Application of sheets of different thicknesses
To choose the right sheet of material, you need to know its optimal thickness. It affects the strength of the board during transportation, as well as further use. The thicker the slab, the stronger it is, therefore it can be used in more loaded structures. The most popular are the following sheet thicknesses:
8-10 mm - most often used as a material for decorative partitions and unloaded furniture elements;
16-18 mm - common for flooring (especially under linoleum and laminate), as well as the production of most furniture products. The most durable flooring can be obtained by using a 20 mm thicker and heavier board;
22-25 mm - serve as the basis for thick doors, kitchen tables and loaded furniture structures;
28-38 mm - used to create extra strong countertops and shelves that work under heavy loads. Most of the bar counters are made of just such a thick chipboard.
What properties of the sheet depend on the size?
The main parameter that is influenced by the thickness of the sheet is its strength and ability to resist external loads. With increasing thickness, the resistance to deformation increases, but the flexibility decreases.
Thinner chipboard sheets have the ability to bend under mechanical stress. Thick canvases are much less resilient and are more likely to break than bend.
When buying a whole sheet of chipboard, do not forget to take into account the dimensions of the corridors and stairways. Long sheets may not "fit" around corners or break when you try to bend them.
Chipboards have a high hardness, which also increases with increasing thickness. When hitting heavy and thick slabs, only small dents are likely to remain, while thin slabs can break through.
Calculation of the required amount of chipboard
To calculate the required amount of material, you can go in two ways - calculate the most necessary cuts layout or use special computer programs. In the first case, you will have to show perseverance and ingenuity, since it will be rather difficult to find the optimal arrangement of sawing lines.
When choosing the right material size, draw a cutting plan. Try to keep the lines of different parts as compact as possible. This will increase the ratio of useful surface area obtained to unusable waste. Having located the necessary parts in the drawing within the rectangular shape, you can proceed to the selection of a sheet of suitable sizes for sale.
Calculator
In the absence of a good geometric imagination, layouts of the necessary parts can be cut on paper, observing aspect ratios and a single scale. Cut out figures are quite simple to combine, alternating options for their relative position.
Programs with which you can determine the cutting pattern are intended for interior design. The required number and shape of parts are entered into them, after which the optimal layout scheme on a canvas of specific dimensions is automatically calculated. A similar method is used in hardware stores, which cut materials at the request of the client.
Comparison of prices for chipboard sheets of various sizes and manufacturers
The cheapest slabs are 10 mm thick. Cloths of 8, 12 mm and more are more expensive. Consider the prices (rubles per sheet) of some common sizes of chipboard of the most "popular" thickness of 16 mm.

There are differences between the prices of chipboard from different manufacturers - the further the plant is located, the higher the cost will be after transportation to another region. Foreign manufacturers are distinguished by even higher prices, but not always the best quality. When planning work, be guided by the materials available for sale - usually 4-6 sheet sizes are available, and the rest are brought on order.
Look for a chipboard manufacturer in your area before buying. Delivery of large quantities from the factory is much cheaper than that of resellers.
Planning the chipboard cutting scheme is an important stage in construction and repair. The correct approach to sizing allows you to minimize material waste while reducing financial costs. Adequate choice of blade thickness will optimize the weight and strength of the structure. The cost of the material increases with the growth of dimensions and depends on the manufacturer.
Advantages and disadvantages
The advantages of laminated chipboard include a low price, a variety of colors and textures, water resistance, resistance to mechanical damage. All in all, this is a good choice for both finishing work and furniture.
There are also disadvantages:
-
Sheet material. To make panels or furniture, you have to cut it out. You can do it yourself even with the help of an ordinary hand saw, but at the same time, laminate chips form along the edge, which does not improve the appearance of the product in any way. Therefore, you have to order the cutting of laminated chipboard in furniture shops. The service is not too expensive, but it is an additional cost.
- The laminated surface is highly resistant to water and water vapor. But the unprotected end absorbs moisture very well, as a result, the edges swell. Therefore, when cutting, it is also necessary to order edging of all ends. Let it be a melamine end flange, but the cut must be protected.
-
No matter how well the butt is glued, water vapor still penetrates through it. If the furniture is placed in a damp room, the edges will swell over time and the appearance of the furniture or decoration will deteriorate.
