Which is better OSB board or plasterboard? My friend and I are laying plasterboard on walls without a frame throughout the apartment. Which is better: plasterboard or OSB board?

Among huge assortment finishing materials Plasterboard and oriented strand boards are deservedly popular. Both options have their own strengths and weak sides. 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 Houses. With it you can create perfect smooth walls, produce 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 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 are used for its production and toxic substances, which allows you to get 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 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 to be used for finishing ceilings in multi-storey buildings, where there is a high probability of flooding by neighbors above
• In rooms with increased level humidity, even with special surface treatment, it is not always possible to prevent the appearance of mold on gypsum boards. Only installing at finishing waterproof materials, you can achieve the desired result
• Low mechanical strength of the material, which requires reinforcement future design using embedded elements for 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 - 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. Chips are glued together with various resins under the influence of high pressure And high temperature. On the outside of the sheet, the chips are laid out longitudinally, and with 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 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, let’s 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 sheathe 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 a 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 board 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 big difference there is no. 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.

Start repair work involves searching for materials, deciding to hire a team, or hoping for own strength. And even if it was decided to improve your own home yourself or the utility room needs to be repaired.

In any case, you will have to watch master classes and get acquainted with the advice of experts. After all, the microclimate in the room will often depend on the chosen material.

And then a fair question arises: which material will be better for cladding indoors or outdoors. The sheathing is not the final layer; carpet or linoleum is often attached to it without any problems, tiles or tiles are laid, wallpaper is applied and paint is applied.

First of all, various similar Construction Materials used for insulation, sound insulation and moisture absorption. Let's compare the advantages of gypsum fiber sheets and oriented strand board.

GVL or OSB

Each of the materials is environmentally friendly and natural products. However, they have absolutely different characteristics and properties. GVL are sheets of building gypsum that are reinforced with cellulose. Thanks to this technique of creating of this building material, it is quite strong, but fragile. Gypsum fiber also perfectly blocks noise, retains heat and has a marked moisture-resistant appearance. Uses: wall, ceiling, floor, exterior cladding and partitioning. At the same time, they GVL burns very poorly. It is suitable for apartments and houses, and for public premises. But all these properties affect high price material.

The second material, OSB, is several sheets glued together, the composition of which is one hundred percent natural, wood chips. They are pressed and glued together using resin, artificial wax, and boric acid. It is important that for external or internal lining The slabs differ in the pressing method. For external ones - longitudinal chips, for internal ones - transverse. These boards have different markings, including OSB, which can withstand humidity conditions.

Due to its composition, the price of OSB is significantly lower than that of GVL. Particle boards just as durable. They are distinguished by their quality of workmanship and pleasant appearance, there will be no indoors unpleasant odor thanks to minimal use synthetic adhesives. They weigh little, so it’s easy to work in any plane. And you have to try really hard to break the slabs.

These slabs, like gypsum fiber boards, can be processed without difficulty. The issue of unwanted residents among the shavings should not bother the consumer. Thanks to special treatment, this is impossible. These slabs can also be used to cover walls and can become the basis for laying roofs and floors as an intermediate layer.

There are some points that can be decisive when choosing a material:

• it is not easy to lay tiles or tiles on OSB boards;
• the surface of oriented strand boards is not perfectly flat compared to gypsum fiber board;
• chipboards, of course, are quite flammable;
• moisture-resistant properties are still different and preference is given to GVLV.

GVL or SML

Let's consider another option for replacing GVL with SML. SML is a glass-magnesium sheet; the material also has many other names, but they are all the same thing. It is a building material that is created on the basis of magnesium binder. Do not worry about its composition, it is safe for humans and is widely used for finishing residential and public premises. Glass magnesium sheets have the main advantage over other finishing materials - resistance to fire.

LSU is used for covering walls, floors and ceilings, and creating partitions. The same can be said for GVL. However, manufacturers often “chemically” change the composition of these building materials. Therefore, experts recommend buying only if there is detailed labeling and a verified supplier. Each of the materials is practically not afraid of fire; GVL and SML are often used for cladding elevators, for example.

The price also varies, GVL is much more expensive. LSU is characterized by high fragility; when working with it, a lot of debris is generated. Difficulties may arise when laying the finishing layers of tiles and wallpaper.

GVL or SHG

GSP is gypsum particle boards or sheets that are used only for interior decoration. They can be used to cover walls, floors and ceilings. The composition allows us to call it environmentally friendly and fire resistant. The shavings are the main element and are bound with building plaster.

