Hello, hello, our brave plasterboarders. Today you will find a cool tutorial on the topic of drywall partitions. Speaking specifically, we will disassemble a single-layer partition on a single frame - C 111 according to the Knauf classification, because. such partitions are most widespread. Let's deal with general principles their installation, how to form a doorway, an external corner and pairing several partitions with each other. As an example, we will take a corner partition with a doorway, such as pantries and dressing rooms (essentially moth nurseries) are usually enclosed to store pickles / jams and all sorts of junk that is long overdue to be disposed of.

Please note that work with drywall can only be carried out after the plaster and screed in the apartment have completely dried.

To begin with, let's get acquainted with the special profiles that serve to form the frame of the partitions. These profiles are called rack-mount. To be more precise, there are exactly rack-mounted PSs (CW), and there are also special wide guides PN (UW) for them. Dimensions of guide profiles: 40×50, 75, 100 mm. In our example, profiles with a width of 100 mm will be used. The letters C and U in their bourgeois name indicate the shape of their section. As you can see in the picture, the guide shelves are straight, like the horns of the letter U, and the rack - with roundings, like the C. By the way, the shelves are called side faces profiles, and the walls - back. The second letter of the overseas name means that the profiles are rack-mounted, i.e. wall from the German "Wand".

Rack and guide profiles Knauf

They are in paired version.

Once again, we repeat that you can only use a profile with a metal thickness of 0.55-0.6 mm, for example, Knauf. They are good not only because of the rigidity, but also because their design allows you to insert them into each other, thereby achieving their elongation and reinforcement on the sides of the doorway. Profiles from other manufacturers may not be able to do this. In the walls of the PN there are already ready-made holes with a diameter of 8 mm for dowels.

Dimensions of rack profiles: 50×50, 75, 100 mm. For single-layer partitions, the 50th posts are rather weak, so we advise you all to take the 75th or 100th. In the walls of rack Knauf profiles there are 3 pairs of closely spaced holes with a diameter of 33 mm for laying wires.

On the next slide on the left - a self-tapping screw with a press washer, it serves to fasten the profiles together. There is an option with a drill and without. They are designated, respectively, LB and LN. On the slide - option LN. In our case, they are needed only if there is no cutter. On the right is a drywall screw. More precisely, it is all the same for metal, but it already serves to fasten sheets of the Civil Code to the profiles. Therefore, most often it is called that - a drywall screw. Has a secret, so-called. carob, head. Designated - TN. There is also a TB, with a drill at the end, but you can do without it, 0.6 mm steel TNs will easily be taken.

Self-tapping screws for mounting structures made of plasterboard

Do-it-yourself instructions for installing a plasterboard partition.

Step 1. Markup

For example, let our partition be a continuation of an existing wall. It is highly desirable to pre-align the beacons. We draw a line-the continuation of the wall on the ceiling, we make a right angle with a simple square. This line is the inner border of our future partition, taking into account its final dimensions. But we first need to mount the frame, and for it the dimensions are different. It is not necessary to draw your own lines for the frame, you can make everything easier. How? Find out very soon...

Marking lines on the ceiling

For now, we transfer the lines from the ceiling to the floor using a plumb line and a cord breaker, or a laser level.

Transfer markings to the floor

And now in front of you is the very simplified way of marking the PN.

Mark holes for fasteners

The bottom line is that pieces of drywall are sewn onto the guide profiles cut to size, which are already set along the lines. With this approach, the risk of error will be minimal. We mean that later, when the Civil Code sheets are sewn on, the rule will not “jump” at the wall/partition boundary. Pieces of GKL should be sewn flush with the walls of the PN. We expose the profile with these pieces along the line and put marks with a pencil or marker where we will have holes for attaching the PN to the base.

From a different angle

Step 2. Fixing the PN

Then, according to our marks, holes are drilled in the base, and a sealing tape is necessarily glued to the profiles. Its absence is capable of completely ruining the entire soundproofing of the future partition. With it, the adjunction to the base will be very tight, which also affects the crack resistance of the structure. The fastening itself is carried out with dowel-nails using an ordinary hammer. Fast and strong.

