In low-rise construction, portals serve mainly to provide access to a terrace or patio, and in cities they are often installed between a loggia and a room instead of a standard balcony block (window + door). Please note that such redevelopment in a standard apartment requires prior approval from the housing inspection authorities.

Today, the greatest demand is for parallel sliding doors with the function of tilting the sash for ventilation. They are more reliable than folding ones and much cheaper than lift-and-slide ones; fittings of this type are accessible and easy to install. Photo: "WINDOWS OF GROWTH"

The portal saves useful space, perfectly insulates heat and sound, visually expands the boundaries of the room and allows you to temporarily combine a room and a loggia. It is also important that it fully complies with the engineering and design concept of a modern home. Depending on the type of fittings, portals are folding (accordion), parallel-sliding and lifting-sliding. Which design should you prefer?

Window companies classify portals as non-standard products, so their production time almost always exceeds 2 weeks. In this case, the measurement of the opening and installation of the structure is carried out by the manufacturer.

What are portals

With a sliding system you can open your window in a completely new way! The window sash can simply be retracted to the side, leaving more free space in your home.

Window portals are:

• More light;
• More style;
• More space;
• More comfort

Sliding windows will retain all the useful properties of high-quality plastic structures: sound insulation, thermal insulation, safety, indoor climate control.

Let's give a couple of examples

Many people know the situation when, due to life circumstances, it is necessary to divide the living room into two parts. A standard solution with a blank partition can hardly be called aesthetic and functional, while the design of such zoning using a glazed portal with sliding PVC doors not only solves the problem, but also brings a special style and individuality to the interior.

Such systems are appropriate not only in residential buildings, but also in business. For example, in a cafe or restaurant, using door portals, you can transform the dining room into an open summer terrace, and vice versa, with the onset of cold weather, close the outline of the room, maintaining excellent illumination.

Possibility of using portals

Portal windows are sliding structures that are unique in their kind and have a wide range of application possibilities.
Sliding windows will fit perfectly into the interior, replacing the usual balcony doors. Instead of the usual walls, there are floor-to-ceiling window openings that open to the side without taking up extra space. Sliding glazing - it's easy!

You just need to turn the handle and move the sash to the side with a slight movement using special hinges. The sash can slide either onto a blind window sash or simply onto a wall. In this case, you can choose either a cold type of glazing or warm sliding windows.

If you are the happy owner of a country house or cottage, window portals will open up a stunning panoramic view from the house to the terrace, because sliding structures allow you to make large-sized sashes that fit the entire wall. The PSK Portal 160 sash opening system can support sash weights of up to 160 kg.

By installing portal windows in your home, you get the following:

• large sashes that create a panoramic view from your window;
• saving such important living space;
• unique design solution;
• all the best properties of plastic windows - thermal insulation, sound insulation, climate control, safety.

If you need to glaze an apartment or a small country house, getting more light and space, glaze a veranda, greenhouse, access to a terrace or pool, or get a unique exit to a balcony block, then the sliding window system is the ideal solution to these issues! You can also pay attention to sliding wooden windows, which will give your apartment or cottage a special style.

Si-line PSK handles for portal doors from 3500 rubles

The PSK Portal 160 portal structures use original Si-line PSK handles (Germany). The handles have a modern design and are convenient for operating large doors. For portal doors we offer 5 color solutions for handles and decorative overlays (availability to be confirmed). Colored accessories are used with white or laminated PVC profiles.

PSK Portal 160 fittings for the Russian market are produced at SIEGENIA GRUPPE enterprises in Germany from high-quality steel. The system has been extensively tested and all parts are thoroughly checked. PSK Portal 160 allows you to produce a structure with a maximum frame width of 3460 mm, height of 2300 mm (dimensions of the rebated sliding sash are 1600x2240 mm).

