What can you cook from squid: quick and tasty

The abbreviation GVL means gypsum fiber sheet. GVL panels are an alternative to the popular drywall sheets (GKL). From a technical point of view, the gypsum fiber sheet is homogeneous building material, which is obtained using the method of semi-dry pressing from a mixture of fluffed waste paper with a gypsum binder solution.

What is the difference between GVL and GKL?

The difference between gypsum fiber and gypsum board lies in the fact that the first material is more homogeneous in structure, and cellulose fibers, introduced into the composition of the gypsum mass during the factory production of gypsum fiber, give it rigidity.

If you look at the cut of the gypsum fiber sheet, you can clearly see the reinforcing cellulose fibers. For comparison: in gypsum plasterboard, the reinforcing function is performed by cardboard layers (and not cellulose fibers), which cover the gypsum base on both sides. Often, GVL panels are additionally reinforced, which increases their mechanical strength.

Advantages of GVL in comparison with GCR

The above-described reinforcing structure of gypsum fiber sheets provides them with a number of advantages over gypsum board. Here are some of them:

• increased mechanical strength;
• minimal loss of strength during cutting in any direction;
• the best soundproofing;
• increased fire resistance.

By the way, the margin of safety of gypsum fiber sheets allows them to be used as flooring for subfloors.

Disadvantages of GVL in comparison with GCR

Unfortunately, GVL, like other building and finishing materials, has its own objective disadvantages compared to GKL. Here they are:

• minimum moisture resistance - when dry, strength is not restored;
• noticeably reduced bending strength, which makes it impossible to use GVL in the manufacture of curved structures;
• obligatory necessity preprocessing finishing sheet;
• higher price compared to the prices for gypsum board with the same dimensions (about 1.5 times more expensive); when purchasing large volumes of GVL, the rise in price will be noticeable.

Purpose of GVL

Based on the disadvantages of gypsum fiber sheets, an unambiguous conclusion can be made: this construction and finishing material should be used only where it is necessary to protect the wall (partition) from shock and damage, as well as where it is necessary to provide a zone of increased sound insulation.

The method of erecting a frame structure in 3 steps

Step # 1. Partition frame fabrication

The frame of the partition (or false walls) with its further plating of GVL is more expedient to be made from a metal profile. The work is carried out according to the following algorithm.

1. The layout of the room. Through appropriate measuring instruments lines are applied to the walls, floor and ceiling, along which the frame of the future false wall will be installed.
2. Installation of the starting profile. The starting profile is attached around the perimeter, securely fixed with anchors with metal or plastic sleeves. Anchors are screwed into holes with a depth of 4 cm. A sealing tape (anti-vibration rubber bands) is glued to the base of the starting profile in the places of its contact with the supporting structures (ceiling, floor).
3. Opening formation. Vertical posts are installed from the side of the doorway. The edges of this opening are made of elements, which, in turn, are assembled from a pair of rack-mount profiles, nested into each other. Then, from the rack-mount profile, the opening jumper is made, which is cut and bent into the shape of the letter "p", only inverted.
4. The final stage in the manufacture of the partition frame is the installation of vertical uprights. As soon as the opening is mounted, the vertical posts are installed. They are inserted both from above and below into the starting profile, fixing with self-tapping screws. The pitch of these racks should be selected in such a way that the edges of the gypsum fiber sheet during the sheathing process fall strictly to the middle of the guide.

It is worth noting that during the installation of the starting frame of the partitions, it is necessary to think in advance and provide for the laying of communications (if any) inside the false wall. For this, holes are made in the mounted racks for cable channels with electrical wiring.

Step # 2. Sheathing the frame with panels

So, as soon as the starting frame of the false wall is ready, it should be sheathed with GVL panels. This is done by cutting the sheet with a knife along a ruler. It is possible in other ways, but this method is the simplest and most popular.

