What is more environmentally friendly: plywood or drywall? Comparison: which is better, GVL or OSB, SML, GSP, DSP, plywood? Differences and similarities of facing materials

This article will help you make an informed choice in favor of one material or another.

Plywood- this is a material consisting of veneer, which is glued in several layers using glue.

The following facts speak in favor of using plywood:

wide scope of application;
high decorative properties. This is especially true for elite and first grade plywood;
minimal susceptibility to deformation and shrinkage processes;
regulated content of formaldehyde components;
ease of processing;
good fixation of fasteners in layers;
moisture resistance;
the ability to return plywood to its original shape after exposure to moisture;
the ability to create bent shapes;
equal strength over the entire plane of the sheet;
no through cracks.

Plywood and OSB are the two most similar materials. Difference in in this case consists only in the fact that in plywood the veneer sheets are solid and are located perpendicular to each other from the point of view of the structure of the wood fibers. In OSB sheets, the chips are located chaotically. In general, the material is created from the same raw materials. Therefore the question is What is stronger: plywood or osb- does not have a clear answer. It all depends on the thickness of the product, the type of wood used, and the quality of the glue.

Benefits AboutS.B.

high shear strength. What is achieved due to a more uniform texture;
low manufacturing cost, affecting the price of the final product;
waste-free production;
recyclability;
less weight, with the same sheet thickness;
minimal susceptibility to delamination of material components;
possibility of covering the material with film or veneer.

The given product characteristics allow us to conclude that Which is cheaper: plywood or OSB? The latter has the advantage. To be fair, it should be noted that this is almost the only advantage of OSB over plywood. The strength characteristics of these materials are identical.

Chipboard or plywood which is better?

Often at the time of purchase the question arises, Which is stronger than plywood or chipboard??

To answer this question you must first decide How does plywood differ from chipboard?

Chipboard is a chipboard, in the production of which the same material is used as in the production of plywood. However, the manufacturing technology is more similar to OSB technology. In this case, the wood is crushed into small particles, mixed with a binder and placed under a hot press. This is exactly how the process of making chipboards occurs.

Advantages of chipboard:

the homogeneous structure of the chipboard provides it with high fracture strength;
high heat and sound insulation properties;
not high cost.

MDF is a compressed wood fiber board medium density. It is made from wood waste (dust).

Advantages of MDF:

high fracture strength;
resistance to fungi and other pests;
long period of operation;
low cost.

What better than fiberboard or plywood?

Fiberboard - compressed fibreboard high density.

Advantages of fiberboard:

high strength;
low cost;
long service life;
high thermal insulation rates.

However, despite these indicators, fiberboard has become more widespread not in construction, but in furniture production.

What better than drywall or plywood?

Drywall- a new product that has replaced traditional wood materials. It is essentially plaster of Paris placed between two layers of cardboard.

It is difficult to compare these two materials because they have different compositions and manufacturing technologies. When using them, they are used various instruments. But, for example, in those areas where these materials can be interchangeable, we can talk about comparison.

Advantages of drywall:

ease;
low cost;
ease of use;
ubiquity of use in interior decoration.

What is better gvl or plywood?

GVL - gypsum fiber sheet. In structure, raw materials and manufacturing technology it is similar to plasterboard. Additionally contains cellulose waste paper, which acts as an amplifier.

Advantages of GVL:

Possibility of use in rooms with humidity levels up to 70%;
low heat absorption coefficient;
high level of sound absorption.

Conclusion

Summarizing the above, we can conclude that the answer to the question Which is better plywood orosb, fibreboard, chipboard, MDF, plasterboard or other material - depends on the scope of its potential application. Depending on the requirements imposed on the material by operating conditions. The size of your budget also influences your choice.

When building a house, as well as finishing it, it is very important to decide on the materials that will be used. So, which is better, plywood or drywall, those who encounter types of finishing for the first time ask themselves. Both of these materials are quite economical and are used almost always.

Drywall and plywood are widely used in home construction and decoration. They are almost in the same price range.

Of course, plywood is a more environmentally friendly product, it is made of natural material, and drywall is nothing more than ordinary cardboard impregnated with a special composition.

