All about the door frame for interior doors. Classification of doors and their components Threshold for an interior door

door block is a door frame with a canvas hung on it. Installed in the opening of stone walls or partitions, such a block protect from decay, in addition, it is fixed, like window blocks, to wooden liners embedded in the slopes of the opening. The threshold of most exterior doors, including balcony doors, is somewhat raised. Door block in the opening of the partition installed in the same plane (flush) with one of the surfaces of the fence. Then it is attached to the bars framing the opening, or to wooden liners. The gaps between the box and the partition are closed, and the joint is closed with a casing.

Elements of filling the doorway include: U-shaped door frame with quarters to the strapping office; door leaf hung on the box.

Separate parts and details of doors bear the following names:

- the opening part of the door is called the door leaf;

- a frame installed in a doorway, on which door leafs are hung, is called a door frame;

- to decorate the opening and cover the gap between the box and the partition or wall, platbands are installed around the perimeter of the box;

- the transition from platbands to skirting boards and the floor can be made out with bedside tables;

- to improve the thermal insulation, sound insulation and fire resistance of the door, they arrange a door threshold, which is a special bar in the floor, at the bottom of the doorway;

- to protect the lower part of the door leaf from contamination and damage, a plinth can be used (mainly at external doors);

- door flashings are called bars with a shaped profile, designed to cover the vestibule of double-leaf doors;

- door slabs are called bars with a shaped profile designed to divide the glazed part of the door and strengthen the glass;

- the strapping of the door leaf, with a frame (paneled) solution of the door, are called the main bars, the mullions are the bars that divide the door leaf into parts and serve as a connection between the strappings;

- panels are called separate shields that fill the space between the strappings and mullions;

- door leafs are attached to the box (hung) on hinges;

- door appliances are attached to the canvases: locks, handles, latches (latches), safety chains, etc .;

- to increase the sound and heat-shielding properties of doors, special seals are used.

Figure 8.2 - Components of doors

For the convenience of evacuation, most doors in civil buildings open outward, with the exception of internal and entrance doors to apartments.

Door panels:

-panel, which is a blockboard, lined on the outside with wood-fiber boards, plastic or veneer from valuable wood species. Such door leafs are economical in terms of wood consumption, decorative and widely used in modern construction;

- strapping, made in the form of a wooden frame with glazed filling. Cloths of this design are intended for internal doors;

- lattice, glazed at the top with longitudinal stripes and protected by vertical bars. Such canvases are used for the entrance doors of residential buildings;

- paneled, consisting of a contour strapping, reinforced with a mullion, and panels (filling) made of plywood and plank boards. Such a design of canvases is laborious to manufacture, requires high-quality wood, and therefore in modern construction it is used only for the front doors of public buildings;

-carpentry, made in the form of a board shield on slats or dowels. Doors of this design are arranged in the basement;

- tempered glass with a polished or patterned surface. Such canvases with a thickness of 10-15 mm are intended for the entrance doors of public buildings.

The interior door is a complex structure, each element of which has its own name. We invite you to familiarize yourself with the basic concepts that will help you navigate the world of professional terms - what the door consists of, and how each part of it is called.

Components and some elements of door decor

The door leaf is the movable opening part of the door. The canvas is attached in two ways: to the box on hinges (swing) or to the sliding rail on rollers (sliding). The door may consist of one, two or more door panels of a frame or panel structure. The frame canvas is lighter in weight (the internal cavities are filled with chipboard, MDF, solid wood bars, honeycomb filler) and has more options for decorating.

- frame U-shaped structure, on which the door leaf is hung. This is the fixed part of the door block, which is firmly fixed in the walls of the doorway.

The strapping of the door leaf of the frame structure is coniferous wood bars located along the inner perimeter of the door.

Middle bars - bars that serve as a connection between the harnesses. The interior space of the canvas is divided into sections into which panels or glazing are installed.

Panels - parts of the door leaf, which close the space between the strapping and mullions. Depending on the type of connection with strapping, they are divided into smooth, with a frame, floating, with a figurine, with layouts.

Kalyovka is a decorative (shaped) profile that separates the door leaf into parts. Mold frames a panel or glass.

Layouts - slats with a relief profile, which reinforce panels or glass. They also serve as a decorative element on simple smooth surfaces of the door leaf.

Frame (glazing bead) - a thin rail with which panels or glass are attached to the strapping. Creates a reliable framework for fastening of elements of a cloth.

