Unique, the multi-award-winning supplier of UPVC and aluminium windows, doors, and curtain walling, has extended its product range.
With immediate effect, the business will fabricate COR Vision aluminium sliding patio doors from CORTIZO – the vertically integrated Spanish manufacturer respected around the world for the premium quality and stunning aesthetics of its systems.
COR Vision patio doors offer an almost frameless appearance thanks to their ultra-slim profiles, which have sightlines measuring just 20mm.
This frame-free look is further enhanced by the fact that door rails can be fully incorporated into the floor, while top and lateral frames can be embedded into the walls surrounding the door aperture. COR Vision can also include 90-degree corners without the need for a mullion.

Other benefits include good acoustic insulation, high levels of security, and a U-value of 1.3 W/m²K. This means COR Vision complies with Approved Document Part L for use on existing properties.
COR Vision also offers impressive design flexibility. Doors can be created using 2, 3, 4, and 6 sashes, with single, double, or triple tracks, and to fit openings measuring up to 13.2 metres wide and 3 metres tall.
Commenting on the introduction of COR Vision, Mir Patel, Aluminium Operations Manager at Unique, said: “Unique has fabricated a number of CORTIZO products since November 2023, including CORTIZO casement windows, bifold doors, and the 4700 sliding door system.
“Since we introduced these lines, they’ve proved incredibly popular, and by extending our range with COR Vision, we’re looking to build on that. We’ll be able to offer customers an additional choice of patio door that combines stunning aesthetics with some equally attractive functional benefits.”