OPENING THE PORTAL DOOR PSK PORTAL 160

Portal systems of windows and doors: pros and cons

The principle of operation of the sliding system can be judged from its name. In this case, the sash is suspended on hinges that move along slats integrated into the frame from the inside. At the moment of opening, the hinges unfold and the sash moves out of its seat into the room.

Then the sash is directly moved to release the opening - the hinges with the sash move along the slats along the plane of the frame. Often the sash handle has the possibility of intermediate fixation. During the reverse movement, the hinges fold and the sash fits into the seat.

According to the scheme of movable doors, there are three most popular options:

1. “Patio” - one leaf weighing up to 100 kg.
2. HS-portal or simply “Portal”. Two doors weighing up to 160 kg, diverging in different directions. Can clear openings up to 3 m
3. FS-portal or “Accordion”. The sashes weighing up to 80 kg are interconnected alternately - one row of hinges on the outside, the other on the inside. As a result, when moved, the doors fold in the manner of an accordion bellows. This arrangement allows you to cover openings up to 6 m.

The portal window system can be external and internal, fixed and glazed, plastic and wooden. The essence of the differences comes down to the opening method, since the seats and frame design are usually identical.

The parts themselves - hinges, slats, rods - are fundamentally similar and repeat the original design of the hinge-recoil mechanism, originally proposed by the German company Roto. As the size of the sash increases, its mass increases, which leads to the need to use more powerful and larger parts.

Almost any material can be used in the manufacture of portals. The three most popular versions:

• Metal-plastic. Reliable, simple and technologically advanced, like all metal-plastic products. The main advantage is a large assortment of frame and sash profiles, which allows you to choose even a budget model.
• Aluminum. Exceptional durability and reliability. But at the same time, the thermal insulation performance is below average. More suitable for unheated balconies, verandas, greenhouses and summer gardens.
• Wooden (“Eurowood”). TOP segment products with the highest prices. They can be made of valuable wood, which makes them an exclusive element of the interior and exterior at the same time.

Particularly elegant are sliding portals, in which the canvas, when opened, goes into a niche inside the wall. In this case, the door is part of the partition structure and is designed together with it.

The sliding mechanism can be a hanging rail hidden in the upper part of the portal, onto which the door leaf is hung through rollers. In another embodiment, a support rail (profile groove) is cut into the floor, and the canvas has a support roller (or rollers) that fits into this rail.

Sliding (sliding) systems are less common due to their higher price, but they have a number of tangible advantages over swing systems:

• Clearing the opening does not require additional space near the frame. This allows you to install such windows and portals in narrow corridors and rooms with non-traditional wall layouts.
• The open sash does not take up space next to the frame, does not require fixation, and remains motionless. The sliding sash is easier to adjust and will not slam shut due to a draft.
• There is no risk of damage to the opposite wall or frame due to an impact as with a swing sash.

The main advantage of window portals - a visual increase in the space of the room due to a completely transparent wall - is best demonstrated when used as a passage to the terrace. In city apartments this is no less relevant - a loggia glazed with blind portals will make the view from the window full and panoramic.

Types of sliding systems

There are three types of portals on the market: PSK systems (parallel sliding); FS systems (folding, otherwise known as accordions); HS systems (lift and slide).

Parallel sliding systems - to open the sash, it must first be pushed forward from the opening, then moved along the guides to the side. In premium segment portals, the process is simplified and the sash extends automatically when you turn the handle, which is much more convenient. The maximum leaf width of a PSK portal is 2000 mm; the leaves are not combined with each other, which allows you to combine portals with blind blocks in any order and cover openings of almost any length.

Folding systems - the doors are fixed to each other with hinges, moved to the side or pushed apart using rollers that roll along the “rails” built into the frame. Sliding portal systems are installed in an opening of no more than six meters, the width of the sash is usually in the range of 500-900 mm. Such a system ensures almost complete opening of the portal if necessary, but a smaller proportion of glazing due to a larger number of frame parts affects both viewing properties and insolation.

