Plasterboard - this cladding ceilings and boxes with slopes, and all sorts of curly design, the creation of visionary designers.And if the first moment of this material were opponents who do not trust the new technology, but now they are almost gone.After years passed, and assembled from GCR products have been successfully tested for strength and durability.An important parameter is the size of gypsum board and its appearance.Correctly pick it up, you can minimize the amount of waste and a good save.Next, read about how not to be mistaken with the size, select the type of GCR and distinguish high-quality material from counterfeiting.

Drywall: basic facts and material composition

With GCR performed the construction of "dry" technology, and thes

e lists are the basis and structure.And all the other elements are used for mounting, connection and decoration.Each sheet consists of gypsum plaster core flat framed cardboard from both sides and along the long edges.

as used cardboard, despite a small thickness, has increased strength.It makes the sheets sufficiently rigid and the core, made of plaster with special additives, can vary in composition to achieve certain goals.For example, it can make GCR moisture resistant, not fearful fire absorbs noise.

Types of Drywall and Their Applications

Studying the range of plasterboard of different brands, you will notice that the manufacturers are guided by the general principles.They emanate from the requirements for facilities and mounted structures existing at the moment.Most manufacturers produced several basic types of gypsum boards used in various fields.The most popular of them - the GCR and gypsum plasterboard.Details - on.

Plasterboard standard

It is also called the building (or base).These plates can be brick walls, sheathing, ceiling and wall frames made of wood or metal.Suitable base for drywall and the intricate design of structures.Limitations on use: Use only indoors (provided that the normal humidity).For the finishing works in the apartment often use this kind of GCR.It is easily distinguished by a pale gray color of cardboard.

Standard drywall

Plasterboard waterproof

This material, which is marked by gypsum plasterboard, apply in those areas where the humidity medium or high.The gypsum core added special modifiers, through which moisture absorption is significantly reduced.Furthermore, in such drywall not settled fungus.Therefore, it is used for work in the bathrooms and kitchens, attics of residential premises, loggias and balconies, where there is heating.

more moisture resistant plates made of slopes.And if you apply a waterproofing lubricative type, they can coat the walls in the shower or swimming pool.It should be noted that it is not necessary to apply GKVL only where damp.The standard size of a moisture-resistant drywall and increased strength allow its use for covering any construction in the apartment or house.Color linerboard these green plates.

Waterproof plasterboard

Fireproof gypsum plasterboard

This material (marked GKLO) in functionality similar to the two previously described - it is treated in the same way and bent.Due to special additives, gypsum core of the gypsum board can be twice as long withstand high temperatures.With this particular smoke and fire can not spread rapidly.For wet areas, there are special fire-resistant drywall brand.

GKLO applied for the construction of fire-prevention walls, and they sheathe cable channels, ventilation shafts, steel structures.You can use fire-resistant sheets and when it is necessary to fence off the premises a separate room.Typically, the material used in offices, factories, facilities for public use.Cardboard lining has a lighter shade.Some manufacturers make it red - for example, the company Rigips (plasterboard brand RIGIMETR FIRE-Line PLUS).

Fire-resistant drywall

Plasterboard design

This material also has other names: arched, flexible.It was invented for the construction of complicated structures, which need to bend parts with a small radius.For example, it may assist in mounting arch elements or a composite false ceiling.Flexible plasterboard plates differs little thick - from different manufacturers, it ranges from 6 to 6.5 mm.Furthermore, the core is reinforced with fiberglass mesh, which can go in several layers.

Construction sheathe two layers of sheets.When installing do not require any prick or wet drywall - all done "dry" method.If there are special requirements for fire safety, you can use flexible sheets HEP manufactured by gypsum plasterboard.They have high fire resistance.

Plasterboard ruggedized

This material (reinforced) is designed to withstand heavy loads.For example, you need to hang on the wall something heavy - reinforced sheet fasteners will not fall.Apply this drywall in any premises.Several manufacturers produce slabs reinforced with additional properties.For example, they can be flame resistant or water proof.As an example GKLVU gypsum plasterboard from the company and from the company Knauf Diamant.At last there is a manufacturer's product, called "massive."They have a thickness of 25, 20 and 18 mm.We've taken them also belong to the high-strength plates.

panels Special

addition to these GCRs, the different types of plasterboard, designed for specific conditions.For example, are materials that:

  • have an increased noise protection properties;
  • are protected from the wind (it is needed for finishing the external walls);
  • good conductor of heat (of which make lining of warm floor or ceiling cooling);
  • have the property of heat insulation;
  • include multiple layers (vapor barrier, the polymeric foam layer);
  • shield X-rays;
  • capable of absorbing electromagnetic waves.

There are other varieties of plasterboard - for example, "Akvapanel", which the company produces Knauf.Their core is formed not on the plaster and cement based on both sides of a glass frame.This building material for exterior facades even approach, as it is well protected from most of the negative factors.