Plywood is great for laying on laminate floors, and plasterboard is used for leveling walls or creating various design solutions inside the house.

For creating interior partitions ideal material is drywall.

It should be taken into account that drywall is resistant to moisture. Therefore, it is often used in the kitchen, bathroom or other places associated with dampness.

For the interior decoration of a house made of timber, plasterboard would be better, because when the temperature changes, condensation occurs, and plywood does not like moisture and can warp.

When creating interior partitions, a better material than plasterboard has not yet been invented, so it remains to be recognized as the first choice. However, such walls are quite thin, with little sound insulation.

It cannot withstand heavy loads and, naturally, gives way natural wood, but has a very smooth and smooth surface and does not depend on the vagaries of the weather.

What is better to choose for your home?

Production scheme plasterboard sheets.

What to take instead of drywall, everyone decides for himself, but for leveling ceilings and walls better material haven't figured it out yet. Gypsum plasterboard, or gypsum board, is fire-resistant and moisture-resistant, used not only indoors, but often also outdoors. This material even protects facades from the wind and is also used for restoration.

For interior spaces They use two types of gypsum boards: reinforced heavy-duty and flexible sheets. Unlike regular drywall, Knauf has excellent soundproofing properties and it is also a good insulator. If necessary, drywall can be painted several times, which means changing the design of the room.

Plywood does not like repainting and does not look as aesthetically pleasing; it is better to apply wallpaper on it if it is chosen as the basis for walls.

Technology system production process in the manufacture of plywood.

Each type of gypsum board is good in its own way and is used in different conditions. The moisture-resistant type is intended for baths, and the heavy-duty type is intended for walls and ceilings, which can be done in several levels. In addition, this material is relatively inexpensive.

You can’t expect such properties from plywood; it not only burns better, but also tolerates moisture less well, but it is also often used in construction.

Some contractors don't like to deal with drywall so they offer plywood as sheathing, but don't compromise on quality.

Differences and advantages of materials

Drywall has more advantages than plywood: it is resistant to moisture, it is good for gluing wallpaper, it is easy to install and allows you to create flexible structures.

Moisture and fire resistance. Don't forget about the benefits of drywall.
Material cost.
Installation of flexible structures is impossible when using plywood, so the more complex the design of the premises, the less chance there is of this material.
It is difficult to apply wallpaper and other finishing materials to plywood, since it has various impregnations, which impairs the quality of work.
When installing drywall, you can get by with a minimum of tools and skills; it is very easy to work with.

However, if the room is dry and the strength of the walls is needed, then you can choose plywood for sheathing work.

Drywall is also very convenient for installing wiring and other elements. utility networks. It is easy to process and hides uneven walls and ceilings. For plywood sheathing, smoother surfaces are needed, otherwise the material begins to play.

Where are these finishing materials used?

Due to its strength, drywall can also be used to construct shelves and niches.

Depending on the thickness, you can use both plasterboard and plywood, not only for covering walls, floors and ceilings, but even in the manufacture of furniture. Drywall can replace shelves and niches; it can be used to make any arch or make concave walls. Interesting design solutions Almost always done through the use of drywall. Therefore, this material has a wider range of applications.

Anyone who is not interested in frills may prefer wood, which is environmentally friendly and strong, but will cost more. You can see exactly how to install partitions on the website, but if you don’t have the skills to level walls and create new ones, it’s better to turn to specialists.

If desired, even brick wall You can insulate it with plasterboard, and at the same time level the surface.

Moreover, it will not take so much time, and sound and heat insulation will increase significantly. GKL sheets will also be appreciated by those who build a house from timber, because in order to retain heat, it is enough to insulate the walls using these materials to make the house cozy even in winter.

Cost calculation and material selection

Different types of edges are very convenient for bringing to life any design ideas, so when choosing a finish, be sure to check the differences.

After making the calculation required quantity finishing material, install a metal profile, after which the plates are attached to the profiles using ordinary self-tapping screws. After this, all seams are sealed with a special putty and, if necessary, plastered or covered with other finishing material.

Don't skimp on materials, buy them highest standard. If you wish, you can always clarify not only required quantity material, but also its cost.