Lift-and-slide systems - the opening principle is similar to parallel-sliding ones, but the sash does not move forward, but rises slightly up and rolls to the side. The main advantage of systems of this type is the high load-bearing capacity of the mechanisms. The double-glazed window can also be three-chamber, which is important if we are talking about cold regions or houses with minimal energy consumption.

The choice of one system or another depends on the specifics of the application.

So, we are slowly rebuilding a house built in the 90s “from what was there”, we have a rebuilt roof, and at the same time a new roof over the balcony-terrace. The task is to turn the balcony into a kind of winter garden, so that in winter it would be almost a single room with the main house (we will make the floor level, and we will install a purely symbolic door, perhaps just thin glass). But in the summer it should be a normal balcony, i.e. the glazing should open to the maximum, the second floor and an insulated version, plus the possibility of opening. They recommend choosing an accordion or portals; the tightness of the accordions is confusing, and the portals have too many fixed parts. What do you advise?

Dmitry ShorinLead product manager of the window and door fittings department

The ideal solution for this task is a parallel sliding system. Windows and doors with a sliding system are practical, take up minimal space in the room and retain heat well thanks to uniform pressure. This unique system is equipped with special closers for closing the sash, provides ventilation around the entire perimeter of the window and has a burglar-resistant function. The sliding system allows the manufacture of large structures without imposts, which ensures maximum light flow into the room. The dimensions of the portal can reach 2 meters in width and 2.4 meters in height. The use of specialized fittings guarantees excellent clamping, since the adjustment range of the locking pins is at least 20% higher than that of any other fittings. At the same time, the rotating heads of the trunnions and the perforation of the sash elements of the fittings will make the movement of the window handle soft and smooth even with a large number of pressure points. Such fittings are much more reliable and durable than analogues.

What to look for when choosing and installing a sliding portal

Problem #1

The possibility of freezing of a double-glazed window often stops those wishing to install a transparent portal at the exit from the room (at the border of the temperature difference). There is only one way to avoid this - to organize additional ventilation with heating inside the room.

Traditionally, heating radiators are installed under windows for a reason. Hot air rises and heats the glass, preventing condensation from forming. To heat portals that “rest” directly on the floor, convectors built into the slab or floor screed are used. They can be connected to a heating system or “warm floor”.

Problem #2

Installation defects. Violations during the installation process can result in any surprises. TOP 3 problems with incorrect installation:

Over time, the system jams, jams, and runs slowly. It is most often found on multi-section “accordions”.

What to do? Arm yourself with a hexagon, patience and use the tips from our article.

Drafts. Incorrectly installed polyurethane foam is the main cause of drafts.

What to do? Open the perimeter of the frame or the place of the draft and check the quality of the insulation.

Installation on temporary fastenings. If you find that the window or portal is installed only on scraps of the U-shaped suspension and foam, the structure should be strengthened.

What to do ? Drill holes into the wall directly through the frame and install dowels or dowels Ø 10 mm and 150–180 mm long.

Of course, these are not all possible defects. In most cases, in order to correct the situation, it is necessary to open the exterior or interior finishing. If you have the opportunity to control the installation of portals, do so. And demand explanations at every stage.

Problem #3

The attractiveness of portals for burglars. There is an opinion that any sliding system is easy to open or hack.

Violators are constantly improving their skills, but manufacturers are not standing still. When choosing an external portal, pay attention to the presence of an anti-burglary system. Most manufacturers offer anti-burglary kits for already released models of windows and portals.

Manufacturer

Orders for lifting and sliding doors made of PVC or aluminum are accepted only by large companies. It is best to contact directly the representative office of the window profile manufacturer (Rehau, Deceuninck, profine Group, VEKA) or large manufacturers of wooden windows.

Parallel sliding and folding doors are produced by many window doors, “Kaleva”, “Okna Rosta”, “Window Factory”, “YUKKO”, etc.). Please note that the company is required to provide at least a one-year warranty on the design and installation work.

