Plasterboard: types, characteristics and prices
Plasterboard interior can be used for technical purposes (leveling of uneven walls, construction of false walls, partitions, flooring)and decorative (organization of the suspended polotka, multi-wall design, decorative three-dimensional elements).
itself drywall - a material non-flammable .The only element of plasterboard, which are exposed flame - lined cardboard sheet.However, due to the fact that the combustible and refractory core board are connected end to end, i.e.between them there is no air cushion, the cardboard will not burn too - is possible only charring of the material layer.
IMPORTANT!Any type of drywall is not flammable, but do not confuse the ordinary heat-resistant and flame-resistant drywall GCR - material reinforced with special additives to work in areas with a high risk of fire.Normal sheet of drywall from prolonged exposure to high temperatures will begin to crumble as soon as the water contained in the cast (about 17%) completely evaporates.Fire flame drywall resists longer.
How to choose a drywall
Choice drywall should be based on its intended use: any type of work in the room will fit a certain kind of drywall.
Choice brand and size of the sheet - secondary tasks.
So the selection criteria should be drywall
- kind of work carried out by you;
- thickness and length of the sheet;
- weight of the sheet;
- type of sheet edge;
- brand / manufacturer;
- price of the material.
Now, first things first.
Types drywall GOST 6266-97
IMPORTANT!Each type of drywall according to generally accepted international standards has its own color.Pay attention to the color-coded material in purchasing.
No additives, designed for indoor use, the level of humidity does not exceed 70%: use when working on interior partitions, decorative and sound-absorbing structures, suspended ceilings (secrete a special type of drywall - a ceiling).Colour material - gray (rarely - blue).
insensitive to humidity drywall containing hydrophobic and fungicidal additives, suitable for wet locations.Plasterboard waterproof can be used for wall cladding and ceilings in kitchens, bathrooms, bathrooms, used as a base under the floor (a special kind - sexual drywall) and for covering window slopes.Material color - green.
IMPORTANT!Water-repellent properties of this type of drywall enhances special impregnated cardboard, gypsum plasterboard somehow be isolated from moisture, for example, painted or tiled drywall in a wet basement "feel" themselves will be much better.
Marking: gypsum plasterboard
IMPORTANT!Drywall floor more often used in the technology of "dry sex": outdoor plasterboard placed on a prepared base - frame filled and fastened with screws.The release of such material has been far from each manufacturer.Quality products of this type is characterized Germany's Knauf.Example floor drywall brand - heavy-duty slabs Knauf Bodenplatte.
Fireproof plasterboard contains a reinforcing additive - glass fiber, which increases the resistance of plasterboard fire and prevent the possibility of fire and destruction of the material at high temperatures because the heat-resistant type of drywall can be used as passive protection against fire.Fireproof plasterboard used at sites with strict fire safety requirements, as well as in crowded places (stadiums, shopping and entertainment centers, railway stations).Colour - red.
Moisture resistant gypsum board with increased resistance to an open flame.Today, the release of this type of material involved, only a few manufacturers (eg Knauf).
Marking: GKLVOPhoto 3 - From the wall drywall can produce false wall or partition of any type up to 10 m
addition to the basic types of drywall, allocate a few varieties.These include:
- restoration sheetrock - drywall smaller thickness for the cladding of old drywall constructions and wood, easy to bend, whereby it can be used when the shaped elements;
- laminated (vinyl) drywall - a normal sheet of any type of plasterboard, industrial method for coating PVC film, whereby the sheets are immediately ready for installation and finishing (however, such coverage is bad breath because of the film coating);
- reinforced plasterboard - plasterboard with fiberglass additives;
- acoustic perforated gypsum board - a special sound-insulating material for finishing the lecture halls, cinemas, recording studios, etc. Similar premises, require additional insulation;
- drywall arched - Thin-layer sheet plaster, often having no more than 6.5 mm in thickness, due to this material is flexible enough of it to carry out a curved elements such as a circle arch shaped ceiling cladding elements, etc .;
IMPORTANT!Not bad bends and drywall on one side of the perforated special spiked roller.
- gipsovolokno or GVL - the same drywall, however, without cardboard paneling, plaster reinforced by the use of fluff pulp and paper processing aids, makingGVL more durable material than the GCR (instead of prefabricated plasterboard subfloors and walls perform better because of the material);
- cam boards - gypsum for the production of this material is further subjected to calcination, which gives additional strength to the material (of the plates may be constructed without interior walls and preparing to start to finish).
size sheet of drywall
standard sheet of drywall should be rectangular and have the following dimensions:
- sheet length - from 2 000 to 4000 mm;
- sheet width - from 600 to 1200 mm;
- sheet thickness - from 6.0 to 12.5 mm.
for each application sheet characterized by their standards: for example, a thin arched drywall often produce a 1 200/2 500/6 mm or 1 200/3 000/6 mm.Waterproof sheet often has parameters 1 200/2 500 / 12.5 mm (at least - with a thickness of 9 mm).
As for the length of the sheet, the step change in the size of 500 mm 2000 mm, 2500 mm, 3000 mm, etc.Sheet length of 3 meters - one of the most sought after, becauseTechnical recommendations to sew up the wall plasterboard should be full-length (height of ceilings in a typical apartment of 2,5-2,85 m).
standard sheet width of 1 200 mm. small-format sheet of drywall can also be found on sale, but the volume of production of the drywall noticeably smaller.
thickness drywall used in housing construction, as stated above, is 6,5 mm to 12.5 mm.The thickness of the sheet varies depending on the intended use of the material.
