GCR what it is: types of plasterboard laminated in construction, composition and characteristics, perforated

Plasterboard is an excellent and practical material for surface finishing in making repairs Those who are professionally engaged in furnishing, finishing and plating rooms, walls that definitely needs to know what the GCR and how to work with this material, knows the types and finenessGipsokartonnyh sheets. The construction market is diverse in terms of the choice of material for decoration and construction, but GKL is a universal finishing material.

GKL: what is the scope of its application

Looking at the drywall sheets in detail, it can be concluded that this is not only the most popular, but also the universal material.

GKL are made of two components - cardboard and gypsum.

Many prefer to choose the GCR as drywall characterized versatility and functionality

Building plaster within the sheet( base), solid high density paperboard( liner) in plate form.

Areas of application:

• Wall and room decoration;
• Installation of suspended ceilings;
• Creating partitions and openings;
• Soundproof design;
• Warming of walls of houses and office premises;
• Hiding the unevenness of walls and ceilings.

Application of drywall in construction is very extensive, we'll talk about this in detail.

Drywall composition

In the production of gypsum boards, there are standards in which, depending on the type, the composition of the GCR differs.

Learn the composition of gypsum board can be in a specialty store in Consultant

Description of composition percentage:

1. Building plaster - 90%;
2. Cardboard pressed - 5%;
3. Water, glue, dyes - 5%.

Drywall is environmentally friendly material, unlike OSB( oriented chipboard), which includes toxic substances( formaldehydes and resins).

In the manufacture and production of gypsum boards, according to the standard, gypsum of two grades G4 and G5 is used.

Depending on the modification and properties of the resulting drywall, there are varieties of GCR, for example, GKLO( gypsum plasterboard sheets of increased fire resistance), used in flammable and industrial premises, which include chemical additives that increase refractory properties.

Drywall: material characteristics

As with any building material, the gypsum board also has its own characteristics, which include. Let's consider them in detail.

Underlying incorporated:

• sheet size( length, width and thickness);
• Drywall material;
• Weight( from 16 to 35 kg);
• Strength for deflection, which is the main technical component;
• Color of the sheet( the main ones are white refractory, green moisture resistant);
• Edge shape( straight, tapered, semicircular, rounded);
• Flameproof;
• Environmentally friendly.

The sheet thickness is selected only from the destination. For example, for sheeting of a suspended ceiling, it is recommended to choose a thickness of 9.5 mm, since it will not experience high loads and is cheaper. For the installation of walls and the creation of partitions a thickness of 12.5 mm is used, since the sound insulation and strength of the wall depend on the thickness.

Plasterboard is perfect for the walls and ceiling of the apartment as he environmentally friendly and safe for the health

weight of one sheet is calculated based on the material, width, length and thickness of the sheet.

Color characteristics play a significant role in the selection of drywall. For the convenience of the buyer, almost all manufacturers, depending on the sphere of use, paint the surface. For example, the manufacturer of the GCR Knauf, the conventional GCR is painted in gray, green waterproof, fireproof in dark gray, and a combination thereof is painted in dark green.

It is also worth noting that there is also a small-format drywall.

The difference in the ecological compatibility of sheets depends on the composition of the materials used and is one of the main technical characteristics of sheet control before entering the market. By the way, Knauf is the most environmentally friendly gypsum cardboard today.

In order for the wall to be stronger and quieter, choose the thickest sheet and note, when installing, try to use solid sheets and use the entire useful area of ​​the plate.

Properties

plasterboard Plasterboard sheets are different properties and the material from which they are produced, in this regard, in Russia in 2001, it was introduced a special standard 51829. Depending on the application, the leaves began to be subdivided into species that depends on the basic properties of the drywall.

Learn about the basic properties of drywall you can on the Internet or open spaces in the home improvement store

Among them:

1. Density standard drywall is 7,2x102 kg / m3
2. Sustainability( presence of harmful impurities);
3. Breathability( regulation of humidity and indoor climate).

Before buying GCR sure to ask for information about the manufacturer, null, check for eco-labeling "Leaf of Life", and it is desirable to get acquainted with the composition of the materials used.

Types drywall

Depending on the scope and purpose, gypsum boards are divided into two basic types and 4 subspecies. GCR and GVL( gypsum-fiber sheets) are common.

If you need to quickly and accurately to sheathe the walls, then for this purpose are perfect simple plasterboard

types of drywall and their scope:

• GCR - a simple plaster board, in which the structure includes plasterBase reinforced with cardboard. It is used for wall covering, arrangement of partitions, in houses with a moderate climate and normal humidity of air.
• GKLV is a moisture-resistant plasterboard sheet used in rooms with high humidity. The peculiarity of this kind is that it prevents the formation of mold, mildew on the wall surface, and retains its shape in extreme conditions. Suitable for walling in private houses and even baths.
• GKKVO - plasterboard, which combines waterproof and fireproof properties. It is used on very responsible construction sites, for safety against fire and high humidity. The main disadvantage of such sheets is the high cost.
• GKLO - gypsum cardboard with an increased limit of refractoriness. The peculiarity of such sheets is the provision of norms and standards of fire safety. It is most often used in educational institutions and social facilities( hospitals, educational institutions, etc.).

