Do-it-yourself installation of dobors on interior doors. How to install an interior door: how to assemble a box, installing extensions How to put extensions on a toilet door

The installation of the door leaf often involves the design of slopes in order to decorate and level them. The best solution to this problem are extensions that are installed on the wall near the box. These structures are small planks of wood or plastic. Before installing such products, you should find out the features of installing extensions on the door. This will simplify and speed up all installation operations.

The need for extras: the pros and cons

Dobors are small planks or boards that are attached to the slopes. They are used only on openings that have a significant width, and the box itself is not able to close them. Technically, these elements are not mandatory attributes of an entrance or interior door. You can do fine without them, but at the same time you will need to form a wide slope, which is not always convenient and practical.

Door extensions have several advantages over other finishing methods:

Possibility of installation on an uneven surface. Therefore, extensions exclude additional wall decoration, which reduces the cost of materials.
High-quality protection against pollution.
High mechanical strength. This is especially true for products made of natural wood, from which extensions are most often made.
The strips installed on the slopes additionally strengthen the door frame, preventing it from loosening or warping.
Versatility. Dobors today are produced in various thicknesses and widths, which allows them to be used for finishing almost any type of slopes. This is especially true of telescopic models that can be sewn together like a wooden lining.
Variety of designs. Designs are made from various materials, which are designed for certain style directions.

Mounting methods

Installing door dobors involves fixing them to the wall. This process is relatively simple and can be done in several basic ways:

Fastening directly when installing the door frame. In this case, the additional board is attached directly to the door frame. Various methods can be used for this. The easiest option is to knock them together using an inner board that attaches to the extension and box. It is important during installation to align the planes of both elements in order to obtain a flat surface. But if the slopes have significant differences, then without certain skills it will be difficult to fit the elements very evenly with minimal damage.

To hide the joint between the box and the dobor, a thorn-groove type connection is cut out at their ends. In this case, the board goes inside the door frame, which hides it under itself. This option is more common, as it allows you to get a beautiful and decorative surface.

Similar grooves today are complemented by the extensions themselves at each of the ends. This allows you to combine them into a more aesthetic system. But for metal doors, it is impossible to make such a connection after installing the box. This is due to the fact that it is technically unrealistic to form a groove in the metal using a milling cutter.

How to do it yourself?

Dobors are ordinary planks or boards that perform a decorative function. Therefore, you can make them yourself from various materials. Often they are formed from natural boards of small thickness or sheet products (chipboard, plywood, etc.).

The process of making dobor at home can be divided into several successive stages:

Initially, measurements of the opening are carried out. It is important to measure the slopes in different places in order to eliminate inaccuracies in dimensions. This procedure must be carried out for each side of the slope separately.
Based on the data obtained, a blank should be made. To do this, the dimensions of the future addition are applied to the board. Please note that it is best to provide a small margin so that no gaps form at the joints after installation. When the markup is ready, the board is cut into extensions. It is better to perform such operations with a circular saw, as it will provide a more even and high-quality cut.
The procedure is completed with fitting and trimming. If the board is slightly larger, then you should align the ends with an electric planer. To give the extension a unique design, the wood must be sanded and painted with stain or varnish. If laminated chipboard is used, then you need to take care of closing the ends with special tapes. They are glued to the material with an iron or a special hair dryer.

The manufacture of extensions allows not only to save money, but also to get a durable system that will be adapted to specific operating conditions.

How to install correctly?

Installation of door extensions is a simple operation, which, if desired, can be performed independently. But before installing such elements, it is advisable to read the instructions for their fastening. This will allow you to deliver them much faster and better.

Required Tools

Installation of extensions is an operation that requires a minimum amount of skills. But to get a quality result, you should use an auxiliary tool, including:

Hand or circular saw. The best option would be a grinder with a special circle for wood or a jigsaw. It is advisable to use saws with small teeth to get a smooth joint without burrs.
Milling machine. With its help, grooves are formed for joining the box and the additional board. Please note that installation can be carried out without this operation. But it is impossible to get accurate and inconspicuous ends without it.
Clamps. These mechanisms are used to fix the grinder to the chair. This will allow you to get a mini circular saw that will make it easier to trim the extension in the right place.
Pencil and a long line.

