Each interior door after installation needs a finishing touch - extensions. This element allows you to give the design a complete look. Dobors are boards that frame the door leaf. They close the gaps that remain after the installation of the door. Even a novice master can install them. To do this, you need to consider the interior doors. detailed instructions will be presented next.
Why are supplements needed?
Many novice masters are interested in how to install an extension on the interior door "Tanganyika", "Terra", "Modern Nika" and other popular models. This is an easy procedure. However, you should be aware of some of the nuances of doing this work.
Why are supplements needed at all? These are decorative boards that frame the door leaf. Two of them are vertical and one is horizontal. They are designed to increase the space that the door frame can cover. It becomes larger, so all the flaws made during the installation of the door become invisible.
Extras are created from different materials. It can be natural wood, MDF, chipboard. Sometimes door manufacturers supply slats along with the door leaf. However, sometimes they are purchased separately. Planks can be of different widths. In a room with thin walls, thin extensions will be appropriate, and in a room with thick partitions, wide ones. This indicator can vary from 8 to 55 cm.
Varieties
There are several types of extensions. They may be without edges. In this case, the ends of the board will not be protected by a layer of decorative film. A simple edging with an edge is protected by a special layer on all sides. There are also telescopic extensions. In their ends there are special grooves with which fixation is made.
The first two types of extensions are straight planks. They have straight cuts. Experts recommend installing extensions with an edge. Such products allow you to close the entire cut. In this case, the door will look nice and neat. If you choose extensions without an edge, there is a chance that they will not completely close the cut.
Many owners are interested in how to install telescopic extensions on interior doors. This is a more modern type of boards. They have a groove with which a tight fastening is made, which does not require the use of additional materials. The dobor is connected to the door frame or platbands without glue.
Installation methods
Do-it-yourself installation of dobors on interior doors can be done different ways. The design forms the letter "P". It can be attached in a variety of ways. You can fix the boards directly to the door frame or to the wall in the opening area. You can also install the strips on the mounting beam, which is located between the vertical sections of the opening and the extensions.
It should be noted that during operation, a high load will not act on the slats. Nevertheless, in order for the extensions to be firmly fixed in place, glue is often used. However, experts advise using self-tapping screws for these purposes.
Fixation with hardware is carried out with front side. Therefore, it is important to deepen their hats. So the fastener will not be visible, will not interfere with the opening and closing of the door leaf. On top of the hats, you need to close them with special plugs to match the extensions or cover them with mastic.
Preparatory work
Having figured out what extensions are, you can choose the best option for your door. It is necessary to determine which option the manufacturer provided for a particular model. It should be noted that the installation of telescopic extensions on interior doors is not always possible. We need grooves in which it will be possible to install the strips.
After choosing the type of extensions, you need to calculate the dimensions for each side. It is especially important to pay attention to their width. Subsequently, it will be impossible to correct this characteristic. Removing the length of the extensions is quite simple.
Next, you need to prepare the surface for installation. Excess foam must be cut off with a knife. Also, all contaminants must be removed from the surface of the base. Otherwise, distortions may appear. Proper preparation surface allows for good adhesion of extensions to it. After that, you can proceed directly to the installation.
What else to consider before installation?
When studying the technology of how to install interior doors yourself with an extension, you should pay attention to the installation of decorative strips. Often beginners make mistakes in the course of such work. Having installed a box for an interior door, they may notice a significant skew. In this case, the addition will not help. You need to pay attention to correction.
If the deviation of the upper bar in the horizontal plane is more than 5% of the total length, it will not be possible to install the extensions correctly. Of course, the master can fit the canvas to such a box. However, the presence of such a defect indicates serious errors made during installation.
To eliminate them, you will need to dismantle the entire structure. It is necessary to find out what exactly led to such a violation. Only by eliminating the error, it will be possible to install extensions. Otherwise, they will not improve the appearance of the door immediately after installation. During operation, they crack and deform. To prevent this situation, you need to pay attention to the exact installation of the structure.
