Cortizo Slim Line Sliding Doors - Cor Vision
Welcome to our range of industry-leading Cortizo Sliding Doors, featuring the stunning Cor Vision slim line sliding systems. Designed for contemporary living, expansive views, and exceptional performance, Cortizo doors bring unrivalled elegance and functionality to residential and commercial spaces across the UK.

Why Choose Cortizo Sliding Doors?
Cortizo has become synonymous with high-performance aluminium sliding doors that blend modern aesthetics with engineering excellence. Whether you’re extending a living space, opening up a patio, or designing a striking commercial façade, Cortizo Sliding Doors deliver on both form and function. Their reputation for durability, thermal efficiency, and smooth operation makes them a top choice among architects, developers, and homeowners.
The difference between Cortizo Cor Vision 20 and Cor Vision 25 comes down to scale, strength, and glazing capability. Cor Vision 20 is designed for sleek residential applications where ultra-slim 20mm interlock sightlines deliver a minimalist aesthetic, supporting sash sizes up to 2500mm wide x 3000mm high and panel weights up to 320kg, with glazing up to 30mm thick. Cor Vision 25, on the other hand, is engineered for much larger architectural openings and heavier glass. With slightly wider 25mm sightlines, it supports significantly bigger panels up to 4000mm x 4000mm, accommodates glazing up to 56mm, and handles sash weights of up to 400kg manually or 700kg with motorisation. While both systems offer excellent thermal performance, weather resistance, and security, Cor Vision 25 is the superior choice for large-scale, high-spec projects where size, weight, and acoustic performance are critical.
