What is better to make interior partitions photo Room dividers are a seemingly familiar construction. However, to ensure a comfortable stay, the partition must have a number of specific properties, including not only strength, but also lightness, sound insulation, and nailedness (the ability of a material to hold hammered nails by means of friction).

And if the strength of the materials is less and less clear, then the sound insulation of the partition is a difficult and ambiguous question. Well, let's try to figure it out. A bit of theory

All noise can be divided into air and structural. Air transmitted vibrations of air. Such noises are absorbed directly by the structure of the material: the more unclosed, sinuous, complex pores in it, the better sound absorption.

Structural noise is transmitted by direct contact and causes the structure to vibrate. In our case, the place of transmission of vibrations is the articulation with the neighboring structural elements (main walls, floors). And in some cases, the partition of the correctly selected material with a high sound insulation of its own “sounds”, conveying the noises of the “surroundings”. Moreover, the fluctuations will, as a rule, be significantly higher than, for example, at the main walls, to which it adjoins. After all, the thickness of the partition is less than that of capital structures, and the structure of the material is porous, which causes less rigidity than that of dense materials.

Therefore, it is important not only the material from which the partition will be made, but also the design, in particular, connections to the walls, floor and ceiling. How to evaluate sound insulation or airborne sound insulation index

The main standard value characterizing the airborne soundproofing of the structure is the airborne sound insulation index. Index ratio for each construction is different. According to SP 23-103-2003 for interior partitions, it is 41 - 43 dB (building categories AB). The partition enclosing the bathroom should have increased sound insulation, index 47 dB. However, today there is much more noise in residential premises created by household appliances than is customary in the calculations of standards. Therefore, according to the most modest estimates of experts, the index should be taken as a standard by an average of 8 dB more. Partition material

The most used options for partitions: brick, foam concrete blocks, plasterboard, plasterboard construction.

Each option has its pros and cons: Brick partitions

Of these materials, brick - the most traditional, familiar and time-tested. The sound insulation of a brick partition ½ brick thick (12 cm) is taken as a standard by current SNiPs. However, as we remember the noise background has changed since then, so a brick partition of ½ brick is usually not enough. In addition, the volumetric weight of a brick is about 1800 kg / m3, which is significantly more than that of foam concrete or plaster, not to mention a hollow-frame hyprock. Brick partition creates a significant load on the overlap.  What better to do interior photo partitions

To perform a flat brick tub, some skill is needed. The process is wet, will not do without dirt, spray solution, etc. One more minus - the need for exterior finish. As a rule, brick plaster to level the surface. The average thickness of the plaster is 1.5 ÷ 2.5 cm, which additionally weights the partition. Foam concrete partitions Foam concrete has a small bulk (of the order of 300 ÷ 1200 kg / m3 depending on the brand of foam concrete) and a structure with many closed pores. Foam concrete blocks are used not only for the construction of partitions, but also for the construction of buildings and structures (mostly low-rise ones) as a whole. This causes a large variation in the density of the material. Of course, the smaller the bulk weight of the material, the better the insulation from airborne noise, but in comparison with other materials, foam concrete loses: sound insulation of such a partition with a thickness of 100 mm reaches standard values ​​only when applying plaster with a layer of at least 10 mm on both sides (42 dB). Low density causes low protection against structural noise. Also a direct consequence of the low Bulk weight in foam concrete is the almost complete lack of ability to hold nails and screws. This low strength of the material will not be allowed to hang on the foam concrete bulkhead anything heavier than a painting.  what is better to make interior walls photo

Plus foam concrete blocks in comparison with the brick - a much larger size. The standard size of the foam block is 300,600 mm with a thickness of 200 mm for walls and 100 mm for partitions. It is easier to lay a partition out of foam blocks, although you can’t do without masonry skills here. The thickness of the standard unit 0.2 m, respectively, the partition "eat" more space. Like a brick, foam concrete blocks must be plastered before finishing. gypsum plasterboard partitions