Attaching the profile to the dowel-nails

Guides on the floor

Near the opening

On the ceiling

We do not unscrew the pieces of GKL from the profiles until we fix the PN at all the necessary points. Often there are situations when the holes available in the PN are not enough. In these cases, they should be drilled independently, and you can do it in one go - through the profile to the base. The main thing is to carefully monitor that the boundaries of the GKL pieces clearly coincide with the marking lines. After fixing the guides on the sides of the doorway, I advise you to check them with the rule and make sure that they lie exactly on the same line.

You need to make at least three attachment points per profile. Even if it is 30 cm long. Usually, the fastening pitch is made in the region of 50 cm. If the floor is uneven, the pitch is reduced. Sometimes you even have to divide the PN into several segments. We do the same on the ceiling. Then we unscrew the pieces of GKL, but do not throw them away, they will still be useful to us ...

Step 3. Mounting wall substations

Fastening racks to walls

We cut the rack profiles in height, insert them into the guides close to the walls and drill holes in the walls right through them. Try to maintain a step of about 50 cm, no more. We hammer the dowel-nails into these holes again. Do not forget to glue the walls of the profiles with sealing tape! And control them by the rule, they should not be bent. By the way, the height of the substation must be less than the height of the ceilings in the room, at least 1 centimeter. They should not support the ceiling.

The length of the racks is 1 cm less than the height of the ceiling

As you can see, there is some distance between the rack profile and the floor.

Step 4 Installing the frame posts

The rack profiles of the frame are installed in increments of 60 cm. If tiles are laid on the partition, then in increments of 40 cm. The profiles of the doorway are extraordinary, and they do not affect the pitch of the remaining substations. The slide shows the profiles set at 60 and 80 cm from the wall. Near PS just forms a doorway.

Partition frame posts

To reliably form an opening, the side PSs are made double, that is, one PS is inserted into the other. Of course, this is done in such a way that the holes in the walls of these profiles coincide in height. Inserting the PS into each other is not an easy task, sometimes you have to walk on them with your feet so that they snap into place along the entire length. It turns out that on the slide you see 3 profiles, but in fact there are 4 of them.

PS are set in one direction - with the wall to the corner from which the plasterboard sheathing will begin. Maximum weight door leaf, which can withstand a pair of PS-100 - 40 kg. Rack profiles are installed strictly vertically. Their length should be 1 cm less than the height of the ceilings. And the holes in all profiles must be at the same height. Profiles can be fixed to the rails using a cutter or self-tapping screws with a press washer (temporarily). Before patching the GKL, all self-tapping screws must be unscrewed.

Racks in place

Yes, PS are installed in one direction, because the fastening of sheets should begin from that part of the profile shelf, which is closer to its wall. If you do the opposite, the screws will jam the profile shelf, and it may bend. On the slide you see an almost finished partition frame. Let's take a look at how the outside corner is formed correctly...

Forming the outer corner

Frame from another angle

One of the rack profiles is turned with the wall outward, and the second one stands with a shelf towards us. A distance equal to the thickness of the GKL was left between them, we laid it at the stage of fixing the PN. Thus, a sheet of Civil Code with inside partitions will wind up, as it were, into its depths. At the end of the article, the outer corner of the fully finished partition will be shown in section.

Step 5 Jumper

Jumper from PN

It remains for us to make a jumper for the doorway. It is made from a guide profile by making an oblique incision of its shelves and bending a part of its length by 5-7 cm. The slide clearly shows how it will look. That is, you will need to cut a piece of PN 10-14 cm longer than the width of the opening. Cut and fold it symmetrically. On each side, the jumper is attached to the side posts with 2-3 LN screws.

Installing a jumper in the frame

Now our frame is completely finished. It is possible to pass electric cables through the frame. But you should not bring them inside the profiles, as they can be pierced with TN screws when sheathing the GKL.

Step 6. GKL sheathing

Sheathing the frame with drywall

BEFORE jumpers

There are several rules here.

• We have already mentioned the first one - you cannot join sheets on the side profiles of the opening.
• Secondly, cruciform joints of the “+” type are unacceptable, only of the “t” type.
• Thirdly, the joints of the sheets on the inside and outside should be horizontally shifted by a profile step, and vertically by at least 40 cm. On the slide, you can see the very pieces of drywall that we used for marking. Now they serve us as props. After all, the sheets of the Civil Code cannot be placed directly on the floor, they must be raised above it by about 1 cm.
• And they should not reach the ceiling either, about half a centimeter. This is the fourth rule.

