What are the dimensions of drywall wall. All sizes - drywall in numbers and values

Drywall is a real salvation for those who started repairs in their apartment or private house. The fact is that such an uncomplicated type of building material allows you to instantly transform the room, depriving yourself of the “pleasure” of carrying out a series of dirty work. It is noteworthy that the independent installation of drywall is quite simple, and the speed with which all work on the installation of drywall is carried out is simply fantastically high. Naturally, before running to the construction market for this fabulous material, it would be nice to know about its main characteristics. For example, do you know what the weight of the sheet is and how many of them are needed to carry out the work you have chosen?

What is drywall?

Everything ingenious is simple! In order to create a perfectly flat surface, and this is what the material we are considering is intended for, we need two sheets of thick cardboard and a filling from a hardened mixture of gypsum with various additives. That's the whole secret of this miracle material. GKL is used everywhere: it is used to create perfectly even ceilings, walls, many make original niches in the wall that are interesting in shape, etc.

Standard sizes

A typical or standard size is as follows: length - 2500 mm, width - 1200 mm, thickness - 12.5 mm. However, the length of the sheet can vary from 2 to 4 meters, while the pitch is usually 50 mm. As for the width, the choice is small: in addition to standard products with a width of 1200 mm, there are also 600 mm. But the thickness can be different depending on the functional purpose: from 6.5 to 24 mm. Most often, 9.5 and 12 mm varieties are used. Accordingly, the weight of the sheet varies depending on its parameters.

How much does a leaf weigh?

This question is often asked by people who have had a bad experience in studying physics at school. Most likely, they are interested in mass, measured in kilograms, and not in weight, the measure of which is the notorious newtons. However, to the question "How much does a sheet of drywall weigh?" - the answer will be the following: "A standard drywall sheet 1200 mm wide, 2500 mm long, and about 12 mm thick will weigh approximately 30 kg. Accordingly, we reduce any of the parameters, for example, take a sheet of ceiling material and get a mass equal to approximately 25 kg. About 93% of the total mass is the mass of gypsum with additives. The rest is cardboard and moisture absorbed into the materials. So before you think about how to properly fix drywall, it would be nice to use one of the family members as an assistant - it is almost impossible to carry out installation alone.

Kinds

Plasterboard sheets, which are most often used during repair work, are ordinary and moisture resistant. Moreover, the properties of the material depend on the additives that are introduced into the gypsum layer. Moisture-resistant GKLV is characterized by low water absorption: two times lower than that of a conventional one. Accordingly, moisture-resistant material, the characteristics of which are best suited for installation in wet rooms, is more expensive than usual. It is often used in bathrooms, kitchens, etc. It can be distinguished from the usual one by the color of the cardboard: moisture resistant - green, for ordinary rooms - gray.

Types of material by purpose
Designation View a brief description of Cardboard color Marking color
GKL Ordinary Gray blue
GKLO With increased resistance to open flame They differ from ordinary ones by special reinforcing additives in the core material Gray Red
GKLV moisture resistant They differ from ordinary ones in special impregnated cardboard, as well as hydrophobic and antifungal additives in the core material green blue
GKLVO Moisture resistant with increased resistance to open flame Differ from the usual combination of properties of GKLO and GKLV green Red



The calculation of the required materials is carried out taking into account the area of ​​\u200b\u200bcladding and a ten percent margin. It is also necessary to pay attention to the types of drywall profiles, since each of them is used for certain types of work.

As well as its required dimensions (length, width, thickness), you should understand what this material is. Drywall is a composite material manufactured in the form of sheets having a length of 2.5 to 4.8 m, a width (which is determined by the end edge located on it) from 1.2 to 1.3 m and a thickness of 8 to 24 mm, respectively. .

The material for such a sheet is gypsum, covered with a layer of cardboard. Since gypsum is the most important component of the material, it determines its main properties (strength, density, etc.). To improve them, additional components are introduced into the composition. The role of cardboard is also an important part drywall sheet. It is used not only as a frame for the sheet, but also performs a protective function, protecting the gypsum core from various kinds of damage. Cardboard is also great for exterior wall decoration with various materials: Tiles, plasters, paints, etc. Drywall calculation, online calculator.

Together, both of these materials show very good properties, making drywall so hard and flexible at the same time, for which it is especially appreciated. But its advantages do not end there, do not forget about the following positive drywall properties:

  • good soundproofing properties for walls, ceilings and floors made of plasterboard;
  • increased fire resistance, non-flammability and lightness of the material itself, which, by the way, contributes to simple and convenient mounting drywall sheets.

It should be noted that the production does not require special costs and the drywall itself is environmentally friendly and non-toxic, has a low level of acidity (about like human skin) and radiation background. All this, as well as the ability to maintain a certain microclimate, creates a very wide area of ​​​​possible application for drywall, ranging from leveling walls, erecting partitions and finishing ceilings and ending with creating relief, repairing various ready-made structures, filling cavities and openings, erecting various kinds of compositions ( shelves, columns, skirting boards, etc.) and more. Especially when you consider that with additional processing with special means, it will become even more durable, fire and moisture resistant.

At choosing drywall place and method of application must be taken into account. In accordance with this, drywall is divided into several types.

4) Fire and moisture resistant drywall (GKLVO).

Let's take a closer look at the types above:

1) Plain drywall(GKL) which consists of gypsum dough lined with thick cardboard. Suitable for interior decoration (walls, floors and ceilings) with normal humidity levels. Gypsum board of this material is economical in production, easy to assemble and easy to transport.

2) Fire resistant drywall(GKLO). This type of drywall, which has increased fire resistance, is suitable for finishing non-residential summer and utility rooms, for the construction of partitions. As the name suggests, it provides a high enough level of fire safety that it can be used near stoves and fireplaces, for the construction of communication shafts, in which a plumbing system, an air duct system, or one of various types of cables should be installed later.

3) Moisture resistant drywall(GKLV). Most often, this type of drywall is used for use in rooms in which the level of humidity is high. Such premises include a kitchen, a bathroom, a country house (in country houses, the humidity is on average higher than in a city apartment), as well as for finishing bathrooms and similar systems. It is important to note that if the bathroom is used too often (for example, if there are too many people), then from use of drywall it is better to refuse and give preference to materials with higher moisture resistance.

4) Fireproof drywall(GKLVO). This type of drywall has both moisture-resistant and fire-resistant properties. Basically this special type of drywall Designed for repairing and correcting small damages in prefabricated structures made of drywall.

