Yawal Moreview – review and opinion by debesto

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 patio doors, 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 patio door is U-Factor 0.12 Btu/h·ft2·F (Uw 0.7 W/m2K). The use of a 2.36 in thick glazing unit helps to achieve this result.

Frameless construction

Moreview sliding patio doors 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 1.06 in on the wing joint. This is an impressive result, which is nearly 0.39 inch better than solutions from Schuco (1.46 in) or Reynaers (1.38 in). However, there are companies that can boast a slightly better result. The central post in Aluprof or Cortizo is 0.08 in 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, 13 ft 1.5 in wide and 13 ft 1.5 in 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 patio doors can be up to 26 ft 3 in wide. This gives a total of up to 344.44 sq ft of glazing area.

An optional automatic drive is available for the Yawal Moreview system, working with loads up to 1,440.92 lb.

Construction of the threshold

The depth of the threshold slot is only 0.67 in. 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 doors (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.