Before ordering a portal, it is advisable to study samples of finished products at a construction exhibition or in the manufacturer’s showroom, paying attention to the ease of control of the sashes and the smoothness of their movement.

Sliding doors FS portal, or accordion portal

A folding accordion sliding door is an original design solution that can become the main highlight of the interior. Fs portal window-doors are used where the entire opening needs to be opened, both for purely pragmatic and aesthetic purposes. The accordion system is an alternative sliding method that operates through the presence of ball-bearing rollers in the trolleys.

Folding sliding systems are characterized by the absence of an impost - a fixed vertical or horizontal element of all casement and some sliding window structures.

These features of the fs design make it possible to almost completely open a passage more than 6 m wide to a veranda or terrace, and one leaf will work as a swing or tilt-and-turn door. When folded, the entire composition is assembled with a “curtain” on the side of the opening, revealing a luxurious panoramic view. When closed, the Fold-slide portal provides complete tightness and thermal insulation.

Profile material

Modern fs window (door) portal is available in the following variants:

• pvc;
• wooden portals fs;
• wood-aluminum and Al profiles.

Folding systems fs are often equipped with a Rehau Euro Design profile, suitable for any configuration.

When installing, the dimensions of the product must be correlated with the presence of additional profiles.

Design nuances

Fs system "Accordion" provides maximum utilization of the space of glazed doorways, inaccessible to other systems. Technically, this is due to the fact that when opened, the doors fold like an accordion at an angle of 95° to the frame.

The doors can move to the right or left, as well as in both directions, depending on the opening pattern. In addition, the folding accordion door can open both inside and outside the room.

Easy movement is ensured by 4 rollers on ball bearings made of high-strength polymer in rails. Even a child can open such an fs portal.

It is possible to install the carrier rollers in the lower or upper position.

Plastic sliding doors: prices and popular types

To calculate prices for plastic sliding doors, the Rehau Blitz profile and energy-saving double-glazed windows were used, ensuring reliability, durability and energy efficiency of the structure. The price is valid when ordering 2 or more products.

Threshold types

Placing the supporting rollers in the groove (lower niche) of the fs portal with an aluminum threshold allows you to recess the lower guide almost flush with the floor. No more than 10 - 15 mm of the profile will remain above the surface, which makes the operation of the fs accordion door more comfortable and practical, but slightly increases the thermal conductivity of fs systems, although the lower rollers are protected by a brush seal.

The barrier-free version of the threshold is equipped with FS portal Siegenia fittings.

A threshold in the form of a regular frame is warmer and cheaper, but it creates inconveniences in movement. GU portal KF is added to the mentioned fittings.

Advantages of our offer

1. Own production on automatic equipment and supply of supporting portal profiles from rehau. This is a guarantee of reliability and accuracy.
2. Possibility of using standard designs for openings, individual design for measurements.
3. Execution of guarantees under the contract - for the assembled portal, for the result of work, for German fittings.
4. System maintenance after installation.
5. Measurements, design and installation are carried out only by the company’s full-time specialists. We do not involve third parties.

Limitations of use compared to other systems

The Fs portal can be designed as an entrance door or a window/balcony system, as well as an interior partition.
The type of opening and the number of sashes fs of the accordion design vary, but the number of structural elements should not exceed 7 pieces, and the weight of each sash is limited to 80 kg, while, for example, HS lift-slide systems can withstand loads of up to 200 - 400 kg per sash, and in parallel - sliding PSK options – up to 200 kg.

Thanks to the variability of fs opening types, the window portal plus can be installed in any opening, but the largest opening width is 6.3 - 6.5 m. For comparison: hs portal is designed for glazing the widest openings.

Areas of use for accordion glass doors:

• separate heated loggia in the apartment,
• extensions (verandas, gazebos, greenhouses) in country houses, cottages,
• shop windows,
• recreation areas in restaurants and cafes,
• meeting rooms and offices.