When choosing a material for finishing the premises, you can choose different kinds, for example, use drywall or plywood as the main surface for the walls. The first option is the most common due to its qualities and cost, the second is used less frequently, but is more durable.

Drywall or plywood. materials have their advantages and disadvantages

Another principle of use is to mount drywall on plywood, and in this case it will be possible to significantly strengthen the walls. It is especially important to carry out such cladding of walls and ceilings in dachas, where veneer sheets are often used as cladding for rooms.
So, how to install according to the “plasterboard on plywood” scheme, and is it possible to use the latter as room decoration?

Both types of material have mass positive qualities. When mounted on walls, plywood allows you to create smooth surfaces that are more durable than plasterboard sheathing.

Finishing a room with plywood - practicality, warmth, reliability

At the same time, gypsum board allows the finishing of walls using various decorative materials: tiles, textured or Venetian plaster, painting, wallpaper and others. But there is one drawback, which is more of a feature - drywall does not resist moisture very well, because the base of its filler is gypsum.

Finishing a room with plasterboard - creating a design, many finishing options, visual extension premises

By the way, plywood sheets react very sensitively to changes in humidity in the room. Moreover, having accumulated moisture, the sheets will significantly change their shape. Once wet, plywood tends to swell and warp.

However, if the house is wooden, then it is quite acceptable to use plywood as a leveling finishing material, as well as for assembling partitions.
And of course, as an option, for restoration of old plywood sheathing or strengthening plasterboard wall can be mounted directly on gypsum board veneer sheets. What issues will this type of finishing solve:

Initially sheathing the frame or wooden sheathing sheets of plywood can eliminate shortcomings made when assembling the base, and also make the entire structure much stronger.
Sheathing a room with plywood hides surface imperfections
Restore old plywood trim by attaching sheets of drywall to it. In this way you can protect the plywood sheathing from moisture.
Old plywood trim can be covered with plasterboard or dismantled
Use plywood to strengthen the frame itself, making the entire structure more rigid.
Make walls more durable for hanging various elements furniture and household appliances.
Plywood makes the wall structure strong; carry a suspended load on it

If you have to choose whether to sheathe your house with plywood or plasterboard, then the best option will be the first. If there is plywood sheathing in normal condition, it is quite acceptable to finish it with gypsum board. How to do this and what is required for this?

How to attach drywall to plywood

Of course, you can completely and radically restore walls covered with plywood by completely dismantling the material, assembling the frame and then laying drywall. Frame technology installation is the most reliable and proven.

The metal frame for drywall is a rigid structure

However, if the walls have slight differences, it is quite possible to use frameless technology for attaching drywall to plywood. What does using this method give:

Firstly, the repair estimate will be significantly reduced, since the costs of purchasing profiles and other metal fittings for the frame are eliminated.
For frameless method no need to purchase profiles and components
Secondly, the area of the room will not be reduced so noticeably (especially important in small rooms), because the plasterboard sheets will be glued almost flush to the load-bearing surface.
Thirdly, on your own frameless installation It’s quite simple, the surface is prepared, an adhesive is applied to the sheets and the plasterboard is glued to the wall.
For the adhesive method, various mixtures and adhesives are used

It is worth remembering that fastening plasterboard sheathing without sheathing or frame it is possible on walls with differences not exceeding 50 mm. Otherwise, a foundation will be required.

In what ways can you mount gypsum boards on plywood without resorting to assembling the base:

The most reliable way is to use self-tapping screws. The fasteners will need an appropriate length so that the sheet is securely fixed.
Wood screws
The second way is to use glue. When installed on brick or concrete walls Perlfix gypsum mounting mixture is used. However, it is not entirely suitable for wood; it is best to use liquid nails or polyurethane foam.
Using glue or polyurethane foam for installing drywall to plywood

When attaching drywall to plywood using the adhesive method, it is worth additionally securing the fasteners with several self-tapping screws!

When assembling the frame, you can strengthen the walls if you first cover the base with plywood sheets (or OSB) and then cover it with plasterboard on top. This type of finishing is often used in the assembly and construction of shopping pavilions and other similar premises.

