What is an extension for a door
Let's try to briefly explain what an extension for an interior door is. 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 on the slopes, giving them aesthetics. Extensions are an important element, therefore, in terms of color, texture and style, they should be selected to match the appearance of the door leaf. Planks can be installed in existing old interior doors or in new ones. Dobors can be attached both on one or both sides of the opening, depending on the location in itboxes.
Additional panels are of the following types:
- telescopic;
- no edge;
- with edging.
The material for the manufacture of these elements is wood, finely dispersed fraction (MDF), fiberboard (MDF), plastic. Cover horizontal and vertical planks with decorative film or veneer of various types of wood.
Dimensions of extensions for interior doors
Manufacturers produce additional elements of the following parameters: panel height is 2 m, thickness - 0.5-2 cm, lath width can be from 10 to 14 cm. standard parameters, made to order. Door frames may have special grooves, which include an extension. Usually 10 mm thick panels are suitable for them. In this regard, when choosing an addition, one should take into account the size of the quarter. There are no restrictions on the thickness of the additional board if the door frame is without grooves.
Tools for mounting extensions
For high-quality installation of door extensions, you must have the following set of tools:
- circular saw;
- milling machine for wood;
- clamp.
With the help of these tools, you can easily and quickly install extensions on interior doors, the price of one set of which will be approximately 580 rubles. After installation, you can be sure of the durability of this design.
Installation of additional panels
The above describes what an extension for an interior door is. Their standard dimensions and the tools required for installation are also indicated. And now we will tell you how to install the extension. Interior doors are best purchased together with additional elements. Since for aesthetic beauty, the entire wooden structure must be made in the same style.
Installation of the additional element can be carried out before mounting the door frame or after its installation. If you chose the first option, then the additional strips should be fixed on the reverse side of the loot. In the second case, the panel is drilled through and fastened to the box with self-tapping screws.
There are times when wall openings are not the same size between the two sides of the slopes. Then the door frame is attached to the narrow part of the opening, and the one that is wider is closed with an extension. To do this, slats 25-35 cm long are glued end-to-end on the back side of the vertical panels. Their cross section should be such that when the extensions are 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 with foam.
You can install extensions in such openings in another way. A frame is made from 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 onto it.
In installation, telescopic elements with grooves are most convenient, which makes it possible to install them in uneven openings. Such extensions for interior doors, the price of one setwhich are 680 rubles, are mounted without the use of glue and self-tapping screws. Their connection is due to the grooves.
Mount dobors start with vertical panels, and then install horizontal elements. After completing their installation, platbands should be attached.
Eliminating gaps after mounting extensions
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, you must follow some rules.
- Foam should be blown evenly.
- Do not remove spacers until they are completely solidified.
- Support the extension panels with spacers that should not put pressure on them.
- Make sure that the foam does not go beyond the slope and does not displace the extensions. It is better to leave a small space, which can then be plastered.
Once you have learned what an extension for an interior door is and how to install it, it will not be difficult to do the installation work yourself.