To fix the drywall to the double posts of the opening, you can use small metal drills. Otherwise, very often the screws just jam inner part profile. First, drill holes through the gypsum board, then screw the screws into them. Of course, sheets can only be joined horizontally on profiles, which means that we must make jumpers from PS at the joints. See how they look on the next slide.

PS jumpers

These are segments of conventional rack profiles. To fix them, again, you need to start from the side of the shelf, which is closer to the wall. In the matter of mounting the jumpers, it is desirable to have an assistant who will hold the sections of the profiles while you turn the screws in them. As soon as all the jumpers are placed, it is possible to lay soundproofing plates (mineral wool) between the profiles. We like ISOVER the most. When laying, we try not to leave unfilled areas. It should be cut off with a margin of about 5 cm so that it abuts against the profiles and thus keeps in the frame. When working with mineral wool, be sure to use goggles, a respirator and gloves!

Sheathing process

Sheathing process 2

Finished skin

The step of the screws is about 20-25 cm. On the jumpers, it is advisable to twist them more often, after 10-15 cm. Make sure that the heads of the screws are deepened into the sheet, but do not pierce the cardboard. If the cardboard is pierced, the screw should be twisted. More importantly, the screws must enter strictly at right angles. They must be at least 15 mm from the edge of the end edge of the sheet and at least 10 mm from the longitudinal edge. By the way, GKL can only be mounted in a vertical position! If a stretch ceiling is planned in the room, it is advisable to mount PS mortgages under it in the partition, into which we recommend additionally inserting a beam of the appropriate size.

I also recommend screwing self-tapping screws into the jumpers on both sides of the partition, and not just from the side of the joint. It is advisable to guess the location of the sheets on outer corner so that they would lie on it with a factory edge. Then, when we install a protective corner on it, it will deepen and the plane will not deteriorate. Of course, all progressive mankind has long been using a special corner-proof paper tape, Sheetrock, for example. But we know that it’s hard to find one in our country, so our Stone Age has dragged on, and we still use outdated metal corners. So, the partition is assembled.

The thickness of drywall partitions: selection and calculation

Greetings, comrades! Today we have to find out what the thickness of a plasterboard partition can be, depending on the requirements for it, what factors affect this parameter, and what are the minimum and maximum thicknesses of a plasterboard wall. Let's get started.

Components

What is our design?

Image	Description
	frame: rack and guide profiles. Racks provide a rigid structure of the wall, guides - fastening racks to the walls. The size of the rack profiles varies from 50 to 100 mm, the guides have the same section at a fixed height of 40 mm.
	sheathing: GKL is attached on both sides of the profile. The partition is sheathed in one or two layers. In addition, the drywall itself has a different transverse size: wall sheet - 12.5, ceiling - 9.5 mm.

In addition to the ceiling and wall, there is an even thinner arched drywall (6 mm), but it is not used for wall cladding.

I deliberately do not consider structures on a wooden frame. He has too many serious flaws against the background of a galvanized profile:

• Non-ideal geometry;
• Tendency to deform with fluctuations in humidity;
• fragility: the tree is affected by fungus and insects.

Factors

What influences the choice of frame and skin dimensions?

1. Stability Requirements partitions in relation to horizontal loads. This parameter is especially important in rooms with high traffic (corridors, hallways, kitchens) and in cases where drywall wall encloses a room stretch ceiling from PVC film;

Reference: when tensioned, the vinyl sheet creates a horizontal load of 70 kgf per linear meter on the baguette.

1. wall strength requirements with respect to impact loads. A typical example of a room with high requirements is a nursery. Thin single-layer drywall can break when a native starts hitting it wooden typewriter or a pirate saber;

1. Wishes for soundproofing possibilities walls. The thicker it is, the greater the layer of noise-absorbing material laid between the racks of the frame can be;
2. The need for hidden laying of engineering systems. In the wall can be mounted electrical wiring and the local network, plumbing and sewerage, ventilation ducts and air conditioning lines.

Calculation examples

Let's, as an example, do a few partition calculations for various requirements for it with our own hands.

Space saving

If the main priority is saving the usable space of the room, the minimum wall thickness will be equal to the sum of:

• The transverse size of the rack profile (5 centimeters);
• The total thickness of two sheets of plasterboard (9.5 or 12.5 mm).

