If the back wall - does not mean unimportant!
Cabinets can be made as a separate enclosure and built-in.
Built-in mounted directly to the wall of the room at the place of their location. The advantage of individual models is the ability to disassemble, move and put them in any place. Hull models always have the back wall of the cabinet. It isolates the interior of the cabinet, making it aesthetic, especially if the wall behind it is uneven, without finishing. The back wall of the cabinet rigidly fastens the entire structure, keeps it strictly upright.
The sliding wardrobe is divided into sections, drawers, shelves and filled with things very unevenly. Under the influence of the load wardrobe compartment can be deformed. To prevent this, in addition to the rear wall, special stiffening ribs can be provided inside.

What is the back wall of the cabinet made of?
The back wall of the cabinet is made of wood fiber boards (DVP), laminated chipboard (LDSP).
Fiberboard consists of wood fibers, synthetic resins, fillers, water.
Differs:
- for general and special purposes;
- hardness - superhard, hard, semi-hard, soft;
- by thickness.
Plates can be smooth on one or two sides, varnished, covered with laminate film, artificial veneer. They also differ in the degree of response to moisture, fire resistance, exposure to sunlight. The most commonly used are solid species: small dispersion fraction (MDF) or hardboard and harder, modern material HDF from coniferous woods.
Chipboard is a mixture of sawdust and resin, which under the influence of high temperature and pressure turns into a homogeneous, durable material.
Differs:
- grades, which are determined by the appearance of the product;
- by the number of layers;
- according to the degree of surface roughness: unpolished,
ground, laminated;
- by density;
- for some other indicators.

As we can see from the table, what the back wall of the furniture is made of affects the appearance, ease of assembly, and durability. The back wall of the cabinet, the material of which is laminated chipboard, is better in all respects, but also costs more than five times. Naturally, its use significantly weights the product.
In the case of high-sized models and a large load, for example, in the form of books, the question: from which the back wall of the cabinet should be made, does not arise. For safety and reliability, this should be done from chipboard.
In other models, the material of what the back wall of the cabinet is made of can be a fiberboard, which is not only thick and dense. Fiberboard has a good margin of safety. You can also note the duration of operation (up to 30 years) while maintaining the original parameters, the environmental safety of the plates.
How to strengthen the back wall of the cabinet?
Fixing the back wall of the cabinet is not an idle question. Some people suggest nailing the back walls of the cabinets.
Yes, this method allows you to do this quickly, but this mounting of the rear walls of cabinets reduces the rigidity of the structure and its strength. In this case, the material of the body and the wall is destroyed, difficulties are created later on when disassembling such a product. Not recommended and the use of construction stapler. It is best to use screws with washer.
If chipboard is used, then the holes are drilled first, so as not to split the plate, and then the screws are screwed. Improves the rigidity of the whole structure and the fastening of the sheets in the grooves selected with a milling cutter in the end posts, lid and bottom of the product. At the same time, it is important that the sizes of the sheet being fixed coincide with the dimensions of the place to be closed.
Fastening is carried out around the perimeter:
- to partitions and end walls;
- overlap from above;
- to the base of the structure;
- to capitally fixed shelves.
How to fix the wall at the junction?
One sheet may not be enough to cover the entire back surface. To do this, use a few sheets. In this case, the following sheet joining options are possible:
- if the joint lies on the end of the partition:
- both sheets are pressed against the partition using self-tapping screws and washers;
- sheets overlap;
- if the joint does not fall on the end of the partition:
- both sheets are connected using a mortise bar into which they are inserted;
- sheets are glued together.
To overcome these problems, you can design a compartment of sections, for each of which would be enough one sheet. Sections are assembled separately, then they are connected to each other at the place where the product is located further and form a single structure.