Also, drywall is divided according to its intended purpose in accordance with the coating being treated and has the following types and sizes, respectively:

1) Arched drywall, used to create stylish interior arches and various interior openings, thickness 6.5 mm. It is the thinnest, due to which it is able to bend to almost any radius.

2) Wall drywall, thickness 12.5 mm. Its thickness is optimal and is suitable not only for finishing walls and creating various kinds of partitions, niches and other similar structures, it is also suitable for leveling walls

3) Ceiling drywall, for ceiling cladding, thickness 8-9.5 mm. In fact, it is a lighter version of conventional drywall and is able to reduce the weight of the suspended ceiling, which will significantly save on the profile as a result of using a wider pitch in the suspended ceiling frame system and reduce the cost compared to others. types of drywall.

So, let's move on to the size of drywall. Size of a standard drywall sheet is 2500 mm long, 1200 mm wide and 12.5 mm thick. The area of ​​such a sheet reaches three square meters, and the weight is about 29 kg, but there are other options for these values. So, the length of the drywall sheet can vary from 2 to 3.6 m, and the thickness is in the range from 6.5 to 12.5 mm, but the width of the drywall sheet is always 1.2 meters.

These sizes are suitable for choosing drywall sheets for all kinds of needs, whether it is moisture resistant drywall or regular. The most commonly used sizes of drywall sheets are 1) 3000x1200 mm; 2) 2500×1200 mm; 3)2000×1200mm;

When installing frame structures, GKL sheets are used as the material for sheathing, which are rectangular slabs with a gypsum base and a sheath made of thick paper. Consider the classification, features of use in various conditions and determine the main dimensions of drywall.

Note that this material, according to the specifics of its application, can have different properties and is divided into several types. Features of the GKL must be taken into account, when choosing them, strictly individually for each room.

Types and sizes of Knauf drywall sheets

The world standard of materials for the production of frame-sheathing structures is the products of the German company Knauf. The company's specialists distinguish several main types of drywall sheets.

  • GKL - the common name of a building and finishing material also implies a type intended for sheathing frame structures installed in rooms with normal humidity (“dry”). The standard size of drywall is 2500x1200x12.5. The mass of such a sheet is 29 kg. It is easy to distinguish by gray cardboard and blue markings.
  • GKLV - moisture resistant drywall. Special hydrophobic additives are added to its gypsum "core", the cardboard is treated with a water-repellent composition, and the size of this type of gypsum board is the same as the previous one. Weight is also 29 kg. Differs in green color of a cardboard and blue marking.
  • GKLO - fire-resistant type. It has good resistance to open fire. Gypsum filler is fired at high temperatures and impregnated with solutions that contain reinforcing substances. The mass of a plasterboard sheet measuring 2500x1200x12.5 mm is 30.6 kg. Its front side is painted pink, and the markings are red.
  • GKLVO - combines the properties of fire and moisture resistance. This material undergoes complex processing that enhances all these qualities. With standard dimensions of the GKLVO, its weight is 30.6 kg. Differs in green color of a cardboard and red marking.
  • FIREBOARD - a special type of drywall with increased fire resistance. Such boards can withstand the impact of a flame for more than an hour without losing their technological properties. With dimensions of 2500x1200x12.5 mm, it weighs 31.5 kg. It should be noted that the thickness of the reinforced FIGHTERBOARD is 20 mm. You can distinguish such material by the red color of the cardboard and the same marking.

Of course, the geometric dimensions of drywall sheets mentioned by us (according to KNAUF) are the main values. Accordingly, it is necessary to specify what other parameters the material can have. The length of drywall boards can be 2000; 2500; 3000; 3500 and 4000 mm. The most common width is 1200 mm, however, there is also a small format drywall. Its width is 600 mm. The thickness of the KNAUF sheet depends on its type, features and purpose and can be 6.5; 8; 9.5; 12.5; fourteen; 16; eighteen; twenty; and 24 mm.

The material has a symbol (marking) that determines the properties and size of the GKL and consists of:

  • Letters denoting:
    1. Group (by flammability, toxicity, etc.).
    2. View of the longitudinal edges.
  • Numbers indicating:
    1. Drywall sheet size values ​​(length, width, thickness in mm).
    2. Compliance standard (GOST).

Features of indoor use

We have already said that ordinary GKL is used for installing frame structures and wall cladding in rooms with normal humidity. The versatility and various sizes of GKL allow it to be used both in the manufacture of various partitions and in the installation of suspended ceilings. Consider where you can apply other types of material:

  • Moisture resistant (GKLV) - can be used in rooms with high humidity - bathrooms and kitchens. The water-repellent properties and standard dimensions of this type of drywall allow it to be used as a base for ceramic tiling.
  • Fire-resistant (GKLO) - used in rooms that have special fire safety requirements. It is used in the decoration of offices and factory floors as both "wall" and "ceiling" drywall. The dimensions and properties of the material also make it possible to use it in the arrangement of the attic space of residential buildings.
  • Moisture-resistant (GKLVO) - used in rooms where high humidity is combined with high temperatures. It can be used to create frame ceilings and partitions in baths and saunas. The dimensions of the moisture-resistant drywall coincide with the parameters of the fire-resistant type. With a length of 2000 to 4000 mm, its width is 1200 mm, and the thickness can be either 12.5 or 16 mm.

Features of the use of GKL in structures

It is necessary to say a few more words about the classification of the material, depending on the features of its application in a particular frame structure.

  • "Wall" - when installing partitions or finishing walls, slabs with a thickness of 12.5 mm are mainly used. Naturally, if a structure of increased strength is required, it is necessary to increase this parameter, which can always allow a variety of drywall sizes.
  • "Ceiling" - for sheathing the frame of a false ceiling, a material with a thickness of 9.5 mm is most often used, since the use of a thicker one will significantly increase the weight of the structure.
  • "Arched" - suitable for mounting structures that have a curved shape (arches, curly partitions, etc.). To the question of what size of sheet the drywall for arches has, we will answer - it does not matter, the main thing is that its thickness does not exceed 6.5 mm. Only this parameter gives good opportunities for creating elements of any curved shape.

Having told you about the features of drywall, I would like to add - what size drywall sheets have and the type to which it belongs - of course, important factors that must be taken into account at the stage of design work. However, the main feature of the GKL is that in the rooms finished with its help, there is a special atmosphere that is most favorable for human life.

We are waiting for your feedback and comments on the topic of repair work and interior decoration. You can always ask questions to our experienced specialists and get a qualified and competent answer.

A few decades ago, builders had very little knowledge about drywall, and today no repair is complete without this versatile material. This modern coating is widely used in repair and finishing works. That is why it is worth getting acquainted with its main properties, dimensions and scope.

