Which is better - OSB or plasterboard: comparison of gypsum and particle boards

Are you choosing structural finishing materials and don’t know which is cheaper and better? I bring to your attention an overview of the characteristics of gypsum and particle boards, which are indispensable when performing home renovations. After reading the review, you can decide which of the listed materials is suitable and which is not.

Review of structural finishing materials

To the category of structural finishing materials include sheet gypsum and wood products, with which you can build dividing partitions, cover walls, ceilings, etc. with your own hands.

Illustrations	Description of construction materials
	Drywall. This environmentally friendly material consists of a gypsum plate covered with thick cardboard on both sides. Depending on the composition of the gypsum layer and the processing of the cardboard, gypsum fiber sheets (GVL), plasterboard sheets (GKL), etc. are distinguished.
	Oriented Strand Board (OSB or OSB). OSB board consists of medium- and large-sized chips, pressed in a resinous binder into rectangular sheets. There are three classes of OSB with differences in structure density and, as a consequence, strength.
	Particle board (chipboard). Chipboard is sheets pressed from small shavings and sawdust in a resinous binder. Due to the small chip size, ready product characterized high density and greater weight compared to OSB.
	Multilayer plywood sheets. This is the most environmentally friendly and visually attractive material of all the listed wood products. Plywood is made from natural wood veneer glued together with a resin-based binder. If the question is which is more profitable, plywood or drywall, then the latter option costs half as much.

Characteristics of gypsum sheets

The prices in the article are current in the summer of 2017.

Gypsum sheets on the market are presented in three standard sizes: 2000×1200 mm, 2500×1200 mm and 3000×1200 mm. The material is also divided into ordinary (GKL), moisture-resistant (GKLV) and fire-resistant plasterboard (GKLO).

Illustrations	Application
	Laying dry screed. Special gypsum sheets with a thickness of 15-20 mm are laid, as in the photo, on expanded clay backfill. This technology was developed by Knauf and is used in many countries around the world when arranging residential premises. Price: from 300 rub. per sheet 1200×600 mm.
	Cladding of walls and slopes. When finishing walls and assembling partitions, the thickest sheets are used: 12.5 mm. Sheathing is carried out on load-bearing frame, which traditionally contains heat and sound insulation. Price: from 230 rub. per sheet 2500×1200 mm.
	Ceiling cladding. For such purposes, a plasterboard sheet with a thickness of 9.5 mm is used. Installation is carried out on a suspended lathing. Price: from 250 rub. per sheet 2500×1200 mm.
	Arch trim. For such purposes, the most thin sheet with a thickness of 6.5 mm. The small thickness of the sheet is due to the fact that the strip of drywall has to be bent. Price: from 300 rub. per sheet 2500×1200 mm.
	Installation of partitions. For the construction of partitions in residential premises it is recommended to use tongue-and-groove slabs or drywall. In the case of plasterboard, installation is carried out on a frame; in the case of tongue-and-groove slabs, you can do without a frame.

The use of sheet plasterboard is possible only in the interior, subject to normal humidity and normal air temperature.

Characteristics of particle boards

There are several types of oriented strand boards on sale, of which laminated or varnished OSB-2 boards can be used for interior decoration. For construction external walls OSB-4 is used in frame houses and for laying floors. Recommended for finishing rooms with high humidity OSB boards-3. average price OSB-3: 200-300 rub. for 1m².

Illustrations	Application
	Floor covering. When laying a floor, tongue-and-groove particle board is used in much the same way as plasterboard is used when installing a dry screed. To connect the floor fragments, a fastening recess is made along their perimeter.
	Wall covering. For these purposes, only laminated OSB with a low degree of toxic substance emission are used. The use of such cladding is advisable in utility rooms and temporary residence facilities (cabins, resort houses, workshops, etc.).
	Floor covering. Using OSB, you can not only sheathe the ceiling, but also clad the ceiling in a frame house.
	Construction of partitions and load-bearing walls. Load-bearing walls OSB is sheathed in frame houses, and they are built according to the same principle interior partitions. The walls covered with OSB are covered with lining.

Comparing both materials

• Scope of application. Both plasterboard and particleboard products are used in a similar way, but OSB can be used for exterior cladding of a house, subject to subsequent finishing with DSP or similar mixtures.
• Compatibility with finishing materials. Both drywall and OSB can be painted and wallpapered only after preliminary puttying. Unlike preparing gypsum boards, puttying OSB is a more labor-intensive process.
• Environmental Safety. Drywall is environmentally friendly as it does not contain toxins or carcinogens. OSB contains resins that release phenol vapor into the environment. In order to reduce phenol emissions, the surface of particle boards is laminated, varnished or painted. That is, you can use gypsum plasterboard and OSB, but only with additional finishing.
• Moisture resistance. Both materials are not initially designed for contact with moist air. But the range of manufacturers includes gypsum and particle boards that are resistant to moisture.

Let's try to draw a conclusion. Both plaster and wood boards will find their buyer, since both materials are indispensable for correct use. If you choose a material for interior decoration, taking into account the pros and cons of drywall, I still recommend plasterboard. Why?

• Firstly, the price of drywall, even taking into account the purchase of related materials, is lower.
• Secondly, the instructions for working with gypsum plasterboard are simpler than using particle board.
• Thirdly, using gypsum plasterboard, you can create complex architectural forms, which, in principle, is impossible using OSB.

Let's sum it up

Now you know what construction materials ideal for covering walls, ceilings and for laying screeds in the interior. If you have any questions, I recommend watching the video in this article.

If you want to express gratitude, add a clarification or objection, or ask the author something - add a comment or say thank you!

Modern construction market offers various options for interior decoration. Drywall and OSB are very popular among the population. However, it is not yet clear which option will be better. Our article will help shed light and give a definite answer to this question.

Debriefing

To understand what would be better to use for interior decoration, OSB or plasterboard, you need to carry out comparative characteristics, which is only possible with a detailed examination of each material separately.

