What to choose: gypsum fiber or gypsum board? Where is it used and how does gvl differ from gcl.

Today, a real construction boom is caused by two new materials - GKL and GVL. They are used in the now popular "dry" construction. Its essence is that the number of technological actions is reduced, including the need to dry the material. Accordingly, the entire workflow is much faster.

Many people mistakenly believe that GKL and GVL are practically the same materials. Yes, they have similarities, but they differ significantly from each other. To find out what the difference is, let's define each of them.

What is GKL and GVL

GKL are plasterboard sheets filled with gypsum inside, framed with cardboard on the outside (except for the end part). Gypsum is given additional strength by special components that connect the inner and outer layers of the gypsum board. Cardboard adheres well to gypsum thanks to additional adhesives. Plasterboard sheets are used to finish the ceiling and walls, they are also used to make interior partitions. Due to the fact that the outer layer of the plasterboard is cardboard, it is convenient to apply finishing materials on it.

GVL is a homogeneous and very durable sheet of gypsum fiber. Resistance to deformation is explained by the manufacturing technology: dry pressing turns GVL into the strongest material widely used in the construction industry. Dry screeds are made from it, and gypsum fiber is also suitable for work that requires the application of strong shock or mechanical impact to the material.

What is the difference between GKL and GVL

Both materials are in demand in construction, however, the purposes of using GKL and GVL differ. To understand which sheets to choose, you should familiarize yourself with their main characteristics in comparison. In terms of hardness, hypofibre is much better, while drywall is quite plastic, bends and cuts well, but it has very low fire resistance. But GVL burns poorly, but it is expensive. GKL is more affordable, and, perhaps, this is the main advantage of this material.

The initial difference between drywall and gypsum fiber lies in the method of production. GKL is made by pressing gypsum and gluing cardboard over it. GVL is obtained as follows: cellulose is made from shredded waste paper, which is mixed with gypsum and pressed. It is the initial uniformity of gypsum fiber that makes it stronger than drywall. The fire resistance of GVL plays an important role, this characteristic makes it attractive for industrial construction. GCR, on the other hand, is mostly used to level the unevenness of walls and ceilings with the possibility of their subsequent finishing.

So, it remains to sum up.

Construction practice shows that drywall sheets are more used for residential buildings, as they are relatively cheap and easy to bend and cut. Gypsum fiber sheets are more attractive for finishing production shops, as they are resistant to fires, but their cost is much more expensive.

Drywall has been the most popular sheet finishing material in our country for over 10 years.

Plasterboard sheets (GKL) and gypsum fiber sheets (GVL) are ideal for fast leveling walls and ceilings in a house or apartment with your own hands. But most novice masters do not fully understand the difference between them. I will talk about the pros and cons of each material so that you can understand the topic in detail and choose the best solution for your home.

Gypsum-fiber sheets differ from gypsum boards not only in appearance, but also according to the characteristics

Material characteristics

To understand how GVL differs from drywall, we will first consider each material separately, and then compare their performance. So you can clearly see what is the difference between each of the options, and you can decide what is best suited for a particular room.

Drywall

The material consists of gypsum, and the outer surfaces are covered with special cardboard, which provides additional strength to the sheets and makes the surface smooth. This simplifies the subsequent finishing.

Cardboard trimmed the entire sheet except for the top and bottom end

Advantages of drywall:

Illustration	Description
	Environmental friendliness. The composition of the material includes natural gypsum and cardboard. This allows you to use it in rooms of any purpose. In the process of work, it is not necessary to use protective equipment.
	Convenient options. The width of the sheets is most often 1200 mm; for complex structures, options are available for 600 mm. Height - 2500 or 3000 mm, but there may be other options. For walls, elements with a thickness of 12.5 mm are used, for ceilings and arches - 9.5 mm. The weight of the wall sheet is about 30 kg, and the ceiling sheet is about 23 kg. On the front side there is always an edge along the longitudinal end, so that it is easier to close and strengthen the joints.
	Ease of processing. The instruction for cutting the material and its fastening is very simple and does not require the use of special equipment and tools. Drywall is easily cut with a construction knife, and fastening is done using self-tapping screws.
	Flexibility. If you cut the inner layer of cardboard and moisten the material, then it can be bent. After drying, drywall again acquires strength. The photo shows how much you can bend the elements if necessary.
	Different variants products for different purposes. The material can be of three types: Standard. GKL is marked and used for general purpose premises; Moisture resistant. It has a green color, is marked with GKLV and is used in wet rooms; Fire resistant. It has pink color and is designated GKLO. This type is flame resistant.