- Furniture made of laminated chipboard does not tolerate re-assembly very well. Once you unscrew the screw, you will not tighten it a second time: it will wobble. Larger fasteners can be used. This will help to some extent. You can drill other holes - one centimeter next to it. But, as you know, this does not guarantee a 100% result.
- You won't be able to make curly furniture or smooth, rounded lines from laminated plates - this is not the right material. You can decorate with overlays, fittings. No other way.
Generally speaking, chipboard is a good budget option for interior decoration or for creating furniture.
Production technology
For the production of laminated chipboard (chipboard), a first-class raw material is used - chipboard. It should be without signs of marriage, delamination, extraneous inclusions, etc. Plates are ground, then fed to the press, where the lamination process takes place.
The chipboard sheet is covered with specially treated paper. The color can be different - from monochromatic, to recreate natural materials: wood of different species, stone, cork, etc. Maybe with some kind of pattern. The paper is impregnated with melamine, a substance that does not dissolve in water and most solvents. This impregnation makes the lamination paper strong and moisture resistant.
Melamine paper is laid on the prepared sheet, then fed to the press
The prepared chipboard sheet is placed in a special press, a sheet of melamine paper is placed on top. Next, the press comes into play. These are two horizontally located slabs. On the lower surface of the upper slab, if necessary, a textured pattern is applied, imitating the structure of wood, stone, etc. Oil heated to high temperatures circulates inside the press plates (140-230 ° C).
The texture and color of chipboard may be different
The lower, movable part of the press raises the material laid on it and, for a few seconds, presses it against the upper part of the press. The pressure is high - more than 20 atm, so that the applied textured pattern is pressed into the slab. At the same time, the heating melts the melamine and the surface layer of the "base" chipboard. Melamine penetrates the surface, firmly and rigidly anchoring the paper to the material. After melamine hardens, a strong, rigid film forms on the surface, which is difficult to damage even with sharp and hard objects. The process is repeated on the other side, then the edges are processed.
How much does a chipboard sheet weigh?
Kitchen weight
The weight of a kitchen set naturally depends on its composition. Usually, the weight of an average Russian kitchen varies in the region of 400-550kg (with a total length of mounted furniture of 4-5 meters along the wall). To inform the transport company, an average value of 500 kg is used, while the volume of cargo is in the region of 1.5-2 cubic meters. The maximum package length in 99% of cases does not exceed 4 meters, and a car with a maximum body length of 3.5 meters is used for transportation (in 90% of cases, transportation in a body no more than 3 meters long is allowed).
For more accurate calculations, you can use the following values: Weight of one cubic meter of chipboard (frames and other materials made of chipboard) = 600 kg Weight of one cubic meter of MDF (facade panels of the AlvaColor series) = 750 kg Weight of one cubic meter of wood (facade elements of the AlvaNatural series) = 800 kg (for 'heavy' types of wood, in particular oak / beech) Weight of one cubic meter of glass (products from it) = 2000 kg Weight of one cubic meter of artificial stone = 200 kg Weight of one cubic meter of natural stone (products from it) = 2500-3000 kg
Thus, the weight of the facade measuring 72x60 cm for the Mirella kitchen set will be 0.72 * 0.6 * 0.018 * 600 = 4.6 kg, and taking into account the packaging and fittings (handles), it can pull all 5 kg, with a volume of 0.012 m3. For reference, the weight of the 60cm base cabinet frame is 19.4kg, taking into account additional fittings, it can be rounded up to 20kg, with a volume of 0.047m3. The weight of one meter of 38mm laminated tabletop is 1 * 0.6 * 0.038 * 600 = 13.68kg, taking into account the packaging, it can be rounded up to real 14kg / m. The weight of the hob is 7-10kg, with a volume of 0.06m3. The weight of the built-in oven is 30-40kg, with a normal volume of 0.25m3. The weight of the built-in refrigerator is from 40 to 80 kg, depending on the size and model, the volume of the package is not less than 0.26 m3 and reaches 0.8 m3. The weight of the dishwasher is 35-50kg, with a volume of 0.21-0.26m3. The weight of a sink made of artificial granite is 6-12kg, with a volume of 0.07-0.2m3. When calculating the weight of products made of glass, or containing glass (front-showcase), the weight of the packaging should be taken into account. This usually adds 12-20kg per 1m2 of packaging.
To obtain more accurate data for, for example, air transportation, we recommend that you contact your regional distributor with an appropriate request, who will calculate the exact weight and dimensions of any particular order.