Material Features

GKL is a composite material made in the form of plates. The main component is plaster covered with cardboard. The raw material for the production of GKL is a gypsum core enriched with active additives that increase its density and strength. Due to this, the consumer properties of the material increase significantly, it becomes hard, but at the same time plastic.

The advantages of drywall sheet are obvious:

  • made of natural environmentally friendly materials;
  • differs in the property to maintain certain parameters of the microclimate;
  • bends well;
  • has a wide scope of use;
  • the acidity level of GCR corresponds to that of human skin;
  • has high soundproofing properties;

  • does not emit radiation, completely non-toxic;
  • has a low weight;
  • easy to mount on any surface;
  • allows you to insert lighting elements inside the structure;
  • has a fairly low cost;
  • when processed with a special composition, it exhibits great flexibility and plasticity.

GKL plates are widely used for:

  • formation of a smooth surface;
  • filling the cavities and openings formed during the work;
  • installation of partitions;
  • arrangement of niches;
  • formation of multi-level ceilings;
  • creating interior compositions - arches, columns, shelves.

According to its technical features, drywall is divided into several varieties:

  • standard;
  • fire resistant;
  • moisture resistant;
  • moisture-fire resistant.

The hygroscopic model is most often used to repair shower rooms, and combustible products are widely used in the construction of communication shafts, where water pipes, electrical wiring, telephone and Internet cables, as well as dust removal systems are subsequently installed.

GKL standard parameters

GKL sheets are of different types. GKL - ordinary drywall is widely used for sheathing ceiling frames on walls and ceilings in rooms with a standard humidity indicator. A standard sheet of a typical GKL has dimensions of 2500x1200x12.5, it weighs 29 kg. This type of sheet is covered with gray cardboard and is distinguished by blue markings.

GKLV - waterproof subtype of drywall, the active component in its composition is a special hydrophobic element, and the cardboard is impregnated with a special water-repellent solution. Its dimensions correspond to the parameters of a conventional sheet, the weight is approximately equal to 29 kg. The cardboard is painted green and has a blue marking.

GKLO - a model resistant to burning. This property is due to a special production technology - gypsum is fired under the influence of elevated temperatures and processed with a special mixture of reinforcing components. The mass of a standard sheet is 30.5 kg. The outer side of the cardboard is pink and the markings are red.

GKLVO - combines hygroscopicity and fire resistance. In the production of such drywall, raw materials undergo significant processing, which increases these two parameters. Standard sheets weigh 30.6 kg, the cardboard is green and the markings are red.

There is also a fireboard - a special type of GKL, which exhibits increased refractory properties. These plates resist burning for more than one hour and at the same time do not worsen their physical and technical characteristics. A sheet with dimensions of 2500x1200x12.5 cm and a weight of 31.5 kg has a thickness of approximately 20 mm. Cardboard and markings are made in the same color - red.

GKL parameters vary in accordance with the purpose of the material:

  • Wall is used for wall cladding, its thickness is 12.5 mm.
  • Ceiling serves to form multi-level structures, has a thickness of 9.5 mm.
  • Arched is used for the manufacture of arches, columns and niches, the thickness of such a sheet is 6.5 mm.

There is no single value for the width / thickness / weight of the GCR, only the most common parameters can be distinguished:

  • width - 600 mm or 1200 mm;
  • height - 2000 and 4000 mm;
  • thickness - 6.5mm, 8mm, 10mm, 12.5mm, 14mm, 15mm, 18mm, 18.5mm, 24mm 29mm.

It is these options that are widely represented in hardware stores. However, this does not mean at all that only a standard sheet will be required for work. If interior ideas require any special parameters, then the sheets should be ordered directly from the manufacturer, but you will have to order a whole pallet (pack). GCR parameters are determined according to SP 163.1325800.2014.

Width

As a rule, the width of the GKL is standardly equal to 1200 mm. Based on this, all risers of the frame installed for plasterboard cladding have a pitch of 400 and 600 mm. However, technology does not stand still, and in recent years, modifications with a width of 600 mm, as well as 2500 mm 2000 mm, have been on sale. Small-sized sheets are lightweight, which, of course, facilitates transportation, and even a non-professional can handle their installation.

Thickness

The thickness of the GKL sheet directly affects its scope. For example, for wall cladding and creating shelves, GKL 12.5mm is used. The thickness of the ceiling plates is less - 9 mm, but this type is quite rare on sale, so the ceiling, like the walls, is mainly sheathed with sheets 12.5 mm thick, only fewer profiles are used, and the step is 60 cm. For the manufacture of interior compositions, gypsum board 6 mm thick is used, such sheets are very plastic, they are optimal for creating arches, forming undulating decorative elements. However, such sheets do not withstand loads, so it is recommended to lay the material in 2-3 layers.

Length

Standard GKL has a length of 2; 2.5 and 3m. For ease of installation, individual manufacturers produce a sheet of 1.5; 2.7 and 3.6m. For small structures, the manufacturer can cut drywall to his customers directly at the factory.

Length often becomes a real problem during the transportation phase., therefore, drywall with a length of more than 2.5 meters is in rather low demand, respectively, it is presented on the market in a small assortment. Too long plasterboards can increase the unproductive consumption of material, for example, for a room 2.7 m long, you should not buy a three-meter sheet. This will result in a lot of clippings that are hard to use in any way.

Long options are heavier and more difficult to install, working with them requires the involvement of help, since it is rather problematic to cope on your own. At the same time, long sheets avoid unnecessary butt joints and create a perfectly smooth surface. Before you purchase a large drywall, make sure that it will go into the entrance, apartment, fit in the elevator.

Weight

When planning finishing work, you need to know exactly how much each drywall sheet weighs. This will help to correctly distribute the forces that will be required to complete all the work, as well as the ability of the structure to withstand a certain load. This is very important, as it will avoid defects and collapse of the structure in the future. The standard parameters of the GKL are 2500x1200x125 mm, while the sheet area is 3 square meters. m., such a plate weighs about 29 kg.

The usual GKL, as well as GKLV, in accordance with the standards, has a mass not exceeding 1 kg per millimeter of sheet thickness, and the GKLO and GKLVO index for each millimeter ranges from 0.8 to 1.06 kg.

1 sq. m. drywall sheet weighs:

  • 5 kg - with a thickness of 6.5 mm;
  • 7.5 kg - at 9.5 mm;
  • 9.5 kg - with GKL 12.5 mm.

It is very important before starting work to correctly calculate the load per 1 square meter of coverage. If you plan to fix something heavy on it, for example, a wall is installed under water heaters, then give preference to completely blank plates, they can handle weights up to 150 kg / m2.