Total - 50 + 9.5 + 9.5 = 69 or 50 + 12.5 + 12.5 = 75 mm.

The thickness of drywall for partitions of 9.5 millimeters is permissible only if it does not experience mechanical stress in principle. A sheet of ceiling plasterboard is easily and naturally broken through by an accidental blow of an elbow or knee.

Thin but strong

If you want to combine space savings with maximum wall strength, its optimal design- reinforced frame made of a thin (50 mm) profile and double skin (one-sided or two-sided).

How can the frame be strengthened?

• Wooden mortgages from a bar 50x50, nested in racks;
• Pairwise connection of rack profiles with a standard step between them of 60 cm;
• Reducing the step between the racks up to 40 cm.

The final thickness with two-sided two-layer sheathing will be 50 + 12.5x4 = 100 mm.

Noise isolation, hidden laying of communications

If you plan to run a plumbing, 50 or 90 mm sewer inside the frame, or if the wall must provide maximum sound insulation, it is wise to opt for a frame maximum thickness- from a 100 mm profile.

In the absence of special strength requirements, the wall sheathing is made single-layer. The final thickness is 100 + 12.5x2 = 125 mm.

Extreme noise isolation

To absorb the maximum noise, it is necessary not only to fill the cavities of the frame with noise-absorbing material, but also to acoustically decouple the skin on both sides of the partition. How to do it?

Here is the instruction:

• Build two parallel frames from a 50 mm profile with a minimum (5-10 mm) gap between them;

For better sound insulation a damper tape is laid under the guides. It eliminates the transmission of acoustic vibrations from the profile to walls and ceilings.

• Fill the frame with slabs of glued mineral wool. Its standard size (600x100 mm) allows you to do without additional fastening: plates are installed spaced between racks;

• Sheathe the resulting structure with drywall on both sides. It is better to resort to a two-layer sheathing. The price of several additional GKL sheets will pay off with the greater strength of the wall and its lower permeability for high-frequency sound.

The maximum thickness of such a wall will be equal to 50 + 50 (two frames of thin racks and guides) + 5 (gap between them) + 12.5x4 (two-layer sheathing with wall plasterboard on each side) = 155 millimeters.

Conclusion

I hope that this material will help the reader to choose the best solution for his purposes. Learn more about installation drywall partitions The video in this article will help you. I look forward to your additions to it. Good luck, comrades!

Drywall constructions are the most popular solution for creating partitions and full-fledged walls with an integrated door in private houses and apartments. Optimal specifications, low cost and ease of installation made drywall combined with metal profile most practical solution to demarcate space.

Determining the thickness of a plasterboard partition is an important stage in the design of a structure, at which the builder must decide on the purpose of erecting the structure and its purpose. So, when creating decorative partitions, you do not need to take into account complex decisions, laying in it a sound-proof layer, cables. But, if the GKL is used to build a full-fledged wall, which must be designed for certain mechanical loads, do the most simple solution will not work.

For the construction of partitions from gypsum boards, steel or wooden profile from a bar. Sheets cover 1 or more sides of the structure, between which soundproofing material or additional plasterboard is placed. The thickness of the partition depends on factors such as: the type of sheets used, the profile. At the same time, there are more than 5 design options, each of which is designed for different tasks:

