Few of them modern people It will be difficult to say what the word chipboard means. Most of us have come across this material when choosing or assembling furniture - wood particle boards(just in case, let’s mention that this is the decoding of the mentioned abbreviation) are used in the production of furniture frames, shelves, doors and cladding elements. In our article we will talk about what types of chipboards there are and how they differ in their technical characteristics.
Basic parameters of particle boards
Despite the fact that at first glance all slabs of equal dimensions look approximately the same, in fact they differ in a number of parameters. The basic requirements for chipboard are contained in a special standard (GOST 10632-2007), according to which several different classes of these products are distinguished.
Chipboard varieties
Depending on the quality of surface treatment, three types of the material under discussion are distinguished:
Formaldehyde emission class
In the production of chipboards, phenol-formaldehyde resins are used, which can release highly toxic substances into the air that are harmful to human health. Modern technologies allow you to control the specific composition of these substances, therefore state standard Limits have been introduced on how much formaldehyde can be contained in a particle board composite:
- Class E1. The standard indicator is up to 8 mg per 100 g of composite. It is stated that this is absolutely safe dose, therefore, slabs of this class can be used in any premises, including furniture for children's rooms.
- Class E2. The permissible concentration is up to 30 mg per 100 g of material. Such sizes of impurities already exceed the permissible dose, so these panels are produced in small quantities and used in places where human contact is completely excluded.
There has long been fierce debate about the environmental friendliness of panels made from waste wood. Some authors argue that many manufacturers deliberately distort data about their products - after all, the level of formaldehyde or methanol emission into the air can only be measured in laboratory conditions.
In any case, before purchasing Chipboard is better approach the place where it is stored: if a persistent chemical odor is felt at a distance of a meter from the pack, it means that the content is most likely acceptable harmful substances it is exceeded.
Chipboard brands
The meaning of chipboard markings is determined by the above-mentioned GOST. In the generally accepted brand designation, the second symbol defines it. Depending on the mechanical properties, two grades are distinguished:
- P-A. High bending strength, high moisture resistance, low tendency to swelling and roughness;
- P-B. Weaker characteristics compared to brand P-A. However, the slabs grades P-B have more low price, which makes them widespread in construction: laying the base of the floor and walls under finishing, installation of floors, formation of formwork, etc.
Geometric dimensions of chipboard
The dimensions of the chipboard sheet are also specified in GOST 10632-2007. This document states:
- length gradation – from 1830 to 5680 mm – 18 standard values;
- width gradation – from 1220 to 2500 mm – 9 standard values;
- thickness gradation – from 3 or more with gradation 1.
It is easy to see that the linear dimensions of the chipboard are specified by a discrete set of values, and the thickness of the chipboard can be almost any.
The most popular thickness sizes are:
The weight of chipboard is determined by the dimensions of the sheet. The density of the material is almost always the same, so the weight is proportional to the area of the sheet and its thickness. For example, average chipboard weight 10mm thick, with dimensions 2750 x 1830 mm, is 37 kg.
Density of chipboard
One of the most common misconceptions is that the higher the density of chipboard, the better. In fact, this misconception goes back to the Soviet past, when the quality of particle boards produced was quite low due to improper processing of the chips used. In those days, the shortcomings of the technology were compensated for by the increased content of formaldehyde resin. And manufacturers proudly declared that the density of their chipboard is 750 kg/m 3 .
In fact, the main load-bearing element of a chipboard sheet is its surface. Only it is capable of holding fasteners; the inner layer is, by definition, very loose due to the characteristics of the material itself.
As evidence, we present the density indicators of slabs from the leading manufacturer - Kronospan:
It is easy to see that the thickest sheets with a thickness of 20, 30, 32, 38 mm have a density of less than 700 kg/m 3, which is quite enough to ensure very high quality.
Chipboard packaging
Often, when purchasing a large volume of chipboards, the question arises about how many m2 is the area of one sheet, how many sheets are in one pack and how much the sheet weighs. Of course, it all depends on what size each sheet is.