What influences the size?

The choice of drywall sheet size is extremely important as it reduces the amount of material used and overall repair costs. Among the most important parameters, thickness occupies a special place, because the strength of the GKL and, accordingly, the strength and capabilities of the structure itself largely depend on it. The thickness of the sheet should be selected, focusing on the type of planned work. The standard GKL for partitions has a thickness of 12.5 mm, it can withstand 50 kg of weight per square meter of sheet without tension, however, the use of drywall fasteners is a prerequisite, and the load must not be of an impact type. Such sheets are used to form walls and decorative partitions.

If you need to mount a single large load on the wall, for example, hang an air conditioner, then in this case you can also use standard sheets of 12.5 mm. But at the place of installation of the load, additional reinforcement of the crate is required.

If you plan to fix several shelves or wall cabinets, for example, kitchen or corner decor products, then it is advisable to give preference to models with a greater thickness based on the following data:

  • A 14 mm drywall sheet can withstand a load of 65 kg / sq. m.
  • A 16 mm plate will cope with a weight of 75 kg per 1 square meter.
  • Thickness 18-20 mm is used for loads up to 90 kg/sq. m.
  • Sheet in 24mm accepts 110kg/sq. m.

If there were no thick sheets on sale, you can lay the standard GKL in several overlapping rows. This may be easier and more economical, given the low availability of thick sheets in the open market.

It is important to take into account the features of the room in which the repair work is carried out. If this is an apartment or a private house, then it is quite possible to get by with thin sheets, since the owners of the premises treat it with care and are unlikely to purposefully strike and mechanically damage it. If we are talking about industrial facilities or warehouses, then the strength of the structure comes to the fore in terms of safety, therefore, sheathing with sheets with a thickness of 14 mm or more is required here.

For the formation of interior structures, special GKL sheets with a thickness of 6 mm are used. They are plastic, bend well, so they are often used for mounting undulating decorative elements. But for arch installations, this thickness is not suitable, since it will not cope with the load. Preference should be given to denser sheets or to lay thin GKL in several layers.

If the owner of the premises plans to hang pictures on the walls, then it is worth purchasing a sheet with a thickness of 10mm. To mount a plasma TV, it is better to stop at the thickest sheet. Otherwise, the structure may collapse and the TV may break. If the wall is not subjected to load, then in this situation it is enough to limit the GKL to 8 mm.

Similarly, drywall is selected to level the ceiling and create multi-level coatings. It is necessary to know exactly what will be fixed in it, and what load will be per square meter of area. Experts recommend taking thin sheets with a thickness of 9.5 as a base point, they are lightweight, so they do not overload the floors. Such material easily withstands built-in lamps located at a standard distance of 60 cm from each other.

For conceptual multi-level ceilings, one should stop at a thinner gypsum plasterboard with a thickness of 6 mm, since the frame of this form is not so strong, and the pressure on it is higher, therefore, it is necessary to reduce the pressure on the floors to the maximum. In addition, thin plasterboards are easier to install and do not require a lot of time.

Before purchasing a sheet of drywall in a hardware store, you should make sure that it is of proper quality. Pay particular attention to storage conditions, as many vendors store material outdoors without any kind of weatherproofing or in warehouses with high levels of humidity. Constant exposure to moisture and temperature changes causes a deterioration in the technical and physical parameters of the material, which worsens its performance and in the future leads to the appearance of defects and collapse of structures.

Keep in mind that the technical conditions strictly prohibit the installation of pallets with gypsum boards on top of each other. The increased load causes the appearance of cracks, chips and deformation of the gypsum core.

It is not allowed to drag sheets of drywall over the ground or uneven surface. This can damage the top layer of cardboard, reduce the strength and durability of the material. It is the violation of these conditions that causes a large number of defective products in warehouses, and the buyer, especially when faced with the acquisition of FCL for the first time, may not even notice damage at the time of purchase.

  • Purchase products only in large hardware stores and have a good reputation and high traffic and fast turnover. There should not be stale goods.
  • Try to visit the warehouse and get acquainted with the storage conditions of the GKL. If you feel that the humidity in the room is increased, you should refuse to buy in this place.
  • When loading and delivering plates, inspect each sheet for chips, cracks, dents.
  • Be sure to control the actions of the loaders, this will serve as a guarantee of protection against damage to the goods.
  • If you plan to buy a large batch of plasterboards, then first take one sheet “for testing” - cut it with a knife and evaluate its degree of uniformity

Almost no repair occurs without the use of drywall. So what kind of material is this and what size drywall sheet is considered the most optimal?

Drywall is a building material that is used in sheathing and interior decoration, as well as for interior partitions and decorative boxes. GKL drywall sheet consists of two main elements, a core of compressed gypsum with additives and reinforcing cardboard, which is placed on both sides of the core. The material is highly environmentally friendly and does not contain impurities harmful to humans, and is not subject to fire, which also eliminates the release of harmful substances.

Classification and varieties

In order to choose the most suitable sizes of drywall sheets, it is necessary to determine the type of work and the purpose of the material. According to the classification by purpose, they distinguish:

  1. Arched drywall is used for the construction of various design structures, arches, domes, rounded walls. Possesses high flexibility, thanks to small thickness;
  2. Wall GKL, which is the most common type of drywall, is used to create partitions, lining boxes and walls.
  3. The plasterboard ceiling sheet is a lightweight version of the wall plasterboard. The material significantly reduces the overall weight of the false ceiling structure and allows significant savings on the profile, as it makes it possible to use a wider pitch.

According to the main properties, the following types of drywall are distinguished:

  1. Ordinary gypsum board (gypsum plasterboard) is the most common and is used for mounting walls and ceilings in rooms with normal and low humidity. It has high environmental properties, allows you to mount lighting of any complexity, is used for cladding and horizontal and vertical surfaces.
  2. Gypsum board fire-resistant (GKLO). It differs from ordinary gypsum board in its increased resistance to fire, achieved by adding a special additive to gypsum. This type is able to withstand up to 20 minutes under the influence of open fire. Most often, GKLO is used for wall cladding near the fireplace, in boiler rooms, in attics and in other rooms with a high probability of fire.
  3. Moisture resistant drywall (GKLV) is designed for use in rooms with high humidity, such as bathrooms, kitchens, swimming pools. The material is made with the addition of hydrophobic additives to gypsum and can be used at relative air humidity up to 85%. In addition to the gypsum component, high moisture resistance is ensured by the fact that the front of the moisture-resistant drywall is covered with a special water-repellent and waterproofing treatment, for example, primers, ceramic tiles, plastic panels or other protective coatings. Also, silicone granules are introduced into the composition of moisture-resistant drywall, which reduce the hygroscopicity of gypsum and additives.
  4. Moisture-resistant and fire-resistant gypsum board (GKLVO) - this gypsum board combines the properties of all waterproof gypsum board and fire resistance. This is probably due to the fact that the innovative composition of such a drywall sheet is capable of both taking excess moisture in the room and giving it away when the air is dry. At the same time, thanks to the special fire-resistant treatment, GKLVO is not afraid of open fire. The material is perfect for insulating chimneys, finishing emergency exits and for rooms where work is carried out with open fire. Water-resistant and fire-resistant drywall is an excellent solution for kitchen areas of restaurants, cafes or hotels.
  5. Gypsum board facade (GKLF). Well protected from the negative effects of the environment, able to withstand atmospheric changes. It is used for facade cladding of buildings of various types.
  6. High-strength gypsum board or reinforced drywall - has greater strength than conventional gypsum plasterboard. This material is widely used in new construction and major repairs. Due to its increased resistance to wear and stress, it is excellent for the construction of partitions and rooms where increased impact resistance is required. High performance is achieved through the use of a durable layer of fiberglass reinforced gypsum and multilayer cardboard. Impact-resistant drywall from the Giprok company is more durable and environmentally friendly than its counterparts. The company also produces reinforced sheets with the properties of moisture-resistant drywall.

It is also necessary to highlight special-purpose panels, which are plasterboard sheets designed for specific conditions. These include materials that:

  • provide high sound insulation;
  • due to good wind protection, they are suitable for exterior decoration;
  • have high thermal conductivity, and are suitable for lining underfloor heating systems;
  • have thermal insulation properties;
  • have the ability to shield x-rays;

In addition to the main types of GKL, other similar materials are also used in the construction industry - for example, Aquapanels manufactured by Knauf. Their core is made not on gypsum, but on a cement basis with the addition of fiberglass. The material has been widely used in the decoration of exterior facades, due to its good protection against the negative effects of external factors.

A special place among special-purpose panels is occupied by GVL gypsum fiber sheets, which differ from standard drywall in that their cores contain cellulose fibers as impurities. This gives the material additional strength, evenness and fire resistance. Due to its improved properties, gypsum-fiber material is used for outdoor work, in rooms with increased dampness, as well as for the installation of floor coverings. GVL thickness is prescribed in accordance with the requirements of GOST R 51829-2001, GVL sheets with a thickness of 10 and 12 mm, a length of 2500 mm and a width of 1200 mm are considered the most popular.

Drywall sheet size

The dimensions of the drywall sheet are prescribed according to SP 163.1325800.2014. The standard size of drywall is 2500x1200x12.5 mm, sheet area 3m2. The weight of such a GKL is approximately 29 kg. For moisture resistant drywall, the sheet size has the same parameters.

Length

In length, the standard size of a drywall sheet is 2; 2.5 and 3 m. But some manufacturers, for ease of installation, make GKL 1.5 long; 2.7; 3.3; 3.6 m. For smaller structures, the manufacturer makes it possible to cut drywall sheets to customer dimensions directly at the factory.

A sheet length of more than 2.5 meters causes inconvenience during transportation and is less in demand.

But the use of long sheets of drywall avoids butt joints and is suitable for wall cladding and ceiling installation. But if you want to sheathe the ceilings in a room with a length of 2.7 m, then it does not make sense to purchase drywall sheets with a length of 3 m. Due to the fact that there will be a lot of waste and additional assistance will be required in the installation of heavy plates.

Before buying drywall, you need to check if the sheet will go into a doorway or an elevator. In most cases, it is more expedient to use GKL of a standard length of 2.5 m, the dimensions of the sheet with such a length will be 2.5x1.2x0.125 m.

What should be the width of the GKL?

Typically, the width of a drywall sheet is a standard parameter and is 1200 mm. Based on this, the racks used for the frame have a standard pitch of 400 or 600 mm. However, modern technologies have made it possible to significantly reduce the width of drywall, now you can find lightweight small-format drywall with a width of 600mm and a length of 1500 or 2000mm. The dimensions of the small format drywall sheet make it easier to transport and install. A small width is also produced and designer drywall brand GKLD from the Giprok company, its width is 900 mm. It is also easy to transport, and the installation of the structure can be handled alone. For moisture resistant drywall, the size of the small format sheet has the same parameters.

Drywall thickness

It should be noted that the standard thickness of drywall depends on its purpose.

Therefore, the thickness of the GKL should be chosen based on the intended work.

For example, for wall decoration, creating columns and lining boxes, a common wall plasterboard is used, which has a thickness of 125 mm and can be made with additives for moisture-resistant drywall.

The thickness of the plasterboard ceiling sheet used for sheathing uneven walls, domed structures, arches and leveling the ceiling is about 9 mm. However, ceiling plasterboard is quite rare, so it is often replaced with wall plasterboard. Based on experience, a 125 mm drywall thickness is better suited for ceiling sheathing, but during installation it is necessary to use a larger number of profiles, in increments of no more than 60 cm, since 125 mm thick drywall has more weight, but at the same time it has high strength characteristics.

To create various design designs, a special GCR is used, the thickness of which is 6 mm. These sheets have great flexibility and are ideal for cladding arches and undulating structures. When installing various niches and shelves, it must be taken into account that a thickness of 6 mm does not cope well with a high load and use 2-3 layers of material.

Before you start buying drywall, you need to carefully examine the sheet for quality.

Pay attention to the storage of the material, as some sellers store the sheets outside without any protection from the weather or in warehouses with high humidity.

It is also forbidden to stack pallets with sheets on top of each other, as a high load can cause deformation of the gypsum core. It is forbidden to drag the sheets on the ground, this will damage the cardboard lining. Because of this, a lot of defective products appear in warehouses. And the buyer, who first encountered the choice of drywall, due to inexperience, may not even see defects at the time of purchase.

  1. It is best to buy drywall sheets only in large hardware stores with a good reputation and high traffic. There should be no stale goods.
  2. Before buying, you must visit the warehouse and study the storage conditions of building materials. If there is high humidity in the room, it is best to refuse to purchase GKL at this outlet.
  3. When loading and unloading plates, it is necessary to control the work of loaders. To avoid damage to the goods.
  4. It is advisable to inspect each slab and check for defects such as dents, scratches, chips.

If you need to purchase a large amount of material, it is best to buy one sheet for testing. To check it, it is necessary to cut it into strips with a knife and evaluate the uniformity of the gypsum structure. To avoid mistakes, it is recommended to take products from reliable manufacturers, for example, such brands as Giprok, Knauf, Lafarge, Rigips.