GSP can withstand quite well wet areas, only if it arrives periodically. It is also quite durable. External noise passes through it with difficulty. Thanks to gypsum base easily absorbs and releases moisture when needed. Thus, like GVL, it is able to create a comfortable microclimate in the room. It is easy to work with gypsum particle boards, saw, cut and apply any finishing layers.

She has perfect flat surface, like GVL. If large loads are planned, then GSP is recommended for cladding. Its price is much higher than GVL.

GVL or DSP

DSP is a cement-bonded particle board. Its composition is quite simple:

• wood shavings;
• cement;
• special chem. additives to reduce the influence of wood on cement.

This building material is extremely durable, breathable, non-flammable, does not allow sound to pass through, is waterproof and is practically impossible to rot. It is suitable for external and internal cladding of rooms, walls, ceilings, floors, and the base for roofing.

Thanks to high density, is enough heavy material, and working under the ceiling is no longer as easy as with GVL. He has low level flexibility, and does not apply to fragile building materials. Despite the high resistance of GVL to moisture, cement-based CBPB is better. The price of cement particle board is cheaper than GVL.

GVL or plywood

Plywood is multilayer sheets based on a special veneer that is glued together. The number of layers may vary. There are painted moisture-resistant sheets. Used in residential premises and frequent use.

The sound insulation properties are much lower than GVL, but at the same time they are several times stronger. When producing plywood, there is no strict monitoring of the ideal sheet thickness along the entire perimeter. When working with it, a lot of chips fly away. Not bad for leveling the floor; professionals even prefer plywood over gypsum fiber board. The price of gypsum fiber is much higher due to the composition and production method.

The modern range of building and finishing materials is wide and diverse. Here you can find almost any material, or rather, something that meets all your technical needs or personal preferences. For example, OSB, drywall (gypsum plasterboard) or gypsum particle board (GSP). They have a lot in common, which is why they are used for interior decoration. On the other hand, they have many differences and features. Preference should be given based on the specific requirements of the upcoming repair, finishing or cosmetic repairs and partial redevelopment.

So, the differences are based on raw material and the composition that forms a particular material. Thus, the GSP board consists of 83% gypsum, 15% wood chips and 2% moisture. Drywall consists of 91.1% gypsum, 5.78% cardboard and the rest water. Externally - gypsum core and covered with two layers thick paper or cardboard. OSB presented sawdust(95%), the quality and type of which largely determine the properties of the future slab, and a certain amount of impregnation, that is, paraffins and glue. In some cases, it is additionally treated with wax, which increases its moisture-resistant qualities. With regard to drywall, everything is simple: the middle layer is a hardened mixture of gypsum, and the entire sheet is a core glued to the cardboard. OSB, like gypsum particle board, is manufactured in compliance with strictly defined temperature parameters and under a certain pressure. Hence their high strength and wear resistance.

Today you can buy GSP or OSB, gypsum board of any desired size. Especially if you contact the manufacturer. For example, gypsum particle board is produced in the same sizes as plasterboard. And interior finishing with this material is also simple and convenient. OSB is slightly different in size. The main thing here is the uniqueness of some of their properties. Namely:

• OSB is highly moisture resistant. This includes the presence of special impregnations, the use of paraffin in the composition, and rubbing the slab with wax. No plaster;
• The environmental friendliness of GSP is the highest: the complete absence of adhesives and resins, mastics and paraffins in the composition. These substances are not needed during the production process of the material;
• ease of installation and cost-effectiveness. This quality is important, but it is not so easy to track. Thus, GSP is more profitable and economical to use, because it is easier to make corners and bends with its help than drywall. OSB in these qualities is close to gypsum particle board, and these properties completely depend on the type of wood and impregnation from which it is made;
• lightness or density. OSB has a density of 650 kg/m³; GSP – 1100-1200 kg/m³; GKL – 750-800 kg/m³. You can immediately see what is easier and what is harder. Lightness speaks not only about physical weight, but also about the degree of reliability of the structure. It’s easier and more convenient to work with lightweight sheets, but it’s worth remembering that you can just as easily break through a plasterboard wall.

Now a little about the areas of application. Today, interior decoration of both SHG and OSB premises is widespread. Everyone has their own preferences. The most popular material is plasterboard, followed by gypsum particle board, which is convenient to work with. In addition, floors, walls and ceilings made of GSP are highly durable, environmentally friendly and have lower consumption of primer, grout and paint, which are necessarily used for interior finishing work.

There are a lot of finishing materials on the market. And among such abundance, the most popular are plasterboard and OSB boards. Finishing in which plasterboard is mounted on OSB is often used. How justified is this? Each of these materials has positive characteristics and disadvantages that are worth considering in detail in order to understand which of these materials is preferable in construction.