A sham strip (door flashing) is a rail with a relief profile, which closes the porch (gap, gap between the leaves) of double-leaf doors.

Door slabs - small bars with a shaped profile, which divide the glazed part of the door into separate segments. Strengthen and make stronger the entire structure of the canvas.

Plinth - a horizontally fixed long panel, which closes the mounting seams and cavities between the floor and the wall.

- overhead strips covering the joints and gaps between the door frame and the wall. They serve as a decorative element of the door frame, they are flat, rounded, figured, telescopic and on a key. The dimensions and materials of the platbands depend on the type of door leaf.

Threshold - a special bar installed at the bottom of the doorway. Serves to improve heat and sound insulation, fire resistance of the door. The threshold covers the joint between the floors in adjacent rooms, and also levels the difference between the floors of different levels.

Seals - gaskets of tubular or more complex section installed around the perimeter of the door frame. Reduce heat loss, perform the functions of noise and dust insulation.

One of the common options for visually increasing the space in a room is the dismantling of interior doors. This solution allows you to visually expand the premises, create a single space in the interior. In this case, an important task arises - finishing the doorway. In this article, we have collected the most popular and non-trivial ways to solve this issue.

Opening preparation

The process of preparing the work surface varies due to the materials chosen as finishing.

Types of finishing materials

The choice of materials for finishing the doorway in the construction market is extensive, there are options for both economy class and expensive alternatives. It all depends directly on the needs, desires and capabilities of buyers, as well as several important aspects:

you should not save on the quantity and quality of fasteners (for example, if you make a crate of wooden bars, then you need to look at them for mold, rot and large cracks);
when buying materials packaged in different boxes, you should check the batches of deliveries, if they differ, then the shade of the contents may also differ;
the durability of the material, its ability to withstand daily contact with various external influences - this is what all masters should think about first of all.

Using the most popular options for finishing a doorway as an example, let's take a closer look at the workflow for each of them.

Plaster

This option can be called the most popular due to the simplicity of work and the practicality of using the finishing material.

The only thing to take care of before starting finishing is to cover the floor with film or newspapers so as not to damage or contaminate the surface.

Work begins with the preparation of the opening: cleaning from old materials and priming the surface.
Installation of beacons (should mix a little solution and fix the perforated corners on the walls, exposing them to the building level).
A masonry reinforcing mesh is attached between the corners.
The building mixture is prepared in the required quantity.
Using several spatulas, the mixture is applied to the walls in a chaotic manner, after which, using the rule, it is smoothed over the surface.

It is important to remember that the thickness of one layer should not exceed 2 cm, otherwise voids or cracks may form, and this will adversely affect the durability of the finish.

If everything is observed, it remains to wait until the surface dries, and you can proceed to finishing: painting, wallpapering or applying decorative mixtures.

Clinker tiles, mosaic

This material is intended for cladding a variety of areas of a residential building, including a doorway. There are no special laying rules, options are offered depending on the interior design:

Facing a doorway with tiles or mosaics does not require special tools or special skills, the workflow consists of step-by-step actions:

after the surfaces are cleaned and plastered, it is necessary to apply markings, according to which the tile will be located in the doorway;
prepare a special glue (liquid nails are used only in cases where the surface is perfectly flat);
apply glue with a spatula to the back of the tile, spread it over the surface, remove excess;
press the tile against the wall and hold for a few seconds, applying force.

In order for the products to be fixed evenly on the surface of the opening, plastic glazing beads should be prepared in advance, which are inserted into the seams between the tiles. It is removed after the adhesive mass has hardened, not earlier than after 24 hours.

It is very important - if the adhesive gets on the surface of the tile, it should be removed immediately, since the hardened mass is very difficult to remove.

When the opening is completely ennobled, the seams between the tiles are sealed with special grouts, the color of which is matched to the tone of the walls or finishing materials.

Decorative rock

Another option that is used as an alternative to clinker tiles is decorative stone. It has several advantages over other finishing materials:

exact imitation of natural rocks, while there are a lot of varieties of textures: marble, limestone, jasper, brick, wood cut and many others.
tolerates high humidity without consequences;
easy to care for, because does not require the use of special tools to remove dirt from the surface;
resistant to mechanical damage, subject to the rules of laying.

The installation process is very similar to laying clinker tiles, but there are a few important points that you should not forget:

depending on the thickness, the weight of the products may vary, which may increase the consumption of the adhesive mass;
when purchasing a finishing material, inspect a few pieces from the back, if there are many pores on the surface, they have a low density, which will affect the strength of the stone.

