What Are Cortizo Cor Vision Sliding Doors?
Cortizo sliding doors are renowned for their slimline design, incorporating sleek lines and an ultra-slim 20mm mullion, providing an almost seamless transition between the interior and exterior of a property. Extruded in Spain by Cortizo the system company, Origin were one of the first to bring these doors to market, with what is now their OS-20 Artisan.
Over the years more and more aluminium manufacturers and trade suppliers are making Cortizo Cor Vision sliding doors and as we explain in this article, under all manner of brand names. What you will struggle to find is a Cortizo manufacturer manufacturing the entire UK Cortizo range, including windows, bifold doors and other products. Most focus mainly on the sliding doors.
The CVS 20 sliding door is made exclusively by one manufacturer who specialises only in Cortizo doors and windows and no other system. This expertise and the obvious benefits of a sole-system manufacturing facility has created what is available in the retail market as the CVS 20 – a re-engineered version of the standard Cortizo Cor Vision sliding door. CVS 20 has improved specifications, better functionality, vastly improved core components and features, some visible, others hidden. Overall, CVS 20 elevates a standard Cor-Vision into an altogether better product.
Cortizo CVS 20 Sliding Doors Design and Aesthetics
The design and aesthetics of Cortizo sliding doors are already impressive, otherwise these doors would not be as popular as they are, whether sold as Cortizo or rebranded.
The outer frames, head, cill and sliding panel profiles are all pleasingly slim, allowing for more glass and less visible aluminium. The 20mm mullion is of course, one of it’s best features, that looks impressive on a two panel large sliding door, but also just as good as a three panel. Our advice is to avoid four panel versions of these doors. as the meeting stile in the middle bulk up the sightlines considerably, on what is otherwise a slim sliding door.
Using a standard installation, without hiding the frame, the sightline at the frame sides is just 77mm. The head is 79mm assuming the trickle vent needed to comply with Building Regulations is also provided.
The handle on the Cortizo Cor-Vision is the instantly recognisable type, that also identifies all the other manufacturers, rebranding these doors.
Flush and unobtrusive, it operates the multipoint locking system as well as providing additional final locking, via the high-security key cylinder.
Cortizo Cor Vision sliding doors are characterised by their minimalist overall aesthetic, and promise refined sightlines, whether you go with a standard installation or by partially hiding the frame in the structure or behind the plaster. offering refined sightlines and larger glass surfaces that contribute to a more sophisticated overall appearance.
Where CVS 20 is better than the standard Cor-Vision Sliding Doors
Well made, professionally fitted by an experienced installer and correctly bonded, Cortizo Cor Vision sliding doors are an exceptional slider. The CVS 20 re-engineered versions offers three distinct additional features.
A flush stacking design
On a two or three-panel design, the CVS 20 sliding doors are available with a flush stacking design. There is only one other sliding door in the UK market with this fantastic feature. In the fully open position, other sliding doors two or three panel park in a staggered position.
The flush stacking design allows for all the panels to fully open and sit seamlessly together. the unique flush stacking design, which, when fully opened, provides a sleek appearance and maximizes the space for passage. This contrasts with the non-flush stacking design of standard Cortizo doors, offering an aesthetic and functional upgrade.
Stainless steel wheels on a stainless steel track
Many standard Cortizo sliding doors come with sliding door rollers made by Manufacturas Pabose a specialised Spanish manufacturer of ball and needle bearings which include sliding door rollers. These usually have plastic wheels running on the standard Cortizo track. Whilst these do work, and the sliding action of a Cor Vision is smooth and impressive, the CVS 20 comes with upgraded Pabose stainless steel rollers and track. This enhanced track and roller combination provides an even better and arguably longer lasting solution.
These improvements are not just superficial; the rollers and other internal components of the door have been designed for smoother sliding and a better sliding door experience for the user.
Improved weather protection on the track
The design of the Cortizo sliding door track divides opinion. It’s a recessed type and the inevitable consequence of this is that water will collect on the track when it rains. To a homeowner having spent many thousands on Cortizo Cor Vision sliding doors, this can be alarming and concerning.
Cortizo as a system company have engineered the door for it to be suitably machined and for water to drain away. Cortizo sliding doors machined for drainage, made and installed correctly should not leak. The reality is not every fabricator gets this right at the manufacturing stage and the installer often is not aware until its too late. It is also possible for water to find its way into the property in addition to unsightly water on the track. Let’s give this topic some context.
These are doors originally designed in Spain. In southern Europe sliding doors are usually protected in front by shutters and flyscreens. As well as this there is often a balcony or shading above. All these factors do a fantastic job of providing additional protection to the doors when it rains.
CVS 20 doors incorporate drainage at the bottom of the frame designed to expel water to the outside where it belongs. However, all of these doors must sit on a suitable cill or exterior drainage system. The issue is, whether enhance drainage comes as standard or it’s not addressed correctly. The integrated sub drain on the CVS 20 version does away with a well-known issue with water collecting on the Cortizo door track.
Enhanced sealing and protection
The CVS 20 variant of Cortizo Cor Vision sliding doors has another feature that can only been seen to be understood. So good is the sealing on the door set, that the best way to describe this, is that as the door panels pass each other on sliding, they create an air vacuum or air lock.
This is evident when on this particular door set, when deliberate and unnecessary force was applied to make the doors slide fast along the track. (not recommended with any door). Half-way through the forced push and sliding action, the doors slowed down altogether, on their own. This is not some soft-close or anti-slam feature. It is the weather seals on the outside of the door set being so good, that they create an air trap between the overlapping and opening panels.
A flush appearance on the inside of the doors
Whilst the Cortizo Cor Vision sliding doors benefit from the 20mm mullion, the thin nature of this means a deeper projection into the room. CVS20, depending on the size are available without the projecting mullion on the inside using an alternative glass specification.
The benefit is a door that looks flatter internally and looks the same viewed from any angle.