Dimensions of drywall sheets, standard dimensions of drywall sheets

oGipse.ru → Materials

When installing frame structures, GKL sheets are used as the material for sheathing, which are rectangular slabs with a gypsum base and a sheath made of thick paper. Consider the classification, features of use in various conditions and determine the main dimensions of drywall.

Note that this material, according to the specifics of its application, can have different properties and is divided into several types. Features of the GKL must be taken into account, when choosing them, strictly individually for each room.

Types and sizes of Knauf drywall sheets

The world standard of materials for the production of frame-sheathing structures is the products of the German company Knauf. The company's specialists distinguish several main types of drywall sheets.

  • GKL - the common name of a building and finishing material also implies a type intended for sheathing frame structures installed in rooms with normal humidity (“dry”). The standard size of drywall is 2500x1200x12.5. The mass of such a sheet is 29 kg. It is easy to distinguish by gray cardboard and blue markings.
  • GKLV - moisture resistant drywall. Special hydrophobic additives are added to its gypsum "core", the cardboard is treated with a water-repellent composition, and the size of this type of gypsum board is the same as the previous one. Weight is also 29 kg. Differs in green color of a cardboard and blue marking.
  • GKLO - fire-resistant type. It has good resistance to open fire. Gypsum filler is fired at high temperatures and impregnated with solutions that contain reinforcing substances. The mass of a plasterboard sheet measuring 2500x1200x12.5 mm is 30.6 kg. Its front side is painted pink, and the markings are red.
  • GKLVO - combines the properties of fire and moisture resistance. This material undergoes complex processing that enhances all these qualities. With standard dimensions of the GKLVO, its weight is 30.6 kg. Differs in green color of a cardboard and red marking.
  • FIREBOARD - a special type of drywall with increased fire resistance. Such boards can withstand the impact of a flame for more than an hour without losing their technological properties. With dimensions of 2500x1200x12.5 mm, it weighs 31.5 kg. It should be noted that the thickness of the reinforced FIGHTERBOARD is 20 mm. You can distinguish such material by the red color of the cardboard and the same marking.

Of course, the geometric dimensions of drywall sheets mentioned by us (according to KNAUF) are the main values. Accordingly, it is necessary to specify what other parameters the material can have. The length of drywall boards can be 2000; 2500; 3000; 3500 and 4000 mm. The most common width is 1200 mm, however, there is also a small format drywall. Its width is 600 mm. The thickness of the KNAUF sheet depends on its type, features and purpose and can be 6.5; 8; 9.5; 12.5; fourteen; 16; eighteen; twenty; and 24 mm.

The material has a symbol (marking) that determines the properties and size of the GKL and consists of:

  • Letters denoting:
    1. Group (by flammability, toxicity, etc.).
    2. View of the longitudinal edges.
  • Numbers indicating:
    1. Drywall sheet size values ​​(length, width, thickness in mm).
    2. Compliance standard (GOST).

Features of indoor use

We have already said that ordinary GKL is used for installing frame structures and wall cladding in rooms with normal humidity. The versatility and various sizes of GKL allow it to be used both in the manufacture of various partitions and in the installation of suspended ceilings. Consider where you can apply other types of material:

  • Moisture resistant (GKLV) - can be used in rooms with high humidity - bathrooms and kitchens. The water-repellent properties and standard dimensions of this type of drywall allow it to be used as a base for ceramic tiling.
  • Fire-resistant (GKLO) - used in rooms that have special fire safety requirements. It is used in the decoration of offices and factory floors as both "wall" and "ceiling" drywall. The dimensions and properties of the material also make it possible to use it in the arrangement of the attic space of residential buildings.
  • Moisture-resistant (GKLVO) - used in rooms where high humidity is combined with high temperatures. It can be used to create frame ceilings and partitions in baths and saunas. The dimensions of the moisture-resistant drywall coincide with the parameters of the fire-resistant type. With a length of 2000 to 4000 mm, its width is 1200 mm, and the thickness can be either 12.5 or 16 mm.

Features of the use of GKL in structures

It is necessary to say a few more words about the classification of the material, depending on the features of its application in a particular frame structure.

  • "Wall" - when installing partitions or finishing walls, slabs with a thickness of 12.5 mm are mainly used. Naturally, if a structure of increased strength is required, it is necessary to increase this parameter, which can always allow a variety of drywall sizes.
  • "Ceiling" - for sheathing the frame of a false ceiling, a material with a thickness of 9.5 mm is most often used, since the use of a thicker one will significantly increase the weight of the structure.
  • "Arched" - suitable for mounting structures that have a curved shape (arches, curly partitions, etc.). To the question of what size of sheet the drywall for arches has, we will answer - it does not matter, the main thing is that its thickness does not exceed 6.5 mm. Only this parameter gives good opportunities for creating elements of any curved shape.

Having told you about the features of drywall, I would like to add - what size drywall sheets have and the type to which it belongs - of course, important factors that must be taken into account at the stage of design work. However, the main feature of the GKL is that in the rooms finished with its help, there is a special atmosphere that is most favorable for human life.

We are waiting for your feedback and comments on the topic of repair work and interior decoration. You can always ask questions to our experienced specialists and get a qualified and competent answer.

Standard drywall sheet size

The use of drywall is not an innovation in the modern world, but recently more and more people have begun to use it in repair and construction work.

Today it is difficult to imagine a room where drywall would not be present.

What is this material?

Drywall was originally invented by the American Augustine Sackett in the 19th century, who owned an entire paper mill and once noticed that when making paper, layers are obtained, consisting of 10 layers of cardboard, and between them there is a small layer of gypsum, about 1.5 centimeters.

Subsequently, Augustine Sacket patented his invention and this was the beginning of the emergence of modern drywall.

But it marked the appearance of exactly the drywall that we use to this day, Clarence Utsman.

It consists of 6% cardboard, and the rest is gypsum dough and only 1% is given to starch and other impurities.

In fact, drywall is a building material, which is presented in the form of two layers of building cardboard and a layer of gypsum dough between them.

This is a relatively new type of building material (since it was used back in the late 50s of the 20th century), but it has been widely used in the last decade.

This was marked by the fact that the material is very convenient to use.

Firstly, due to the fact that it is a light and fairly environmentally friendly material, and secondly, because it is an absolutely non-combustible product, which helps to secure your home and, moreover, it is relatively inexpensive.