This finishing material is found in two types:

Natural. It is made from natural rocks, crushed into crumbs. Such products are distinguished by their weight and strength under direct mechanical influences.
Artificial. Its basis is gypsum, to which dyes and polymers are added. The main advantage is the low price, which fluctuates around 300-800 rubles per square meter.

Wood panels, MDF

An equally popular option for finishing door slopes are wooden or MDF panels laminated to look like wood, which harmoniously fit into the classic style. The benefits include:

aesthetics;
durability;
no visible defects in contact with water.

The process of installing wood or MDF panels will require you to purchase additional materials - wooden slats that will be used as a crate:

The slats are cut to fit the width of the opening and fastened with dowels and self-tapping screws to the walls.
The panels are also adjusted to the opening with a slight indentation, which is hidden using the end corner.
The start panel is fixed with finishing nails.
All subsequent panels are fastened through a tenon groove (connection system present on the products).
From the end, the structure is closed with a side panel - a casing, which is attached to nails to the crate or end corner.

Photo instruction for finishing the opening with MDF panels

To hide the fasteners, you can use special furniture wax or adhesive plugs, matching them to the color of the panels.

Such a finish will look rich, even if inexpensive MDF panels with a textured pattern under exotic wood were used.

Laminate

Many finishers love laminate for its flexibility, which allows it to be sheathed with this material in almost any openings, corners and nooks and crannies found in residential premises. The only thing to worry about is that it does not tolerate moisture well, and after contact with water, swelling can form on the ends of the products, and such defects are not eliminated.

The laminate is fastened with self-tapping screws to the crate in the same way as finishing with PVC or MDF panels.

If the walls are relatively even, then you can use liquid nails and spacers, which will press the material against the surface of the walls for several hours.

Stucco - plaster and polyurethane foam

One of the most interesting, but in its own way capricious materials is stucco. Using it in the interior for finishing the doorway, one should maintain a single concept of the overall design, fit into the style that is inherent in columns, pilasters with capitals and other similar decorative elements.

Stucco on the opening should be combined with other interior elements, such as floor and ceiling plinths

There are two types of stucco on the construction market:

Gypsum. Without it, it is impossible to imagine the interiors of country houses made in the Venetian or classical style. But in small apartments, such products seem too bulky, interior openings narrow not only visually, but also in fact. Plus, gypsum is a very heavy and brittle material; under mechanical stress, it will not last long.
Artificial, or rather polyurethane, is an affordable analogue of gypsum.

The advantages of polyurethane foam decor can also include:

ease of construction;
ease of installation: products are easily cut with a clerical knife and attached to liquid nails;
a variety of ready-made forms;
The polyurethane surface is suitable for painting.

The stucco molding looks perfect framed by a doorway with an arch, especially if the width allows you to erect monolithic column supports along the edges.

doorway shapes

Finishing openings between rooms without a door is difficult not only in the choice of material used, but also in what shape this very opening will be.

The solution of this issue will affect the harmony of the transition between rooms, the lighting of the premises, the combination of styles in the interior and the practicality of moving.

Rectangular

The most common option is rectangular. Such an opening remains immediately after dismantling the door frame and it has its advantages:

suitable for all finishing materials;
construction of additional structures is not required;
clearly delimits two living spaces, for example, a balcony and a kitchen, while visually expanding both;
great for modern interior design styles.

A wide rectangular opening allows you to use slopes as niches for interior items

Arched

The arch has an interesting ability: in rooms with low ceilings, it visually raises them, and in cases with high ones, on the contrary, lowers them. At the same time, the wider the opening in the form of an arch, the lower the ceiling appears.

Many prefer this option for its softness, lack of sharp corners, which makes the transitions between rooms more invisible. The arch fits perfectly when entering the hall, if it is wide enough, the movement between the rooms will be imperceptible.

The absence of a massive decor of the doorway emphasizes the beauty and complexity of the rest of the interior.

A nice addition are ready-made solutions - arched type extensions, prepared for installation in doorways.

The extensions and the developed edging of the opening emphasize the complex shape of the opening, making it a visual accent.

Trapezoidal

This form is used very rarely, this is due to the fact that in small areas such a solution has the opposite effect: the room does not expand, and the ceiling visually lowers. Especially in cases where the upper horizontal part of the trapezoid is too narrow. It may seem that when making the opening they wanted to make an arch, but they did not have enough strength and skills.

