ranking aluminum premium patio windows

What are we comparing?

Our ranking is based on the windows:

  • of dimensions: 3000 × 2200 mm
  • color: smooth RAL 7016/anthracite on both sides
  • 3-pane tempered glass on both sides 4 mm (Ug = 0.5)
  • with a black warm-edge spacer between the panes
  • in opening scheme A (one sliding sash, the other fixed)
  • with the narrowest possible center post

In our ranking of premium aluminum sliding patio windows, we evaluate the following profiles:

Cheapest large premium aluminum patio windows – price list 2023

In the latest installment of our ranking, the cheapest premium patio window is Cortizo Cor-Vision Plus

This irreplaceable profile has reigned supreme in our listings since 2021, and despite its attractive price, Cortizo Cor-Vision Plus is not inferior to other systems in terms of quality, as confirmed by its top position in the “Quality/Price” category later in our ranking.

Its specifications should satisfy even the most demanding customer, from large glazing, excellent thermal and acoustic insulation, ease of operation, to high quality workmanship or the possibility of installing an automatic drive – Cortizo Cor-Vision Plus has it all.

In addition, the Cor-Vision Plus profile allows the frames to be fully concealed around the perimeter, which is one of the factors that contribute to its aesthetic appearance.

What if you’re looking for an even more cost-effective solution?

If a potential customer’s budget is so limited that even the cheapest system, Cortizo Cor-Vision Plus, exceeds their financial capabilities, offer them up to 40% cheaper alternative in the form of aluminum lift-and-slide doors with a narrow mullion (47.5 mm) – Aluprof MB-77HS. It is also worth considering even less expensive PVC systems such as Aluplast Smart-Slide and Gealan Smoovio.

Premium aluminum patio windows of the highest quality

Best quality and great thermal performance? That’s the Cortizo Cor-Vision Plus – the winner of this category.

The Cortizo Cor-Vision Plus can feature a 54 mm glazing package that provide safety, acoustics and energy efficiency, and thanks to a roller sliding system and a hidden threshold, your customer will be able to walk freely onto the terrace without worrying about potential tripping.

When the budget of the project is higher, it is also worth paying attention to Aluprof MB-Skyline type R, which chases Cortizo Cor-Vision with its score.

Premium aluminum patio windows – the best quality/price ratio

Three times the Cortizo Cor-Vision Plus? Why not! In the quality/price category, the Cortizo system once again outperformed the competition.

The good old Cortizo Cor-Vision Plus has improved the maximum possible thickness of the glazing package, which is now 56 mm (2 mm more than in previous years). As we mentioned earlier, Cor-Vision Plus also offers excellent thermal performance, a hidden threshold, a thin center mullion, and a roller sliding system, all combined with a really attractive price.

Direct competition turns out to be the 193 EUR more expensive Yawal MOREVIEW, with a 60 mm glazing package and comparable parameters and features to Cor-Vision Plus.

Why does the hidden threshold and roller sliding system matter?

A hidden threshold, as the name implies, can be hidden under panels or tiles, but such a threshold is not only of aesthetic importance, but also functional – people with reduced mobility, the elderly, or children, can enjoy full freedom of movement.

Why is debesto leaning toward roller sliding systems? In our experience, trolley systems are simply easier to damage, which equals more frequent complaints.

Automatic sliding systems are clearly more expensive than those with manual opening, but if the customer has children, elderly or disabled people at home and is looking for modern solutions, automation may be the ideal choice. Based on the table, we can confidently say that the Cortizo Cor-Vision Plus is the most cost-effective solution.

Maximum sash weight in premium sliding windows

Sliding windows with manual drive

Why is the maximum sash weight an important parameter? Because the greater the permissible weight of the sash, the larger the dimensions of the structure and the larger the glass pane and the thicker the glazing unit can be.

For manual opening, debesto recommends sashes with a maximum weight of 300 kg. For the sake of safety and convenience of your customers, for heavier designs, we recommend an automatic drive.

Sliding windows with automatic drive

Large automatic sliding windows, in addition to a higher price, also have a slightly altered design, so that the allowable maximum weight of the sashes is higher. As our ranking shows, the greatest possibilities in this regard is the Yawal MOREVIEW system, in which the maximum sash weight can be as high as 1200 kg.

Additional categories – what else should you know?

Warmest premium aluminum patio windows

Leading the way in this category are: Reynaers Hi-Finity, Cortizo Cor-Vision Plus and Yawal MOREVIEW with U-Value of 0.14-0.15 (Uw=0.8-0.85).

Despite its huge size, aluminum sliding doors have excellent thermal insulation, U-Value of 0.14, which means that patio windows with this heat coefficient are classified as passive sliding systems.

The U-Value indicates how much heat escapes through the window – in practice, this translates into heating bills, and the lower the U-Value, the greater the savings.

Premium sliding windows with the narrowest center post

Modern sliding systems are characterized by a narrow center post. The narrowest post of only 25 mm is found in the Cortizo Cor-Vision Plus and Aluprof MB-Skyline type R systems.

Next in line is Yawal MOREVIEW with a width of 27 mm.

Why does the width of the center post matter?

The main reason is the aesthetics of the design, nowadays, customers expect as few visible frames as possible in a window – window joinery is supposed to be minimalist (as the name “frameless” suggests). Instead of splitting the view in two, a thinner center mullion allows for greater integration of exterior and interior space, which is particularly attractive for panoramic views.

Since modern sliding systems already manage to effectively hide window frames, the place where the sashes connect must also fit into the idea of minimalism. A narrow post is the ideal solution in this case.

Dear System Provider!

Is your system absent from the ranking? Do you think it has the potential for a higher placement?

Our rankings are created to assist in the expansion of our clients’ businesses. We reward profiles that give them the most hands-on benefits. That’s why, in addition to technical parameters, suppliers of the finished product are also important.

Recommend us a manufacturer that uses 100% of the capabilities of your system, sells it at an attractive price and provides substantive support, and we will be happy to update the data in the next edition of the ranking!

Ranking Methodology

The so-called hard data, that is, the below-mentioned parameters of finished products, go first:

  • maximum weight of a window sash without a drive
  • the width of the center post
  • U-Value coefficient
  • sliding systems

The debesto’s analysis department also decided to compare sliding windows in terms of automation capabilities. In addition to the parameters listed above, we awarded additional points for:

  • the possibility of using an automatic drive
  • the simplicity of the assembly of the electric motor
  • ease of processing
  • maximum weight of the sash with automatic drive

We also took into consideration:

  • quality of the aluminum system
  • system completeness (possible variants and compatibility with other systems)
  • the quality of the glass used
  • prefabricator evaluation
  • delivery times
  • the likelihood of a complaint
  • technical support at the sales stage and after-sales (including possible complaints)

How did we assess the reliability of the supplier? Our criteria included, for instance:

  • order processing time and timely completion
  • complaint handling and technical support at the sales and after-sales stage
  • time of preparing quotations

It is worth noting, however, that the ranking is by its nature subjective. This is also the case this time. Its result is not only a collection of facts, but also feelings and experiences of our company, debesto’s clients, prefabricators and system providers.

If, as a system provider, you see any irregularities in the description of your products, please let us know. We emphasize that it is the manufacturers who provide us with data for the compilation, thus they are responsible for this information about your profiles.
