What is stronger plywood or mdf. Question: What is more resistant to water - chipboard, MDF or plywood? The technology of subflooring from sheet materials

Sheet materials made on the basis of wood veneer or shavings are very often used for subflooring, leveling the surface under fine finish as well as for sound and heat insulation. At the same time, you often have to decide: which is better - plywood or chipboard? Let's try to answer this question.

To do this, you need to understand how and what these materials are made of, what properties they have and how they behave during operation.

Features and characteristics of materials

Composition and structure

Both plywood and chipboard are made up primarily of wood. But the first material is more natural, contains less glue.

The main difference between plywood and chipboard:

Plywood is layers of natural veneer of not the most expensive types of wood glued together: pine, spruce, birch. There can be three or more such layers, the thickness of the material depends on their number.
Chipboard consists of wood waste - sawdust and small chips mixed with glue and pressed into sheets.. It is clear that much more glue is required for its production.

Features and Benefits

To answer the question of what is better for the floor - chipboard or plywood, let's compare the characteristics of these materials.

Aesthetically plywood is more attractive. In some cases, it is also used as a finishing coating, covering it with paint or varnish.

Chipboards, even treated with special compounds or painted, have poorer moisture resistance. Unlike plywood, they do not take their original shape after soaking with water.
Chipboard is less resistant to abrasion, under load it can crumble over time. In addition, it holds fasteners worse - screws and nails.
But the advantages of chipboard include better bending strength than plywood, higher heat and sound insulation properties.
It is also important to take into account such characteristics of materials as price. For chipboard, it is much lower.

And yet, none of these materials has sufficient moisture resistance, and with constant exposure to moisture, they can rot and become a breeding ground for fungus and mold, leading to damage. finish coat. Therefore, it is better to use them in dry heated rooms.

Advice. For subfloor installation in wet rooms, OSB is more suitable - oriented strand boards, which are highly moisture resistant.

As for ease of installation, both materials are easy to lay with your own hands using standard tools. home master. into fragments desired shape and size.

Attention! When sawing chipboard, fine toxic dust is formed, so this should be done using a respirator or other protective equipment.

Based on the above information, it is difficult to make an unambiguous conclusion that it is better for the floor - plywood or chipboard. Everyone can independently evaluate the advantages and disadvantages of these materials and decide which one to use.

The technology of subflooring from sheet materials

Sheet materials can be laid on the old coating (plank floor, linoleum), on floors aligned with a screed or on logs. In the first two cases, in addition to fastening with screws, glue is used.

Screed flooring

Cement strainer done to level the surface. To do this, using a level around the perimeter of the room, a line is drawn on the walls, which will serve as a guideline for the height of the screed.

Then, bars are laid on the base, forming a grid of squares with a side length of about 1 meter. Their thickness should be slightly less than the thickness of the future screed.

Next is being prepared cement-sand mortar in a ratio of 1:3, which is poured into the cells of the grid and smoothed.

Note. To prevent the screed from cracking, it is necessary to ensure that a certain level of humidity is maintained during drying. To do this, it is covered plastic wrap and leave for 7-10 days.

After the solution dries, the instruction requires that the surface be primed bituminous mastic and let it dry. After that, you can start laying the subfloor.

The sheets are laid on a surface smeared with glue with a slight indentation from the walls and with a gap between them of 2-3 mm, necessary for temperature and humidity expansion. They should be laid out with offset joints: the corners of four sheets should not join at one point.

After laying chipboard or plywood on the floor, it is drilled and screwed to the base, first in the center, then around the perimeter.

Laying on lags

This method is less labor intensive and more environmentally friendly. If necessary, insulation or soundproofing material is laid between the lags.

However, thicker and stronger sheets should be placed on the logs to avoid their deformation. Which is stronger - chipboard or plywood? It depends on the thickness of the sheet and the distance between the lags.

For example, 12 mm plywood can be placed on a solid base, and at least 20 mm on logs, provided that the distance between them is no more than 40 cm. Chipboard thickness should also be 18-22 mm.