Among the disadvantages of this option, low resistance to constant humidity and brittleness under shock loads can be noted.

When choosing the size of the sheets, consider the height of the ceilings. It is desirable that the entire wall be covered with one element, this increases the strength of drywall walls.

Gypsum fiber sheets

This option is made on the basis of gypsum and cellulose fiber filler, the surface is reinforced with two layers of fiberglass. This structure gives the sheets special strength and durability.

The gypsum fiber sheet is very durable due to the external reinforcement with fiberglass

The main advantages of this option:

• Environmental friendliness. Both GVL and drywall do not contain components harmful to human health. The material can be used in any premises;
• High strength. The material is well tolerated by all types of loads, including impacts. This allows you to use it both on walls and ceilings, and on the floor;

GVL sheets can also be used to level the floor

• Convenient sizes. The width of the elements is 1200 mm, there are small format options for 1000 mm and floor elements for 500 and 600 mm. The height is from 2500 to 3000 mm, the floor slabs are smaller - 1200-1500 mm;

GVL floor elements are small in size for ease of installation

• Excellent performance. The material initially has a higher moisture resistance than drywall, so it is better suited for the bathroom and other wet areas. In addition, it has high heat and sound insulation performance.

The thickness can be 10 or 12 mm, the first option is used for ceilings, the second for walls

Among the shortcomings, it is worth highlighting the following aspects:

• Big weight. With the same dimensions of GKL and GVL, the second option will weigh one and a half times more;
• Rigidity. An important difference between GVL and GKL is that the material does not bend. Therefore, it can only be used on flat surfaces.

GVL can only be cut with a circular saw or other similar tool

When cutting GVL, a lot of dust is generated, so you need to work with goggles and a respirator.

Comparison of options by main aspects

To fully understand how GVL differs from GKL, we will present the basic information on these materials in the form of a table. It clearly shows the difference between the options under consideration.

Indicator	GKL	GVL
Price	The price is from 70 rubles per square meter.	Varies from 180 to 300 rubles per square
Strength	Low, brittle material, cracks on impact	High, sheets withstand high loads and impacts without problems.
Ease of installation	Very easy to cut and attach. Moreover, there are no differences in processing for elements of different thicknesses, all options are easy to cut.	The elements are difficult to cut and install due to the heavy weight and hardness of the material. This difference from drywall greatly reduces the popularity of GVL.
Insulating characteristics	Medium. Decrease with increasing humidity	High. Cellulose fibers perfectly dampen sound vibrations and have heat-retaining properties

Both drywall and GVL are most often attached to the frame. It can be wood or metal. Due to the large mass of gypsum fiber boards, the requirements for the supporting structure are higher for them, the craftsmen recommend taking a profile with a thickness of at least 0.5 mm. Any elements are suitable for drywall.

The frame for GVL should be much stronger than for drywall

Output

After reading the review, you must decide whether GVL or GKL will be used for finishing. Weigh all the advantages and disadvantages of each option and only then make a decision. The video in this article will help you understand the topic even better, and if you have any questions, ask in the comments.

Gypsum fiber and drywall: what is the difference

Currently, the so-called dry construction methods are very popular. What explains such popularity? The answer to this question is easy to find. Indeed, with the help of this method, it is possible to reduce construction time and reduce the number of technical operations. From here it follows that the most popular material is gypsum fiber sheet and drywall. Therefore, today, together with the Beton-Area.com portal, we will find out how gypsum fiber differs from drywall.

What are these materials

So, first we need to say that drywall sheet It has natural gypsum as a basis, which is pasted over on both sides with thin cardboard.

Gypsum fiber has the same gypsum as its basis. However, there are some differences here. The "core" of such a material consists of gypsum, to which paper fractions or cellulose fibers were added during production. Thanks to these components, GVL is a material that has additional reinforcement. The gypsum fiber sheet does not have a cardboard shell.

Features of these finishing materials

Gypsum fiber and drywall are two different finishing materials. So now we will find out what the difference is.

First you need to understand what features the GKL has.