1. C111. The simplest profile, the weight of which does not exceed 28 kg per cubic meter finished construction. The structure includes 2 litas of moisture-resistant gypsum board, located inside the mineral plate, which performs the function of a noise absorber. The minimum width depends on the profile, which can be 50 or 100, as well as drywall sheets, the standard is 12.5 mm per side.
2. C112. Improved profile, the total weight of the structure reaches 53 kg at a height of 4 to 9 m. Sheathing is carried out in two layers on 2 sides, and inside there is mineral wool. The thickness of the drywall partition depends on the profile and sheets - most often 100 and 12.5 sheets are used in 2 layers. Structures of this type have good soundproofing properties.
3. C113. The weight of the partition per meter is 78 kg, and inside, waterproof drywall is used in 3 layers, with mineral wool between the sides. Perfect solution for places where you need to protect yourself from noise and keep warm.
4. C115.1. It is built from a double frame and 2 layers of plasterboard, the weight of the structure reaches 57 kg. Well protects from a sound, possesses the increased durability. If fire-resistant panels are used, the fire safety class increases. The minimum section depends on the profile, either 50 or 100. Plus 25 mm of two sheets of drywall on both sides.
5. C115.2. Construction with a weight of 69 kg per 1 m, consists of 2 layers of cladding with a double frame. Inside there is an additional GKL. Due to the use of such technology, the strength of the structure increases by 3-4 times, it absorbs noise better and retains heat. Inside are slabs of mineral wool.
6. C116. The minimum cross section is 220 mm with a weight of 61 kg. A double metal frame and 2 layers of plasterboard are used. Inside there is space for communications - heating pipes, sewerage, concealed wiring. Fireproof panels are used.
7. C118. Heavy baffle with high security properties, can be used where there are high risks of intrusion. The weight of 1 m is 86 kg, and the height is at least 220 mm. Between the GKL in the structure on both sides, galvanized steel with a thickness of 0.5 mm is used. Drywall panels - 3.
8. C121. From this design, a light partition is obtained - 32 kg. The frame is made from wooden beam, sheathed with 1 layer of GKL. The cross section depends on the width of the timber, as well as the type of sheets used.
9. C122. The weight of the partition is 57 kg per 1 m, it is made of bars, but sheathed with 2 layers of plasterboard. Inside is insulating material from mineral fibre.

The most practical type of sheets used is GKL 12.5. This drywall is strong enough, and when combined with 2-3 layers, it makes it possible to create full-fledged walls using steel or wooden frame. From above it can be upholstered with tiles, wallpaper or treated with paint. In rooms with high humidity it is appropriate to use GKLV (waterproof).

Plasterboard partition calculation

To determine the minimum thickness of a drywall partition, it is necessary to take into account the cross-section of sheets and a rack made of metal, which is most often used to build durable and reliable structures. It is this type of profile that is taken as the basis for creating most interior partitions.

When calculating a drywall partition, you also need to consider how many layers there will be in the structure, single or double metal is used. If we take as a basis the classic version of drywall and a 100 mm rack, recognized as strong and reliable enough, the following results will be obtained.

Drywall thickness

The ideal thickness of a drywall sheet, recognized by all builders, is 12.5 mm. If you reduce the indicator, you can face serious problems regarding the strength of the building. If the dimensions of the GKL for the partition are taken smaller, there is a high risk that they will deform over time.

So, based on the selected drywall thickness for the partition, you can calculate the load level:

• if a load of up to 50 kg is expected, then GKL should be chosen 12.5;
• if the load is above 50, but less than 70 kg, you can use double GKL or 18 mm sheets;
• if more than 70 kg, then double or triple GCR is also installed.

Hanging shelves do not give a serious load, as well as hooks or hangers. If intervention is provided for in the design to create niches in which heavy objects will stand, the strength of the product also increases.

Thickness of uprights

For the construction of the frame, a rack-mount profile is used. It is suitable for the construction of walls that perform a purely decorative function, if you choose a 50 mm metal rail. For more serious buildings, a profile 100 frame is suitable.

Advice! For erection decorative partition, which is not threatened by mechanical influences or high pressure, you can use thin metal slats 50, but you do not need to reduce the cross section of sheets for it.

If the design involves the use of heavy hinged parts or a door is mounted in it, the profile should be 100. Not only the thickness of the partition, but also the reliability depends on it:

• buildings made of metal slats are more reliable and durable;
• you can increase the layer of insulating material, increasing the protection of the room from extraneous noise;
• due to the frame, strength increases, for this you do not have to use an increased number of sheets;
• wide metal provides correct work doors.

Soundproofing material in partitions can be used in several types. Optimal - mineral wool or sheets. This material has a low price, complies with all building codes and helps to retain heat.

If you lay soundproof tapes under the metal, they will increase the quality of the building.

How to calculate the thickness of a wall partition

When calculating the minimum thickness of a drywall partition, many parameters must be taken into account. Will it have sound insulation, what profile is used, how many sheets for upholstery - all this increases the cross section by 1-2 cm. As a result, the design can be no more than 8 cm, or more than 15 cm.

If the main goal of building a partition is to save space, then thin metal 50 and GKL sheets 12.5 are used. If there is no choice at all, and you need to make the cross section even smaller, choose sheets of 9.5 mm, but experts do not advise doing this.