Tandem cardboard and plaster

Drywall is particularly popular today, as it has a number of advantages that its structure gives it. Plasterboard consists of three layers:

• core - it consists of gypsum and additional additives, which give the sheets certain properties;
• two layers of cardboard. They cover the core on both sides.

Plate structure

The composition of the material in percentage terms includes: 91.1% - gypsum, 5.78% - cardboard, and the rest - water. Thanks to this device, drywall has the following advantages:

• it is a completely environmentally friendly material;
• a light weight. The stove weighs relatively little so that one person can move it without any problems;
• easy installation;
• strength;
• durability;
• the board is an excellent basis for various finishing materials - paint, wallpaper, decorative stucco, ceramic tiles, artificial stone etc. Plasterboard walls and ceilings can be decorated in the most unimaginable ways;
• from it you can create the most various designs: suspended ceilings, wall cladding, formation of partitions, arches, niches and columns;
• safety. The material is completely safe for human health. Only when cutting it you need to cover your eyes and mouth so that dust does not get there;
• price. The material is available and costs less than some other types of finishing, especially if drywall is used to renovate the entire house.

With a material such as drywall, you can give your apartment a unique appearance, making it original and very beautiful. In addition, drywall has certain specific properties that are given to it by special core additives. Among the special properties of the material are the following:

• moisture resistance. Sheets with such properties can be installed in rooms where there is a humid microclimate. Such slabs are used in the renovation of attics, kitchens, bathrooms and toilets;

Moisture resistant sheets

• fire resistance. This type of slab is used in rooms with a dry microclimate, as well as where there are increased fire safety requirements. Thanks to special additives, such material can withstand exposure to open fire for about 40 minutes;

Fireproof sheets Fire and moisture resistant sheets

• fire and moisture resistance. There are sheets of plasterboard that can combine both fire resistance and moisture resistance. They are installed in rooms with dry and humid microclimates;

• ordinary. Such sheets are used for finishing walls and ceilings in rooms with a normal microclimate.

In general, drywall can be used in almost any room: bathroom, kitchen, living room, toilet, bedroom, etc. Balconies, loggias and attics are also finished with this material.

Let's talk about the shortcomings

Despite the huge number of advantages, plasterboard as a material used for interior decoration also has some disadvantages:

Note! Each individual situation has its own step-by-step instructions that will help you easily cope with the task of hanging heavy objects on plasterboard walls.

• deformation of the slabs when trying to fasten heavy objects to the walls;
• When cutting sheets into pieces, small construction debris appears. Therefore, all work on cutting plasterboard should be carried out with special safety glasses, and also cover your mouth with a mask;
• reducing room space by assembling the frame.

If desired, all these negative aspects of working with the material, in addition to reducing space, can be leveled out. To do this, you must strictly follow the appropriate step-by-step instructions.

Purpose of the material

Any of the above types of plasterboard sheets are used for the following types of work:

• leveling walls in the bathroom, kitchen, living room and other rooms. They are even suitable for finishing the attic;
• installation of complex ceiling structures;
• assembly of furniture of the parameters that are necessary;
• creation of shelves, niches and columns, both functional and decorative;
• creation of stands;
• installation of complex figured elements. They can be installed on walls or ceilings.

The material is excellent for finishing walls and ceilings in residential and non-residential premises. It is plasterboard that is most often used for finishing the attic, kitchen, loggia and bathroom.

Let's move on to the opponent - OSB

OSB structure

IN Lately There is a trend towards increasing popularity of OSB boards. Very often, such a slab comes in tandem with three-layer panels and insulation, which increases thermal insulation properties the entire structure. Oriented Strand Board (OSB) or Oriented Strand Board (OSB) is a multilayer sheet. Usually it consists of 3-4 layers. Its layers include the following materials:

• wood shavings. It can have a longitudinal or internal transverse orientation;
• various resins;
• boric acid;
• synthetic wax.

OSB consists of 95% sawdust, the remaining 5% comes from a small amount of impregnation, paraffins and glue. The properties of the slab directly depend on the type and quality of sawdust. Sometimes the top of the slab is additionally treated with wax to increase its moisture-resistant properties. This structure of the material determines its following advantages:

• availability;
• reliability;
• external resemblance to a tree. Great for wall decoration;
• high quality;
• low weight;
• high rate of fracture deformation.

In addition, the material has the following properties:

• relatively high strength. It is higher than that of chipboard;
• has some moisture-resistant properties;
• ease of processing;
• excellent sound absorption;
• high rigidity.

As you can see, OSB boards have quite good advantages, allowing them to be widely used for interior decoration.

Flaws

Sawdust for production

Among the disadvantages of OSB boards, the main place is occupied by the possibility of the material releasing toxic substances. Formaldehyde and toxic resins can be released here. During the production of OSB boards, large sawdust is used, which are connected to each other with glue during the process. The result is a solid slab. It is the presence of glue in OSB that is the reason that such a board can be toxic and release dangerous compounds into the air.

Note! Much less glue is needed to create OSB boards than with chipboard production. Therefore it is less toxic.

TO disadvantages of OSB can be attributed:

• low fire-resistant properties;
• low strength indicators. To increase it, two plates are installed;
• more difficult to install on walls. Installation is more labor-intensive compared to drywall;
• cutting creates a lot of construction waste;
• low vapor permeability properties.

This material is not very suitable for carrying out repair work in the kitchen, bathroom and attic.

Purpose of the material

OSB boards are used in the following situations:

• for external cladding while using some cladding coatings;
• continuous roof lathing;
• installation of subfloors;
• for the production of structural SIP panels;
• wall covering.

Wall decoration

In addition, the material is used for finishing and structural work. This material is practically not at all suitable for finishing walls in some rooms (as already mentioned - in the bathroom, kitchen, etc.).