To optimize the work, you will also need a long table or several stools. They are used as supports on which boards are laid during processing.

How to count?

Installation of extensions always begins with measuring the thickness of the wall. The choice of the type and quantity of consumables depends on this parameter.

Initially, you need to get the width of the free space on the wall near the box. Measurements are taken with a ruler or a corner. The latter option is more accurate, since it is necessary to take into account the angle between the door frame and the board. It is desirable to know the width around the entire perimeter of the opening.
The next step is to measure the thickness of the door frame. This is necessary in order to select the appropriate extension, under which the minimum number of supporting elements will need to be placed.
The procedure ends with the calculation of the number of additions. This takes into account not only the width of the board and the opening, but also their height. It is advisable to take these parameters with a small margin, so that you can then adjust the canvas to the dimensions of the opening. Please note that all extensions on the market have standard sizes. Therefore, when choosing, focus on them.

What can be used instead of supplements?

Dobors are factory-type products that are produced with certain technical parameters. But no one bothers to replace finished products with improvised materials that every owner can find:

Solid board. The best option for making dobor. The material perfectly withstands high loads, and is also strong and durable. In this case, it is possible to use various types of wood for the manufacture of the structure. This will allow you to adapt the final product to the style of the frame and door leaf.
MDF. Products made from wood shavings that are used to make doors. Sheets of this material are also great for extensions. But the substance resists moisture very poorly, so such elements can only be installed indoors with minimal humidity.
Chipboard and fiberboard. Sheets from wood waste, which can be adapted for extensions. Working with them is quite easy, but at the same time they are also afraid of moisture, which limits their use.
Plywood. There are several types of such a substance that is moisture resistant. Plywood is the best option for the manufacture of extensions, as it has an optimal price-quality ratio.

If you do not have these materials, you can make an addition from scraps of plastic lining. Although it is not so strong, it is very easy to cut and is not afraid of moisture.

How to increase?

There are situations when the width of one standard extension is not enough to close the doorway. The solution to this problem is only the extension of the canvas.

This process consists of several successive steps:

Initially, additional boards are installed near the box itself. It is important to fix them qualitatively and evenly.
After that, a second row of material is applied to them, which will already protrude slightly beyond the edge of the wall. This will allow marking along the entire length of the board. An alternative option is to measure an unclosed piece of slope with the subsequent transfer of dimensions to a new workpiece.
When the markup is done, you need to saw off the extension. Please note that cutting is only done from the side that does not fit with the previous board. This is important when telescopic types of coatings are used for building, as they are initially equipped with grooved joints.

When direct extensions are applied, the side of their trimming does not matter. The main thing is that when docking they form a minimum gap.

Installation

The algorithm for installing extensions consists of the following sequential actions:

Initially, all measurements are taken and the dimensions of all elements are adjusted. It is important that the joints of the boards are with minimal gaps, as this will not only not be beautiful, but will also lead to the formation of drafts.
At this stage, the board is adjusted to the wall. This process involves aligning it in the same plane with the door frame. If the slope is uneven, then for this, wooden planks of various thicknesses are placed under the extension. They should be attached to the wall with screws and dowels.

When the slopes are at an angle, then it is advisable not to align them parallel to the box, but to form them with a slight slope. In this case, the angle should be the same on both sides of the opening.

The procedure ends with the installation and finishing of the extensions. To close the ends, platbands are placed on the outside, which are also made of the same material.

And you need to quickly solve it, try to make extensions for the front doors with your own hands. They can be made from different materials, and it will take not so much time.

It is very easy to make dobors on your own

Types of extensions

First you need to figure out what the door extensions are. When a situation may arise when the width of the hole is not large enough to completely cover the wall. Naturally, leaving a bare section of the wall is unacceptable. What to do in this case?

