Drywall: price per sheet, sizes and varieties of material
Drywall is one of the most popular building materials. The main advantage of the material is that its use allows you to expand the range of design solutions and create designs of various shapes, finish walls and ceilings in any room. This article discusses the parameters that allow you to choose the right drywall: the price per sheet, dimensions, thickness, purpose and others.
What is drywall made of?
The main material that is part of the drywall sandwich is gypsum. It is a natural salt that is formed naturally from seawater.
In order to obtain a drywall sheet (GCL), the extracted raw materials must undergo pre-treatment, which includes two processes:
- firing. The temperature at which such a process takes place is approximately 180-190 ° C;
To make a GCL of the desired shape, a solution with water is mixed, sometimes fiberglass is added. It is a component that significantly increases the deformation resistance of GCL, and also has a positive effect on the refractory qualities. Cardboard is fixed on both sides of the gypsum sheet, which is environmentally friendly. Such cardboard is made from cellulose and impregnated at the production stage with special flame retardants.
The main types of plasterboard sheets
Depending on the purpose and technical features , all GCL are divided into the following types:
- moisture resistant;
- waterproof and fireproof;
Standard and moisture-resistant plasterboard sheet of 12 mm. Price per sheet and characteristics
The standard GCL is used when it is necessary to perform interior finishing work. With the help of standard GCL, walls are leveled, as well as partitions, multi-level ceilings, etc. are arranged. To calculate materials for finishing work, it is necessary to know the length and height of plasterboard sheets. The dimensions of the sheet are usually 2500x1200mm. The cardboard of standard sheets is gray in color and is indicated by blue markings. Standard GCLs are used in rooms with normal humidity.
Moisture-resistant plasterboard sheets are used in rooms where the humidity level exceeds the permissible values. But its use is advisable only if an exhaust ventilation system is provided in the room. In turn, the front surface of the sheet should be provided with waterproofing material (paint, primer, PVC coating).
The dimensions of the moisture-resistant drywall sheet are the same as those of the standard GCL. Such sheets are used for the construction of slopes. GCLV in combination with waterproofing materials are used for covering work surfaces in rooms with high humidity levels. These include the bathroom.
Useful information! Moisture-resistant drywall is characterized by increased strength; it can be used for finishing public premises.
The material includes various hydrophobic additives, thanks to which the sheet is able to absorb a minimum amount of moisture (no more than 10%). In this case, the sheet has a green color and is indicated by a blue marking. The price and size of a moisture-resistant drywall sheet may be different. However, products of standard sizes (2500x1200x12mm) cost from 295 to 395 rubles per sheet.
Fire-resistant, water-resistant and acoustic drywall
Refractory construction products are used when it is necessary to finish a surface that is located in close proximity to a fire source (for example, the inner surface of a fireplace). This is exactly the option in which fiberglass is mixed, which gives resistance to fire.
Refractory sheets are used in rooms where the humidity level may be low or normal. Cardboard in this case can be both pink and red. Plasterboard refractory sheets have red markings.
Water-resistant and fireproof plasterboard sheet (GCLVO) has a high coefficient of fire resistance, and also has a reduced water absorption. The combination of properties allows the use of such plasterboard sheets in baths and steam rooms. However, it can also be used for ordinary interior finishing works. The cardboard of the GCLVO sheet is distinguished by green color and red marking.
Acoustic GCL differ from other varieties in that it has a high coefficient of sound insulation. This property allows you to use this material for finishing walls and ceilings in concert halls, dance studios, as well as rooms where sound recordings are made. The main difference between acoustic drywall and standard is that its surface has holes, with a cross-section index of about 1 cm. The reverse side of the acoustic GCL is equipped with a coating that perfectly copes with the absorption of sound waves.
Dimensions of drywall sheets: length, height and thickness
The standard length of the GCL is 2.5 m, and the width is 1.2 m. Also, the following sizes can be attributed to the standard length: 3 and 3.5 m. In addition to standard sizes, plasterboard sheets can be found in markets and in hardware stores, the length of which can be 4 m. Sometimes there are sheets with a length of 1.2 m (small-sized). The sizes and prices of drywall are interrelated. For example, sheets with a thickness of 9.5 mm are cheaper than twelve-millimeter products.
The standard width of a drywall sheet is 1200 mm (1.2 m), however, there are products on sale in which this indicator can be 2 times lower (625 mm). Such sheets will cost less.
As for the thickness of the GCL, the standard indicators include the following:
- 12.5 mm;
- 9.5 mm.