Sequence of work:

Draw a lag laying diagram depending on the size of the sheet material (see also the article). The joints of the sheets should fall on the center lines of the log. When doing this, take into account the shift of the sheets to offset the seams. You should get a grid with a cell size of 30-50 cm.
Lay longitudinal logs on the floor and level them using spacers. Fasten.

Attention! The distance between the wall and the extreme lags should be no more than 30-40 mm.

Mark the position of the transverse logs and attach them to the longitudinal nails driven in obliquely.

Lay the first sheet in the corner of the room, stepping back from the walls by 10-15 mm. In order not to stray from the center line when attaching to intermediate lags, mark the edges of the sheet with a pencil corresponding to the middle of the bars, and connect them with a straight line. Screw the self-tapping screws along these lines in increments of 100-150 mm, sinking the caps into the body of the material. Then fasten the sheet around the perimeter. It is best to use an electric screwdriver.
Mount the rest of the sheets in the same way, leaving a gap of 2-3 mm between them. If it is not there, the floors may begin to creak over time.

When using grooved sheets, a gap is not necessary. In this case, the grooved joints are lubricated with glue and sealed by padding each other with a mallet.
Do not forget to move the sheets to prevent four seams from crossing at one point, and leave a gap between them and the wall. Subsequently, they will be closed with a plinth.

It remains to be said that when laying in rooms where an increase in humidity is possible, sheet materials must be covered with drying oil or other protective agents before laying. If the room is dry, then in terms of cost savings and ease chipboard processing on the floor is better than plywood.

Conclusion

In any case, the homeowner has to make a choice in favor of one or another material or method of its installation, taking into account their own capabilities and requirements for coverage. The above information will only help you decide. And in the presented video in this article you will find additional information on this topic.

Plywood

Wood has been used to make furniture since ancient times, but it was a time when wood was available in abundance as wood became scarce and plywood was invented for those who couldn't afford teak, walnut or mahogany furniture. Plywood is made from wood, but every piece of wood is used to minimize the loss of wood. Plywood has many advantages such as a variety of sizes and thicknesses. It can be easily painted or laminated in any color or pattern. Plywood production minimizes wood waste, but does not eliminate it.

MDF

MDF is an abbreviation for medium density fibreboard. Since the scarcity of wood spurred the invention of plywood, MDF is another product that has been invented as a substitute for wood. MDF is made up of small pieces of wood that are broken into wood fibers and then compressed into hydraulic press at very high pressure in the form of a board. MDF boards are made in various thicknesses so that they can be easily used in various industries. These plates are very smooth surface and furniture from them is very high quality in terms of attractiveness. MDF is easily laminated various forms and colors or dyed as you choose. MDF boards are made from wood fibres, hence they have very little screw-driving potential.

Both plywood and MDF are made from wood and are used to make home and office furniture. Both of these products are widely used by furniture manufacturers around the world and provide flexibility in their work. The main difference is that plywood is made from solid wood while MDF is made from wood fibers. Plywood is available in larger sizes than MDF boards. Plywood is much better suited for nailing and threading than MDF. For MDF fasteners a certain technique is used, and plywood can simply be nailed or screwed. MDF has a better surface for making furniture than plywood.

Summary:

1. Plywood is made from solid wood while MDF is made from wood fibers.

2. There is wood loss in plywood production, and wood loss is zero when MDF production it is also made by mixing various wood fibers.

3. Plywood comes in larger sizes than MDF boards. But MDF is more attractive and you can paint it any color you like.

4. Plywood can be simply nailed or self-tapping, when making furniture from MDF, a certain fastening technique is needed.

5. Plywood furniture is stronger than MDF.

Worldwide, MDF is rapidly replacing plywood in the furniture industry. The shortage of wood in the coming years will be completely eliminated by plywood and MDF boards. The biggest advantage is that in the production of MDF there is zero wood waste, it is also possible to mix wood fibers of different species, while plywood is made from one species and at a time. Both plywood and MDF are used in furniture, but MDF is now mainly used for furniture production, and plywood is used as a packaging material because it is stronger than MDF board. MDF is an environmentally friendly product, if you care about the environment, you'd better choose MDF for making furniture, not plywood.

A little discussion about furniture materials: chipboard, MDF, plywood, furniture board, lumber, veneer.

