It’s rare that a redevelopment can be done without erecting new partitions, unless you decide to make a studio and are just tearing down the old walls. New walls can be erected from piece materials, such as bricks, slabs and blocks of various compositions - we have already talked about them in the article “”. Or use sheet materials. There are three most popular today, and we are ready to tell you about all their pros, cons and features so that you can choose the best one.
A plasterboard sheet is a layer of gypsum wrapped in thick paper, measuring 1200x2500x12.5 mm and weighing 29 kg. It can also be thinner - 9 mm wide, but this option is very fragile. It is mounted as follows: first, a frame is formed from a metal profile, then plasterboard sheets are sewn onto the frame in two layers, overlapping on all sides. The final wall thickness will depend on the width of the metal profile used 50/65/75/100 and will be 100/115/125/150 mm, respectively. GKL sheathes not only walls, but also ceilings.
Waterproof plasterboard sheets (GKLV) of green color are also sold, but they are conditionally waterproof: with constant exposure to water, such sheets will swell, even if they are covered with tiles on top. It is better not to use it at all in “wet” rooms.
GCR cost: 250-350 rub./piece. GKLV will be more expensive.
Pros:
Minuses:
GVL also consists mainly of gypsum, but is reinforced with various environmental additives. The assortment includes PC sheets - with a straight edge, they are intended for walls, and FC - an edge with a recess (for the floor). There is also a GVLV (waterproof gypsum fiber sheet) in stock: it does not differ in color in any way, it only has a seal indicating moisture resistance.
Dimensions of the gypsum fiber sheet are 2500 x 1200 x 10/12.5 mm, weight 36/42 kg. More often, a thickness of 10 mm is used for interior partitions. The metal frame is sheathed with GVL sheets in one layer, unlike gypsum plasterboard. To improve sound insulation, you can make two layers, but then it is better to combine: one layer of gypsum fiber board, the other of gypsum plasterboard.
Thickness of the final single-layer gypsum fiber board partition 10 mm: 70/85/95/120 mm depending on the width of the selected profile.
Price: 450-500 rub./piece. The final wall turns out to be approximately the same in cost for gypsum plasterboard and gypsum board, since gypsum plasterboard is mounted in two layers, and gypsum board in one.
Pros:
Minuses:
DSP is the golden mean between wood and stone in its properties. Made from cement, wood fibers and liquid glass (stationery glue). There are slabs for interior decoration and for façade (FCSP). Size of one slab: 2700 x 1250 mm or 3200 x 1250 mm, and thickness to choose from 8/10/12/16/20/24/36 mm. For interior partitions, widths of 10 and 12 mm are most often used; the weight of slabs of this width is 46 and 54 kg, respectively. It is better to choose the widest frame - metal or wood. The final width of the wall will be about 12 cm.
Price: 800-900 rub. per slab 2700 x 1250 x 10 mm.
Pros:
Without gypsum plasterboard (gypsum plasterboard sheets) in today's fast and mass construction there is nowhere. Since the second half of the 19th century, plasterboard analogues have encouraged designers and repairmen to take the path of “dry construction”. Since then, the material has undergone dozens of changes, but its essence has remained the same. It is indispensable in the construction of partitions, slopes and technical boxes; it is used in upholstery of ceilings and walls, and even designer curvilinear complexities are made using plasterboard.
Reliable and durable, gypsum board has defended its independence as a separate technology. A great variety of plasterboard systems are offered by gypsum plasterboard manufacturers; in this area there is a serious struggle for a place in the sun. These are mainly well-known transnational companies, less often domestic manufacturers; sometimes there are business sharks who manage to import gypsum boards from the Middle Kingdom. However, in order not to become completely confused about brands and manufacturers, and to avoid outright fraud, you should figure out how to choose drywall - a quality product, and not throw money away.
GCR has a simple design: it consists of a flat core based on a gypsum mixture, which is lined on both sides with a thin layer of cardboard. This design guarantees the necessary rigidity, and the different base of the core gives it special protective properties.