Tools and materials
To perform all the manipulations quickly and correctly, you need to prepare a manual milling machine designed for woodworking. Be sure to prepare a manual parquet (circular) saw. In the course of work, a clamp is required. She should have a soft lining on the bed.
If there is no such material on the instrument, it is quite possible to fit it yourself. This will require several heat shrink tubing. They are put on the tool and heated over gas burner. It is necessary to keep the material at a distance from the flame of about 40-50 cm (not closer). Such tubes should be put on the clamp in 3 or more layers.
You will also need stools of the same height. They shouldn't wobble. Several wooden planks should be prepared. Their cross section can be 30x30 or 40x40. Several wedges are cut from the same rail. You will also need a few strips of packing plywood. Drywall strips will also work.
Beginning of work
To install extensions for interior doors with your own hands, you need to follow the advice of experts. The opening prepared for installation must be properly marked. This procedure is called retraction. To do this, you need to use the Pythagorean formula. According to his theorem, right triangle, as everyone knows from school, the sides are related as follows: 3x4x5.
It should be noted half the width of the opening. At the bottom, this segment is equal to 3. For example, the width of the opening is 70 cm. Half of it will be 35 cm. The base length is 11.6 cm. You need to make marks with a cord, starting from the corners. Each of them should be 5.83 cm from each corner. From the intersection of these points to the middle of the width there should be a distance equal to 4 shares. This line will be perpendicular to the plane of the box.
From this line, all further horizontal measurements can be taken. The vertical plane of the opening can be checked with a plumb line. If you do not want to carry out such calculations, you should use the laser level. This is an accurate device that will allow you to perform all measurements correctly.
What not to do
Considering how to install extensions on interior doors, you should pay attention to some mistakes that beginners make.
Professional builders argue that it is impossible to use a carpenter's triangle during the measurement. The error will be large. Therefore, the gap between the door frame and the leaf can be large. It is better to use a calculation system or a laser level.
uneven walls
Installing extensions on interior doors requires accurate measurements. V standard apartments, and in private homes, it is not uncommon for the walls in the room to be sloped, uneven. If the indicator does not deviate by more than 5 mm over the entire height of the door, this situation does not need to be corrected.
However, it often happens that the deviation at different points of the opening is greater. In this case, when cutting additional boards, this feature will need to be taken into account. In this case, they are cut into a wedge.
Self-tapping installation
How to install extensions on interior doors? Most often, the owners of apartments and houses use self-tapping screws during this work. This reliable way fixation. If the slats are not telescopic (they do not have grooves), start the installation from the top slat. You need to measure its length and cut off the excess. Having attached the board to the wall, you need to check everything again. Then you can screw it to the wall.
After that, you can install the side boards. They are customized to size. For each side of the opening, the length of the side strips may vary. Next, holes for self-tapping screws are drilled in the slats. Attach a bar to the wall and screw it to the wall.
After that, you need to seal the joints. Hats deepen into the material. To do this, the holes are closed with plastic plugs. You can also just pick up a sealant to match the extensions. They cover all the holes in the boards.
telescopic dobor
How to properly install telescopic extensions on the interior door? This is a fairly simple procedure. Even if there are small errors, they can be masked. Telescopic slats allow you to do this. In this case, the installation procedure will take a minimum amount of time. The installation of telescopic extensions requires a minimum number of tools.
First, the wall surfaces are prepared accordingly. After that, the strips are applied to the surface, once again checking the correctness of the measurements. The installation of the telescopic dobor also begins with the top bar. After that, the length of the sidewalls is measured. The excess is cut off.
The groove is inserted into the lock to such a depth that the bar can completely cover the wall. With help rubber mallet you need to lightly tap on the joint surface. So the keys will be better fixed. If the groove and spike do not fit snugly against each other, they stagger, you need to use glue in your work. To do this, get liquid nails. After the extensions are installed, it will be possible to proceed with the installation of platbands.
