In old and modern apartments, you can often find doorways of non-standard, wide sizes. The best option for their design are double-leaf interior doors, the main feature of which, unlike conventional single-leaf doors, is the presence of two door panels. They can have different widths and functional affiliation. Often one leaf is in a fixed position and opens only when necessary, and the second canvas is used for everyday use.
Types of double doors
Any doors in which there are two doors are called double doors, or double doors. According to their design and principle of operation, they are divided into three main groups:
- swing (as an option - pendulum, or swinging);
- sliding (as an option - sliding);
- folding.
In a doorway with a width of more than one meter, it is advisable to install double doors, since one leaf in a wide opening will be too heavy and will significantly increase the load on the door frame, hinges or guides. The sashes can be exactly the same or mirrored, differ in size or design. A non-working, closed canvas often has a smaller width and is performed "deaf", but this is not necessary. Designs look interesting in which both canvases are decorated in the same way, but one of them is a narrowed version of the other.
Two-leaf interior doors are made from all materials intended for these structures or their combinations:
- metal - usually in the form of a frame;
- wood - the most common or valuable species;
- Chipboard or MDF - painted or laminated;
- plastic;
- glass.
The main criterion for choosing double doors is the style decision and the overall design of the room or the whole house. According to the design of the sash are:
- smooth deaf;
- typesetting;
- paneled convex;
- massive carvings.
Type-setting canvases combine two or more types of materials. Inserts can have different sizes, configurations, combinations of colors, shades and materials. As a rule, insert into the main frame:
Double-leaf doors are made of traditional rectangular or non-standard shape - arched, with smooth curves, of various geometries.
Double swing structures
Swing canvases are hung on different jambs of the door frame with the help of hinges. They can open in one direction - inside or outside the room, and in both directions (pendulum door). Most often, such structures can be seen at the entrance to the living room or large dining room (dining room). They look hospitable and noble.
The most popular are models with glass inserts that add visual space and openness. But for rooms of a large area, it would be more respectable to put a door made of solid wood with carved inserts.
Double sliding doors
Such designs save the surrounding space. They are installed in the event that there is not enough space for opening swing analogs or sliding doors are provided for by the design project.
The canvases move in one or different directions along the guides, thanks to a special sliding system. The sashes of retractable double-floor models, opening, are hidden in walls or partitions in which cases are mounted.
Double folding structures
Book doors fit perfectly into a small room. They are made of light materials, more often - plastic. The sashes of one canvas are interconnected by small loops, and when the door is opened, they fold vertically. Such models do not have a very presentable appearance, so they are installed in dressing rooms, utility rooms. Although as an economical option, they will quite cope with their function.
There are quite a few varieties of ready-made double doors on the market. They can also be mounted from two separate canvases, making a door frame of the required size. But if the opening has a non-standard width, then you should not despair - in any specialized store it is possible to order an individual design by choosing the design of the door and the material from which it will be made in full accordance with the measurements from the catalogs.

Quite often in apartments and public buildings, especially in older buildings, there are wide doorways. Undoubtedly, it is beautiful and convenient, however, if it is necessary to replace old doors, it will be problematic to install a standard canvas. In order not to block part of the passage, completing the wall, it is better to install double-leaf doors in such an opening.
double door design
A two-leaf door is a product of any type of opening that has two leaves. So, the design can be both hinged and sliding. At the same time, in swing structures, one of the canvases can be fixed in the closed or open position, and the second one can be constantly operated. Each of the wings can have absolutely any engineering allowable width.
Based on the principle of location and the main functions of the paintings, double doors can be:
- Input, most often made of metal;
- Interroom;
- Special purpose products in the form of fire doors.
Entrance double doors
Most often, double-floor entrance structures are installed in large public buildings. Installation of such doors is possible provided that the width of the opening exceeds 800 mm. The most common width of the valves with a total size of 1200 mm. Such designs are justified in office, financial institutions, as well as in places of recreation and shopping malls.
When placing doors of this type as warehouse entrance door structures, their width can reach 1500-1700 mm. And in the case of using doors in places where bulky goods are moving and the possible movement of vehicles of various sizes, the total width of the canvases is more than 1700 mm.
Any two-leaf metal door consists of two main parts: a welded or solid curved frame common to both leaves and two canvases of the same or different widths. The main convenience of these structures is the possibility of opening both one part of the opening with partial overlap, and the full one, using both wings.
Quite often, when operating in a zone where a large number of people move, for ease of use, metal double-leaf door structures are equipped with a pendulum system. Thus, a high throughput of the doors is ensured. In this case, the width of the door leaves must be the same.