Drywall is divided into several types - it all depends on your needs.
Quality is a perennial problem. Transportation and storage from our drywall suppliers leaves much to be desired. In small stores, the material may be stored in damp rooms or placed outside under a canopy. Dents, scratches and curvature from multi-tiered storage pallets, careless work of loaders - do you need it? Even initially high-quality material will turn into a pumpkin after such tests at twelve o’clock at night. You don’t want to pay money for it and end up with a damp, paintable ceiling and a curved wall after installation.
Use the following simple tricks to avoid making the wrong choice:
1. Do you want to buy a product that is not the first freshness? Then avoid large distribution points and go straight to the market or to a dubious store, where a skillful businessman can sell you stale goods.
2. If the risk of buying damp, mechanically damaged or crooked material does not scare you, just listen to the seller. Better yet, trust your eyes and try to evaluate how the plasterboard is stored, and, in general, the neatness of the room and the decorum of the place where you take the drywall.
3. It's all in the details! Once you are sure that the store or supplier is worthy of attention, do not rush to hasty conclusions. Even famous manufacturers come across defective batches. Make sure of the quality of the products yourself. Externally, the drywall should not have any defects: no crooked bends, no damaged corners, no dents on the surfaces and no scratches. All this will lead to a break in the damaged area, and such a gypsum board will fly into the firebox. (Although, plaster does not burn...) The paper should not move away from the core or curl on the back side, and the edges of the edge should not be folded. Even a person with very poor vision will clearly notice a gypsum plaster with the above defects, and you even more so.
4. Surveillance of loading operations. If you come across the perfect gypsum board in a store, this does not mean at all that it will arrive to you as such. Be vigilant and pay attention to the care of the movers during loading and delivery, because it is your money. It is unlikely that the warranty will apply if the purchase and delivery went smoothly, and mechanical defects were discovered afterward. Moreover, during transportation they may mix it up and deliver you the wrong batch: the size and number of sheets is suitable, and that’s fine. And you will no longer feel good. Therefore, try to make sure that there is a manufacturer’s marking on each gypsum board, if any.
5. Hurry up, as they say. The customer’s zeal to buy everything at once does not lead to any good. If you have started large-scale construction, buy gypsum plasterboard “for testing” and cut your sample into strips. In this case, the core should be uniform in appearance, the cut should be smooth and without inclusions, and when cutting, the knife should move smoothly.
6. Excessive price. Decided to save money? You will regret this when, under the weight of the structure, the Chinese cardboard begins to bend and goes sea waves. As unconventional as it may sound, you need to choose a trusted manufacturer. Does it make sense to pay extra for a name? For the name - no, but for the quality of the famous manufacturer - yes. Moreover, if you find drywall cheaper, then the benefit, in the end, will not be too great, but the final quality will suffer. It is better to buy drywall from a well-known brand.
Drywall manufacturers offer a lot of options plasterboard systems, dry mixes, accessories and other building materials. Transnational giant companies are still in charge here; there are also quite a few Russian enterprises, less often these are non-European representatives. About 70% of gypsum board sales in Russia belong to a German company "Knauf", 10% comes from brands "Rigips", "Lafarge", "Giproc" and others, and, of course, a confident 20% of sales consistently go to domestic manufacturers.
The Knauf group has more than ten branded factories throughout Russia. The Polish Lafarge Group and the British company Gyproc also have their own production facilities in our country. Among our manufacturers we can name JSC Gips.
To prevent your eyes from running wild when choosing branded plasterboard, you need to note the following points about suppliers:
If you ask which drywall is best to choose, 8 out of 10 builders will answer you - “Knauf”. This is one of the most popular German plasterboard manufacturers, which has been afloat for 70 years and is a leader in the plasterboard marathon.