Frameless installation

If the differences in the walls are insignificant, then they can be directly sheathed with plasterboard. In this case, 2 methods are used. Each of them has its own characteristics and disadvantages. Installation with self-tapping screws is more durable, but there is a possibility of damaging the sheet if the distance between the fasteners is not observed. If you fasten screws frequently, the sheet may burst.

Correct fastening of drywall to plywood with self-tapping screws

The adhesive method is more loyal, but if the room has sudden temperature changes, the plasterboard may lag behind the base.

Method of attaching drywall to plywood with glue

Installation with self-tapping screws

It's more reliable way than using just adhesive mixtures. Even a canvas can be attached to a gypsum board fixed in this way. stretch ceiling.
Self-tapping screws are purchased phosphated (black), their length should be sufficient to connect the drywall with plywood sheathing and the wall of the house itself.

Phosphated wood screws

Initially, you need to carefully inspect the surface of the plywood sheathing for damage and unevenness. If there is fungus or mold, as well as swelling, they need to be eliminated and the damaged areas restored.
It is imperative to treat the plywood with antiseptics to avoid damage by fungus. You should also use moisture impregnations used to protect wood.
Impregnation for wood against moisture and bug damage
If wiring is being laid, it must be laid in grooves made in the plywood sheathing. But it will also be required enclose the cable in a protective corrugated pipe. It is imperative to make conclusions for switches, sockets and junction boxes.
The plasterboard sheet is laid on pads with wooden slats opposite the installation site. After all the measurements, they lift it, screw the screws first into bottom corner on the right, then moving upward in increments of 250-300 mm. Next, screws are screwed in along the edge at the bottom and top, and then to the left. Additionally, add a few pieces in the middle of the sheet.
Fastening plasterboard sheet with wood screws

Glue method

It's pretty quick way align the wall cladding. Be sure to combine glue and screws for reliable fixation.
As an installation adhesive composition It is better to use “liquid nails”.
Frame method implies the use classical scheme: assembly of the frame, covering it with plywood (you can also OSB boards) and further finishing with gypsum panels.

Installed frame and further covering it with plasterboard

First, the surface of the plywood must be cleaned of the old finish and damaged areas restored. Carefully sand the sheathing sheets to improve adhesion to the gypsum board.
Cleaning plywood from old wallpaper
As with fastening with self-tapping screws, required condition- sheathing processing protective compounds for wood, antiseptic.
After preparatory work, a sheet of plasterboard is laid on pads made of bars opposite the installation site.
“Liquid glue” is applied to the back of the sheet using a construction gun, first along the perimeter and then in the middle.
The sheet is lifted, pressed tightly against the wall, tapping and adjusting all areas to be even. While the glue dries, the sheet must be supported with timber stops.
The final stage - plasterboard sheets are additionally secured with several screws around the perimeter, corners, and in the middle.
The support is used in the adhesive method of gypsum plasterboard

GKL can be glued directly to the sheathing if there are small differences in the walls. If the difference reaches 50 mm, you must first attach cut strips of plasterboard 100 mm wide to the plywood sheathing using self-tapping screws. These pads are positioned to provide a flat surface for smoother gluing.

In the finishing of premises, for rough cladding of the surfaces of the floor, ceiling, walls, 2 methods are used - “dry” (installation on the plane of OSB, chipboard, SML, plywood, gypsum board and gypsum fiber board) and “wet” (plastering, pouring screed, using specialized building mixtures). IN modern renovation The “dry” method is the most preferable, since it is less labor-intensive, easy and much more economical. Since the appearance of the corresponding bases on the domestic market, standard plastering with concrete and putty solutions has almost completely ceased to be used.

Due to their low cost and other positive properties, the most popular materials are plasterboard, plywood and gypsum fiber sheets.

But what is the difference between them and what is better - gypsum fiber board, plywood or plasterboard, given the same scope of application and composite structure of each?

Drywall. Features and Applications

Drywall is a composite three-layer material, consisting in the middle of modified gypsum, covered on both sides in a cardboard shell, depending on the impregnation, moisture-resistant and (or) fire-resistant. Also, various fire-resistant and antihydrophobic components are added to the core itself.

This is how it exists:

Regular - gypsum board;
Moisture resistant - gypsum plasterboard;
Fire resistant - GKLO;
Fire- and water-resistant - GKLVO.

