To give the doors a final look, special trims are installed. Let's consider how to choose the sizes of extensions for interior doors and correctly install all the elements.
What is an extension for a door?
Extras are specialized strips that differ in parameters and textures. They are attached to the openings and close the slopes.
They are put in several situations:
- If the width of the box does not match the wall thickness (masking irregularities, sealing slopes);
- To strengthen the mounted web, eliminate distortions.
Extras for interior doors are an important detail, so they must be selected according to the style, shade and structure of the panel (looks like a frame). They are bought in the kit to prevent mistakes. Panels can be mounted in already installed or new doors on one or two sides of the opening (according to the location of the box).
Mounted extras look prestigious and, based on the general style, make the interior solid, luxurious or restrained. They are fixed quickly and easily, which saves time and money. When decorating, the door unit does not come into contact with wet compositions, does not soak and does not deteriorate. This extends the operation of the structure. In comparison with standard slopes, an additional board becomes a continuation of the missing width of the box.
What are the types of add-ons
Everyone chooses the technique of mounting strips, this can be done on their own or contact professionals. For the manufacture of elements, a flat, grooved or edged board is suitable.
If the walls are thicker or the installation is carried out in a humid room, then waterproof plywood is considered suitable, which resists various deformations (delamination, cracks). Dobras made in production look more aesthetically pleasing and economical. The main material is MDF panel, covered with a decorative layer. In addition to the fact that the finished boards have different dimensions (length 80-550 mm), they differ in the type of material and cost.
Based on the type of design, the following options are distinguished:
- telescopic;
- standard without edge;
- standard with an edge;
- combined.
Fig. 2. Types of add-ons
Standard elements are simple laminate or MDF battens, coated with veneer, with or without other coating. Based on the quality of the end face, they may have an edge. Some experts believe that it is not necessary to glue the facing edge to the edges, since one end is in close contact with the door frame, and the other is closed with a platband. In such a situation, it will be necessary to carry out careful installation, since even with a slight deviation, the raw edge will become noticeable.
If you close the end of the bar in advance with an edge tape of the corresponding shade, then minor flaws will not be noticeable. The cost of the edge is low, and you can glue it quickly with a simple iron. Edge trimming will be preferred since swelling of the material from moisture is prevented.
A more complex design has a telescopic (typesetting) element, which can be attached to another thanks to a special comb and a groove on the edge. With it, you can make the lining of the opening of any width. The principle of its manufacture is identical to lining. The telescopic extension is distinguished by the shade, thickness and type of material. The bar is placed in a groove where it can be adjusted, wedging deeper or plunging to a shallow depth. Installation does not require the use of fasteners. Typically, telescopic products correspond to the material of the panel, so they are made of plastic or wood.
The combined plank has a angular shape, since it simultaneously plays the role of clypeus and extension. For the production of planks, MDF, fiberboard, waterproof plywood are used, which are veneered or covered with a decorative film.
Do I need an extension for the door frame
In any room, doors and ducts differ in parameters and characteristics. For example, in a bathroom their sizes are already interior, entrance doors are more spacious. Therefore, there are standards and size ranges.
When the width of the box is measured, it is necessary to determine the performance of the opening and the panel, since all the characteristics are interconnected.

Regardless of the convenience and aesthetics of extras, they do not always need to be set. Their installation is carried out only in a situation where the width of the box is less than the wall opening for the frame.
How to choose the right type and size
Planks can be made with your own hands or bought ready-made. On the construction market there are additional products with standard parameters (0.7-2.5 cm wide, 0.6-3 cm thick and 2.1 m long).
To determine the required panel width, the slope size must be added to the groove depth of the box. With very thick walls, the bar can be 40 cm thick, but it will need to be ordered individually (its parameters should not exceed the dimensions of the groove in the box).
To make planks yourself, you should take wood, MDF, particleboard or plastic.
When using natural wood, it is coated with antiseptic compounds to protect against rot and prolong service. Home-made MDF products will differ from purchased ones, since in the latter, the cavity between the plates is filled with cellular material. Chipboards are worse than MDF or wood panels in terms of operation and aesthetics, but they can be used indoors.
Planks are less often made of plastic, but if this happens, then PVC panels reinforced with metal are used.
Installation of additional panels
The following tools are used to fasten the panels to the opening: level, planer, tape measure, jigsaw, hammer and sharp knife. Of the building materials, foam, fasteners and trims are required. To correctly deliver the products, you must follow the instructions.
Installation of any types of extensions on interior doors can be carried out in several ways:
- Grooved mounting. If you plan to use the strips, it is desirable that the box has a special groove. This will speed up the installation process and allow you to slightly extend (or push) the bar inward, increasing accuracy.
The box should be fixed in the opening, so before you put it, the distance from it to the edge of the wall is measured. The size of each slope is done separately at least at 4 points using a construction square. Typically, these indicators vary. The width of the slope is the depth of the groove in the box, resulting in the parameters of the bar. You can trim the extension with a saw or a jigsaw to the optimal size.
When using telescopic products, platbands and a box of the same type are selected. The assembly of the block is carried out according to the type of designer, by inserting the protrusions into the recesses of the parts. Glue provides additional durability to panels and platbands.
- Mounting without groove. If there is no groove in the box, then the elements are attached tightly. Such an installation requires accurate measurements, a detailed fit of the elements and accuracy.
The size of the slopes is determined similarly to the first installation method, parts are trimmed, an edge is glued to the slices. Nails are hammered into the end parts in increments of 20-25 cm and their hats are bitten off with pliers. Then they put the side strips, after which the upper one is at a right angle and nailed with a hammer.
- Fastening with screws. The width of the extension is determined, which is screwed to the wall, the side parts are sized. Holes for screws are made and screwed to the wall.After sealing the joints, the platband is attached, furniture plugs are installed to mask the screws.
Clearance after installation
The immobility of the extensions can be ensured by fixing them with masking tape to the box and walls. Spacers are placed between the two elements, and in their absence, the gap foams. You should take the bottle and introduce foam in small portions (so that the structure does not move). After it dries, the excess is cut with a knife on the level of the wall.
Door extensions allow you to aesthetically design the opening. With minimal handling skills with glue, nails, saw and foam, such work can be done independently.