The Knauf group produces wall gypsum plasterboard with a thickness of 12.5 mm, ceiling gypsum plasterboard with a thickness of 9.5 mm, and arched gypsum plasterboard with a thickness of 6.5 mm for curved structures. It is most convenient to bend it both on special templates and directly in place on the frame. The standard size of gypsum boards is 2500x1200 mm with an area of three square meters. Non-standard variations range from 1500 to 4000 mm, widths range from 600 to 1500 mm, thickness varies from 6.5 to 24 mm. The weight of gypsum boards ranges from 12 to 35 kg.
The company's pricing policy is varied, there are budget options. However, all material is of German quality.
Scandinavian shark of the drywall business. Existing since the beginning of the 20th century, the company produces not only drywall, but also other building materials. In 2002, it began to take first place in terms of the volume of plasterboard products produced.
“Gyproc” is a “green” company, its products have official confirmation of safety - the “Leaf of Life” and “Ecomaterial” stamp. The company has also created a lightweight version of plasterboard, which is 20% lighter than products from other manufacturers. The length of gypsum boards is from 2.5 to 3.6 meters, depending on the type of edge, the width of the sheets is 1.2 m, less often 0.9 m. The standard thickness is 12.5 mm, but generally varies from 6.5 to 15.4 mm. Gyproc is more expensive, but not much more than Knauf products.
The Polish company Lafarge Group is a real long-liver in the plasterboard world. The production of plasterboard has been established almost everywhere to the globe, and even Knauf is inferior to it in terms of production volume. Lafarge also has the advantage of having an affordable price - its huge production capacity makes it possible to reduce the cost of products to increase competitiveness.
In 2004, a Polish company revolutionized the production of drywall when it began producing KGL with a semicircular chamfer, where all four edges were covered with cardboard film. Subsequently, this made it possible to create perfectly smooth surfaces. Four processed edges are the hallmark of Lafarge.
The products of this company are different a small amount sizes. Standard sizes sheets 1200x2500 mm and 1200x3000 mm, thickness 9.5 or 12.5 mm. Weight for gypsum boards is 7.1 and 9 kg, for KGLV - 9.4 kg.
This is a pioneer of Russian gypsum thought. The company produced the first Russian moisture-resistant plasterboard. The Volgograd plant has established the production of gypsum boards, focusing on European standards, and sells it at Russian budget prices. This plant produces Volma brand material, offering the buyer, in addition to the standard, moisture-resistant, fire-resistant and moisture-resistant plasterboard. The standard and constant sheet width is 1.2 m, the length remains within 2.5-3 m. The thickness of the gypsum board is 12.5 mm for wall cladding, although you can order 9.5 mm for ceiling cladding. Weight ranges from 8 to 12.5 kg
Drywall has established itself as a durable and strong finishing material, used for covering surfaces, constructing arches, partitions, and various curved decorative fragments. When choosing suitable plasterboard panels, their product range and optimal standard size are taken into account. Proper calculation of the second indicator allows you to minimize the amount of waste, that is, save a lot of money. Next, we will talk about what type of drywall is best to choose in a particular case, and what its ideal dimensions should be.
When choosing GC slabs, it is assumed that Finishing work will be conducted using the “dry” method. And the basis of the structures will be taken exactly from silica material. Other materials can be used as auxiliary materials for connecting, installing and finishing the base ones. The GC sheet has two components - a gypsum flat core and its frame in the form of durable cardboard.
Despite its small thickness, plasterboard for walls, arches and ceilings has a sufficient margin of safety. Such a popular material as wall plasterboard is very tough, and its internal gypsum content can be supplemented with various components to achieve certain qualities.
To correctly calculate the amount of material, you need to know the dimensions of the wall plasterboard. Having information about the range of types of material will help a lot here, because each type has distinctive dimensions.
According to the properties, wall or ceiling plasterboard is divided into the following types:
This type of panel has a standard structure in the form of a gypsum layer and thick cardboard on it. It is meant to be installed in rooms with normal humidity conditions. Thanks to its light weight and flexibility for cutting, working with gypsum board is extremely convenient.