Choice furniture materials may seem complicated. And yet, with an understanding of the essence of the issue, the choice will always be elementary. About this video. Watch, ask questions, comment...

Today I want to reveal the following question: What is the difference between the materials used for the production of furniture? To date, there are the following materials: chipboard, MDF, plywood, furniture board, lumber, veneer. Let's talk specifically about each of them.

Chipboard is an abbreviation of the full name: chipboard. A modern composite material obtained by pressing wood particles (sawdust and shavings), formaldehyde resins are used as a binder. Interesting fact from Wikipedia: “Particleboard appeared in the 1940s in the USA ( English Chipboard) for temporary furniture for American refugees.” An appropriate explanation, which once again reminds us why and for whom furniture made of chipboard was originally invented.

Consider further operational chipboard characteristics. One (and probably its only positive characteristic) is stability. Chipboard products retain their shape, color and dimensions in normal room conditions. This is a dead material and, in comparison with wooden furniture, does not require compliance relative humidity air, unless completely filled with water.

The next indicator that directly affects the life expectancy of furniture is strength. Whoever had furniture made of chipboard (most likely each of us) knows how fragile this material is. Despite the external solidity, which is created by a thin layer of plastic ( laminated chipboard), inside it consists of sawdust and shavings. And in terms of their density, chipboard may differ, which is immediately visible on the saw cut. Loose chipboard will not last you even a year: loops will immediately fly out of it, shelves can break from the weight of books, chips appear, etc. Such furniture is beyond repair, do not even hope! If you are lucky and you have purchased furniture made of higher quality dense chipboard, then it will last you a maximum of 10 years. But only on condition correct operation: do not hit on corners, do not scratch or pour water. If you want to disassemble and reassemble such furniture, then keep in mind that the third time you will not be able to screw in the screws.

But these are only the visible disadvantages of chipboard furniture. An important environmental indicator, which is hidden, but directed affects the health of consumers. The binder resins are to blame for this, which emit formaldehyde harmful to humans. Maximum allowable emission harmful substances determined sanitary standards. But do all manufacturers comply with these requirements? Low-grade cheap boards sometimes exceed MPC up to 40 times. Abroad (in Europe and the USA), plates of this class are no longer produced, and for the production of furniture it is allowed to use only ultra-safe plates of the Super E class. Particularly hazardous to health New furniture from which active formaldehyde particles have not yet weathered. Therefore, when buying, you should especially pay attention to pasting all, even invisible from the outside, ends of furniture. Use your sense of smell and sniff. Furniture made of chipboard with a high concentration of formaldehyde is caustic bad smell. But often, what is worth as a sample is not always what will be brought to your home.

What is the difference between MDF (Medium Density Fibreboard) from chipboard? It is classified as a less toxic material, because the plates are formed by dry pressing of fine wood shavings at high pressure and temperature. Melamine-modified urea resins are used as a binder. This ensures very low formaldehyde emissions comparable to those of natural wood. Therefore, it is considered a more environmentally friendly material and is widely used in the manufacture of furniture. The strength of MDF exceeds chipboard by about 2 times, slightly increasing the life of the furniture. Unlike chipboard, MDF is a moisture-resistant material, especially if it is varnished and enamelled. Such furniture is practical to use in the bathroom, where the humidity is constantly high.

In addition, MDF can be faced with plastic, film or veneer. Diversity color shades and effects (shine, mother-of-pearl, metallic, etc.) - impressive! In addition, with the help of special equipment, parts from MDF can be given any shape, to make radius doors.

Each coverage option has its pros and cons. Therefore, initially it is worth thinking about the purpose of the furniture. In what form it is better to use MDF depends on where and in what conditions the future furniture will be located and what aesthetic requirements you impose on it. MDF in film, plastic or enameled looks like plastic - cold and lifeless. But covered with veneer - it is impossible to distinguish from wood at first glance. Therefore, very often commercial manufacturers use MDF in furniture where both wood and MDF are partially present.