Deviation from the thickness standard is also a common practice. If necessary, you can purchase a 6.6 mm thick GCL. In this case, their mass will be much lower, as well as the indicator of the cost of drywall per sheet. There are also sheets with a different thickness — from 8 to 24 mm, which allows you to significantly expand their operational area.
Differences between wall and ceiling drywall
The dimensions of the wall drywall in the form of sheets may be different, however, they are all considered standard. The length of the wall GCL varies from 2000 to 4000 mm. The minimum width is 625 mm, and the maximum is 1200 mm. The standard thickness of drywall, which is used for wall cladding, is 12.5 mm.
Pay attention! For wall decoration, sheets are most often used, the dimensions of which are 2500x1200x12.5 mm.
If it is necessary to sheathe the walls in an apartment or house with high ceilings, then it is recommended to use sheets with the longest length (4 m). Thus, it can be concluded that the dimensions of the GCL are selected depending on the specific situation.
Drywall, which is used for ceiling mounting, itself should be lighter in order to simplify the installation process as much as possible. For ceiling cladding, GCL with a thickness of 8 or 9.5 mm is used. The minimum thickness allows you to reduce the weight of the suspended ceiling, which in turn allows you to reduce financial costs when purchasing profiles for fixing drywall.
The price of a plasterboard ceiling is significantly lower than in the case of wall material installation. If necessary, you can use the services of professionals who charge about 250 rubles on average. for the installation of 1 square meter of ceiling drywall. The price per m2 of drywall installation on the wall and ceiling also depends on the complexity of the work.
Overview of the cost of installation of GCL:
|Installation of drywall on the wall. Price per m2||Installation of ceiling GCL, m2||Installation of drywall partitions. Price per m2|
|260-380 p||250-270 p||480-660 p|
The price per m2 of installation of drywall partitions is calculated depending on the number of layers of drywall (1 or 2), as in other cases. Thus, it can be concluded that the prices per sq. m. of drywall installation differ depending on the installation location, the complexity of the work (including the creation of figured elements), the number of layers of gypsum material, etc.
In order to answer a common question: how much drywall sheets weigh, it is necessary to familiarize yourself with the data presented below. The table below shows the dependence of the weight of the GCL on their dimensions.
The dependence of the weight of the GCL on the dimensions:
|Dimensions of GCL, mm||Thickness of GCL, mm||Weight, kg||Average cost, rub.|
Pay attention! The weight of the 12.5 mm drywall sheet is indicated for a reason. Such sheets are in the greatest demand among buyers.
Features and advantages of KNAUF drywall
KNAUF drywall is the most common material used for interior decoration of walls and ceilings. In many ways, its popularity is due to its high quality characteristics.

Thus, KNAUF plasterboard sheets are the undisputed leaders in sales and are recommended as the main material for wall and ceiling cladding.
How much does drywall cost: an overview of types and prices of different modifications
Every person who is going to use GCL for the interior decoration of his house or apartment, first of all it is necessary to study how much a sheet of drywall costs. The prices that can be found on the Internet vary depending on the brands and sizes of GCL. The price can be specified both per square meter of material and for a full sheet.
To date, there are quite different, in terms of cost, plasterboard sheets. If desired, you can buy very cheap products, the price of which will be no more than 150 rubles per sheet. Inexpensive drywall will save on repairs, but you need to understand that when buying cheap material, you should not hope for high quality products. After all, the quality of any building material directly depends on its price. You can buy drywall in sheets with high quality standards from 230 to 250 rubles per piece.
As mentioned above, the price of this finishing material also depends on the manufacturer’s company. For example, the price of KNAUF drywall is slightly higher than in the case of other brands. For example, the cheapest sheets from this German manufacturer cost from 220 to 240 rubles per piece. More expensive GCL from the KNAUF brand can be purchased for 300-340 rubles.

The price for a sheet of moisture-resistant drywall from domestic manufacturers is more democratic, due to the lack of need for expensive transportation. But in order to purchase high-quality material, you need to pay attention to the price per sheet. You can buy moisture-resistant drywall from a domestic manufacturer for at least 300 rubles. (1 sheet).
Heat-resistant drywall is used for covering surfaces located in the immediate vicinity of the fire source.

Profiles for drywall: sizes and prices
Today you can find different profiles for drywall. The size and cost of these products also vary. The thickness of the metal profiles from the German manufacturer KNAUF ranges from 0.5 to 0.8 mm. The ability to choose different thicknesses allows you to assemble frames that are able to withstand the required weight.