Verdict

It is worth noting that the price of OSB board is approximately on the same level as drywall. Therefore, based on the price parameter, it is difficult to make a choice which is better - gypsum board or OSB. Therefore, the choice should be made based on other parameters. In terms of environmental friendliness and harmlessness, drywall wins. It contains only biological materials, and glue and resins are used to make OSB boards. Also, OSB board cannot withstand exposure to direct fire. As you can see, it’s already 2:0 in the GCL.

In general, having studied in detail the advantages and disadvantages of materials, we can conclude that it is still better to use drywall for renovations in the bathroom, kitchen, wall decoration for the attic and other rooms.

The choice should be based both on personal preference and on the merits of the material, as well as the location of its further installation: in the bathroom, kitchen, attic walls, etc.

Choosing between plasterboard and OSB boards

Among the huge range of finishing materials, plasterboard and oriented strand boards are deservedly popular. Both options have their strengths and weaknesses. And to figure out which is better, OSB or drywall, you need to familiarize yourself with them in more detail.

What is drywall, its pros and cons

Drywall can rightfully be called one of the most universal materials for interior decoration of the house. With its help, you can create perfectly smooth walls, make structures of any complexity in the form of arches, original niches, multi-level ceilings, pilasters, columns and much more.

This versatility of drywall is ensured due to its base, which is a natural material obtained by firing at a temperature of 1800 degrees - building gypsum.

In addition to gypsum, the filler may contain adhesive composition PVA, starch, fiberglass, etc.

The gypsum, ready for further processing, is placed between two layers of thick cardboard. For the manufacture of plasterboard sheet use cardboard with a density of 0.17 - 0.22 kg/m2.

So that this building material there was a securely protected edge, its edges curved around the ends. This technique allows you to protect the sheet during transportation or storage.

Pros of drywall:

• Naturalness of the material. No synthetic additives or toxic substances are used for its production, which allows you to obtain an environmentally friendly finish inside the house.
• Can be used in any room, but for use in places with high level humidity (for example, in the bathroom), it is recommended to choose moisture-resistant gypsum board
• Does not cause any difficulties during implementation installation work. The material lends itself well to any processing and is easily modified. This advantage of gypsum board allows you to create the most incredible designs and reliefs
• The ability to hide various communications in plasterboard niches, as well as uneven walls. Insulation material can be laid in the voids formed during the installation of drywall.
• High thermal and sound insulation qualities
• The ability to create a comfortable, controlled microclimate in a room finished with plasterboard that can absorb and release moisture
• GKL has a good fire safety rating
• Plasterboard structures lend themselves well to painting, plastering, tiling, and wallpapering.
• Possibility of quick and relatively simple repairs in case of cracks, dents, deformation, or through holes
• Availability of material

Disadvantages of plasterboard finishing:

• Moisture-resistant drywall, often used in bathtubs, cannot fully resist negative impact water. It is not recommended for use for finishing ceiling in multi-storey buildings where there is a high probability of flooding by neighbors above
• In rooms with high humidity levels, even with special surface treatment, it is not always possible to prevent the appearance of mold on gypsum boards. Only by installing waterproof materials during finishing can you achieve the desired result
• Low mechanical strength of the material, which suggests strengthening the future structure with the help of embedded elements during fastening lighting fixtures or in places where paintings, equipment, household items, etc. will be hung.
• Precision and accuracy when working with gypsum plasterboard; fastening must take into account the characteristics of the material
• The need for additional finishing (sealing seams, recesses)
• Availability of a dry room in case of storing sheets in reserve

In order to understand which is better - plasterboard or OSB board, it is recommended to study the strengths and weaknesses of the latter.

What are OSB boards, their pros and cons

Oriented strand boards (OSB, OSB, OSB) are made in the form of a multi-layer sheet texture from coniferous or hardwood chips made from non-commercial wood. The chips are glued together with a variety of resins under high pressure and high temperature. On outside The sheet shavings are laid out longitudinally, and on the inside - transversely, which makes the slabs especially durable.

Advantages of the material:

• Can be bent if necessary for interior wall decoration. Unlike plywood, it does not crack
• Moisture-resistant options can be used for external cladding gazebos, outbuildings. The OSP-3 and OSP-4 grades with a high level of resistance to moisture have proven themselves especially well.
• When fastening the material does not cause any difficulties, the screws are securely held in the structure of the canvas
• The slabs are easy to process, fastening them is quite simple, and you can cut them to size with a chainsaw
• Availability of material
• Wide choose finishing, you can use varnish and paint materials, plaster, etc.
• Long service life if attached according to technology. If the slab is treated with a fire-resistant compound, it can last up to 300 years.
• High degree of strength
• Does not shrink
• The material contains no harmful components
• If you cover the slab with high-quality varnish, the surface will be complete

Disadvantages of OSB boards:

• There are products from manufacturers that add glue with formaldehyde and other substances harmful to human health.

When purchasing a product, you need to pay attention to its quality and composition.

To answer the question “Which is better, plasterboard or OSB for interior decoration of a house?”, you need to compare these two types of material.

Comparison of gypsum board or OSB

To find out which is better, OSB or plasterboard on the walls for interior decoration, we will compare the following parameters:

• Scope of application. Both gypsum board and OSB can be actively used to create furniture (in the kitchen), ceilings and arched structures, curly elements. Using moisture-resistant options, you can cover the walls in the bathroom.
• Environmental friendliness. Two types of material high-quality manufacturing do not contain substances harmful to the human body.
• Moisture resistance. GCR is more susceptible to the development of mold on it than its opponent. If we consider what is better to mount on the bathroom wall, plasterboard or OSB, then it is better to give preference to universal products - OSB-3 with a high level of moisture resistance and susceptibility to mechanical loads.
• Strength. This is where oriented strand boards win.
• Difficult to process. Both materials are easy to process, and their load capacity is relatively high.
• Heat and sound insulation qualities. If there is too much loud sounds a panel made of building gypsum will vibrate; to eliminate this negative point, you will need to finish the surface with several layers of cladding and fill the voids with fiberglass or mineral wool. But today the manufacturer has presented a unique product - acoustic plasterboard with excellent soundproofing properties. It attaches very simply. With this approach, both materials will have almost the same effect.
• Difficulty at work. If you figure out what is better to mount, OSB or drywall, then there is not much difference. They attach equally well and do not cause any difficulties even for a home craftsman.