Plywood- a traditional wood material, the likeness of which was found even in Ancient Egypt. Later, in Greece and Rome, craftsmen glued the rough wood veneer by hand using natural resins. industrial production plywood began only in the 19th century, which made furniture more affordable and at the same time increased its quality. Modern furniture plywood is obtained by gluing 3 or more sheets of special veneer using carbamide resin. Emissions of free formaldehyde from furniture plywood are negligible and comparable in their performance to natural wood. In Russia, birch veneer plywood is mainly used for furniture production. And for example, in the USA you can find cherry plywood, which in in large numbers grows in the northeastern part of the country. Plywood furniture has been produced since the end of the 19th century and has proved its right to exist. The pull-out strength of plywood fasteners is approximately equal to the strength of wood. The service life of plywood furniture reaches from 50 to 100 years. No wonder vintage samples of the 50s are already becoming a rarity and the subject of designer collections.

The first chairs bent plywood American designers and spouses Ray & Charles Eames began to be produced since 1941 and were very popular in the USA and Europe.

Due to its environmental friendliness and low cost, plywood furniture is a favorite subject modern interior. They make children's furniture out of it, kitchen sets, armchairs and a wide variety of designer furniture. Plywood can be used in furniture, keeping its natural birch color, or painted in any color, as well as veneered. The finish of the plywood ends depends on the design of the product. They can be left open or closed with a wooden edge, veneered, so that you can’t distinguish it from wood.

furniture board- This is a wood material obtained from planed wooden bars glued together in width and length. Made from solid birch, oak, beech, conifers different thicknesses and sizes. Due to its high strength and environmental friendliness, identical to solid wood, it has been widely used in construction, decoration and the production of wooden furniture. The furniture board has a characteristic external feature, by which it can immediately be distinguished from solid wood or plywood. A peculiar chess pattern of spliced bars is visible even in finished product which betrays its origin. Working with a furniture board requires a certain skill, since the material glued from the bars has internal stress. This can lead to deformation (warping) of furniture panel parts already in the finished product. The service life of furniture made from such a board is comparable to solid wood furniture, and is also subject to restoration and complete restoration.

Veneer- This thinnest sheet wood, the thickness of which does not exceed 3 mm. Natural wood veneer is obtained by thinly cutting a part of the surface from solid wood (plywood logs), which has been special treatment. There is currently large selection of veneers obtained from various types of wood: oak, birch, maple, cherry, beech, walnut, wenge, bibolo, gabon, etc. With different ends Sveta.

photo of the sideboard production report, the doors of which are decorated with oak veneer pasted with a classic rhombus.

The environmental friendliness of such furniture depends on the adhesives and varnishes used and lies entirely on the conscience of the manufacturer. You should also be aware that furniture using veneer requires compliance with certain microclimatic parameters of the room and does not like excessive moisture. Small defects on the surface of the veneer can be repaired. The pull-out strength of fasteners will depend on what is used as the base material: wood, plywood or MDF. The last option is completely unacceptable for me, because. has the lowest (no more than 10 years) service life and carries only the outward appearance of a tree, without actually carrying anything more.

The quality of lumber directly affects the durability of furniture made from it. The presence of defects in lumber, such as knots and cracks, significantly reduces its quality, violating the integrity and strength of the board. And high-quality lumber costs several times more than low-grade lumber. The quality of the resulting lumber is influenced by such factors as the felling season, the age of the tree, and even environmental friendliness, i.e. no toxic contaminants environment. good lumber really "worth its weight in gold" and furniture from it will be a real exclusive product at the most expensive price. Therefore, in the manufacture of wooden furniture, artisans often use such wood materials as plywood, veneer and furniture board. This reduces the cost of products and speeds up the manufacturing process, without compromising the performance of the furniture. A real connoisseur of wooden furniture is not scared away by horror stories about cracking And special conditions humidity. None of the above wood materials unable to endure what a tree can endure. My experience shows that even the most unfavorable storage conditions are not capable of permanently killing quality furniture from wood. The proof is the real process of restoration of the ancient desk, the restoration of which was a surprise even for the hostess herself.

