How are double doors

Classic doors with one leaf are compact, simple in design and made of different materials. A more complex option is double doors, which are also called double doors. They have two canvases and are installed in openings from 1.2–1.5 m wide.

Double-leaf doors are more massive than conventional single-leaf designs

The design of double-leaf doors always includes two leaves, as well as accessories, for example, a box, platbands and other necessary parts. Depending on the type of canvases, such doors are divided into the following options:

1. Equal doors. They have flaps of the same size, which are located symmetrically to each other. The door handle can be on one half or on both, depending on the required level of functionality of the door.

   

   Equal doors have two identical leaves with handles

2. Unequal products. The door leaves differ from each other in size, and the total width of the opening is at least 1.4 m. The door handle is most often present on a larger door leaf, the thickness of the leaves is the same.

   

   An unequal door helps to expand the passageway if necessary, which makes this design option convenient

3. One and a half doors. They have a standard leaf and an additional sash, which can be easily opened if necessary. The additional part is fixed at the bottom with a latch.

   

   Unequal doors allow you to expand or make a standard opening

Any design option assumes an opening with a width of more than 1.4 m, into which a box is installed and canvases are hung. The door movement mechanism can be different. For example, conventional swing models are widespread in both residential and office buildings. Folding or sliding structures that have two canvases that open in different directions can be considered bivalve.

Dimensions and standard door sizes

Double-leaf doors are used for installation in openings, the width of which is more than 80–90 cm, typical for conventional single-floor structures. If the opening has large parameters, then only double-wing complexes are optimal, which are convenient for entering the living room, spacious hall, dining room, library, as entrance.

Sliding double doors do not require additional space to open them

There are doors of standard sizes for apartments or houses with a ceiling height of more than 2.7 m. In such cases, doors with parameters 130x230 cm are installed. Manufacturers also produce other options that allow you to select canvases for any opening and ceiling height. The thickness of the box is 4–6 cm for different types of doors. When choosing structures, this parameter is taken into account, that is, the canvas should be less than the width of the opening by 4–5 cm, and in height by 2 or 3 cm.

Table: standard sizes of double doors

Equal flaps (cm)	Unequal sashes (cm)	Blade height (cm)
60 + 60	40 + 60	200
70 + 70	40 + 70	200
80 + 80	40 + 80	200
90 + 90	40 + 90	200

How to determine the parameters of double-leaf doors

You can find out the dimensions of the door leaf by measuring the opening. If the box is to be replaced, then it is removed, the walls are leveled and the height, width and depth of the opening are measured. In the event that the box does not require replacement, you need to select the doors exactly to the color of the platbands and all available parts. Measurement is carried out taking into account the box.

The canvas should be less than the clean opening in width by 3 cm, and in height by 5 cm

Such a measurement technique allows you to determine the general parameters of the canvases, and the subsequent choice depends on the desired type of doors. For example, in equal-field structures, both canvases have the same dimensions, and therefore it is necessary to divide the opening width indicator obtained after measuring by 2. The result is the width of each half of the structure.

Features of door types

Double-leaf doors are presented in different versions, differing not only in the types of doors, but also in other structural elements. When choosing, take into account such features as:

• dimensions;
• appearance;
• quality and material of canvases;
• type of care, practicality of coverage;
• view of the opening mechanism.

Swing doors are convenient for spacious rooms

Manufacturing custom-made double doors from the manufacturer allows you to get the perfect solution for your home. If the choice is made among ready-made structures, then all the features are necessarily taken into account.

Metal entrance doors

For a wide opening in the entrance door area, metal double-leaf structures are ideal. Often such products are custom-made, but there are also ready-made options.

Metal structures can be of any color and design

Metal models often have one wide and one narrow sash. The design of the canvas assumes a metal frame, inside which is a heat-insulating material. On the side of the room there is a laminated panel that covers the insulation and gives the door an aesthetic appearance. The outer sheathing of the canvases is presented in the form of a sheet of metal and does not have chipping, sharp parts, the box is also made of metal.

Double-leaf entrance door allows you to carry bulky items into the room

The device of the active leaf is no different from the design of a conventional single-leaf metal door. The locking mechanism is installed in the reinforced area, and the metal thickness is from 1.2 mm, which makes the blade reliable. At the same time, double-leaf models are more functional than single-leaf options, since they allow you to expand the opening if necessary.

Interior double doors

Double-sided options are more common as interior doors and are installed in the living room, dining room, office spacious premises. They can be made from wood, MDF or chipboard, plastic, glass or several materials.

Double leaf leaves are very convenient and functional when installed in wide openings

Interior designs with two leaves are chosen in the same way as single-door doors, but taking into account the type of doors. Depending on the material, shape and other features, the following options for double door models are distinguished:

1. Hinged double doors. They are two leaves, which are fixed on the hinges of the box and open by moving inward or outward of the room. Canvases can be made of different materials, and one of the classic options is a combination of glass and wood, but all-glass structures of high strength can be installed in offices.

   

   Glass and wood or chipboard allows for a variety of spectacular designs

2. Arched doors with two leaves. An original solution for both home and public spaces. The design includes two canvases, the top of which is rounded in accordance with the shape of the opening. Such doors look spectacular both in a modern interior style and in a space stylized as a medieval setting or in a country style. The choice depends on the material from which the canvases are made. The design can have a rounded insert, while the canvases remain rectangular.