The use of fs portal plus in small apartments with small balconies is not entirely justified.

The limitations of using an fs portal accordion compared to PSK and HSK portals are due to the fact that this configuration requires particularly careful operation, because folding doors can become loose over time, especially if they are not fixed when used in ventilation mode in windy weather.

With a large number of sashes, the risk of blowing increases, which reduces thermal insulation, which means that in severe winter conditions it is better to use other portal systems (more airtight).

A high threshold (aluminum-free version) is not suitable for installing an accordion in places with a large flow of people, because it is difficult to step over it.

Design and operational features

The functionality, characteristics and method of opening portal units are determined by the fittings, which ensure safety, ease of control, and various operating modes.

Dmitry Shorin

Advanced portal systems of the latest generation are characterized by an optimal set of parameters.

• Safety – ensured by an opening blocker from the street side during ventilation.
• Ease of use – the door closer system makes opening and closing easy, regardless of the weight of the sash.
• Smooth running - if necessary, adjustment is carried out with a standard key.
• Good thermal insulation is achieved through energy-saving double-glazed windows, an increased number of fitting pressure points and seal contours.
• Practicality - they do not take up space when opened, they can be opened for ventilation, there are closers and blockers for erroneous opening.
• Aesthetics – they look more presentable than ordinary doors.

​However, many are skeptical about portal systems - they are confused by the complexity of installation and ease of use.

kam711FORUMHOUSE Member

Initially, I wanted to install sliding portal doors, only taking into account all the problems with installation, I very quickly abandoned this idea. And in terms of ease of movement, they are a bit difficult to open, especially if there are children in the house. Maybe everything will be fine in exhibition samples - but after a couple of years of live operation, I’m not sure.

Dmitry Shorin

At first glance, installing any sliding structure seems very difficult. The wide variety of elements, plus the sheer size of the structure, scares off buyers. But there are always professionals who easily and without problems assemble 10-15 portals a day. Thanks to the perimeter fittings in sliding systems, opening and closing the sash occurs very smoothly and easily. Ease of movement is ensured by:

Special perforation on moving parts of the fittings. This creates point contact between the parts, which, unlike complete contact, leads to reduced friction and easier sliding of the mechanism.

1. Unique rotating locking pins extend the life of the structure.
2. Sufficient amount of factory lubricant on all moving parts.
3. Therefore, if you choose a design using high-quality fittings, then problems with the ease of movement and durability of the portal system can be avoided.

AlexD50FORUMHOUSE Member

The RSK portal is inconvenient for frequent opening and closing.

Dmitry Shorin

Thanks to the patented system of hydromechanical closers, the sash control in sliding systems is as smooth and safe as possible. At the same time, the use of window fittings in the portal frame makes the movement of the window handle smooth and soft, the design is easy and convenient to use, and the fitting elements will work reliably at any temperature and wind loads.

Advantages and disadvantages

Like other FS designs, they have their advantages and disadvantages.

The strengths of the accordion are due not only to functionality, but also to aesthetic qualities:

• maximum space without sashes on the sides and stiffeners in the area of ​​the glazed opening;
• easy silent movement;
• long service life due to anti-corrosion coating of fittings;
• possibility of ventilation with a closed portal;
• availability of remote control (optional);
• a large selection of hinges, trunnions, handles and other accessories; the handles can be removed in order to move the accordion to the side as much as possible when opening the entire width of the opening;
• a variety of opening patterns and directions (some of them provide for the presence of one tilt-and-turn flap);
• high sound insulation;
• resistance to precipitation penetration;
• thermal insulation is not lower than standard indicators for portals made of wood, PVC, aluminum (also depends on the double-glazed window and the type of threshold);
• the aluminum threshold allows you to recess the profile almost flush with the floor;
• anti-burglary protection.

