Partition is a structure that divides the interior space of the house into separate rooms and zones. Interior structures of this type can be built from different materials. But most often, bricks, foam and gas blocks, boards and timber or drywall are used for their construction.
Minimum thickness of room dividers
Different types of SNiP standards were developed primarily for the construction of multi-storey buildings. However, many owners of country plots who decide to build a residential building with their own hands usually also pay attention to such rules, although often their observance in this case is not mandatory.
This, of course, also applies to the assembly of interior partitions. For example, many home craftsmen are interested in what should be the minimum thickness of structures of this type. Of course, SNiP also regulates this parameter.
So, according to the rules, the thickness of interior partitions in residential buildings should be such that they providesoundproofing of divided rooms in 40-50 dB. That is, this parameter will depend primarily on what material is supposed to be used to build the structure.
Thickness of wooden partitions
Most often, low-rise country houses are divided into premises for various purposes using frame-panel structures. Such partitions are assembled from timber and boards. Only structures of this type on a frame assembled from a bar with a cross section of at least 100 x 100 mm can provide the level of sound insulation required by SNiP.
However, such thick material for assembling partitions in country houses is, of course, rarely used. A partition erected using such a beam will take up quite a lot of space in the building. In addition, the cost of a bar directly depends on its section.
In most cases, the owners of country houses assemble frame partitions using a beam of 70-80 mm. This indicator is the minimum thickness of an interior partition, including in a low-rise building. When using a beam of this section, it is also possible to provide the required level of sound insulation. However, in this case, when assembling the partition, you will have to additionally use mineral wool. This material is inserted into the partition space between the frame bars and provides the required sound insulation.
Brick partitions: SNiP
Such structures in country houses are built quite often. The thickness of interior partitions made of brick is usually 10 cm. This is explained by the design features of the material used for construction. The width of a standard brick is exactly 10 mm. Partitions are usually erected according to the “half-brick” method.
According to SNiP:
- the thickness of the masonry joints in the partition should not exceed 12 mm;
- when laying, dressing is mandatory;
- Building brick partitions is allowed only on a solid foundation.
Gypsum board constructions
When using this material, the thickness of the interior partition will also be fixed. Plasterboard partitions are assembled in most cases using a standard profile. In different situations, the thickness of such structures can be equal to:
- 75, 100 or 125 mm when using a regular profile and sheathing in one sheet;
- 100, 125, 150 mm for double sheathing;
- 155, 205, 255mm when using double profile and 1 sheet sheathing;
- more than 220 on a double profile with 2-sheet sheathing.
In small private houses without the use of soundproofing materials, the thickness of plasterboard interior partitions is usually 100-125 mm. When using mineral wool, they are made thinner - 75-100 mm.
Thickness of interior partitions made of aerated concrete blocks and foam blocks
In this case, the masonry is also carried out using the “half-brick” technique. That is, such partitions have a thickness equal to the length of the short side of the foamor gas block. There are several options for standard sizes of such building materials.
Foam blocks are usually used for laying internal interior partitions, the thickness of which is 10 cm, length 60 cm and height 30 cm. That is, in other words, in this case, the smallest version of this material is used. Accordingly, the thickness of the partition of such blocks will be 10 cm.
Aerated concrete piece material usually has the same dimensions. The advantage of foamed concrete, in comparison with brick, is a greater degree of sound insulation. That is, a 10 cm partition made of blocks will retain noise better than brick.
Advantages and disadvantages of frame-panel partitions
Designs of this type are very popular among summer residents and owners of country houses, primarily due to their low cost. Also, the advantages of partitions of this type include:
- ease of installation;
- environmentally friendly.
Very often for sheathing separating structures of this type, not an ordinary edged board, but a lining is used. In this case, the partition does not require additional finishing and is aesthetically very attractive.
Plus frame-panel structures, thus, have a mass. But such partitions also have certain disadvantages. The most important thing is the low degree of fire and moisture resistance. Furnace equipment near such structures, for example, putonly possible if certain rules are followed. It is not recommended to separate wet rooms with partitions of this type. Not only wood is afraid of water, but also mineral wool, which is most often used in such structures as a sound insulator.
Pros and cons of brick and block partitions
The minimum thickness of interior partitions according to SNiP, made of such materials, as we found out, is 10 cm. That is, partitions of this type usually occupy no more space in the house than wooden or plasterboard. At the same time, such structures are also distinguished by high strength and solidity. This can be considered their main advantage. Such partitions are assembled, of course, usually in brick or block buildings. And houses built from these materials can serve for decades.
The main disadvantages of separating structures of this type are the complexity of installation and high cost. In order to lay out a brick or block partition, you need to have at least minimal bricklayer skills. The materials used for such structures, in comparison with wood and plasterboard, are quite expensive.