Application of glue
Installation of extensions on interior doors can be done without self-tapping screws or tongue-and-groove joints. In this case, the strips are fixed with glue. This is a fast procedure. The outer side of the extensions remains intact. This is especially important when installing MDF planks. When drilling holes, the top decorative layer may crack. In this case, the appearance of the add-on will be spoiled.
To avoid such troubles, you need to clean the opening from debris, foam, etc. Next, special glue is applied to the back surface of the plank. The plank is applied to the base. Then you need to wait until the composition dries. This option is pretty simple. However, the base must be level. Otherwise, over time, in some places, the extension will peel off the surface.
Having considered how to install extensions on interior doors, you can perform all the steps yourself. The quality of the finished work will be high if the calculations are carried out very accurately. A large error can lead to serious design defects.
Most factory doors are designed for a standard wall thickness of 7-8 cm for city apartments. Therefore, the owners of suburban buildings, whose walls are most often much thicker than apartment interior partitions, we have to adapt to the realities proposed by the industry. The sections of the opening that are not blocked by the door frame are plastered, finished with drywall or plastic. However, it is much simpler, easier, faster to install an extension on the door, which is a kind of door frame expander.
Video - installation of telescopic extensions
Why install an add-on at all?
Extensions are two vertical posts and one upper horizontal bar designed to increase the “coverage area” of the box. Simply put, they expand the door frame. They are made from solid wood, MDF and fiberboard.
These slats can be purchased together with the door unit or purchased separately. The extensions do not differ in a super-complex design, and the home master can easily make them himself from lumber or slabs that replace wood.
Various installation methods
Assembled from three components into a single whole, the expander-addition "in full face" copies the letter P, it is attached:
- or directly to the door frame;
- or to the wall in the opening area;
- or on a mounting bar located between the vertical planes of the opening and the extensions.
Since no one will “put” a special mechanical load on the extensions, sometimes only liquid nails are used to fix in a specially made recess. But mostly they are mounted using galvanized self-tapping screws. If fastening is done from the front side, the fastener caps are hidden with mastics or matching plugs.
Reasonable benefits of extras
- Extremely high speed of construction and installation of a door block expanded with extensions.
- The absence of "wet" finishing processes, unfavorable for the neighborhood with wood.
- The maximum increase in the period between regular repairs.
And unconditional aesthetic priorities, providing the impression of the integrity of a presentable door structure.
Extensions for boxes with and without a groove
You can buy doors for arranging a country building:
- with boxes, in the outer side of which a grooved quarter is pre-selected for alignment with extensions;
- with a box beam without the above fixture.
With the first option, everything is relatively simple. For him, wooden or chipboard planks of centimeter thickness are suitable. The width of the slats-panels is measured with the base box installed in the opening. It is possible without it, but it is necessary to take into account that the addition only complements it. Defines the width distance from the edge of the opening to the end of the recess-quarter in the box. That is, the width of the extension is equal to the sum of the width missing to completely cover the opening and the transverse size of the recess. Most often it is 1 cm, but there may be other options.
Attention. All measurements must be taken at several points. Preferably at four. It is possible that the readings will differ. In case of deviations, the maximum is taken as the base size.
When fully assembled, the end line of the extensions should be flush with the opening line. Millimeter surpluses are squeezed with a planer, subsequently everything is closed by cashing.
The additional extension of the door structure with a groove only needs to be nailed to the base that is not installed in the opening on the reverse side with small galvanized nails in increments of 20-35 cm.
If the contractor has at his disposal a box beam without a notch made by the manufacturer, he can:
- choose a quarter on your own with a milling machine with a built-in ruler and a straight cutter, after which the box automatically switches to a clan of door elements with a device for installing an extension;
- attach extensions to the box beam through holes drilled through from the end with self-tapping screws;
Note. Diameter through holes for fastening the trim strips to the box is not the same along the entire length. First, use a drill with a diameter equal to the diameter of the screw head, then equal to the size of its barrel.