Disadvantages of fs systems: the likelihood of blowing through with a large number of fragments and a high threshold in structures with frames without the use of aluminum.

Main characteristics of portal systems

* In addition to the type of construction, the cost of the door depends on the material of the frames, the type of glass unit and the number of movable sashes.

Parallel sliding portals - PSK portals

PSK portal is a structure for arranging entrance openings, including exits to neighboring rooms inside the building or to the courtyard, balcony, terrace, summer area.
The specificity of the design lies in the mechanism for fastening the sashes, which involves movement along the frame. PSK portals with parallel-sliding doors of the Krasnaya Gorka brand are in demand among practical people with a subtle sense of style, who are looking for ways to decorate the interior of their home effectively and efficiently.

Parallel-sliding portals are especially relevant in view apartments in high-rise buildings or rooms with a panoramic view of the picturesque surroundings. PSK portal is a structure for arranging entrance openings, including exits to neighboring rooms inside the building or to the courtyard, balcony, terrace, summer area.

The specificity of the design lies in the mechanism for fastening the sashes, which involves movement along the frame. The canvas moves smoothly in the direction left and right, running over the adjacent block. We must pay tribute to the inventor of such an ergonomic system as the PSK portal, which allows you to effectively use literally every centimeter of usable living space, which is equally valuable for the owner of a mansion and the owner of a small apartment.

To open silent, airtight, reliable doors equipped with a double-circuit sealing system, no additional space is required; furniture or other interior items can be located almost right next to the sash.

You can hear positive reviews from experts, designers and consumers regarding the popular PSK portals regarding practicality and quality; the only drawback is the high cost of the products.

According to internal statistics, our clients are satisfied with the loyal price for PSK portal, because we work without intermediaries, and we also provide a full package of high-quality services, including measurements, installation and maintenance of the system under warranty and during the post-warranty period.

The cost of a specific model is determined by the technical characteristics of the PSK portal sliding door system; customers can control their costs by selecting only the options and functionality they need: wood type, glass tinting, installation of tempered glass.

When manufacturing sliding portals, one should be guided by proven standards, which is why restrictions on overall dimensions are practiced. In order to increase the trouble-free service life, the sash should weigh up to 200 kg, and the size of the portal should not exceed 4,260 mm. The optimal permissible width of the moving web is up to 2000 mm, height – up to 2,360 mm. It must be taken into account that PSK systems are always a portal with a threshold.

Ventilation function

If you ventilate rooms by fully opening the doors, you cannot avoid a strong draft and hypothermia of the air, so it is advisable to choose a sliding design with a slot ventilation function.

Fitting systems for folding doors provide ventilation by tilting (tilting) one of the doors, however, this function is optional - you will have to pay an additional 4 thousand rubles for it.

Parallel-sliding sashes with Portal PSK and Patio S fittings also take an inclined position, and in the MACO PAS system the leaf moves along the entire plane - while a gap of about 5 mm is formed along its perimeter. The tilting method provides greater thermal comfort (the flow of cold air is directed towards the ceiling), but moving the sash is preferable from the point of view of home safety: from the outside it is almost impossible to notice that the door is slightly open.

The micro-ventilation function is also present in lift-and-slide doors: when the handle is turned 45°, the door leaf moves back a few millimeters and is locked.

Types of PSK portal

There can be several sliding doors in a portal; 2, 3, 4 or more leaf systems can consist of stationary, sliding or swing doors. It is recommended to glaze the PSC portal using pine, oak or larch timber.

There are the following schemes for opening the PSK portal:

• A - the window opening is divided into 2 parts and the sash is moved onto the blind element of the window
• C – the window opening is divided into 4 parts, the sliding elements are located in the center of the opening and move left and right
• K - the window opening is divided into 3 parts, the central element is blind, the movable sashes move to the center.
• G – is a special case of scheme A

There is also a variant of the installation situation, where the PSK portal has only one sash - a movable one, which, when open, moves along the wall. In this case, the sash can be built into a special box, so that when open it will not be visible.

