Profile consumption per 1m2 of plasterboard partition. Calculation of plasterboard partitions (GKL): calculator

In terms of its structure, a plasterboard sheet is a rectangular structure consisting of a gypsum core covered with cardboard on both sides. Drywall is classified as environmentally friendly pure materials, has good performance qualities, thanks to which it is actively used in “dry construction”.

Structure of a plasterboard sheet: 1- gypsum base, 2 - sheets of drywall.

Thanks to its clear geometric dimensions, it is not difficult to calculate the consumption of drywall per 1 sq.m. When choosing a material, it is necessary to take into account its purpose for installation in certain conditions.

Of the total mass of this material, gypsum accounts for 93%, cardboard takes up 6%, and another 1% remains for starch and moisture. In the construction of a plasterboard sheet, only cardboard is susceptible to fire. And then, due to the lack air gap between cardboard and plaster, the paper does not burn, but smolders. Certain types sheets have good flexibility; drywall maybe soundproofing material provided that the frame is properly arranged and the seams are properly sealed with high-quality putty. Consumption building materials when using drywall is related to its type and technology of application. Today, the products of the two largest manufacturers are mainly used, each of which uses its own marking to indicate the type of material.

Classification according to Knauf

  1. GKL. This is a rectangular “piece” of plaster, covered with cardboard on 4 sides.
  2. GKLV. Moisture-resistant drywall, intended for use in rooms with high humidity. The cardboard used in production undergoes a treatment that reduces the possibility of the formation of mold, fungi and other similar microorganisms. To be able to distinguish moisture resistant material Unlike usual, green cardboard is used for pasting gypsum boards.
  3. GKLO. This drywall has increased resistance to high temperatures. Used where available high requirements to fire safety.
  4. GKLVO. The material is fire-resistant and at the same time has increased resistance to moisture penetration.
  5. GVL. Gypsum fiber sheet, which is a pressed non-flammable mixture of crushed paper and gypsum.
  6. GVLV. Drywall with increased resistance to moisture.

First four types plasterboard sheets are actively used in construction during the construction frame partitions, wall cladding, ceiling lining. GKLV can also be used as additional insulation. The last two types of drywall from the above list are used:

  • in basements where humidity exceeds 70% (for arranging floors, walls with subsequent laying of tiles);
  • in sanitary premises;
  • in utility rooms, storerooms;
  • in attics and attics;
  • in ordinary residential premises.

When calculating the need for plasterboard, it is necessary to take into account its standard dimensions and the height of the room in which the gypsum plasterboard is supposed to be installed. The Knauf company produces standard sheets:

  • width 1.2; 0.5 m;
  • length 2.5 m;
  • thickness 16, 14, 12, 10 mm.

Classification of drywall according to “Gyproc”

The company produces sheets with lengths of 3.6, 3.3, 3, 2.7, 2.6, 2.52, 2.4 m and widths of 1.2, 0.9, 0.6 m. The company specification in the designation takes into account special properties plasterboard sheet and its thickness:

  • GH13: normal;
  • GNI: moisture resistant;
  • GTS9: waterproof and windproof;
  • GEK13: with increased strength;
  • GF15: fire resistant;
  • GN6: restoration (restoration) or repair.

Calculation of the total mass of 1m2 plasterboard partitions

It is usually carried out not only to find out the expected consumption of material, but also to find out the level of load that the structure will create. The approximate calculation below is valid for standard sheets GKL, having a thickness of 12.5 mm and used for covering partitions with a metal frame.

  1. The weight of 1 “square” of a partition up to 5 m high, the frame of which is sheathed on both sides with only one layer of gypsum board, is about 25 kg. When arranging partitions of greater height, a thicker profile is used, so the weight of 1 sq. m will be higher.
  2. If a partition with a single frame is covered with two layers of plasterboard, then the weight of 1 square meter at a height of up to 6.5 m will be approximately 45 kg.
  3. When constructing a double frame and covering it with gypsum boards in 2 layers, the weight is 1 sq. m increases to 48 kg.
  4. If you plan to build a double frame with space for laying communications, then the mass is 1 sq. m will be 49 kg (with a height of up to 6 m).

When constructing a wooden frame, the mass is 1 sq. m decreases. But when using wooden blocks, the height of the partition usually does not exceed 4 meters. When constructing a structure with one layer of plasterboard fixed on both sides, the mass is 1 sq. m will be less than 30 kg. If the frame is sheathed with two layers of gypsum board, then the weight of 1 “square” will be 50.5 kg. Knowing the total mass of the partitions, you can calculate the load on the floor, which is important, for example, when arranging an attic. When preparing drywall for further finishing, any homeowner will be forced to calculate the consumption of other materials, in particular, primer and putty. They are the main finishing material when using drywall.

