For a certain type of work it is necessary to select suitable look drywall. The types of this material are distinguished by properties and purpose.
Regular drywall This sheet consists of thick cardboard, which serves as the surface of the material, and gypsum dough. It is used for finishing rooms with normal humidity conditions. It should be noted such advantages of the material as efficiency, relatively low weight, ease of use.
moisture-resistant gypsum board (usually has green color)
It’s easy to guess that moisture-resistant sheets are used in wet areas, for example in the bathroom or kitchen. GKLV contains additives that reduce moisture absorption , do not delaminate and do not lose their shape. This type of drywall is resistant to mold and mildew. When choosing finishing materials, e.g. country house, choose moisture-resistant drywall, since humidity is country house higher than in a city apartment.
Sometimes when finishing a bathroom it is better not to use drywall at all. If a family has four or more people, each of whom takes a bath every day, it is better to refuse to use even moisture-resistant plasterboards. To decorate rooms where the humidity is off the charts, it is necessary to use more moisture-resistant materials.
Fire-resistant plasterboard - this material is excellent for cladding utility and non-residential summer premises and constructing partitions. GKLO provide the necessary fire safety and can be used near fireplaces and stoves.
This type of drywall has both the properties of fire-resistant and moisture-resistant sheets.
In addition to the listed types, they also produce a special repair gypsum board, which is used to correct minor damage in a ready-made plasterboard structure.
Wall plasterboard is used for finishing walls and ceilings; arched plasterboard is best suited for creating stylish and all kinds of curved openings.
It is advisable to use solid sheets for cladding walls and ceilings. Their number must be calculated in advance. Standard size plasterboard sheet is 2500 by 1200 mm. The sheet area is exactly three square meters. There are also non-standard sizes plasterboard: length from 1500 to 4000 mm, width from 600 to 1500 mm, thickness from 6.5 to 24 mm, so be sure to check the size with the seller before purchasing. Whole gypsum boards can only be used for cladding large areas, and when renovating a small apartment it will have to be cut to the required size.
Below are tables of the main technical parameters Knauf plasterboard, which you need to know when purchasing it.
Not so long ago, very few people knew about drywall. When renovating rooms, they used plasters and gypsum, which made it possible to decorate them with greater expressiveness. Our designers are surprised at how in the past specialists could do finishing without using (gypsum plasterboard) plasterboard sheets. After all, it is this material that helps realize the most daring projects and fanciful fantasies.
With the help of drywall it is possible to create multi-level ceilings with backlight, also called labyrinthine. Can be created in any shape and size. With the invention of drywall, it became possible to create countless unique interior compositions.
Drywall (the usual type) is very popular and comes in the form of sheets. The basis plasterboard sheet consists of plaster, which is located between two sheets of cardboard.
To give plasterboard sheets certain properties, add various substances, improving its strength, moisture resistance and other properties.
On sale there are plasterboard sheets with identical properties and characteristics, but at the same time different colors. This must be kept in mind when purchasing gypsum boards. There are no strict labeling standards, which creates certain difficulties for the buyer when choosing the required material. When choosing drywall, you should not focus only on the color of the Knauf gypsum board sheets. The technical characteristics of the purchased product should be decisive.
Drywall is available in four types, depending on its properties and application:
Drywall is used for the device suspended ceilings, cladding and creating niches in walls, is used to create partitions between rooms with humidity within normal limits.
Typically, drywall is used as a frame for the subsequent application of various finishing materials - paint, tiles, wallpaper, etc. The result is a fairly solid and flexible base.
The cardboard with which the core of the plasterboard sheet is covered on both sides has flat surface and high density. It is used for finishing because it is hard and flexible, and also has the ability to “breathe”, that is, the material absorbs excess moisture, and when the air becomes drier, it gives it back.
Thanks to this ability, it is much easier to breathe in rooms where drywall is used. In addition, drywall has the same acidity as human skin. As a result, a microclimate favorable for humans is naturally created in the room.
Special processing of the only flammable gypsum board material - cardboard - makes this one as a whole. Under the influence of open fire, sheets of drywall only become charred, and the moisture contained in the depths of the sheet prevents the movement of the flame.