• So, drywall sheet is deprived of good strength. Therefore, during installation, a rigid profile crate is used. Before sticking a rigid crate on the wall surface, it is well leveled. Do this in order to avoid damage to the GCR.
• Drywall under the influence of moisture easily changes its shape. Therefore, such material is used to mount any curly structures.
• Attach the sheets to the wall with glue or self-tapping screws. Nails are not used in this case. Indeed, in this way, it is possible to damage the sheet of material.
• The material is easy to process. And to cut a sheet of drywall you need to use a sharp blade.

Now it is worth bringing all the features of GVL.

Gypsum fiber has the following technical characteristics:

• So, GVL is a strong and rigid material.
• Gypsum fiber has a high density and significant weight. It follows that such a material perfectly tolerates various thermal effects.
• Gypsum fiber does not have good flexibility. This quality makes cutting the material a difficult process. It follows that GVL is not suitable for creating arches and other complex structures.
• GVL exhibits good resistance to low temperatures. Here, this figure is much higher than that of a drywall sheet.
• Nails can be hammered into gypsum-fiber sheets, which will hold in this material no worse than in wood.
• Gypsum fiber is not able to absorb moisture. GCR here exhibits completely different characteristics. It follows that GVL is suitable for finishing the bathroom.
• GVL is also characterized by a good indicator of sound insulation. Indeed, this material has a much better sound insulation index than drywall.

Scope of GVL

Now you have learned how gypsum fiber differs from drywall. Now I need to say about the scope of the gypsum sheet. So, such material for interior decoration is produced in the form of rectangular sheets, which can have different sizes. However, the most popular material is considered to be a gypsum-fiber sheet with dimensions: 10-12 mm in thickness, 2500 mm in length and 1200 mm in width.

Gypsum fiber is used for finishing and construction of residential buildings and utility rooms. Also, with the help of such material, you can arrange a high-quality flooring. In this case, GVL is used here as a basis.

Pay attention to the article: Gypsum tiles under a stone for interior decoration: photo and technical characteristics of the material

Moreover, gypsum fiber sheet can be used to build partitions between walls in residential areas. It has already been said above that such material can be an excellent finishing material for rooms with high humidity. Therefore, gypsum fiber is used for the base and for subsequent wall decoration with other materials in the bathroom and utility rooms with a high degree of humidity.

GVL has been widely used in industry. For example, gypsum-fiber sheets are used to equip rooms that have high requirements for fire safety.

01

Scope of GKL

Before talking about where this material is used, it must be said that drywall has several varieties. So, there is moisture-resistant drywall, drywall for wall cladding and ceiling drywall. With regard to the size of drywall, then basically consumers are buying up standard drywall sheets. Such sheets have the following dimensions: 1.2x2.5m.

GKL is used in various works. In particular, ceiling drywall is used to create modern multi-level ceiling structures. This type of material is used during the creation decorative elements in room.

Drywall for walls is used for leveling walls and for sheathing perfectly different surfaces. A variety of this drywall is characterized by high weight and good thickness.

Moisture-resistant drywall combines the characteristics of the two varieties described above.

conclusions

As you can see, two modern material for interior decoration of premises have their own special technical characteristics, which differ from each other. Therefore, when choosing a particular material, you need to take into account their qualities and know the scope of their application.

Gypsum fiber and drywall - what's the difference? Consider all features

Such products are quite often used in the field of construction and repair - for leveling surfaces, changing their configuration (relief), and partitioning. It doesn't make sense to list everything. The presence of the word "gypsum" in their names indicates that these materials are practically the same and are nothing more than analogues.

This often introduces some confusion, and it makes it difficult for a person who is not experienced in special terminology to choose the best option for a particular situation.

What are these types of products?

Drywall (GKL) - a sheet, the basis of which is pure gypsum (pressed), glued on both sides with thin cardboard. Hence the name.

Gypsum fiber (GVL) - the basis is the same, but there is a difference. The "core" consists of gypsum, to which small paper fractions (cellulose fibers) are added. Therefore, GVL is a material with additional reinforcement (reinforcement). And there is no “shell” made of cardboard.

It is this difference in production technology that caused differences in some properties of materials and determined the specifics of their application.