Construction plasterboard structures begins with the design and calculation of the quantity of purchased material. It’s easy to find out the number of profiles and gypsum boards, but determining how many fasteners will be required is more difficult. Let's find out how to count the number of screws per sheet of drywall.

What kind of screws are used when installing gypsum boards?

To fasten drywall to the frame, screws of different lengths are used:

  • 25 mm – when installing plasterboard in one layer;
  • 35 mm – with two layers of sheathing.

The type of screws is selected based on the frame material:

  • the cladding is attached to the profile with metal screws;
  • to the beam - on wood.

It is easy to distinguish them: hardware intended for working with metal have more frequent threads.

You should not use one type of screws instead of another: this will certainly affect the strength of the fastening.

The design of the fastener ensures convenience and quality of work:

  • Hardware is protected from corrosion by a special coating that gives it a black color.
  • The pointed spiral of the thread ensures easy penetration of the self-tapping screw into the metal profile and reliably holds it there in the future.
  • The conical head is recessed into the material and does not interfere with subsequent finishing.
  • Deep cross slot it allows you to screw in a self-tapping screw with a regular screwdriver or screwdriver.

When using a screwdriver, you need to act carefully: there is a high risk of sinking the screw too deep and damaging the material. Makes work easier: due to its design, it limits the depth of screwing in the hardware.

Professionals use . They make the process of installing drywall sheets much easier and faster. But the cost of such a tool is high, so there is no point in purchasing it for a single repair.

Before calculating how many self-tapping screws will be needed for a structure, it is logical to familiarize yourself with the norms and rules for their placement. The following nuances are taken into account:

  • The distance between adjacent screws must be more than 10 cm, otherwise the plaster of the sheet will begin to crumble when screwed in.
  • When leveling walls or installing partitions, a step of 25–35 cm is taken between the attachment points. It is reduced to 15–20 cm if in the future it is planned to cover the surface with heavy material, such as ceramic tiles.

HELPFUL INFORMATION: How to make a plasterboard ceiling with your own hands: marking, assembly, finishing

  • More hardware is used for the ceiling sheathing, since they are attached more often: the step is 15–20 cm. The rule works here: the thicker and heavier the drywall, the smaller the distance between the attachment points.
  • When installing in two layers, the first one is attached less frequently - every 45–60 cm. The screws that secure the second layer are 10 cm longer. When screwed in, they additionally secure the first one. This reduces the consumption of hardware and eliminates unnecessary costs.
  • The number of required attachment points increases during construction curved structures. Here the pitch between the screws is chosen so as to fix the desired surface shape.

Calculation of the number of screws

It is produced according to the frame diagram drawn up. It is clear that the number and dimensions of the guides, as well as the jumpers between them, will be individual for each case. General recommendations the following:

  • For walls, the distance between the guides is 40 or 60 cm. This step allows you to place the joints of the sheets on the surface of the profile.

  • The number of horizontal jumpers depends on the dimensions of the room (one sheet of drywall is often not enough in height), as well as on the requirements for structural rigidity (mandatory when constructing partitions, but can be neglected when leveling walls).
  • For ceiling structures, frames are constructed in the form of cells with dimensions of 40 × 40, 40 × 60 or 60 × 60 cm. This structure ensures a minimum of trimmings and joining of elements on the profile.
  • 11 self-tapping screws for each rack (the sheet is positioned vertically, its length is 2,500 mm, the fastening pitch is 25 mm).
  • For 4 racks – 44 screws.
  • Plus 6 - for fastening to the upper and lower horizontal jumpers (three for each - just place one self-tapping screw between adjacent vertical posts).
  • In total, 50 pieces will be needed per sheet.

Online calculator for self-tapping screws on a sheet of drywall

In order not to do manual calculations or test yourself, it is convenient to use our calculator, which calculates using the Knauf formula.

Calculator for calculating plasterboard on walls. Online calculator consumption of plasterboard on walls, calculation of components for installing plasterboard on the wall.

Plasterboard structures are used for almost any repair, and especially often for interior decoration walls With its help, you can level out unevenness of several centimeters, which is very difficult to achieve using ordinary plaster. Sometimes in private houses the walls do not stand strictly vertically, but slightly inclined. It is easier to achieve verticality in this case using gypsum plasterboard or gypsum plasterboard sheets. The result will be Smooth surface, suitable for any finishing. Drywall is installed very quickly and is inexpensive.

When starting to select materials for finishing, it is recommended to use drywall consumption calculator for walls. With its help, the likelihood that building materials may not be enough, or there may be more than needed, will be minimized.

The drywall consumption calculator for walls will approximately calculate the amount of material required for each wall and for the entire room as a whole. The exact quantity can only be obtained by using a floor plan of the room with the dimensions of the door and window openings indicated on it.