Let's start with the leaf area. The following table shows the breakdown of area values for the most popular sizes:
| Size | Leaf area | Sheet volume (chipboard thickness 10mm) | Sheet volume (chipboard thickness 18 mm) | Sheet volume (chipboard thickness 20 mm) | Sheet volume (chipboard thickness 38 mm) |
| 2440x1830 | 4.47 m2 | 0,045 | 0,080 | 0,089 | 0,170 |
| 2750x1830 | 5.03 m2 | 0,050 | 0,091 | 0,101 | 0,191 |
| 3060x1830 | 5.60 m2 | 0,056 | 0,100 | 0,112 | 0,213 |
| 3060x1220 | 3.73 m2 | 0,037 | 0,067 | 0,075 | 0,142 |
| 3060x610 | 1.87 m2 | 0,019 | 0,036 | 0,037 | 0,071 |
Now let's give the average weight of these same slabs:
| Thickness | Dimensions | ||||
| 2440x1830 | 2750x1830 | 3060x1830 | 3060x1220 | 3060x610 | |
| 10 mm | 26 | 29 | 33 | 22 | 11 |
| 18 mm | 33 | 37 | 41 | 27 | 14 |
| 20 mm | 60 | 67 | 75 | 50 | 25 |
| 32 mm | 86 | 97 | 108 | 72 | 36 |
Please note that the largest 32mm thick sheet in question weighs over 100kg. It can hardly be lifted by two adults. The weight of a thin chipboard, for example, ten millimeters thick, can easily be handled alone.
For industrial shipment, chipboards are packaged in bundles. The number of sheets in a bundle depends on the thickness of the chipboard and is selected in such a way that the mass of the bundle does not exceed the carrying capacity of industrial equipment. Here are some numbers showing how much a pack of chipboard weighs:
That's all the basic technical chipboard characteristics can be considered mentioned. There are, of course, special products, including moisture- and fire-resistant models, boards with a high formaldehyde content and other exclusive models, but they are rarely produced. Choosing the right brand particle board, you get reliable and inexpensive material for the production of a wide variety of designs.
The furniture industry has recently increasingly used another material instead of the usual wood - chipboards (chipboards), which have several varieties and are characterized by good performance indicators.
The use of chipboard is not limited to furniture production; it has become widespread as a relatively lightweight and cheap material universal application. What are the types of chipboards? standard sizes and areas of its use - this is what our article is about.
Reasons for the popularity of chipboard
The chipboard production technology is quite simple: using a special adhesive composition, natural wood shavings are tightly connected to each other. Low-value wood waste is used as the main “ingredient” coniferous species, therefore such production is very justified from an environmental point of view.

Often such designs are limited in width to two thin sheets of laminated film. The thickness of the formed layer of the slab can be 8 – 38 mm. The most popular are chipboards with a width of 16-18 mm.
Advantages of DPS:
- Ease of processing.
- Low cost.
- Light weight.
- Good strength.
- Uniformity of structure.
- Large selection of chipboard colors.
All these indicators make the slabs very popular in various fields of construction. 
Such plates also have disadvantages. They mainly concern the quality of the binders used. If the excess of formaldehyde resins is greater than the average, the use of such materials in residential premises is highly doubtful. To avoid harmful effects on the body, slabs should be selected according to their safety class, without using chipboards of inappropriate parameters.
Classified by surface type following types Chipboard:
- Untreated chipboard used exclusively for black finishing of premises, if in the future this area is planned to be sewn up finishing material. The surface is rough to the touch, the texture of the used shavings clearly appears on it.
- Sanded plate It is more widespread and is used even in the furniture industry, but not in front surfaces. From the outside, the plane of the slab is smoother, but its structure is also clearly visible. Sanded chipboard is often coated with a special water-repellent compound to be used in areas high humidity eg for bathroom ceilings.
- Keyed chipboard is an outer covering in the form of an imitation of expensive tree species. Such slabs look more attractive and are highly valued for interior decoration.
- Laminated slabs instead of wood they are covered with a layer of impregnated paper base. Such a surface is short-lived and highly susceptible to mechanical stress. When choosing laminated chipboard, care must be taken to ensure that the surface does not come into too much contact with surrounding objects and chemicals.
- Laminated chipboard Unlike the types described above, it has excellent strength and performance characteristics, as well as greater durability. Process produced by laminated chipboard involves coating a paper base with a special film, which, under the influence of high temperatures and pressure, tightly adheres to the surface, forming a monolithic layer. Laminated chipboards are widely used in the furniture industry; the abundance of colors and patterns creates the illusion expensive materials for a significantly lower cost.