Used for several purposes:

To create a smooth, uniform surface. Most often, plasterboard is used to cover walls, ceilings, and less often the floor due to its high fragility, however, floor blocks are still produced for rooms with light loads;
To level the plane, in this case a frame made of metal profiles or wooden sheathing;
During the construction of interior partitions;
To mask communications;
As facing covering frame used for intracavity insulation and sound insulation;
For the formation of decorative and useful structures - arches, niches, shelves, cabinets, multi-level ceilings.

Advantages of gypsum plasterboard

The main advantages of plasterboard in interior decoration:

Plasticity and the ability to create concave structures, arcs, using a bending machine, needle roller or cuts
A light weight
Possibility of quick installation/disassembly and ease of cutting
Hygroscopicity
Low cost
A large selection of subsequent cladding - painting, tiling, wallpapering and so on
Possibility of purchasing laminated gypsum board sheets that do not require finishing and puttying, as well as plasterboard blocks combined with insulation

Disadvantages of drywall

Along with the positive qualities, gypsum board has the following disadvantages:

Low resistance to direct moisture, even with moisture-resistant cardboard treatment
Fragility and low strength of the material
Impossibility of using nails during installation, while the composite holds perfectly on glue or screws
Maintaining maximum air dryness in storage conditions
Instability to mold, mildew

GVL. Features and Applications

Gypsum fiber sheet, just like drywall, is made from gypsum, with the difference that it is also mixed with cellulose waste paper using a semi-dry method.

The areas of application for gypsum fiber board and gypsum board, as well as for plywood, are practically the same - cladding floors, walls, ceiling surfaces. It is much less suitable for arches due to its low ductility. Widely used in rooms with increased fire safety requirements.

It has 2 types:

Simple, general purpose- GVL;
Moisture resistant - GVLV.

Advantages of GVL

The positive properties of gypsum fiber include:

High resistance to direct fire;
Significant sound absorption;
Versatile application;
Possibility of cladding;
Frost resistance;
Biostability.

Weaknesses of GVL

As you can see, GVL differs significantly from drywall, despite the approximate similarity in composition. Gypsum fiber blocks have a lot of positive qualities, but they also have disadvantages:

Low ductility - if you choose what is most suitable for construction, for example, arches, plasterboard or gypsum fiber, the advantage will be with the first material;
Considerable weight;
High price.

Plywood. Features and Applications

Today, debates among finishers continue to debate whether plywood or plasterboard is the most suitable material for finishing, since these materials are considered the main competitors in finishing.

Plywood is also a sheet composite, which is made by gluing several layers of peeled birch, pear, maple, hornbeam or coniferous veneer with formaldehyde resins under significant temperature and pressure. It is often confused with chipboard, however, the difference between them is significant, both in the field of manufacturing technology and technical characteristics Oh.

There are 5 main types of plywood:

FBA - ordinary general purpose sheets;
FC - moisture resistant;
FSF - increased moisture resistance;
FOF - laminated, non-hydrophobic;
FBS - resistant to moisture, fire and frost.

Depending on the type of plywood, it is widely used:

In the cladding of walls, ceilings, floor coverings, building facades, as a rough or finishing coating;
To create some types of furniture;
When designing multi-level structures;
For box masking of communications.

Advantages of plywood

The advantages of using this material include:

More economical to purchase than chipboard;
High strength, unlike gypsum plasterboard;
Durability;
Biostability.

Disadvantages of plywood

The disadvantages of plywood include:

Flammability;
Poor resistance to moisture (when using non-moisture resistant general purpose material);
Low environmental friendliness due to the use of phenolic resins in manufacturing;
High price;
Low ductility;
Low sound absorption;
Complexity of cladding.

Differences and similarities of facing materials

All 3 types of cladding differ from each other in:

Manufacturing technologies and raw materials;
Advantageous parameters;
Technical specifications.

Similar features should be noted:

Sheet composite structure;
Ease of installation;
Possibility of use on different surfaces;
A variety of types according to the degree of moisture resistance and fire resistance;
Environmental friendliness.