But approximate calculations will also be useful, since on their basis it will be possible to calculate the costs of building materials, or monitor the requirements of builders. The calculator is very easy to use. First you need to accurately measure the length and width of the wall that needs finishing, then enter the data in the form presented on the page. He will do all the calculations himself.

It is very convenient that with the help of such a calculator you can do not only calculation of plasterboard on walls, but also determine the amount of related materials, such as guide profiles, putty materials, fasteners, and others.

Thanks to high technical and operational parameters plasterboard is a universal building material that is used for finishing walls and ceiling surfaces. Drywall is non-toxic and non-conductive electricity, suitable for the implementation of various design ideas. Having experience in carrying out repair and construction work, you can install GC sheets on the ceiling and walls on your own. When planning the finishing of the gypsum board ceiling surface, it is necessary to correctly calculate the amount of material used, calculate the optimal profile consumption per 1 m2, drywall. The gypsum board ceiling is fixed to load-bearing frame, can be “planted” on a wooden or metal frame.

Drywall classification

Given the popularity of drywall, the construction market offers a wide range of different kinds of this facing building material from domestic and foreign manufacturers. Professionals prefer products from two large, time-tested manufacturers - KNAUF (Knauf) and GYPROC.

Drywall is a material consisting of three layers, two of which are cardboard, connected by a gypsum mass (core), which has a number of useful characteristics. The core provides protection from moisture and fire. The sheet can be processed polymer compounds, due to which the strength of the structure increases.

Some types of gypsum plasterboard have good flexibility, have soundproofing properties when the frame is properly organized and the seams are sealed with high-quality putty mixtures.

Important! Drywall is classified into categories depending on the place of application and technical characteristics building materials.

According to the place of application, the following types of Knauf plasterboard are distinguished:

  1. Wall. The leaf has standard parameters– thickness – 12.5 mm, length – 2.5 m, width – 1.2 m. The large thickness allows the material to be used for partitions, ceiling structures, and for cladding wall surfaces.
  2. Ceiling. It is permissible to use material for organizing ceiling structures of a standard thickness or a thickness reduced by 3-4 mm, since installation is much easier using more lightweight drywall. For lightweight gypsum plasterboards, a smaller amount of profile will be required.
  3. Arched. GK sheets are flexible enough to create complex structures various forms, arches Using the arched Knauf in interior design, you can implement various design projects.

To choose the right plasterboard for finishing the ceiling, you need to take into account the classification of the material depending on its functions. This parameter will allow you to determine the technical, performance characteristics building materials, select gypsum boards depending on the functional characteristics of the premises. High quality drywall“Knauf” has a special marking indicating its type.

Classification of plasterboard "Knauf":

  1. GKL. Drywall covered with cardboard on four sides.
  2. GKLV. Moisture-resistant drywall is resistant to the formation of condensation, mold, and prevents the colonization of pathogenic flora on the surface of the material. GKL "Knauf" is used to create ceiling surfaces in rooms with high humidity. GKLV is painted green.
  3. GKLO. Plasterboard sheets have increased resistance to high temperatures, fire resistant. They are quite heavy, so they are installed in the most fire hazardous areas.
  4. GKLVO. Fire-resistant material with increased resistance to moisture.
  5. GVL. Gypsum fiber sheet made of fire-resistant non-combustible gypsum mixture, crushed paper.

GKL, GKLV, GKLO are used to create partitions and for cladding wall and ceiling surfaces. GKLV provides additional thermal insulation. Gypsum fiber "Knauf" - perfect solution for basements, attics, rooms where the humidity level exceeds 65%.

Design of a suspended ceiling structure made of gypsum plasterboard

From a constructive point of view, a suspended ceiling made of gypsum plasterboard includes:

  1. Suspensions, profiles, fixed to load-bearing structure hardware.
  2. Metal frame, less often wooden slats are used. They are connected into a single frame using couplings and brackets. Using metallic profile, you can build a cellular, rail frame. The metal frame can be one- or two-level.
  3. Plasterboard panels fixed to the frame.

Important! Despite the fact that the cost wooden frame will be cheaper, professional craftsmen to create a reliable, robust construction It is recommended to use a metal frame.

When planning to install gypsum boards yourself, you must follow the technology, the sequence of work, prepare the necessary equipment, tools, purchase more than one type of profile, hardware (screws, screws, dowels), and reinforcing mesh.

Calculation of materials for HA ceilings

When calculating the materials needed for work, it is necessary to take into account the type, type of drywall used, area, functional features premises. As a rule, sheets are produced standard length. The material may differ in width, thickness, weight. The acceptable thickness for suspended ceiling structures made of gypsum plasterboard is 8-9.5 mm.