Drywall has a number of positive features, because it:

  • ecologicaly clean;
  • easy;
  • lasting;
  • it has a smooth texture;
  • has a reduced water absorption;
  • he has a pleasant appearance;
  • acceptable price for excellent quality;
  • has no smell.

Its use can be presented in various variations, for example, such as:

  1. Creation of false ceilings.
  2. Creating partitions.
  3. It is very convenient for hiding various small items: cords, wires, tubes and much more.
  4. Alignment of walls and ceilings.
  5. Creation of any design.
  6. Implementation of ventilation tasks.
  7. The basis for pasting wallpaper and much more.

The geometric dimensions of the GKL Knauf

Knauf drywall has a rectangular shape and consists of several layers of cardboard, between which there is a certain layer of gypsum dough, which contains various additives.

This type of material is produced exclusively according to German standards and is one of the highest quality on the market today.

It is characterized by high strength and reliability, which, in turn, cannot but please even the most demanding customers.

It is perfectly used for embedding walls, constructing suspended ceilings and any other structures in the room.

Each Knauf drywall sheet has its own special designation, which consists of the following indicators:

  1. The presence of numbers that indicate the size of the sheet.
  2. Letter symbols indicating the type of GKL.
  3. Symbols that indicate the Knauf group.
  4. Values ​​indicating the types of longitudinal edges of the GKL.
  5. Symbols indicating the material standard.

As an example of such a designation, drywall can be given, which has a length of 2500 millimeters, a width of 1200 mm, and a thickness of 12.5 mm: GKL-A-UK-2500x1200x12.5 GOST 6266.

Knauf drywall can have different sizes depending on its purpose.

So, for example, the length of one sheet can vary from 2000 to 4000 millimeters in increments of 50 mm, the width can be from 600 to 1200 millimeters, and the thickness of the GCR is presented in a wide variety: 6.5; 8; 9.5; 12.5; fourteen; 16; eighteen; twenty; 24 mm.

Additionally, small sheets of drywall with dimensions of 600x1500 mm are produced.

There are no special sizes of sheets of material for the ceiling.

Therefore, drywall with standard dimensions is used as a ceiling.

Read more about the installation of suspended ceilings on our website.

You can find out about two-level plasterboard ceilings at the link. How to choose the design of two-level plasterboard ceilings and how to install them.

Read about suspended ceiling made of plastic panels here. What are the dimensions of the panels and how to sheathe the ceiling with them.

Only they try to choose the minimum thickness in order to reduce the mass of the structure and reduce the number of mounting profiles.

Drywall Knauf in its qualities and features can be attributed to certain groups, such as:

  1. G1, which means flammability according to GOST 30244.
  2. B2, which means flammability according to GOST 30402.
  3. D1, which, in turn, means the ability to smoke according to GOST 12.1.044.
  4. T1 - this designation refers to toxicity according to GOST 12.1.044.

As for the transportation or transportation of this type of drywall, you need to be extremely careful, because it is quite fragile, the slightest wrong movement can lead to damage to the newly acquired material.

It is necessary to install exhaust ventilation in the room, since Knauf drywall, although moisture resistant, can be deformed at a humidity of more than 70–80%.

Therefore, before using this material in equipping your premises, you need to familiarize yourself with the requirements and apply appropriate precautions.

Types of drywall sheets

At the moment, there are three main types of drywall: standard, moisture resistant and fire resistant.

They have their own abbreviations:

  1. GKL - stands for ordinary drywall sheet. It, in turn, is a universal material, as it is suitable for almost all rooms.
  2. GKLO is drywall, which has a fairly high fire resistance, which, in turn, is suitable for rooms with a high temperature or with a high probability of ignition. This type of material is also different in that it can withstand about 20 minutes of direct exposure to fire.
  3. GKLV is a plasterboard sheet, a feature of which is moisture resistance. Certain antifungal mixtures are added to it in order to make it as moisture resistant as possible.
  4. GKLVO is the last type of drywall. It can also be called a hybrid of moisture-resistant and fire-resistant gypsum board.

And now consider each type of drywall separately.

Standard

Standard drywall or drywall are ordinary sheets that are used in almost all rooms with a normal level of humidity.

It is a finishing sheet, which is most often used in false ceilings, partitions, wall cladding or the construction of various structures.

This type of material is in great demand because it is the most common, affordable and, most importantly, versatile.

GKL can be of various sizes, but the following values ​​\u200b\u200bare taken as the standard:

  1. Length - 2.7 meters.
  2. Width - 1.2 meters.
  3. Thickness - 9.5 millimeters.

The weight of one standard sheet can vary from 21 to 32 kilograms.

The length of the GKL can be from 2.5 meters to 3.3 meters, and the thickness of one sheet is from 9.5 to 12.5 millimeters.

As for the prices for this type of material, they can be considered quite democratic.

On average, in Moscow there are such prices:

  • with dimensions of 2000x1200x9.5, the price reaches 200–300 rubles per square meter;
  • with dimensions of 2500x1200x9.5, the price reaches 300-400 rubles per square meter.

moisture resistant

Moisture resistant drywall is a type of drywall sheets that are produced using a special technology.

Its lining is treated with special agents that prevent the appearance of fungus and mold.

Silicone is introduced directly into the GKL structure, which reduces the possibility of moisture absorption.

This type of building material is used mainly for cladding the external facades of houses, bathrooms, showers, kitchens and other rooms with high humidity, provided that good ventilation is provided and the front surface is protected with additional moisture-resistant materials, for example: paints, waterproofing, ceramic tiles.

It is also possible to use it to create partitions, various decorations and sound-absorbing products.

GKLV can be of various sizes.

The following parameters are considered standard:

  1. Length - 2.5 meters.
  2. Width - 1.2 meters.
  3. Thickness - 12.5 millimeters.

The weight of a sheet of such a GKLV can be within 32 kg.

But the dimensions may vary, for example: width - from 2.5 to 4 meters; thickness - from 9.5 to 15 millimeters, weight - from 9 to 15 kg per square meter.

In turn, the prices for this type of GKLV can also vary.

It depends primarily on the size of the sheet of material itself, on the manufacturer, on the store that supplies this product, and on a large number of other factors.

In this regard, prices can be as follows:

  • with dimensions of 2000x1200x12.5, the price is about 200-300 rubles per m2;
  • with dimensions of 2500x1200x12.5, the price will be about 300–400 rubles per m2;
  • at 3000x1200x12.5, the price reaches 300–400 rubles per m2.

fire retardant

Fire-resistant drywall is a rectangular building material with increased resistance to heat and open flame.

One sheet of such GKLO consists of several layers of special cardboard, between which there is gypsum dough with various reinforcing additives to strengthen the material itself.