Plasterboard slabs are made of alabaster of various kinds of emaciated. For the construction of partitions often use hollow tongue-and-groove slabs. Their advantages: lightness, strength, good sound insulation, the ability to securely hold nails, which is important in a residential area. What better to do interior partitions photo With a thickness of 100 mm, the volumetric weight of a plate with one row of cavities is 50-60 kg / m2; sound insulation - about 36 dB; with a thickness of 150 mm with two rows of cavities — 90 kg / m2; sound insulation - 39 dB. The design of the groove - comb causes a quick assembly on alabaster solution without special skills. Gypsum perfectly fills any shape, so the surface of the plates is clean, smooth and smooth. Accordingly, there is no need to align the septum. You can glue the wallpaper immediately, only a finishing layer of putty is needed for painting. Plasterboard Partitions

Plasterboard partition consists of a metal frame (single - or multi-row), two-layer sound-proof filling and sheathing gypsum boards (and possible one, but technically it is wrong). The advantages of this design - low weight, variation in size and configuration. The thickness of the plasterboard partitions varies from 12 cm to any desired width. Gypsum board, for example, allows you to perform a sliding door that disappears completely in the wall (two-layer structure with a gap, which is placed and a door leaf). Gypsum plasterboard also provides the ability to perform a curvilinear structure of almost any radius.  Plasterboard Partitions, GVL Partitions

The sound insulation of plasterboard partitions is different, as it depends entirely on the used filling. The most commonly used polystyrene foam, mineral wool, mats, etc. Penopolistiroll not a good sound insulation due to closed pore structure, but to work with such a filling can be without special protection. Mineral wool materials have higher sound insulation performance, but not all of them can be used in residential premises. When choosing a filling material, carefully read the certificates. Also, when working with mineral materials not to avoid a huge amount of small fragments of mines. fibers that penetrate the skin and settle on the mucous membranes of the eyes and throat. Therefore, in any case, do not neglect the means of individual protection (special suit, gloves and a respirator) and ensure good ventilation.

Knauf offers the “Schumanet-SK” insulation for filling the frame of plasterboard structures. With a metal frame thickness of 100 mm, insulation 55 dB.

After construction of plasterboard construction shpaklyuyut to hide seams and cap screws, as well as to prepare the surface for finishing. Insulation of structural noise

As you remember, the transfer of structural noise depends not only on the walls of the material, but on the correct implementation of the adjacency to the walls, floor and ceiling. In order to maximize the "quench" vibrations, not to let them be passed on to the partition structure, it is necessary to landfall was not rigid, "viscous". For this, the perimeter of the structure is framed with elastic gaskets (rubber, cork, elastomers). Also suitable polyurethane (mounting foam) or sealant based on rubber. As manufacturers offer ready-made solutions for plasterboard constructions vibration isolation pad "Vibrostek-M", for others - Sylomer.

Of course, each of the materials reviewed has its own advantages and disadvantages, and it will be wrong to weigh them on the same scale. The choice of one or another option depends not only on the material properties, but also on the specific problem solved by this partition.

Not by chance in our homes, perhaps, the most common are partition walls made of plasterboard. Light in the construction, divergent and with good sound insulation. However, in this case, the use of vibration pads is necessary; otherwise, all sound insulation efforts will be nullified.

Plaster gypsum partition walls, despite the low sound insulation, thanks to the ease and speed of construction is an excellent option to limit the space of the dressing room, pantry, etc., where sound insulation is not important. However, not all bad cam boards quench air noise. Modern manufacturers are constantly improving their products. Today, it has a layered structure of the plate - porous and dense inside out. Such material prevents the spread of sound much better. To clarify the characteristics of a particular material is better with the manufacturer.

Many foam concrete blocks also have a layered structure. But a large list of serious material flaws, which are mentioned above, still raises doubts about the reliability of this option.

The brick checked by time - a strong partition with quite good sound insulation which can be improved plaster. Despite the difficulties associated with the construction of brick structures (dirt, the need to attract specialists, subsequent plastering), this option is firmly in second place in popularity.