   

   Wide arched doors will add originality and elegance to the room

3. Double doors with glass. A common version, involving canvases equipped with glass inserts. The shape of such decorative elements can be any. Glass parts can be located at the top of the canvas or along its entire height. They are installed in a frame made of wood, chipboard or MDF.

   

   Glass in the doors helps to visually enlarge the space of the room

4. Sliding models. Suitable for small rooms, but when using doors, the walls around the opening should be free for comfortable movement of the canvases. Doors can have a "compartment" mechanism, which implies the movement of the leaves along the rails, and there are also hinged options in which the elements move on the upper bar. Each canvas is moved in the opposite direction from the other, opening the opening.

   

   Sliding structures can slide inside the wall, in which a special cavity is equipped

How to choose accessories for double doors

The choice of accessories depends on the type of door. Details such as movement mechanism, platbands, lock, handle are necessary for different types of structures, and they must be selected in accordance with the parameters, type of doors.

For double-leaf doors, accessories are purchased in larger quantities than for single-leaf doors

To install double-leafed structures, you will need more components than for single-leaf structures. The main details are the following:

1. Doorknobs. They are installed on both sides of the main web in one-and-a-half or unequal versions or on both parts of the structure in an equal-type door. The type of handle is selected depending on the type of construction. For example, for sliding ones, stationary options or brackets are optimal (they do not interact with the lock mechanism), and for swing doors, they are with a pivot or push mechanism, which prevent the door from opening by a draft. The material of the handles can be anything: metal, wood, plastic.

   

   The handles are mounted in the door opening

2. Door lock. It can be mortise, magnetic, overhead or in the form of a simple latch bolt. The most common cut-in option, which requires special holes in the canvas. Other types are easy to install and do not require significant intervention in the structure of the door, for example, a bolt or a patch lock is simply screwed to the door leaf with self-tapping screws in the right place.

   

   Mortise lock kit is already equipped with a handle

3. The movement mechanism of the canvases. It can be presented in the form of door hinges, which are mortise, overhead, corner, screw-in, universal, double-sided or hidden. Split and universal models are suitable for all swing doors, and the screw type requires the elements to be screwed into the frame and door. For sliding structures, a set of guides, rollers, stoppers and other parts with characteristics corresponding to the weight and dimensions of the canvases is purchased. In this case, 2 sets of rollers must be present, since the doors consist of two parts.

   

   Sliding doors are driven by special rollers that move along rails installed at the top of the doorway

4. Platbands. They are not compulsory components and are purchased only for swing structures. These products are planks made of wood, chipboard or MDF, which are installed on the wall near the box.

   

   Door trims must match the color of the leaf

All door components must have a high level of strength, build quality, good technical characteristics and parameters corresponding to the weight and dimensions of the door leaf.

Stages of installation of double doors

The classic option is swing double doors, and therefore the installation steps should be considered using this particular option as an example. Sliding structures are more complex and varied, but the movement mechanism kit has detailed instructions that will help you install the curtains. In any case, the opening must be pre-leveled, all irregularities that can negatively affect the evenness and speed of installation are eliminated.

Before installing any door, align the opening

For installation, you will need a screwdriver, as well as a building level, a tape measure, a hacksaw, screws and wedges. The main stages of work on the installation of double doors are expressed in the following:

1. The door frame must be assembled and adjusted to the dimensions of the opening if the structure has slight deviations. To do this, use a hacksaw with fine teeth, and fix the parts with self-tapping screws and a screwdriver. Then the box is installed in the opening and fixed with wedges. The structure is leveled, the wedges are gradually removed and the cracks are filled with polyurethane foam.

   

   All elements must be carefully fastened together.

2. Three loops are required for one canvas. The marking of their location begins from the top of the door, measuring and stepping back 25 cm. Another 50 cm is measured from this mark - the second loop is placed here, the third loop is attached at a distance of 25 cm from the bottom of the canvas. With a simple pencil, they emphasize the edges of the hinges, apply and align the elements, and then fix them with screws to the edge of the door.

   

   Loops are fixed with self-tapping screws

3. One of the canvases is hung on the box hinges, the evenness and quality of the element's movement are checked. If there are no deviations, then you can fix the second blade, but in case of problems, the flatness of the blade should be adjusted by tightening or loosening the self-tapping screws of the hinges. In the canvas where the lock will be installed, holes should be made in advance, and then the mechanism should be installed.

4. The gaps between the box and the wall are sealed with polyurethane foam, after which the platbands are installed.

   

   Platbands are fixed with nails with small caps

Features of door operation

Caring for double doors does not differ from the operation of single-leaf structures. In the process of using the doors, the following rules should be observed:

• squeaking hinges can be lubricated with grease, WD40, machine oil, gently applying the composition to the hinge area, and remove excess with a napkin;
• a broken lock or handle should be replaced with a new device of the same design;
• the gentle elimination of dirt with furniture care products will help to extend the service life, and for glass products, you can use specialized compounds;
• scratches on the surface of wood or laminated fabrics can be eliminated with a furniture marker, wax, corrector, matched to the color of the product.

Scratches are easy to hide with special furniture products

Do not clean the surface from dirt with hard brushes or wet rags. This could damage the material. Soft sponges and wipes will prevent scratches on surfaces made of any material.