GKL "Knauf" (regular plasterboard sheet 1 and other types) is an environmentally friendly building material, since it does not have any negative impact on the objects surrounding it, which is confirmed in quality certificates. In addition, gypsum board is also an excellent soundproofing material.
Besides interior decoration premises, flat sheets Drywall is widely used to level out uneven walls, which is why gypsum board is also called dry plaster. When working with gypsum plasterboard sheets, processes involving the use of water are eliminated, which simplifies the work and reduces its cost, making plasterboard even more attractive for both professionals and beginners in the field of construction and repair.
The lack of debris also makes working with drywall much easier. Not to mention the fact that finishing work carried out using this material can significantly save money and time. In our country, the Knauf gypsum board is most often used, the technical characteristics of which distinguish it favorably from a number of similar ones from other manufacturers.
In addition to gypsum plasterboard (standard plasterboard sheets), waterproof and fire-resistant sheets are produced. Moisture-resistant plasterboard sheets are used mainly in bathrooms and kitchens. When finishing communication shafts and air ducts, fire-resistant Knauf gypsum boards are used, the technical characteristics of which easily allow this.
In the manufacture of drywall, burnt gypsum is also specially used, which ultimately makes it possible to obtain tongue-and-groove slabs. They are highly durable and therefore are often used in interior partitions. Such slabs do not require any preliminary preparation before finishing. Partitions are made one-, two- and three-layer. Tongue-and-groove slabs are especially relevant in areas with unstable seismic conditions. Cables, dust removal systems, heating or plumbing communication systems are laid in the cavities located inside such slabs.
An important property of drywall is its ability to take on a rounded shape, which makes its scope wide. The desired shape is obtained quite simply: you need to moisten the plasterboard board, wait until it is properly moistened, and then bend it as needed in a particular case. After this, the drywall is dried. It is noteworthy that after hardening, the technical characteristics of Knauf sheets completely return to the original ones.
There are ceiling, wall and arched plasterboards. The fact that the sheets of this material are flat makes it easy to correct uneven walls or ceilings. In this case, there is no need for further plastering of surfaces.
The geometric dimensions of the Knauf gypsum boards are very diverse. Length - from 2000 cm to 4000 cm (in increments of 50) and width - from 600 cm to 1200 cm. Thickness is: 0.65, 0.8, 0.95, 1.25, 1.4, 1.6, 1.8, 2.0, 2.4 cm - depending on purpose of the material.
The standard one is 2500 by 1200 cm. The area of such a sheet is equal to three square meters. They are as follows in thickness:
Walls are finished with plasterboard sheets, and partitions are made from them. Ceiling is used to create ceilings, and with the help of an arched ceiling they create exquisite interior arches and various curved openings.
Quantity required material calculated in advance, taking into account the fact that when finishing it is advisable to use whole sheets.
In addition to creating regular, hanging and multi-level ceilings, attached to various frames, produced by Knauf("Knauf") gypsum board sheet is used when constructing the underlying layer of floors.
Another important property GCR - its ability to easily bend and retain its shape. Due to this, drywall is widely used in creating decorative elements, turning from rectangular sheets into domes, columns or vaults. Designers have the opportunity to make their wildest fantasies come true.
Gypsum fiber sheets (GVL) are another type of Knauf gypsum board, the technical characteristics of which indicate the highest resistance to fire. It does not use cardboard, and the sheet core is lined with fluffed waste paper. Additional additives with which the material is impregnated also provide fire resistance.
Plasterboard sheets can be easily cut with a regular knife (preferably sharp) and can be sawn well, in addition to being flexible. Using special tools, you can cut out parts of any size and shape, as well as make the necessary holes in them. The fact that marking and cutting holes, for example, for sockets and switches, is possible outside the installation site, allows us to significantly reduce the time required for work.
If we compare finishing with plasterboard with finishing with plaster and putty, it is obvious that in the first case the work is completed twice as fast. At high quality labor costs are reduced threefold in the manufacture of interior partitions if Knauf plasterboard is used. Knauf gypsum plasterboard sheets are mounted using related materials such as screws various sizes, gypsum glue, tapes for sealing, etc.
