- If the total width of the opening is more than 900 mm, then it will be practical to install a double-leaf balcony door. At the same time, you will reduce the load on the fittings, so the door will serve for a long time even with intensive use without adjustment and repair.
- The design of the balcony door can be made from the Rehau profile line: Blitz, Euro, Estet, Sib, Delight, Brillant, Geneo or Edinburgh. The choice of one or another profile is carried out depending on the tasks that need to be solved. For example, if it is important to achieve high thermal insulation, then it is better to choose Rehau Sib. If you want to save on glazing, then take a look at Rehau Blitz.
- Selecting a filling option shutters is carried out based on personal preferences and the degree of illumination of the room. For example, if the door opens onto a glazed balcony, then the room may not have enough natural light, so it would be more logical to choose a door with transparent doors. There are situations when it is impractical to install a transparent door, in such cases, filling from sandwich panels is ordered.
- PVC doors have high thermal insulation performance, so even if your balcony is without glazing, you can be sure that the Rehau door will make your room as warm as possible and protect it from drafts.

The double balcony door is by no means a new fashion trend. This is an alternative to conventional single doors, because they are found in apartments, country houses, and office buildings.
Such doors received a special design, and hence the design and functionality that are different from other products.
Design and function
A double balcony door, unlike a single one, is equipped with two wings. Usually one leaf is responsible for opening and closing, and the second remains deaf. But sometimes both wings receive a mobile mechanism.
The first option is good because all the fittings are mounted in a blind sash - a strong support for the entire door. And in doors with two opening leaves, shtulp fittings are used for this task in order to do without an impost. Therefore, such structures are much more expensive.
On the other hand, double-leaf doors allow you to use the entire width of the opening and carry large furniture onto the balcony without any problems.
The role of double doors in the interior and their design
The double balcony door is wider than usual, its glass is larger in area. Due to this, it increases. This is true for dark rooms, the windows of which face north. The abundance of sunlight visually makes the room more spacious and refreshes the interior.
Doors with two leaves are open to experimentation with design. They can be laminated to look like wood and antiquity, painted in a variety of colors, decorated with layouts and stained-glass windows.
Balcony doors from Kaleva are also friendly to different decoration methods and allow you to create an individual design for any home.

Sincerely,
To design an exit to the balcony, there are a large number of options for doors. They differ in design, performance characteristics of the material, cost. Most often, balcony doors made of plastic profiles are installed, combining their excellent aesthetics and style with high performance in an original way.
Traditionally, a balcony door is installed as a single block with two or one window. Although today exits to the balcony, decorated with a separate doorway, are gaining wide popularity. Given its width, one- or two-leaf balcony doors are mounted. Openings with a width of more than 90 cm are equipped with two doors. Basically, this is a shtulp model.
The main sash is made 70-90 cm wide, the second one covers the rest of the opening. The auxiliary half is fixed with a latch and is mainly located in the closed state. Usually the passive sash is used as an additional source of natural light.
Shtulpovye double-leaf balcony doors are installed without an impost, as a result of which, when they are fully opened, the light opening increases significantly.
Shtulpovy door has the following original design. The additional sash is fixed on the latches at the top and bottom. It lacks a handle. Therefore, to open it, it is necessary to move the lever latch. On the inactive sash, a striker of the lock is installed, in which the bolt of the main lock is hidden. On the main half of the door is a plastic handle with a locking mechanism.
Double shutter doors to the balcony are very popular in country houses and cottages. Also, designers very often offer such models in new buildings, where large spacious balconies are provided. If desired, a double-leaf door can also be installed in old houses by installing an inactive sash instead of a window unit.
Bifold doors equipped with full-height double-glazed windows have become very popular among owners of balconies and loggias. But if you wish, you can install a plastic sandwich panel with a height of about 70 cm on one or both sashes.
Important! In order to equip an apartment with an exit to a balcony or a loggia with a double sash door, it is necessary to obtain permission for alteration in the architectural department.