- install additional elements on bars screwed to the wall with self-tapping screws, place the first of them 20 cm from the floor surface and then after 55-60 cm;
- “plant” the extensions together with the box inside a kind of plasterboard or plywood base;
- connect the box beam without a quarter with the slats of the extensions by installing a rail passing from the outside of the structure along the entire alignment line;
- fasten the above-described rail or planks of plywood not in a continuous strip around the perimeter, but in separate segments.
Note. You need to nail both the beam and the dobor strips to the rail, its central axis should coincide with the connection line, but you can slightly shift it.
Depending on the massiveness of this addition to the door block, the owner himself chooses how to install extensions on the door. Any of these options is simple and quite feasible with your own hands.
The standard algorithm for installing add-ons
Usually, the upper plank, combined with the lintel, is superimposed on two vertical elements. To calculate its length, two thicknesses of additional racks are added to the length of the lintel. However, you can place it between them. Then the length of the ceiling extension will be equal to the width of the box, and the thickness of the upper bar must be added to the height of the left and right vertical elements.
So, the installation order:
- First, with scrupulous accuracy, we carry out measurements according to the scheme corresponding to the chosen installation method.
Note. For the left and right additions, vertical measurements are taken separately. It is recommended to measure the inner line of the future vertical strip along the box, the outer one in fact in the opening.
- The board purchased for the additional device is cut according to the measurements and the selected construction scheme.
- We attach all three additional parts to an installed or uninstalled, but fully assembled door frame.
- If add-ons were nailed or screwed to a box that was not installed in the opening, it must be installed together with add-ons.
- We place mounting wedges between the wall and the extended door frame and, by changing their position, we will align the structure in the opening.
- Before blowing the mounting gap with foam, we will install spacer wedges, both between the box beam and between the extensions.
- Foaming is performed in portions, at least in two steps we fill the space. We control the curing process, if necessary, make adjustments while the foam hardens. We complete the work by sealing the gap between wooden details and flooring and installation of platbands.
The listed ways of expanding the door unit are applicable to both interior and exterior doors. The difference is obtained only in the width of the additional slats. If an extension is being installed on the front door, most often the width of the standard extension boards is not enough. In such cases, several strips are connected to each other by means of slotted joints or specialized adapters.
If the hinge post is located near a blank wall, the box can be expanded in both directions. If there is no wall limiting the course of the canvas, and the door can “work” at 180º, the box is mounted flush with the outer plane of the opening, and the extensions are located on the side opposite to the opening / closing side. They should not interfere with the use of the door.
That's all the tricks with subtleties. What will be easier, more convenient, faster and more beautiful, you decide for yourself home master. It is important to know that any of the existing methods does not require special skills, but it is necessary to stock up on accuracy and attention.
When choosing interior doors, we try to make our choice based not only on practicality, their aesthetic side is also an obligatory fact. With the help of a properly selected door, you can add a special, unique style to the interior of the room.
Installation of extensions on interior doors is required when there is a difference between the width of the wall and the width of the door frame. Door dobors perform the following functions:
- closing irregularities;
- closing slopes;
- strengthening the main structure of the door;
- prevention of distortion of the door frame.
A completely logical question arises about how to install an extension on an interior door. And it is so possible to carry out the installation of dobors for interior doors with your own hands. Of course, it is possible, and the installation is carried out both on interior doors that have been installed for a long time, and on doors, the installation of which is only planned.
Existing types of add-ons
Depending on personal abilities and preferences, you can install dobors on interior doors with your own hands or give preference to those that are installed during the production process.
As a material for extensions, you can use the most different kinds boards.