Useful information! Profiles for drywall at the production stage are equipped with corrosion protection by galvanizing. This procedure makes it possible to strengthen their strength properties and extend the service life as a whole.
Profiles can have different designs, which allows you to perform construction models of any configuration. Depending on the design features, all profiles are divided into several varieties.
Length of profiles of different types:
|Product Name||Length, m|
|Corner||up to 6|
Rack profiles: description, usage and prices
In the international nomenclature of building materials, such products are designated by the Latin letters CW. Such profiles are most often used for the installation of metal crates. Metal crates are necessary for fixing the GCL on false walls or ceilings.
The algorithm for using rack profiles is as follows:
The structure made of profiles is the basis for further installation of the GCL. The slats, which belong to the rack type, are made with a width of 60 mm, and their height is 27 mm. The length of the rack bar can be different (from 2 to 6 meters).
If the length of the bar does not correspond to the set goal, then it is possible to combine two or more bars together into one profile. The docking of individual slats with each other is carried out with the help of special locking elements. If desired, the slats can be connected in such a way that they are perpendicular to each other.
Such profiles may have different markings, depending on the manufacturer. The marking of the rack slats can be as follows:
- CD (KNAUF);
- PP (Giprok).
The price of the profile for drywall rack type varies from 150 to 400 rubles per package. The spread of prices is due to different brands of the product, as well as dimensions. Packages most often contain a standard number of parts (12 pcs.).
Average cost of rack profiles:
|Profile size, mm||Price, rub.|
The profile of this type has the international designation UW. These products are made in the shape of the letter “P”. From the name it can be concluded that such products are used as guiding elements. When assembling the frame structure, racks or guides are fixed to them, after which the drywall is installed. Prices for guide profiles vary depending on the length of the product.
The width of the guide rail is from 28 mm, and the height is from 27 mm. Fixing the guide bars to the working surface is done with dowels. The length of the guide part can be different (from 2.5 to 6 m).
Average cost of guide profiles:
|Profile size, mm||Price, rub.|
Ceiling and arched profiles
The international designation of the ceiling profile is CD.Ceiling slats are used for quick assembly of frame structures, which are fixed to the ceiling and subsequently sheathed with GCL.
The thickness of the ceiling slats varies from 0.45 to 0.55 mm. The standard length of the ceiling profile is 3 m. The most common ceiling slats with dimensions of 60×27 mm.
Average cost of a ceiling profile:
|Profile size, mm||Profile length, mm||Price, rub.|
The variety of arched slats differs from the rest in that they have a curved shape. Arched slats are used for the organization of arched openings and other structures with a complex shape.
Such products are marked with Latin letters CD and UD. When installing such parts, it is possible to bend them along the required radius. This possibility is realized due to the fact that the body of this type of profile is provided with holes and incisions at the manufacturing stage.
In the building materials market and in specialized stores, you can often find ready-made (curved) profiles. The bending radius of such a profile can vary from 0.5 to several meters, and the length from 2 to 6 m. Profiles of this type have a fairly large price range. You can buy a profile for arched drywall for both 30 and 200 rubles. The design feature of the part plays a very important role here.
Useful information! It often happens that a profile with the required radius is not found on sale and even straight arched models with notches are absent. In this case, experienced craftsmen advise you to make notches on a regular profile and make a bend of the desired radius yourself.
Products of this type are divided into two types:
The first type of corner slats is used to ensure the protection of the outer corners of plasterboard structures (for example, in doorways). The corner bar is fixed due to plaster, which penetrates into the holes of the profile and securely fixes it in the required position. The second type is also called beacons and is used for plastering walls.
The cost of popular models of angular profiles:
|Product size and name, mm||Price, rub.|
|Aluminum perforated corner profile, 20×20, 3000||27|
|Corner galvanized mesh profile 35×35, 3000||39|
|Corner profile white PVC, 30×30, 3000||63|
|Corner protective profile, 31×31,3000||129|
|Metallized paper-based corner for internal corners, 3050||260|
As a rule, when assembling drywall structures, experienced craftsmen try to use materials from the same company. For example, Knauf profiles for drywall, of which there are many types and sizes, are purchased for fixing the Knauf brand GCL. There is no point in using expensive drywall, but saving on the profile, because the durability of the entire structure depends on the quality and reliability of the parts for the frame. And in order not to exceed the budget limit allocated for repairs, you need to carefully calculate the amount of materials, choose the optimal size of sheets to minimize the amount of residues.