Benefits of a double door for a loggia or balcony
Shtulpovye double-leaf balcony doors have a number of advantages:
- They allow you to organize an increased light opening, as a result of which the room will receive more natural light. This is true for rooms with insufficient natural light, for example, they are located on the north side of the building or the room has a relatively spacious area, and the window unit is small.
- Balcony double-leaf doors of the shtulp type perfectly complement various interiors, bringing some zest to the style. A huge texture and color range of modern plastic makes it possible to choose a model for even the most demanding taste of the owner.
- They allow you to significantly increase the viewing angle, which makes it possible to more comfortably admire your garden or the picturesque surrounding landscape.
- When organizing a meal in the family circle on the balcony, you can easily take out a large table through the double doors.
The stulp door to the balcony, made in the French style, looks very original.
A popular design of balcony blocks is the design based on double-leaf doors. They can be found in old buildings and in some new buildings, where the balcony opening allows you to place a pair of doors. This solution has a number of practical advantages. However, keep in mind that a double balcony door can be made in different versions, which directly affects its functionality and cost.
A double door, which is installed on a balcony, usually has a large glass area, so more light enters the room. High light transmission is the main advantage of double-leaf products.
For your information. The most popular type of double blocks are French doors, in which glass occupies at least 80% of the entire leaf area.
In addition to the conductivity of light, double-leaf balcony doors allow you to move large items. Therefore, on the balcony you can safely equip a seating area with upholstered furniture. True, a large free opening is not available in all types of double blocks, which will be discussed in more detail below.
A two-leaf balcony design with full glazing makes the room brighter and visually more spacious.
Double door with solid leaf
The presence of one working and one deaf section allows you to glaze a large balcony opening and save a little on fittings. Although such savings have the opposite effect - only half of the opening can be opened, which means that moving large-sized furniture becomes difficult to achieve. In terms of design, such a balcony system has two options - hinged and sliding.
This solution is not much different from the classic single-leaf design. The active part can function in a tilt-and-turn mode, for which a standard set of fittings is used: two hinges, a tape lock mechanism and a door handle. The fixed part fills the rest of the opening space, and its inner side simultaneously serves as a frame for the movable sash.
Note! Typically, the working and blind sections have approximately the same width, however, to increase the opening space, the active part can be made a little larger.
The main load during the operation of a double swing type balcony door falls on the hinges, which are designed to hold the entire mass of the leaf in the open state. With an increase in the glazing area, the load also increases, since the double-glazed window has a fairly impressive mass. Therefore, select the hinges taking into account their technical characteristics. In particular, pay attention to the permissible weight of the door leaf.
Double door with working and fixed sections
Moving the sash parallel to the axis of the balcony block saves space and looks quite original, so it is often used in modern interiors. There are several types of double sliding doors:
- Parallel sliding system (sliding). The shutters move along independent guides. Formally, none of the sections is deaf, but only half of the opening can be opened.
- Tilt-sliding system. In a double-leaf balcony door of this type, opening occurs due to special scissors, with the help of which the sash is slightly pushed forward and shifted to the side. The system can work in an inclined mode, allowing you to ventilate the room.
- Lift-sliding system. When closed, the sash fits snugly against the guide, creating the necessary tightness. When the handle is turned, the door leaf rises slightly, then it moves without visible effort.
Tilt-sliding and lifting-sliding structures are referred to as “warm” systems, therefore they can be used on open balconies
An interesting idea for organizing a balcony space is a shtulp door. Its feature is the ability to simultaneously open two sections and completely free the opening.
What is shtulp
Shtulp - a system of profiles, fittings and locking mechanisms, the task of which is to tightly connect two sections to each other. In this case, one half is working (active), and the second is dependent (passive).
Note! The active part of the sash balcony door is equipped with a standard handle and can operate in two modes - swing and tilt. The second leaf opens only after opening the working half and does not have an inclined functionality.