1. The gypsum fiber sheet is trimmed to size, but care must be taken to maintain a gap of at least 6-7 mm between adjacent sheets during joining. This is to prevent deformation of the material.
2. Once the sheet is cut to size, it is applied to the frame and aligned. If the top edge "hangs" in the air, add another jumper to the structure.
3. The next stage is fixing the gypsum fiber board on the frame using self-tapping screws designed for gypsum fiber. For reference: for standard plates with a thickness of 12.5 mm, self-tapping screws 4 cm long are used. The screws are screwed in in increments of 30-40 cm. At the joints of gypsum fiber sheets, the screws are staggered - do not forget about this.
4. First, one side of the false wall is sheathed, then heat and sound insulation in the form of stone wool can be put inside the frame, after which the GVL partition can be sheathed on the other side. It is not recommended to leave the space inside the frame empty, since in the future the finished partition, upon contact with it, will emit an empty rumbling sound, accompanied by an echo and not pleasing to the ear.

Step # 3. Preparation for final finishing

Walls made of gypsum plasterboard are not walls made of gypsum plasterboard, so their finishing requires careful surface preparation. The structure of gypsum plasterboard is such that a porous gypsum board can provoke inhomogeneous polymerization of paint and adhesive composition. In general, in order for everything to work out as it should, it is better to act according to the following scheme.

1. Joining (grouting). If the trimming of gypsum fiber sheets was not accompanied by chamfering, all existing seams are embroidered.
2. Strengthening the seams. After grouting (joining), the seams should be treated with a primer, and then glued with a serpyanka.
3. Primer and putty. The surface is treated with primer for GVL. As soon as the primer dries, the structure should be putty: first, the fasteners and joints of the panels are processed to mask the caps of the screws, then the material is polymerized. Only after that the entire surface of the gypsum fiber is covered with a thin layer of putty.
4. Grinding. The dried putty mass is sanded with a float with an abrasive mesh. In the process, a lot of dust is generated, this should also be removed. Everything. The false wall is ready for finishing. Now you can make the finishing, i.e. pasting wallpaper.

Decorating rooms with gypsum fiber sheets has many advantages, due to the excellent characteristics of the material. GVL boards for walls have a number of parameters that distinguish them from similar types of products. Installation of products can be carried out in several ways and is not difficult, but it has some nuances.

GVL is mistakenly placed on a par with drywall, since the materials have different specifications... The main advantages of the products:

1. Strength. This indicator is achieved due to the composition of the product: in addition to gypsum, which occupies 80%, the slabs contain cellulose fibers - about 20%. Such a structure allows it to withstand serious mechanical loads and makes it possible to hang interior items on a vertical surface without fear of deformation of the base.
2. Moisture resistance. Gypsum fiber board has two main types: conventional GVL and special - GVLV. It is the second option that is used in rooms with high humidity: bathrooms, corridors, kitchens, loggias. But standard products are also moisture resistant enough to be placed in ancillary facilities with unstable humidity.
3. Frost resistance. With this material, wall cladding is possible in unheated premises... The resulting coating can withstand up to 14-16 freeze-thaw cycles without loss of strength.
4. Heat and sound insulation. Gypsum fiber prevents the penetration of extraneous noise and significantly reduces audibility in adjacent rooms. Also, the use of products contributes to improving the energy efficiency of a house or apartment.
5. Ease of installation. You can sheathe the walls completely with your own hands; this does not require special skills or complex equipment.
6. Fire safety. The boards are suitable for installation in rooms with a high risk of fire and evacuation corridors.

These indicators are inherent only in high-quality material, which has all the necessary certificates of conformity. That is why, when choosing products, you should give preference to trusted manufacturers.

Sheet dimensions

The dimensions of gypsum fiber boards are reflected in the relevant regulatory documents, for this type of product a special GOST R number 51829-2001 has been developed. Sheets are usually divided into two main categories: small-format and standard. The first option is used primarily for laying on horizontal substrates, while the second is perfect for walls.