In which cases is it better to use OSB, and in which plasterboard?

For finishing roofs, for covering floors, for exterior work, for creating frame-panel construction, it is recommended to use oriented strand boards with high technical characteristics.

For interior wall decoration and execution original designs choose a material based on building gypsum.

Having found out which is better than OSB or plasterboard, you can begin planning renovations in a specific room. The main thing is to choose a product from a trusted manufacturer and install it reliably and efficiently, following construction technology. If moisture resistant drywall mounted on OSB, you can get a surface with a long service life and quite strong.

OSB boards are a real find for construction, their types and features

The term “OSB boards” or “oriented strand boards” is commonly used to describe a new generation of building material obtained by treating wood chips with waterproof resins under high temperature and pressure conditions.

What are oriented strand boards

OSB boards consist of three layers of “wood wool” and wood chips coniferous species, having a length of 6-9 cm, located in opposite directions. That is, in the two outer layers the chips are in a parallel position relative to each other, and in the inner part of the slab they are in a vertical position, located perpendicular to the other layers. Due to this structure, the material has high mechanical strength and flexibility.

Impregnation with waterproof wax and resins and pressing under high temperatures and pressure allows OSB boards to acquire a uniform structure over the entire width and length and prevents the formation of voids and cracks in them.

Thus, the output is a high-quality material made from pure wood, without small debris, and with high technical and physical characteristics. It does not rot, is not affected by fungi and bacteria and, unlike natural wood, is absolutely not flammable.

That is, at its core, OSB can be called “improved wood”, having all of it best qualities, as well as greater strength and elasticity, and free from such disadvantages as the presence of knots and changes in the direction of fibers when natural growth tree.

Thus, if you evaluate this material using a standard scale with a five-point gradation, it can be assigned “fives” for practicality, ease of use and environmental friendliness.

This is what the OSB board looks like in the photo

Types of OSB boards and their differences

According to the degree of moisture resistance and strength, OSB boards are divided into several main types:

The most popular among listed types are OSB-3 boards, which have the widest range of applications. Applying to this species material using the previously used five-point rating scale, it can be noted that it deserves a solid “A” in categories such as environmental safety, functionality and appearance.

However, given the fact that OSB cannot be classified as an inexpensive, affordable material, for its cost it can be given a “four” rating. In addition, reviews on the operation of panels and OSB sheets mostly positive.

The moisture resistance indicators of OSB boards can be presented in the form of a table:

View	Acceptable swelling values, %
OSB-1	25
OSB-2	20
OSB-3	15
OSB-4	12

That is, the most moisture-resistant board is OSB-4, which also has the highest strength characteristics.

According to the finishing method, it is customary to distinguish between the following types of OSB:

• Varnished (on one side such plates are coated with a special varnish).
• Laminated (having laminated coating). This kind of material can be used repeatedly (up to 50 times), for example, for the manufacture of reusable formwork in production concrete works.
• Tongue-and-groove (having machined tongue-and-groove ends on two or four sides). Such slabs can be laid over the entire surface area.
• Polished.
• Unpolished.

One of the interesting varieties of oriented strand boards that have recently become very popular are Kronospan wall panels, the distinctive feature of which can be called high quality.

They have exceptional consumer characteristics: they hide surface irregularities and flaws well, do not burn and are excellent insulators.

OSB-3 is the basis for the production of sandwich panels. This term is usually understood as energy-saving structures of a three-layer type, consisting of two oriented strand boards, between which there is a core of solid polystyrene foam, which acts as insulation.

Due to their excellent thermal insulation, sandwich panels can significantly reduce the cost of heating and cooling rooms, providing an optimal vapor and air barrier and limiting air infiltration.

In addition, sandwich panels have excellent soundproofing characteristics and high strength. In practice, it has been proven that structures built from this material are several times stronger than wooden frame-type structures, etc.

Modern OSB is available in the form of slabs and panels, which can have a wide range of sizes.

However, the following parameters are considered standard for this material:

• 1220 x 2440 mm;
• 1220 x 3660 mm;
• 1250 x 6000 mm;
• 1250 x 2500 mm;
• 1250 x 3700 mm.

The thickness of the panels can vary from 6 to 22 mm.

OSB or plywood: which is better?

Due to the fact that OSB is a relatively new material that appeared on our construction market not so long ago, it is often compared with other finishing materials that have managed to “conquer their niches” in construction industry. We are talking about plywood and drywall.

Plywood is a building material made from natural wood veneer, glued together in several layers using a special adhesive composition.

If we compare OSB boards with plywood, we can note the following key points, which are quite strong arguments in favor of the former:

• The production of this material is carried out from cheaper raw materials. (OSB is made from wood chips, while plywood is made from wood veneer). That is, it is economically much more profitable and less demanding on the quality of the raw materials.
• The production of OSB boards is an environmentally friendly process that does not pose a threat to environment and man.
• OSB can be recycled.
• Plates made from this material are distinguished by their homogeneous structure. They do not have knots, pockets and other flaws characteristic of wood.
• The shear strength of OSB boards exceeds that of plywood.
• With the same parameters and dimensions, OSB sheets weigh less than plywood sheets.
• The strength of OSB does not change with changes in the humidity of the slabs.
• OSB is much more easily amenable to any type of processing, unlike plywood, which can be destroyed if handled carelessly.

However, according to some indicators, plywood is still ahead of OSB panels.