When choosing a material, a lot depends on the type of room where the extensions for interior doors will actually be installed. If this room is present high level humidity, then the best option would be to finish the doorway with extensions and platbands,
Made from waterproof plywood. This material has the ability to maximize its stability and structure, despite the humidity.
Attention! If for a room with high humidity an ordinary board is selected, then there will be a risk of cracks and deformations.
Modern man strives for ideality and therefore many try to do everything with their own hands. But as practice shows, making dobors with your own hands is not entirely advisable, since dobors made in an industrial environment are much more profitable in terms of price. In the industrial process, the MDM is taken as the basis. She is undergoing preliminary decorative processing, and the size of finished extensions for interior doors is 80 - 550 mm.
The simplest and most standard installation procedure is to connect the extension to an existing recess. It is located inside the structure. In the event that the question arose of how to attach the extensions to an already installed interior door, you can solve this problem using extensions of the attached or underlay type.
Door installation process
In order to carry out the installation, you must have everything at hand. necessary tools, namely:
- manual milling machine for wood;
- circular saw manual;
- clamp with soft lining.
The clamp can be mounted on any flat surface, such as a stool. In this case, the disk should be located up. The result is a device that performs the function of a circular. Exactly circular machine will become the part that is simply indispensable in the process of installing extensions on interior doors.
Heat-shrinkable tubing is used as the material for the manufacture of sheathing on the clamp. It just needs to be made from several layers. Heat-shrinkable tubing requires heating in order for it to take shape, which requires each layer to be heated in turn and then cooled.
In addition to tools, some auxiliary elements are needed:
- stools of the same height in the amount of 3 pieces. For convenience, it is necessary to choose only very stable stools;
- slats made of wood with dimensions of 30 * 30mm.
- wedges in the amount of 10 pieces.
- drywall or plywood.
markup
On that doorway where the installation of the extensions will actually be carried out, it is necessary to first make a beating of the base plane. Special marks are made on the floor with a pencil. In order to make the beating as correct as possible, you should use the Pythagorean theorem. With the help of the above figure, let's try to figure out the correctness of its use:
- We measure the bottom width of the opening and take half of it. The half taken is equal to 3 base lengths, that is, equal to 3:1. If the bottom width is 60 cm, and we take only half, that is, 30 centimeters, respectively, one base length will be equal to 10 centimeters.
- At a distance of 51 centimeters from the existing corners, 2 serifs are made. As a result, from the intersection point (O) to the middle (B), the distance is 41 centimeters. The resulting straight line OB is equally perpendicular to the very plane of the doorway. It is from the received line that all measurements and calculations must be carried out.
Attention! If you can use the laser projector of the base surfaces, there is no need to do the above procedure.
What to do if the walls have a slope
It is quite possible that the walls have a slope. If the slope indicator is not more than 5 mm, then this can be corrected with a layer of plaster distributed under the casing. In the case when the indicator is greater, the use of wedges will be required.
Foam handling
After the procedure for installing extensions on the interior door is completed, you need to blow out all the cracks with foam. It is known that the foam has the property to expand when solidified and as a result, the jamb can lead. In order to avoid this it is necessary:
The procedure for installing extensions simultaneously with the box
Installation of the door frame along with the extensions is done in the following sequence:
Door with straight slopes
To facilitate the installation of extensions on interior doors, you must first prepare about 20 plywood wedges with a thickness of about 4 mm. After the preparation process, you can proceed with the installation of add-ons:
Type-setting extensions
If the wall cladding is carried out with MDF or other similar material, then the remaining pieces of material can be used as an extension for the door of the box. But if we consider this issue from a technological point of view, then, of course, this operation is more related to the wall cladding procedure and does not correspond much to the technology for installing extensions on the front or interior door.
What to do if the door is installed obliquely
In some cases, it is not rational to install additional material. This is exactly the case when the door jamb is skewed. This means that the degree of discrepancy of the upper bar has an indicator equal to more than 5%. Often, the distortion of the box design occurs when the manufacturing technology was violated during the production process. Failure to comply with the technology led to the appearance of defects.
