category Sliding systems at the lowest price

All windows in the ranking of sliding systems are at least good in terms of quality. By choosing even the cheapest sliding windows, you can be sure that they will be used for many years. Cortizo Cor-Vision plus turned out to be the cheapest system at the moment.

The price at which Cortizo Cor-Vision plus frameless windows rank first is the price for a system with manual drive. There is an option to choose these sliding windows with automatic drive, but with this, the price gets higher.

The Schuco Panorama ASE 67 PD and Yawal Moreview systems are sequentially in 2nd and 3rd place. The low price of Schuco may be due to the fact that it is a narrower profile than the others, it is distinguished by the weakest result of Uw = 1.2 and a glazing thickness of 49 mm.

The better choice will be the cheaper and much better Cortizo Cor-Vision plus profile, or the slightly more expensive, but the best in terms of quality, Yawal Moreview.

Yawal’s Panoramic Moreview system takes the top positions in the next categories, which is proof of its great quality and price.

category The highest quality sliding systems category

Yawal Moreview, Cortizo Cor-Vision plus, Schuco Panorama ASS 77 PD are characterized by the best quality in the ranking of sliding systems by

Moreview was given the maximum score for each parameter that we rated for the comparison of frameless sliding systems. Great quality will allow your customers to enjoy the panoramic sliding system for many years, and you will not waste time on repairs, services or replacement of elements.

The parameters of Yawal Moreview will allow you to obtain the best energy and acoustic properties. In the final choice, your customer may not be convinced of the Moreview system due to the lack of an automatic drive.

Cortizo Cor-Vision plus is a sliding system with almost invisible frames, dedicated to large glazing. Cortizo is a Spanish giant of aluminum joinery, which is conquering European markets with its high-quality products. Compared to Yawal panoramic windows, Cor-Vision is weaker due to the Uw = 1.0 parameter and the thickness of the pane packet, which is 54 mm.

Schuco Panorama ASS 77 PD is a premium product from the largest aluminum system supplier in the world. Your customer can be convinced by the reputation of this brand. The downside is the width of the center post, which is 37 mm and this is one of the weakest results in the sliding window comparison.

category Best value for money category

In the quality / price category, you will find large-size sliding systems that are the most profitable from the point of view of the customer and your company. This category will help you choose the optimal product for your client.

In the comparison of sliding systems, the best in this category was Yawal Moreview, which received the maximum number of points for quality from us, and its reasonable price helped him win the first place.

The maximum sash weight of 400 kg, the 27 mm width of the central post, the 60 mm thickness of the pane packet, and Uw = 0.8 allow the construction of large and stable sliding windows and doors while maintaining all the necessary standards.

The only downside of Yawal Moreview windows is the lack of a system with an automatic drive. The 2nd and 3rd place systems have this – Cortizo Cor-Vision plus and Schuco Panorama ASS 77 PD.

In the case of Cortizo, note the slightly weaker Uw = 1.0 and the thickness of the pane packet, which is 54 mm. On the other hand, Schuco Panorama 77 has one of the worst results in terms of the width of the central post. After consultation with the client and checking his priorities, you will know which sliding system to choose.

The best sliding systems with an automatic drive in terms of quality and price

The sliding systems that we have collected and compared for the purposes of the sliding systems ranking are in the version with manual drive. The windows that are possible to be made in the version with an electric drive are presented in the table below. We hope this will help you to choose sliding windows for your client.

Yawal Moreview and Schuco Panorama ASE 67 PD panoramic sliding doors are systems with which making an automatic drive is not possible at the moment. Other profiles have such possibility, but it is associated with a much higher price.

Convenience has to be paid for, and sliding systems with the automatic drive are an example of this. Does your client want a comfortable solution? Has he any children at home, elderly or disabled people? By choosing an electric mechanism, anyone can easily open and close the door without putting in any effort.

Based on the table, we can confidently conclude that the most profitable solution is Cortizo Cor-Vision plus. The price is not the lowest among the compared, but the quality helped to rise to the podium.

In other places, we have the SAPA Artline system, the price of which is the lowest, but the quality may raise slight doubts, especially among people for whom it plays an important role. Schuco Panorama 77 in 3rd place and Reynaers Hi-Finity in 4th place do not differ much in terms of quality / price.

Cortizo Cor-Vision Plus
10 2 700 14 25 390 5,51
Schuco Panorama ASS 77 PD

Maximum sash weight in sliding systems

The systems with the greatest weight of the sash are Schuco Panorama 77 and SAPA Artline – 500 kg. In other sliding systems, the weight is 400 kg. The exception is Reynaers Hi-Finity, whose weight is the lowest –  300 kg.

The weight is so important that the heavier the sash, the greater the dimension possibilities, the thicker the pane packet, the larger glazing, and the optically larger space inside. That is why, we awarded points for this parameter, which were taken into account when calculating the quality of window and door systems.

Sliding systems with the narrowest post

Sliding systems are characterized by a narrow central post. The narrowest post has the Cortizo Cor Vision Plus system and it is 25 mm, followed by the Yawal Moreview – 27 mm.

The narrow post looks extremely aesthetic and minimalistic. Large glazings let the maximum amount of light into the room, provide a panoramic view of the image outside of the window, and at the same time minimize visible thermal cross sections.

The thickness of the pane packet in sliding systems

The thickest glazing unit can be made using the Yawal Moreview and Schuco Panorama ASS 77 PD systems.

The Yawal and Schuco constructions allow the placement of pane packets up to 60 mm. Maximum glazing at this level guarantees the best acoustic and thermal properties.

Panoramic windows consist in 90% of glass, therefore in the case of such large glazing, it is important to install several panes with the best thermal parameters. In addition to high-quality glass, it is worth filling the space between the panes with argon or krypton in order to protect against heat loss from the room.

The warmest sliding systems offers professional sliding systems, among which you can find solutions such as: Yawal Moreview or Reynaers Hi-Finity, which are characterized by the best Uw = 0.8.

Despite its huge size, aluminum sliding doors are characterized by excellent thermal insulation. Uw = 0.8 means that patio windows with such a thermal coefficient are passive sliding systems.

The Uw parameter is extremely important for any window of any size and material. Uw informs you how much heat escapes through the window. In practice, it has to do with the cost of heating bills. The lower the Uw coefficient, the lower the bills.