Such an opening looks good when it matches the shape of the room behind it, as in this picture.

The polygon will fit well into the transition, where double-leaf interior doors were planned or installed. With the help of drywall, you can easily and effortlessly turn a rectangular gap into a smooth trapezoid, fixing it at the corners of the opening.

Asymmetric

The doorway, which embodies the fantasies of the owners of the living quarters, is an asymmetric shape. Designers love her for the opportunity to implement the most amazing solutions. The opening ceases to be the border of two rooms, it turns into an apartment decoration, into an element that attracts the eye and emphasizes a given style.

Asymmetric opening - the highlight of any interior

However, here there are nuances that many people forget about and face difficulties in the process of work:

you can’t take on the expansion of the opening without creating a project that will take into account all the possibilities of load-bearing walls and ceilings;
sharp corners and sharp shapes have a negative psychological impact on others; it is necessary to minimize the presence of irritating factors so that the ennobled openings serve as its advantage, and not its disadvantage.

Curtain decoration

A simple but very interesting option for decorating a doorway with curtains is a look into the past. A few decades ago, this is how people demarcated the living space, decorating the passageway with wooden or fabric curtains. The desired effect was achieved: the boundaries of the room were visually outlined, while the space was not closed.

Curtain - a simple and effective solution

But such solutions are popular even now, only the variety of forms and materials has become much greater. The most commonly used bamboo sticks are very durable and make a pleasant sound when colliding with each other. You can paint them yourself in the desired shade or choose a ready-made version for your interior.

You can use curtains anywhere, even on the border of the hallway with the bathroom, though it's a little intimate, but if the owners of the home are interested in this option, then why not experiment.

Doorways in walls and partitions are filled with door frames with door panels hung on them. Structurally, the door frame, like the window frame, is a frame, the dimensions of the elements of which depend on the location of the doors and their type. When the doors are hinged, the boxes have quarters on the inner surface measuring 15x40 mm for the porch with door leafs.

Door frames in the openings of stone walls, which, as a rule, have quarters, are fastened with nails or ruffs driven into special wooden inserts in the masonry of the walls of the openings or directly into the brickwork of the walls. Before installation in the openings of stone walls, door frames are antiseptic and upholstered with roofing felt or roofing felt, the gaps between the wall and the frame are sealed with caulking, and the slopes are plastered with cement-sand mortar (Fig. 25.13.).

In partitions, door frames are attached to the strapping elements in the openings, and the gaps between the partition and the frame are closed with platbands. The platbands below the floor can end with bedside tables - short profiled strips that close the gaps between the floor and the platbands (Fig. 25.13.c. and 25.14. a. b.).

To fill doorways in internal walls and partitions in civil buildings of mass construction, as a rule, wooden doors are used, the leaves of which have a thickness of 40 mm, a height of 2000 mm and a width of 600, 700, 800, 900 and 1100 mm (single-leaf doors); as well as a height of 2300 mm and a width of 1200, 1400 and 1800 mm (total width of double doors). For utility rooms, for example, sanitary facilities, it is allowed to use door panels with a thickness of 30 mm and a height of at least 1800 mm (doors to bathrooms, toilets, pantries, etc.).

Entrance doors to the apartment from the landing or corridor have a width of 900 mm with reinforced door leafs and boxes with thresholds, for entering rooms - 800 mm, and for utility rooms

rooms - 600 and 700 mm.

The design of door panels depends on the purpose of the doors and can be shield, paneled or strapping. The panel door leaf consists of a bar frame, which is filled with a solid board of bars or slats, or a frame of bars or slats and covered on both sides with plywood veneer, fiberboard or plastic. Panel sheets can also be without strapping in the form of a solid slab of bars or slats with plywood veneer or fiberboard facing (Fig. 25.14.e.d.e.)

Paneled the door leaf consists of an external vertical and horizontal trim located along the perimeter of the leaf, mullions (intermediate elements) and filling between the trim and mullions, called panels (Fig. 25.14.g.zh.z.i.k.).

Panels they are made of boards, plywood, fibreboard, plastic, while the interior doors are made with single-layer panels, and the entrance doors are multi-layered with a gasket, if necessary, between layers of insulating material. Paneled doors are used in unique buildings, in individual construction, etc.

doors strapping structures have a strapping made of solid wooden elements and filling in the form of flat elements made of plywood, fibreboard, plastic, glass, etc.