The composition of the GKLO core includes additives that increase its refractoriness.

This type of drywall is used for facing various rooms with normal humidity, for creating fire-resistant structures, for finishing fireplaces and ceilings.

The standard dimensions for fireproof drywall sheets are basically as follows:

  • length - 2.5 meters;
  • width - 1.2 meters;
  • thickness - 12.5 millimeters.

Dimensions may vary.

So, the length ranges from 2000 to 4000 millimeters, the width can be in the range from 600 to 1200 millimeters, and the thickness is from 6.5 to 16 millimeters, depending on the amount of work performed.

Video about the thickness of the drywall sheet for the ceiling:

The cost of this type of GKL depends: on the material from which it is made; from the manufacturer supplying the goods to retail outlets; and from other factors.

Therefore, the approximate price of GKLO in Moscow ranges from 350-450 rubles per square meter.

Drywall - sheet size: length, width, thickness


drywall sheet

Currently, one of the most common finishing materials is, of course, drywall.

This is a versatile material, it is used for almost all types of finishing work, whether it is finishing ceilings or walls, bathrooms or kitchens.

Drywall has many advantages over other materials, here are some of them:

  • environmental friendliness - undoubtedly, this material is perhaps the most environmentally friendly, because it contains purely natural materials.
  • fire resistance - due to its structure, drywall is a non-combustible material.
  • lack of toxicity - due to the fact that the composition contains only natural components, respectively, there can be no talk of toxicity.
  • pH is the level of acidity, which is noteworthy, drywall has almost the same level as human skin, which means that when working with this material you will not need to use special skin protection methods.
  • economic component - the cost of drywall is low.
  • ease of installation - for laying this material does not require any special skills.

Varieties of drywall and their brief description

Gypsum boards ordinary (GKL)


Plain drywall

The cheapest and most commonly used types of drywall. It consists of a core represented by gypsum dough, and is covered on top with thick cardboard, which gives shape and strength to the sheets.

It is used more often in rooms without any special conditions, whether it be humidity or temperature changes. This type is laid both on the walls and on the ceiling.

Fire-resistant gypsum boards (GKLO)


Fire resistant drywall

Already from the name it follows that this drywall is used for interior decoration near various fireplaces and stoves.

It also consists of a gypsum core inside and hard cardboard outside, but already treated with a special material, which gives increased fire resistance.

Used for finishing ceilings and walls, perfect for laying tiles or decorative plaster.

Moisture resistant plasterboard sheets (GKLV)


Drywall moisture resistant

This type is most often used in rooms with a high level of moisture, such as a bathroom, toilet, kitchen.

Its peculiarity is that the composition contains, in addition to standard cardboard and gypsum dough, special additives that reduce the absorption of moisture, i.e. they are moisture resistant.

This means that the sheets do not delaminate and do not lose their shape. Also, these species are more resistant to various bacterial and fungal infections. Although in very damp rooms, we still recommend laying more ceramic tiles on top.

Moisture-resistant sheets are not 100% resistant to moisture, so if your neighbors flood you, it will most likely get wet. The material of a 100% moisture-resistant direction can only be a tile.

Fire and moisture resistant drywall

Fire and moisture resistant plasterboard sheets (GKLVO)

This species is the most protected from various influences.

It is ideal for all the above finishes, the only negative is the price, it exceeds all previously described types.

Dimensions of drywall sheets

Depending on the purpose, the sheets are divided into:

  • wall - its thickness is 12.5 mm, and already from the name it is clear that it is used for wall decoration.
  • ceiling - has a thickness of 9.5 mm, used for finishing the ceiling.
  • arched - thickness 6.5 mm, most often it is used to create unique arched compositions.

The most common drywall size is 2500-1200-12.5 mm, its weight will be approximately 29 kg. The area of ​​such a sheet is 3 square meters.

The table shows the most common species:

As can be seen from the table, the width of the sheets, regardless of the place of application, is always the same. Only thickness and length can be changed.

Most often, the dimensions of drywall are as follows:

  • 1200x2000 mm;
  • 1200x2500 mm;
  • 1200x3000 mm.

How to calculate the right amount of drywall


Room dimensions for measuring wall area

In order not to return the remnants of drywall in the future and not to go to the store several times for it if you do not have enough, you must first calculate exactly how much material you need.

And how to do it right, we will now explain to you. The main factor that should be deposited in your head is the least number of seams.

Therefore, if your room height is 230 cm, then you don’t need to buy 200 cm sheets and then add 30 cm from another sheet, it’s better to buy 250 cm and cut 20 cm from them, let it be more expensive, but more aesthetically pleasing and durable, plus saves you time during installation.

Therefore, in order to take what is needed, we will do the following. Let's take an ordinary sheet of paper and draw each wall, taking each square as a certain scale. Thus, in a different color, by selecting the desired sheet size, you can draw and see exactly how much drywall you need.

As a last resort, we do this, we calculate the area of ​​\u200b\u200bthe walls (ceiling), for this the width is multiplied by the length of the surface, then we add about 20% more and that's how much material we need.

What should be paid attention to when installing this material


Installation of plasterboard structures

There are several ways to mount this material, one of them is gluing. For this, a special construction adhesive, based on gypsum, is used.

This method is relevant only if the wall is flat, and during the installation of wall drywall there will be no large gaps between the sheets.

But this material is suitable even for uneven surfaces. It is very often used precisely for leveling those very uneven walls. To do this, you first need to fix the metal structure, which will serve as the basis for installation.

The frame is made of a metal profile, in extreme cases, of wooden slats, and their desired thickness should be 2-3 mm. The structure can be fixed either also with glue, or with dowels with screws, this option is more reliable. Next, you need to fix the drywall to the structure.

To do this, you need at least 2 people, or even 3, to hold it, because with excessive bending, the GKL sheets break easily. We will fix with screws using a screwdriver. Since it is the screws that are able to hold drywall with the highest quality.

Briefly about the main

  1. Drywall is the most common and environmentally friendly material, there are sheets that are moisture resistant and also able to withstand fire;
  2. Depending on the place of application, drywall can be - arched, ceiling and for walls. Therefore, before buying, it is worthwhile to find out for what purpose you need this material.
  3. By size, the most common sheets are:
    • 1200x2000 mm;
    • 1200x2500 mm;
    • 1200x3000 mm.

    Moreover, each of them can be of different thickness - 6.5 mm, 9 mm, 12.5 mm.

  4. It is best to fix drywall on a frame made of a metal profile, 2-3 mm thick, for fixing it is best to use screws or self-tapping screws.
