Cortizo Cor Vision Plus – review and opinion by debesto
The Cor Vision Plus system appeared on the market a few years ago as an extension of the offer of Cortizo, the system provider from Spain. It is an extension of the technical solutions used in the Cor Vision sliding system. The Cor Vision Plus system differs from the “regular” Cor Vision in that:
- it is warmer (more energy-saving)
- a thicker glazing unit can be used
- you can create a window of much larger dimensions.

Parameters
Cor Vision Plus meets all the basic requirements that an investor interested in minimalist sliding windows may have. The constructors took care of the maximum lighting of the rooms while minimizing the visible aluminum profiles and parameters expected by the market.
Heat transfer coefficient
The best thermal parameter for the entire window that the system provider managed to achieve was Uw = 0.9 W / m2K. This is due to the fact that Cor Vision Plus allows the installation of glazing units up to 54 mm wide. The design of the Cortizo Cor Vision Plus system definitely meets the requirements of the market standards. However, it is worth mentioning that there are solutions available on the market that achieve better results.
Parameter list
The list of the most important parameters is as follows:
| Maximum sash weight (manual) | 400 kg |
| Maximum sash weight (automat) | 700 kg |
| Maximum construction height | 4000 mm |
| Maximum sash width | 4000 mm |
| Maximum thickness of the glazing unit | 54 mm |
| Design depth of the sash | 69 mm |
| Visible width of the center post | 25 mm |
| Heat transfer coefficient | Uw from 0,9 |
| Soundproofing | Rw 43dB |
| Watertightness – resistance class | 9A |
| Wind resistance – resistance class | C5 |
Frameless construction
Which construction schemes are available?Cor Vision Plus offers many variants of opening and closing. The system maker provided construction schemes with the use of 1, 2, 3, 4 or 6 sashes. In the case of manual opening – depending on the needs – they can be moved on one, two, three or even four rails. In total, there are 21 wing layout schemes.
Cor Vision Plus sliding windows can also be opened with an automatic drive. Then the structure can operate in a 2- or 3-track version
The width of the center post
The Cor Vision Plus’s center post is only 25 mm wide. It is one of the best results on the market ex aequo with the Aluprof MB-Skyline post. Right behind Cortizo is the Yawal Moreview system (27 mm). Only the Sky-Frame system has a post with a width of only 20 mm.
The fact that the post in Cortizo is more than 10 millimeters smaller than the posts in Schuco sliding windows (37 mm) or Reynears (35 mm) is impressive. However, it is worth remembering that such a small difference with such huge dimensions is in practice difficult to notice with the human eye.
Maximum glazing size
The maximum dimensions of a single leaf, confirmed by Cortizo technologists, are width – 4 meters and height – 4 meters. This means that it is possible to obtain a width of up to 8 meters in the most popular scheme A. The system designers also point out that the glazed area of the sash cannot exceed 14 m2.
Construction of the threshhold
The depth of the threshold slot
Due to the use of the roller system, Cor Vision Plus can boast a minimal cavity in the threshold of the frame. The depth is only 1.7 cm. The lower part of the jamb can also be completely covered.
Sliding system
In Cor Vision Plus – instead of trolleys placed in the sash – the system builder used rollers located in the jamb. The wings that move on them have a reinforced inox steel rail, which is to make them more delicate in sliding. To see how the roller system in Cor Vision Plus works, watch the video.
Drainage system
Cor Vision Plus has an aluminum threshold with integrated drainage. System drainage made of stainless steel allows for completely threshold-free structures without the risk of rainwater penetrating into the building interior.
Innovations and differentiators
Drive hidden in the frame
Cor Vision Plus has an optional electric drive that is completely hidden in the window frame. This solution, apart from the obvious aesthetic values, facilitates the dimensioning and subsequent installation of windows. The engine, automation and control are integrated with the frame. All you need to do is plug in the cable and the drive is ready to go.
Easy sash disassembly
The traditional method of assembly with a peripheral frame and sashes with a cut at a right angle, allows for easy removal of the sash in the event of glass breakage or damage to the profiles.
Design
Building without a threshold with a hidden frame
Cor Vision Plus allows you to hide the door jamb threshold under the floor. Thanks to this, the transition between two rooms or the exit to the patio is completely threshold-free.
All-glass corners
In the Cortizo system, it is possible to make a structure with the so-called open corner. This solution is characterized by the lack of a corner post after the sashes are pulled apart.
Sliding windows hidden in the wall (galandage)
The Cortizo Cor Vision Plus system allows you to create an increasingly popular variant, which is to hide the sash in the wall. The so-called galandage allows for maximum light of the passage, thanks to the fact that the window is hidden in a specially prepared wall recess.
Two-color aluminum windows
With Cor Vision Plus, architects can let their imagination run wild. Windows are available in any color from the RAL palette. Moreover, it is possible to design two-color finishes. There is an option of varnishing, anodizing and powder coating.
Summary
Cortizo Cor Vision Plus is a system that has been well adopted in the segment of frameless sliding windows. Its so-called “Childhood” errors are over and it can be considered a very popular solution today. According to the debesto.com ranking it is the cheapest of the leading solutions – and what is worth emphasizing – it is not very different than more expensive competition in terms of technical parameters or design possibilities.