For example, the minimum thickness of 6 mm plasterboard is used only in sheets of drywall to further arch the possibility of bending the sheet.
Wall drywall has a thickness of 12.5 mm plasterboard ceiling - 9.5 mm (12.5 mm sometimes with mandatory increase in the frequency profile settings), and water-resistant drywall GKLO - 12.5 mm.
When working with the material, it is important to take into account the weight: according to it one way or another to perform mounting frame members, too - choose fastening tools, etc.
According to generally accepted standards:
- weight of 1 m²drywall thickness of 6.5 mm is about 5 kg;
- weight of 1 m² of plasterboard thickness of 9.5 mm - about 7.5 kg;
- weight of 1 m² of plasterboard 12.5 mm thick - about 9.5 kg.
There are several types of the longitudinal edges of the sheet of drywall (scheme given below).
On sale you can find with the edges of the drywall type PC (VR, KR), PRO, the Criminal Code (AK), PLC (HRK), KS (VA), LC (RK) PLUK (HRAK), VARIO, KPOS (gipsovolokno release with the edges of the PC and FC).
PC (VR, KR) - longitudinal edge of the rectangular shape.Such plasterboard is used for "dry" installation, ie. E. Joints sheets after installation will not be laid.This type of edge is most often used in floor slabs, as well as standard sheets GVL.This sheet is suitable for the inner layers when performing multilayer cladding or for bundle of sheets of drywall in filling internal cavities of partitions (double drywall).
Criminal Code (lat. - AK) - longitudinal beveled edge.These edges are subject spackling using reinforcing tape sealing surface.Grouting joints on these pages perform in at least three stages - a process quite expensive over time.
PRO - modified beveled longitudinal edge slightly flattened shape (only found on sheets of drywall from the company Rigips).Connection joints only with reinforcing tape.
KS (VA) - analogue edge PRO companies to Lafarge Gips (Lafarge Gypsum), as well as the Polish branch of the company - Lafarge Nida Gips.Connection joints also produced only with reinforcing tape.
3K (RK) - slightly rounded longitudinal edge.This type of drywall joints can without sticking putty reinforcing tape.
PLC (HRK) - semicircular longitudinal edge.It reduces the complexity of the process of grouting.For this type of sheet used as a reinforcing tape is not required.Grouting filler high strength is performed in 2 layers.
PLUK (HRAK) - semicircular slightly beveled edge (edge alternative HRK).For the sealing of joints sealed with joint tape and reinforcing shpaklyuyut.This option edge gypsum board allows the use of technology for sealing joints AK-edge and grouting technology for plates with edges HRK.The versatility of this type of drywall largely determines its success in the market of building materials.
VARIO - one of the options semicircular beveled edge flat shape, let alone on the sheets of plasterboard Rigips.Connection sheets possible with putty reinforcing tape without it.
FC - rebated longitudinal edge.This type of edge is mainly found only on gypsum sheets.Reinforcing edges of FC plaster produced a paper tape (serpyanka).
in home repair is most often used sheets of plasterboard with feathered edges on the front side of the sheet - it is edge-type CC and PCS
IMPORTANT!When cutting boards inevitably appear cut off edge, while on the cut edge there is a protective layer of cardboard, because before processing the joints of sheets on the edges of a plane or a knife to make drywall chamfer.Next, use the putty, paste over the seam reinforcement tape.
Brand and manufacturer
by price / performance leader in a non-replaceable, holding to 70% of the plasterboard and accessories remains the German company Knauf.
also include foreign manufacturers can distinguish the French company Compagnie de Saint-Gobain SA (owns brands Rigips (RIGIPS), Giproc (gypsum plasterboard) and Nida Gips (Nida Gips) and Scandinavian producer GYPROC (gypsum plasterboard), the Polish and Belarusian brand NORGIPS- BELGIPS.
Plasterboard VOLMA, manufacturing Volgograd plaster factory of "plaster" is slightly cheaper, but on the technical characteristics of the material is not inferior to the market leader.
Among domestic manufacturers can also select OAO "Sverdlovsk Plant gypsum products" (Industry Group GIFAS (Gifas)). The most demanded product - gypsum plasterboard standard sizes (2 500/1 200 / 9.5 mm or 2 500/1 200 / 12.5 mm).

drywall What is better?
Judge for yourself on the basis of the required parameters listed at the beginning of the material.In terms of production, a broader selection, price and quality of the materials remains the leader Knauf.While other manufacturers are also responsible mentioned in the production of such products.
What to choose, plasterboard or OSB (OSB, particle board), which is better for the floor - a sheet of drywall or plywood or paneling - FCL and its variants or wall paneling, should decidedepends on a situation.For facade drywall, for example, without lining is not used because of fear of the material before the abundant moisture. On sale is a special plasterboard for roughing front facing (this material, too, "color", his marker - blue cardboard) .So, when it comes to choosing the material for the exterior, lining better.Speaking of the deck floor, it is best to choose a dry floor with sheets of drywall, plywood than dub under linoleum flooring or carpet.If we talk about the work of the wall, the drywall OSB much cheaper (by the way, both materials have dostoyano replacement - magnesite stove LSU).