Fold up size metal rail with a total sheet thickness (9.5 or 12.5 mm): 50 mm profile + 9.5 and 9.5 mm = 69 mm when using the thinnest sheets. When using classic GKL 12.5 mm, the width increases by 6 and is equal to 75 mm.

The minimum section of the sheets can only be used if the installation of doors is not provided. Also, this type should not be selected if the wall is placed in a place where, optionally, a person can hit his elbow or fall in this space.

If the wall must be strong, but at the same time it is necessary to reduce its cross section as much as possible, use profile 50 and double skin on one or both sides. Here's how you can strengthen the frame in this case:

• use the trampled connection of the rack profile in a step of 60 cm between them;
• add bars 5 by 5 cm in cross section, inserting them into the racks;
• reduce the distance between the vertical ribs of the frame support to 40 cm.

The thickness in this case, with double-sided sheathing with one layer of GKL, will be 75 mm, and if sheathed with two layers of canvases, then 100.

Adding noise isolation

If a sound insulation layer is used inside, or it is planned to carry out plumbing, electrics, sewage, then use an expanded profile of 100. If the strength should not be high, use ordinary plasterboard sheets with a single-layer frame sheathing, as a result: 100 profiles + two sheets of 12 each, 5 = 125 mm finished wall.

If you need to maximize the level of noise absorption, then a strong layer of cotton wool is laid inside, and the frame itself is made double. To do this, put a 50 profile in a step of 5 to 10 mm from each other. Under the guides of the structure they put damper tape- up and down.

The frame is filled with mineral wool 60 x 10 cm. The structure is sheathed with 2 plasterboard sheets on both sides. The result is the following thickness: 2 frames of 50 mm each, a gap of 5, 4 plasterboards with a 2-layer sheathing of 12.5 = 155 mm. If the gap is increased to 10 mm, then the wall size will be exactly 160.

What is the total thickness of the structure for walls

Wall thickness internal partitions depends on the sheets used, metal racks, design decor. Additionally, during the construction, decorative structures and fasteners are taken into account, which increase the thickness by an average of 4 mm. So, a standard wall of 100 profiles and a single-layer sheathing on 2 sides of 12.5 GKL with the addition decorative elements will be approximately 130 mm in thickness. If sheathed with acrylic panels or tiles, add another 5 on each side at least, resulting in 140 mm.

It happens that an arched profile 65 is used for construction, as well as thin sheets of GKL 9.5, 1 layer on 2 sides. In this case, the thickness is 84 mm, excluding decorative elements. But, as noted above, the construction of partitions from sheets of 9.5 or less is impractical: their cost differs slightly from thicker sheets, while the strength characteristics are much lower.

Advice! If there are a lot of 9.5 panels left from any other work, you can make a double cladding of the frame. In this case, the thickness of 1 side is 19 mm.

The thickness of refractory and waterproof plasterboards may not differ from 12.5 standard panels. The only difference between them is the shade. So, GKLV have a green color.

Determination of the thickness of the drywall partition

To determine the total thickness of drywall partitions, the following must be considered:

• the use of a profile for 50, 65 or 100, as well as the number of profile structures (for example, a double 50 profile has a gap of 5-10 mm, which affects the total thickness of the erected product);
• to increase the overall rigidity, 2-3 layers of plasterboard are used, which increases the thickness by 12.5 mm of each layer when using standard panels;
• decorative designs can have one layer of coating on one side.

If we talk about the main characteristics of structures, we can distinguish 3 types. The first - 75-150 mm partitions C111 with a profile of 50 co standard sheets. If double cladding is used, this adds 25 mm to the total thickness.

The second type - C113 - 150-175 mm structures with a frame made of a 100 mm profile. With a three-layer coating of GKL 12.5, the thickness reaches 175 mm.

And the third type - thick walls with a double frame 175-250 mm. In the first case, you can use a profile 65-75, in the second - 100 mm. Communications are laid in such constructions.

Should I specifically buy arched drywall 6.5 or 9.5? Most builders agree that it's better to add some money and buy normal 12.5mm blades. This will not greatly affect the reduction of space, but will significantly improve the quality.

