Popular about drywall

A drywall composite sheet is a three-layer composite material consisting of a layer of G-4 gypsum glued on the outside with strong cardboard.
Available in the form of plasterboard sheets of various types: conventional( GKL), fireproof( GKLO), moisture resistant( GKLV), moisture resistant and fireproof( GKVVO).
It is produced for rooms of ordinary and with high humidity.
Differ by the color scheme: gray-colored plasterboard for ordinary premises, plasterboard for wet rooms has a green color, fireproof plasterboard is painted in pink.
The Knauf gypsum plasterboard sheet is reinforced with glass wool to increase strength.

Characteristics GKL
GKL is widely used in the manufacture of suspended ceilings, internal partitions, for wall cladding.
The material is easy to use and does not require special skills and tools.

Standard dimensions GKL:
Sheet length 2,5 m;
Width of 1.2 m;
Thickness 12,5 mm.
The weight of the standard sheet does not exceed 30 kg.
For suspended ceilings, sheets of thickness not exceeding 9.5 mm are used, the weight of which does not exceed 25 kg.

The main advantages and disadvantages of the

material The low weight of gypsum boards allows them to be used in old houses without creating excessive load on the floors.
Drywall has increased strength. Each point attachment is capable of withstanding loads up to 12 kg.
The material does not require the use of solutions based on cement and water, which reduces the formation of debris, allows you to perform a "dry" assembly.
Partitions made of drywall are lighter and cheaper than brick, block, tile partitions.
GKL is widely used for the manufacture of arched constructions.
Plasterboard sheets do not smell, they are not electrically conductive, absorb excess moisture and secrete it in dry air indoors, can "breathe".
With gypsum boards, ideal surfaces are created that do not require additional alignment.
With the help of notches from sheets it is possible to obtain various curvilinear forms, to make columns.

The main drawback of gypsum boards, reduces the useful space of the room due to the installation of the frame.

Drywall sheets are used for the manufacture of false ceilings, the design of curvilinear surfaces, when zoning space.

The Russian construction market offers a large selection of gypsum boards from various manufacturers.
The lion's share of the market is occupied by the products of Knauf-Gyps and Gyproc. The Russian firm Knauf-Gips is a subsidiary of the German firm Knauf, and Gyproc from England.
Gyproc grade gypsum cardboard is more expensive than its competitor, as it is produced in the EU countries.
The material under the Gyproc brand is mounted on the metal profile of the Russian manufacturer "Alumasvet".To seal the joints it is recommended to use the material Rigips( England).

Knauf-gipsokarton mounted on a metal profile, developed by specialists of the firm Knauf.

Moisture resistant sheets are marked with letters GKLV( gypsum plasterboard moisture-proof) and are painted in greenish color.

Tip 1
To ensure quality work when installing gypsum board, it is recommended to use the accompanying materials specified by the manufacturers of GKL.

About qualifications and tools
It is not necessary to have experience and skills in working with plasterboard. It is important to have diligence, perseverance, perseverance.

Tools can not do without a puncher, a screwdriver, a plumb, a rule or a building level, metal scissors. You will also need a pencil, a hammer and a knife.

Of the accompanying materials you will need a metal galvanized profile, screws, dowel-nails, drills.

Assembling of walls, partitions

It's easiest to get acquainted with gypsum plasterboard with wall alignment. This type of work can be done independently, without involving assistants.
The most important stage, the installation of the frame from the galvanized profile. For this we will use the technology of Knauf.
The system is a metal frame made of galvanized profile, which is covered with sheets of gypsum board.

A few words about the

profile The "PS" rack profile is used, which resembles a channel section. Performs the function of vertical racks. The profile size is 28 × 27 mm. The imported marking of the rack profile has the CW index.

The "PN" profile profile of a similar cross-sectional shape serves as a guide rail for the "PS" profile and bridges between the rack profiles. The dimensions of the profile are 60 × 27 mm. Marking of the Western analog CD.
Corner profile "PU" provides fastening of external corner joints of plasterboard sheets.
The standard length of the profile is 3.0 and 6.0 m.

For the installation of the frame on the wall, the marking, drilling holes and dowels are required. The hole drilling step is selected from 0.4. .. 0.6 m.
The marking is applied depending on the dimensions of the applied gypsum boards.
Sheets should be placed in the middle of the frame profile.

Before attaching the sheets, be sure to install the required communications: electricity, heating, water, sewage, etc.

Begin installation of gypsum boards on walls without openings.
Sheets are recommended to be installed in staggered order, fastened around the perimeter and in the center.
Fasten the sheets with self-tapping screws, screwed strictly at right angles, withstanding the distance from the ends of the sheet to 10. .. 15 mm. In this case, the heads are necessarily heated by 1 mm.

As heat or sound insulation it is recommended to use glass wool, cork, isover, foam, laying between the supporting frame.

Tip 2
When installing drywall on walls with apertures, follow the rule: the joints of the sheets are mounted at a distance of at least 200. .. 300 mm from all the corners of the opening.

Suspended ceiling

Installation of a false ceiling is carried out with the assistant and consists of several stages:

• The ceiling level marking is made;
• Apply a horizontal line from the top of the ceiling along the entire perimeter of the room;
• On the horizontal line dowel-nails with a step of 0.5. .. 0.6 m fixed guide;
• In the slots of the guide, the ceiling profiles are cut, cut to size;
• It is recommended to maintain the distance between the profile axes: for a moisture resistant gypsum board 0,4 m, for an ordinary 0,6 m;
• The profiles are additionally fastened with suspensions with a fixing pitch of 0.5. .. 0.6 m.

To install the ceiling, see the video in more detail. Online calculator calculates not only the number of necessary sheets of plasterboard.

Tip 3
For greater stiffness of the ceiling frame between the longitudinal profiles, transverse inserts are installed using devices called "crabs".

To start facing the ceiling with sheets of plasterboard with subsequent finishing is only after conducting electrical and other works.

Conclusion:
- the main advantage of drywall is that if any part of the product fails, the replacement or repair of it can be easily done by hand.