Conclusion
Installation of extensions on door frame is nothing complicated. The only thing that is very important is to be as accurate and attentive as possible. It is very important to carry out all measurements as accurately as possible and check the evenness with a plumb line. When everything is done, the interior door will be operated long time and during the whole time there will be no problems.
How to take measurements correctly when installing extensions and platbands on the front door and interior door, we will find out in the next video
Installing doors is a responsible, but fairly easy process. How to install an interior door in an apartment with your own hands is described below.
Do-it-yourself installation of interior doors: step by step instructions
The interior door is formed by:
- box or frame - a supporting structural element;
- door leaf - the main part of the door, its "face";
- platbands - decorative elements, masking the joints of the frame with the wall.
Doors may also include:
- threshold,
- add-on elements.
The doorway, as a rule, has a width of 70, 80 or 90 cm. The door leaf is selected 10 cm narrower - its width can be 60, 70 or 80 cm.
Interior doors installed at the entrance to rooms such as kitchens, toilets and bathrooms often have a threshold. If the door is assembled without a threshold, a gap of 1-2 cm is left between the floor and the bottom of the canvas.
Additional elements - are used in cases where the thickness of the wall exceeds the thickness of the box. Their purpose is to improve the appearance of the structure.
In the general case, do-it-yourself installation of an interior door is done as follows:
- The frame is assembled and installed.
- The canvas is hung.
- Addition is installed.
- Platbands are mounted.
Guide to action
To install one interior door, you will need:
- mounting foam balloon;
- bar 40x40 for wedges and spacers;
- self-tapping screws;
- building level;
- tape measure, pencil;
- hacksaw or jigsaw;
- cutting saw.
Assembly and installation of the box
The assembly and installation of the frame is performed in the following sequence:
- Trimming racks - the height of the box is reduced in accordance with the size of the gap.
- Assembly - structural elements are connected into one whole (self-tapping screws are used).
- Preliminary fixation of the door frame - the upper and then the lower parts of the structure are fixed in the opening with wedges, a spacer is installed at the level of the lower wedges.
Installation of the canvas and final fixation in the opening
The sequence of work of this stage:
- Hanging the canvas - the canvas is connected to the frame from the side of the loops.
- Checking the operation of the door - the door is opened and closed several times, checking the smoothness of its course.
- Installation of additional wedges - wedges are installed at the level of the upper hinge and slightly below the level of the handle.
- The final fixation of the box - the gap between the frame and the opening is filled with mounting foam.
- Dismantling the wedges and trimming the protruding foam - after the foam has dried (one day after foaming), the wedges are removed or cut off and the excess foam is cut off.
Installing the addition of interior doors with your own hands is done as follows:
- The width of the area to be cut is measured.
- The trim strip is cut to the desired width.
- The dobor is inserted into the groove and foamed.
Important: if the width of the extension does not cover the entire width of the opening, two such elements and a connecting strip are used.
Installation of platbands
The order of work on the installation of platbands is as follows:
- The length of the elements is determined.
- The ends of the elements are cut at an angle of 45 degrees.
- The platbands are fixed in place with glue or nails.
As you can see, installing an interior door with your own hands is not so difficult. The main thing is to follow the instructions and be careful.
P.S. And for dessert, I suggest watching a video clip: Installing interior doors with your own hands
Dobory for interior doors can be installed independently. The materials required for this are inexpensive, and the right tools there are even a novice home master.
Dobory for interior doors: what they look like and what they are for
Dobors (additional boards) are wooden planks or MDF panels that cover door slopes. Such slopes are formed if the thickness of the wall is greater than the width of the door frame. As a result, the box does not cover the entire end of the wall and bare concrete or broken bricks are visible. Sometimes this area is plastered, wallpapered, covered with plastic, but it is easier, faster and more aesthetic to install extensions.