All types of gypsum boards data are distinguished by their environmental friendliness, production quality and comfort of work, since they have a lower weight than, for example, oriented strand board( OSB), which is also harmful for residential use.

Depending on the purpose of plasterboard sheets exist 3 kinds:

1. Ceiling - has a maximum thickness to increase the noise suppression characteristics is used for mounting false ceilings;
2. The arched gypsum board has a minimum sheet thickness, is suitable for rough finishing works;
3. Wall GCR - has a standard thickness of 12.5 mm is used for the purpose of work( covering ceilings, walls, partitions mounting).

When the wall is covered with a conventional GKL, it is combined with laminated plasterboard panels, with a vinyl coating, with a variety of colors and colors.

advantages and characteristics of laminated plasterboard

laminated plasterboard - a new word in the field of decoration and building materials, as it appeared on the market recently. Its main purpose is decorative decoration of walls and ceilings.

There are almost no varieties of laminated plasterboard. The main difference is the color( design), shape and thickness of the sheet.

In the photo you can see how it looks and how it differs from the usual sheet. By its characteristics, it is not inferior to moisture-resistant and fire-resistant sheets and is used even in the walls of the bathroom. Laminated gipsokartonnye sheets are produced on the technology, reinforcing the fabric basis, which is much stronger than the cardboard base.

Originally transform the interior space is possible by means of laminated plasterboard

advantages inherent in laminated GCR:

• variety of colors and shapes( stone styles, wood, etc.);
• no need to use screws( mounting plates is possible thanks to special brackets and clamps;
• ease of cleaning and maintenance;
• easy to install and dismantle if necessary;
• After the installation is no longer necessary to perform additional work( plaster, adhesive wallpaper, paintingwall);
• increased strength and protection sheet from scratching and damage;
• Excellent air-conducting properties of the sheets, permit them to "breathe" and thereby control the humidity inIndoor;...
• Application sorts furring material for LGKL mounting
• High ecological

laminating films of PVC plasterboards of different thicknesses, allow to give the structure of impact resistance and wear resistance

Before acquire such a material, it is necessary to take into account the important technical points:

1. When installing door and window sills, it is necessary to use only special glue with the characteristics inherent in sealants;
2. Cleaning and washing of such panels is permitted only by liquid detergents not having solid particles( powder);
3. It is not allowed to install in bathrooms and toilets with high humidity;
4. When creating decorative floors, it is recommended not to remove the post-installation film.

way, laminated gypsum panels are used not only for the walls and ceilings, but also for the manufacture of furniture, decorative elements of the interior and the facade of buildings.

What is GCR in construction

construction and finishing of buildings and premises shows that gipskokartonnye sheets in our time occupied a leading position in the market of finishing materials, since they are distinguished by a large range of products, low cost and compliance during operation.

experts recommend for finishing the surfaces to choose drywall because make repairs to its use will be under the force of even a novice

Applying FCL together with the heater can achieve thermal insulation of residential premises that is not afraid of low temperatures and severe frosts of ourClimate.

In this regard, almost all the construction sector has switched to plasterboard material, especially for Western countries. For example, in the US, almost all private houses are built entirely of plasterboard. Drywall sheets help builders and designers to solve a lot of customer's intentions, in particular, covering of ceilings, walls, arrangement of partitions. With its help you can build small warehouses. In Russia, the main producer and seller of plasterboard sheets is the company Gipsopolymer.

The main differences between gypsum boards from other materials are:

• Universality of application( a variety of applications);
• Low production cost, which allows entrepreneurs to establish the production of drywall;
• Assortment in the market of building and finishing materials( comparable with the choice of wallpaper or linoleum);
• Convenience and comfort of work( the material is amenable to work as an experienced builder, and an ordinary person);
• Variability in the choice of fastening sheets( screws and screws, staples, klyamery).

Thanks to these parameters, you can clearly see what is different about the material.

Differences and characteristics of perforated drywall

One of the varieties of GKL is a perforated gypsum board that differs markedly from the usual one. Its main feature is good acoustic properties. They are used where it is necessary to achieve minimal sound vibrations, echoes( stadiums, cinemas, etc.).

perforated plasterboard advantages that it differs sufficiently high strength and good sound insulation

made from cellulosic webs fleecy coating on the sheet surface. Properties similar to conventional GCR, except for high sound absorption.

Characteristics of perforated drywall:

1. Ease of installation and maintenance;
2. Absorption of sound by a resonant method;
3. High strength and durability;
4. Provides optimum climate and humidity in the room;
5. Need for a special tool for installation;
6. After installation, jointing is required;
7. High cost.

in ordinary residential areas, a drywall hardly used, and used in exceptional purposes( elevator shafts, rooms with ventilation equipment, as well as pumps and transformer equipment, life giving increased noise).Varieties perforation gypsum board: round, square and rectangular.

Features GCR: what it is( Video)

Construction of GCR help reduce the cost of decoration of rooms and houses, and increase the efficiency of decoration, as well as to ensure compatibility with other materials, without harm to health. The newest trends and prospects for the use of gypsum plasterboard sheets are determined by lower cost with the same increase in the quality of erected structures.