For internal entrance doors, door frames with thresholds and blind door panel swing panels with solid filling of panels with wooden bars or slats are used, and for interior doors, panel panels with frame filling and door frames with and without thresholds with the installation of mounting boards can be used, which are attached to the lower ends of the vertical trims of the door frames, while the door leafs can be hinged or swinging. Swinging canvases are hung on door frames using special spring hinges that provide opening in both directions and automatic closing of the canvases (Fig. 25.15.).

Door leaf- This is the movable opening part of the door. The canvas can be frame or panel construction. In the case of a frame structure used to lighten the weight of the canvas and give greater opportunities for decoration, the internal cavities not occupied by the structure are filled with either honeycomb filler or chipboard, MDF, solid wood bars. Usually the canvas is hung with the help of loops on the box, or with the help of rollers on the sliding rail. The door may consist of one, two or more door panels.

door frame- an assembly unit of a door block of a frame structure, designed for hanging canvases and fixedly fixed to the walls of the doorway.

Binding of the door leaf (with a frame solution)
- these are bars, mainly from coniferous wood, located along the perimeter of the door.

middlemen
- bars dividing the inner space of the canvas into sections for the subsequent installation of panels or glass, and serving as a connection between the strapping.

Panels
- shields filling the space between the strappings and mullions. According to the type of connection with the strapping, the panels are divided into smooth, with a frame, floating, with a figurine, with layouts.

Mold
- shaped profile on the edges framing the panel or glass.

Layouts
- these are embossed profile rails attached to the front surfaces of the door leaf and serving to "revive" the appearance of simple smooth surfaces or, at the same time, reinforcing panels or glass.

Frame (or glazing bead)
- an intermediate frame element for attaching a panel or glass to the piping.

Sponges or door trims
- these are embossed profile rails designed to cover the porch of double-leaf doors.

Door slabs
- bars with a shaped profile, designed to divide the glazed part of the door and strengthen the glass, as well as strengthen the entire leaf structure.

Decorative overlays (false slabs)
- overhead decorative profiles glued onto glass or double-glazed windows from the inside or outside and forming a false cover (false cover).

plinth
- a sewn-on narrow panel, with the help of which the assembly seams and cavities that appear between the floor and the wall during the installation of floors are closed.

platbands
- wooden (plastic) profile strips used to frame the doorway and to cover the gaps between the frame and the wall. Platbands are flat, rounded, curly, telescopic and doweled. Their sizes and materials of finishing and manufacturing are also different.

Bedside tables
- the transition from platbands to skirting boards and the floor is made out by bedside tables.

vestibule
- the place of adjunction (connection) of the door leaf with the racks of the door frame. This is a protruding part on the outside of the door leaf or on the inside of the frame, covering the gap between them when the door is closed. The porch is usually included in the design of doors, the hinges of which are located on the vertical side planes of the leaf. The vestibule is most often absent if the hinges installed on the top and bottom of the leaf are used in the door block.

Threshold
- a special bar in the floor, at the bottom of the doorway, which serves to improve thermal insulation, sound insulation, fire resistance of the door, as well as to cover the junction between floors made of different materials in adjacent rooms. It is also applied in case of differences in floor levels in adjoining rooms.

Low tide
- a part designed to remove water and protect the lower parts of windows and balcony doors from moisture penetration. Usually the ebb is installed on the outer side of the lower horizontal profile of the window and is an integral part of it.

Profile
- a measured segment of a product produced by extrusion, with a given shape and cross-sectional dimensions. This technology is usually used for the manufacture of aluminum alloy profiles. These profiles are used in the production of modern window and door frames.

Profile system
- a set (set) of main and additional profiles, forming a complete structural system of door (window) blocks, reflected in the technical documentation for its manufacture, installation and operation.

Seals
- elastic gaskets of a tubular or more complex section, running along the entire perimeter of the window between the frame and the sashes and protecting from cold air, noise and moisture. Seals are also widely used in the production of doors and are installed both in the box to dampen noise when closing the leaf, and in the grooves where the glass is then placed.

Reinforcing insert
- a profile steel element installed in the main chamber of the main profile to absorb operational loads. Panel - a section highlighted by thin profiled frames, a shield made of thin boards, plywood or plastic, covering the gap in the frame of the door leaf.