The production of ordinary sheets is carried out in accordance with GOST 6266-97 according to the German quality standard. A thin rounded edge (PLUK) is used at the joints. The cardboard and gypsum contents are glued together using a special adhesive composition. Cardboard takes on the functions of a reinforcing frame and serves as a universal surface for subsequent finishing - painting, decorative plastering, wallpapering or tiling.
The manufacturer puts special marks on each sheet indicating:
For example, on standard sheet can be applied - GKL-A-PLUK-2700x1200x12.5 GOST 6266-97.
Fire-resistant gypsum boards are ideal for finishing non-residential utility areas and for constructing partitions. Due to their ability to resist ignition, they are used to cover surfaces located near heating devices (fireplaces, stoves).
A moisture-resistant variety of HA is created for improving rooms with high humidity conditions (kitchens, bathrooms, toilets). It contains additives that improve water repellency. Due to this, the material retains its shape and does not deform. This type of gypsum board has good resistance to the development of mold and fungi. For finishing a country house, this particular type of HA is preferable, since apartments in a private residential building always have higher moisture levels than rooms in a comfortable apartment.
This moisture-fire-resistant material combines two properties at once, which become clear from its name.
On specified types The gypsum board list doesn't end there. There are also types of panels that differ in the specific purpose.
For example, gypsum fiber board or gypsum fiber sheets. The composition of such boards is a gypsum base with the addition of cellulose fibers. Gypsum fiber is more durable and rigid compared to gypsum plasterboard. Such surfaces are not subject to the effects of fire; they are distinguished by a smooth surface.
Sheets based on gypsum fiber are used as a flooring base for tiles, for street finishing and construction work (frame structures of houses are assembled from them). Their installation is also permitted in rooms with a high degree of moisture formation. But for these purposes, special panels are chosen that are not susceptible to moisture - gvlv.
In addition to these types of drywall, manufacturers offer another type of material - sheets intended for repair. With their help, it is possible to correct individual small flaws in ready-made designs, formed during their operation.
There are also sheets available for sale that:
There is another classification of gypsum sheets, which is based on their purpose and the corresponding standard size:
The difference between arched panels is that they are easy to bend. And this is a good property that helps when creating arched and curved openings. Ceiling slabs are used to seal the ceiling part of rooms, giving them multi-tiered shapes. And wall plasterboard is used for the construction of partitions and wall coverings.
The standard length for drywall is considered to be 2, 2, 5 or 3 meters. However, some manufacturers are not limited to these limits and produce panels with a length of 1.5, 2, 7 or 3.6 meters. If necessary, some manufacturers, at the request of consumers, agree to immediately give the sheets non-typical sizes, for which they cut the material directly in the factory.
To cover the entire wall plane (under the ceiling), it is advisable to purchase sheets with a maximum length corresponding to the height of the walls. This creates fewer seams that will have to be sealed later. However, with a ceiling height of 2.7 meters, the use of three-meter panels is very inconvenient. Here difficulties arise with transporting the material and delivering it to the apartment. Because sometimes it's easier to choose Alternative option- several panels are not the same length.
The optimal width of the sheets is 1.2 meters. Why are frame racks mounted in increments of 0.4, 0.6 meters? Sheets of smaller format can also be found on sale today. Their width is only 0.6 meters, and their length is 2 (or 1.5) meters. Small-sized sheets are easier to transport by passenger transport. And their installation is also possible alone. However, it is recommended to limit their use to small surfaces. Otherwise, many seams will form. Flexible gypsum board can also have a narrow width (for example, a type of gypsum board called GKLD has a width of 1.2 m).
The standard thickness of drywall may vary. These are 6 (6.5), 9 (9.5) or 12.5 mm. Plates with improved characteristics in terms of strength and fire resistance can have a thickness of 15, 18 and even 25 mm.
To decorate the walls, plasterboard with a layer thickness of 12.5 mm is purchased. The use of “dry” repair technology became possible largely thanks to this type of building material.
