Cortizo Cor-Vision EVOLUTION
Introducing Evolution from Cor-Line Systems Ltd — a premium aluminium sliding door system that combines slim sightlines, generous glass panels and triple glazing to create bright, inviting living spaces.
Whether you’re planning a contemporary extension, renovating your home or designing a new build, Evolution gives you the freedom to make glazing a defining feature. Its minimal appearance keeps the focus on your surroundings, bringing garden views into everyday life.
Designed to make more of your view
Evolution creates a virtually frameless appearance, with options to recess the outer frames and sashes into the surrounding structure. Carefully planned detailing allows the glazing to take centre stage, creating a clean finish around the opening.
From a kitchen overlooking the garden to a living room opening onto a terrace, the system helps create a natural connection between your indoor and outdoor spaces. Large glazed areas welcome daylight into your home while maintaining a sense of openness when the doors are closed.
Triple glazing for a comfortable home
Beautiful glazing should feel as good as it looks. Evolution incorporates 46mm triple glazing and thermally broken aluminium profiles to help reduce heat loss and maintain comfortable indoor temperatures.
The system offers a published U-value of 0.88 W/m²K, with the performance of your doors dependent on their size and specification. We’ll help you select the right arrangement for your project, balancing appearance, insulation and practical requirements.
Flexibility for your design
Every home is different, and Evolution offers a range of configurations to suit your opening and the way you want to use it.
Options include layouts with up to four tracks, pocket solutions that allow panels to slide into purpose-designed wall cavities, and 90-degree corner configurations. These choices give you greater freedom to plan access, furniture positions and the connection to your outdoor space.
Our team will work through the possibilities with you, considering panel sizes, opening directions, thresholds and drainage as part of the overall design.
Security and weather performance
Evolution is a PAS 24:2022 certified system, providing tested security performance alongside its minimal styling. We’ll confirm the appropriate certified specification for your chosen configuration.
The system also offers strong published weather-test results, including Class 4 air permeability, Class E900 water tightness and Class C5 wind resistance. These performance measures help inform the specification for your property and its exposure.
A finish that complements your home
Evolution is available with a textured powder-coated finish as standard and a wide choice of colours, allowing you to coordinate your doors with windows, exterior materials and interior finishes.
Whether you prefer a dark frame to define the opening or a softer shade that blends into the surrounding architecture, we can help you explore a finish that brings the design together.
Integrated trickle vent options can also be considered as part of your ventilation requirements.
Optional smart features
For added convenience, Evolution offers optional Nuki smart locking. Switchable privacy glass is also available, allowing you to change the glass from clear to obscured at the touch of a button.
We’ll talk you through the available options and compatibility with your proposed door specification, so you can choose the features that suit your home.
Your project, supported by Cor-Line Systems Ltd
Choosing the right sliding doors involves more than selecting a frame colour. Panel proportions, access, finished floor levels and installation details all contribute to the completed result.
At Cor-Line Systems Ltd, we’ll help you work through those decisions with clear advice and a quotation tailored to your plans. We offer both supply-only and professional installation options, whether you’re working with your own builder or would like us to carry out the fitting.

Floating Corner with Cor-Vision
Sliding Doors –Jet Black RAL 9005M
This project showcases a striking floating corner installation using our Cor-Vision sliding door system, finished in jet black RAL 9005M.
Cor-Line Systems Ltd measured, designed, and installed the doors, delivering a seamless result that exceeded expectations and earned us a 5-star review from a very happy customer. Our sister company, Empire Roofing and Building Services Ltd, completed the building and roofing work. The combination of expertise made this the perfect blend of skills, showing exactly what is possible when high-performance glazing meets precision construction.
The floating corner design removes the need for a fixed corner post, allowing the glass panels to meet cleanly and slide away to create a completely open corner. The effect is a modern, clean look that maximises natural light and provides uninterrupted views of the garden and surrounding landscape.
Key features of this installation:
-
Floating corner design – no obstructing posts, creating a seamless transition from indoors to outdoors.
-
Cor-Vision slimline system – ultra-slim sightlines that emphasise the glass, not the frame.
-
Jet black RAL 9005M finish – a sharp, modern aesthetic that contrasts perfectly with the tiled roof and soft landscaping.
-
Effortless operation – large panes that glide smoothly, opening up the space with minimal effort.
-
Indoor-outdoor living – when fully opened, the living area extends onto the patio, delivering a versatile entertainment and relaxation space.