Lift and slide doors - HS portals

We offer two options for lift and slide doors:

• HS portals - sliding doors made of wooden and aluminum profiles
• Vekaslide - sliding doors made of Veka PVC profile

Application area:

• in suburban construction - entrance doors, exits to swimming pools, winter gardens and greenhouses, to closed and open terraces;
• light-transparent partitions with the possibility of combining space;
• entrance doors in shopping centers, hotels and other public and commercial buildings where an entrance with a large opening area is required;

Frame material

Portal frames are made of PVC, “warm” aluminum, solid wood, and a combination of wood and aluminum.

For a parallel sliding door, so-called intermediate PVC profiles are suitable; they are stronger than window profiles, but not as wide as door profiles. PVC frames are the most affordable, but due to the flexibility of the material they are slightly loose, and the sash size should not exceed 2200 × 1100 mm (for laminated products - 2100 × 900 mm).

Photo: Alumil

Doors made from laminated solid wood are rigid and practically not subject to thermal expansion, so their dimensions can reach 2500 × 1200 mm. However, a wooden (pine) portal will cost 30–40% more than a plastic one.

Products made from “warm” aluminum are the most expensive. They cost 2.5–3 times more than plastic ones, but frames made of this material are the strongest and most durable and, moreover, due to their small width, allow more light into the rooms. A parallel sliding door can be made from regular aluminum window profiles, while a folding door can only be made from special ones, for example Schüco ASS 80 FD.HI.

The maximum height of a structure made of plastic profiles laminated with wood-look film is 2400 mm. Photo: Rehau

Lifting and sliding fittings are equipped with frames made of plastic, wooden or aluminum profiles specially designed for this design (VEKASLIDE, profine PremiDoor, Schuco ASS 70.HI, etc.), which are much more expensive than window ones. But only such products can be equipped with a low-profile threshold that can be easily overcome by a person in a wheelchair.

Wooden HS portal

The HS-portal, made of wood, is a very convenient and reliable door entry system.
It has a low threshold, only 19 mm, which can be mounted into the floor. It also has the ability to install a barrier-free threshold, which is very important for people with disabilities. Depending on the purpose, requirement and design solution, you can select the required portal opening system.

Application area:

• exits to swimming pools, winter gardens and greenhouses, indoor and outdoor terraces;
• interior partitions with the possibility of combining space;

Specifications:

• maximum portal width 5300 mm;
• minimum sash width 700 mm;
• maximum sash width 3300 mm;
• maximum sash height 3250 mm;
• minimum sash height 850 mm;
• moving sash weight up to 400 kg;
• built-in micro-ventilation function;
• two sealing circuits;
• thermally insulated aluminum threshold;
• reliable engagement of the sashes: movable and non-movable

Limitations and additional mechanisms:

• the ratio of height to width of the sash is no more than 2.5:1;
• if the sash weighs more than 300 kg, additional carriages are required;
• if the sash weight is more than 100 kg, a sash lowering shock absorber is installed;
• “Security” option - anti-burglary strips between the outer and inner doors;
• option “Comfort” - a mechanism for smooth opening of the doors;
• “Barrier-free linings” option – provides a smooth change in threshold height.

Reasons to install the VEKA portal

• Maximum illumination of the room thanks to the increased light opening allows you to save energy.
• Functionality - you can manage the space by dividing it into separate zones or combining it.
• Convenience and aesthetics - the glazing is easy to operate, the portal door makes the interior exclusive.
• High heat and sound insulation - glass package and fittings, when chosen correctly, provide excellent protection from street noise and a comfortable microclimate.
• Durability - the VEKA portal has been in use for decades and is undemanding in maintenance.

Security - installation of burglary-proof fittings allows you to more reliably protect the room from the entry of strangers from the street.
