Unique has extended its product range to include the COR Vision aluminium sliding patio doors from Cortizo.

COR Vision patio doors are said to offer an almost frameless appearance thanks to 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 whilst top and lateral frames can be embedded into the walls surrounding the door aperture. COR Vision can also include 90° 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 13.2m wide and 3m tall.

Mir Patel, aluminium operations manager at Unique, said: “Unique has fabricated a number of Cortizo products since November 2023 including casement windows, bi-fold 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.”