Custom countertops
Standard is not always good. After all, this is an average option that does not take into account some features: kitchen layout, human height, etc.
The tips listed below will help you take into account important nuances when choosing this item.
Tip 1: Dimensions must match the area of the room
Soviet-built houses differ in the area of kitchen facilities, which are much smaller in comparison with modern ones. Here it is worth thinking about reducing the width of the headset to a comfortable level, up to 30-40 cm.
In stores, you can find a narrow, but deep and long sink and a stove that fits the new dimensions.
For large rooms with an island kitchen, you can order a wide worktop. It looks very elegant in classic interiors.
Tip 2: Consider the planner
Depending on the layout (narrow, square, rectangular room), a frontal or angular arrangement is chosen.For a small young family, you can extend the countertop to the bar counter.
Tip 3: Consider the individual characteristics and preferences of the household
The level of the countertop above the floor will affect the convenience of food preparation. The standard height is 85 cm.
What are the dimensions?
As a rule, chipboard sheets on sale are found in their entirety. If you need a small piece of the slab, you still have to purchase the whole one. The required area of the canvas can be found only in large industries dealing with wood and materials from it.
No matter what chipboard plates are used for, it is important to know their dimensions, or rather the length, width and thickness. This will greatly simplify the work with this material.
Typically, the sheets are 183 to 568 centimeters long and 122 to 250 centimeters wide.
The variety of sizes allows you to better select the sheets so that they fit together. Among the sizes, slabs of 244 by 183 cm, 262 by 183 cm, 275 by 183 cm are considered universal, which are convenient to transport and, if necessary, are easy to saw. The dimensions of the slabs are usually determined by the state standard. If the sheet complies with this standard, then it can be considered high quality.
Length
Standard chipboards, both sanded and unsanded, have a length of 180 centimeters or more. At the same time, it can be increased in steps of 10 millimeters. As for laminated boards, their length varies from 183 cm to 568 cm. The error of this parameter, according to the standard, does not exceed 5 mm.
The most popular are chipboard sheets with a length of 275 cm, 262 cm, 244 cm. It should be clarified that each manufacturer produces sheets of certain parameters. So, Swisspan prefers sheets with a length of 244 and 275 cm, and Egger - 280 cm.For slabs produced by Kronospan Russia, the length is strictly 280 and 262 cm.
Width
The width of particle boards can vary from 120 to 183 centimeters. In this case, deviations from the standard cannot exceed 5 millimeters. The greatest demand among consumers is for sheets with a maximum indicator of 183 cm. Swisspan also prefers this width. At Egger, the slab format assumes only one standard value - 207 cm, while Kronospan Russia uses both of these widths.
Thickness
The thickness of the chipboard is from 1 to 50 millimeters. In this case, the step is only one millimeter. The maximum demand is observed for slabs with a thickness of 16 mm. The Swisspan trademark produces chipboards with a thickness of 10 mm, 16 mm, 18 mm, 22 mm and 25 mm, and the manufacturer Egger, in addition to the usual thickness, has 19 mm boards. Kronospan Russia, in addition to the above, produces sheets with a thickness of 8 mm, 12 mm and 28 mm.
Plain chipboard sheets, as a rule, have a thickness of 1 mm. For laminated sheets, it starts from 3 mm. A thickness of 40 mm or more is required for products where increased reliability is important, but they are not used very often.
Why is it important to know the dimensions of the sheet before starting work?
Chipboards are almost always sold whole. Even if you need a small piece of slab, most often you have to buy the entire canvas. Sometimes in large factories dealing with the sale and sawing of wood, you can pay only for the actual area of the cut sheet. The leftovers after sawing are used in production or are initially included in the cost for the buyer.
Construction and repair work is a separate area of activity - flooring and wall cladding. To calculate the size and the required number of sheets, you will have to carefully measure the length and width (height) of the surfaces. By choosing the optimal dimensions and the number of cuts, you can significantly simplify the work of laying the material.
MDF characteristics
Plates of medium density from a mixture of fine chips and polymer binders are called MDF (Medium Density Fiberdoard) or MDF in transliteration.They are produced in the form of sheets or panels with a smooth surface with a density of 400-750 kg / m3. The products are distinguished by high strength, moisture resistance, heat capacity. The advantages are also low price and ease of use. Unlike analogues (chipboard or fiberboard), the material is easy to saw, cut, mill.