Construction of a metal double door
Door leaves are assembled from steel sheets with a thickness of 1.5 mm. Steel coating can be placed on one or both sides of the product. The inner part of the web is reinforced by the placement of special stiffeners. Not all products have insulation and soundproofing material.
Cloths can be of a deaf type or have partial glazing. At the same time, the placement of decorative inserts, their shape, size and symmetry in relation to the paired canvas are absolutely not regulated by anything.
As a material for finishing the product are used:
- Natural wood veneer;
- Laminate;
- MDF sheets;
- Artificial leather;
- PVC film;
- Ship plywood, resistant to various weather conditions;
- Plastic;
- Powder coating.
In most cases, the outer part of the double-leaf entrance door is covered with a material that is resistant to various weather conditions and protects the metal from corrosive processes. The inner side of the product for the most part performs a decorative function, so the coating can be absolutely anything.
Interior double doors
Interroom double-leaf door structures can be made from almost any material. Quite often, one and a half doors of this type are installed in apartments. In such products there is an asymmetry in the width of the canvases. At the same time, the smaller fixed sash, in most cases, is deaf, and the wide frequently used canvas is equipped with various decorative inserts.
Also, quite often, a double-sided interior door is made of glass. This solution allows you to fill the room as much as possible with natural light and visually significantly enlarges the room. In addition, as the main material of manufacture can be used: natural wood, MDF and chipboard, plastic profile, metal.
A feature of interior doors of this type is the possibility of equipping the structure with a pendulum-type opening system. Thanks to this, the door leaves can be opened on both sides of the frame. Such an engineering solution is very convenient for living rooms and apartments with large hallways.
The only drawback is the inappropriateness of installing these products in small spaces. Due to their width, double-leaf doors will not only occupy almost the entire existing wall, but also visually reduce an already small room.
Fire doors with two wings
Quite often at present there are double-leaf fire doors. The use of just such a design is quite justified, since the product, due to its width, has a high throughput and is very convenient for placement.
As the material from which these doors are made, special heat-resistant steel is used. Often the design is complemented by tempered glass inserts. Despite the ability of the door material to withstand high temperatures, fire and smoke, the product has a relatively low weight. This is a significant advantage of the door, since most wide doors are quite heavy.
In the event of an emergency, a steel double-leaf fire door will not only allow you to quickly and efficiently evacuate, but also make this process simple even for a weakened person or child.
Double-leaf fire doors are equipped with special overlays that ensure tight closing of the doors and, as a result, almost one hundred percent tightness of the product. To ensure high reliability of the structure, as well as ease of operation, fire doors with two leaves are equipped with separate elements of independent fittings.
Fire doors with two wings are in most cases installed in such public and private facilities:
- production shops;
- Large commercial buildings;
- Warehouses with the need to move oversized cargo;
- Laboratory premises;
- Offices in large complexes.
The main feature of the doors is the ability of the protective layer of the filler to foam during prolonged exposure to elevated temperatures. Due to this, not only the tightness of the product increases, but also the shape of the structure is preserved for a long time. Thus, the double-leaf fire door is not subject to jamming and distortion during a fire, which corresponds to the high safety indicators of the product.
Doors with two leaves are the optimal solution for large openings, as well as for apartments, offices, shops, private houses, the operation of which requires the organization of maximum door throughput. So, a double-leaf door is perfect for a banquet hall of a restaurant designed for 50-150 people, this will not only provide convenience to guests, but also allow you to rearrange furniture and tables without any extra effort, if this is required by the event plan.
Often, double-leaf doors are installed in vestibules, office premises, this contributes to the comfortable operation of the premises, as well as increasing fire safety measures, facilitating the process of evacuating residents of a residential building or visitors to a shopping center. We manufacture models with different performance characteristics, using a wide range of modern finishing materials, which allows us to achieve the maximum compliance of the parameters of each product with the goals of our customers.

Vinyl leather samples
Artificial leather is one of the most accessible economy-class finishing materials, which allows you to create neat, varied surfaces in texture, helping to improve the appearance of double-leaf metal entrance doors. Thanks to modern technologies, vinyl artificial leather is in no way inferior to genuine leather in terms of performance or exterior, and models decorated with such a coating fit perfectly into the interior of both residential and office premises.

Powder Coating Samples
Powder coating resistant to mechanical damage is not just a means for painting the metal surface of a double-leaf door, but also a significant factor in reducing the likelihood of corrosion. Models with such a coating can be installed directly on the street, as powder paint is water-repellent and frost-resistant. At the same time, the cost of such a finish is one of the lowest, which allows it to be used in the production of country, technical, vestibule doors, for which not so much aesthetic appeal is important as practicality and durability.
