Many people mistakenly believe that the drywall in our country appeared in the early 90s XXveka, when the western gates became available and "poured" into the Russian market.Few people know that invented and patented plasterboard was in the XIX century, and large-scale industrial production has been established in 1917.Skeptics may argue that in the Soviet times nothing was known about the drywall, but hard facts tell a different story - this material has been successfully used by Soviet builders, however, it was called differently - drywall.He was not available to all and is not used in civil engineering, and therefore such an erroneous judgment.

But now everything has changed and drywall can buy one, it is in any hardware store.Not only is it attached to the entire range of components: profiles, connectors, fasteners, materials for sealing joints and more.But the main thing is that in the public domain are all technologies for work with plasterboard, the producers did not hide it.And not necessarily refer to the "super" in the art.Maybe a better understanding of yourself and make sure that this, in principle, nothing complicated and there.The main thing - to follow the guidelines, they are based on many decades of experience.But let's all in order.

How is drywall?

In the name of this unique building material hidden its structure.The basis of this building material is gypsum rectangular canvas size, which papered on all sides linerboard.

Gypsum - a naturally occurring mineral that has a number of unique and useful qualities:

  • gypsum ph level is very close to the human body.
  • products manufacturing gypsum-based does not harm the environment.
  • Gypsum is non-combustible material.
  • Plaster products help maintain a normal level of moisture, as they say in life, this material is able to "breathe".

main disadvantages of gypsum, which limits the use of materials based on it - it's the lack of moisture, and brittleness.Therefore, the standard plasterboard not use outdoors and in areas with high humidity, use only the leaves that have a special marking.

Types drywall

Plasterboard sheets, depending on the point of use and the availability of the necessary properties are different nomenclature.On what are plasterboard, described in the following table.At the same time an example of the nomenclature of the leading manufacturer of building materials - the world famous company Knauf.

Image Name cardboard color marking color Scope
GCR Plasterboard normal ( GCR ) Grey Blue for interior decoration with a normal and dry humidity conditions
GCR waterproof Plasterboard ( gypsum plasterboard ) Green Blue sheets are low (less than 10%) water absorption.They are used in areas with dry, normal and wet modes vladzhnym humidity
GCR Plasterboard with increased resistance to open flame ( GKLO ) gray or pink Red has a greater resistance to fire.They are used in fire-proof rooms
GCR waterproof Plasterboard with increased resistance to open flame ( GKLVO ) Green Red Combines properties of gypsum plasterboard and GKLO.It is used in fire humid

From the table it can be concluded that the use of certain gypsum board determines the moisture conditions in the room, as well as the level of fire danger.On what are humidity conditions of buildings, depending on the outside temperature is shown in the following table.

Knauf's engineers depending on the destination premises developed recommendations for the use of different types of gypsum board.

Recommendations for the use of GCR

Directions GCR

Plasterboard sheets are rectangular plates, which have different sizes of thickness, width and length.Main geometric dimensions, as well as the weight of 1 m2 of the sheet are shown in the following table.

Standard sizes of gypsum boards

Sizes gypsum boards

most often found on sale gypsum boards with 2500 mm long and 1200 mm wide.The rest of the sizes are usually made by the manufacturer on request.In addition to the geometric dimensions of gypsum boards are another important indicator - the form side edge.If the end edges are simply cut at right angle with the sheet bare gypsum core, the side edges for ease of joint devices may have a different profile, and they are pasted over cardboard.Types edges of drywall sheets (GCR) are shown in the table.

Image edge Type Designation Application
PC Straight edge PC / VR is used in two-layer constructions of plasterboardthat do not require sealing of joints of the lower layer
Criminal edge drop Criminal / AK required caulking GCR reinforcing tape and putty-type "Knauf Fugen»
PLC semicircular from the fronthand edge PLC / HRK Closing seam without reinforcing tape sealer such as "Knauf Uniflot»
PLUK semicircular and thinned from the front edge PLUK / HRAK Closing seam sealer "Knauf Fugen »with reinforcing tape, and" Knauf Uniflot "- without reinforcing tape
ZK rounded edges LC / RK Installation GCR followed by plastering

ceiling finishes andwall structures often finds application with GCR and semicircular thinned edge (PLUK), thereby reducing the production chain finishing, and it speeds up the process and significantly reduces the cost of it.

profiles and fasteners for plasterboard systems

natural that in itself is very rare plasterboard attached directly to the walls, and even more so to such critical structures as ceiling.For fixing frames going and have them special fasteners attached sheets of drywall.At first glance it may seem that the construction of plasterboard structures including a huge range of accessories and fasteners, but in fact it's much easier.Consider what profiles are used for arranging skeletons of two-level ceilings.

Image name, designation, Russian / English Description and purpose
0 profile guide ceiling PN 28 * 27 / UD 28 * 27 is made of galvanized steel with thickness 0,4, 0.5 or 0.6 mm.The standard length of 3000 or 4000 mm.Designed for use with the profile PP 60 * 27 / CD 60 * 27 for the arrangement of metal ceiling frames and wall cladding
1 profile ceiling PP 60 * 27 / CD 60 * 27 profile ceiling is the basis for the formation of metalframe from the ceiling plasterboard.It can be used for lining the walls of the FCL.Available in 0,4,0,6 m thick and a standard length of 3000 mm and 4000
2 profile rack guide PN 50 * 40, 75 * 40, 100, 40 / UW 50 * 40, 75 * 40, 100* 40 is made of galvanized steel with thickness of 0.4, 0.5, 0.6 mm.The standard length of 3000 or 4000 mm.Used together with profiles of PS / CW appropriate dimensions in the manufacture of the frame walls, but can be used in some very important places false ceiling construction (mainly Mon 50 * 40 / UW 50 * 40)
3 profile rack SS 50 *50, 75 * 50, 100 * 50 / CW 50 * 50, 75 * 50, 100 * 50 base to form partitions with the appropriate PN-profiles, but can be used in ceiling frames (PS / CW 50 * 50)

Plasterboard ceilings can be fitted in areas where they will be affected by high humidity or corrosive chemicals.That's why the profiles are made of galvanized steel, which is less susceptible to corrosion processes.Best to choose a thickness of 0.6 mm, as these provide the best profiles rigidity.Allowed application profiles made of galvanized steel sheet of 0.4 mm or 0.5, but only in those places where it is required, for example, to make short jumpers and other auxiliary elements.Bearing roof elements should be made only 0.6 mm profile.The length of the profile (3000 or 4000 mm) is selected based on the geometry of the room.The main rule - where possible it is necessary to use whole pieces of the profile.

Manufacturers of gypsum boards and their components is further possible to use as carrier and support elements wooden ceiling bars section 50 * 30mm or 50 * 50 mm.In this case, you must choose a softwood with a moisture content of not more than 12%, with all the bars before installation must first be treated with antiseptics and flame retardants.But creating complex ceilings, features include curved elements, it is best to use metal profiles for the following reasons:

  • metal has corrosion protection, does not require additional treatment.
  • Metal profiles easily handled tool available, using them to easily create any, even the most complex construction of multi-level ceiling.
  • Manufacturers plasterboard systems developed by different technical documentation for installation of structures with a detailed explanation of each step and the drawings.All of this information is publicly available.
  • Metal profiles are available in any store building materials and sold at a reasonable price.

addition to profiles of plasterboard systems use other elements for mounting and mounting skeletons for building structures.These elements there are so many, but we will consider only that which concerns the two-level ceiling of plasterboard in the following table.