Here, additional elements come to the rescue, in fact - this is a bar that closes the section of the wall left without cladding, with their help you can compensate for the lack of a narrow box, the door takes on a finished look.

Before you make dobors for entrance or interior doors with your own hands, you need to learn to distinguish between their types. The simplest is a straight plank without a facing edge, it is very easy to make, almost any material is suitable for this, but for the aesthetics of the look, you need to hide the raw end with a casing.

The simplest dobor is an ordinary wooden plank covered with a facing material.

The second type is a kind of modification of the previous one. There is no difference in the design itself, the difference is that the end cut is sealed with an edge. This not only positively affects the appearance of the product, but also protects the material from moisture penetration, which is especially important for chipboard and MDF.

More perfect is distinguished by the presence of an edge on the end side

The most difficult is the telescopic extension, its peculiarity is that the bar has special protrusions and recesses that allow it to fit perfectly with other elements of the door system: the frame and trim. The width is regulated by the degree of deepening into the grooves. To make such a bar you need patience and an additional tool.

The telescopic door extension has a special design

If you do not have experience in carpentry, it is better to limit yourself to the first two types.

Buy ready-made or make your own

What will be more profitable in the end: buy ready-made extensions or make them yourself? This largely depends on the front door itself. Most models are made of steel, and in appearance imitate natural wood. In this case, you can make extras yourself. The same applies to wooden doors.

Usually door extensions come with doors.

If the metal door has a complex frame made of the same material, it may be better to purchase ready-made extensions, they will blend perfectly with the system and will not spoil the overall look. If your qualifications are not enough to make telescopic extensions, then it is better to abandon the idea of \u200b\u200bmanufacturing yourself, as ordinary ones can spoil the look of an expensive door. In addition, they can be ordered from door manufacturers complete with a box, while they will be identical in color to all other design details.

materials

Of course, far from everyone will be able to make metal extensions on their own, mainly for this purpose they use:

tree,
plastic.

The main materials for the manufacture of extensions

Tree is the most environmentally friendly material, but wood can deteriorate under adverse operating conditions, so it requires additional processing, which also requires effort and money.

MDF most often used for arranging various structures. In industrial models, between two thin sheets, the inside is filled with cellular material, in home-made ones it is often an ordinary piece of MDF.

Chipboard worse in quality than previous samples. If we are talking about an internal entrance door to an apartment, in principle, you can use it, especially since the cost of chipboard is low.

Plastic can also be used for arranging extensions, however, ordinary cheap material will not work, you need high-strength plastic, preferably reinforced with metal.

MDF door frames are the most sought-after parts in their segment - they last a long time and have a presentable appearance

Manufacturing instructions

How to make dobor on the front door with your own hands? Consider a simple option that every home master will be able to do - wood extensions.

Wood is the best option for self-made extensions

The first step is to measure the width of the wall, which must be closed with an extension. We take a bar of suitable width, lining is perfect for this purpose. Please note that the extension should slightly go under the edge of the box, so the sides need to be slightly cut at an angle to get a neat, even chamfer. Bring the surface to perfect smoothness, use a grinder or zero sandpaper for this.

Neat smooth chamfer looks very aesthetically pleasing

To extend the service life, the wood must be treated with antiseptic impregnation, it will protect the extensions from mold, fungus, and insects.

Then you need to paint the planks with stain, you need to select its shade in the color of the door so that the difference between the elements of the box and the canvas is minimized. After drying, the extensions must be opened with varnish, this should be done in two layers to ensure reliable protection from moisture.

Wooden planks must be opened with stain

If you decide to make extensions from MDF or chipboard, the process is greatly facilitated - you just need to cut the strips of the required width and veneer the sections, for this they use an adhesive-based PVC edge. To fasten it, use a heated iron, as under the influence of high temperature the glue softens and securely fastens the edge to the surface, so that the ends will be reliably protected from moisture and shock.

The variety of colors of PVC edges is simply huge.