Product Features

GKL

• Drywall is characterized by insufficient mechanical strength (even brittleness), therefore, for its installation, a rigid profile crate is required. Before sticking to a solid base, it must be perfectly aligned, since even with slight mechanical stress, the sheet breaks easily.
• GKL is quite pliable if moistened with water. It is this feature of it that is used in cases where it is necessary to mount a figured structure, for example, of an arched type. Or round the corner of the room.
• Sheets are fixed either with glue or with self-tapping screws. But the nail will not stay in the GKL - it will only pierce it.
• Cutting is not difficult - a sharp blade is often enough.

GVL

• Gypsum fiber sheets are stronger, tougher than GKL.
• The density (and, consequently, the weight of GVL) is also higher. Hence, greater than that of drywall, resistance to thermal effects.
• Reinforcing fibers reduce the flexibility and pliability of the material. This complicates its cutting, and it is definitely not suitable for the manufacture of arches.
• Stability before sub-zero temperatures higher than that of GCR, approximately 3.5 times.
• Some "viscosity" of the structure leads to the fact that a nail hammered into a sheet holds in it no worse than in wood.
• Gypsum fiber does not absorb moisture as intensively as GCR. Therefore, these sheets can be used to decorate rooms such as toilets and bathrooms. But we must not forget that, nevertheless, GVL also has a certain limit of resistance to liquids.
• The sound insulation index exceeds the similar characteristic of drywall by 1.5 times.

Perhaps this is the fundamental difference between gypsum fiber and drywall. All their other parameters are almost identical - the temperature range of operation, hygiene, and so on.

On a note! Each type of product is produced in various "modifications", which have differences in certain characteristics. Before purchasing a product based on gypsum, all the features of a particular sample must be clarified additionally.

Price

Sheets of both materials are produced in various sizes, thicknesses, and varieties. Therefore, if we summarize all the data, it turns out that, on average, GVL is about 1.8 - 2.2 times more expensive than similar GKL. Perhaps this is partly due to the fact that the latter have found wider application in everyday life.

Gypsum-fiber sheets against GKL - how are they different and which is better?

oGipse.ru → Materials

The building material that will be discussed is known to many. Gypsum fiber sheet is a mixture of pressed gypsum and cellulose fibers. It is made by a dry method without the use of moisture. Has two layers, one of which is primed.

Characteristic

Very durable building material. Has a large mass. Its structure excludes deformation and stretching. There is no possibility to bend. Does not contain formaldehyde and resins. Environmentally friendly. Special purpose sheets are resistant to fire and moisture. It has high heat capacity and sound insulation. The price per square meter reaches 300 - 400 rubles.

Application area

Gypsum fiber sheet is widely used in the improvement of premises for various purposes. It is used as for suspended ceilings, and for supporting surfaces, and various enclosing structures. Physical properties allow you to use it in rooms with high humidity, insufficient heating, in rooms that require improved sound insulation. It can be used both in wall cladding, construction of partitions, installation of ceilings, and floor insulation.

When insulating the floor of a room using a gypsum-fiber sheet, it should be borne in mind that the basis on which it will be laid may be different. For example, either a wooden, or concrete, or expanded clay pillow. Gypsum fiber is laid on this basis. The next layer will be a “finishing” floor: tiles, parquet, laminate, linoleum. The role of the gypsum-fiber sheet in this design is to create a strong, fire-resistant, warm base.

The choice of this building material is so wide that it requires careful, individual approach taking into account the assessment of the room in which it will be applied. For example, there are sheets capable of absorbing and also retaining a certain amount of moisture, which gives grounds for guaranteed use in rooms with high humidity.

Features of GKL and differences with GVL

There is a building material that does not require advertising. Everyone who at least once undertook to do repairs with their own hands or turned to specialists is familiar with him. This material is called drywall. In terms of structure, it is a dense gypsum layer on which two cardboard layers are glued. In terms of composition, it is filled with 93% gypsum (inner layer), 6% cardboard (outer layer), 1% organic matter.

Distinctive characteristics

Environmentally friendly. The content of threatening substances is zero. Endowed with impeccable sound-absorbing characteristics. Fire resistant (GKLO). It has sufficient moisture capacity, allowing it to absorb moisture when it is in excess in the room and return it when it is lacking. The price for one square meter reaches 100 rubles.

Practical use

Drywall is used for the construction of partition walls, cladding and leveling walls, ceilings. This finishing material is easy to install. Its use allows you to create cosmetic cleanliness in the room, hiding the communications available in the room under it.