Powder paint is applied to a metal surface by spraying, after which the surface is heated to melt the particles of steel chips that are part of the paint. This method of processing reduces the risk of powder coating peeling during operation, significantly extending its service life in any, even the most extreme conditions. In our catalog you can choose the texture and color of the paint at your discretion, and we guarantee that the operational properties of the coating meet the highest quality standards.
MDF color samples
MDF has found wide application in the production of decorated models. With its use, the metal double-leaf door acquires an original appearance, thanks to which it perfectly complements the interior and creates a cozy atmosphere in the house. In the manufacture of MDF, environmentally friendly materials and protective coatings are used, and the variety of exterior design options opens up broad prospects for creating aesthetic and functional door structures. The high density of the MDF board helps to reduce the thermal conductivity of the material, so that the house retains heat.
We offer a wide range of decorative coatings based on MDF, which in appearance imitate such popular tree species as beech, oak, pine, ash. A wide range of shades, from light to dark, allows you to choose a decorative coating that elegantly complements any interior. MDF has earned recognition among our customers due to its strength, durability, pronounced heat and sound insulation qualities, and our capabilities in the decorative design of products allow us to create the most original models of double doors that will not leave our customers indifferent.
Solid wood samples
A two-leaf door can become an elite class product if such material as solid wood is used in its decorative finish. Natural wood, in addition to high environmental performance, has natural strength, reliability and durability. But most of all, our customers appreciate the wood for its beauty, natural wood grain, which is simply impossible to repeat. Modern methods of processing wood raw materials make it possible to emphasize the artistic appeal of age rings, the texture of wood of such species as oak, beech, ash. At the same time, coatings protect the tree from deformation, which may occur under the influence of external factors.

Before visiting the showroom of a door selling company, so that when contacting a manager you don’t “float” too much in an extraordinary definition, it would be nice to figure out the meaning of very common terms on your own. Quite unusual names of doors can become a bone of contention for an ordinary client: “single-leaf” and “double-leaf”. What is it and what is the difference between these theses?
The difference between the structures is in the number of panels (leaves) that the above door systems are equipped with. You can get acquainted with what constitutes a door leaf in our previous publication, but in this one we will analyze the specifics of single-leaf and double-leaf solutions, their disadvantages and advantages, and also consider the conditions for selecting the most optimal option for living space.
single leaf door
Single leaf doors
It is a structure equipped with only one sash. Single-floor systems are by far the most popular in the domestic market of similar products, both in the form of entrance doors and as internal doors. Designed for installation in openings, the dimensions of which do not go beyond the typical ones (no more than 0.9 m). If the room has openings of decent size, then in this case another option is good, the specifics of which we will analyze a little lower.
Double door and its types
Double wooden door
A double door is mainly used for insertion into rather large openings, as it includes two panels at once. The width of any of them reaches one and a half meters. The advantages of installing double-leaf doors are understandable, they: allow you to organize a free passage, visually improve the atmosphere in the room. Double-leaf systems have several options that allow you to make good use of the free space of the doorway. Let's specify their types:
- equal field;
- unequal;
- One and a half.
In the first version, the dimensions equal field valves coincide, and their placement is symmetrical relative to each other.
In another design, in unequal, the width of one sash exceeds the width of the other, and the distance between the jambs of the opening must be at least 1.4 meters.
The third type of double doors - one and a half. it is considered a subspecies of unequal (valve also 2 pieces) and differs from them only in that one valve is twice as large as the other. The smaller of them, in general, is constantly located in the closed state and opens only when necessary.
The installation of double-leaf doors in the living area is in many cases made at the entrance to the guest room, since it is in this room that countless guests very often gather.
Which is better single door or double door?
When choosing the right option, you need to take into account door opening features unambiguous space. With an opening width of more than 90 cm, it is proposed to install a system with either 2 real leaves or one and a half door system. This limitation is caused, first of all, by the ability to hold the weight load of the structure with standard hinges. With a strong desire, it is possible to install a single-leaf door in a wide opening, but then it will be necessary to stock up on reinforced hinges designed to supply the operation of a large mass door.
Door type. In a small apartment, or in a small privatized house, it would be better to use swing doors. If housing has ultra-wide openings, then in this case, the use of sliding systems will be a wonderful choice.
Material. As a rule, there are no restrictions on the material from which single-leaf or double-leaf doors must consist. You can use structures made of wood, MDF, using lamination technology. Veneered doors will also be an ideal choice, both for living space and for a country house.