Recently, wood-based panels lined with special plastic coatings and polymer films have also appeared. This allows you to increase the moisture resistance of the material, but from a practical point of view, such slabs are very fragile. The quality of such chipboards will vary greatly depending on the manufacturer, so before purchasing it is advisable to check all hygiene certificates that allow the material to be used indoors.
Chipboards are an excellent option for an environmentally friendly analogue of wood. There are enough varieties of chipboard to choose the right brand for any kind of rough work. finishing works, furniture manufacturing and other household and industrial needs.
The slabs are produced in a sufficient range of shapes and colors; the most popular is the thickness of 16 mm, which allows us to produce furniture of good strength and high performance characteristics. Choosing chipboard for interior works, you should definitely pay attention to the labeling and composition of the material.
Furniture manufacturers who use chipboard as the main material pay attention not only to the size of the chipboard and the thickness of each sheet, but also to its weight. When indicating the quality characteristics of a particular brand of wood boards, the manufacturer always provides data on the weight of the product. Most often, weight is indicated in kilograms per 1 square meter slabs Accordingly, how much does it weigh chipboard sheet, it will be quite easy to calculate.
Factors affecting the weight of chipboard
The total mass of particle board depends on several factors, among which are:
- the type of wood used as raw material in the production of chipboard. Each type of wood has a unique structure and fiber density, which causes differences in the weight of shavings and sawdust from pine, linden, oak, etc.
- compaction density of wood pulp during the process of board formation. The more air remains between the wood particles mixed with the glue, the lighter the final weight of the board will be.
- the size of each individual sheet of chipboard - that is, the number of square meters in one slab. The shorter the length, width and thickness of the slab, the less its total weight.
Chipboard weight from leading manufacturers
Analyzing the mass of wood boards, it can be noted that each manufacturer, depending on the characteristics of its technological process, offers products of different weights. In the table below, we have tried to systematize information about the mass of different formats of wood-based panels from leading manufacturers.

The table shows that the weight of slabs with the same format can differ significantly due to differences in thickness. In addition, wood boards of the same thickness, but made by different manufacturers, also have different mass per 1 square meter.
Thus, the indicator of how much a chipboard sheet weighs depends on many reasons. Experienced furniture manufacturers often rely on its value when assessing the quality of a batch of chipboards. Too much weight of the slab may indicate a violation of the drying technology in the production of chipboards, and too much light slab may turn out to be fragile and brittle.
IN last years The demand for laminated chipboard has increased significantly, which is used not only in the manufacture of furniture, but also in construction and repair work– from rough finishing of walls to installation of decorative flooring. The market offers a huge selection of laminated chipboards: sheet sizes, colors, textures and types are presented in a wide range. This article will tell you how to determine the optimal price-quality ratio, and what main characteristics you should pay attention to.
LDSP is a type of well-known particle board (chipboard). This material has long been in deserved demand among domestic and foreign builders and furniture manufacturers.
Among the main advantages of chipboard is its low cost. Due to the fact that production waste (shavings and sawdust), or even simply crushed substandard trunks, is used to make chipboard, its price is several times lower than for MDF or natural wood.
Other undoubted advantages of this composite material are its strength, ease of processing, resistance to mechanical damage, as well as a wide variety of types, which significantly increases the scope of its application.
Among the disadvantages of chipboard is insufficient moisture resistance. Under the influence of water, the slabs swell and deform. The same thing happens when high temperatures. In addition, the resins contained in them, when evaporated, can cause significant harm to human health. This composite material is also not very flexible and can crumble when trying to reinstall the fastener.
Types of chipboards and areas of their application
Depending on the level environmental safety There are 2 classes of chipboard – classes E1 and E2. Class E1 chipboard is considered the safest, as it contains less formaldehyde resins. The content of harmful substances in E2 class boards does not allow their use in the manufacture of children's furniture. Moreover, in recent years there has been a gradual reduction in its production in EU countries. In Europe, there is another class of chipboards - Super E. Materials of this class are absolutely safe, but they are extremely expensive.
Helpful advice! Experts emphasize that it is better to buy laminated chipboard sheets made according to European standards, known for their strictness in safety matters. environment and human health. The content of formaldehyde resins in them is several times less than that of slabs manufactured in accordance with domestic or even American standards.
Externally chipboard type divided into 3 varieties. First grade slabs are made only from high quality raw materials, they have no defects, and final stage During production they are covered with a special decorative film or veneer. This variety used in the manufacture of furniture.