Drywall makes it possible to implement various building and finishing fantasies, for example, niches, arches, columns, built-in lighting. If there are flaws in the design of the room, irregularities, curved walls, corners, drywall construction makes it easy to eliminate these errors.

Its surface is very practical, which allows you to simply prepare for pasting it with wallpaper, painting, or replacing some part of the structure. Possible errors formed during the installation of drywall (chips, seams, holes) are easily repaired with a related material - gypsum putty.

Acquisition of gypsum fiber and plasterboard sheets

Experts advise to purchase gypsum fiber and drywall from well-known international Knauf dealers. In this case, the quality of products is practically guaranteed. After all, this international company is based, without exaggeration, on best principles business and managed to keep them even in our time, with the fiercest competition and the current global scale of activity. The company has earned undoubted success with its responsibility and hard work.

Benchmarking in Applications

Strength

Gypsum fiber sheet (GVL), in which gypsum is reinforced with cellulose fiber, is a fairly strong building material, which cannot be said about gypsum board (GCR). The compressive strength of the former is much higher, it is harder to process, but it is weak in bending and is not so suitable for the installation of curved structures. Drywall is fragile. It can be pricked during transportation, loading, subject to moisture. Its use is not recommended in wet areas, except for a specially designed moisture resistant look. This is one of the most important differences between GVL and GKL.

Environmental friendliness

GVL is more environmentally friendly compared to GKL. Its rigid structure eliminates the destruction of the sheet mass, while the gypsum board loses its declared strength over time due to gypsum turning into dust, and therefore, respiratory problems may occur.

moisture resistance

Gypsum fiber can be used indoors without restrictions high humidity, while it is undesirable to use drywall in such rooms. But this material also has sheets containing special additives, the so-called moisture-resistant plasterboard (GKLV). They can be successfully used in wet areas.

fire resistance

The physical properties of GVL exclude its ignition, while conventional drywall requires coating to achieve the same performance. special composition that does not allow the cardboard to burn. It has a special marking - fire-resistant gypsum plasterboard (GKLO).

Practicality

GVL is massive, durable and heat-intensive. It can be used for floor insulation as its basis. GKL does not possess such properties, it has, first of all, a sham and decorative purpose. It cannot be used for flooring. At the same time, the lack of plasticity in the first deprives him of the opportunity to transform the room.

Price component

Gypsum fiber sheet is much more expensive. The difference for 1 m² in price can be up to 200 - 300 rubles. But this is the price for quality.

Conclusion: what better GVL or GKL? As we certainly could see from the above comparative analysis, it is clearly worth giving preference to the second option. Drywall has been replaced by a new building material - gypsum fiber, which has significant construction advantages.

It remains to add that the construction market, developing, offers more and more new building materials. For example, a glass-magnesite sheet (SML), which has a number of advantages:

How to install a drywall partition

Plasterboard sheets (GKL, KNAUF sheets) are a gypsum core, all planes of which, except for the end edges, are lined with cardboard. To form the core, G-4 gypsum is used, which has exceptional physical and technical properties. To achieve the required indicators of density and strength, special components are added to it. Another important component of drywall is facing board. Adhesion to the gypsum core is provided through the use of adhesive additives. Cardboard plays the role of a reinforcing frame and is an excellent basis for applying any finishing material (plaster, wallpaper, paint, ceramic tiles and etc.). Due to its physical and hygienic properties, cardboard is ideal for living quarters. Knauf sheets are used for interior wall cladding, devices interior partitions, false ceilings.

GKL are divided into:

• ordinary (GKL)
• moisture resistant (GKLV)
• with increased resistance to open flame (GKLO)
• moisture resistant with increased resistance to open flame (GKLVO)

Drywall Feature

It is known that GKL, along with the existing listed characteristics, has another remarkable ability - the acquisition of plasticity in the wet state and the restoration of its original quality after drying, while maintaining the shape given to it. This greatly expands the design and architectural possibilities of gypsum plasterboard as a building material, through the possibility of forming almost any curved surface, whether it be a ceiling or a wall. In the manufacture of curvilinear forms, plasterboard sheets 600 mm wide are used. It should be taken into account that the minimum bending radius of a sheet with a thickness of 12.5 mm will be approximately 1000 mm, and with a decrease in the thickness of the GCR, the radius also decreases. So, for sheets with a thickness of 9 mm, the minimum bending radius is approximately 500 mm.