Comparison of materials for dry wall cladding

In order to compare which is better - gypsum fiber board, plasterboard or plywood, it would be necessary to carry out comparative analysis the main technical characteristics of each. However, taking into account the difference in indicators depending on the type and trademark, doing this based on specific digital facts will be very problematic. These parameters depend on the needs of the consumer and the scope of application of the slabs.

However, we can highlight the main positive features and properties of each, as well as their disadvantages, using as an example a standard table of characteristics of general purpose boards - plywood, gypsum fiber board and gypsum plasterboard for interior decoration.

Thus we see that the greatest advantages Gypsum fiber boards meet the specified criteria. But this data is not critical. For example, where both gypsum fiber board and gypsum board are suitable for use, the second material will be preferable due to its lower cost.

And, in addition, every year new materials appear on the market, such as LSU - relatively cheap sheet material with excellent quality parameters. Therefore, when choosing, focus primarily on financial capabilities and application needs in a particular room.

How to secure wall cabinets in the kitchen on a wall made of aerated concrete?

When starting any renovation, it is often necessary to divide the plane, insulate the walls, level the surface or create elements decorative design as various types cabinets, shelves, ceilings. Plywood or drywall are best suited for these purposes. Before using the product, you need to know the features of working with it, as well as the goals and objectives of the repair. This will help in choosing the material and will make the structure durable and of high quality.

A sheet of plywood is a product made from several layers of glued veneer. The number of layers varies from three or more. This is a double-sided product containing a front and back side.
Basically, similar material is used:

as insulation in the aircraft industry and shipbuilding;
in the manufacture of bushings for bearings;
as a floor covering under laminate or parquet, giving the effect of isolation and leveling.

This is what 10mm third grade plywood looks like

Plywood can be divided into the following grades:

E (prestigious variety);
I grade;
II grade;
III grade;
IV grade.

Plywood different varieties

When designating the grades of material, the manufacturer notes both the front and back base. For example, E/I, I/I, I/II and so on.

Briefly characterizing the first grade of material, one can note in its composition pin, healthy and falling knots, and there are also small flaws in the wood, up to 5%.

Grade II contains more defects, each next view has even more of them in raw materials.
Today there are the following types of plywood:

The scope of plywood is extensive. It is used:

Plywood or drywall - which is better?

Sheathing can be done using either plasterboard or plywood. It's up to you to decide what's best. Before choosing which material is better to use for the job: drywall or plywood, you need to decide what you want.

Plywood is more natural material, since it itself consists of birch veneer and glue, which holds all the layers of plywood together. Exists a large number of varieties of plywood, one more stable and durable, the other more flexible. But overall the material is quite useful and practical. Plywood can be five-layer, three-layer or simply multi-layer. In general, plywood is used to provide insulation in industries such as: aviation, shipbuilding. In addition, it serves as a material for bushings for bearings.

As for drywall, its materials cannot be called environmentally friendly, because... its surface is a cardboard sheet, and the inside is filled with gypsum dough with various chemical additives.

Features of both types of materials

Also, when determining: drywall or plywood, take into account other features of these materials.

The only and main drawback plywood is deformed due to any type of moisture. Therefore, using this material it is better to check the humidity of the room. Although plywood is well suited for flooring as well as extensive installations.

Drywall, of course, has more advantages: it is resistant to moisture, suitable for the construction of partitions or ceiling cladding, in addition, it is excellent for quick installation.

Debates regarding which is better: plywood or plasterboard are ongoing among builders. Some say that you simply cannot find a better material than drywall. It is moisture-resistant, difficult to ignite, and in addition, profiles for it can be easily found. It is easy to use and quite cheap.

Those who fight for environmentally friendly building materials come to the defense of plywood. Perhaps plywood is a little more expensive than drywall, but it is made from natural materials. In addition, the strength of plywood has not been in doubt for many years, and drywall, in turn, is a rather fragile material in this sense.

In general, what is better: drywall or plywood is up to you to decide. For those who are more concerned about the environmental friendliness of their premises and the strength of materials, plywood is suitable, but for those who prefer cheap and easy-to-handle material, drywall is more suitable.

What is your opinion? Who prefers what, preferably with comments and experience of use