MDF boards of different thicknesses are used for different purposes
The front part of MDF, used for decoration or cladding, is decorated with:
- Abrasion-resistant enamels on an alkyd or urethane-alkyd base.
- Polymer films fixed using the "lamination" technique. The choice of designs is extensive. You can get a surface with a texture like wood, stone, textiles, leather and much more. Thanks to the assortment, this is the most popular type of front finishing.
- Veneer of valuable species of natural wood (cherry, oak, walnut, mahogany, wenge, jatoba, zebrano and other exotic species).
MDF, used for rough work in construction, decoration, insulation, is not subjected to additional processing.
Among the shortcomings, we note the fire hazard, low bearing capacity and fear of hydration. From constant exposure to water, the plates swell, warp, mold and fungi may appear.
Scope of application
Exceptionally positive performance properties of MDF, combined with environmental friendliness and affordability, have made these boards popular in a wide variety of sectors of construction, interior decoration and industry. The wide assortment made it possible to widely use the panels during repair and finishing works, as well as for the manufacture of furniture.
The ability to sound absorption and thermal insulation led to the use of the material for the production of wall plates, doors, interior partitions and other decorative elements.
MDF, due to its high density, is considered the optimal material for the production of joinery. Also, panels are used for rough laying of floor coverings and final leveling of walls. And, of course, panels are widely used to create office and cabinet furniture.
Hygroscopicity and resistance to mold and mildew have led to the popularity of slabs in the production of furniture for medical institutions, laboratories, as well as living rooms with a high humidity index (bathroom and kitchen).
The scope of use of MDF is wide and varied:
- sheet-type panels are widely used for laying ceilings and floors;
- wall decoration with MDF plates is very common;
- used as a connecting material for the formation of frame facades;
- production of all types of furniture;
- for soundproofing rooms - panels significantly reduce the audibility between rooms, therefore they are used in panel houses, as well as for covering the walls of the parent's bedroom in houses with children;
- an unusual scope of application of the material - the restoration of old steel doors, MDF is used as a coating, transforming and updating the look of an old door that has lost its luster;
- for the arrangement of slopes.
When using panels, the parameters of length, width and thickness of the material come to the fore. If there are practically no restrictions for wall cladding (the size of the slabs depends on the personal preferences of the owner of the room), then for other categories the scope requires specific dimensions:
- kitchen aprons - it is optimal to use slabs 3 m long, 60 cm wide and 6-10 mm thick;
- countertops - this element is subject to loads and pressure, therefore, a panel thickness of 28-38 mm is required here, the length and width parameters, as a rule, are 1 meter and 60 cm, respectively;
- doors - interior doors made of MDF are manufactured in accordance with the accepted standard: the thickness is 35-45 cm, the length is 190-200 cm, and the width is 70-90 cm.
The material belongs to the category of wear-resistant, however, it has been noticed that morally it becomes obsolete before it wears out physically. That is why it (in the overwhelming majority of cases) is used for cladding non-residential premises: an entrance hall, a corridor, a bathroom, loggias and balconies, as well as utility blocks.
How much does the chipboard weigh?
To improve the physical and mechanical properties, synthetic resins are introduced into the composite (the amount of resin varies from 4% to 8%, depending on the ratio of coniferous-deciduous fibers). In the production of soft boards, the binder may not be used, due to the bonding of lignin, which is part of the fibers, at high temperatures. Special additives are also used, such as fire retardants, antiseptics. For the production of superhard fibreboard (grade ST), impregnation is used with a by-product of processing tall oil - pectol. The strength of the slabs increases by 20 - 30%.
Fiberboard TS - A, B (hardboard) - solid wood fiber board of the wet method of production, without the addition of a binder, the surface of which is smoothed on one side (front). Fiberboard is used in construction, especially low-rise residential, for fencing and decoration, furniture production, door canvases, office partitions, exhibition stands.
Fiberboard marking
Fiberboard sheets can be divided into two subgroups. These are soft fibreboards and hard fibreboards. Soft fiberboard sheets are divided depending on the density into M-1, M-2 and M-3. If we talk about solid fiberboard boards, then here it is much more difficult. Hard fiberboard sheets can be divided into the following brands:
T - hard slabs with a non-refined front surface; Т-С - hard slabs with face a layer of finely dispersed wood pulp; T-P - hard slabs with a tinted face layer; T-SP - hard boards with a tinted front layer of finely dispersed wood pulp; ST - superhard fiberboard (hard board of increased strength) with an unrefined front surface; ST-S - hard boards of increased strength (superhard) with a front layer of finely dispersed wood pulp. The quality division of wood-fiber boards of grades T, T-C, T-P, T-SP is carried out directly into groups: A and B.