It's impossible to understand what better than drywall or OSB without considering these materials in detail. Each material is unique. Has positive and negative properties, as well as its own nuances during installation.

Drywall

GCR is by far the most in demand and popular among builders. And this is not surprising; the structure of this material gives it a lot of advantages.
comprises:

• core – compressed gypsum mixture, special properties which is achieved by adding special additives to gypsum;
• thick cardboard - 2 layers, which is located on both sides of the core.

Plasterboard sheet

This device gives drywall a lot of advantages:

• it is an absolutely harmless environmentally friendly material;
• small specific gravity. It will not be difficult for even one person to carry out the installation;
• simplicity in arrangement of structures;
• lasting;
• durable;
• plasterboard slabs are an excellent basis for further finishing with any materials; in addition, you can create any;
• possibility of using insulated walls, arches, and niches;
• price - if you are making repairs in a house or apartment, then it is easier and cheaper to use plasterboard than any other building material.

Using plasterboard slabs you can transform the interior of your apartment, making it exclusive and unusual.

To summarize: GCR can be used in almost any room, be it a bathroom, attic or loggia.

Flaws

The material has many advantages, which is why it is popular among developers, but despite this, it is worth talking about the disadvantages:

• before you hang on heavy object, even when installing the frame, you need to install mortgages;
• if a heavy object is incorrectly fastened to the wall, the slab may become deformed from the weight;
• When processing and cutting material, fine dust is generated, which can cause allergic reactions by inhalation, therefore you need to wear protective clothing;
• the frame that is assembled for takes up useful space.

These are non-critical indicators. Sticking to strict rules in terms of assembly, they can be minimized; the only negative that remains is the reduction in space.

Purpose of the material

Drywall can be used in the following cases:

1. Leveling the walls is even used when finishing the attic.
2. of any complexity.
3. Installation of furniture of various configurations.
4. , shelves, and decorative elements.
5. Construction of stands.

This material has many more advantages than disadvantages, which is why it is so popular.

Important. Before you start installing this material, you need to determine what you want to get in the end; this is the only way to accomplish high-quality arrangement interior

OSB panels

Increasingly, OSB boards are used in construction, which are usually used in conjunction with insulation for construction frame buildings. The material has proven itself so well that it is often used for cladding indoor and outdoor surfaces.
What are the slabs made from?

• wood shavings;
• resin;
• boric acid;
• synthetic wax.

This material consists of 95% chips, 5% resins and adhesive. The quality of the slabs depends on the type of wood from which it is made. For moisture resistance, the slab is covered wax composition.

Properties of OSB board

Due to its texture, the material has many advantages:

• reliability;
• affordability;
• resemblance to a tree;
• low specific gravity;
• high quality;
• durable when used correctly.

Characteristics of OSB slabs

OSB has certain properties:

1. High strength indicators.
2. Moisture resistant when properly processed.
3. Easy to use.
4. Rigidity.
5. Sound absorption.

OSB is an excellent material that can be used for interior decoration, and it is used without.

Flaws

Except everyone listed advantages OSB boards have a number of disadvantages:

1. Boards from manufacturers from Canada and Poland are moisture-absorbing. As a result, they swell and are subsequently unsuitable for installation work.
2. The slabs are divided into environmental classes. The safest markings are E0, E1. The rest, starting with E2, emit phenol, which is dangerous to human health. This component is released especially strongly at temperatures from +30 and above.
3. Before purchasing OSB boards, you should carefully study the quality certificates and the compliance of the boards with these certificates.
4. Particular attention should be paid to manufacturers from China.

When checking the reliability and safety of OSB boards, they are used in installation work indoors.

Installation of OSB board

The process of producing boards is quite simple: large wood chips are pressed using glue, which causes the release of toxins into the air.

Important! If you have doubts about the safety of OSB, then you should know that for chipboard production the same glue is used, only in more. OSB is less toxic.

In addition, there are the most significant disadvantages:

• low fire resistance;
• if you need a durable surface, you have to lay the material in several layers;
• installation is much more difficult than that of drywall;
• generates a lot of debris and sawdust during processing;
• the material is practically vapor-tight.

The best option for finishing rooms with this material is the attic, bath or kitchen, interior decoration frame house.

OSB on the floor

What is OSB used for?

In construction, slabs are used:

The material appeared on the market not so long ago, but thanks to its positive characteristics has become widely used in construction. Of course, its low cost also plays an important role.
These materials are often used in tandem, since OSB boards are very difficult to finish decorative coatings, then it is often used, which are much easier to veneer. This makes the structure durable. This is the answer to the question: is it possible to attach drywall to OSB for interior decoration? The video talks about application of OSB slabs