For the construction of floating ceiling structures, choose ceiling slabs with a thickness of 9.5 mm. For suspended ceilings it is possible to use and wall slabs, however, the higher price of the latter and the heaviness of the created structure are not in favor of covering the ceiling with wall slabs.
Drywall with a minimum thickness (6 mm) is called arched. And for a reason. It lends itself well to rounding, which makes it possible to create semicircular and shaped elements from it.
The selection of the sizes of GC sheets proceeds after clarifying the required area of the room. With a wall height of 2.7 m, doubt often arises as to which length of sheets would be more appropriate - three meters with subsequent cutting on site or 2.5 meters with the addition of a piece of drywall of the missing length. In such a case, today it is possible to place an order with the manufacturer, immediately indicating right size sheets.
If this is not possible for any reason, then it is best to adhere to the principle of installing HA sheets, which provides for minimal formation of seams when joining panels. Beginners should take this into account when choosing the appropriate size of wall cladding.

If you don’t know the intricacies of construction skills, it’s difficult to figure out what thickness of plasterboard is best to choose for walls. The fact is that the dimensions of the slab, the thickness of the gypsum board sheet and the purpose of different types finishing materials are different. And it is important not to make the mistake of not using wall plasterboard for the ceiling or vice versa.
Drywall on the wall The use of gypsum plasterboard, like gypsum fiber board, for leveling wall surfaces has gained wide popularity, and for good reason.
After all, these materials have many advantages:
When choosing a material for leveling surfaces, it’s easy to get confused, because drywall is produced not only for finishing walls. And depending on the surface for which the gypsum plaster boards are intended, the dimensions and thickness of the sheet will also differ.

The thickness of the plasterboard for wall partitions determines the strength of the future structure. At the same time, taking into account that walls made of plasterboard sheets (GKL) are made both with laying slabs in one layer and in two layers, the optimal thickness of the material will vary depending on the type of structure chosen.
The first and most important parameter, which will be further influenced by the choice of gypsum board of one thickness or another, is, of course, the strength of the partition. Therefore, when deciding to purchase a certain type of sheet, always analyze what loads the future wall will have to be designed for. If it is a partition somewhere in an area of active regular movement, for example in a corridor or in an area doorway, then you should choose a more durable design.
Be sure to consider what type of partition will be organized. Among the standard plasterboard structures There are single-layer and two-layer partitions or cladding systems, as well as cladding with direct attachment to the base wall (see diagram No. 1).
Obviously, a gypsum board sheet that fits tightly to the wall, even if it is a little thinner, will be a fairly strong base. If we're talking about about a single-layer partition or cladding system, then you should think twice before choosing a plasterboard board with a thinner material thickness.
Another important factor on which the thickness of drywall to choose depends on the professional experience of the craftsmen performing installation work for installing partitions or cladding. The fact is that for sheets with a standard thickness, standards are provided for the distance between the placement points of the metal frame profiles on which the plasterboard sheets are supported.
If these standards are not observed, the quality of the material of the racks and frame guides is poor, as well as deviations from the optimal installation technology, thinner gypsum board sheets will not be the best choice for installation in an already unreliable structure.
As can be seen in the diagrams, the profile installation pitch is 600 mm or 60 cm. Here the most upper layer- this is the wall material, just below is a layer of dry plaster, then an empty space and wavy lines indicate the space for laying communications. The last bottom layer is gypsum board slabs of standard thickness. If preference is given to slightly thinner gypsum boards, then this step will need to be reduced to 30-40 cm.
As mentioned earlier, all standards when calculating plasterboard partitions refer to the generally accepted recommended sheet thickness. So, standard thickness plasterboard for walls is 12.5 mm. Alternatively, slightly thinner slabs are also used - 9.5 mm. When discussing various options regarding the choice of thickness of plasterboard walls or cladding, it is appropriate to talk only about these two numbers - 12.5 mm and 9.5 mm.