These include:

• Less susceptibility to shrinkage and deformation during operation.
• Good fixation of fasteners in sheet layers.
• Possibility of creating designs of curved shapes.
• The best decorative qualities. This moment refers to premium plywood, made from high-quality wood species (birch, cedar). However, if there is decorative covering OSB boards are in no way inferior to plywood sheets in aesthetic appeal and ergonomics, and, on the contrary, may even surpass them in this parameter.

In general, it is quite difficult to answer which is better, plywood or OSB, since both of these materials have a mass undeniable advantages And positive qualities and deserve the highest marks in the field of quality.

The term “plasterboard” refers to a material used for various types of finishing and consisting of gypsum placed between two layers of cardboard.

Its main advantages:

• Low cost.
• Light weight. Ease of installation and subsequent finishing.
• Good breathability.
• Environmental Safety.

In comparison with OSB, you can notice that drywall has greater fragility, that is, it requires a more careful and careful attitude. However, due to its technical and physical characteristics, this material is best suited for interior decoration and has a much lower cost.

Thus, the question: “Which material is more profitable and promising: OSB, plywood or drywall?” can be called insignificant. Each of them has their own positive sides and areas of application.

For example, if we're talking about on the interior decoration of walls and ceilings in premises - the best option drywall consisting of natural components can become excellent consumer qualities.

OSB boards and panels, due to their moisture resistance and affordable price – the best choice for frame-panel construction, in contrast to plywood, which, although it has the same set of characteristics, is somewhat more expensive.

As for the specifics of choosing these materials, the brand, manufacturer, thickness and dimensions are decisive. For example, when purchasing OSB, it is better to give preference to boards made in North America or Europe, which are of higher quality and contain a minimum amount of harmful impurities.

How to paint plasterboard walls with water-based paint

Which drywall is best for walls: choosing material for sheathing

Choosing a material for leveling the walls of a room is quite a difficult task even for a professional. Well, then what can we say about a beginner whose questions are “What is better - plywood or drywall?” or “What should it be optimal thickness gypsum board for cladding? will inevitably lead to a dead end.

Below we will try to understand the subtleties of choice suitable variety GKL, and also consider the pros and cons of plasterboard sheathing in comparison with the use of other building materials.

GKL wall covering

Plasterboard for covering the walls of a room

Varieties of gypsum plasterboards

Drywall is a finishing material, the basis of which is a gypsum core, protected on both sides by multilayer cardboard .

Depending on the composition of these two elements, the following types of gypsum plaster are distinguished:

• GKL - standard. This plasterboard is most widely used; it is used for covering walls and ceilings in rooms with normal humidity conditions.
  It has low fire-retardant characteristics and is therefore not suitable for use in areas where there is a risk of fire. The price of this material is the most affordable.
• GKLV - waterproof. Suitable for leveling surfaces in damp rooms, as well as where walls or ceilings are periodically exposed to precipitation, for example, on loggias.
  The cardboard layer is impregnated with a hydrophobic composition, due to which the drywall practically does not absorb moisture.

Note!
An additional advantage of GKLV is its fungicidal impregnation, which protects the surface of the material and the gypsum core from damage by fungal infections.

• GKLO – fire-resistant plasterboard. Fiberglass reinforcement is introduced into the gypsum filler, and the cardboard is impregnated with fire retardants (substances that reduce flammability).
  Moreover, even after the cardboard layer burns out, a partition made of fire-resistant plasterboard, due to sintering of fiberglass, retains its shape and prevents the spread of flame.
• GKLVO – combined, combines moisture-proof and fire-retardant properties. The most expensive type of gypsum board.

Choosing gypsum board

For wall cladding, the so-called wall gypsum board is used, the thickness of which is 12.5 mm. There are also ceiling (9.5 mm) and arched (7.5 - 8 mm) varieties of material.

Both of these varieties can also be used to level the walls of a room, but only if the requirements for the mechanical strength of the cladding are quite low.

Therefore, if you are looking for which drywall is best for partitions, then the right choice would be to abandon unnecessary savings and purchase full-fledged 12.5 mm panels.

But for the design of curved surfaces, such as arched niches in walls or window openings, it is better to use thinner gypsum board. It bends easier and puts less stress on the frame.

Arched (restoration) gypsum board

As for the answer to the question, “Which manufacturer is best to purchase drywall from?”, here most experts are unanimous. If the material does not have pronounced defects such as a crumbled core or damaged cardboard, then the manufacturing company does not play a special role.

Of course, it is preferable to buy materials from well-known companies such as KNAUF or VOLMA, but plasterboard from a local low-power plant, as a rule, turns out to be no worse.

Pros and cons of drywall for wall coverings

Very often, as an alternative to leveling walls with plasterboard, it is suggested to use other materials, such as plywood, gypsum fiber boards, etc. Below we will look at all these alternatives, but in order to give a reasoned answer, for example, to the question “Which is better - plasterboard or glass-magnesium sheet?” It is necessary to understand the pros and cons of drywall itself.

Working with gypsum board is easy and fast

The advantages of this material are worth mentioning:

• Low cost– covering and leveling surfaces with gypsum board require significantly less financial costs than the use of other materials.
• Ease of operation. You can easily install plasterboard boards yourself, and you will not need any complex and expensive tools.

Note!
The website contains lessons on using drywall to solve various tasks, and also provides instructions for working with the main types of gypsum board.

• Possibility of further decorative finishing . After installing the gypsum board and filling the plasterboard seams, you can glue wallpaper, apply plaster, and, if leveled properly, even paint it on the leveled surface.
• Safety and non-toxic. Giprok does not contain toxic substances or heavy metals, so its use in the interior is completely harmless to humans.
• High sound insulation characteristics .

However, there are several disadvantages:

If handled carelessly, the casing can be damaged.

• Relatively low mechanical strength.
• Even GKLV is not able to withstand direct exposure to moisture for a long time. When wet, this material swells and deforms, and the surface covered with it has to be dismantled and restored.
• Without decorative finishing, gypsum board cladding looks unpresentable, so spend money on wallpaper, paint or decorative plaster still necessary.