If not wood, then which is better, MDF or chipboard? Thinking out loud about understanding sustainability and sustainability…

And what, the entrance is so wet and why the Firm will look for what is cheaper and what it has http://dspnd.ru/product/27.htm Advantages of the MDF board-http://articles.m-strou.ru/article_5119.... Strength. MDF boards are not inferior in strength to natural wood, so they can be used for the manufacture of both decorative and full-functional structures. Moisture resistance. The density of the plates and their homogeneous internal structure, as well as the protective outer coating, make it possible to increase the moisture resistance of products, which allows them to be wet cleaned without compromising quality. However, the use of MDF panels in bathrooms and swimming pools is not recommended. Decorative. The possibility of finishing with various materials (painting, lamination, veneering), as well as combinations various ways finishes (veneering and painting), allow you to get unique patterns to create exclusive interiors. Ease of processing. The density of MDF boards is 700-870 kg / m3, which makes it possible to process on milling machines and obtaining various reliefs: from simple ones - for furniture panels - to complex ones - in the production of 3D panels. Durability. MDF panels do not warp, crack or dry out from temperature changes. Thanks to special impregnations, they are not exposed to insect pests, fungus and mold. The decorative and protective coating does not require additional maintenance - tinting, varnishing, etc. Subject to the rules of operation, MDF products can serve their owners for several decades. PLYWOOD is a layered material consisting of sheets of peeled veneer glued together. Peeled veneer - a thin layer of wood of a given thickness in the form of a tape obtained by peeling a block on peeling machines. In this case, a cylindrical piece of wood (churak) performs a rotational movement, and a tool (knife) a translational movement in the direction of the axis of rotation of the material. Peeled veneer is made from birch, alder, aspen, pine, larch, cedar, oak, ash, beech, elm, linden wood. Peeled veneer comes out from under the machine knife in the form of a continuous strip of a given thickness and width. To give the wood the necessary plasticity, churaki are boiled in water heated to a temperature of 50-60 C before peeling. The veneer strip obtained as a result of peeling is cut with special scissors into sheets of a given format, which are then dried, cut, sorted. Plywood is considered to be made from the same type of wood from which its outer layers are made. Plywood has a number of advantages compared to lumber: it has almost equal strength in all directions; little warps and cracks; easy to bend and easy to carry; there are no through cracks in it; plywood sheets are big sizes. Plywood is a very promising material, which last years is increasingly used not only traditionally in furniture production, aircraft and shipbuilding, but also in construction, interior decoration. Widely used today as a basis for floor coverings under parquet, laminate, linoleum, carpet, being at the same time an excellent heat and sound insulation of the floor. The use of plywood in design gives an outlet to the volume, allows you to go into three-dimensional space, lighten the design, especially if it is something non-standard. Plywood is attractive for its environmental friendliness, all over the world, especially in Europe, plywood products are considered as solid wood products.

Hello, dear site visitors!

We would like to say a few words about the most common materials used for the production of "Rigid" furniture - cabinets (both built-in and cabinet), kitchens, wardrobe rooms, pedestals, etc.

First of all, it should be said that the main constituent parts furniture can be:

frame,
facade,
countertop,
accessories.

Housing Materials - Product Basics

Material No. 1 - chipboard

The vast majority of furniture cases in Russia are made of chipboard 16 mm thick, although there are other thicknesses, such as 18.25 mm. Chipboard is a Laminated Chipboard (the official abbreviation is LDSP, the most common abbreviation is LDSP, colloquially - chipboard, in professional slang - firewood). Principal device is a Particle Board consisting of glued together with high temperature wood shavings, on which a special decorative paper- impregnate. This paper (Impregnate) either imitates various materials - as a rule, wood of various species or some other materials, for example, titanium metal, or simply plain in different colors: white, beige red, blue, etc.

Chipboard not laminated (or polished) is not used for the production of furniture cases.

1 chipboard

2 chipboard

The price of laminated chipboard depends on the Thickness, Color, Texture (the surface may be different to the touch) and the pricing policy of the manufacturer. Prices

In the photo: Chipboard Egger white color with different textures.

For the manufacture of furniture, the laminated chipboard is sawn, and a decorative edge of various THICKNESS is glued to the ends, depending on the purpose.

In the photo: Chipboard 16 mm with PVC edging 2 mm thick

The material from which the edges are now made is plastic (or PVC-Polyvinyl chloride or ABS - Acrylonitrile butadiene styrene) with a thickness of 0.4 to 2 mm. Such edges are designed for application on special equipment. The previously common melamine edges, which could be glued with an iron, have practically gone out of use due to their lower consumer qualities.