Installation

Making slats is only part of the task, then you need to put it in the right place. It is best to start the installation from the upper horizontal bar, after its installation it will be easier to adjust the length of the side elements.

Entrance door extensions, if properly selected, are installed quickly and without any difficulty.

Attachments can be attached in a number of ways. Telescopic are installed in special grooves and snap into place on the lock. But direct extensions can be planted on liquid nails, but this method is far from always suitable, especially if the wall surface is uneven.

Scheme of installation of simple and telescopic extensions

Most often, homemade dobors are fixed with self-tapping screws. First, you need to outline the places for future fasteners and drill holes, then the extreme self-tapping screws are screwed and then the central one. After the location of the extensions is planned, you can begin to strengthen the structure, for this, a few more screws are twisted. Holes and caps can be masked with furniture plugs or with putty to match the material. Now your front door is ready!

Mostly all doors that are manufactured in specialized factories are designed for a certain wall thickness. It is in many cases of the order of 70 or 80 mm. But what about the owners of country or ordinary private houses? Their walls are often much thicker than apartment options.

In this case, you can finish the opening with sheets of drywall or do it even easier - apply the installation of an extension to interior doors. The method is simple and requires much less time and effort to implement. Some homeowners plaster openings in places where there is no box. But, nevertheless, the method of installing extensions is less time-consuming and more effective. Therefore, you need to carefully figure out how to fix the extension correctly.

Dobors are two racks located in a vertical position, and one horizontal bar. It is located at the top of the opening. Thus, the finished design increases the box itself. Among the commonly used materials for the manufacture of structures, the most popular are fiberboard, solid wood and MDF. They are durable and affordable in their price range.

Measurement and preparatory work

The installation of extensions is necessary first of all in order to securely fix the platbands. It is possible to make the correct fixation of the platbands if the products are placed end-to-end to the plane of the wall. It is best to take measurements with the box assembled and installed. After that, the installation of extensions is already carried out.

Initially, you should put ruler on the platform of the box and keep it strictly perpendicular to the wall. It is necessary to determine the dimensions of the upper and lower parts of the product. At the same time, the width of one extension in different parts may differ, since the walls are almost always imperfect. All data should be entered on paper so as not to confuse the parameters of the product.

Many experienced professionals use a more accurate method. Measurement of all additions is made by means of square and flat rail. The first fixture is installed in the seat, and the second is applied to the plane of the wall. Where the square intersects with the rail and there will be a width indicator. The size of each slope must be carefully checked, since an error can be made at any stage.

After the manipulations, proceed to cut the board. This is easy to do with a hand saw. A jigsaw and a stationary machine are also well suited, provided they are available.

Installation

Installing dobors on the interior door with your own hands is quite simple. To do this, you need to decide, first of all, with the type of box. They are:

with groove;
without groove.

The first option is the easiest. It has everything to safely carry out the installation of extensions. The versatility of the presence of the groove is that it allows you to adjust the position of the extension. And also this device saves a lot of time. By adjusting the bar, it can be immediately fixed to the wall.

Self-tapping installation

The first thing to do is to drill a hole under the screw. As a rule, MDF boards, from which blanks are most often made, are approximately 10 mm in thickness. This means that the drill must have a maximum diameter of 9 mm. In order to more accurately and reliably mount extensions on the interior door, the diameters of the drill and the heads of the screws must match.

Directly, the screws are chosen so long that they literally go a little into the canvas of the box. If the products are too long, the wood will crack. A prerequisite is the use of wood drills. They are characterized by the presence of special protrusions in the form of needles. Such products are capable of accurately centering holes.

When the tool is selected, we drill a hole for the self-tapping screw. In this case, you need to choose not a perpendicular direction, but set the drill at an angle. This method will allow you to fix an additional element to the central part of the door frame.

The vertical racks are screwed first with self-tapping screws. After fixing them, proceed to the installation of a horizontal bar.

Installation on carnations

Another very effective way to install a door extension is the method of using carnations.

For installation, you will need to drill small holes into which finishing nails will then be hammered.

