Ranking of premium aluminum patio windows 2021. Comparison of large, frameless, sliding patio doors.
categoryPremium sliding windows at the lowest price category
Cortizo Cor-Vision Plus turned out to be the cheapest system in the latest edition of our ranking.
You can buy a large-size premium class sliding window with dimensions of 3000 x 2200 mm in Poland for approx. 4 175 EUR. Compared to the most expensive system in the list, you will pay over 3 times less! Interestingly, the low price of Cortizo does not mean lower quality than other systems, as evidenced by its position in the “The best value to money” category.
The Yawal Moreview system took 2nd place and the Aluprof MB-Skyline type R system was ranked 3rd. Yawal is 900 EUR cheaper than the Skyline type R. This is quite a big difference, so when choosing a particular system, it is worth taking into account the other parameters and matching them to the customer’s needs.
Your potential customer has such a tight budget that even the cheapest Moreview on the list is beyond their reach? Offer him an alternative, even 40% cheaper, in the form of an aluminum lift and slide door with a narrow post (47 mm) – HS Yawal DP 180. Or really cheap PVC systems: Aluplast Smart-Slide and Gealan Smoovio.
categoryPremium quality sliding windows category
Sliding windows characterised by the best quality in the ranking of debesto.com are Yawal Moreview.
Moreview scored maximum points for each parameter we assessed for the comparison of frameless sliding systems. The great quality of sliding doors is the satisfaction of your customers and for you a guarantee that you will not waste time on warranty repairs, replacement of elements and frequent service. High quality does not have to go hand in hand with a high price. Moreview is a great example of this. In Yawal Moreview, the widest glazing unit can be used in the entire set (60 mm), which ensures safety, great acoustics and energy efficiency. A roller sliding system and a low threshold will provide your client an access to the patio without any barriers.
Aluprof MB-Skyline type R (second place in the “Highest quality” category) using rollers instead of trolleys in the threshold eliminated the biggest pain of its older brother Aluprof Skyline, for which we awarded 2 points. Cortizo Cor-Vision Plus also has a roller drive system and excellent thermal parameters – that’s why, it received the same number of points.
Schuco Panorama ASS 77 PD is a premium product from a leading supplier of aluminum systems in the world. The reputation of the brand will undoubtedly be an argument that can convince your customers of Schuco’s offer. The downside is, unfortunately, the width of the center post, which is as much as 37 mm, which is one of the weakest results in our sliding window comparison. In times when modern architecture expects the largest possible glazing and the smallest possible frames, such a large width of the post may be a disadvantage in the eyes of customers. You will get quality comparable to the competition by paying an incomparably higher price.
categoryPremium sliding windows category - the best value for money
The product selection in the quality / price category was a matter of course. Cortizo Cor-Vision Plus won in the price category, showed the best quality and thus also won the competition for the optimal choice.
Cortizo improved the maximum possible thickness of the glazing unit, which is now 56 mm (2 mm more than before). It also offers excellent thermal parameters – the Uw coefficient for the configuration 1 active sash + fix is 0.8. Its reasonable price helped it climb to the top of the list.
Second choice is Yawal Moreview. The maximum sash weight of 400 kg, the width of the central post 27 mm, the thickness of the glazing unit 60 mm and Uw = 0.85 enable the construction of large and, at the same time, stable sliding windows and doors, while maintaining the suitable standards.
Aluprof MB-Skyline type R remains on the podium, which presents itself very well in terms of quality and received the maximum number of points for most of the parameters. Once again, we congratulate Aluprof on correcting the errors and resigning from the deep threshold in favor of sliding rollers. As a result, type R ranks better than its predecessor.
categoryBest value for money category - Premium sliding windows with automatic drive
The winner of the premium sliding windows with a drive is undoubtedly Cortizo Cor-Vison with a score of 19.38 points.
In the table on windows with automatic drive, pay attention to the “quality / price” category, which will help you choose the most optimal product, in which the quality will not be determined by the price. In this case, Cortizo took the lead and Yawal finished second with 16.68. Why is Cor-Vision ranked first among auto-drive systems? The decisive factor was the simplicity of the drive assembly, its connection and the final processing, for which he was awarded the maximum number of points. The automatic system is hidden in a dedicated frame, which makes it easy to process and assemble. Aluprof Skyline Type R took 3rd place, which could be seen on the podium in previous categories.