Knauf is the world's largest company producing a variety of finishing materials for both interior and exterior exterior finishing, including gypsum boards. The characteristics of gypsum plasterboard of this brand are the best, which is confirmed by many years of experience in use in construction and repair.
In 30 countries in the USA, Asia, Europe and South America more than 120 factories belonging to the Knauf group are located.
The topic of our article today is “Knauf drywall size” and this is not without reason. Drywall from Knauf takes a leading position in construction market our country. Therefore, many master builders will be interested in knowing its technical characteristics and scope of application.
Knauf plasterboard is most often used in repairs and construction as finishing material:
What are Knauf plasterboard sheets? They are rectangular planes that consist of gypsum and special reinforcing additives. These planes are lined along the contour with special cardboard on both sides, which is very stable. The core contains a binder of G4 grade gypsum, manufactured in accordance with GOST 125-79.
Plasterboard sheets are produced in accordance with GOST 6266-97, thanks to which they fully meet the requirements of DIN 18 180, which is a German standard. The reliability and manufacturability of plasterboard is ensured by a semicircular thinned edge, which is used at joints.
The adhesion of the core to the facing cardboard occurs using special adhesive additives. Cardboard acts as a reinforcing frame, which is also a pretty good basis for subsequent finishing, be it decorative plaster, tiles, paint or wallpaper.
The dimensions of Knauf plasterboard sheets are most often given in millimeters:
Quite often, plasterboard sheets are used, the size of which is 2500x1200x12.5 mm. A sheet having these dimensions has an area of approximately 3 m2 and a weight of approximately 29 kg. Drywall is packaged in packs of fifty pieces. One such package is enough to cover an area of 150 m2.
Each sheet of Knauf drywall has special designations:
Depending on where plasterboard sheets will be used, they can be divided into arched, ceiling and wall. Walls and ceilings finished with plasterboard become absolutely smooth.
Important advantages of plasterboard are its fire safety and environmental friendliness.
In all rooms that are finished with such slabs consisting of cardboard and gypsum, a rather favorable atmosphere for human life develops.
1. Sheets for wall decoration, having a thickness of 12.5 mm, are most often used for finishing walls and creating partitions. Thanks to the use of plasterboard, the use of “dry construction” technology becomes possible.
2. Sheets intended for finishing the ceiling have a thickness of 9.5 mm. They are used to make suspended ceilings. In principle, it is suitable for this purpose wall plasterboard, but it weighs more and costs more.
3. For the construction of arches or any other structures that require changing the shape, arched plasterboard is used, which has a thickness of 6.5 mm. Thanks to this thickness, you can create a variety of elements that have a round or simply curved shape.
Depending on the area of application, properties and technical characteristics, plasterboard can be different types. At the same time, the size of Knauf drywall can also be different. Drywall can be ordinary, moisture-fire-resistant, fire-resistant and moisture-resistant.
1. Regular drywall is usually beige in color, and the lettering on it is blue. This type of plasterboard is used for cladding ceilings and walls, and also, using a metal profile, for the construction of partitions in rooms with normal level humidity.
This type of drywall can have the following parameters:
2. Moisture resistant sheets drywall are green and have blue lettering. This type of drywall is used in rooms with high humidity– in the bathroom, in the kitchen, and also as a base for ceramic tiles. In this type of drywall, both the core and the cardboard itself are treated with a composition that prevents moisture absorption, so you will not have problems with mold and mildew. Moisture resistant sheets are often between 2500mm and 4000mm long, 1200mm wide and 9.5mm to 15mm thick.
3. Fireproof plasterboard sheets are painted in beige color and red inscriptions. Most often this type is used in rooms with special fire safety requirements, and also in order to build attic spaces. It is necessary to pay attention to the fact that the core of such drywall has additional reinforcement, which includes at least 0.2% of the total weight of all fiberglass threads having a length of 3 to 30 mm. Thanks to this, it can maintain its integrity much longer in the event of a fire.
Sheets of such plasterboard can be from 2500 to 4000 mm long, 1200 mm wide and 12.5 and 15 mm thick. These sheets weigh from 10 to 16 kg.