Critically important - the drilled holes must be less than the length of the nails!

After that, it is necessary to insert the carnations with the sharp side outward, and remove the hats with wire cutters. A mounting bar is often used for driving nails.

When all the fasteners are in place, you can put extensions and gently nail the product, connecting it to the box.

Foam installation

Installing door extensions according to this principle is several times faster than other methods. Products are put in place. After that, they need to be wedged from the inside. Surfaces should be pressed against the door frame. It is possible to fix the opening only after thorough cleaning and mandatory wetting of the surface.

Installation of telescopic extensions

This type of product has its own unique advantages.

It can be tightly fixed in the overall structure.
The surfaces are securely attached to each other.
Connecting the components together is quite simple.
Dobory with this configuration can be shifted either up or down.
It is possible to move them inside and outside the product.
The power reserve of the parts is small, but these millimeters allow you to adjust the position of the extensions as accurately as possible and correct the mistakes that were made during the marking.
Special "adjustment" grooves make the design convenient and easy to install.

Along with the box

The method is to assemble the entire structure before attaching it to the wall. Both the box and the dobors are assembled into one. Additional elements that expand the opening are attached to the door frame. After that, the finished product is fixed.

The following tips will be helpful:

Carnations are used solely to press additional panels to the door frame. They do not keep from shifting.

In the process of drilling holes, a crack can be made on the front side of the product and between the slopes. Therefore, all work must be done carefully.

When choosing interior doors, we want them to have a beautiful aesthetic appearance in addition to practicality. Well-chosen elements and correctly executed installation of extensions on the door will make the room more attractive and comfortable. The article considers the types of products, their features and methods of installation.

Door extensions are designed to create beautiful door portals that will look better and richer. The addition of the box when installing the door is required if there is a gap between the wall and.

In addition, structures are necessary for:

Closing irregularities.
Slope masking.
Strengthening the entire structure of the doorway.
Prevention of distortions of the door frame.

Product types

Dobory on the door - these are additional strips that close the wall in the opening, "getting" its thickness, which lacks the width of the box.

The main types of extensions are presented in the table:

Dobor type	Peculiarities
	This is a strip of laminate or MDF that does not have a facing edge. In this case, the installation of do-it-yourself doors with an extension must be done with great care. A deviation of even two millimeters will reveal the gray raw edge of the part.
	The end of the part is preliminarily closed with an edge tape matched to its tone, which will make small flaws invisible. The price of the edge is very small, it is glued quickly with a conventional iron. This method prevents MDF boards from swelling under the influence of moisture, which is especially important for door blocks installed in bathrooms and kitchens.
	This is the most complex dobor design. Its feature is the presence of special grooves that allow installation without the use of screws and nails. At the same time, the extension fits perfectly with the box and. The width of the element is regulated by the depth of the groove.
	A feature of the combined design is an addition + platband. In appearance, the product is a decorative corner with grooves of great depth. Doors with extensions of this type are installed only when facing a small amount, up to 45 mm.

The advantages of installing extensions are:

High speed finishing process of the doorway.
The room can be quickly given an aesthetically complete look.
The absence of moisture on wood and MDF protects the structure from deformation, peeling of the outer layer of the finishing coating.
Planks hide the joints of the wall with the box.
When moving the sash, vibration on the box leads to cracks in the plaster or wallpaper. Dobory mask this area, as in the photo.

Materials for extensions

In the manufacture of elements, most often used:

Tree. This is an environmentally friendly material, but its disadvantage is that it can deteriorate due to adverse conditions that arise during operation, which requires additional processing.

Plastic. But for the arrangement of extensions, the usual cheap material will not work, it is necessary to choose high-strength plastic, better reinforced with metal.

MDF. Due to the low mechanical strength and instability to moisture, such materials are most often used for arranging interior openings. During installation, cracking of the planks is possible, for example, when hammering nails. Therefore, you must first drill a mounting hole to install the fastener.