Chipboard: dimensions and thickness of the sheet, the price of the material
Normative documents that regulate the geometric dimensions of the chipboard sheet define 18 gradations in length and 9 in width. The length of the sheets is in the range of 1830-5680 mm, the width starts from 1220 and reaches 2500 mm.
Chipboard sheet can have a thickness of 10, 16, 18, 22, 25 and 28 mm
Chipboard sheets of standard sizes can be different in their thickness. This important geometric parameter is also in a wide range. The minimum chipboard thickness is 8 mm, the maximum is 38 mm. The most popular are chipboards with a thickness of 22, 18, and 16 mm.It is this indicator that should be taken into account when choosing a material. It determines the further use of the product and affects to its strength level during subsequent transportation. The thicker the sheet, the stronger it is, which means it can be used in loaded structures.

Chipboard dimensions and sheet price
Several factors influence the formation of the cost of any material. The first of these is the product manufacturing technology (the quality of raw materials, the presence of additional components, the application of a protective and decorative coating). The next criteria include the dimensions and thickness of the sheet, on which the amount of raw materials depends. Also, an important point is the seasonality, which makes its own adjustments to the pricing policy. The next factor is the place where the product is manufactured, on which the transport component of the product price depends. In addition, prices in hardware stores in different cities may differ significantly.
A square meter of a chipboard sheet will cost 135 rubles and more
Depending on the grade, brand and surface of the material, the price for a chipboard sheet can start from 650 rubles.
Price of laminated chipboard sheet size and thickness 2800x2070x16 mm will be about 1,420 rubles. While polished chipboard of the same size will cost 880 rubles. This difference is justified by the costs associated with the technology of applying a certain texture to the surface of the slab.
Comparative characteristics of prices for the most popular chipboard positions are presented in the following table:

As you can see from the table, the material has a very reasonable price per sheet. You can buy chipboard at any hardware store, or place an order on a specialized Internet resource.
The leading chipboard manufacturers are:
The plant "Kronospan", which is located in the city of Yegoryevsk. It offers quality material, which is produced on continuously operating computerized state-of-the-art German equipment. The plant produces chipboard with dimensions of 2440x1830, 2620x2070 and 2800x2070 mm with sheet thicknesses of 10, 12, 16, 18 and 22 mm. You can place an individual order for sheets with a thickness of 8, 25, 28, 32, and 38 mm.
Egger, whose products are produced under the EUROSPAN trademark and are used for the manufacture of furniture parts and repair work. The material has a durable middle layer and thin outer layers, which makes it the most suitable for applying various decorative textures. The company produces slabs with a length of 5600 and 2800 mm and a width of 2070 mm.
The facade of the kitchen is made of moisture-resistant chipboard
Types of chipboard and their scope
Depending on the level of environmental safety, 2 classes of chipboard are distinguished - classes E1 and E2. Particleboard of class E1 is considered the safest, since it contains less formaldehyde resins. The content of harmful substances in E2 class slabs does not allow them to be used in the manufacture of children's furniture. Moreover, in recent years in the EU countries there has been a gradual reduction in its production. In Europe, another class of chipboard boards is distinguished - Super E. Materials of this class are absolutely safe, but they are distinguished by an excessively high cost.
In appearance, chipboard is divided into 3 grades. Plates of the first grade are made only from high-quality raw materials, they have no defects, and at the final stage of production they are covered with a special decorative film or veneer. This grade is used in the manufacture of furniture.
Chipboard and chipboard are widely used for the production of furniture
For slabs of the second grade, cladding is not required, minor scratches or chips at the edges are allowed.Particleboard of the third grade is often made from raw materials containing foreign inclusions or from shavings of tree bark, they have visible defects - chips, cracks, irregularities. The last two grades are used mainly in construction - as a rough finish, flooring, leveling ceilings and walls, and formwork production.
In addition, chipboard slabs are:
- untreated (they are used for rough finishing of premises);
- polished (used in the manufacture of furniture, but only for elements hidden from the eyes);
- laminated (specially processed paper is used as a coating);
