What is an extension for a door?
Let’s try to briefly explain what an extension is for an interior door. These are special strips of various sizes and textures that are installed in openings if the width of the door frame is greater than the thickness of the wall. They serve not only to strengthen the door structure, but also to mask the defects present on the slopes, to give them aesthetics. Extras are an important element, therefore, in color, texture and style, they should be selected for the appearance of the door leaf. Trims can be installed in existing old interior doors or in new ones. Dobory can be mounted both on one or both sides of the opening, depending on the location of the box in it.
Additional panels are of the following types:
- telescopic;
- without edge;
- with an edge.
The material for the manufacture of these elements is wood, fine fraction (MDF), wood-fiber board ( MDF ), plastic. The horizontal and vertical planks are lined with decorative film or veneer of various types of wood.
Dimensions of doors for interior doors
Manufacturers produce additional elements of the following parameters: panel height is 2 m, thickness is 0.5-2 cm, the width of the strip can be from 10 to 14 cm. Custom doors for interior doors, the dimensions of which, as a rule, exceed standard parameters, are made for order. Door frames can have special grooves, which include the extension. Usually 10 mm thick panels are suitable for them. In this regard, when choosing an extension, the size of a quarter should be taken into account. There are no restrictions on the thickness of the additional board if the door frame is without grooves.
Installation Tools
For a quality installation of door extensions, you must have the following set of tools:
- circular saw;
- wood milling machine;
- clamp.
Using these tools, you can easily and quickly install extensions on interior doors, the price of one set of which will approximately amount to 580 rubles. After installation, you can be sure of the durability of this design.
Installation of additional panels
It is described above what an extension for an interior door is. Their standard sizes and the necessary tools for installation are also indicated. And now we’ll tell you how to set up an extension. Interior doors are best purchased with additional elements. Since, for aesthetic beauty, the entire wooden structure must be made in the same style.
Installation of an additional element can be carried out before mounting the door frame or after its installation. If you have chosen the first option, then the extension bars should be fixed on the back of the lout. In the second case, the panel is drilled through and fastened to the box with self-tapping screws.
There are times when the wall openings have unequal dimensions between the two sides of the slopes. Then the door frame is attached to a narrow part of the opening, and the one that is wider is closed by an extension. To do this, glued back and forth rails of 25-35 cm long on the back side of the vertical panels. Their cross-section should be such that, when mounted, there is a gap of 10 mm from them to the wall. Next, the panels are inserted into the groove of the door block, and the resulting small gap is blown out with foam.
Installing add-ons in such openings can be done in another way. A frame is made of the bars, which is attached to the slopes with self-tapping screws. The space is filled with foam and after it dries, vertical additional strips are glued to it.
In installation, the most convenient are telescopic elements having grooves, which makes it possible to install them in uneven openings. Such extensions for interior doors, the price of one set of which is 680 rubles, are mounted without the use of glue and screws. Their connection occurs due to grooves.
They begin to install the extensions with vertical panels, and then install horizontal elements. After completing their installation, platbands should be attached.
Clearance after installation
After installing the additional elements, the resulting gaps can be blown out with foam. In order for the foam, which tends to expand greatly, not to bend the door frame, some rules must be observed.
- Blow out the foam evenly.
- Do not remove spacers until it completely hardens.
- Hold the trim panels with spacers that should not exert pressure on them.
- Make sure that the foam does not go beyond the slope and does not crowd out the wells. Better to leave a small space, which can then be plastered.
After you find out what an extension is for an interior door and how to install it, it will be very easy to carry out installation work yourself.