GVL (gypsum fiber sheet)

Gypsum-fiber sheets (GVL, KNAUF-superlists) are used for interior decoration, especially those where there are increased fire safety requirements. They are made of gypsum not lower than G-4, with loose cellulose waste paper as a filler. Gypsum-fiber sheets are a homogeneous environmentally friendly building material used for interior partitions, suspended ceilings and interior wall cladding in residential premises, industrial buildings, facilities social sphere and medical institutions, schools, kindergartens and sanatoriums. Produced by semi-dry pressing. GVL is used for the installation of partitions and wall claddings with increased requirements for protection against impact, for the installation of prefabricated bases (dry screeds) for floors under coatings or in the presence of increased requirements for the fire performance of the structures used.

GVL are divided into:

• ordinary (GVL)
• moisture resistant (GVLV) (GVLV, unlike GVL, is treated with a special hydrophobizing liquid, which increases the resistance of its surface to high humidity)
• moisture resistant small format (DIY)
• KNAUF-superpol (GVLV EP)

Differences between GVL and GKL. What is better to choose?

So, having considered GKL and GVL, we will dwell separately on the differences. What to choose anyway? GVL is used for the construction of partitions and wall claddings with increased requirements for impact protection, that is, it is harder than GKL. GVL more easily tolerates sawing in any direction, as it is homogeneous in composition. GKL is less durable and is cut across so as not to disturb the cardboard reinforcement (although in some cases it is allowed), but it is capable of acquiring plasticity when soaked, and restoring its original strength when dried. Drywall is the best base for wallpaper. They can be glued without any pre-treatment, the only thing to do is cover the nail heads with nitro enamel or alcohol varnish to prevent corrosion. And you can not paste over the walls, but, for example, whitewash or paint with glue or oil paint, like ordinary plastered surfaces. It is not recommended to use only lime paints, as they do not adhere well to cardboard. It is impossible to answer unequivocally that it is better than GVL or GKL. There is no universal answer. It all depends on the task and the operating conditions of the premises.

The main grades of the profile for GKL or GVL

Metal profiles are used in all categories of buildings: residential, public, industrial and agricultural. They serve to form frames of various designs and purposes, including for partitions, claddings and suspended ceilings. Frames, in turn, are a rigid base for fixing drywall and GVL.

The main grades of the profile for fastening GKL or GVL:

How to cut sheets of drywall

When installing drywall, use solid sheets wherever possible. Cut the drywall sheet to length so that the end of the sheet rests on support beams, rungs, studs, or jambs. In order to properly cut the sheet to length, first install it so that the end of it protrudes beyond the edge to which you plan to lay the drywall. Measure the required length with a tape measure. Then use a special tool for drywall - a T-square and mark with a knife on a sheet of drywall the place where the cut begins and ends. Use a special knife to make an incision along the length of the drywall sheet. To get the most even line during the first cut, you can also attach an impromptu ruler to the drywall. For these purposes, you can use a wide metal profile, level, etc. Tap on one side of the sheet. Drywall should break exactly where you made the incision. If the end edge resulting from cutting is not smooth enough, then it should be corrected with a special grater. Peeling of paper from plaster should not be allowed. this may adversely affect the quality. If a paper “fringe” has formed at the end, it should be cut off with a knife. You can also use a drywall cutter to cut. This will not tear the paper covering the drywall core from below. Therefore, in order to completely separate the pieces of the sheet, run the blade of a knife over the cut to separate the back cover as well. A different drywall installation technology is used when you need to cut a sheet of drywall in places where there are internal corners. To make such cuts, use a special tool - a drywall knife. Make an incision in the place where you want to cut the sheet and sharply bend one edge back, as described above. After that, you will again have to cut the paper covering the drywall core from the back. Another way to cut for inner corner- first fix the sheet of drywall in the place where you make the overlap, and then with a knife - a drywall tool, make the desired hole.

Cutting figured parts from drywall

To get a part with uneven edges (arc, wave, zigzag, etc.), you can use a special file to work with drywall, but when using it, the sheet may crumble and the edge of the part will turn out to be uneven. If you try to align the edge, the dimensions of the part may change. In such cases, it is much easier and more convenient to use a jigsaw to work with drywall.