The presence on the passive leaf of the so-called false impost, to which the working half adjoins during locking, makes it possible to achieve a high level of tightness of the balcony block. Therefore, this design belongs to the class of warm balcony systems.

Design pros and cons
The advantages of a double sash door are an excellent view and the ability to fully open the opening. This is the optimal system for large balconies and terraces: you can not only effectively ventilate the room, but also take out large enough things.
The design also has several disadvantages:
- insufficient rigidity of the frame when arranging very wide openings;
- the complexity of installing and operating a mosquito net;
The problem of high load is due to the fact that in a sash balcony door one leaf clings to another, their total mass acts on the hinges. To avoid sagging canvases, a roller microlift is additionally installed at the bottom of each leaf. In the closed position, it takes part of the load on itself, unloading the rest of the fittings.
Shtulp system on the balcony allows you to completely free the opening
In order for a double balcony door to have sections of equal functionality, an impost is additionally mounted inside the frame. The design has greater rigidity and better functionality compared to the sash block, but it is used less frequently on balconies. The reasons for this choice of builders will be discussed below.
What is an impost
An impost is an additional vertical profile that divides the door block into two independent parts. Structurally, the impost is a bearing element, therefore it is reinforced with metal in the same way as the frame profile.
Note! On open balconies, the mullion is exposed to a higher wind load than the frame. This is due to the fact that the frame around the entire perimeter is anchored to the wall and thus transfers part of the load to it. Whereas the impost is connected to the frame profile only at two points.
The presence of a vertical lintel in the double door block makes it possible to use a standard set of fittings. Therefore, a double-leaf balcony door of this type, in fact, is a construction of two separate single-leaf doors.

Why the impost system is rarely used on the balcony
The use of an impost as a door space separator has a number of significant advantages. As noted above, the transom construction wins in rigidity from the shulp system. In addition, each sash can be opened individually in both tilt and turn mode. Installing a mosquito net also does not cause any particular problems, especially since mosquito protection can only be used on one half.
Nevertheless, there is one minus, which outweighs all the pluses in its significance - the presence of a jumper in the center of the opening. That is, even in a fully open state, there is no panoramic view, and it is also impossible to move large-sized furniture.
Since an open half is sufficient for access to the balcony, functionally such a system is not much different from a double balcony door with one blind leaf. The only difference lies in the wider possibilities for airing the room. However, the use of an additional door only as ventilation is impractical. Therefore, in wide doorways, shtulp blocks are mainly installed.
The use of impost is more typical for window openings
Specifics of double door glazing
The type and light transmission of the door structure largely depend on the area of glazing. The larger the size of the double-glazed window, the better the door looks and the more light enters the room. At the same time, double-glazed windows are the most expensive elements of balcony blocks, so an increase in the area and thickness of glazing significantly affects the cost of the product.
Another important point is the weight of the glass. For example, the mass of a standard single-chamber double-glazed window reaches 20 kg / m², and a two-chamber one - 30 kg / m². Therefore, in the case of French glazing, where almost the entire canvas is made translucent, the load on the frame and hinges increases significantly.
Note! In many sashes, a horizontal impost is additionally used, which is mistakenly considered by many to be a decorative lintel. In fact, such an element distributes the load between the entire profile strapping in the case of using heavy multi-chamber double-glazed windows.
The price of glazing depends not only on its area and the number of chambers, but also on the characteristics of the glasses themselves. Standard cameras with completely transparent elements are an economical option. For maximum heat retention in the house, the double-leaf balcony door should be equipped with energy-saving double-glazed windows with a coating that provides a higher level of thermal insulation.
The principle of operation of energy-saving glasses
Regardless of the type of double door that appeals to you with its aesthetics and functionality, consult with experts first. Only the master will objectively evaluate the possibility of installing a specific model, taking into account the characteristics of the balcony block.
