If you hear the names double-leaf and single-leaf doors for the first time and don’t know what they are, the first thing that probably comes to your mind is the wrong association. In fact, the names come from the word “canvas” and this is where the main differences between these products lie. What exactly are they?
Double-leaf and single-leaf doors differ in the number of leaves
Single door
First you need to understand what a single-leaf door is. At its core, this is the most ordinary door, which consists of one leaf. These are the models that are most often used for arranging the entrance to the apartment and interior openings.
The standard dimensions of a single-floor structure often do not exceed a width of 80 centimeters, and they reach a height of 2 meters. This way it is possible to close a standard opening, for example, in an apartment.
For residential premises small area This perfect option, if you want to add a feeling of luxury or expand the space due to, then it is better to use the second type of product.
Single door options
Double door and its types
More interesting option- double door. Unlike the previous option, this is a more massive type of structure, for the creation of which two canvases are used, each of them has its own width, usually it is about 150-160 cm. This allows you to close a wider opening and give the interior a certain touch of luxury.
There are the following types of double-leaf doors:
- Equal floors - the doors have same sizes and are located symmetrically to each other.
- Unequal - one part of the product has a greater width than the second sash, while the opening width is more than 140 cm.
- One-and-a-half doors are a separate subspecies of double-leaf structures; one leaf is a standard door leaf, and the second - only half of it. Thus, the passage is closed to a comfortable width, and if necessary, the fixed half-leaf can also be opened.
Main types of double doors
The huge advantage of double-leaf doors is that they allow for greater passage through the opening. That is why they are often used at the entrance to public buildings, in shops, hotels, offices, etc. In addition, they look more massive, and therefore give the room a peculiar touch of luxury. By opening both doors, you can free up the opening and temporarily combine the two rooms. This option is suitable, for example, for the living room and hallway or kitchen and dining room.
Which product is better to choose?
What a double-leaf and single-leaf door is is already clear. Now let's figure out how to choose the appropriate type of structure. First of all, you should evaluate the dimensions of the doorway. For standard apartment openings, a regular single-leaf door is suitable, but if the dimensions of the opening exceed 90 cm, you can’t do without a one-and-a-half or two-leaf design.
Double-leaf doors are excellent for arranging entrances to buildings with high traffic. They can also be installed in an apartment, for example, between the living room and hallway or kitchen and dining room, having previously assessed the available space.
If we talk about private houses, both types will be equally good here. Double-leaf models will ideally fit into the decor of a chic mansion and give it even more aristocracy.
It is also necessary to distinguish between two types of structures that can be used in both cases:
- Swinging ones are regular doors on hinges, additional free space will be required for the movement of the canvas.
- Sliding - these are compartment-type models, especially good for openings more than 120 cm wide, both for a single door and for all types of double-leaf products. This also includes “book” or “accordion” type designs.
Types of door opening will help you decide on the right choice
Be sure to pay attention to the material from which the doors are made. For classic style it is better to choose swing wooden crafts with or without stained glass, and for modern - MDF, plastic or glass.
Both types of doors deserve attention. The specific type should be chosen depending on the characteristics of the room and the available space.

At the same time, in swing structures one of the canvases can be fixed in a closed or open position, and the second is constantly in use. Each of the sashes can have absolutely any engineering permissible width.
Based on the principle of location and main functions of the leaves, double-leaf doors can be:
- Entrance, most often made of metal;
- Interior;
- Products special purpose in the form of fire doors.
Entrance double doors
Most often input structures double-floor type is installed in large public buildings. Installation of such doors is possible provided that the opening width exceeds 800 mm. The most common width of the valves is with a total size of 1200 mm. Such designs are justified in office, financial institutions, as well as in recreational areas and shopping complexes.
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 large loads are moved and possible movement Vehicle of various sizes, the total width of the canvases is more than 1700 mm.
Any two-field steel door consists of two main parts: a welded or solid curved frame common to both leaves and two panels of the same or different widths. The main convenience of these structures is the ability to open both one part of the opening with partial overlap, and the entire one, using both sashes.

The canvases can be of a blind type or have partial glazing. At the same time, the location decorative inserts, their shape, size and symmetry in relation to the paired canvas are absolutely not regulated by anything.
The following materials are used for finishing the product:
- Natural wood veneer;
- Laminate;
- MDF sheets;
- Faux leather;
- PVC film;
- Marine plywood, resistant to various weather conditions;
- Plastic;
- Powder coating.
In most cases outer part two-field front door covered with a material that is resistant to various weather conditions and protects the metal from corrosive processes. Inner side products are mostly fulfilled decorative function, so the coating can be absolutely anything.
Interior double doors
Interior 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 is, in most cases, blind, and the wide, frequently used leaf is equipped with various decorative inserts.
Also, quite often, a double-leaf interior door is made of glass. This solution allows you to fill the room with natural light as much as possible and visually significantly enlarges the room. In addition, the following can be used as the main manufacturing material: natural wood, MDF and chipboard boards, plastic profile, metal.

Despite the ability of the door material to withstand high temperatures, fire and smoke, the product has a relatively light weight. This is a significant advantage of the door, since most wide doors are quite heavy.

Double-leaf fire doors are equipped with special linings that ensure tight closure of the doors and, as a result, almost 100% tightness of the product. To ensure high structural reliability, as well as ease of operation, fire doors with two leaves are equipped with separate elements independent fittings.
Fire doors with two leaves are in most cases installed in the following public and private facilities:
- Production workshops;
- Large commercial buildings;
- Warehouses with the need to move large cargo;
- Laboratory premises;
- Offices in large complexes.
The main feature of doors is the ability of the protective layer of filler during prolonged exposure elevated temperatures foam. Thanks to this, not only the tightness of the product increases, but also the shape of the structure is maintained for a long time. Thus, the double-leaf fire door is not subject to jamming or distortion in the event of a fire, which corresponds to the high safety indicators of the product.