Drywall drilling

Often for mounting recessed lighting fixtures, etc. drywall holes required. Small holes are drilled with conventional drills, and larger holes (for halogen lamps, various pipes, etc.) are drilled with special files for drywall work or drilled with crowns.

Bending drywall

To create arches figured ceilings and some other designs, you need to get curved parts. There are several ways to work with drywall to bend a part.

First way. Wet the part and, when it becomes flexible, give it the desired shape. After drying, the part can be mounted. This method of working with drywall, of course, makes it possible to obtain a curved part, but it will require a significant investment of time, which will not please customers very much.

The second way. Use a special roller with spikes (spiked roller). It pierces paper with outside the intended bending of the drywall, and then the part is bent by applying physical force. As a result, the paper is torn due to punctures and makes it possible to bend the part. The method is quite effective, but it will require special skills, and the part can be difficult to screw on, and before puttying it will look completely unaesthetic.

Third way working with drywall to bend a part consists in cutting the outer side of the intended bend with an interval of about 5 cm. Depending on the steepness of the bend, the interval may vary. Then the part is broken in places of cuts, and bent to the required degree. The part prepared in this way is easy to mount, and it will take a minimum amount of time to manufacture it.

Drywall installation

First of all, it should be noted that in the world there are many systems and methods for installing drywall. Consider the most popular of them:

First way. Installation is carried out using the so-called adhesive compositions. This, one might say, is the easiest installation method: on a previously prepared (cleaned of old wallpaper, plaster, etc. and properly primed) wall surface (mounting plasterboard ceilings in this way according to natural causes not carried out) an adhesive composition prepared in accordance with the manufacturer's instructions is applied. The glue should be applied in “cakes” at a distance of no more than 35 cm from each other, with the exception of the corners of the room, and the joints of the sheets, where the glue is applied in a continuous layer. Also, when applying glue, one should take into account the individual slope, curvature, deformation of the wall, i.e. in convex places should be applied less glue, and vice versa. In places where the depressions are too large, you should first stick a strip of drywall, as if leveling the surface. You can check these characteristics with a level, and a thread stretched along the wall. After applying the adhesive, a pre-cut sheet of drywall is pressed against the wall. Further, with the help of a level and skillful hands, the sheet is set in the plane we need. Sometimes, when installing drywall on an adhesive, first drywall strips (the so-called “beacons”) about 15 cm wide are glued onto the wall, and the sheet itself is glued directly onto them. In this case, do not forget to let the glue dry. The advantages of this method are simplicity, high speed installation and no need for a special tool kit. The disadvantages include the impossibility of creating new partitions and niches: in addition, this method does not allow laying sheets on a wooden base.

The second way. Installation of drywall is made on a frame of wooden bars. The installation of drywall on a frame made of bars was popular about ten years ago, due to the shortage of metal profiles that existed at that time. This method consists of two stages: the assembly of the frame from the bars and the actual installation of drywall sheets on the wooden frame. The assembly of the frame from the bars begins with the exposure and subsequent fixation of the guides. Depending on the material to which the beam is attached, an appropriate fastener is selected, most often it is a dowel nail (if the base is concrete, brick, etc.) or a self-tapping screw with a large pitch (if the base is wooden). To set the guides, as well as the entire frame, a level and strips of veneer are used, which, if necessary, are placed under the bars. After installing the guides, the main bars are exposed and fixed. They should be installed no more than sixty centimeters apart, i.e. so that each sheet of drywall is attached at least at the edges and in the center, and the edges of adjacent sheets are attached to one bar. Before installing pre-cut drywall sheets, make sure that the assembled frame forms one plane, and, if there are any shortcomings, eliminate them. Drywall attached to wooden frame using wood screws. In this case, the distance between the self-tapping screws should not exceed thirty centimeters, and the self-tapping screws themselves should be screwed into the drywall in such a way that their caps are slightly recessed, but avoiding tearing the paper. Compared to the previous drywall installation method this way has a number of significant advantages. These, first of all, include the possibility of creating new structures, such as arches, partitions, niches, etc.; in addition, we get the opportunity to change the shape of existing walls and partitions. However, this is a more time-consuming and requires a special tool method. It should also not be forgotten that with changes in temperature and humidity, wood tends to deform, which cannot but affect the quality of the entire structure.

