Sizes of OSB sheets

Knowing the dimensions of OSB sheets is very important for the correct selection and use of these valuable products. In order not to be confused with the dimensions of OSB sheets, it is required to take into account the standard width and length of OSB boards. You also need to pay attention to the height standards and take into account how many squares are in one OSB panel.

The dimensions of OSB boards can be quite different from different manufacturers. One of the most important parameters is thickness. It is by her that they judge the possibility of using the product in a particular case. Of key importance when choosing are:

• distance separating the supports;
• the level of load on the slab;
• bearing capacity of a particular specimen.

The exact characteristics of the material can always be obtained from its direct manufacturers. The width of oriented strand board is 1200 mm in European countries. According to the same EU standard, its length will be 2500 mm.

A slightly different approach has been adopted in the United States. There, the length of the sheet is taken to be 244 cm. Its width, according to the American standard, will be 1220 mm. The multiplicity of the sides was not chosen by chance - it is much more convenient to build frames this way. In this respect, OSB is much more practical than drywall sheets.

In some cases, manufacturers deviate from generally accepted foreign standards. The result is a product with a length of 3000 mm. Sometimes it is further increased - up to 3150 mm. And there is also an opportunity to order a completely atypical slab, the length of serially produced to order products occasionally reaches 700 cm.The need for them is mainly associated with the construction of high partitions and with decorating walls in tall buildings, including outside.

Spans - this means the distance between the main load-bearing elements of the frame. The special markings, applied directly to the sheets themselves, visually help to clarify the attachment points of the racks. If there are two numbers, then the first of them shows the required span on the roof, and the second - indoors.

When selecting sheets for decorating rooms, it is recommended to choose plates of the largest possible size. This will ensure the minimum number of joints. Each such joint is a potential weak point from a mechanical and thermal point of view. In terms of thickness, the most popular level is 9 mm. Such panels are quite acceptable in terms of strength and reliability.

Laying on fine expanded clay or sand generally implies the use of OSB 6 or 8 mm. The first option is cheaper, but the second is more reliable. For leveling heavily skewed wooden floors, a 15 or 18 mm cover is required. As for the design of the floor along the logs, the layer of material should be selected in accordance with the distance between them.

So, a step between the lags of 400 mm means that you can get by with 18 mm products. When building up such a gap, the thickness of the slabs must also be increased. So, when the logs are divorced by 600 mm, it is already required to use the material with a layer of 22 mm. As for the width, you need to pay attention to compliance with this or that standard. Well, it is recommended to take the length equal to or proportional to the dimensions of the surfaces to be closed.

The firm "Kronospan" supplies OSB with dimensions of 2500x1250 mm.It is such a product that is produced at the Mogilev enterprise of the concern. The thickness of the products can be equal to:

• 9;
• 10;
• 12;
• 15;
• 18;
• 22;
• 25 mm.

But the concern is also producing in Yegoryevsk. There, the typical product size is 2440x1220 mm. In this case, the thickness is equal to:

• 9;
• 12;
• 15;
• 18;
• 22 mm.

Quite often there are OSB sheets from this manufacturer at construction sites, at repaired objects. And just their parameters differ very, very noticeably. It is at the enterprises of "Kalevala" that oriented wood-based panels with a thickness of 8 mm are made. Its length (that is, the mounting height on the wall) and width are standard for Russia - 2500 and 1250 mm, respectively. Also in the line of the Kalevala "standard format" there are also slabs:

• 9x2500x1250;
• 12x2440x1250;
• 12x2500x1250;
• 12x2800x1250;
• 15x2500x1250;
• 18x2500x1250;
• 22x2500x1250.

In other lines of this manufacturer, the set of sizes is slightly smaller. So, in the group designated as DIY format, there are plate models with a size (in centimeters):

• 0.9x250x62.5;
• 0.9x125x125;
• 1.2x250x62.5;
• 1.2x125x125;
• 1.2x250x62.5 (ШП2 and ШП4).

The smallest number of models is the Thorn-Groove line. In fact, there are only two of them in it: ШП2 and ШП4. Both have a size of 1.2x250x125 cm. It is also worth taking a closer look at the Eco-House collection. Oriented slabs of this type are made taking into account the requirements of the emission class E0.5.

There are 3 models presented in the Eco-House group (in millimeters):

• 9x2500x1250;
• 12x2500x1250;
• 12x2800x1250.

This is a solid German brand of OSB-sheet. And in general, they approach the selection of the size range of their products quite thoughtfully. The thickness of the slabs can be:

• 6;
• 9;
• 10;
• 12;
• 15;
• 18;
• 22 mm.

As you can see, pragmatic Germans, along with the size positions widely offered by other brands, also promote one that is not found in competitors or is found very limited.

This company supplies boards made according to the European standard. Their size is therefore equal to 2500x1250 mm. The most popular positions in thickness - 9 and 12 mm... They are so common that they even play a major role in the secondary market. But, of course, you can easily buy products with a thickness of 18 mm, as the manufacturer seeks to close all the main positions.

This manufacturer covers all major positions in thickness - from 6 to 22 mm inclusive. Its peculiarity is that 11 mm slabs are also offered, which do not appear in all of the above companies. Plain sheets OSB-3 from Ultralam have dimensions of 2500x1250, 2800x1250, 2440x1220, 2500x625. The thorn-groove line includes models 2500x1250, 2500x625 and a unique plate 2485x610 - it is difficult to find analogues in serial models. It is only necessary to clarify what thickness the sheet can have at a certain length and width.

The topic of the area of ​​a particular sample of slabs is not as minor as it seems. It is important to consider it:

• when calculating the consumption of material and the need for it;
• when assessing the required storage area;
• when determining the possibility of transportation by vehicles with a particular capacity in sq. m.

Typical values ​​can be calculated without the slightest problem. Let's say it is decided to use an oriented slab with a size of 244x122 cm. Then there will be 2.97 squares in one sheet. If you increase the first figure to 250, and the second to 125, then you get 3.125 m2. The rarest version from Ultralam has an area of ​​1.51585 sq. m; if you take a block of 2500x625, you get 1.5625 m2. As you can see, it is not difficult to determine all the necessary parameters for the practical application of oriented strand elements.