For slabs of the second grade, cladding is not required; minor scratches or chips along the edges are allowed. Third grade chipboards are often made from raw materials containing foreign inclusions or from wood bark shavings; they have visible defects - chips, cracks, unevenness. The last two varieties are used mainly in construction - as rough finishing, flooring, leveling ceilings and walls, and making formwork.
In addition, chipboards are:
- untreated (they are used for rough finishing of premises);
- polished (used in the manufacture of furniture, but only for elements hidden from view);
- laminated (specially treated paper is used as a covering);
- veneered (on both sides the sheet is covered thin layer natural wood, which gives them a decorative appearance and allows them to be used for the front surfaces of furniture and for interior decoration);
- laminated (a chipboard sheet is covered with a polymer film).
Features of laminated chipboards
Laminated chipboards are produced exclusively from high-quality polished chipboards in accordance with GOST 10632-2007. They are free from the disadvantages inherent in other particle boards: durable, not afraid of steam, mold and moisture, chemical and mechanical impact, and a special melamine film and edge finishing significantly reduce the level of hazardous fumes and increase the wear resistance of the material.
Thanks to these characteristics, laminated chipboards can be used for the manufacture of furniture and interior decoration, including kitchens, hallways and bathrooms, wardrobes, office and children's furniture, and as flooring.
Laminated chipboards are presented on the market in a huge number of colors and textures, allowing you to imitate any material, including stone, marble, metal or fabric, and fit into any color scheme or interior style at a very modest cost.
Laminated chipboards do not require further processing or painting. For the manufacture of furniture facades and tabletops, it is enough to cut the purchased sheet of chipboard in accordance with the provided dimensions and edge the edges.
Important! It is necessary to treat the edge not only to increase the wear resistance and appearance of the material, to protect it from moisture and steam, but also to prevent the evaporation of harmful substances.
However, this is the main disadvantage of this material– the need for a special machine for sawing laminated chipboards and edging them. However, currently any hardware store or a furniture manufacturing workshop provides a service such as cutting laminated chipboard according to customer sizes.
Another disadvantage is that due to the crumbling edge, such slabs are also not suitable for creating curved contours and complex carved elements.
Chipboard: sheet size. Basic indicators of length, width and thickness
Standard dimensions of laminated chipboard sheets are regulated by GOST. In accordance with this standard, the width, length and thickness of the slabs are determined.
Main dimensions of laminated chipboard
There are 18 standard lengths: 1830, 2040, 2440, 2500, 2600, 2700, 2750, 2840, 3220, 3500, 3600, 3660, 3690, 3750, 4100, 5200, 5500 and 5680 mm. In this case, the permissible length inaccuracy is ±5 mm.
The width of laminated chipboard slabs is determined by 9 indicators: 1220, 1250, 1500, 1750, 1800, 1830, 2135, 2440 and 2500 mm. As with length, the permissible error does not exceed ±5 mm.
The thickness of laminated chipboard ranges from 3 to 38 mm with an acceptable inaccuracy of ±0.3 mm.
It should be clarified that, depending on the capabilities of the equipment, each manufacturer produces several basic sizes of chipboard, but the following are considered the most popular on the market:
- 2800x2620 mm;
- 2800x2070 mm;
- 2620x1830 mm;
- 2500x1830 mm.
Thickness of laminated chipboard sheets
Their strength and ability to resist loads, and therefore their scope of application, directly depends on the thickness of the laminated chipboard. It is important to remember that heavy thick slabs are very durable, but thin laminated chipboards bend without being deformed.
Most often, the thickness of laminated chipboard ranges from 8 to 38 mm. 8-10 mm sheets are used for the production of containers, bottoms drawers, door and wall cladding, as well as for furniture facades.
Thickness 16 mm is widely used in the manufacture of furniture, for the construction internal partitions and as a substrate for flooring (linoleum or laminate). Sheets 18 mm thick can also serve as the basis for flooring, but most often they are used for the manufacture of cabinet furniture, including sliding wardrobes. 22mm slabs are suitable for making kitchen furniture, countertops, tables.
For load-bearing elements, window sills and doors, 25 mm thick slabs are used. But for the manufacture of durable bar counters, reliable shelves and tabletops optimal choice will become sheets of laminated chipboard 38 mm. They will be able to withstand the strongest mechanical loads without deforming. It is worth noting that the most popular are laminated chipboard sheets with a thickness of 10, 16, 18 and 25 mm.
