6 best OSB plates
OSB boards are made of flat chips, joined by various resins, synthetic wax and boric acid. The material consists of 3-4 layers, pressed by pressure when heated raw materials. To increase the strength of the panels, the layers are alternated longitudinally and transversely. Due to the large flat fractions, the sheets look less attractive than MDF, but they are cheaper. We have prepared a ranking of the best OSB boards, which will show the clear advantages and features of popular products. To make the TOP-6, our experts analyzed the characteristics of the panels and customer reviews, so the information will help narrow down the search and immediately purchase the best product.

Kronospan OSB-3 1220 * 2440mm 9mm
Rating: 5.0
The first place is taken by OSB cooker, produced in Russia, but under license from a European manufacturer. The panel is designed for low-rise construction and has a standard height of 2.44 m, filling the distance from the floor to the ceiling in most homes. According to the class of environmental friendliness the product belongs to E1 and is completely safe for children's rooms. OSB panel is stable in size and uniform color. Wizards praise the goods for smooth and rough sides in reviews, thanks to which it is convenient to pull the material over the surface (less resistance) and walk safely from above (for example, on the roof, which you later need to trim with roofing material or tile). The vapor-permeable structure of the slab ensures the removal of moisture from the room.
We ranked OSB plate from this manufacturer in the rating due to the use of Canadian technology in the manufacture. This provides high strength compound chips and gives a grayish color to wood. If OSB is treated with a transparent varnish, then it will get a decent look and be able to serve as decorative decoration of the walls of the room without additional materials.
Virtues
- homogeneous structure of the ends;
- belongs to the 3rd class suitable to the increased humidity;
- one side is rough, which increases safety when installing on the roof;
- attractive price;
- vapor permeability.
disadvantages
- only suitable for non-loadable structures;
- when covering the roof will require frequent crate with a step of 30 cm;
- weak stiffness due to thin section.
Isoplat thorn groove from 4 sides 1800x600x50 mm
Rating: 4.9
In the second place of the ranking, the plate is slightly smaller than the leader, but with a thicker section of 5 cm. The OSB is able to perform the role of a supporting structure and requires minor sheathing walls with a step of 55 cm. The density of the material is 230 kg / m³. Builders in the reviews praise the product for sound absorption 22-54 dB. A good OSB stove also prevents heat transfer due to a thermal conductivity of 0.049 W / m * K, which equates to glass wool. The porous structure of the OSB allows building structures to participate in the regulation of humidity. One slab can cover an area of 1.08 m², which makes it easy to count for purchases.
Our experts included OSB in the rating, as the best fastening.Due to the presence of spikes and grooves on each side, the panels are easily interconnected without the formation of "cold bridges". This increases the heat and sound insulation characteristics. Thanks to the thickness of 5 cm, OSB is universal for the construction of any part of the house: flat and sloping roofs, external walls for plaster, interfloor floors, and the floor over concrete screed.
Virtues
- prevents the formation of condensate;
- prevents the appearance of "cold bridges";
- keeps you cool in summer and warm in winter;
- does not cause allergic reactions.
disadvantages
- high price;
- inevitable trim, depriving one of the sides of the connecting element;
- each slab weighs 12 kg - it is more difficult to plant on the roof or second floor.
Glunz 1250x2500x22mm
Rating: 4.8
The third place in the ranking of the best was taken by the stove from the German manufacturer Glunz. OSB is available with dimensions of 1.25x2.5 m and a cross section of 2.2 cm. It can be installed as a carrier floor or ceiling. According to the class of emission refers to E1 and is completely safe for residents. If you buy in bulk for large-scale construction, then there are pallets that hold 44 pieces. The OSB plate is cut with a saw blade on a grinder, manual circular saw and even a jigsaw. If the sheets are fastened to the walls at the stage of a subfloor, then the plates, 2.5 m high, just stand between the ceiling and the floor. But users in the reviews warn that when installing the panels on the walls with the floor laid, you will have to cut the end by 1-2 cm.
According to our experts, OSB has earned a place in the ranking of the best due to increased moisture resistance. The structure of the sheet includes wood chips impregnated with paraffin, which improves resistance to water absorption and swelling. This is the best option for finishing the ceiling or walls of the bathroom and kitchen of a private house.
Virtues
- German quality;
- one sheet covers 3 square meters at once;
- suitable for supporting structures;
- without harmful additives.
disadvantages
- most often sold in bulk from 20 sheets;
- high price;
- there are large slivers in the outer structure, spoiling the view.
Kronospan 1220x2440x15 mm
Rating: 4.7
In the fourth place of our rating, the goods from the Latvian brand, produced at production facilities in Russia (Mogilyov), were placed again. Sheet thickness is 15 mm. OSB is made entirely from softwood and has a pleasant smell. The height of the slab is suitable for wall cladding after the floor has been laid and does not need to be trimmed. In the production of OSB material is so pressed that it acquires a density of 585 kg / m³. The moisture resistance class at the stove is third, therefore we allow installation in the bathroom or kitchen. To turn the OSB plate in half, a force of 20 MPa is required, and this cannot be reproduced by hand. The panel is suitable not only for interior decoration, but also for exterior work that buyers like in reviews.
Our experts included the plate in the ranking of the best OSB because of the special smoothness of the front surface of Super Finish, which allows you to open it with a transparent varnish and no longer handle it. It is already ready material for finishing finishing of walls and a ceiling in frame construction. The cross section of 1.5 cm withstands force up to 3500 MPa, so the panels can carry not only a decorative function, but keep the shape of the floor under linoleum.
Virtues

- poor sound insulation 0.3-23 dB;
- increased thermal conductivity - 0.1 W / m * K.
OSB-3 Kalevala 2500х1250х9 mm
Rating: 4.6
Fifth place in the rating, we gave the plate of OSB from the Russian manufacturer, which has domestic and international (EN-300) certificates. It produces OSB with unpolished sides, so additional decoration will be required for interior decoration. But on the elasticity of the product far exceeds its competitors. The special technology of pressing does not allow splitting of chips even with a significant bending of the surface.Masters in the reviews are divided, then the sheets are easily drilled, sawn and polished. OSB surface is allowed to be painted and varnished, which expands the use of plates.
Experts liked the product with its increased density of 650-700 kg / m³. This is due to the use of wood growing in the harsh northern conditions of Karelia. Slivers of local breeds are much stronger than European pine. The elasticity and elasticity of sheets provided 10% synthetic resin, which increases moisture resistance. This OSB is optimal for the manufacture of high-quality packaging, designed for the transport of fragile goods.
Virtues
- keeps stable dimensions;
- OSB waterproof;
- 90% consists of wood;
- formaldehyde content corresponds to class E1.
disadvantages

- each plate weight is 20 kg.
Ultralam 1250x2500x12 mm
Rating: 4.5
The sixth place in the ranking is taken by the OSB cooker from the manufacturer Ultralam. Construction sheets have a uniform structure and a unique surface pattern. The laid fibers along the length of the slab and the transverse inner layer are much stronger than ordinary wood with multidirectional veins. OSB of this type can be used in a humid environment. Due to the high density of the product belongs to the low-fuel class. Buyers in the reviews note the high ability to hold fasteners (screws, nails) in the material. The slab is not prone to cracks and chips, since it has no voids.
Experts added OSB rating for increased environmental safety. Unlike top competitors, the free formaldehyde emission class here is 0.5, versus 1.0 for other products. The main raw material for the production of OSB is birch, aspen and alder. And the strength of the connection of the chips is achieved by high temperature and low tar content. This is the best OSB for finishing bedrooms or making furniture frames.
