COR 70 Hidden Sash system allows for completely flush glazing, where the opening sash is concealed behind the frame — achieving a fixed-glass look even in operable windows. This high-performance system offers exceptional thermal and acoustic insulation while maintaining a sleek and contemporary aesthetic.
Bi-Fold and Lift & Slide Glazing
Cortizo’s bi-fold and lift-and-slide systems provide maximum versatility for clients seeking to open up living spaces with minimal effort. These large-format openings are engineered for thermal performance, tight weather seals, and quiet, fluid movement even with oversized panels.
Fixed Glazing & Structural Glass Walls
For the ultimate minimalist aesthetic, fixed glazing systems allow for large-scale glass installations with minimal visible structure. These units can be silicone joined or structurally bonded, offering clean lines and dramatic natural light while maintaining thermal integrity.
Why Work With a Dedicated Cortizo Installer?

This ensures:
✅ No compromises in performance

We collaborate closely with design professionals during RIBA and LSF stages to integrate Cortizo glazing early into architectural plans.
We provide:
-