It is this combination of pros and cons that is typical for drywall. Now let's try to compare this material with the alternatives that the construction market offers us.

Alternatives to drywall for leveling walls

Gypsum fiber sheet

GVL is the most popular alternative to gypsum board

Gypsum fiber sheet (GVL) is a panel of pressed gypsum reinforced with cellulose fiber. Sometimes GVL is used as an alternative to gypsum board, especially in rooms with high humidity.

When answering the question of which is better - drywall or gypsum plasterboard, the following arguments are given:

• Gypsum fiber has significantly less ductility, which is why gypsum board is most often used for shaped structures such as arches or curved niches.
• It is also better to use plasterboard for partitions and finishing window and door openings, since GVL slabs It's quite difficult to mount it well here.
• But for leveling vertical surfaces, especially in rooms with high humidity (bathroom, toilet, loggia), a gypsum fiber sheet is more suitable.

Simply put, it depends on the task facing us which is better - plasterboard or gypsum fiber.

Glass magnesium sheet

Glass-magnesium building sheets (FMS) are a finishing material based on a magensite binder. The basis of the sheet is fiberglass, and magensite, magnesium chloride, perlite and other components are used as filler. Appearance glass-magnesium sheets are shown in the photo.

Thanks to the spread of glass-magnesium sheets, discussions often arise about what is better - glass-magnesium sheet or plasterboard?

And there are several points of view here:

• On the one hand, LSU is significantly superior to drywall in terms of mechanical and moisture-proof characteristics. The structure of glass-magnesium sheet is such that it can remain in water for more than 100 days without deformation, which makes it suitable for both interior and exterior decoration.
• On the other hand, glass-magnesium finishing panels They are quite expensive, and it is more difficult to process LSU than standard gypsum board.

Therefore, it is quite difficult to make a clear choice in favor of one material or another. If you need high stability of the cladding, then you should choose LSU, but for most interior work, plasterboard is at least as suitable.

Plywood and OSB

As a material for finishing walls of premises (especially in wooden houses) many suggest using plywood or oriented strand board - the so-called OSB.

Wall covering with plywood

When analyzing which is better - plasterboard or plywood, you need, as in previous cases, to take into account the characteristics of the room and the purposes for which we use the material:

• Both plywood and oriented strand board are made from natural wood raw materials. On the one hand, this provides them with a number of advantages, but on the other hand, it causes deformation of plywood boards.
• As for flexibility, here too the choice is in favor of drywall. The thing is that it bends relatively well only thin plywood, and it is almost impossible to bend thicker slabs without the risk of cracking. The same applies to OSB boards.
• Processing plywood panels is much more difficult than working with drywall. In addition, even if there is a slight error in dimensions, the entire sheathing sheet will have to be replaced. From this point of view, gypsum board is a much more convenient material.
• Don't forget about the cost of plywood and OSB. Leveling walls using gypsum plasterboard will cost you much less than using wooden panels.

If we analyze the construction market, there are still many alternatives to gypsum board, and therefore disputes like the discussion “Which is better - OSB or plasterboard?” will probably never stop. But it is worth taking into account that each finishing method has both pros and cons, and as for the price-quality ratio, plasterboard is, perhaps, beyond competition!

The use of sheet materials in construction and home decoration has long been known. But if in the past it was necessary to make do with only chipboard, fiberboard or plywood, today the ranks of traditional samples have been replenished with new analogues with improved properties, which makes them more suitable for certain types of work.

One example of such products is OSB boards for interior decoration, which will be discussed further.

What is OSB board?

OSB is an oriented strand board. The material is panels made from pressed coniferous shavings And hardwood trees. Chip sizes can range from 60 to 150 mm.

OSB boards have high strength and density, thanks to the combination of several layers. In the middle the chips are located across the sheet, and in the lower and upper layers- along.

All layers of material are pressed under high temperature and pressure and impregnated with waterproof resins and paraffin. Used as a binder phenol and formaldehyde resins. The finished slabs have a uniform structure - without cracks, chips or cavities.

Read more about the characteristics of OSB in our article.

Is it harmful to use slabs for interior decoration?

The possibility of using OSB for finishing depends on the labeling of the product, which in turn is determined by the amount of synthetic resins in the material that emit during operation harmful fumes.

The largest amount of toxic substances (from 10 to 30 mg per 100 g of dry matter) is contained in slabs of class E2 and E3. OSB panels marked E0 and E1 contain a minimum proportion of harmful components - from 6.5 to 10 mg. This is usually a product foreign manufacturers: Glunz (Germany), Norbord (Canada), Egger (Austria).

Thus, the products of the last two brands are most suitable for use for interior decoration.

Materials of class E2 and E3 can only be used for outdoor work.

To protect yourself from purchasing “hazardous” material, it is worth considering some points that partially determine right choice OSB:

• the smell of stoves. At high content harmful substances the material smells strongly of formaldehyde and cheap plastic;
• products must have a certificate certified by a seal from the manufacturer or supplier. A copy of the document can be requested from the seller;
• It would also be a good idea to inspect the packaging, if available. Products from serious manufacturers are usually labeled and equipped with information inserts.

How to make a partition from OSB inside a house and what screws to use?

OSB is a completely suitable material for construction internal partitions rooms. The strength and light weight of the sheets are clear evidence in favor of this product. OSB boards can be mounted on (like gypsum board) or on a wooden frame.

If the second option is used, the wood should be treated with protective materials against mold and mildew, as well as fire retardants.

Now as for partition installation diagrams, which will be considered using the example of a wooden frame:

1. Markings are made at the installation site of the structure. Lines are drawn along the floor and ceiling, which will serve as guidelines for installing horizontal guides.
2. Beams with a cross section of 4x6 cm are attached along the marking lines. If the wall will be subjected to serious loads (for example, you plan to hang furniture on it), it is better to use thicker bars - 5-8 cm. The guides are attached using dowels.
3. Install vertical racks, which are fixed to horizontal bars using metal corners and screws.