4. Moisture- and fire-resistant plasterboard sheets are painted green and have red lettering. It has the properties of the two types described above. It is used in areas that may be exposed to high temperatures and moisture. The sheets are exactly the same dimensions as fireproof.
Depending on what characteristic properties has one or another drywall, it can be classified into one of the groups:
After you have familiarized yourself with all existing species and the dimensions of Knauf drywall, which were described above, you can independently select the type of drywall that you need for finishing and compliance with fire safety and moisture protection rules.
Using one type of Knauf product, rationally and related materials purchase the same brand. One of the manufacturer’s concepts is material compatibility. That is, for example, plasterboard Knauf and fasteners of the same brand fit together perfectly.
It is believed that about 70% of drywall sold in Russia is produced under this brand. Knauf has been a confident leader in its market for many years, and the company’s factories are widely represented in Russian territory.
Knauf is an international company based on the classic principles of a family business. The manufacturer adheres to these rather rare principles today, which certainly affects the quality of the product. This company is rightfully considered an authority in the world of corporations producing building materials.
There is no doubt that factories located in the CIS operate using exactly the same technology as in the West. The equipment at the factories is the most modern and advanced, and the quality standards are the same both for, for example, a plant located in Germany and for a Russian plant.
Construction sheet-gypsum boards of type A - this is the correct name for the gypsum boards familiar to everyone. This is a high-quality construction and finishing material that is used for cladding walls, constructing partitions, ceiling structures and products whose task is sound absorption and sound insulation.
Each Knauf sheet must contain the following information::
If we talk about technical characteristics, then Knauf sheet is a rectangular building element consisting of two layers of special cardboard with a gypsum layer and the addition of reinforcing inclusions. The side edges of the strip are folded with the edges of cardboard.
The core of such a sheet is gypsum binder under the designation G4 (GOST 125-79).
Knauf sheets have:
By the way, the technical characteristics of cardboard meet all the requirements for using this material in residential premises.
GKL sizes:
A standard plasterboard sheet has dimensions of 2500 x 1200 x 12.5. A sheet with an area of 3 square meters weighs 29 kg. Drywall is packaged in bags, each containing 50 slabs. One package is definitely enough to cover 150 square meters.
Some craftsmen alter these sizes to suit themselves, but choose right size there is plenty, so such a need may not arise. Such parametric characteristics are very convenient for the buyer to choose.
This is perforated plasterboard. The name speaks for itself - perforated boards are used for sound insulation and noise absorption. This is a sheet whose edges are cut off and a sound-absorbing layer is glued to the back side.
At the same time, the sound absorption parameters of the slabs may be different (again, there are plenty to choose from). And the design of plasterboard boards varies; they can be white or black.
Complete Knauf tig systems are another great discovery and invention of this construction brand. The essence of the system is that repairs occur without so-called wet processes. That is, no liquid masonry or use of plaster. For many craftsmen, this is a compelling argument in favor of purchasing products from this particular manufacturer.
The kit includes:
That is, a list of items that are included in complete system, will be impressive. There are the plates themselves, and profiles, and extensions, and connectors. Included in the complete system are hangers, screws, anchor elements, and dowels. It is noteworthy that you will also not have to spend money on reinforcing tape, putty and primer - everything is included in the kit.
Gypsum plasterboard KNAUF sheet (GKL) is a rectangular element that consists of two layers of special cardboard with a layer of gypsum dough with reinforcing additives, while the side edges of the strip are folded with the edges of the cardboard (front layer).
KNAUF plasterboard sheets (GKL) are produced with various types edges The main ones are: straight (SK), thinned (UK), semicircular and thinned with front side(PLOOK).
To form the core, gypsum binder grade G4 is used according to GOST 125-79.
Another important component plasterboard KNAUF sheet(GKL) is a facing cardboard, the adhesion of which to the core is ensured through the use of adhesive additives. Cardboard plays the role of both a reinforcing frame and an excellent basis for applying any finishing material (plaster, wallpaper, paint, ceramic tile and etc.). Due to its physical and hygienic properties, cardboard is ideal for residential premises.
KNAUF plasterboard sheets (GKL) are produced in accordance with GOST 6266-97 and meet German standards (DIN 18 180).