Chipboard. It has a lower quality, but can be used to finish the internal front door in the house, has a low cost.

Calculation of the number of elements

Domestic manufacturers, for serial production, produce doors of different widths, 2 meters high, and European sets have a height of 2.1 meters. The platbands, respectively, have the same length.

In this case, the width of the door extensions can vary from 50 to 550 mm, and the thickness is selected according to the thickness of the groove present at the end of the main frame. High-quality extensions made of MDF, solid wood, laminate, usually have a thickness of 10 mm.

Replacing the front door today is a whole range of works. And this requires additional elements such as extensions and platbands. And if earlier the slopes were finished with cement mortar and paint, today such a design move is no longer used. The installation of extensions on the front door, followed by framing with platbands, came to the fore.

Fittings for the door frame

A new material, which is dobor, appeared not so long ago. But without it it is difficult to imagine a modern doorway. Therefore, you should get to know him better.

Purpose

Why do you need an extension for the door block? This element is designed to decorate the opening after the installation of the box. The fact is that manufacturers in the manufacture of a box bar adhere to a standard size in width. And it is somewhat less than the depth of the doorway, where he has to take his place. And to make the framing look more natural, the free space is supplemented with special panels, which are called dobor.

Dobory are intended for facing of slopes of deep doorways

Varieties

Depending on the design project, the following types of extensions can be used:

Wooden;
Metal.

The most common are MDF products, which are most often found both on the shelves of hardware stores and in the apartments of citizens, thus covering the nondescript slope of the doorway. The next in popularity can be called wood products, and only then only the metal type of extensions.

Dobory with MDF platbands

No less popular are polyvinyl chloride extensions. These products are easy to use and maintain, which is why they are increasingly being used to frame doorways.

In addition to the material of manufacture, framing slopes can be divided into three more categories:

With missing edge;
With existing edge;
telescopic view.

Edge options

The edges of the first type of addition do not have processing, but represent the simplest evenly cut edges. They are closed with platbands installed over the ends of this product. The disadvantage of using dobors, on which there is no lining, is the potential fragility due to the penetration of water vapor into the product.

Dobor with an edge has the corresponding processing. This type is much better protected from moisture penetration. Some inconvenience associated with a trim that has machined edges is the need to select the exact size in width. If this is not done, then the edge will have to be cut, which will automatically deprive it of all advantages.

Telescopic extensions are distinguished by the presence of a machined groove and ridge on the side parts. If you need to close a wider slope, you just need to take another product and connect it to another. Some differences in width are also easily eliminated by the usual separation of two parts without losing an attractive appearance. Thus, the decorative element frames the doorway, making it complete and beautiful.

How to make dobors with your own hands?

If it was not possible to buy a set of extensions along with a door block, then you can always make this element with your own hands. And in the case of finishing the house with a tree, such a solution will be optimal.

To perform work, you can choose ordinary planed boards with a thickness of not more than 20 mm. The width is selected based on the depth of the doorway. To eliminate the warping option that constantly haunts natural wood, you can use an MDF or PVC panel. Such materials are well suited for finishing the front door opening both from the outside and from the inside.

The width of the extension depends on the depth of the doorway

Often used panels have a groove and a comb. So that they do not interfere, you should cut off the excess with a jigsaw or hand-held circular saw. For soft material, a chisel is used, which can easily remove any comb. The cut side should be processed to give it a proper look for docking with the casing. The tree is planed with a planer or milling cutter, and PVC panels are simply cut evenly with a clerical knife.

Under the homemade dobor, you can lay a heater, for example, mineral wool. This will save the owners of the apartment from extraneous sounds coming from the landing. This insulation perfectly delays noise, so using it to finish the doorway would be the right decision. In addition to the absence of extraneous sounds, the use of mineral wool will make the front door warmer, because there will be no drafts and cold bridges.

Stain preserves the structure of wood

Ways to install extensions on the front door

Finishing the doorway of the front door can occur in three ways:

due to the door frame;
to be installed on the wall of the opening itself;
mounted on a special frame.