The pitch between the racks depends on the width of the slab, which varies. So, if the transverse size of the OSB sheet is 125 cm (the value characteristic of European brands), then the optimal distance between the axes of the vertical beams is 62.5 cm. In this case, it will be possible to screw the edges and the middle of the slab to the frame.

4. After installing the racks, OSB panels are installed.

They are attached using self-tapping screws, the length of which depends on the thickness of the sheets and should be 45-50 mm greater than this value. For example, when using material with a thickness of 12 mm, the recommended length of screws will be 60-65 mm.

Screws are screwed into the middle of the slab in increments of 30 cm, along the edges - every 15 cm. The distance from the edge is 1 cm. A gap of 1 cm is left between the slabs and the floor. The same gap should remain between the OSB and the ceiling.

Also, the panels should not be installed closely, but at a distance of 3 mm from each other. This will protect the sheets from deformation due to changes in humidity.

Making a partition from bars and OSB - watch the video:

Internal wall cladding

This process, just like the procedure described above, requires the preliminary construction of a frame, for which the same wooden beams or profile are used. Now an example for arranging the sheathing will serve metal version, since the wooden frame was discussed earlier.

Finishing walls with OSB boards consists of the following steps:

1. The first step is, as always, marking.

If the wall is uneven, you should find the part that sticks out the most, from which you should start. Lines are drawn along the wall, after which the starting UD profile is attached to the floor and ceiling using self-tapping screws or dowels.

2. Next, vertical CD profiles are inserted into the installed guides and also fixed - to the wall using self-tapping screws and metal hangers, to the horizontal guides - with drilling screws. The pitch between the posts is the same as in the case of a wooden frame.
3. To give rigidity to the sheathing, the vertical posts are reinforced with transverse profiles. At standard height For ceilings (2.5 m), it will be enough to install two elements for each span.

The installation of the slabs is carried out in accordance with the rules mentioned in the instructions for the construction of partitions.

How to finish the slab indoors?

The interior decoration of wooden country houses as in the photo can be completely different in cost and design. For surface finishing OSB sheets are used various materials. Let's consider them further.

Is it possible to attach drywall to OSB?

Can. Moreover, for this it is not necessary to use a metal profile, but simply screw the material to the base with self-tapping screws.

The main thing here is that The humidity level in the room was not high, since otherwise this can lead to deformation of the OSB and, consequently, the plasterboard sheathing itself. Self-tapping screws are screwed in around the perimeter and in the center of the gypsum board in increments of 10-15 cm.

Painting with varnish and acrylic paint

Varnish increases moisture resistance OSB boards. This finishing method is good for use in damp rooms. The boards can be painted with any varnish intended for natural wood. The surface is cleaned of dirt, degreased, sanded and treated with a primer. Varnished OSB has a smooth surface, but retains its texture.

Also a good option for finishing OSB is. It rolls well on the surface with a roller and forms a durable and breathable coating.

To get the best effect, it is advisable to paint in two layers.

Puttying with gypsum putty

Putty materials do not adhere well to wood. Therefore, it is best to use formulations that have maximum adhesion to wooden surfaces. These can be dry mixtures “Rodband” or “Goldband”, containing polymer additives and most suitable for working with wood. You can use Vitonit KR as a finishing coat.

Before puttying OSB primed with a special composition, where glue, interlining and a little putty mixture are added. If this measure is neglected, the base impregnation may bleed onto the finished surface, causing the finish to become stained.

How to plaster a surface made of OSB boards?

For plastering OSB, it is best to use a special mixture. Eg, Knauf Sevener. The plaster finishing technology itself includes the following steps:

• The joints between the slabs are puttied and covered with sickle tape.
• The surface is treated with a primer (you can take Knauf Tifengrund).
• Apply the first layer of plaster and embed the reinforcing mesh into it.
• A covering and leveling layer is applied on top.

Glass wallpaper sticker

If the slabs smooth (polished), wallpaper can be glued directly onto them. Otherwise, you will have to plaster and putty the surface, doing this using the technology described above.

Fiberglass wallpaper is glued to special compounds. In this case, the dry mixture “Methylane Fiberglass Premium” and the granular composition “Methylane Granulate Premium” are suitable.

Find out how to hang wallpaper on OSB from the video:

How to glue ceramic tiles?

There are several ways to stick this on:

• fix the expanded mesh to the surface and lay the cladding on any adhesive for ceramic tiles;
• perform installation directly on the OSB board using glue for deformable surfaces;
• use epoxy grout instead of adhesive.

Liquid wallpaper

This type of finish is applied to OSB in the same way as to an ordinary wall. All you need is prepare the foundation, sealing the joints and treating the surface with a primer.

Behind 12 hours before work starts the composition is kneaded and left in a plastic bag. Ready material Apply using a spatula in an even layer from 3 to 7 mm.

One of the advantages of such a material is that it is not afraid of small surface defects. They simply smooth out when the mixture is applied.

Is it possible to sheathe a bathhouse and a garage inside with an OSB board?

OSB sheets are a material that is suitable not only for finishing residential premises. It can also be successfully used for siding or garages.

In the first case, of course, you need to use only environmentally friendly brands of material.

OSB should be treated in the bath 2-3 layers of water-soluble varnish, which will add shine to the surface and protect it from moisture.

As for the plating, here Suitable for OSB of any marking, since in non-residential premises, concern for the environment is the tenth thing and the harmfulness of the material does not matter.

From all of the above, we can conclude that OSB boards are a universal product suitable for use with various types of finishing. This quality, combined with the strength of the panels, makes OSB a worthy representative of the category of sheet materials.

How to putty OSB with your own hands - a detailed course for beginners:

Among the huge range of finishing materials, plasterboard and oriented strand boards are deservedly popular. Both options have their strengths and weaknesses. And to figure out which is better, OSB or drywall, you need to familiarize yourself with them in more detail.