For work with vertical structures, the following dimensions are used:

• width -120 cm;
• length - 250, 270 and 300 cm;
• thickness - 10 and 12.5 mm, in special cases it is possible to use panels of 15 mm and more.

Some manufacturers can produce products of other sizes while maintaining the basic parameters.

On a note! When choosing, they also pay attention to the edge: it can be straight or with a chamfer. The second variety is preferable, but it is much less common and has a high cost.

Since gypsum fiber wall sheets are finished, pay more high price for a material with a chamfer does not make sense

How to fix GVL to the wall

Internal work involves two main methods of fixing the slabs, each of which has its own characteristics and is suitable for a specific situation.

Frame mounting

This method is used for fixing GVL on bases that have significant drawbacks and irregularities. The lathing can be erected from timber or a metal profile, the choice of material depends on the type of surface. If the walls are concrete or brick, preference is given to a more reliable metal frame. With a wooden base, a bar is better, but it must be thoroughly dried and treated with protective preparations, therefore this method is used much less often.

Installing profiles

For the installation of GVL on walls, the frame method is more preferable. This is because the resulting design is suitable for additional insulation and concealment of communications.

To mount the guides correctly, the following technology is used:

1. The process begins after correcting the shortcomings of the base: it is cleaned of unnecessary objects and old coating, which may interfere with work or deform in the future. It is also necessary to cover up the cracks.
2. Basic work begins with marking. To decorate the GVL room, a standard profile step is chosen - 55-60 cm. For an accurate calculation, the size of the insulation is taken into account in order to exclude unnecessary trimming.
3. Installation takes place in the same way as drywall installation. The upper and lower guides are set first with the help of a plumb line. Next, the vertical posts are fastened to the suspensions, which are placed depending on the condition of the base in increments of 30 to 45 cm.
4. Jumpers are laid between the posts.

It is necessary to achieve the ultimate rigidity and reliability of the resulting structure. For this, the elements are attached to the wall with dowels, and all the parts are interconnected with self-tapping screws for metal.

When arranging lathing under gypsum plasterboard in apartments and houses, the installation of transverse beams is desirable, but not necessary, the strength of the sheets for residential premises is quite enough

Paneling

You can install gypsum fiber products on the crate according to the following instructions:

GVL is used for sheathing partitions, but is not suitable for creating curly details of arched structures, since it does not have the necessary elasticity and cannot be processed.

Attention! Screwing in self-tapping screws will require more effort than when laying drywall, so an electric screwdriver or drill is selected for work. Instead of screws, nails can be used, but only when creating a wooden crate.

Fastening with glue or self-tapping screws

The frameless method allows you to level the surface much faster, but it is used much less often, since it assumes the absence of serious deformations of the base (differences should not exceed 3-4 mm).

You can attach the GVL to the glue according to the scheme:

1. Plates are mounted directly to the wall only after preliminary preparation: it is necessary to completely eliminate small defects and gaps. You should also clean the surface from the old decorative layer, which will not allow the gypsum fiber to stick reliably.
2. For the procedure, a special glue is selected. It is not recommended to use unsuitable formulations, in this case the result cannot be predicted. The mixture is applied to the wrong side of the material, after which the part is pressed tightly and leveled. Due to the need to form a gap from the floor and ceiling, a gasket is laid from below.
3. The rest of the elements are glued in the same way.

In exceptional situations it is possible to use gypsum fiber board to level out more significant differences - up to 3-4 cm. In this case, the gypsum fiber should be fixed using a combined method : glue on the putty mixture with additional fixation with self-tapping screws. The composition is applied pointwise or linearly to ensure the alignment of the sheets in relation to each other without the formation of points of sagging. Screws are used to align and secure parts together.

Finishing

Refining the resulting surface can be carried out in various ways, but always after preliminary preparation:

1. Joints between adjacent panels are closed. For this, the seam is treated with a primer and filled with an elastic filler. If work is carried out in a recently erected building, then the sections are reinforced with reinforcing tape. This will avoid cracking in the future.
2. The seams are rubbed in order to level possible irregularities.
3. The surface is completely covered with a primer and dries well.