Plasterboard-based slabs are also made with several other thicknesses, but the vast majority of the material used in finishing the ceiling and walls has one of the two thicknesses indicated. In the table below you can see the dependence of weight plasterboard sheet on its thickness and other dimensional indicators. In general, the mass parameter is calculated based on the area of the slab, since they come in different sizes.
Based on the data indicated in the table, you can calculate the weight of the slab based on known dimensions, as well as find out the total weight of the gypsum plasterboard material required to finish a surface of a certain area.
It was mentioned earlier that professionals recommend using 12.5 mm sheets for wall decoration. However, if you are planning a more reinforced structure, you can make a two-layer partition or cladding using an interlayer of two 9.5 mm slabs.
Also, for a 9.5 mm thick plasterboard wall there is an important limitation - lamps, air conditioners, heaters or furniture weighing more than 2.5 kg cannot be hung on it without special preparation of the frame for these devices.
12.5 mm gypsum boards require a standard spacing of frame profiles - 60 cm, a thinner 9.5 mm analogue requires the installation of metal racks at a distance of every 30-40 cm. Also Special attention pay attention to the quality of the metal from which the metal profile is made, as it should have increased strength when using thinner plates.
When arranging the walls in the bathroom, only moisture-resistant gypsum boards with a thickness of 12.5 mm are suitable, followed by finishing them with tiles or painting them with protective paints and varnishes.

It’s rare that a redevelopment can be done without erecting new partitions, unless you decide to make a studio and are just tearing down the old walls. New walls can be built from piece materials, such as brick, slabs and blocks of various compositions - we have already talked about them in the article “From brick to glass blocks: what to build interior partitions from.” Or use sheet materials. There are three most popular today, and we are ready to tell you about all their pros, cons and features so that you can choose the best one.
A plasterboard sheet is a layer of gypsum wrapped in thick paper, measuring 1200x2500x12.5 mm and weighing 29 kg. It can also be thinner - 9 mm wide, but this option is very fragile. It is mounted as follows: first, a frame is formed from a metal profile, then plasterboard sheets are sewn onto the frame in two layers, overlapping on all sides. The final wall thickness will depend on the width of the metal profile used 50/65/75/100 and will be 100/115/125/150 mm, respectively. GKL sheathes not only walls, but also ceilings.
Waterproof plasterboard sheets (GKLV) of green color are also sold, but they are conditionally waterproof: with constant exposure to water, such sheets will swell, even if they are covered with tiles on top. It is better not to use it at all in “wet” rooms.
GCR cost: 250-350 rubles/piece. GKLV will be more expensive.
GVL also consists mainly of gypsum, but is reinforced with various environmental additives. The assortment includes PC sheets - with a straight edge, they are intended for walls, and FC - an edge with a recess (for the floor). There is also a GVLV (waterproof gypsum fiber sheet) in stock: it does not differ in color in any way, it only has a seal indicating moisture resistance.
Dimensions of the gypsum fiber sheet are 2500 x 1200 x 10/12.5 mm, weight 36/42 kg. More often, a thickness of 10 mm is used for interior partitions. The metal frame is sheathed with GVL sheets in one layer, unlike gypsum plasterboard. To improve sound insulation, you can make two layers, but then it is better to combine: one layer of gypsum fiber board, the other of gypsum plasterboard.
Thickness of the final single-layer gypsum fiber board partition 10 mm: 70/85/95/120 mm depending on the width of the selected profile.
Cost: 450-500 rub./piece. The final wall turns out to be approximately the same in cost for gypsum plasterboard and gypsum board, since gypsum plasterboard is mounted in two layers, and gypsum board in one.
This is modern construction material, which, due to its strength, lightness and ease of cutting, received wide application in covering walls, ceilings, as well as creating interior partitions and other architectural elements.
Now there are several types of this material, each of which differs in its properties, size and price. Which drywall to choose for finishing?