Pros and cons of GCR structures
The thickness of drywall interior partitions, as we found out, can be different. The owner of the house has the opportunity to choose the best design option for this indicator. This, of course, is attributed to the unconditional advantages of partitions from the GKL.
As with frame-panel, such structures have two more main advantages - simplicityassembly and low cost. The installation of such partitions is often even cheaper than plank ones. However, unlike wood, GKL, unfortunately, cannot "breathe". In addition, in terms of environmental friendliness, such material is, of course, still inferior to boards.
Unlike frame-panel, plasterboard partitions can be assembled, including for separating wet rooms. This, of course, can also be attributed to the advantages of the material. The only thing, in this case, to assemble the partition, you have to use more expensive moisture-resistant green drywall.
Installation of frame-panel structures: features and requirements
Regardless of the thickness, interior partitions of this type usually do not differ in too much weight. Therefore, additional support for them is most often not equipped. The weight of such structures usually falls on the floor logs and the posts supporting them.
A feature of wood is the ability to change dimensions with fluctuations in humidity and temperature. Therefore, when assembling such structures, expansion clearance is required.
Partitions of this type are mounted approximately according to the following technology:
- the lower horizontal beam of the frame is rigidly attached to the floor according to the markup;
- vertical grooves are made in those two walls that the partition will subsequently connect;
- spikes are cut in the bar prepared for the extreme racks;
- racks are installed to the walls with the "castle" assembly and are additionally fixednails or screws;
- intermediate racks are installed using corners;
- boards are stuffed or lining is installed on one side of the beam;
- mineral wool slabs are inserted between the frame elements;
- the partition is hemmed with a board on the reverse side.
The temperature gap during the assembly of such structures is provided in most cases at the top - under the ceiling (about 1.5 cm).
Laying brick partitions
Such structures in the vast majority of cases are erected simultaneously with the construction of the building itself. The foundation under them is poured along with the base under the walls.
Regardless of how thick the house owners decide to make an interior partition made of bricks, the masonry mortar for such a construction is mixed from cement and sand in a ratio of 1/3. In order to give the mixture plasticity, masons usually add a little slaked lime to it as well. Before laying, the bricks are put dry and the row is leveled. Next, the wall is assembled using a mooring cord.
Sometimes it is necessary to erect brick partitions in an already built building. In this case, the structure can be laid out without first pouring the foundation. But it is allowed to do this only in those rooms where concrete was used to fill the floor. Start work in this case in this way:
- marking on the floor;
- make notches in the concrete and moisten it with plenty of water;
- put a strip of mortar 20 mm thick on the floor;
- lay out the first row of bricks with tapping with a hammer to obtain a bottom seam 10-12 mm thick;
- masonry using standard technology.
Block structures
Approximately according to the same technology as brick, foam and aerated concrete partitions are erected. But in this case, masonry reinforcement is additionally used for strength. The rods are inserted into the blocks in parallel every 4 rows. Gas and foam concrete is relatively fragile. Therefore, it is recommended to build such partitions only on a solid foundation.
Installation of plasterboard partitions
Standard thickness of interior partitions of this type is 100-150 mm. The assembly of GKL structures in most cases includes three stages:
- mounting the frame from the profile;
- installation of soundproofing material;
- plating GKL.
To assemble the frame of a plasterboard partition, two types of profiles are used - guide and riser. The connection of the elements of the supporting structure in this case is carried out using self-tapping screws. The frame elements are shortened when assembling the partition from the plasterboard, if necessary, using metal scissors. Lengthening is carried out using additional sections of the profile.
Rules for mounting frames under GKLthe following are followed:
- riser profiles are inserted into the ceiling guide by 2 cm;
- pre-vertical elements lead into the lower horizontal profile;
- racks adjacent to the wall are covered with damper tape.
Drywall when sheathing is cut using a construction knife. At the same time, the edges are chamfered by 1/3 at an angle of 45. The GKL is attached to the frame using screws, starting from the edge and moving towards the middle.
As with the use of wood, when assembling drywall partitions, temperature gaps are provided. In this case, they are left both below - near the floor, and above - near the ceiling. Screws on the surface of the sheets are placed in increments of 25 cm.
Communications inside partitions
Masking elements of various kinds of engineering systems used in country houses makes it possible to give premises for various purposes a more aesthetic appearance. Often, communications in such buildings are carried out precisely inside wooden or plasterboard partitions.
The answer to the question of how thick the interior partitions should be, in this case, will be quite large parameters. GCR structures, if necessary, laying communications inside them, for example, are mounted on a double profile. That is, the thickness of the structure in this case will have a minimum of 155 mm.
In the profile under the GKL, holes for pipes, for example, heating systems, are usually provided initially. In a beam atassembly of panel structures they have to be done separately. Communications are laid in partitions, usually before filing the second side of the plasterboard, board or clapboard.