In most cases, the installation of an additional board involves the use of a special groove selected on the box beam. And the main fastening material here is “liquid” nails. Due to the fact that the extension does not carry a load, adhesive fastening will be quite enough.

Self-tapping screws are an alternative to “liquid” nails. They are twisted into a decorative element on the front side. But if it is not hidden with an appropriate overlay, then the appearance of such a finish will not be entirely attractive. In rare cases, nails with a decorative hat are used for fastening. But this option involves the appropriate interior design of the hallway.

Installation of extensions is carried out using liquid nails or self-tapping screws.

Whichever installation method is chosen, the following steps will be performed:

Two side blanks of the same size are cut off;
Mounted on the side slopes of the opening;
The top blank is cut out;
It is installed between the side elements.

This algorithm can be performed in the opposite direction, when the front door opening skin starts from the top element. In this case, the side extensions should take a position between the floor and the top bar. But at any joint, installation is carried out only from the side elements. This is the most correct and convenient option.

In order for the slopes to be as tight as possible, silicone sealant is placed in the groove on the box beam. Next, an extension is inserted into it, fixed in one of the listed ways. Thus, the absence of air movement through the junctions of the blanks and the door block is achieved.

What if there is no groove

Finishing slopes with extensions can be done not only if there is a special groove in the box. This causes some inconvenience in terms of creating a clear and even contour of the opening. But in this case, you can achieve the desired result.

To carry out work on installing extensions on a box without a groove, you must:

measure the depth of the doorway from the edge to the box beam;
sawing wooden blanks for the frame;
install the frame using bars, building level and self-tapping screws;
fasten the extensions to the frame using mounting glue, self-tapping screws or nails.

According to this plan, you can perform future work and get a smooth and beautifully designed doorway.

Fittings for metal doors

Recently it has become very popular. These blocks do not have a special groove for mounting extensions, although there is a clear need for them due to the minimum width of the iron box. And here drywall comes to the rescue.

Dobory on a metal door are installed using drywall

To install extensions in an opening with a metal front door, it is necessary to cut the strips, the length of which is equal to the depth of the slopes. The number of parts depends on the height of the box beam. The frequency of installation should not exceed 30 cm, which allows you to give the finish proper strength. Planks are glued to the wall. If necessary, an additional one is attached to one part so that the level of the walls exactly matches the contour of the door block.

When a kind of frame is ready, the installation of extensions begins. For work, any materials that are available to the owner of the apartment are suitable. Additional strips are attached with a mounting adhesive applied to the inner surface of each element. Upon completion of work, it is necessary to install platbands on a new entrance metal door.

Platbands on the front door

If the extensions are a continuation of the box, filling the slope of the opening, then the platband can be called its completion. And there is also a large selection.

Purpose and varieties

The immediate task facing such an element as the platband is to frame the doorway. These interior elements are decorated with them. Modern door platbands can be divided into the following categories:

flat;
rounded;
curly.

The first option allows docking in any form. But rounded and curly architraves can only be sawn down at an angle of 45 degrees. In this case, it is necessary to have a special device called a miter box.

Figured platbands are sawn at an angle of 45 degrees

In addition to the form, platbands can be divided into:

Monolithic;
With built-in cable channel.

The use of monolithic elements can be considered a classic option for framing doorways. But cable channels began to be placed in platbands in order to “hide” extra wires from prying eyes. These structural elements are made of PVC and consist of two parts. One is attached to a wall or a box, and the other serves as a decorative cover that closes the wires laid inside.

Ways to install platbands on the front door.

Platbands according to the method of fastening can be divided into:

overhead;
Telescopic.

Overhead architraves are installed with fasteners, and telescopic ones with a comb

The first method involves fastening the elements with nails driven through the body of the casing into a box or wall. Other types of fasteners can also be used, which will be hidden under the decorative element.

Telescopic architraves are installed with the help of a special comb inserted into the groove on the extension or extension bar. In this case, you can use glue to fix the part in place more strongly.