For correct calculations required quantity building materials per meter square area, take into account:

  • type of drywall;
  • type of supporting, supporting structure (frame, profile, hangers);
  • materials for finishing cladding.

When performing calculations of civil code per square meter, the dimensions and footage of the premises are taken into account. It is best to make a preliminary plan future design, which will allow you to make correct calculations and find out how many materials are required to create the structure. Indicate the dimensions of the room and the placement of the profile.

Guide profile quantity


To find out the required number of profiles per square meter, divide the perimeter by the length of the segments. Guides can be purchased three to four meters long.

Important! The number of ceiling profiles is calculated based on the calculation of 3000 mm per square meter of area.

How to calculate connectors, hangers for a profile

The formula will help determine the number of connectors for the profile: K= S*2, where S is the area suspended ceiling, K – number of crab connectors. For example, for a room with an area of ​​6 m2, 12 connectors will be required.

If the area of ​​the room is more than eight square meters, the calculation of the material is carried out according to the formula: K = S * 1.7.

Consumption of hardware for drywall

Fixing drywall to the supporting profiles is carried out with self-tapping screws, screws, and dowels. The screw is screwed in with a screwdriver or screwdriver. The sheets are fixed to the metal frame perpendicular to the built-in guides. The HA sheet should fit as tightly as possible to the frame. The screw and self-tapping screws are attached in increments of 30-35 cm. To enhance the strength of the structures, the spacing between the screws can be reduced to 15-10 cm. The screw is fixed so that its head is recessed by 1 mm.

Important! Self-tapping screws are placed at least 10-12 mm from the edge of the sheets, and 15 mm from the cut side. Otherwise, cracking of the building material may occur.

When calculating the number of screws, take into account:

  • size of gypsum boards, slabs;
  • hardware fastening step;
  • number of layers of drywall.

If the HA sheets are installed in several layers, the fixation is carried out in different steps. For example: the first layer is attached in increments of 50-60 cm, the second - 35 cm. One sheet will require 65-70 pieces of hardware. In the case of a two-layer structure - 110-115 pcs.

When creating complex shapes, plasterboard is attached to a metal frame of the desired shape, using a pre-prepared template, in which the sides can be made of plasterboard sheets.


Calculation of mass per square meter of partitions from HA

This parameter will allow you to calculate how much building material is required, the level of load on the floors, created by design, which is especially important when arranging attic and attic spaces. Below is a calculation that can be used when standard sizes plasterboard sheets:

  1. If the partition has a height of five meters, the mass of one “square”, sheathed on both sides with plasterboard, will be 25 kg. If the partition has a greater height, thicker material is used to organize it; accordingly, the weight per square meter will increase.
  2. A two-layer 6.5-meter partition with a single frame will have a mass per 1 m2 of approximately 40-45 kg.
  3. If the partition is built on double frame, there is a gap for engineering communications, a square meter will weigh 48-50 kg.
  4. When organizing structures with one layer of HA, one square meter will have a weight of 30 kg.

The weight increases if a metal frame was used for the structure. If the frame is made of wooden slats, the weight will be less, but the partition should not be higher than four meters.

Material consumption per 1 m2 for suspended ceiling

Let us give an approximate calculation of the consumption of building materials for a structure created on metal frame from gypsum plasterboard of standard thickness:

  • guide profile – 0.8 m;
  • rack, ceiling profile – 2.3 m;
  • direct suspension – 2-3 pcs;
  • reinforcing tape – 1 meter;
  • self-tapping screw 9 mm – 4-5 pcs., 25 mm – for a suspended ceiling – 23-26 pcs.;
  • dowel, corresponding screw – 5-6 pcs.

Video: calculation of materials for plasterboard ceiling structures

The main attribute of almost any renovation, especially European-quality renovation, is plasterboard structures. And this is not surprising. Indeed, from gypsum plasterboard (GVL) it is now possible to “blind” practically any partition or ceiling. For example, for a device multi-level ceiling Drywall is most often used.

In addition, these structures are quickly erected and are relatively inexpensive. True, there is one drawback here - a rather large range. So, if you decide to independently build partitions and a ceiling from gypsum plasterboard sheets in your apartment, and at the same time comply with all technology, then you will have to stock up on more than one type of profile and screws. You will also need dowels, reinforcing mesh, putty, primer, hangers and connecting elements.

All this must be purchased in the required quantity (or with a small margin) for a given design. And for this you need to calculate required amount plasterboard and profile for the ceiling or wall (partition). Therefore, for those who want to build similar structures, it was created this page, which shows an example material consumption for the most common plasterboard structures:

  • ceiling;
  • wall structures;
  • partitions.