What is drywall, its pros and cons

Drywall can rightfully be called one of the most versatile materials for home interior decoration. With its help, you can create perfectly smooth walls, make structures of any complexity in the form of arches, original niches, multi-level ceilings, pilasters, columns and much more.

This versatility of drywall is ensured by its base, which is a natural material obtained by firing at a temperature of 1800 degrees - building gypsum.

In addition to gypsum, the filler may contain PVA adhesive, starch, fiberglass, etc.

The gypsum, ready for further processing, is placed between two layers of thick cardboard. To make plasterboard sheets, cardboard with a density of 0.17 - 0.22 kg/m2 is used.

To ensure that this building material has a reliably protected edge, its edges are folded around the ends. This technique allows you to protect the sheet during transportation or storage.

Pros of drywall:

• Naturalness of the material. No synthetic additives or toxic substances are used for its production, which allows you to obtain an environmentally friendly finish inside the house.
• Can be used in any room, but for use in places with high humidity levels (for example, in the bathroom), it is recommended to choose moisture-resistant gypsum board
• Does not cause any difficulties during installation work. The material lends itself well to any processing and is easily modified. This advantage of gypsum board allows you to create the most incredible designs and reliefs
• The ability to hide various communications in plasterboard niches, as well as uneven walls. Insulation material can be laid in the voids formed during the installation of drywall.
• High thermal and sound insulation qualities
• The ability to create a comfortable, controlled microclimate in a room finished with plasterboard that can absorb and release moisture
• GKL has a good fire safety rating
• Plasterboard structures lend themselves well to painting, plastering, tiling, and wallpapering.
• Possibility of quick and relatively simple repairs in case of cracks, dents, deformation, or through holes
• Availability of material

Disadvantages of plasterboard finishing:

• Moisture-resistant drywall, often used in bathtubs, cannot fully withstand the negative effects of water. It is not recommended for use for finishing ceilings in multi-storey buildings, where there is a high probability of flooding by neighbors above
• In rooms with high humidity levels, even with special surface treatment, it is not always possible to prevent the appearance of mold on gypsum boards. Only by installing waterproof materials during finishing can you achieve the desired result
• Low mechanical strength of the material, which suggests strengthening the future structure with the help of embedded elements when attaching lighting fixtures or in places where paintings, equipment, household items, etc. will be hung.
• Precision and accuracy when working with gypsum plasterboard; fastening must take into account the characteristics of the material
• The need for additional finishing (sealing seams, recesses)
• Availability of a dry room in case of storing sheets in reserve

In order to understand which is better - drywall or OSB board, it is recommended to study the strengths and weaknesses of the latter.

What are OSB boards, their pros and cons

Oriented strand boards (OSB, OSB, OSB) are made in the form of a multi-layer sheet texture from coniferous or hardwood chips made from non-commercial wood. The chips are glued together with a variety of resins under high pressure and high temperature. On the outer side of the sheet, the chips are laid out longitudinally, and on the inside - transversely, which makes the slabs especially durable.

Advantages of the material:

• Can be bent if necessary for interior wall decoration. Unlike plywood, it does not crack
• Moisture-resistant options can be used for external cladding of gazebos and outbuildings. The OSP-3 and OSP-4 grades with a high level of resistance to moisture have proven themselves especially well.
• When fastening the material does not cause any difficulties, the screws are securely held in the structure of the canvas
• The slabs are easy to process, fastening them is quite simple, and you can cut them to size with a chainsaw
• Availability of material
• Wide choice of finishes, you can use varnish - colorful materials, plaster, etc.
• Long service life if attached according to technology. If the slab is treated with a fire-resistant compound, it can last up to 300 years.
• High degree of strength
• Does not shrink
• The material contains no harmful components
• If you cover the slab with high-quality varnish, the surface will be complete

Disadvantages of OSB boards:

• There are products from manufacturers that add glue with formaldehyde and other substances harmful to human health.

When purchasing a product, you need to pay attention to its quality and composition.

To answer the question “Which is better, plasterboard or OSB for interior decoration of a house?”, you need to compare these two types of material.

Comparison of gypsum board or OSB

To find out which is better, OSB or plasterboard on the walls for interior decoration, we will compare the following parameters:

• Scope of application. Both gypsum board and OSB can be actively used to create furniture (in the kitchen), ceiling and arched structures, and shaped elements. Using moisture-resistant options, you can cover the walls in the bathroom.
• Environmental friendliness. Two types of material, when manufactured with high quality, do not contain substances harmful to the human body.
• Moisture resistance. GCR is more susceptible to the development of mold on it than its opponent. If we consider what is better to mount on the bathroom wall, plasterboard or OSB, then it is better to give preference to universal products - OSB-3 with a high level of moisture resistance and susceptibility to mechanical loads.
• Strength. This is where oriented strand boards win.
• Difficult to process. Both materials are easy to process, and their load capacity is relatively high.
• Thermal and sound insulation qualities. If there are excessively loud sounds, the gypsum panel will vibrate. To eliminate this negative point, you will need to finish the surface with several layers of cladding and fill the voids with fiberglass or mineral wool. But today the manufacturer has presented a unique product - acoustic plasterboard with excellent soundproofing properties. It attaches very simply. With this approach, both materials will have almost the same effect.
• Difficulty at work. If you figure out what is better to mount, OSB or drywall, then there is not much difference. They attach equally well and do not cause any difficulties even for a home craftsman.

In which cases is it better to use OSB, and in which plasterboard?

For finishing roofs, for covering floors, for exterior work, for creating frame-panel construction, it is recommended to use oriented strand boards with high technical characteristics.

For interior wall decoration and original designs, choose a material based on building gypsum.

Having found out which is better than OSB or plasterboard, you can begin planning renovations in a specific room. The main thing is to choose a product from a trusted manufacturer and install it reliably and efficiently, following construction technology. If moisture-resistant drywall is mounted on OSB, you can get a surface with a long service life and quite strong.