You should know! It is rarely required to putty GVL, so further work is carried out much faster.

The decorative finish is selected depending on the specific situation:

• The easiest way is to paste the wallpaper. All varieties are suitable for this, but in the case of joining, the seams should be glued with a special tape, especially when choosing a paper version.
• Painting will take a lot more effort. For work, compositions are purchased for water based, the number of layers depends on the desired result.
• The surface can be tiled. This procedure does not differ from the standard wall decoration: the glue is applied with a notched trowel, installation is carried out 4-5 rows of elements at a time.

GVL is an excellent option for walls, as it provides a durable and reliable base that can be clad with various materials.

Gypsum board is a homogeneous material of compressed reinforced gypsum and paper and looks like gypsum board. GVL differs from GKL in that it is not covered with cardboard. It consists of two layers, one of which is primed.

Today, gypsum fiber is widely found in the decoration of premises for various purposes, including those with strict fire safety requirements. Sometimes it is simply irreplaceable. Due to its strong structure, GVL has increased strength and the sheet is suitable for creating load-bearing surfaces. Like the gypsum board, it is put on glue.

The advantage of GVL is great strength, and the disadvantage is weight. Unlike gypsum plasterboard, it is so heavy that it cannot withstand strong stretching and deformation, it cannot be bent. The material is thicker and more expensive than the gypsum board. It is an environmentally friendly product with high soundproofing qualities. It is fire and moisture resistant, formaldehyde free, and has the highest heat capacity. GVL sheet is warm to the touch.

Where applicable, dimensions and markings

Like GKL, GVL is used for the construction of a suspended ceiling, walls and floor. Due to its properties, GVL is used in damp, poorly heated rooms and where increased sound insulation is needed. Experts recommend using it instead of tiles, even in rooms with constant humidity.

When installing the floor, the gypsum fiber sheet creates a strong and warm base for the topcoat on any basis - wood, concrete or expanded clay pillow. GKL is not very suitable for this.

The choice of GVL is wide. Gypsum fiber, which resists moisture well, is used in all rooms, including bathrooms and toilets.

Based on the size, GVL is divided into a standard and small-format sheet. Dimensions of a standard slab: length - 2.5 m, width - 1.2 m, thickness - 10 or 12 mm. Small-format sheet is smaller: 1.5 m - length, 1 m - width, and the thickness is the same. It is convenient and recommended for adhesive installation on the walls of bathrooms and toilets.

Marking with information about the longitudinal edge, the name of the type of material (moisture resistant or not), sheet dimensions, production date and the name of the company are applied on the back of the sheet.

👷‍♂️ Not less important information on this topic:

Gypsum fiber boards - suitable material for covering walls. GVL is attached to the wall in the same way as the gypsum board, in two ways - frameless or frame. In the first case, they are planted with glue, and in the second, they are attached with self-tapping screws. The choice of method depends on the curvature and condition of the wall covering. Sometimes the walls have to be putty, and sometimes a frame is needed.

Frameless installation of GVL

Frameless styling of GVL is used less often, although this method is not bad. The frame is not needed, but special glue is required. Installation is carried out in this way:

• When the recesses are up to 4 mm deep, the sheets are immediately glued to the surface with gypsum plaster. This is the so-called gypsum glue. It is applied to the sheet in longitudinal thin strips around the perimeter, and then tightly applied to the wall.

The glue is used for gypsum fiber board. In some cases, PVA glue is used, although this option is more suitable for floors.

• If there are more irregularities on the wall (up to 2 cm), glue is used. It is smeared around the perimeter and in the center of the slab with dots every 30-35 cm. When it is planned to attach shelves, cabinets or other furniture to the wall, glue is applied to the entire surface of the slab.
• If the wall is already completely uneven (irregularities from 2 to 4 cm), then strips up to 10 cm wide are first glued to it, and solid plates are already attached to them with plaster putty. Wall installation is done prior to finishing the floor. The air temperature in the room should not exceed +10 degrees. Before starting work, sheets should be at room temperature for 2-3 days.

For damp rooms, use moisture-resistant gypsum fiber.

Before starting work, the walls are cleaned of weak old coating. If required, it is strengthened with a primer and putty. Installation of boards begins after drying. First, the level checks the verticality of the wall and marks the places where the slabs will be installed.

Cutouts for switches and sockets are prepared in the GVL plates cut according to the marking. The height of the GVL should provide gaps in the lower part of about 8-12 mm. They will be closed by segments after the installation of the main plates. For greater reliability, the plates are tightened with self-tapping screws.

Putty and glue are applied with a notched gauge trowel. The level is controlled by a taut thread. The slabs are aligned with a mallet directly on the wall.

Plates are placed around the perimeter of the wall, starting from its corner. For cladding wooden walls additionally, self-tapping screws or roofing nails are used.

Frame installation of GVL

A frame made of wooden slats is made with a material with a cross section of not less than 3.0x5.0 cm.The transverse size of the vertical posts is 2.5x7.5 cm.The fastening step does not exceed the width of the GVL, the recommended one is 40 cm. The GVL is planted on self-tapping screws with a length of at least 30 mm in 25 cm increments (with a slab width of 1.2 m). Glass wool is taken for insulation.

Plates are installed starting from the middle of the wall. A small gap is left between them, about 5-7 mm.

The metal frame is much more reliable. It is made of galvanized guides and supporting wall and ceiling profiles with a thickness of 0.56-0.6 mm, and the installation is similar to the lathing for drywall sheets.

The assembly is carried out as follows:

• The surface is being prepared. The old coating is removed. True, not all masters advise this, considering it a waste of time and effort.
• Using a level, a plumb line and a pencil, mark the wall. For vertical racks, take a ceiling profile. The guides are mounted in areas adjacent to the floor and ceiling.

• The brackets are attached to the racks with self-tapping screws, and the profiles are aligned with a cutter with bending. The profiles are attached to the ceiling with dowels in increments of 60 cm or slightly less.
• GVL are installed from bottom to top or top to bottom with a small gap between them.

After installation, the resulting surface is treated with gypsum putty, the joints and screw-in screws are completely closed.

GVL: Pros and Cons

If you compare gypsum fiber with drywall, then immediately the identity of the materials is noted. They are produced from the same raw material (gypsum) and use different technologies. Both materials are intended for interior decoration. They have similar, high environmental friendliness, are equally resistant to moisture, and under certain conditions they are resistant to fire.

Thus, the material is chosen depending on the capabilities of the wallet and the purpose of the premises. GVL has the following advantages:

• Strength. This is a tough material. It can withstand severe compressive stress. Drywall in this regard is more fragile. GVL is tougher in work and does not crumble. Drywall breaks down during transportation, loading and unloading and absorbs moisture.
• Moisture resistance is one of the advantages of gypsum fiber.
• GVL is more environmentally friendly. The gypsum fiber structure does not deteriorate over time and does not create dust in the room.
• It is not flammable, whereas simple drywall is processed to achieve such indicators.
• Possesses the highest heat capacity and sound insulation. Where insulation and silence are needed, GVL cannot be replaced by anything.

The video shows the installation of GVL in the bathroom:

The disadvantages of GVL include the following:

• It is weak in bending and is not suitable for creating curved structures.
• It is not plastic, therefore it is not widely used.

GVL is a great material. It is perfect for interior work in any premises, including bathrooms, lavatories, installation false ceilings, construction of fences, partitions and similar structures.

GVL is purchased in a specialized store after consulting a seller or a specialist who will advise a suitable material. They buy it without any stock, since there is no material waste during installation.

In contact with

The problem of a lack of living space exists in more than seventy percent of modern families. It is quite difficult to solve this issue by purchasing a new, larger housing area. But there is a less expensive way to make an apartment cozy and functional - to divide the space into zones. There are several tricks for this, but we will talk about the most universal. This article will discuss how to build a drywall partition without much effort.

Calculation of materials and selection of tools

Any repair must begin with the development of an estimate and the acquisition of all the necessary components. At this stage, it is important to correctly calculate the number of "consumables" and choose a tool. This will help avoid unforeseen expenses and save valuable time.

To begin with, it is worth deciding what type of plasterboard partition will be built. In any case, a metal frame is required, but the number of plating layers may vary. In addition, the installation uses different types hcl. It depends on the operating conditions. For example, in humid rooms, only a moisture resistant sheet (green) should be used. Another nuance: constructions made of hl are not made sliding, but it is quite possible to install a door in them.

Payment necessary materials is given in table 1.

Table 1 - Components for the construction of plasterboard partitions (the calculation is given for 1 square meter of the structure with a single-layer cladding).

In addition, you cannot do without the following set of tools:

• laser level;
• plumb line;
• puncher;
• tracing cord;
• roulette;
• scissors for metal;
• hammer (rubber);
• screwdriver.

After the purchase is made, you can start marking and installation.

Assembly of drywall partitions

First you need to decide on the location of the future structure. Only then comes the markup turn. This stage is very important, since the slightest inaccuracies can significantly spoil the final result.

Make enough markup in a simple way: Set back a certain distance from the walls and place marks on all adjacent surfaces. After that, mark the lines with a level, which are connected with a tracing cord.

Now about how to properly install a plasterboard partition. The installation of the frame begins with the preparation of the profiles that need to be cut depending on the height of the wall. Then the guide profiles are fixed to the floor and ceiling and the rack-mountable ones are inserted into them. The step is chosen in the range of 0.4 m. Self-tapping screws are used for fastening. To ensure the mechanical strength of the future structure, an additional corner profile can be installed.

The next stage in the construction of partitions from gvl (hcl) is sheathing with sheets of material. The drywall is fastened with screws so as to avoid overlapping vertical joints. After finishing the installation of one wall, you can start laying the sound insulation boards.

The last item is the finishing of the partition. It represents a certain sequence of actions: sealing joints, putty, primer, finishing putty and decorative trim... Inexperienced repairmen can be advised the following:

• perform all work with an assistant;
• periodically watch video tutorials on installing drywall partitions.

Bending drywall for curved structures

Drywall is a material that is very convenient to use to create curly and openwork partitions. To do this, it will have to be folded using the wet or dry method.

The most common option is to fold the dampened sheets using a needle roller. To begin with, a template is cut out of cardboard or paper, which will have the shape of the intended design of a part of the partition. Further, the material itself is prepared according to the template. Important: hl should lie for a couple of days in the room to "accept" its humidity and temperature.

The side to be deformed is moistened and pierced with a needle roller. After that, the material is fixed until it dries completely, and then it is mounted on a specially prepared frame.

Do you want to diversify the interior, but do not know how to assemble a curly plasterboard partition? To do this, you need to cut the guide profiles, bend them along the selected radius and strengthen them. Curved sheets are mounted across the rack profile and attached to the frame. Finishing is carried out according to the same principle as for conventional installation.

After you have mastered the basic principles of working with HCL, you can try to complicate the task. For example, almost every resident apartment building faces the problem of placing seasonal clothing and footwear. An excellent solution will be the installation of a drywall dressing room. I would like to receive some recommendations from those who faced such a task during the renovation process.

Greetings, dear reader, and new blog visitor. TO walls in children's rooms we try to make the highest demands on ecology, sound insulation and durability (after all, children love to be naughty). Therefore, when choosing materials for decoration and construction of partitions in the nursery, you need to be careful. By the way, why are partitions in the room itself needed, what should they be in terms of design and correct zoning of the room? You can read about this article about.