Doors are massive
Doors of this type are made of various, valuable breeds of a tree. The price for such products, as a rule, is significantly higher than for doors with honeycomb filling, and they weigh more. To emphasize the structure of the tree, the manufacturer paints them with various wood impregnations or simply transparent varnishes. In addition to the decorative function, such processing also plays another role. The door is less susceptible to damage by fungi, mold, insects, and is more resistant to fading in the light. Such doors are also called simply - an array. They can be smooth or paneled, deaf or glass-like, left-handed or right-handed, painted, veneered, laminated, etc.

Doors are semi-massive
Wooden bars between two sheets of MDF in such a door leaf are not located “butt-to-butt”, but at some distance from each other. Otherwise, everything said about massive doors is also true for semi-massive ones.

Doors with honeycomb filling
You must have seen a honeycomb made of wax. Exactly the same honeycombs, only from pressed cardboard, less often from hardboard fill the void inside the door. The frame of the door is made, as a rule, from solid pine, which allows you to embed the lock on one vertical side and fasten the door hinges on the other. The strength of such doors, of course, is inferior to the strength of massive doors, and they are not recommended to be used as entrance doors. But indoors (offices, apartments, houses, etc.) is the most suitable option. And one should not doubt their strength for these purposes. The door leaf with honeycomb filling easily withstands loads up to 80 kg. Just like massive and semi-massive doors, doors with honeycomb filling can be smooth or paneled, deaf or glass-like, left- or right-handed, painted, veneered, laminated, etc. Such doors are also called lightweight.

Paneled doors
The canvas on both sides of these doors is not smooth. Doors have, as a rule, cut-in rectilinear or rounded decorative recesses. They can be: lightweight, massive or semi-massive, under glass or deaf, painted, veneered, laminated, etc.

Doors are smooth
The exact opposite of paneled doors. These doors have a completely smooth surface. Otherwise, everything said for paneled doors is also true for smooth ones.

Doors under glass
Window frames of various configurations are cut into such doors. The buyer can choose the glass according to his taste. Here in the choice he will not experience difficulties. A great variety of them are now offered: - corrugated, matte, stained-glass windows, etc.

Doors are deaf
These doors do not have window frames.

Single door
The usual door, consisting of one leaf.

Swing doors
The door is made up of two panels. These doors are also divided into equal and unequal. For equal-swing swing doors, both canvases are of the same width, for unequal-swing doors, one of the canvases is much narrower, it can also be called widening.

Veneered doors
A veneer is a thin cut from a tree (with a thickness literally like thin cardboard). Various types of trees are used as raw materials. This same veneer is used to glue the door leafs.

Doors laminated
Usually, smooth doors with laminate glued on them, decorated with different types of wood or painted in different colors.

Laminated doors
Pretty much the same as laminate flooring. The only difference is that this coating is less wear-resistant than laminate. True, such doors are cheaper than laminated ones.

Left hand doors
Standing in front of the door, open it with your left hand. Door hinges (in a box), on which the door is hung, are located on the left, a lock with a handle, etc., are built in on the right - the door is left-handed.

Right hand doors
Open the door with your right hand. Door hinges (in a box), on which the door is hung, are located on the right, a lock with a handle, etc., are built in on the left - the door is right-handed.

Doors with a vestibule (with a quarter)
There is also such a thing as a vestibule or a quarter. At the end of the door leaf, on two or more sides, three quarters of the thickness of the door leaf are selected and one quarter is left. Thus, complete with a corresponding door frame, such a closed door has no visible gaps between the frame and the door leaf.

Doors fire-resistant or fire-resistant (fire-retardant)
As the name implies, these doors have special properties and meet the increased requirements for fire resistance and sound insulation. They can be decorated with any of the above materials and colors. But the price for them is correspondingly higher than for non-fire doors.

Door furniture
We are talking about locks, handles, plumbing latches (turn buttons), cylinders (cores) and plugs. Manufacturers go to meet buyers, so the choice here is also very large. Try not to make a mistake in the selection of hardware components and purchase it as a set. Although, now there are certain standards and successful combinations are possible. Oh, and don't forget the door hinges. When choosing them, consider what your door will be - left-handed or right-handed. Some manufacturers already complete their products with mortise locks at the factory.

Door frames, trim
Usually supplied with the door. Both MDF and various types of wood are used as raw materials. There are boxes that are adjustable to the thickness of the walls. They can be painted or decorated with veneer, laminate. The same can be said about the platband.