Another example worth citing - it gipsovolokno (abbreviated GVL).Comprising such a slab of plaster base with the addition of cellulose fibers.It is very tough and durable, not exposed to the fire and has a flat surface.With this primer before finishing is required.Gypsum fiber sheets are used in many cases - for example, the installation of dry floor, outdoors (including assembly designs of frame houses).You can use them in those areas where damp.

types of drywall edges

Almost all brand distinguishes drywall finished cardboard edge along the long side of the sheet.It is usually the edge is thinner, which allows the dock seal the sheets these places putty, and use for reinforcing paper, fabric or fiberglass.It turns smooth and durable surface.On the wrong side of the gypsum board are symbols which give to understand what type of edge is used in this list.


PC - straight edge configurations.


CC - edge, which on the outside is thinner than on the inside.


PLC - edge, which is outside of the semi-circular.


PLUK - edge, a semicircular and thinned from the outside.


ZK - edge rounded on both sides.

When plating in multiple layers (as well as technical areas) such chamfer is overkill - it is better to choose the sheets with a straight edge.Thinning edge is to choose only for finishing, followed by filler.

Sheet size drywall

length along the length of the standard size of a sheet of drywall - 2, 2.5 and 3 m. However, there are manufacturers that produce sheets of a length of 1.5, 2.7, 3.3 and 3.6m. In addition, if necessary, may be cut at the factory drywall ordering own dimensions.

If you need oblitsevat the wall to the ceiling, then it makes sense to buy long sheets.So get fewer seams (horizontal they did not).And not have to put the jumper.But if you have a ceiling of 2.7 m, and the length of the sheets - 3 m, it does not make sense to buy them.It will waste a lot, and fuss with a lot of long heavy plates.Without the helpers do not succeed.Before buying a three-meter-sheet is required to check whether they will be included in the front door and the apartment and into the elevator.Sometimes it would be preferable to order a few sheets of different length - everything is solved individually.

Standard length of the sheet of drywall: 2;2.5;3 m.


This option is typically a standard - 1.2 m, which is why the frame and racks have a pitch of 0.4 or 0.6 m. Now on sale appeared comfortable and lightweight sheets of small size, widthhalf (0.6 m) and length is 1.5 or 2 m. They are well placed in a car, they can be mounted alone, but they are best used in small planes.Otherwise, too many stitches out.It is narrow and flexible drywall (brand GKLD from gypsum plasterboard company has a width of 0.9 m).

The standard width of 1.2 m.

Thickness Thickness of drywall sheet sizes are 6, 9, 12.5 mm.The options are 6.5 and 9.5 mm.Reinforced and fireproof plates can be produced in thickness 15, 18, 25 mm.Thin (6 mm) sheet is used for the manufacture of arches and other similar structures.If the radius of curvature large, take them unprofitable - for flexible drywall expensive.Him and requires twice more - in fact the product of a two-layer do.

Sheets facilitated type 9 mm thick intended for ceilings, so it does not deform in the space between the profiles.For walls, they do not work - not as durable.However, the ceiling for experienced masters prefer to take the sheets thicker - 12.5 mm (wall).They are flexible and strong, have proved effective in the mounting profile with a pitch of not more than 0.6 m. This thickness drywall most in demand, and it fits better the ceiling, as experience has shown.The plates and screws are screwed better, and lighting them stronger hold.For the walls they can be mounted in multiple layers - so get a reliable and durable.

most demanded thickness of a sheet of drywall: 6;9;12.5 mm.

manual for proper selection of drywall

Now tell how to choose the drywall.Having come into the store or on the market, you should carefully examine the GCR for quality.However, well-known brands are not usually reliable summing buyers, but they sometimes produce faulty party.But plasterboard will after manufacture and transport ride and soak in the warehouse, and in different conditions.Sometimes sellers simply dump the lists on the street under a canopy or store them on a cheese warehouse.

If pallets GCR put on each other, you can crush the core, the deformation of the sheets formed scratches and dents.A sloppy stevedores negligently volokuschie long sheets, cardboard liner damage.As a result, there are many marriages that inattentive buyer can not see.

So try to do the following:

Council 1. Get drywall in a major retail outlet.There he lay for a long time definitely will not.

Council 2. a look at the warehouse, see the storage conditions.If it is wet, the material does not take.

Council 3. When loading and unloading plates Make sure that it was done carefully.

Sovet4. Inspect each plate for dents, scratches and other defects.

They can be such:

  • Outside and inside the sheet dented, damaged corners - signs of damage to the core;
  • paper in the middle of lagging behind, inside it is wavy;
  • core crumbles on the short side;
  • panel is curved horizontally or vertically;
  • thin edge of the edge is folded back;
  • plate is cut at right angles (factory marriage).

If you need a lot of stuff, you can make a test purchase - one sheet.Cut it into strips with a knife, and see whether a homogeneous core, even if cut, whether foreign inclusions.And certainly not to make a mistake, take the products of reliable brands: gypsum plasterboard, Knauf, Lafarge, Rigips.