Determining the thickness of drywall partitions is a simple process. It is necessary to take into account only 3 components: the profile used, the GKL panels and the number of their layers, as well as the number of profile sections, which can be 2 or 1. Then there are simple operations of adding all the components, taking into account decorative coating. In order not to make mistakes with the calculations, you should not place a partition 1 cm from furniture or other structures. If you leave a distance of 3-5 cm, you can avoid any trouble during installation.

Houses 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 interior partitions

Various kinds of SNiP standards were developed primarily for the construction of multi-storey buildings. However, many owners of suburban allotments 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 also applies, of course, 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 provide sound insulation of shared rooms by 40-50 dB. That is, this parameter will depend primarily on what material is supposed to be used for the construction of the structure.

Thickness of wooden partitions

Most often for premises for various purposes country low-rise houses are divided 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 section of at least 100 x 100 mm can provide the level of sound insulation required by SNiP.

However, such a thick material for assembling partitions in country houses rarely used, of course. A partition erected using such a beam will take up quite a lot of space in the building. In addition, the cost of a beam directly depends on its cross section.

In most cases, the owners country houses collect frame partitions using a bar 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 the interior is usually 10 cm. This is explained design features most used building material. The width of a standard brick is exactly 10 mm. Partitions are erected, usually according to the “half-brick” method.

According to SNiP standards:

the thickness of the masonry joints in the partition should not exceed 12 mm;

when laying, dressing is mandatory;

erecting brick partitions is allowed only on a solid foundation.

Plasterboard constructions

When using such material, the thickness of the interior partition will also be fixed. Plasterboard partitions are assembled in most cases using a standard profile. AT different situations the thickness of such structures can be equal to:

75, 100 or 125 mm when using a conventional profile and sheathing in one sheet;

100, 125, 150 mm for sheathing in two sheets;

155, 205, 255 mm when using a double profile and sheathing in 1 sheet;

more than 220 on a double profile with a 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.

The thickness of interior partitions from and foam blocks

In this case, laying 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 foam or gas block. How many options exist standard sizes similar 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 most compact version this material. 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

Constructions of this type are used by summer residents and owners of country houses. residential buildings very popular in the first place, due to their cheapness. Also, the advantages of partitions of this type include:

ease of installation;

ecological cleanliness.

Very often, for sheathing separating structures of this type, not the usual edged board, and lining. In this case, the partition does not require additional finishing and is aesthetically very attractive.

The advantages of frame-panel structures, therefore, have a lot. 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, can only be installed in compliance with certain rules. 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 ones. 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 GKL structures

The thickness of the 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 GKL.

Like frame-panel, such structures have two more main advantages - ease of assembly 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 cleanliness, such material is inferior to boards, of course.

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, they 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, an expansion gap is necessarily provided.

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 markings;

in those two walls that the partition will subsequently connect, vertical grooves are made;

spikes are cut in the timber prepared for the extreme racks;

racks are installed to the walls with the assembly of the "castle" and are additionally fastened with nails or self-tapping screws;

using corners, intermediate racks are installed;

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).

Brick wall laying

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 owners of the house decided to make an interior partition made of bricks, the masonry mortar for such a structure is mixed from cement and sand in a ratio of 1/3. In order to give the mixture plasticity, masons usually also add a little slaked lime to it. Before laying, the bricks are put dry and the row is leveled. Further, the assembly of the wall is carried out 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. Work begins in this case in this way:

perform marking on the floor;

make notches in concrete and moisten it with plenty of water;

a strip of mortar 20 mm thick is applied to the floor;

lay out the first row of bricks with tapping with a hammer to obtain a bottom seam 10-12 mm thick;

laying according to standard technology.

Block structures

Approximately according to the same technology as brick, foam and aerated concrete partitions are being 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

The standard thickness of interior partitions of this type is 100-150 mm. The assembly of GKL structures in most cases includes three stages:

installation of a frame from a profile;

installation soundproofing material;

GKL sheathing.

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. Elongation is carried out using additional sections of the profile.

The rules for the installation of frames under the GKL are observed as follows:

riser profiles are inserted into the ceiling guide by 2 cm;

pre-vertical elements lead into the lower horizontal profile;

the racks adjacent to the wall are pasted over with a 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. 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 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 GCR, holes for pipes, for example, heating systems, are usually provided initially. In a bar, when assembling 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.