The type of edge is taken into account primarily when installing sheets. So, for sheets with a straight edge, a “dry” installation is used, others are used in combination with reinforcing tape or putty.
These parameters directly affect the transportability of the sheets: when purchasing them, you need to take into account the dimensions of the truck body and doorways in a buiding.
For finishing premises during renovation work, a material such as plasterboard, which is often called dry plaster, is widely used. Thanks to the fact that special mortar enclosed between special cardboard or paper, such material is very convenient for finishing premises. For wall finishing, plasterboard sheets with a thickness of 12.5 mm, the so-called gypsum plasterboard wall sheets, are most often used. But if you need to not only level the walls, but also make sound insulation, use gypsum plasterboards, so-called acoustic ones, which are slightly thicker and have a porous structure. They also take into account the room in which it will be used. For ordinary premises For finishing walls, traditional plasterboard with a regular thickness is suitable, but for the ceiling or for organizing arches and other structures, other types with greater or less thickness are needed.
Depending on the surface for which plasterboards are intended, they differ in markings, sizes and thickness. Traditional plasterboards, which are used for wall installation, are available in a thickness of 12.5 mm, and their sizes range from 60 cm to 1 m 20 cm in width, and their length varies from 2 meters to 4 meters.
But most often when finishing premises, sheet sizes from 2.5 meters to 3 m 30 cm long are used, and the width of a gypsum board sheet is 1 m 20 cm. Such sheets are convenient to transport and move around the room. They are not very heavy.
And working with such sheets is also quite simple. In some construction stores you can find sheet sizes in small formats, for example, such as 1 m 20 cm long and 60 cm wide. A finisher can even work with such boards alone, since their low weight allows this to be done.
If you couldn’t find such small sheet sizes, then it’s okay, you can large sheets Using a special knife, cut the plasterboard into required dimensions, which are convenient to work with.
In any case, the choice of sheet thickness depends on each specific conditions, room and volume of work performed. And also on the requirements for the room in which the plasterboards will be installed.
To decorate the walls in rooms, traditional plasterboard with a thickness of 12.5 mm is used, but if you plan to hang anything on the walls in the future, two slabs should be attached to the sheathing for greater strength.
If you need to finish a room that has special requirements, you must use different types plasterboard boards, for example:
After installation of such specific plasterboards, they must be treated accordingly. So, for example, when using moisture-resistant gypsum boards, their surface should be treated with moisture-resistant putties, paints and other finishing materials that have a certain resistance to moisture. The same applies to slabs that have a certain resistance to fire; they should also be treated with fire-resistant materials.
In addition to size, thickness and purpose, plasterboards are divided into two types: gypsum plasterboard and gypsum board. GKL are traditional gypsum boards consisting of thick cardboard or special paper and a gypsum layer. They are used in interior decoration. GVL sheets are made without shells, and their difference is that in gypsum mixture cellulose fibers added. This increases strength, and one of the surfaces of the sheet is already primed, which makes it easier to process this type of slab with finishing materials after installation.
Besides GVL sheets have increased strength compared to conventional gypsum board sheets, but at the same time they have a number of features:
Because this material much stronger, it is widely used in construction and in interior decoration, especially in those places where increased protection measures against shock loads are required. And also in those places where increased requirements are placed on the fire-technical condition of the premises. Due to the fact that this material successfully resists high temperatures, it is almost impossible to set it on fire. If you need to build any structure or do finishing in a room with high humidity, then gypsum fiber board sheets will be the best option. You just need to purchase GVL slabs treated with a water-repellent compound, which allows this material to more successfully resist moisture in the room. This material can also be successfully used for finishing unheated premises, since GVL slabs can withstand up to 15 – 20 freeze-thaw cycles.
What exactly is better than a GVL slab or a gypsum plasterboard slab cannot be said unequivocally, since both materials are good and are used successfully in finishing any premises, including those in which environmentally friendly use is important pure materials, which are gypsum plasterboards and gypsum boards.