An important characteristic in the manufacture of furniture and various construction and repair work is also the weight of the slab. It is determined by the dimensions of the sheet and its density. On average, the weight of one sheet ranges from 40 to 90 kg. For example, the weight of 1 square meter of 16 mm chipboard is on average 10.36-11.39 kg. With a slab thickness of 18 mm it will be 11.65-12.82 kg, 25 mm - from 14.69 to 16.16 kg. This figure will vary slightly among different manufacturers.
Helpful advice! Before you buy laminated chipboard, you need to correctly calculate its size. This will not only ensure the strength and durability of the finished product, but will also help to avoid unnecessary financial costs, guarantee a minimum of material residues and significantly save time.
How to choose and buy chipboard: leading manufacturers
As mentioned above, each manufacturer releases its own variants of laminated chipboard sizes to the market, which is determined by the capabilities of its equipment.
The characteristic dimensions of the Egger chipboard sheet are 2800x2070 mm. Such a unified size does not prevent the Austrian company from successfully competing in the European and domestic markets. Indeed, in addition to excellent environmentally friendly raw materials and huge assortment color solutions, it offers its customers and a good choice slab thickness options - 10, 16, 18, 25 mm and even non-standard 19 mm, which also distinguishes its products from competitors.
In contrast to the only universal size of Egger chipboard, the Syktyvkar plywood plant offers its customers a choice of 3 sizes of Lamarti chipboard - 2800x2070, 2750x1830 and 3660x1830 mm with a thickness of 10, 16, 18 and 26 mm. Affordable prices, high-quality raw materials and a wealth of color solutions allow Lamarti laminated chipboards to successfully fight for their place in the domestic market with foreign companies.
Furniture manufacturers who use chipboard as the main material pay attention not only to the thickness of each sheet, but also to its weight. When indicating the quality characteristics of a particular brand of wood boards, the manufacturer always provides data on the weight of the product. Most often, weight is indicated in kilograms per 1 square meter of slab. Accordingly, it will be quite easy to calculate.
Factors affecting the weight of chipboard
The total mass of particle board depends on several factors, among which are:
- the type of wood used as raw material in the production of chipboard. Each type of wood has a unique structure and fiber density, which causes differences in the weight of shavings and sawdust from pine, linden, oak, etc.
- compaction density of wood pulp during the process of board formation. The more air remains between the wood particles mixed with the glue, the lighter the final weight of the board will be.
- the size of each individual sheet of chipboard - that is, the number of square meters in one slab. The shorter the length, width and thickness of the slab, the less its total weight.
Chipboard weight from leading manufacturers
Analyzing the weight of wood boards, it can be noted that each manufacturer, depending on the characteristics of its technological process, offers products of different weights. In the table below, we have tried to systematize information about the mass of different formats of wood-based panels from leading manufacturers.
| Manufacturer | Slab format, mm | Weight, kg | |
|---|---|---|---|
| per 1 m2 | on the stove | ||
| Swisspan | 2440x1830x25 | 16,16 | 72,2 |
| 2440x1830x22 | 14,22 | 63,5 | |
| 2440x1830x18 | 12,82 | 57,2 | |
| 2440x1830x16 | 11,39 | 50,9 | |
| 2750x1830x22 | 14,22 | 71,6 | |
| 2750x1830x18 | 12,82 | 64,5 | |
| 2750x1830x16 | 11,39 | 57,3 | |
| 2750x1830x10 | 7,8 | 39,3 | |
| Egger | 2800x2070x10 | 7,09 | 41,1 |
| 2800x2070x16 | 10,36 | 60,0 | |
| 2800x2070x18 | 11,65 | 67,5 | |
| 2800x2070x19 | 12,3 | 71,3 | |
| 2800x2070x25 | 14,69 | 85,1 | |
The table shows that the weight of slabs with the same format can differ significantly due to differences in thickness. In addition, wood boards of the same thickness, but made by different manufacturers, also have different weights per square meter.
Thus, the indicator of how much a chipboard sheet weighs depends on many reasons. Experienced furniture manufacturers often rely on its value when assessing the quality of a batch of chipboards. Too much weight of the slab may indicate a violation of the drying technology in the production of chipboard, and too light a slab may be brittle and brittle.