The best premium sliding windows with automatic drive (quality / price)
Patio windows, which we have collected and compared for the purposes of the ranking of debesto.com sliding systems, are standardly offered in a version with a manual drive. The system providers also offer versions with automatic drives, which are presented in the table below. Check which solution will be the most attractive for your customers who want to have solutions for intelligent houses. Comfort costs money, which is why sliding systems with an automatic drive are more expensive than their counterparts with manual opening. However, if your client wants modern solutions, and there are children, elderly or disabled people at home, automation may be the perfect solution. When he decides to use an automatic drive, opening and closing large and heavy patio windows will not be a problem for any of the household members. Based on the table, we can confidently conclude that the most cost-effective solution for patio windows equipped with automation is Cortizo Cor-Vision Plus. In our opinion, the biggest challenge for system providers to make premium electric sliding windows which are going to get a big popularity is to reduce the price of the drive. We believe that whoever wins this race will gain a huge competitive advantage!

Maximum weight of the sash in premium sliding windows
Sliding windows with manual drive
Sliding systems with the highest permissible sash weight (500 kg) are: Aluprof MB-Skyline and Skyline Type R, SAPA Artline and Schuco Panorama 77 PD. In other sliding windows, the maximum sash weight is 400 kg. The exception is the large-size Reynaers Hi-Finity profile, of which the permissible sash weight is only 300 kg. Why is the maximum weight of the sash an important parameter? Because the greater the permissible weight of the sash, the larger the dimensions of the structure, a larger pane and a thicker glazing unit is possible to do. In contemporary architecture where “size matters” this is crucial. It does not change the fact that in this case we agree with Reynaers, which limited the maximum weight of the sash. In the case of manual opening, debesto.com also recommends sashes weighing up to 300 kg. For the safety and convenience of your customers, we recommend an automatic drive for heavier structures.
Sliding windows with an automatic drive
Large automatic sliding windows, apart from the higher price, usually have a slightly modified structure, so the maximum permissible weight of the sashes is higher. As our ranking shows, the Reynaers Hi-Finity system has the greatest possibilities in this regard, in which the maximum weight of the sash can be as much as 750 kg. Cortizo Cor-Vision Plus and Yawal Moreview were just behind the first system mentioned above, with a slightly smaller capacity (700 kg). All these systems received 2 points for the weight of the sash on a scale of 0-2 points.
The maximum weight of the sashes in other systems is 500 kg. for which we awarded 1 point each.
Premium sliding windows with the narrowest post
Modern sliding systems are characterized by a narrow central post. The narrowest post, only 25 mm, has the Cortizo Cor-Vision Plus, Aluprof MB-Skyline and Aluprof MB-Skyline type R systems. Next up is the Yawal Moreview with a post width of 27mm. The four systems mentioned here received 2 points. for this parameter. Customers currently expect as few frames in the window as possible – the window joinery is to be minimalist and to cover the view outside the window as little as possible. Since in modern sliding systems it is already possible to effectively hide window frames, the place where the sashes connect must also fit in with the idea of minimalism. A narrow post is the perfect solution in this case.
Thickness of the glazing unit in premium sliding windows
The thickest glazing unit can be made on the Yawal Moreview, Schuco Panorama ASS 77 PD systems and in both versions of the Aluprof Skyline system. These structures allow for the placement of glazing units with a thickness of up to 60 mm. Maximum glazing at this level guarantees the construction of the most safe, soundproof and energy-efficient structures. Panoramic windows are 90 percent made of glass, therefore, in the case of such large glazing, the glazing unit is important because it should provide the best parameters in terms of statics, acoustics and heat. In this case, the thermal insulation of the entire structure depends on the pane. Currently, pane manufacturers offer very modern solutions, thanks to which we can increase the amount of light transmitted or improve noise protection.
The warmest premium sliding windows
One of the parameters of the best sliding systems is thermals. In this category, the following are in the lead: Cortizo Cor-Vision Plus, Yawal Moreview, Schuco Panorama ASS 77 PD and Reynaers Hi-Finity, which are characterized by the best Uw = 0.8-0.85 Despite its huge size, aluminum sliding doors are characterized by excellent thermal insulation, Uw = 0.8 means that patio windows with such a heat coefficient are passive sliding systems. The Uw parameter is extremely important for all windows, regardless of what material they are made of and what dimensions they have. The Uw coefficient shows how much heat escapes through the window. In practice, this translates into the amount of heating bills. The lower the Uw value, the greater the savings on heating! See the graphic below to see how much you can save by investing in energy-efficient windows:
