GCR: what it is, gypsum fiber board, gypsum plasterboard, GKLO

The term "dry" construction has been known since the last century, but in our country it began to be used only in the 90s. The person is not associated with renovations or construction work can ask a question, GCR - what is it? GVL, GKVL, GKLO - all of these terms is not surprising confused the novice builder. Plasterboard or gipsovolokno used to align geometries premises without the use of large amounts of cement and plaster.

GCR - what is it? GVL, GKVL, GKLO: similarities and differences between concepts

The principle of facing boards got its popularity due to a number of advantages:

• several times increases the performance of finishing works;
• drywall and gipsovolokno made from environmentally friendly materials;
• the possibility of mounting a closed pipe spreading room;
• in loading component is reduced several times overlap;
• a slight amount of dust during installation;
• It does not require the use of special concrete mixers;
• dry wall surface when finishing is not damaged.

Important! In the "dry" construction of all the materials easily matched by the geometry of the room. Perform work under the force of even a paralegal professionals.

So what's the difference between these concepts?

GOLS girpsokartona harder and stronger, so it should be used for the finishing of surfaces with enhanced mechanical influences. In addition, due to the homogeneity of its layer can be cut in any direction. Plasterboard has lower strength, cut line on it can be done only transversely, since the longitudinal reinforcing penalized saw cut paperboard layer.

One of the remarkable features of GCR - when moistened sheets of plate become necessary, and when dry - restore their original characteristics. Due to this, drywall are particularly fond of the designers to perform complex architectural forms a curved design. It is commonly used drywall with a width of 600 mm for curved designs.

Drywall - an ideal foundation wall before further pasting wallpaper. No additional processing is not required, only the nail heads must be covered with a neutralizing compound to prevent corrosion. You can instead Wallpaper paint panel paint oil or adhesive base.

There is no single opinion, which is better, drywall or gipsovolokno not. Both materials exhibit excellent performance. The main thing for a variety of conditions to choose the "right" material.

What is the GCR in the building? Definition and classification

GCR - sheets of drywall, plaster consisting of the middle lined with cardboard. Standard sizes 1200h2500 millimeters. This is a great assistant for alignment of wall surfaces, create a partition, perform arches, multi-level ceiling structures. Easy installation makes it quite popular in the finishing work.

Drywall is available in four versions:

• conventional drywall;
• Gypsum plasterboard. What it is? It is moisture-resistant drywall surface-treated with a special compound. Manufacturers paint it green;
• fire-resistant drywall or GKLOColored red. Resistant to an open flame for 20 minutes;
• universal drywall or GKLVO - and it has the refractory, and moisture-resistant quality.

GVL The concept: what it is and assessment professionals

GVL is very similar to drywall, but in the gypsum sheets include cellulose reinforcement and special additives. Such sheets are not lined cardboard, they are homogeneous texture. Their strength is four times higher than that of the plasterboard. The edge may be straight and standing seam. can not perform from GVL figured elements, since they are difficult to bend.

Used for the production of gypsum brand G4 or higher. The material has all the requirements of environmental safety. With GOLS can arrange interior partitions, complex ceiling structures, To correct the geometry of the walls. They are suitable for finishing work in industry, social and residential facilities, health care and child care centers, health resorts resorts.

Let's try to understand the characteristics of the gypsum fiber board. What is it helps to understand the classification of materials. Gipsovolokno is the following varieties:

• standard GVL;
• gipsovolokno with additional processing water-repellent composition (GVLV) for rooms with high moisture content;
• GVLV EP or Knauf superfields.

GCR and gypsum fiber board: what is the difference? Comparative characteristics

The most fundamental difference - in the production of the sheet. Due to its properties, GVL is resistant to shock, so it is recommended to apply for the manufacture of partitions. Furthermore, it is easy to cut, the sections can be performed in any direction. Small structures is the best material.

Comparison of characteristics of GCR and gypsum fiber board, the main indicators of the differences:

The main differences from the GVL GCR - is the technology of their production. For the manufacture of the first, gypsum is pressed, it is glued cardboard. In the production of gypsum gipsovolokna mixed with cellulose, which acts as a reinforcement. The composition is administered strength additive and adhesion, whereafter the mixture is compressed.

Plasterboard is convenient to apply before further trim wallpaper or other materials. Due to the smooth surface, the walls do not require additional treatment.

GCR and gypsum fiber board: it is better and for what conditions are suitable?

With the help of GCR or gipsovolokna can solve all major tasks to fulfill or finish space zoning. For a long and successful operation it is important to use materials in accordance with their specifications.

Plasterboard:

• durable sheet is suitable for alignment of wall and ceiling surfaces, it holds its shape well, not easily deformed;
• flexibility and elasticity allows you to create complex designs, arches of complex shape;
• simple and fast installation using screws or glue;
• when cutting material may crumble;
• GKLO - resistant to open flame.

gipsovolokno:

• has a high strength, it is advisable to lay on the floor as a rough surface;
• GVL has increased strength and a considerable weight. Resistant to temperature changes;
• less flexible than the GCR;
• frost 3 times higher than that of the drywall;
• increased moisture resistance. GVL has additional sound insulation properties.

In some cases, it is recommended to use drywall or gipsovolokna? It is better to opt for decorating?

ceilings

GCR - lightweight panels more suitable for ceiling surfaces, they do not create an additional burden on profile systems. Light weight boards making them comfortable enough to install. Furthermore, the plasticity will perform multilevel curvilinear forms.

septa

If it is necessary to perform simple elements with straight lines, GVL is selected which has sufficient rigidity and a good sound quality. If you want to perform architectural lines with curved edges - it is better to choose gypsum plasterboard.

Bathroom

GVL has high moisture resistance, especially to perform the subfloor. Gipsovolokno does not absorb moisture, the panels are not subject to deformation. Plasterboard with a water-resistant characteristics are also suitable for wet rooms, but only as a rough finish to wall surfaces.

floors

Due to its strength, to perform dry screed GVL sex should be used.

two layers gipsovolokna recommended to lay. As the "finishing" can be any floor covering. Due to its good heat capacity GVL can be used during installation underfloor heating.

Finishing a wooden house

For interior surfaces of wooden houses used as intended and drywall, and gipsovolokno. To improve the fire resistance should be selected refractory materials GKLO. Use drywall or gypsum fiber board on the walls - depends on the tasks of the allocation of certain areas in the room. Basic geometric trim can be made of gypsum fiber board, and arch design - using plasterboard. Combined finishing will save money on expensive materials.

Comparative material specifications

To perform high-quality finishing materials, experts recommend acquiring known manufacturers only in specialized retail outlets. Only in this case the products will be of high enough quality.

The geometrical dimensions

Currently there are no documents regulating the size of the FCL. Manufacturers received tacit standardization drywall, highlighting the main dimensions.

Customized sizes can be produced GCR 1500h600 millimeters sheets. In addition, the sheets can be ordered up to 4 meters.

Separately, we must talk about the FCL for the walls. The thickness of 12.5 mm is used for simple alignment surfaces. For ceiling structures use a thickness of 9.5 mm. The thinnest plasterboard used for curved structures. If you need to partition with additional sound insulation, you can perform the installation of two sheets GCR.

Dimensions moisture resistant plasterboard in a conventional discount or individually performed with a thickness of 9.5 or 12.5 mm. Manufacturers offer drywall with high impact strength and moisture resistance 13 millimeters thick.

GVL has increased strength and elasticity. Currently, two types of gipsovolokna on the market: standard and moisture resistant. Manufacturers offer a GVL in the following geometric parameters (in mm):

GVL sheet sizes for walls in the standard version: 1500h1200h10 mm

Possible to produce gipsovolokna on non-standard sizes (in mm):

• with a length of 500, 1000, 1200;
• width: 500, 600;
• the thickness may be up to 25.

Weight GCR and gypsum fiber board

Weight plasterboard sheet is in direct dependence on the thickness and physical characteristics. The standards to denote the weight of one square meter of drywall:

• at a thickness of 6 mm - square meter weighs 5kg;
• respectively to thicknesses of 9.5 and 12.5 mm weight of 7.5 and 9.5 kg.

The calculation sheet of drywall is not difficult.

Individual sizes are determined in a similar manner. Knowing the area of ​​the sheet GCR weight of 1 m2 can readily determine all other parameters.

For GVL weight of 1 sq.m. 10 and for the thicknesses of 12.5 mm is equal to 10.8 and 15.6 kg respectively.

The difference with the GCR more than 2 times per 1 square meter. Therefore, for the installation of ceiling structures GVL use is not recommended.

strength of materials

Due to reinforcement of cellulose, GVL has increased strength and rigidity, unlike the drywall. However gipsovolokno significantly inferior in bending GKL. For curved structures can not be used GVL. Plasticity adds plasterboard fragility, during transportation, loading and unloading should be very careful to move the sheets. This is the main difference from the GVL drywall.

Gipsovolokno is a homogeneous material, in contrast to drywall with a cardboard covering. GOLS density 1250 kg / m³, which is significantly higher than the density of gypsum board. Accordingly, gipsovolokna strength above. Parameters tensile strength in bending loads GOLS 5.5 MPa, at GCR - 2 MPa.

combustibility

The following requirements apply for the GCD Fire-Performance the following classification groups:

• G1 - readily flammable;
• IN 3 - flammability;
• D1 - low smoke generation;
• T - low toxicity.

As part of GVL 80% gypsum, respectively, its technical fire safety options above.

• G1 - readily flammable;
• IN 1 - hard voslamenyaemost;
• D1 - low smoke generation;
• T - low toxicity.

Thus, we see that fire-technical characteristics gipsovolokna above. GOLS be applied field and the possible evacuation of people in areas with a high fire hazard.

frost

Manufacturers guarantee for gipsovolokna to 15 operating cycles without loss of physical properties. At that time, both for the GCR only 4 cycles of freezing and thawing. This gives additional benefits to GVL GCR.

Plasterboard feels better at ambient temperatures without sharp fluctuations, it was originally designed for interior surfaces.

Water absorption

Water absorption for gypsum board moisture resistant characteristics, must not be higher than 10%. If necessary, one can calculate the softening component which is a ratio of compressive strength of the sheet in the wet and dry state.

For GCR this parameter is 0.45. Indicating that the low strength of wetlands. this is 1 to GVL.

Thermal conductivity

Indicator thermal conductivity for GCR varies 0.22-0.25 W / m * K. This is a good value, thanks to which during the finishing work can simultaneously increase the thermal insulation space, which will significantly reduce the budget for the execution of works. Moreover, if during assembly to provide an air layer between 3-10 millimeters, it will save additional heat. To improve the thermal conductivity properties can be made from any layer of insulation.

Coefficient of thermal conductivity for gipsovolokna is 0,22-0,36Vt / m * K. Thus, we see that the value of thermal conductivity for GVL higher, which makes it ideal for finishing wall surfaces and floor coverings.

The ability to load and GVL GCR

Plasterboard is able to withstand loads of up to 30 kilograms per square meter. GOLS much stronger drywall, respectively and the load component has a higher 3 times.

Scope and GCR GOLS

In choosing the material should be based on the specifics of the room. For alignment geometry wall and ceiling surfaces, performing sub-floor in industrial, public areas should be selected gipsovolokno.

In accommodation ceilings figure outlines better fulfill plasterboard partition walls and direct geometry - from GVL, for curved arches, you can use the FCL. Buyers alike speak of the positive characteristics of both materials. The main thing is to choose the right subject humidity and the material strength.

In terms of environmental safety - and GCR and gypsum fiber board have the same properties. Thermal conductivity, especially at the complement insulation layer, almost the same. In addition, both materials are non-toxic.

In recent years, manufacturers will improve GCR and gypsum fiber board, giving them a better quality. For wet rooms should use moisture-resistant drywall or gipsovolokno. They are at high humidity can absorb water vapor during drying - to give the surplus.

GVL and GCR - sheets, with which in a short time without much dust and dirt you can finish the whole room, adding to its excellent sound and thermal insulation.

Partitions and walls of the GCR and gypsum fiber board

As plasterboard, gypsum fiber wall is used to align the wall surfaces or walls of the device. In areas with high humidity, use moisture-resistant gypsum fiber board. Gipsovolokno - the best material for finishing works in poorly heated homes and rooms where you need higher sound insulation. When the GCR mounted on a wall, you can use the frame or frameless method.

In the first case previously performed installation frame of metal or wood parts, which can be attached to a heater if necessary. Metal construction is more secure. After mounting the sheets must proshpaklevat and perform the final finishing wallpaper or other materials.

In frameless plasterboard or paneling walls GLV as fastening use a special glue. This method is suitable for surfaces with a deviation of no more than 2 centimeters.

It is important! Sheet panels GCR and gypsum fiber board must be in the room for at least 3 days prior to installation.

Arrangement of partitions of GCR or GVL should begin with a road marking. Then, the assembly of the main frame of metal profiles, which are mounted on plaster panels. In the case of shaped structures should only be used drywall. It is more malleable and easily curved cutting.

The assistance for making the decision to change interior you can see the video interesting design and gypsum fiber board walls with GCR.

The ceiling of GCR and gypsum fiber board

Installation of the ceiling of GCR or GLW - the process is fairly labor-intensive. But with it come to life interesting design solutions. Even in the simple geometry using sophisticated lighting can give the room a modern direction. All wiring while hiding behind the frame.

The ceiling of GVL is performed only in straight lines. You can close the entire ceiling surface sheets. And only the perimeter of the ceiling can be performed using gipsovolokna installing hidden in niches LED backlight.

GCR mount technology on the ceiling of the carcass is performed on the metal guide way. With gypsum board can be arrange complicated multilevel structure.

Suspended ceiling after mounting, proshpakevat and paint finish paint.

Other areas of application of GCR and gypsum fiber board

Universal Drywall and gipsovolokna sheets allow to apply them to solve various problems in the finishing work. For example, the device of the GCR slopes and doors - in a short time can end finishing with minimal effort window and doorways. Will only proshpaklevat and paint surface.

Execution of the GCR arched openings should be made on preformed frame or frameless method. Ornamental design, performing the role of zoning, established only on the basis skeleton.

Application gipsovolokna to the floor is possible due to its high strength and perception to the loads. To begin, you must perform a pad of expanded clay, then laying GVL. To improve the thermal insulation assembly to produce a 2-layer gypsum fiber board.