The third way. Installation of drywall using a metal frame. To create a frame, a metal profile is used. The assembly of the metal frame, as in the previous case, begins with the exposure and subsequent fixation of the guides. To set the guides, as well as the entire frame, a level is used. The difference lies in the fact that the main profile is fixed by means of special fittings, called "suspension", and self-tapping screws for metal. The use of suspensions allows you to simultaneously attach the metal profile to the wall and set it in the desired plane, which greatly facilitates the process of installing drywall. Suspensions should be located at a distance of no more than seventy centimeters from each other, and the main profile should be installed no more than sixty centimeters from each other, i.e. so that each sheet of drywall is attached at least at the edges and in the center, and the edges of adjacent sheets are attached to the same profile. Drywall is attached to the metal frame with metal screws. In this case, the distance between the screws should not exceed thirty centimeters. Installation of drywall on a metal frame is the most actual way today, because he, while retaining almost all the advantages of other methods, is not burdened by their shortcomings. In addition to all the advantages when using a metal frame, it is also possible to hide electrical wiring, heating radiators, pipes, etc. under drywall, and install built-in lighting– halogen lamps, etc. The disadvantages of this method include the need for a special tool and qualified specialists.

Security measures

Gypsum dust can cause irritation to the eyes and respiratory tract. Therefore, you should take care of protecting your eyes and lungs in advance. To do this, it is necessary to use goggles and a mask or respirator, as well as ensure proper ventilation of the repair site. Carefully study the purpose of each tool and use these tools only for the operations for which they are specifically designed. Unsharpened tools are dangerous and can interfere with or even harm your work. Always work with sharp blades. Keep an eye on your drywall tools and keep them in safe places. Always turn off the electricity in the room if you are working in a potentially fire-prone area. Be careful when working on goats scaffolding and stairs. We must not forget that when installing a building ladder, all of its legs must stand firmly on the ground. Never try to reach somewhere to the side or up while working on the stairs. Keep children out of the construction site and keep them away from power tools and building materials, solvents, etc., which may be hazardous to their health. Keep the work area clean and prevent debris and waste from accumulating on the construction site.

Last time on the market construction technologies more and more attention is paid to the so-called "dry" construction methods. This significantly reduces the time of work, reducing the number of technological operations and eliminating the need for drying the material. GKL and GVL can be noted among the most common materials currently used in construction. Many have heard of them, but few know how they differ. And the difference is significant.

Definition

GKL is a gypsum plasterboard, having in its composition a core made of gypsum. At the same time, all its edges, except for the end part, are lined with cardboard. From these main components the name of the material is formed. To give the material sufficient strength, binders are added to the gypsum used. The cardboard itself, which is good foundation for subsequent application of any finishing materials, has good adhesion to gypsum thanks to special adhesive additives. Drywall is used for processing walls and ceilings, as well as for the manufacture of interior partitions.

Gypsum board

GVL- gypsum fiber sheet, which is a homogeneous material used in construction. Its main feature is the high strength of the material. This is due to the technology of its production. The dry pressing method used for this makes it possible to obtain a very strong structure, which led to the widespread use of GVL in the construction of structures subjected to shock and other mechanical influences during operation. The material is in great demand in the manufacture of dry screeds.

Comparison

As you can see, both materials under consideration are of great interest. It is very difficult sometimes even for professionals to choose which one is preferable. Everything will depend on specific task that the material will be called upon to perform. Some distinctive features can be tabulated.

The main differences between drywall and gypsum fiber lie in the technology of their production. If a drywall sheet is obtained by pressing gypsum with gluing cardboard, then in the case of gypsum fiber, everything happens a little differently: in this case, gypsum is reinforced with cellulose, which is obtained by grinding waste paper. This shredded waste paper is pre-mixed with gypsum, which has special additives, and then pressed.

The result of this process is the increased strength of GVL, unlike GKL, as well as increased fire-resistant properties, which is highly valued both in civil and industrial construction. As for drywall, it is of particular interest for leveling walls before the subsequent application of finishing materials. The material is smoother and does not require additional processing.

Findings site

1. GKL is a very popular material, as it is easily cut and bent, which is especially appreciated when decorating suspended ceilings and other design elements;
2. GVL has a high fire resistance, which allows it to be widely used in production shops;
3. GVL is a more durable material that is used for the installation of partitions;
4. Drywall is a cheaper material.