Material No. 2 - MDF

MDF is, like chipboard, a glued board, only it is glued not from chips, but from wood “dust”.
MDF (MDF) - from English. Medium Density Fibreboard to refer to medium density fibreboard. The most common thicknesses are 16, 19 and 25 mm, as well as gluing from these plates.
The fundamental difference from chipboard - MDF is much more durable and dense - therefore, patterns can be applied to its surface by milling.

In the photo: MDF with milling

MDF is more expensive (more wood base, more binder) than chipboard, and tends to intended for subsequent surface treatment: painting, milling, gluing veneer, plastic, PVC film, etc. For this reason, laminated MDF of any color other than white is a rarity.

There is an opinion that MDF is a more environmentally friendly material than chipboard - this is a delusion.
The environmental characteristics of these materials are very close: both high-quality chipboard and high-quality MDF corresponding to the E1 class have equally low formaldehyde emission rates. To see this - read the Egger environmental brochure - see page 24.

Eco Brochure Egger
Eco Egger.pdf (1.61 MB)

Material No. 3 - furniture board, solid wood, plywood

Furniture panel, solid wood, plywood are also glued wood. In general, furniture made from a single piece of wood is a rarity in the modern world. The reason for this is number one - due to changes in humidity, a single piece of wood of large width (namely, this is what is needed for the production of the cabinet body) is prone to deformation, reason number two - a solid tree of large width is very expensive.

Material No. 4 - for the rear walls

For the rear walls, the most common materials are fiberboard, HDF, chipboard and, in the cheapest furniture, fiberboard.

A little more about each of these materials in ascending order of cost.

Fiberboard - Fibreboard is similar in composition to MDF, only the density is lower and standard thickness a little over 3 mm. This is the cheapest board material known to us, it does not have decorative finishes, but often has a persistent smell, which tends to accumulate inside your closet. This material will suit only the most undemanding consumers.

DVPO - Ennobled Wood-Fiber Board, colloquially - Hardboard. This is fiberboard, one side of which is painted and either imitates wood, or just plain color. Since the decorative layer of DVPO is applied using a technology fundamentally different from chipboard, their colors are different.

HDF - from the English High Density Fiberboard - high-density fibreboard. Roughly, this is a higher quality DVPO. HDF is produced by the same companies as chipboard, so some of the colors of HDF and chipboard are almost identical, but, alas, not all. The disadvantages of MDF are the cost close to chipboard and relative fragility.

Chipboard for rear walls is used in the following cases:

Back wall is not closed by the facade and its color must completely match the rest of the body parts. In this case, the thinnest plate, 8 mm, is most often used.
The product is located in the middle of the room - and its back side is visible. The back wall experiences high loads - in this case, chipboard with a thickness of 16 mm or more is used.

Facade materials

It should be noted that the facades are different according to the type of opening: sliding - for example, compartment doors made of aluminum profile and hinged, which affects their design.

From a structural point of view, facades can consist of a single material and be prefabricated, for example, filling from other materials is inserted into a profile from one material. Common Frame Materials − aluminum profile, a profile made of MDF and wrapped in PVC film.

The materials for the facades, consisting of a single material, and the materials for filling prefabricated facades are basically the same: laminated chipboard, painted MDF, both with and without milling, MDF covered with PVC film, MDF covered with HPL plastics, Mirror and glass, as simple and processed - matte, tinted, dyed, with a pattern, etc., decorative plastics and artificial leather.

1) chipboard.
2) Transparent glass and silver mirror (i.e. not tinted)
3) Glasses with Oracal color films
4) Facades made of MDF frame profile
5) MDF covered with PVC films
6) MDF coated with HPL plastic from Egger, Melaton, Arpa, etc.
7) Painted MDF matte
8) Painted MDF glossy
9) MDF veneered

Variants of materials from which countertops are made

If the furniture is not exposed to moisture, then it is chipboard or MDF, painted or veneered.

If the furniture is exposed to moisture, for example in the kitchen, then this is a countertop based on moisture-resistant chipboard lined with plastic, a countertop made of artificial stone or natural stone.