Zoning the space of a children's room with a GVL partition

Guarantee safety walls of the nursery where our pranksters play, at home gym, where children lead an active lifestyle, as well as in hallways and closets, in which we most often store bicycles, scooters, skis, skateboards and other bulky equipment necessary for the vigorous development of a child, frame structures with gypsum fiber sheets will help.

What is GVL?

GVL is a pressed board made from a mixture of a gypsum connecting element and cellulose fibers evenly placed in it, which plays the role of reinforcement. This material is strong enough, reliable, has high fireproof and soundproof qualities. It is used not only for construction interior partitions and interior wall decoration.

Besides gypsum fiber sheets widely used for finishing door slopes and window openings and as a finish flooring in rooms with normal and dry humidity conditions. And where they can undergo cyclic moistening and drying, moisture-resistant sheets (GVLV) are used, which guarantee high resistance to moisture penetration.

Dimensions of gypsum fiber sheets

The most popular types of sizes GVL and GVLV(moisture resistant): 1200 x 1200 x 10 mm and 2500 x 1200 x 10 / 12.5 mm. Note that the latter are more often used for walls and ceilings. Due to its large format, there are significantly fewer joints on finished surfaces. Small-format sheets are more suitable for flooring, where the main thing is to create a smoother base, and in small areas this is best done.

Pros and cons of gypsum fiber sheets

Pros:

• Reinforced with cellulose fiber increased strength material.
• Light weight- a sheet of 1 m2 with a thickness of 10 mm weighs only 12.5 kg, due to its low load, it does not create large loads for the supporting elements.
• Gypsum-fibrous sheets environmentally friendly and fireproof.
• Capable of creating comfortable microclimate- absorb excess moisture and release it when there is a lack of it in the room (for the weak immunity of children, a comfortable microclimate is very important).
• Exception for finishing works most inconvenient wet processes that are provided for using traditional materials (and masonry mortars, concrete block, brick).

Minuses:

Of the minuses, it can only be noted that this finishing material is recommended for use only in heated rooms. But it is clear that the children's room will be heated, therefore, as you can see, in fact, GVL sheets have no drawbacks.

So, into the furnace? Of course, as you can see, GVL is better than the so popular GCR sheets (the popularity is more due to the fact that they appeared much earlier). However, it should be noted that GVL the price is slightly higher, and therefore those home builders who count every penny can obviously lean towards the sheets of gypsum board, and this will not be too catastrophic a loss, because we have partitions, not a floor.

And yes, it is also worth attributing to the disadvantages the fact that gypsum fiber sheets are so do not bend like drywall... But this is not a problem at all - after all, we have partitions, and if it is suddenly planned, then the bending strip itself can be made of gypsum board - the strength will not suffer from this.

Note: by the way, you did not consider the option of erecting partitions from? It is also good in its own way, easy to erect (thanks to special grooves, even those who have never held a masonry tool in their hands can cope).

Characteristics of gypsum fiber sheets

To check on GVL strength, company specialists Knauf a number of tests were carried out. They attached a 1 kg kettlebell to a cable and hit it on a gypsum fiber partition. Taking into account the length of the cable and the mass of the load, the impact force turned out to be 12 kg, but there were no dents or cracks on the surface of the GVL. Only after the second blow, in the same place, there was a barely noticeable trace. So you no need to worry about the safety of walls made of gypsum fiber board, even if a future grows in your children's room Olympic champion in boxing. Although, of course, this material has a tensile strength, it is still not brick or concrete.

Heat insulating material , placed in the structure of the frame made of gypsum fiber board, increases the sound and thermal insulation of walls and partitions. The most optimal solution is the construction of partitions with a thickness of 100 mm filled with 50 mm mineral wool and double sheathing of gypsum fiber board 2 x 12.5 mm. The sound insulation index of this GVL structure is Rw = 56 dBA (according to GOST, it must be at least 41 dBA for interior partitions).

Therefore, the wall will be a sure barrier from extraneous sounds and noises. Even if the family has ardent music lovers, you are guaranteed peace and quiet.