The design of the door block with the use of extensions
Unlike ordinary slopes, additional boards, as it were, continue the missing width of the box itself, forming a single structure with it. In order not to make a mistake with the tone, dobors are bought simultaneously with the door leaf and cashing.
Benefits of using
- Properly installed extensions look presentable and, depending on the overall style decision, bring an element of wealth and luxury or restraint and solidity to the interior.
- Attachments are fast and easy, which saves time, effort and money.
- During finishing works the door block does not come into contact with wet solutions, which prevents it from soaking and spoiling. Extends the life of the door.
Finished design looks nice and modern
Dobori can make your own or buy ready-made. The store will offer additional strips of standard sizes:
- length - 2.1 m;
- width - 7–25 cm;
- thickness - 6–30 mm.
To calculate the width of the additional plank, the depth of the groove in the box is added to the width of the slope, or the width of the box is subtracted from the thickness of the wall, taking into account the groove.
With particularly thick walls, the width of the extension can reach 40 cm or more, but such planks are made to order. The thickness of the trim strip must not exceed the width of the groove in the door frame..
Based design features, additional strips are divided into:
- ordinary;
- conventional with edging ends;
- telescopic.
The simplest extension is a straight strip of fibreboard (MDF) or laminate without a facing edge. Many masters believe that sticking a facing edge on the ends is a waste of time and money. After all, one end fits snugly against the door frame, and the second will be closed with a platband. But in this case, the installation must be carried out with special care, because even a deviation of a couple of millimeters will give out a novice master: a gray raw edge will be striking.
The simplest addition is a regular bar
If the end of the extension is previously closed with an edge tape matched tone-on-tone, minor flaws will be invisible. The edge itself costs a penny, and you can stick it in a few minutes using a regular iron. This method is also preferable because the edging of the ends prevents the MDF board from swelling under the influence of moisture. This is especially true for door blocks in kitchens and bathrooms.
A more perfect additional plank is distinguished by the presence of an edge at the ends
Most complex structure at the telescopic dobor. Its feature is the presence of special grooves that allow installation without the use of screws and nails. Moreover, it is almost impossible to miss: the dobor fits perfectly with the box and platbands. The width of the dobor is regulated by the depth of the groove. To make a telescopic extension yourself, you will need certain skills and a special tool. It's easier to buy ready-made slats.
Telescopic door extension has special recesses
Necessary tools and materials
When installing extensions, a minimum set of tools is used:
- level;
- roulette;
- pencil;
- saw or jigsaw;
- plane;
- hammer;
- sharp knife.
Necessary materials:
- polyurethane foam;
- fasteners (self-tapping screws, nails or "liquid nails");
- trim strips.
As a rule, extensions are bought together with the door leaf, but if the doors are not going to be changed, but they only plan to close the slopes, they are used to make extensions:
- wooden planks;
- pieces of MDF;
- long pieces of chipboard;
- plastic.
If applicable natural wood, to extend the service life, it is pre-treated with antiseptic impregnations.
Home-made extensions from ordinary MDF will differ from factory ones, since in industrial designs the inside between two thin fibreboards is filled with cellular material.
Chipboards lose to wood and MDF in terms of appearance and durability, but inside the room, chipboard extensions can be used.
Plastic as a material for the manufacture of extensions is rarely used. And if it is still used, then especially strong, metal-reinforced PVC panels are selected.
Dobors can be made from natural wood, chipboard, MDF panels or plastic
Installation of trim strips
Groove installation
If you plan to use extensions, then it is better to buy a door frame with a special groove. The presence of a groove not only speeds up the installation process, but also allows you to push / push the additional bar deep into the box by a few millimeters, which increases the accuracy of installation.
