Yawal Moreview – review and opinion by debesto
2020 was the time of hot novelties in the segment of frameless sliding windows. One of them was the Yawal Moreview system, which officially debuted on April 1. In spite of associations that may arise at such a date, Yawal designers were far from joking. Moreview was solemnly announced by its developer as “the most innovative sliding door system with a hidden frame”. How much truth and how many marketing promises are there in all of these facts? Let’s check.
Which elements we review in this article?
Parameters
Investors are increasingly looking for large and impressive glazing, which must have high parameters. And here Yawal Moreview shows a new perspective. Due to the fact that these are frameless sliding windows, the manufacturer tried to maximize the glazing area while keeping the profiles as small as possible.
Heat transfer coefficient
The heat transfer coefficient that can be achieved for the entire window is Uw at 0.7 W / m2K. The use of a 60 mm thick glazing unit helps to achieve this result.
Parameter list
The list of the most important parameters is as follows:
| Maximum sash weight (manual) | 400 kg |
| Maximum sash weight (automat) | 1200 kg |
| Maximum weight of the fixed sash | 1000 kg |
| Maximum construction height | 4000 mm |
| Maximum sash width | 4000 mm |
| Maximum thickness of the glazing unit | 60 mm |
| Design depth of the sash | 72 mm |
| Visible width of the center post | 27 mm |
| Heat transfer coefficient | Uw from 0,7 |
| Soundproofing | Rw 42dB |
| Watertightness – resistance class | 9A |
| Wind resistance – resistance class | C4 |
Frameless construction
Moreview sliding windows allow the use of many different sash systems. Of course, the basic A and D schemes are available. You can also order structures in the G, C or K pattern, or practically any other configuration. The system maker included as many as 15. Even 6 movable sashes can be made in one structure (in a three-rail version). All possibilities are detailed in the graphic.
The width of the center post
The central post in Yawal is only 27 mm on the wing joint. This is an impressive result, which is nearly 10 millimeters better than solutions from Schuco (37 mm) or Reynaers (35 mm). However, there are companies that can boast a slightly better result. The central post in Aluprof or Cortizo is 2 mm narrower. However, these differences are practically imperceptible with such large dimensions.
Maximum glazing size
On the Yawal system, it is possible to produce a single sash, 4 meters wide and 4 meters high. Importantly, the system maker confirms that the maximum sash height can be used regardless of the width of the entire structure. This means that already in the basic A scheme, the Moreview window can be up to 8 meters wide. This gives a total of up to 32 m2 of glazing area.
An optional automatic drive is available for the Yawal Moreview system, working with loads up to 1,200 kg.
Construction of the threshold
The depth of the threshold slot is only 1.7 cm. The threshold can also be completely built up. The rollers are arranged in two lines. This allows for an even distribution of tension from the weight of the sash and reduces the risk of subsequent complaints from customers.
Sliding system
The industry standard is a sliding system based on trolleys placed in the sash in a deep “gutter” in the threshold of the frame. Yawal used an innovative solution in Moreview. The sash slides on rollers that are located in the frame of the structure (as presented in the video)
Drainage system
Yawal Moreview has a linear drainage integrated with the jamb. Due to the inclination of one of the walls of the bottom extension, even small amounts of liquid flow into the gutter without any problems. How gravity drain works in practice is shown on the video.
Innovations and differentiators
Innovation is one of the main ideas that guided the designers of the Yawal Moreview system when designing it. Below we have collected the most important innovations in our opinion.
Any number of tracks without cutting the rail
One of Yawal’s innovations is that Moreview can have any number of tracks that are joined by snaps and do not require the cutting of a wide track. The modular system allows this solution for structures that are not only two or three, but also multi-track. The only limit is the architect’s imagination and justification for the usefulness of such a large number of rails. It does not change the fact that it is doable and distinguishes the Yawal system.
Roller replacement without removing heavy wings
The rollers used in many frameless systems have often turned out to be a weak point as they have worn out over the years. However, Yawal found a solution to this problem. If Moreview’s bearings are worn, your customer can pull out the rollers and replace them by himself without removing the heavy sashes. The new variant of the rollers also eliminated the “clattering” while moving the sash.
Join sashes at any angle
The static post in the Yawal Moreview system allows you to construct a series of fixed glazing, which can additionally be joined at any angle thanks to the use of an all-glass corner.
Direct passage to the facade
As if that was not enough, the connectors allow you to go directly from Moreview to the façade, giving you even more arrangement options.
Warm, non-threshold building
Building without a threshold is a solution that is currently very popular and expected by your customers. Companies that offer frameless systems either already offer a construction with no threshold or plan to use this solution in the near future. What distinguishes Yawal is a thermal break that eliminates a thermal bridge.
Design
Design is undoubtedly very important to Yawal Moreview designers. Below are the design elements that we think stand out:
Aesthetic masking of the sash forehead
The inner part of the sash profile has an aesthetic black masking cover that hides the normally visible fitting elements and additionally emphasizes the minimalistic design of the frameless structure.
Rollers in two colors
Yawal Moreview stands here for design as well. The rollers are available both in silver (inox) and black (made of polyamide – less scratch-resistant).
Installation without threshold thanks to the slotted frame
Yawal announced that from January 2021, the Moreview variant with a slotted frame will be available, i.e. without a visible threshold. The sash will be connected with the trolley by an I-section.
Asymmetrical joints and pocket-doors
The system also provides asymmetrical corner connections – even triple ones. It also gives the possibility to create “pocket door” (galandage) doors. After opening, they hide in the wall of the building in a specially designed “pocket”. It significantly increases the passage clearance after opening the sashes.
Summary and product card
Yawal delivers quality at an affordable price. Moreview is a new system on the market and in our opinion it definitely deserves attention. Both high parameters and affordable price, which is one of the lowest on the market, speak in favor of the market novelty.