- It is assumed that by the time the extensions are installed, the door frame is already fixed in doorway. Therefore, first measure the distance from the door frame to the edge of the wall. All slopes are measured separately and each at least four points. As a rule, these indicators differ: even if the box is installed strictly vertically, the wall itself may turn out to be uneven.
It is convenient to take measurements with a construction square
- To the width of the slope add the depth of the groove in the door frame. The resulting value determines the width of the additional plank.
- With an electric jigsaw or saw, trim the extensions in length and width to the right sizes.
Additional strips are bought with a margin in width, and an exact fit is made during the installation process
- Dobors are installed in the grooves of the door frame.
The design of the door block using conventional extensions
- If telescopic extensions are used, then the door frame and trim must also be telescopic. The entire block is assembled as a constructor, inserting the protrusions of some elements into the recesses of others. For strength, additional strips and platbands are put on glue or "liquid nails". The structure assembled in this way looks like a single whole.
When mounting telescopic extensions, the tongue-to-groove method is used.
- The upper horizontal dobor lies on the side ones, forming the letter P.
The upper dobor lies on the side at a right angle
- To ensure the immobility of the extensions, they are temporarily attached to the walls and the box with masking tape.
- Eliminate the voids formed between the additional strip and the wall, filling the gaps with mounting foam. As a rule, spacers are installed between the extensions. If there are no spacers, the gap is foamed in several stages so that a too saturated layer of foam does not squeeze out the extensions inside the doorway.
The gap between the wall and the dobor is filled with foam
- Wait a few hours and after the foam has hardened, its excess is cut off with a knife.
The use of foam during installation allows you to do without nails and screws
Grooveless installation
If there is no special groove in the door frame, the extensions are fixed back to back. Such installation requires very accurate (up to a millimeter) measurements, careful fitting of additional strips and special care during installation.
- Measure the width of the slopes in the same way as when installing extensions in the groove.
- Trim the slats to the desired size. If extra millimeters remain after sawing, they are cut off with a planer.
- On the resulting sections are glued edging tape. To do this, the edge is ironed with a hot iron, as a result of which the glue on reverse side melts and the tape is firmly attached to the bar.
The edge is glued with an iron
- Thin nails up to half are driven into the ends of the extensions in increments of 20–25 cm. If glue is additionally used, three nails are enough for a vertical extension and one (in the middle) for a horizontal one.
- Nail heads are bitten off at an angle so that the end is sharp.
Nails are hammered into the end of the dobor and the hats are bitten off
- Install the extensions in place - first the side rails, then the top. The vertical dobor is pressed tightly at the bottom, slammed and finished off with a hammer so that the nail enters the door frame. Then nail the middle, then the top. Make sure that there are no gaps between the extensions and the box.
- The upper horizontal bar is placed on the vertical ones, the right angle is checked and nailed with a hammer.
After installing the extensions, the nails are not visible
- The gaps between the wall and the extension are foamed in the same way as when installing the extensions in the groove.
Platband installation
After the extensions are installed and the mounting foam has dried, the trim is fixed.
- Measure the height of the side rails. To do this, add the width of the upper casing to the height of the doorway.
The length of the vertical casing is calculated taking into account the width of the horizontal
- The top of the right casing is cut down at an angle of 45 degrees so that the edge of the plank that will adjoin the extension is shorter.
A miter box will help cut the casing at an angle of exactly 45 degrees
- Also at an angle of 45 degrees, but in a mirror image, the top of the left casing is sawn down.
- Saw off excess length from platbands.
- Vertical platbands are put in place and each is baited on two nails - at the bottom and in the middle.
- Apply the upper casing and make markings.
It is desirable to bite off the heads of the nails. So they will be almost invisible.
If self-tapping screws are used instead of nails, then a hole is first drilled into which the hat is drowned. Then they are screwed, and the caps are closed with special plastic plugs.
It is not difficult to install extensions for interior doors on your own, although the process cannot be called fast. But if everything is done correctly, the new door unit will become the main decoration of the room.
